They will be installed automatically when the package is installed. If you wish to use packages that are not available in PyPI, or want to give your users an alternate download location, you can add a 'find_links' option to the '[easy_install]' section of your project's 'setup.cfg' file, and then setuptools will scan the listed web pages for links that satisfy the requirements. 'extras_require' -- a dictionary mapping names of optional "extras" to the additional requirement(s) that using those extras incurs. For example, this:: extras_require = dict(reST = ["docutils>=0.3", "reSTedit"]) indicates that the distribution can optionally provide an extra capability called "reST", but it can only be used if docutils and reSTedit are installed. If the user installs your package using EasyInstall and requests one of your extras, the corresponding additional requirements will be installed if needed. 'features' **deprecated** -- a dictionary mapping option names to 'setuptools.Feature' objects. Features are a portion of the distribution that can be included or excluded based on user options, inter-feature dependencies, and availability on the current system. Excluded features are omitted from all setup commands, including source and binary distributions, so you can create multiple distributions from the same source tree. Feature names should be valid Python identifiers, except that they may contain the '-' (minus) sign. Features can be included or excluded via the command line options '--with-X' and '--without-X', where 'X' is the name of the feature. Whether a feature is included by default, and whether you are allowed to control this from the command line, is determined by the Feature object. See the 'Feature' class for more information. 'test_suite' -- the name of a test suite to run for the 'test' command. If the user runs 'python setup.py test', the package will be installed, and the named test suite will be run. The format is the same as would be used on a 'unittest.py' command line. That is, it is the dotted name of an object to import and call to generate a test suite. 'package_data' -- a dictionary mapping package names to lists of filenames or globs to use to find data files contained in the named packages. If the dictionary has filenames or globs listed under '""' (the empty string), those names will be searched for in every package, in addition to any names for the specific package. Data files found using these names/globs will be installed along with the package, in the same location as the package. Note that globs are allowed to reference the contents of non-package subdirectories, as long as you use '/' as a path separator. (Globs are automatically converted to platform-specific paths at runtime.) In addition to these new keywords, this class also has several new methods for manipulating the distribution's contents. For example, the 'include()' and 'exclude()' methods can be thought of as in-place add and subtract commands that add or remove packages, modules, extensions, and so on from the distribution. They are used by the feature subsystem to configure the distribution for the included and excluded features.

This argument exists to support removing features that "crosscut" a distribution, such as defining a 'tests' feature that removes all the 'tests' subpackages provided by other features. The default for this argument is an empty list.

So, for example, you could pass 'packages=["a","b"]' to cause packages 'a' and 'b' to be added or removed from the distribution as appropriate. A feature must include at least one 'requires', 'remove', or other keyword argument. Otherwise, it can't affect the distribution in any way. Note also that you can subclass 'Feature' to create your own specialized feature types that modify the distribution in other ways when included or excluded.

They will be installed automatically when the package is installed. If you wish to use packages that are not available in PyPI, or want to give your users an alternate download location, you can add a 'find_links' option to the '[easy_install]' section of your project's 'setup.cfg' file, and then setuptools will scan the listed web pages for links that satisfy the requirements. 'extras_require' -- a dictionary mapping names of optional "extras" to the additional requirement(s) that using those extras incurs. For example, this:: extras_require = dict(reST = ["docutils>=0.3", "reSTedit"]) indicates that the distribution can optionally provide an extra capability called "reST", but it can only be used if docutils and reSTedit are installed. If the user installs your package using EasyInstall and requests one of your extras, the corresponding additional requirements will be installed if needed. 'features' **deprecated** -- a dictionary mapping option names to 'setuptools.Feature' objects. Features are a portion of the distribution that can be included or excluded based on user options, inter-feature dependencies, and availability on the current system. Excluded features are omitted from all setup commands, including source and binary distributions, so you can create multiple distributions from the same source tree. Feature names should be valid Python identifiers, except that they may contain the '-' (minus) sign. Features can be included or excluded via the command line options '--with-X' and '--without-X', where 'X' is the name of the feature. Whether a feature is included by default, and whether you are allowed to control this from the command line, is determined by the Feature object. See the 'Feature' class for more information. 'test_suite' -- the name of a test suite to run for the 'test' command. If the user runs 'python setup.py test', the package will be installed, and the named test suite will be run. The format is the same as would be used on a 'unittest.py' command line. That is, it is the dotted name of an object to import and call to generate a test suite. 'package_data' -- a dictionary mapping package names to lists of filenames or globs to use to find data files contained in the named packages. If the dictionary has filenames or globs listed under '""' (the empty string), those names will be searched for in every package, in addition to any names for the specific package. Data files found using these names/globs will be installed along with the package, in the same location as the package. Note that globs are allowed to reference the contents of non-package subdirectories, as long as you use '/' as a path separator. (Globs are automatically converted to platform-specific paths at runtime.) In addition to these new keywords, this class also has several new methods for manipulating the distribution's contents. For example, the 'include()' and 'exclude()' methods can be thought of as in-place add and subtract commands that add or remove packages, modules, extensions, and so on from the distribution. They are used by the feature subsystem to configure the distribution for the included and excluded features.

If it is the URL of a .py file with an unambiguous ``#egg=name-version`` tag (i.e., one that escapes ``-`` as ``_`` throughout), a trivial ``setup.py`` is automatically created alongside the downloaded file. If `spec` is a ``Requirement`` object or a string containing a project/version requirement spec, this method returns the location of a matching distribution (possibly after downloading it to `tmpdir`). If `spec` is a locally existing file or directory name, it is simply returned unchanged. If `spec` is a URL, it is downloaded to a subpath of `tmpdir`, and the local filename is returned.

With pyparsing, you don't need to learn a new syntax for defining grammars or matching expressions - the parsing module provides a library of classes that you use to construct the grammar directly in Python. Here is a program to parse "Hello, World!" (or any greeting of the form C{", !"}), built up using L{Word}, L{Literal}, and L{And} elements (L{'+'} operator gives L{And} expressions, strings are auto-converted to L{Literal} expressions):: from pyparsing import Word, alphas # define grammar of a greeting greet = Word(alphas) + "," + Word(alphas) + "!" hello = "Hello, World!" print (hello, "->", greet.parseString(hello)) The program outputs the following:: Hello, World! -> ['Hello', ',', 'World', '!'] The Python representation of the grammar is quite readable, owing to the self-explanatory class names, and the use of '+', '|' and '^' operators. The L{ParseResults} object returned from L{ParserElement.parseString} can be accessed as a nested list, a dictionary, or an object with named attributes. The pyparsing module handles some of the problems that are typically vexing when writing text parsers: - extra or missing whitespace (the above program will also handle "Hello,World!", "Hello , World !", etc.) - quoted strings - embedded comments z2.1.10z07 Oct 2016 01:31 UTCz*Paul McGuire N)ref)datetime)RLock) OrderedDictAndCaselessKeywordCaselessLiteral CharsNotInCombineDictEachEmpty FollowedByForward GoToColumnGroupKeywordLineEnd LineStartLiteral MatchFirstNoMatchNotAny OneOrMoreOnlyOnceOptionalOrParseBaseExceptionParseElementEnhanceParseExceptionParseExpressionParseFatalException ParseResultsParseSyntaxException ParserElement QuotedStringRecursiveGrammarExceptionRegexSkipTo StringEnd StringStartSuppressTokenTokenConverterWhiteWordWordEnd WordStart ZeroOrMore alphanumsalphas alphas8bit anyCloseTag anyOpenTag cStyleCommentcolcommaSeparatedListcommonHTMLEntity countedArraycppStyleCommentdblQuotedStringdblSlashComment delimitedListdictOfdowncaseTokensemptyhexnums htmlCommentjavaStyleCommentlinelineEnd lineStartlineno makeHTMLTags makeXMLTagsmatchOnlyAtColmatchPreviousExprmatchPreviousLiteral nestedExprnullDebugActionnumsoneOfopAssocoperatorPrecedence printablespunc8bitpythonStyleComment quotedString removeQuotesreplaceHTMLEntity replaceWith restOfLinesglQuotedStringsrange stringEnd stringStarttraceParseAction unicodeString upcaseTokens withAttribute indentedBlockoriginalTextForungroup infixNotation locatedExpr withClass CloseMatchtokenMappyparsing_commonc Cs`t|tr|Syt|Stk rZt|jtjd}td}|jdd|j |SXdS)aDrop-in replacement for str(obj) that tries to be Unicode friendly.

Repeated parse attempts at the same string location (which happens often in many complex grammars) can immediately return a cached value, instead of re-executing parsing/validating code. Memoizing is done of both valid results and parsing exceptions. Parameters: - cache_size_limit - (default=C{128}) - if an integer value is provided will limit the size of the packrat cache; if None is passed, then the cache size will be unbounded; if 0 is passed, the cache will be effectively disabled. This speedup may break existing programs that use parse actions that have side-effects. For this reason, packrat parsing is disabled when you first import pyparsing. To activate the packrat feature, your program must call the class method C{ParserElement.enablePackrat()}. If your program uses C{psyco} to "compile as you go", you must call C{enablePackrat} before calling C{psyco.full()}. If you do not do this, Python will crash. For best results, call C{enablePackrat()} immediately after importing pyparsing. Example:: import pyparsing pyparsing.ParserElement.enablePackrat() TN)r$_packratEnabledrrrrrt)Zcache_size_limitrwrwrx enablePackrats   zParserElement.enablePackratcCstj|js|jx|jD] }|jqW|js<|j}y<|j|d\}}|rv|j||}t t }|j||Wn0t k r}ztj rn|WYdd}~XnX|SdS)aB Execute the parse expression with the given string. This is the main interface to the client code, once the complete expression has been built. If you want the grammar to require that the entire input string be successfully parsed, then set C{parseAll} to True (equivalent to ending the grammar with C{L{StringEnd()}}). Note: C{parseString} implicitly calls C{expandtabs()} on the input string, in order to report proper column numbers in parse actions. If the input string contains tabs and the grammar uses parse actions that use the C{loc} argument to index into the string being parsed, you can ensure you have a consistent view of the input string by: - calling C{parseWithTabs} on your grammar before calling C{parseString} (see L{I{parseWithTabs}}) - define your parse action using the full C{(s,loc,toks)} signature, and reference the input string using the parse action's C{s} argument - explictly expand the tabs in your input string before calling C{parseString} Example:: Word('a').parseString('aaaaabaaa') # -> ['aaaaa'] Word('a').parseString('aaaaabaaa', parseAll=True) # -> Exception: Expected end of text rN) r$rr_ streamliner]r\ expandtabsrtrr r)rverbose_stacktrace)rr-parseAllrrrZser3rwrwrx parseString#s$    zParserElement.parseStringccs@|js|jx|jD] }|jqW|js8t|j}t|}d}|j}|j}t j d} yx||kon| |kry |||} ||| dd\} } Wnt k r| d}Yq`X| |kr| d7} | | | fV|r|||} | |kr| }q|d7}n| }q`| d}q`WWn4t k r:}zt j r&n|WYdd}~XnXdS)a Scan the input string for expression matches. Each match will return the matching tokens, start location, and end location. May be called with optional C{maxMatches} argument, to clip scanning after 'n' matches are found. If C{overlap} is specified, then overlapping matches will be reported. Note that the start and end locations are reported relative to the string being parsed. See L{I{parseString}} for more information on parsing strings with embedded tabs. Example:: source = "sldjf123lsdjjkf345sldkjf879lkjsfd987" print(source) for tokens,start,end in Word(alphas).scanString(source): print(' '*start + '^'*(end-start)) print(' '*start + tokens[0]) prints:: sldjf123lsdjjkf345sldkjf879lkjsfd987 ^^^^^ sldjf ^^^^^^^ lsdjjkf ^^^^^^ sldkjf ^^^^^^ lkjsfd rF)rprrN)r_rr]r\rrrrrtr$rrrr)rr- maxMatchesZoverlaprrrZ preparseFnZparseFnmatchesrZnextLocrZnextlocr3rwrwrx scanStringUsB       zParserElement.scanStringcCsg}d}d|_yxh|j|D]Z\}}}|j||||rrt|trT||j7}nt|trh||7}n |j||}qW|j||ddd|D}djtt t |St k r}zt j rȂn|WYdd}~XnXdS)af Extension to C{L{scanString}}, to modify matching text with modified tokens that may be returned from a parse action. To use C{transformString}, define a grammar and attach a parse action to it that modifies the returned token list. Invoking C{transformString()} on a target string will then scan for matches, and replace the matched text patterns according to the logic in the parse action. C{transformString()} returns the resulting transformed string. Example:: wd = Word(alphas) wd.setParseAction(lambda toks: toks[0].title()) print(wd.transformString("now is the winter of our discontent made glorious summer by this sun of york."))

C{CloseMatch} takes parameters: - C{match_string} - string to be matched - C{maxMismatches} - (C{default=1}) maximum number of mismatches allowed to count as a match The results from a successful parse will contain the matched text from the input string and the following named results: - C{mismatches} - a list of the positions within the match_string where mismatches were found - C{original} - the original match_string used to compare against the input string If C{mismatches} is an empty list, then the match was an exact match. Example:: patt = CloseMatch("ATCATCGAATGGA") patt.parseString("ATCATCGAAXGGA") # -> (['ATCATCGAAXGGA'], {'mismatches': [[9]], 'original': ['ATCATCGAATGGA']}) patt.parseString("ATCAXCGAAXGGA") # -> Exception: Expected 'ATCATCGAATGGA' (with up to 1 mismatches) (at char 0), (line:1, col:1) # exact match patt.parseString("ATCATCGAATGGA") # -> (['ATCATCGAATGGA'], {'mismatches': [[]], 'original': ['ATCATCGAATGGA']}) # close match allowing up to 2 mismatches patt = CloseMatch("ATCATCGAATGGA", maxMismatches=2) patt.parseString("ATCAXCGAAXGGA") # -> (['ATCAXCGAAXGGA'], {'mismatches': [[4, 9]], 'original': ['ATCATCGAATGGA']}) rrcsBtt|j||_||_||_d|j|jf|_d|_d|_dS)Nz&Expected %r (with up to %d mismatches)F) rrlrr match_string maxMismatchesrar`r[)rrr)rHrwrxr szCloseMatch.__init__TcCs|}t|}|t|j}||kr|j}d}g} |j} xtt||||jD]0\}} | \} } | | krP| j|t| | krPPqPW|d}t|||g}|j|d<| |d<||fSt|||j|dS)Nrrroriginal mismatches) rrrrrrr"rra)rr-rrostartrmaxlocrZmatch_stringlocrrZs_msrcmatresultsrwrwrxr s("   zCloseMatch.parseImpl)rr)T)rrrrrrrrwrw)rHrxrl s cs8eZdZdZd fdd Zdd d Zfd d ZZS)r/a Token for matching words composed of allowed character sets. Defined with string containing all allowed initial characters, an optional string containing allowed body characters (if omitted, defaults to the initial character set), and an optional minimum, maximum, and/or exact length. The default value for C{min} is 1 (a minimum value < 1 is not valid); the default values for C{max} and C{exact} are 0, meaning no maximum or exact length restriction. An optional C{excludeChars} parameter can list characters that might be found in the input C{bodyChars} string; useful to define a word of all printables except for one or two characters, for instance. L{srange} is useful for defining custom character set strings for defining C{Word} expressions, using range notation from regular expression character sets. A common mistake is to use C{Word} to match a specific literal string, as in C{Word("Address")}. Remember that C{Word} uses the string argument to define I{sets} of matchable characters. This expression would match "Add", "AAA", "dAred", or any other word made up of the characters 'A', 'd', 'r', 'e', and 's'. To match an exact literal string, use L{Literal} or L{Keyword}. pyparsing includes helper strings for building Words: - L{alphas} - L{nums} - L{alphanums} - L{hexnums} - L{alphas8bit} (alphabetic characters in ASCII range 128-255 - accented, tilded, umlauted, etc.) - L{punc8bit} (non-alphabetic characters in ASCII range 128-255 - currency, symbols, superscripts, diacriticals, etc.) - L{printables} (any non-whitespace character) Example:: # a word composed of digits integer = Word(nums) # equivalent to Word("0123456789") or Word(srange("0-9")) # a word with a leading capital, and zero or more lowercase capital_word = Word(alphas.upper(), alphas.lower()) # hostnames are alphanumeric, with leading alpha, and '-' hostname = Word(alphas, alphanums+'-') # roman numeral (not a strict parser, accepts invalid mix of characters) roman = Word("IVXLCDM") # any string of non-whitespace characters, except for ',' csv_value = Word(printables, excludeChars=",") NrrrFc stt|jrFdjfdd|D}|rFdjfdd|D}||_t||_|rl||_t||_n||_t||_|dk|_ |dkrt d||_ |dkr||_ nt |_ |dkr||_ ||_ t||_d|j|_d |_||_d |j|jkr|dkr|dkr|dkr|j|jkr8d t|j|_nHt|jdkrfd tj|jt|jf|_nd t|jt|jf|_|jrd|jd|_ytj|j|_Wntk rd|_YnXdS)Nrc3s|]}|kr|VqdS)Nrw)rr) excludeCharsrwrxr7 sz Word.__init__..c3s|]}|kr|VqdS)Nrw)rr)rrwrxr9 srrrzZcannot specify a minimum length < 1; use Optional(Word()) if zero-length word is permittedz Expected Frz[%s]+z%s[%s]*z [%s][%s]*z\b)rr/rr initCharsOrigr initChars bodyCharsOrig bodyChars maxSpecifiedrminLenmaxLenrrrrar` asKeyword_escapeRegexRangeCharsreStringrrdescapecompilerK)rrrminmaxexactrr)rH)rrxr4 sT      0 z Word.__init__Tc CsD|jr<|jj||}|s(t|||j||j}||jfS|||jkrZt|||j||}|d7}t|}|j}||j }t ||}x ||kr|||kr|d7}qWd} |||j krd} |j r||kr|||krd} |j r|dkr||d|ks||kr|||krd} | r4t|||j|||||fS)NrrFTr)rdrrraendgrouprrrrr rrr) rr-rrorrrZ bodycharsrZthrowExceptionrwrwrxrj s6    4zWord.parseImplc stytt|jStk r"YnX|jdkrndd}|j|jkr^d||j||jf|_nd||j|_|jS)NcSs$t|dkr|dddS|SdS)Nz...)r)rrwrwrx charsAsStr s z Word.__str__..charsAsStrz W:(%s,%s)zW:(%s))rr/rrKrUrr)rr)rHrwrxr s  z Word.__str__)NrrrrFN)T)rrrrrrrrrwrw)rHrxr/ s.6 #csFeZdZdZeejdZd fdd Zd ddZ fd d Z Z S) r'a Token for matching strings that match a given regular expression.

When the expression is known, it is assigned to the C{Forward} variable using the '<<' operator. Note: take care when assigning to C{Forward} not to overlook precedence of operators. Specifically, '|' has a lower precedence than '<<', so that:: fwdExpr << a | b | c will actually be evaluated as:: (fwdExpr << a) | b | c thereby leaving b and c out as parseable alternatives. It is recommended that you explicitly group the values inserted into the C{Forward}:: fwdExpr << (a | b | c) Converting to use the '<<=' operator instead will avoid this problem.

Example:: countedArray(Word(alphas)).parseString('2 ab cd ef') # -> ['ab', 'cd'] # in this parser, the leading integer value is given in binary, # '10' indicating that 2 values are in the array binaryConstant = Word('01').setParseAction(lambda t: int(t[0], 2)) countedArray(Word(alphas), intExpr=binaryConstant).parseString('10 ab cd ef') # -> ['ab', 'cd'] cs.|d}|r ttg|p&tt>gS)Nr)rrrC)rr5rvr) arrayExprr.rwrxcountFieldParseAction_s"z+countedArray..countFieldParseActionNcSs t|dS)Nr)ru)rvrwrwrxrydszcountedArray..ZarrayLenT)rfz(len) z...)rr/rRrrrirxr)r.ZintExprrdrw)rcr.rxr<Ls cCs:g}x0|D](}t|tr(|jt|q |j|q W|S)N)rzrrrr)Lrrrwrwrxrks   rcs6tfdd}|j|ddjdt|S)a* Helper to define an expression that is indirectly defined from the tokens matched in a previous expression, that is, it looks for a 'repeat' of a previous expression.

Parameters: - strs - a string of space-delimited literals, or a collection of string literals - caseless - (default=C{False}) - treat all literals as caseless - useRegex - (default=C{True}) - as an optimization, will generate a Regex object; otherwise, will generate a C{MatchFirst} object (if C{caseless=True}, or if creating a C{Regex} raises an exception) Example:: comp_oper = oneOf("< = > <= >= !=") var = Word(alphas) number = Word(nums) term = var | number comparison_expr = term + comp_oper + term print(comparison_expr.searchString("B = 12 AA=23 B<=AA AA>12")) prints:: [['B', '=', '12'], ['AA', '=', '23'], ['B', '<=', 'AA'], ['AA', '>', '12']] cSs|j|jkS)N)r)rbrwrwrxryszoneOf..cSs|jj|jS)N)rr)rrlrwrwrxryscSs||kS)Nrw)rrlrwrwrxryscSs |j|S)N)r)rrlrwrwrxrysz6Invalid argument to oneOf, expected string or iterablerq)rrrrNrz[%s]css|]}t|VqdS)N)r)rsymrwrwrxrszoneOf..z | |css|]}tj|VqdS)N)rdr )rrmrwrwrxrsz7Exception creating Regex for oneOf, building MatchFirstc3s|]}|VqdS)Nrw)rrm)parseElementClassrwrxrs)rrrzrrrr5rrrrrrrrrr'rirKr) ZstrsrZuseRegexZisequalZmasksZsymbolsrZcurrrrw)rorxrSsL         ((cCsttt||S)a Helper to easily and clearly define a dictionary by specifying the respective patterns for the key and value. Takes care of defining the C{L{Dict}}, C{L{ZeroOrMore}}, and C{L{Group}} tokens in the proper order. The key pattern can include delimiting markers or punctuation, as long as they are suppressed, thereby leaving the significant key text. The value pattern can include named results, so that the C{Dict} results can include named token fields. Example:: text = "shape: SQUARE posn: upper left color: light blue texture: burlap" attr_expr = (label + Suppress(':') + OneOrMore(data_word, stopOn=label).setParseAction(' '.join)) print(OneOrMore(attr_expr).parseString(text).dump()) attr_label = label attr_value = Suppress(':') + OneOrMore(data_word, stopOn=label).setParseAction(' '.join) # similar to Dict, but simpler call format result = dictOf(attr_label, attr_value).parseString(text) print(result.dump()) print(result['shape']) print(result.shape) # object attribute access works too print(result.asDict()) prints:: [['shape', 'SQUARE'], ['posn', 'upper left'], ['color', 'light blue'], ['texture', 'burlap']] - color: light blue - posn: upper left - shape: SQUARE - texture: burlap SQUARE SQUARE {'color': 'light blue', 'shape': 'SQUARE', 'posn': 'upper left', 'texture': 'burlap'} )r r2r)rrrwrwrxrAs!cCs^tjdd}|j}d|_|d||d}|r@dd}ndd}|j||j|_|S) a Helper to return the original, untokenized text for a given expression. Useful to restore the parsed fields of an HTML start tag into the raw tag text itself, or to revert separate tokens with intervening whitespace back to the original matching input text. By default, returns astring containing the original parsed text. If the optional C{asString} argument is passed as C{False}, then the return value is a C{L{ParseResults}} containing any results names that were originally matched, and a single token containing the original matched text from the input string. So if the expression passed to C{L{originalTextFor}} contains expressions with defined results names, you must set C{asString} to C{False} if you want to preserve those results name values. Example:: src = "this is test bold text normal text " for tag in ("b","i"): opener,closer = makeHTMLTags(tag) patt = originalTextFor(opener + SkipTo(closer) + closer) print(patt.searchString(src)[0]) prints:: [' bold text '] ['text'] cSs|S)Nrw)rrrvrwrwrxry8sz!originalTextFor..F_original_start _original_endcSs||j|jS)N)rprq)rr5rvrwrwrxry=scSs&||jd|jdg|dd<dS)Nrprq)r)rr5rvrwrwrx extractText?sz$originalTextFor..extractText)r rrrer])r.ZasStringZ locMarkerZ endlocMarker matchExprrrrwrwrxrg s  cCst|jddS)zp Helper to undo pyparsing's default grouping of And expressions, even if all but one are non-empty. cSs|dS)Nrrw)rvrwrwrxryJszungroup..)r-r)r.rwrwrxrhEscCs4tjdd}t|d|d|jjdS)a Helper to decorate a returned token with its starting and ending locations in the input string.

Use C{withAttribute} to qualify a starting tag with a required attribute value, to avoid false matches on common tags such as C{} or C{
}. Call C{withAttribute} with a series of attribute names and values. Specify the list of filter attributes names and values as: - keyword arguments, as in C{(align="right")}, or - as an explicit dict with C{**} operator, when an attribute name is also a Python reserved word, as in C{**{"class":"Customer", "align":"right"}} - a list of name-value tuples, as in ( ("ns1:class", "Customer"), ("ns2:align","right") ) For attribute names with a namespace prefix, you must use the second form. Attribute names are matched insensitive to upper/lower case. If just testing for C{class} (with or without a namespace), use C{L{withClass}}. To verify that the attribute exists, but without specifying a value, pass C{withAttribute.ANY_VALUE} as the value. Example:: html = '''

Operators may be unary or binary, left- or right-associative. Parse actions can also be attached to operator expressions. The generated parser will also recognize the use of parentheses to override operator precedences (see example below). Note: if you define a deep operator list, you may see performance issues when using infixNotation. See L{ParserElement.enablePackrat} for a mechanism to potentially improve your parser performance. Parameters: - baseExpr - expression representing the most basic element for the nested - opList - list of tuples, one for each operator precedence level in the expression grammar; each tuple is of the form (opExpr, numTerms, rightLeftAssoc, parseAction), where: - opExpr is the pyparsing expression for the operator; may also be a string, which will be converted to a Literal; if numTerms is 3, opExpr is a tuple of two expressions, for the two operators separating the 3 terms - numTerms is the number of terms for this operator (must be 1, 2, or 3) - rightLeftAssoc is the indicator whether the operator is right or left associative, using the pyparsing-defined constants C{opAssoc.RIGHT} and C{opAssoc.LEFT}. - parseAction is the parse action to be associated with expressions matching this operator expression (the parse action tuple member may be omitted) - lpar - expression for matching left-parentheses (default=C{Suppress('(')}) - rpar - expression for matching right-parentheses (default=C{Suppress(')')}) Example:: # simple example of four-function arithmetic with ints and variable names integer = pyparsing_common.signed_integer varname = pyparsing_common.identifier arith_expr = infixNotation(integer | varname, [ ('-', 1, opAssoc.RIGHT), (oneOf('* /'), 2, opAssoc.LEFT), (oneOf('+ -'), 2, opAssoc.LEFT), ]) arith_expr.runTests(''' 5+3*6 (5+3)*6 -2--11 ''', fullDump=False) prints:: 5+3*6 [[5, '+', [3, '*', 6]]] (5+3)*6 [[[5, '+', 3], '*', 6]] -2--11 [[['-', 2], '-', ['-', 11]]] Nrroz%s termz %s%s termrqz@if numterms=3, opExpr must be a tuple or list of two expressionsrrz6operator must be unary (1), binary (2), or ternary (3)z2operator must indicate right or left associativity)N)rrrrrirTLEFTrrrRIGHTrzrr.r)ZbaseExprZopListZlparZrparrZlastExprrZoperDefZopExprZarityZrightLeftAssocr}ZtermNameZopExpr1ZopExpr2ZthisExprrsrwrwrxrisR;    &       &   z4"(?:[^"\n\r\\]|(?:"")|(?:\\(?:[^x]|x[0-9a-fA-F]+)))*"z string enclosed in double quotesz4'(?:[^'\n\r\\]|(?:'')|(?:\\(?:[^x]|x[0-9a-fA-F]+)))*'z string enclosed in single quotesz*quotedString using single or double quotesuzunicode string literalcCs||krtd|dkr(t|to,t|tr t|dkrt|dkr|dk rtt|t||tjddj dd}n$t j t||tjj dd}nx|dk rtt|t |t |ttjddj dd}n4ttt |t |ttjddj d d}ntd t }|dk rb|tt|t||B|Bt|K}n$|tt|t||Bt|K}|jd ||f|S) a~ Helper method for defining nested lists enclosed in opening and closing delimiters ("(" and ")" are the default). Parameters: - opener - opening character for a nested list (default=C{"("}); can also be a pyparsing expression - closer - closing character for a nested list (default=C{")"}); can also be a pyparsing expression - content - expression for items within the nested lists (default=C{None}) - ignoreExpr - expression for ignoring opening and closing delimiters (default=C{quotedString}) If an expression is not provided for the content argument, the nested expression will capture all whitespace-delimited content between delimiters as a list of separate values. Use the C{ignoreExpr} argument to define expressions that may contain opening or closing characters that should not be treated as opening or closing characters for nesting, such as quotedString or a comment expression. Specify multiple expressions using an C{L{Or}} or C{L{MatchFirst}}. The default is L{quotedString}, but if no expressions are to be ignored, then pass C{None} for this argument.

Classes and methods to define and execute parsing grammars The pyparsing module is an alternative approach to creating and executing simple grammars, vs. the traditional lex/yacc approach, or the use of regular expressions. With pyparsing, you don't need to learn a new syntax for defining grammars or matching expressions - the parsing module provides a library of classes that you use to construct the grammar directly in Python. Here is a program to parse "Hello, World!" (or any greeting of the form C{", !"}), built up using L{Word}, L{Literal}, and L{And} elements (L{'+'} operator gives L{And} expressions, strings are auto-converted to L{Literal} expressions):: from pyparsing import Word, alphas # define grammar of a greeting greet = Word(alphas) + "," + Word(alphas) + "!" hello = "Hello, World!" print (hello, "->", greet.parseString(hello)) The program outputs the following:: Hello, World! -> ['Hello', ',', 'World', '!'] The Python representation of the grammar is quite readable, owing to the self-explanatory class names, and the use of '+', '|' and '^' operators. The L{ParseResults} object returned from L{ParserElement.parseString} can be accessed as a nested list, a dictionary, or an object with named attributes. The pyparsing module handles some of the problems that are typically vexing when writing text parsers: - extra or missing whitespace (the above program will also handle "Hello,World!", "Hello , World !", etc.) - quoted strings - embedded comments z2.1.10z07 Oct 2016 01:31 UTCz*Paul McGuire N)ref)datetime)RLock) OrderedDictAndCaselessKeywordCaselessLiteral CharsNotInCombineDictEachEmpty FollowedByForward GoToColumnGroupKeywordLineEnd LineStartLiteral MatchFirstNoMatchNotAny OneOrMoreOnlyOnceOptionalOrParseBaseExceptionParseElementEnhanceParseExceptionParseExpressionParseFatalException ParseResultsParseSyntaxException ParserElement QuotedStringRecursiveGrammarExceptionRegexSkipTo StringEnd StringStartSuppressTokenTokenConverterWhiteWordWordEnd WordStart ZeroOrMore alphanumsalphas alphas8bit anyCloseTag anyOpenTag cStyleCommentcolcommaSeparatedListcommonHTMLEntity countedArraycppStyleCommentdblQuotedStringdblSlashComment delimitedListdictOfdowncaseTokensemptyhexnums htmlCommentjavaStyleCommentlinelineEnd lineStartlineno makeHTMLTags makeXMLTagsmatchOnlyAtColmatchPreviousExprmatchPreviousLiteral nestedExprnullDebugActionnumsoneOfopAssocoperatorPrecedence printablespunc8bitpythonStyleComment quotedString removeQuotesreplaceHTMLEntity replaceWith restOfLinesglQuotedStringsrange stringEnd stringStarttraceParseAction unicodeString upcaseTokens withAttribute indentedBlockoriginalTextForungroup infixNotation locatedExpr withClass CloseMatchtokenMappyparsing_commonc Cs`t|tr|Syt|Stk rZt|jtjd}td}|jdd|j |SXdS)aDrop-in replacement for str(obj) that tries to be Unicode friendly.

Repeated parse attempts at the same string location (which happens often in many complex grammars) can immediately return a cached value, instead of re-executing parsing/validating code. Memoizing is done of both valid results and parsing exceptions. Parameters: - cache_size_limit - (default=C{128}) - if an integer value is provided will limit the size of the packrat cache; if None is passed, then the cache size will be unbounded; if 0 is passed, the cache will be effectively disabled. This speedup may break existing programs that use parse actions that have side-effects. For this reason, packrat parsing is disabled when you first import pyparsing. To activate the packrat feature, your program must call the class method C{ParserElement.enablePackrat()}. If your program uses C{psyco} to "compile as you go", you must call C{enablePackrat} before calling C{psyco.full()}. If you do not do this, Python will crash. For best results, call C{enablePackrat()} immediately after importing pyparsing. Example:: import pyparsing pyparsing.ParserElement.enablePackrat() TN)r$_packratEnabledrrrrrt)Zcache_size_limitrwrwrx enablePackrats   zParserElement.enablePackratcCstj|js|jx|jD] }|jqW|js<|j}y<|j|d\}}|rv|j||}t t }|j||Wn0t k r}ztj rn|WYdd}~XnX|SdS)aB Execute the parse expression with the given string. This is the main interface to the client code, once the complete expression has been built. If you want the grammar to require that the entire input string be successfully parsed, then set C{parseAll} to True (equivalent to ending the grammar with C{L{StringEnd()}}). Note: C{parseString} implicitly calls C{expandtabs()} on the input string, in order to report proper column numbers in parse actions. If the input string contains tabs and the grammar uses parse actions that use the C{loc} argument to index into the string being parsed, you can ensure you have a consistent view of the input string by: - calling C{parseWithTabs} on your grammar before calling C{parseString} (see L{I{parseWithTabs}}) - define your parse action using the full C{(s,loc,toks)} signature, and reference the input string using the parse action's C{s} argument - explictly expand the tabs in your input string before calling C{parseString} Example:: Word('a').parseString('aaaaabaaa') # -> ['aaaaa'] Word('a').parseString('aaaaabaaa', parseAll=True) # -> Exception: Expected end of text rN) r$rr_ streamliner]r\ expandtabsrtrr r)rverbose_stacktrace)rr-parseAllrrrZser3rwrwrx parseString#s$    zParserElement.parseStringccs@|js|jx|jD] }|jqW|js8t|j}t|}d}|j}|j}t j d} yx||kon| |kry |||} ||| dd\} } Wnt k r| d}Yq`X| |kr| d7} | | | fV|r|||} | |kr| }q|d7}n| }q`| d}q`WWn4t k r:}zt j r&n|WYdd}~XnXdS)a Scan the input string for expression matches. Each match will return the matching tokens, start location, and end location. May be called with optional C{maxMatches} argument, to clip scanning after 'n' matches are found. If C{overlap} is specified, then overlapping matches will be reported. Note that the start and end locations are reported relative to the string being parsed. See L{I{parseString}} for more information on parsing strings with embedded tabs. Example:: source = "sldjf123lsdjjkf345sldkjf879lkjsfd987" print(source) for tokens,start,end in Word(alphas).scanString(source): print(' '*start + '^'*(end-start)) print(' '*start + tokens[0]) prints:: sldjf123lsdjjkf345sldkjf879lkjsfd987 ^^^^^ sldjf ^^^^^^^ lsdjjkf ^^^^^^ sldkjf ^^^^^^ lkjsfd rF)rprrN)r_rr]r\rrrrrtr$rrrr)rr- maxMatchesZoverlaprrrZ preparseFnZparseFnmatchesrZnextLocrZnextlocr3rwrwrx scanStringUsB       zParserElement.scanStringcCsg}d}d|_yxh|j|D]Z\}}}|j||||rrt|trT||j7}nt|trh||7}n |j||}qW|j||ddd|D}djtt t |St k r}zt j rȂn|WYdd}~XnXdS)af Extension to C{L{scanString}}, to modify matching text with modified tokens that may be returned from a parse action. To use C{transformString}, define a grammar and attach a parse action to it that modifies the returned token list. Invoking C{transformString()} on a target string will then scan for matches, and replace the matched text patterns according to the logic in the parse action. C{transformString()} returns the resulting transformed string. Example:: wd = Word(alphas) wd.setParseAction(lambda toks: toks[0].title()) print(wd.transformString("now is the winter of our discontent made glorious summer by this sun of york."))

C{CloseMatch} takes parameters: - C{match_string} - string to be matched - C{maxMismatches} - (C{default=1}) maximum number of mismatches allowed to count as a match The results from a successful parse will contain the matched text from the input string and the following named results: - C{mismatches} - a list of the positions within the match_string where mismatches were found - C{original} - the original match_string used to compare against the input string If C{mismatches} is an empty list, then the match was an exact match. Example:: patt = CloseMatch("ATCATCGAATGGA") patt.parseString("ATCATCGAAXGGA") # -> (['ATCATCGAAXGGA'], {'mismatches': [[9]], 'original': ['ATCATCGAATGGA']}) patt.parseString("ATCAXCGAAXGGA") # -> Exception: Expected 'ATCATCGAATGGA' (with up to 1 mismatches) (at char 0), (line:1, col:1) # exact match patt.parseString("ATCATCGAATGGA") # -> (['ATCATCGAATGGA'], {'mismatches': [[]], 'original': ['ATCATCGAATGGA']}) # close match allowing up to 2 mismatches patt = CloseMatch("ATCATCGAATGGA", maxMismatches=2) patt.parseString("ATCAXCGAAXGGA") # -> (['ATCAXCGAAXGGA'], {'mismatches': [[4, 9]], 'original': ['ATCATCGAATGGA']}) rrcsBtt|j||_||_||_d|j|jf|_d|_d|_dS)Nz&Expected %r (with up to %d mismatches)F) rrlrr match_string maxMismatchesrar`r[)rrr)rHrwrxr szCloseMatch.__init__TcCs|}t|}|t|j}||kr|j}d}g} |j} xtt||||jD]0\}} | \} } | | krP| j|t| | krPPqPW|d}t|||g}|j|d<| |d<||fSt|||j|dS)Nrrroriginal mismatches) rrrrrrr"rra)rr-rrostartrmaxlocrZmatch_stringlocrrZs_msrcmatresultsrwrwrxr s("   zCloseMatch.parseImpl)rr)T)rrrrrrrrwrw)rHrxrl s cs8eZdZdZd fdd Zdd d Zfd d ZZS)r/a Token for matching words composed of allowed character sets. Defined with string containing all allowed initial characters, an optional string containing allowed body characters (if omitted, defaults to the initial character set), and an optional minimum, maximum, and/or exact length. The default value for C{min} is 1 (a minimum value < 1 is not valid); the default values for C{max} and C{exact} are 0, meaning no maximum or exact length restriction. An optional C{excludeChars} parameter can list characters that might be found in the input C{bodyChars} string; useful to define a word of all printables except for one or two characters, for instance. L{srange} is useful for defining custom character set strings for defining C{Word} expressions, using range notation from regular expression character sets. A common mistake is to use C{Word} to match a specific literal string, as in C{Word("Address")}. Remember that C{Word} uses the string argument to define I{sets} of matchable characters. This expression would match "Add", "AAA", "dAred", or any other word made up of the characters 'A', 'd', 'r', 'e', and 's'. To match an exact literal string, use L{Literal} or L{Keyword}. pyparsing includes helper strings for building Words: - L{alphas} - L{nums} - L{alphanums} - L{hexnums} - L{alphas8bit} (alphabetic characters in ASCII range 128-255 - accented, tilded, umlauted, etc.) - L{punc8bit} (non-alphabetic characters in ASCII range 128-255 - currency, symbols, superscripts, diacriticals, etc.) - L{printables} (any non-whitespace character) Example:: # a word composed of digits integer = Word(nums) # equivalent to Word("0123456789") or Word(srange("0-9")) # a word with a leading capital, and zero or more lowercase capital_word = Word(alphas.upper(), alphas.lower()) # hostnames are alphanumeric, with leading alpha, and '-' hostname = Word(alphas, alphanums+'-') # roman numeral (not a strict parser, accepts invalid mix of characters) roman = Word("IVXLCDM") # any string of non-whitespace characters, except for ',' csv_value = Word(printables, excludeChars=",") NrrrFc stt|jrFdjfdd|D}|rFdjfdd|D}||_t||_|rl||_t||_n||_t||_|dk|_ |dkrt d||_ |dkr||_ nt |_ |dkr||_ ||_ t||_d|j|_d |_||_d |j|jkr|dkr|dkr|dkr|j|jkr8d t|j|_nHt|jdkrfd tj|jt|jf|_nd t|jt|jf|_|jrd|jd|_ytj|j|_Wntk rd|_YnXdS)Nrc3s|]}|kr|VqdS)Nrw)rr) excludeCharsrwrxr7 sz Word.__init__..c3s|]}|kr|VqdS)Nrw)rr)rrwrxr9 srrrzZcannot specify a minimum length < 1; use Optional(Word()) if zero-length word is permittedz Expected Frz[%s]+z%s[%s]*z [%s][%s]*z\b)rr/rr initCharsOrigr initChars bodyCharsOrig bodyChars maxSpecifiedrminLenmaxLenrrrrar` asKeyword_escapeRegexRangeCharsreStringrrdescapecompilerK)rrrminmaxexactrr)rH)rrxr4 sT      0 z Word.__init__Tc CsD|jr<|jj||}|s(t|||j||j}||jfS|||jkrZt|||j||}|d7}t|}|j}||j }t ||}x ||kr|||kr|d7}qWd} |||j krd} |j r||kr|||krd} |j r|dkr||d|ks||kr|||krd} | r4t|||j|||||fS)NrrFTr)rdrrraendgrouprrrrr rrr) rr-rrorrrZ bodycharsrZthrowExceptionrwrwrxrj s6    4zWord.parseImplc stytt|jStk r"YnX|jdkrndd}|j|jkr^d||j||jf|_nd||j|_|jS)NcSs$t|dkr|dddS|SdS)Nz...)r)rrwrwrx charsAsStr s z Word.__str__..charsAsStrz W:(%s,%s)zW:(%s))rr/rrKrUrr)rr)rHrwrxr s  z Word.__str__)NrrrrFN)T)rrrrrrrrrwrw)rHrxr/ s.6 #csFeZdZdZeejdZd fdd Zd ddZ fd d Z Z S) r'a Token for matching strings that match a given regular expression.

When the expression is known, it is assigned to the C{Forward} variable using the '<<' operator. Note: take care when assigning to C{Forward} not to overlook precedence of operators. Specifically, '|' has a lower precedence than '<<', so that:: fwdExpr << a | b | c will actually be evaluated as:: (fwdExpr << a) | b | c thereby leaving b and c out as parseable alternatives. It is recommended that you explicitly group the values inserted into the C{Forward}:: fwdExpr << (a | b | c) Converting to use the '<<=' operator instead will avoid this problem.

Example:: countedArray(Word(alphas)).parseString('2 ab cd ef') # -> ['ab', 'cd'] # in this parser, the leading integer value is given in binary, # '10' indicating that 2 values are in the array binaryConstant = Word('01').setParseAction(lambda t: int(t[0], 2)) countedArray(Word(alphas), intExpr=binaryConstant).parseString('10 ab cd ef') # -> ['ab', 'cd'] cs.|d}|r ttg|p&tt>gS)Nr)rrrC)rr5rvr) arrayExprr.rwrxcountFieldParseAction_s"z+countedArray..countFieldParseActionNcSs t|dS)Nr)ru)rvrwrwrxrydszcountedArray..ZarrayLenT)rfz(len) z...)rr/rRrrrirxr)r.ZintExprrdrw)rcr.rxr<Ls cCs:g}x0|D](}t|tr(|jt|q |j|q W|S)N)rzrrrr)Lrrrwrwrxrks   rcs6tfdd}|j|ddjdt|S)a* Helper to define an expression that is indirectly defined from the tokens matched in a previous expression, that is, it looks for a 'repeat' of a previous expression.

Parameters: - strs - a string of space-delimited literals, or a collection of string literals - caseless - (default=C{False}) - treat all literals as caseless - useRegex - (default=C{True}) - as an optimization, will generate a Regex object; otherwise, will generate a C{MatchFirst} object (if C{caseless=True}, or if creating a C{Regex} raises an exception) Example:: comp_oper = oneOf("< = > <= >= !=") var = Word(alphas) number = Word(nums) term = var | number comparison_expr = term + comp_oper + term print(comparison_expr.searchString("B = 12 AA=23 B<=AA AA>12")) prints:: [['B', '=', '12'], ['AA', '=', '23'], ['B', '<=', 'AA'], ['AA', '>', '12']] cSs|j|jkS)N)r)rbrwrwrxryszoneOf..cSs|jj|jS)N)rr)rrlrwrwrxryscSs||kS)Nrw)rrlrwrwrxryscSs |j|S)N)r)rrlrwrwrxrysz6Invalid argument to oneOf, expected string or iterablerq)rrrrNrz[%s]css|]}t|VqdS)N)r)rsymrwrwrxrszoneOf..z | |css|]}tj|VqdS)N)rdr )rrmrwrwrxrsz7Exception creating Regex for oneOf, building MatchFirstc3s|]}|VqdS)Nrw)rrm)parseElementClassrwrxrs)rrrzrrrr5rrrrrrrrrr'rirKr) ZstrsrZuseRegexZisequalZmasksZsymbolsrZcurrrrw)rorxrSsL         ((cCsttt||S)a Helper to easily and clearly define a dictionary by specifying the respective patterns for the key and value. Takes care of defining the C{L{Dict}}, C{L{ZeroOrMore}}, and C{L{Group}} tokens in the proper order. The key pattern can include delimiting markers or punctuation, as long as they are suppressed, thereby leaving the significant key text. The value pattern can include named results, so that the C{Dict} results can include named token fields. Example:: text = "shape: SQUARE posn: upper left color: light blue texture: burlap" attr_expr = (label + Suppress(':') + OneOrMore(data_word, stopOn=label).setParseAction(' '.join)) print(OneOrMore(attr_expr).parseString(text).dump()) attr_label = label attr_value = Suppress(':') + OneOrMore(data_word, stopOn=label).setParseAction(' '.join) # similar to Dict, but simpler call format result = dictOf(attr_label, attr_value).parseString(text) print(result.dump()) print(result['shape']) print(result.shape) # object attribute access works too print(result.asDict()) prints:: [['shape', 'SQUARE'], ['posn', 'upper left'], ['color', 'light blue'], ['texture', 'burlap']] - color: light blue - posn: upper left - shape: SQUARE - texture: burlap SQUARE SQUARE {'color': 'light blue', 'shape': 'SQUARE', 'posn': 'upper left', 'texture': 'burlap'} )r r2r)rrrwrwrxrAs!cCs^tjdd}|j}d|_|d||d}|r@dd}ndd}|j||j|_|S) a Helper to return the original, untokenized text for a given expression. Useful to restore the parsed fields of an HTML start tag into the raw tag text itself, or to revert separate tokens with intervening whitespace back to the original matching input text. By default, returns astring containing the original parsed text. If the optional C{asString} argument is passed as C{False}, then the return value is a C{L{ParseResults}} containing any results names that were originally matched, and a single token containing the original matched text from the input string. So if the expression passed to C{L{originalTextFor}} contains expressions with defined results names, you must set C{asString} to C{False} if you want to preserve those results name values. Example:: src = "this is test bold text normal text " for tag in ("b","i"): opener,closer = makeHTMLTags(tag) patt = originalTextFor(opener + SkipTo(closer) + closer) print(patt.searchString(src)[0]) prints:: [' bold text '] ['text'] cSs|S)Nrw)rrrvrwrwrxry8sz!originalTextFor..F_original_start _original_endcSs||j|jS)N)rprq)rr5rvrwrwrxry=scSs&||jd|jdg|dd<dS)Nrprq)r)rr5rvrwrwrx extractText?sz$originalTextFor..extractText)r rrrer])r.ZasStringZ locMarkerZ endlocMarker matchExprrrrwrwrxrg s  cCst|jddS)zp Helper to undo pyparsing's default grouping of And expressions, even if all but one are non-empty. cSs|dS)Nrrw)rvrwrwrxryJszungroup..)r-r)r.rwrwrxrhEscCs4tjdd}t|d|d|jjdS)a Helper to decorate a returned token with its starting and ending locations in the input string.

Use C{withAttribute} to qualify a starting tag with a required attribute value, to avoid false matches on common tags such as C{} or C{
}. Call C{withAttribute} with a series of attribute names and values. Specify the list of filter attributes names and values as: - keyword arguments, as in C{(align="right")}, or - as an explicit dict with C{**} operator, when an attribute name is also a Python reserved word, as in C{**{"class":"Customer", "align":"right"}} - a list of name-value tuples, as in ( ("ns1:class", "Customer"), ("ns2:align","right") ) For attribute names with a namespace prefix, you must use the second form. Attribute names are matched insensitive to upper/lower case. If just testing for C{class} (with or without a namespace), use C{L{withClass}}. To verify that the attribute exists, but without specifying a value, pass C{withAttribute.ANY_VALUE} as the value. Example:: html = '''

Operators may be unary or binary, left- or right-associative. Parse actions can also be attached to operator expressions. The generated parser will also recognize the use of parentheses to override operator precedences (see example below). Note: if you define a deep operator list, you may see performance issues when using infixNotation. See L{ParserElement.enablePackrat} for a mechanism to potentially improve your parser performance. Parameters: - baseExpr - expression representing the most basic element for the nested - opList - list of tuples, one for each operator precedence level in the expression grammar; each tuple is of the form (opExpr, numTerms, rightLeftAssoc, parseAction), where: - opExpr is the pyparsing expression for the operator; may also be a string, which will be converted to a Literal; if numTerms is 3, opExpr is a tuple of two expressions, for the two operators separating the 3 terms - numTerms is the number of terms for this operator (must be 1, 2, or 3) - rightLeftAssoc is the indicator whether the operator is right or left associative, using the pyparsing-defined constants C{opAssoc.RIGHT} and C{opAssoc.LEFT}. - parseAction is the parse action to be associated with expressions matching this operator expression (the parse action tuple member may be omitted) - lpar - expression for matching left-parentheses (default=C{Suppress('(')}) - rpar - expression for matching right-parentheses (default=C{Suppress(')')}) Example:: # simple example of four-function arithmetic with ints and variable names integer = pyparsing_common.signed_integer varname = pyparsing_common.identifier arith_expr = infixNotation(integer | varname, [ ('-', 1, opAssoc.RIGHT), (oneOf('* /'), 2, opAssoc.LEFT), (oneOf('+ -'), 2, opAssoc.LEFT), ]) arith_expr.runTests(''' 5+3*6 (5+3)*6 -2--11 ''', fullDump=False) prints:: 5+3*6 [[5, '+', [3, '*', 6]]] (5+3)*6 [[[5, '+', 3], '*', 6]] -2--11 [[['-', 2], '-', ['-', 11]]] Nrroz%s termz %s%s termrqz@if numterms=3, opExpr must be a tuple or list of two expressionsrrz6operator must be unary (1), binary (2), or ternary (3)z2operator must indicate right or left associativity)N)rrrrrirTLEFTrrrRIGHTrzrr.r)ZbaseExprZopListZlparZrparrZlastExprrZoperDefZopExprZarityZrightLeftAssocr}ZtermNameZopExpr1ZopExpr2ZthisExprrsrwrwrxrisR;    &       &   z4"(?:[^"\n\r\\]|(?:"")|(?:\\(?:[^x]|x[0-9a-fA-F]+)))*"z string enclosed in double quotesz4'(?:[^'\n\r\\]|(?:'')|(?:\\(?:[^x]|x[0-9a-fA-F]+)))*'z string enclosed in single quotesz*quotedString using single or double quotesuzunicode string literalcCs||krtd|dkr(t|to,t|tr t|dkrt|dkr|dk rtt|t||tjddj dd}n$t j t||tjj dd}nx|dk rtt|t |t |ttjddj dd}n4ttt |t |ttjddj d d}ntd t }|dk rb|tt|t||B|Bt|K}n$|tt|t||Bt|K}|jd ||f|S) a~ Helper method for defining nested lists enclosed in opening and closing delimiters ("(" and ")" are the default). Parameters: - opener - opening character for a nested list (default=C{"("}); can also be a pyparsing expression - closer - closing character for a nested list (default=C{")"}); can also be a pyparsing expression - content - expression for items within the nested lists (default=C{None}) - ignoreExpr - expression for ignoring opening and closing delimiters (default=C{quotedString}) If an expression is not provided for the content argument, the nested expression will capture all whitespace-delimited content between delimiters as a list of separate values. Use the C{ignoreExpr} argument to define expressions that may contain opening or closing characters that should not be treated as opening or closing characters for nesting, such as quotedString or a comment expression. Specify multiple expressions using an C{L{Or}} or C{L{MatchFirst}}. The default is L{quotedString}, but if no expressions are to be ignored, then pass C{None} for this argument.

pyparsing module - Classes and methods to define and execute parsing grammars

The pyparsing module is an alternative approach to creating and executing simple grammars,
vs. the traditional lex/yacc approach, or the use of regular expressions.  With pyparsing, you
don't need to learn a new syntax for defining grammars or matching expressions - the parsing module
provides a library of classes that you use to construct the grammar directly in Python.

Here is a program to parse "Hello, World!" (or any greeting of the form 
C{", !"}), built up using L{Word}, L{Literal}, and L{And} elements 
(L{'+'} operator gives L{And} expressions, strings are auto-converted to
L{Literal} expressions)::

    from pyparsing import Word, alphas

    # define grammar of a greeting
    greet = Word(alphas) + "," + Word(alphas) + "!"

    hello = "Hello, World!"
    print (hello, "->", greet.parseString(hello))

The program outputs the following::

    Hello, World! -> ['Hello', ',', 'World', '!']

The Python representation of the grammar is quite readable, owing to the self-explanatory
class names, and the use of '+', '|' and '^' operators.

The L{ParseResults} object returned from L{ParserElement.parseString} can be accessed as a nested list, a dictionary, or an
object with named attributes.

The pyparsing module handles some of the problems that are typically vexing when writing text parsers:
 - extra or missing whitespace (the above program will also handle "Hello,World!", "Hello  ,  World  !", etc.)
 - quoted strings
 - embedded comments

           Repeated parse attempts at the same string location (which happens
           often in many complex grammars) can immediately return a cached value,
           instead of re-executing parsing/validating code.  Memoizing is done of
           both valid results and parsing exceptions.
           
           Parameters:
            - cache_size_limit - (default=C{128}) - if an integer value is provided
              will limit the size of the packrat cache; if None is passed, then
              the cache size will be unbounded; if 0 is passed, the cache will
              be effectively disabled.
            
           This speedup may break existing programs that use parse actions that
           have side-effects.  For this reason, packrat parsing is disabled when
           you first import pyparsing.  To activate the packrat feature, your
           program must call the class method C{ParserElement.enablePackrat()}.  If
           your program uses C{psyco} to "compile as you go", you must call
           C{enablePackrat} before calling C{psyco.full()}.  If you do not do this,
           Python will crash.  For best results, call C{enablePackrat()} immediately
           after importing pyparsing.

        If the input string contains tabs and

         - calling C{parseWithTabs} on your grammar before calling C{parseString}

class Word(Token):
    """
    Token for matching words composed of allowed character sets.
    Defined with string containing all allowed initial characters,
    an optional string containing allowed body characters (if omitted,
    defaults to the initial character set), and an optional minimum,
    maximum, and/or exact length.  The default value for C{min} is 1 (a
    minimum value < 1 is not valid); the default values for C{max} and C{exact}
    are 0, meaning no maximum or exact length restriction. An optional
    C{excludeChars} parameter can list characters that might be found in 
    the input C{bodyChars} string; useful to define a word of all printables
    except for one or two characters, for instance.
    
    L{srange} is useful for defining custom character set strings for defining 
    C{Word} expressions, using range notation from regular expression character sets.
    
    A common mistake is to use C{Word} to match a specific literal string, as in 
    C{Word("Address")}. Remember that C{Word} uses the string argument to define
    I{sets} of matchable characters. This expression would match "Add", "AAA",
    "dAred", or any other word made up of the characters 'A', 'd', 'r', 'e', and 's'.
    To match an exact literal string, use L{Literal} or L{Keyword}.

    pyparsing includes helper strings for building Words:
     - L{alphas}
     - L{nums}
     - L{alphanums}
     - L{hexnums}
     - L{alphas8bit} (alphabetic characters in ASCII range 128-255 - accented, tilded, umlauted, etc.)
     - L{punc8bit} (non-alphabetic characters in ASCII range 128-255 - currency, symbols, superscripts, diacriticals, etc.)
     - L{printables} (any non-whitespace character)

    Example::
        # a word composed of digits
        integer = Word(nums) # equivalent to Word("0123456789") or Word(srange("0-9"))
        
        # a word with a leading capital, and zero or more lowercase
        capital_word = Word(alphas.upper(), alphas.lower())

        # hostnames are alphanumeric, with leading alpha, and '-'
        hostname = Word(alphas, alphanums+'-')

    Token for matching strings that are delimited by quoting characters.
    
    Defined with the following parameters:
        - quoteChar - string of one or more characters defining the quote delimiting string
        - escChar - character to escape quotes, typically backslash (default=C{None})
        - escQuote - special quote sequence to escape an embedded quote string (such as SQL's "" to escape an embedded ") (default=C{None})
        - multiline - boolean indicating whether quotes can span multiple lines (default=C{False})
        - unquoteResults - boolean indicating whether the matched text should be unquoted (default=C{True})
        - endQuoteChar - string of one or more characters defining the end of the quote delimited string (default=C{None} => same as quoteChar)
        - convertWhitespaceEscapes - convert escaped whitespace (C{'\t'}, C{'\n'}, etc.) to actual whitespace (default=C{True})

    """
    Helper method for constructing grammars of expressions made up of
    operators working in a precedence hierarchy.  Operators may be unary or
    binary, left- or right-associative.  Parse actions can also be attached
    to operator expressions. The generated parser will also recognize the use 
    of parentheses to override operator precedences (see example below).
    
    Note: if you define a deep operator list, you may see performance issues
    when using infixNotation. See L{ParserElement.enablePackrat} for a
    mechanism to potentially improve your parser performance.

    Parameters:
     - baseExpr - expression representing the most basic element for the nested
     - opList - list of tuples, one for each operator precedence level in the
      expression grammar; each tuple is of the form
      (opExpr, numTerms, rightLeftAssoc, parseAction), where:
       - opExpr is the pyparsing expression for the operator;
          may also be a string, which will be converted to a Literal;
          if numTerms is 3, opExpr is a tuple of two expressions, for the
          two operators separating the 3 terms
       - numTerms is the number of terms for this operator (must
          be 1, 2, or 3)
       - rightLeftAssoc is the indicator whether the operator is
          right or left associative, using the pyparsing-defined
          constants C{opAssoc.RIGHT} and C{opAssoc.LEFT}.
       - parseAction is the parse action to be associated with
          expressions matching this operator expression (the
          parse action tuple member may be omitted)
     - lpar - expression for matching left-parentheses (default=C{Suppress('(')})
     - rpar - expression for matching right-parentheses (default=C{Suppress(')')})

build_clibav
    Override the default build_clib behaviour to do the following:

    1. Implement a rudimentary timestamp-based dependency system
       so 'compile()' doesn't run every time.
    2. Add more keys to the 'build_info' dictionary:
        * obj_deps - specify dependencies for each object compiled.
                     this should be a dictionary mapping a key
                     with the source filename to a list of
                     dependencies. Use an empty string for global
                     dependencies.
        * cflags   - specify a list of additional flags to pass to
                     the compiler.

        Because this distribution was installed --multi-version, before you can
        import modules from this package in an application, you will need to
        'import pkg_resources' and then use a 'require()' call similar to one of
        these examples, in order to select the desired version:

            pkg_resources.require("%(name)s")  # latest installed version
            pkg_resources.require("%(name)s==%(version)s")  # this exact version
            pkg_resources.require("%(name)s>=%(version)s")  # this version or higher
        z
        Note also that the installation directory must be on sys.path at runtime for
        this to work.  (e.g. by being the application's script directory, by being on
        PYTHONPATH, or by being added to sys.path by your code.)

        bad install directory or PYTHONPATH

        You are attempting to install a package to a directory that is not
        on PYTHONPATH and which Python does not read ".pth" files from.  The
        installation directory you specified (via --install-dir, --prefix, or
        the distutils default setting) was:

            %s

        and your PYTHONPATH environment variable currently contains:

            %r

        Here are some of your options for correcting the problem:

        * You can choose a different installation directory, i.e., one that is
          on PYTHONPATH or supports .pth files

        * You can add the installation directory to the PYTHONPATH environment
          variable.  (It must then also be on PYTHONPATH whenever you run
          Python and want to use the package(s) you are installing.)

        * You can set up the installation directory to support ".pth" files by
          using one of the approaches described here:

    Fix any globally cached `dist_path` related data

    `dist_path` should be a path of a newly installed egg distribution (zipped
    or unzipped).

    sys.path_importer_cache contains finder objects that have been cached when
    importing data from the original distribution. Any such finders need to be
    cleared since the replacement distribution might be packaged differently,
    e.g. a zipped egg distribution might get replaced with an unzipped egg
    folder or vice versa. Having the old finders cached may then cause Python
    to attempt loading modules from the replacement distribution using an
    incorrect loader.

    zipimport.zipimporter objects are Python loaders charged with importing
    data packaged inside zip archives. If stale loaders referencing the
    original distribution, are left behind, they can fail to load modules from
    the replacement distribution. E.g. if an old zipimport.zipimporter instance
    is used to load data from a new zipped egg archive, it may cause the
    operation to attempt to locate the requested data in the wrong location -
    one indicated by the original distribution's zip archive directory
    information. Such an operation may then fail outright, e.g. report having
    read a 'bad local file header', or even worse, it may fail silently &
    return invalid data.

    zipimport._zip_directory_cache contains cached zip archive directory
    information for all existing zipimport.zipimporter instances and all such
    instances connected to the same archive share the same cached directory
    information.

    If asked, and the underlying Python implementation allows it, we can fix
    all existing zipimport.zipimporter instances instead of having to track
    them down and remove them one by one, by updating their shared cached zip
    archive directory information. This, of course, assumes that the
    replacement distribution is packaged as a zipped egg.

    If not asked to fix existing zipimport.zipimporter instances, we still do
    our best to clear any remaining zipimport.zipimporter related cached data
    that might somehow later get used when attempting to load data from the new
    distribution and thus cause such load operations to fail. Note that when
    tracking down such remaining stale data, we can not catch every conceivable
    usage from here, and we clear only those that we know of and have found to
    cause problems if left alive. Any remaining caches should be updated by
    whomever is in charge of maintaining them, i.e. they should be ready to
    handle us replacing their zip archives with new distributions at runtime.

    Update zipimporter cache data for a given normalized path.

    Any sub-path entries are processed as well, i.e. those corresponding to zip
    archives embedded in other zip archives.

    Given updater is a callable taking a cache entry key and the original entry
    (after already removing the entry from the cache), and expected to update
    the entry and possibly return a new one to be inserted in its place.
    Returning None indicates that the entry should not be replaced with a new
    one. If no updater is given, the cache entries are simply removed without
    any additional processing, the same as if the updater simply returned None.

        Because this distribution was installed --multi-version, before you can
        import modules from this package in an application, you will need to
        'import pkg_resources' and then use a 'require()' call similar to one of
        these examples, in order to select the desired version:

            pkg_resources.require("%(name)s")  # latest installed version
            pkg_resources.require("%(name)s==%(version)s")  # this exact version
            pkg_resources.require("%(name)s>=%(version)s")  # this version or higher
        z
        Note also that the installation directory must be on sys.path at runtime for
        this to work.  (e.g. by being the application's script directory, by being on
        PYTHONPATH, or by being added to sys.path by your code.)

        bad install directory or PYTHONPATH

        You are attempting to install a package to a directory that is not
        on PYTHONPATH and which Python does not read ".pth" files from.  The
        installation directory you specified (via --install-dir, --prefix, or
        the distutils default setting) was:

            %s

        and your PYTHONPATH environment variable currently contains:

            %r

        Here are some of your options for correcting the problem:

        * You can choose a different installation directory, i.e., one that is
          on PYTHONPATH or supports .pth files

        * You can add the installation directory to the PYTHONPATH environment
          variable.  (It must then also be on PYTHONPATH whenever you run
          Python and want to use the package(s) you are installing.)

        * You can set up the installation directory to support ".pth" files by
          using one of the approaches described here:

          https://setuptools.readthedocs.io/en/latest/easy_install.html#custom-installation-locations

    Fix any globally cached `dist_path` related data

    `dist_path` should be a path of a newly installed egg distribution (zipped
    or unzipped).

    sys.path_importer_cache contains finder objects that have been cached when
    importing data from the original distribution. Any such finders need to be
    cleared since the replacement distribution might be packaged differently,
    e.g. a zipped egg distribution might get replaced with an unzipped egg
    folder or vice versa. Having the old finders cached may then cause Python
    to attempt loading modules from the replacement distribution using an
    incorrect loader.

    zipimport.zipimporter objects are Python loaders charged with importing
    data packaged inside zip archives. If stale loaders referencing the
    original distribution, are left behind, they can fail to load modules from
    the replacement distribution. E.g. if an old zipimport.zipimporter instance
    is used to load data from a new zipped egg archive, it may cause the
    operation to attempt to locate the requested data in the wrong location -
    one indicated by the original distribution's zip archive directory
    information. Such an operation may then fail outright, e.g. report having
    read a 'bad local file header', or even worse, it may fail silently &
    return invalid data.

    zipimport._zip_directory_cache contains cached zip archive directory
    information for all existing zipimport.zipimporter instances and all such
    instances connected to the same archive share the same cached directory
    information.

    If asked, and the underlying Python implementation allows it, we can fix
    all existing zipimport.zipimporter instances instead of having to track
    them down and remove them one by one, by updating their shared cached zip
    archive directory information. This, of course, assumes that the
    replacement distribution is packaged as a zipped egg.

    If not asked to fix existing zipimport.zipimporter instances, we still do
    our best to clear any remaining zipimport.zipimporter related cached data
    that might somehow later get used when attempting to load data from the new
    distribution and thus cause such load operations to fail. Note that when
    tracking down such remaining stale data, we can not catch every conceivable
    usage from here, and we clear only those that we know of and have found to
    cause problems if left alive. Any remaining caches should be updated by
    whomever is in charge of maintaining them, i.e. they should be ready to
    handle us replacing their zip archives with new distributions at runtime.

    Update zipimporter cache data for a given normalized path.

    Any sub-path entries are processed as well, i.e. those corresponding to zip
    archives embedded in other zip archives.

    Given updater is a callable taking a cache entry key and the original entry
    (after already removing the entry from the cache), and expected to update
    the entry and possibly return a new one to be inserted in its place.
    Returning None indicates that the entry should not be replaced with a new
    one. If no updater is given, the cache entries are simply removed without
    any additional processing, the same as if the updater simply returned None.

build_clibav
    Override the default build_clib behaviour to do the following:

    1. Implement a rudimentary timestamp-based dependency system
       so 'compile()' doesn't run every time.
    2. Add more keys to the 'build_info' dictionary:
        * obj_deps - specify dependencies for each object compiled.
                     this should be a dictionary mapping a key
                     with the source filename to a list of
                     dependencies. Use an empty string for global
                     dependencies.
        * cflags   - specify a list of additional flags to pass to
                     the compiler.

    The data files are specified via a 'package_data' argument to 'setup()'.

        bad install directory or PYTHONPATH

        You are attempting to install a package to a directory that is not
        on PYTHONPATH and which Python does not read ".pth" files from.  The
        installation directory you specified (via --install-dir, --prefix, or
        the distutils default setting) was:

            %s

        and your PYTHONPATH environment variable currently contains:

            %r

        Here are some of your options for correcting the problem:

        * You can choose a different installation directory, i.e., one that is
          on PYTHONPATH or supports .pth files

        * You can add the installation directory to the PYTHONPATH environment
          variable.  (It must then also be on PYTHONPATH whenever you run
          Python and want to use the package(s) you are installing.)

        * You can set up the installation directory to support ".pth" files by
          using one of the approaches described here:

    Fix any globally cached `dist_path` related data

    `dist_path` should be a path of a newly installed egg distribution (zipped
    or unzipped).

    sys.path_importer_cache contains finder objects that have been cached when
    importing data from the original distribution. Any such finders need to be
    cleared since the replacement distribution might be packaged differently,
    e.g. a zipped egg distribution might get replaced with an unzipped egg
    folder or vice versa. Having the old finders cached may then cause Python
    to attempt loading modules from the replacement distribution using an
    incorrect loader.

    zipimport.zipimporter objects are Python loaders charged with importing
    data packaged inside zip archives. If stale loaders referencing the
    original distribution, are left behind, they can fail to load modules from
    the replacement distribution. E.g. if an old zipimport.zipimporter instance
    is used to load data from a new zipped egg archive, it may cause the
    operation to attempt to locate the requested data in the wrong location -
    one indicated by the original distribution's zip archive directory
    information. Such an operation may then fail outright, e.g. report having
    read a 'bad local file header', or even worse, it may fail silently &
    return invalid data.

    zipimport._zip_directory_cache contains cached zip archive directory
    information for all existing zipimport.zipimporter instances and all such
    instances connected to the same archive share the same cached directory
    information.

    If asked, and the underlying Python implementation allows it, we can fix
    all existing zipimport.zipimporter instances instead of having to track
    them down and remove them one by one, by updating their shared cached zip
    archive directory information. This, of course, assumes that the
    replacement distribution is packaged as a zipped egg.

    If not asked to fix existing zipimport.zipimporter instances, we still do
    our best to clear any remaining zipimport.zipimporter related cached data
    that might somehow later get used when attempting to load data from the new
    distribution and thus cause such load operations to fail. Note that when
    tracking down such remaining stale data, we can not catch every conceivable
    usage from here, and we clear only those that we know of and have found to
    cause problems if left alive. Any remaining caches should be updated by
    whomever is in charge of maintaining them, i.e. they should be ready to
    handle us replacing their zip archives with new distributions at runtime.

build_meta.pynu["""A PEP 517 interface to setuptools

Previously, when a user or a command line tool (let's call it a "frontend")
needed to make a request of setuptools to take a certain action, for
example, generating a list of installation requirements, the frontend would
would call "setup.py egg_info" or "setup.py bdist_wheel" on the command line.

PEP 517 defines a different method of interfacing with setuptools. Rather
than calling "setup.py" directly, the frontend should:

  1. Set the current directory to the directory with a setup.py file
  2. Import this module into a safe python interpreter (one in which
     setuptools can potentially set global variables or crash hard).
  3. Call one of the functions defined in PEP 517.

What each function does is defined in PEP 517. However, here is a "casual"
definition of the functions (this definition should not be relied on for
bug reports or API stability):

  - `build_wheel`: build a wheel in the folder and return the basename
  - `get_requires_for_build_wheel`: get the `setup_requires` to build
  - `prepare_metadata_for_build_wheel`: get the `install_requires`
  - `build_sdist`: build an sdist in the folder and return the basename
  - `get_requires_for_build_sdist`: get the `setup_requires` to build

Again, this is not a formal definition! Just a "taste" of the module.

class Distribution(Distribution_parse_config_files, _Distribution):
    """Distribution with support for features, tests, and package data

    This is an enhanced version of 'distutils.dist.Distribution' that
    effectively adds the following new optional keyword arguments to 'setup()':

     'install_requires' -- a string or sequence of strings specifying project
        versions that the distribution requires when installed, in the format
        used by 'pkg_resources.require()'.  They will be installed
        automatically when the package is installed.  If you wish to use
        packages that are not available in PyPI, or want to give your users an
        alternate download location, you can add a 'find_links' option to the
        '[easy_install]' section of your project's 'setup.cfg' file, and then
        setuptools will scan the listed web pages for links that satisfy the
        requirements.

     'extras_require' -- a dictionary mapping names of optional "extras" to the
        additional requirement(s) that using those extras incurs. For example,
        this::

            extras_require = dict(reST = ["docutils>=0.3", "reSTedit"])

        indicates that the distribution can optionally provide an extra
        capability called "reST", but it can only be used if docutils and
        reSTedit are installed.  If the user installs your package using
        EasyInstall and requests one of your extras, the corresponding
        additional requirements will be installed if needed.

     'features' **deprecated** -- a dictionary mapping option names to
        'setuptools.Feature'
        objects.  Features are a portion of the distribution that can be
        included or excluded based on user options, inter-feature dependencies,
        and availability on the current system.  Excluded features are omitted
        from all setup commands, including source and binary distributions, so
        you can create multiple distributions from the same source tree.
        Feature names should be valid Python identifiers, except that they may
        contain the '-' (minus) sign.  Features can be included or excluded
        via the command line options '--with-X' and '--without-X', where 'X' is
        the name of the feature.  Whether a feature is included by default, and
        whether you are allowed to control this from the command line, is
        determined by the Feature object.  See the 'Feature' class for more
        information.

     'test_suite' -- the name of a test suite to run for the 'test' command.
        If the user runs 'python setup.py test', the package will be installed,
        and the named test suite will be run.  The format is the same as
        would be used on a 'unittest.py' command line.  That is, it is the
        dotted name of an object to import and call to generate a test suite.

     'package_data' -- a dictionary mapping package names to lists of filenames
        or globs to use to find data files contained in the named packages.
        If the dictionary has filenames or globs listed under '""' (the empty
        string), those names will be searched for in every package, in addition
        to any names for the specific package.  Data files found using these
        names/globs will be installed along with the package, in the same
        location as the package.  Note that globs are allowed to reference
        the contents of non-package subdirectories, as long as you use '/' as
        a path separator.  (Globs are automatically converted to
        platform-specific paths at runtime.)

    In addition to these new keywords, this class also has several new methods
    for manipulating the distribution's contents.  For example, the 'include()'
    and 'exclude()' methods can be thought of as in-place add and subtract
    commands that add or remove packages, modules, extensions, and so on from
    the distribution.  They are used by the feature subsystem to configure the
    distribution for the included and excluded features.

    **deprecated** -- The `Feature` facility was never completely implemented
    or supported, `has reported issues
    `_ and will be removed in
    a future version.

    A subset of the distribution that can be excluded if unneeded/wanted

    Features are created using these keyword arguments:

      'description' -- a short, human readable description of the feature, to
         be used in error messages, and option help messages.

      'standard' -- if true, the feature is included by default if it is
         available on the current system.  Otherwise, the feature is only
         included if requested via a command line '--with-X' option, or if
         another included feature requires it.  The default setting is 'False'.

      'available' -- if true, the feature is available for installation on the
         current system.  The default setting is 'True'.

      'optional' -- if true, the feature's inclusion can be controlled from the
         command line, using the '--with-X' or '--without-X' options.  If
         false, the feature's inclusion status is determined automatically,
         based on 'availabile', 'standard', and whether any other feature
         requires it.  The default setting is 'True'.

      'require_features' -- a string or sequence of strings naming features
         that should also be included if this feature is included.  Defaults to
         empty list.  May also contain 'Require' objects that should be
         added/removed from the distribution.

      'remove' -- a string or list of strings naming packages to be removed
         from the distribution if this feature is *not* included.  If the
         feature *is* included, this argument is ignored.  This argument exists
         to support removing features that "crosscut" a distribution, such as
         defining a 'tests' feature that removes all the 'tests' subpackages
         provided by other features.  The default for this argument is an empty
         list.  (Note: the named package(s) or modules must exist in the base
         distribution when the 'setup()' function is initially called.)

      other keywords -- any other keyword arguments are saved, and passed to
         the distribution's 'include()' and 'exclude()' methods when the
         feature is included or excluded, respectively.  So, for example, you
         could pass 'packages=["a","b"]' to cause packages 'a' and 'b' to be
         added or removed from the distribution as appropriate.

    A feature must include at least one 'requires', 'remove', or other
    keyword argument.  Otherwise, it can't affect the distribution in any way.
    Note also that you can subclass 'Feature' to create your own specialized
    feature types that modify the distribution in other ways when included or
    excluded.  See the docstrings for the various methods here for more detail.
    Aside from the methods, the only feature attributes that distributions look
    at are 'description' and 'optional'.

    Generate a list of all Python packages found within a directory
    t.t*cCs7t|jt||jdd||j|S(s	Return a list all Python packages found within directory 'where'

        'where' is the root directory which will be searched for packages.  It
        should be supplied as a "cross-platform" (i.e. URL-style) path; it will
        be converted to the appropriate local path syntax.

        'exclude' is a sequence of package names to exclude; '*' can be used
        as a wildcard in the names, such that 'foo.*' will exclude all
        subpackages of 'foo' (but not 'foo' itself).

        'include' is a sequence of package names to include.  If it's
        specified, only the named packages will be included.  If it's not
        specified, all found packages will be included.  'include' can contain
        shell style wildcard patterns just like 'exclude'.

pyparsing module - Classes and methods to define and execute parsing grammars

The pyparsing module is an alternative approach to creating and executing simple grammars,
vs. the traditional lex/yacc approach, or the use of regular expressions.  With pyparsing, you
don't need to learn a new syntax for defining grammars or matching expressions - the parsing module
provides a library of classes that you use to construct the grammar directly in Python.

Here is a program to parse "Hello, World!" (or any greeting of the form 
C{", !"}), built up using L{Word}, L{Literal}, and L{And} elements 
(L{'+'} operator gives L{And} expressions, strings are auto-converted to
L{Literal} expressions)::

    from pyparsing import Word, alphas

    # define grammar of a greeting
    greet = Word(alphas) + "," + Word(alphas) + "!"

    hello = "Hello, World!"
    print (hello, "->", greet.parseString(hello))

The program outputs the following::

    Hello, World! -> ['Hello', ',', 'World', '!']

The Python representation of the grammar is quite readable, owing to the self-explanatory
class names, and the use of '+', '|' and '^' operators.

The L{ParseResults} object returned from L{ParserElement.parseString} can be accessed as a nested list, a dictionary, or an
object with named attributes.

The pyparsing module handles some of the problems that are typically vexing when writing text parsers:
 - extra or missing whitespace (the above program will also handle "Hello,World!", "Hello  ,  World  !", etc.)
 - quoted strings
 - embedded comments

        Removes and returns item at specified index (default=C{last}).
        Supports both C{list} and C{dict} semantics for C{pop()}. If passed no

        non-integer argument (most likely a string), it will use C{dict}

        this is so that the client can define a basic element, such as an

        Define action to perform when successfully matching parse element definition.
        Parse action fn is a callable method with 0-3 arguments, called as C{fn(s,loc,toks)},
        C{fn(loc,toks)}, C{fn(toks)}, or just C{fn()}, where:
         - s   = the original string being parsed (see note below)
         - loc = the location of the matching substring
         - toks = a list of the matched tokens, packaged as a C{L{ParseResults}} object
        If the functions in fns modify the tokens, they can return them as the return
        value from fn, and the modified list of tokens will replace the original.
        Otherwise, fn does not need to return any value.

        Optional keyword arguments:
         - callDuringTry = (default=C{False}) indicate if parse action should be run during lookaheads and alternate testing

        Note: the default parsing behavior is to expand tabs in the input string
        before starting the parsing process.  See L{I{parseString}} for more information
        on parsing strings containing C{}s, and suggested methods to maintain a
        consistent view of the parsed string, the parse location, and line and column
        positions within the parsed string.
        
        Example::
            integer = Word(nums)
            date_str = integer + '/' + integer + '/' + integer

            date_str.parseString("1999/12/31")  # -> ['1999', '/', '12', '/', '31']

            # use parse action to convert to ints at parse time
            integer = Word(nums).setParseAction(lambda toks: int(toks[0]))
            date_str = integer + '/' + integer + '/' + integer

            # note that integer fields are now ints, not strings

        Extension to C{L{scanString}}, to modify matching text with modified tokens that may
        be returned from a parse action.  To use C{transformString}, define a grammar and
        attach a parse action to it that modifies the returned token list.
        Invoking C{transformString()} on a target string will then scan for matches,
        and replace the matched text patterns according to the logic in the parse
        action.  C{transformString()} returns the resulting transformed string.
        
        Example::

        The output shown is that produced by the default debug actions - custom debug actions can be
        specified using L{setDebugActions}. Prior to attempting
        to match the C{wd} expression, the debugging message C{"Match  at loc (,)"}
        is shown. Then if the parse succeeds, a C{"Matched"} message is shown, or an C{"Exception raised"}
        message is shown. Also note the use of L{setName} to assign a human-readable name to the expression,
        which makes debugging and exception messages easier to understand - for instance, the default
        name created for the C{Word} expression without calling C{setName} is C{"W:(ABCD...)"}.

        Execute the parse expression on a series of test strings, showing each
        test, the parsed results or where the parse failed. Quick and easy way to
        run a parse expression against a list of sample strings.
           
        Parameters:
         - tests - a list of separate test strings, or a multiline string of test strings
         - parseAll - (default=C{True}) - flag to pass to C{L{parseString}} when running tests           
         - comment - (default=C{'#'}) - expression for indicating embedded comments in the test 
              string; pass None to disable comment filtering
         - fullDump - (default=C{True}) - dump results as list followed by results names in nested outline;
              if False, only dump nested list
         - printResults - (default=C{True}) prints test output to stdout
         - failureTests - (default=C{False}) indicates if these tests are expected to fail parsing

        Returns: a (success, results) tuple, where success indicates that all tests succeeded
        (or failed if C{failureTests} is True), and the results contain a list of lines of each 
        test's output
        
        Example::
            number_expr = pyparsing_common.number.copy()

            result = number_expr.runTests('''
                # unsigned integer
                100
                # negative integer

                ''')
            print("Success" if result[0] else "Failed!")

            Success

        Each test string must be on a single line. If you want to test a string that spans multiple
        lines, create a test like this::

            expr.runTest(r"this is a test\n of strings that spans \n 3 lines")
        
        (Note that this is a raw string literal, you must include the leading 'r'.)

    Token to exactly match a specified string as a keyword, that is, it must be
    immediately followed by a non-keyword character.  Compare with C{L{Literal}}:
     - C{Literal("if")} will match the leading C{'if'} in C{'ifAndOnlyIf'}.
     - C{Keyword("if")} will not; it will only match the leading C{'if'} in C{'if x=1'}, or C{'if(y==2)'}
    Accepts two optional constructor arguments in addition to the keyword string:
     - C{identChars} is a string of characters that would be valid identifier characters,
          defaulting to all alphanumerics + "_" and "$"
     - C{caseless} allows case-insensitive matching, default is C{False}.

    A variation on L{Literal} which matches "close" matches, that is, 
    strings with at most 'n' mismatching characters. C{CloseMatch} takes parameters:
     - C{match_string} - string to be matched
     - C{maxMismatches} - (C{default=1}) maximum number of mismatches allowed to count as a match
    
    The results from a successful parse will contain the matched text from the input string and the following named results:
     - C{mismatches} - a list of the positions within the match_string where mismatches were found
     - C{original} - the original match_string used to compare against the input string
    
    If C{mismatches} is an empty list, then the match was an exact match.
    
    Example::
        patt = CloseMatch("ATCATCGAATGGA")
        patt.parseString("ATCATCGAAXGGA") # -> (['ATCATCGAAXGGA'], {'mismatches': [[9]], 'original': ['ATCATCGAATGGA']})
        patt.parseString("ATCAXCGAAXGGA") # -> Exception: Expected 'ATCATCGAATGGA' (with up to 1 mismatches) (at char 0), (line:1, col:1)

        # exact match
        patt.parseString("ATCATCGAATGGA") # -> (['ATCATCGAATGGA'], {'mismatches': [[]], 'original': ['ATCATCGAATGGA']})

        # close match allowing up to 2 mismatches
        patt = CloseMatch("ATCATCGAATGGA", maxMismatches=2)
        patt.parseString("ATCAXCGAAXGGA") # -> (['ATCAXCGAAXGGA'], {'mismatches': [[4, 9]], 'original': ['ATCATCGAATGGA']})

    Token for matching words composed of allowed character sets.
    Defined with string containing all allowed initial characters,
    an optional string containing allowed body characters (if omitted,
    defaults to the initial character set), and an optional minimum,
    maximum, and/or exact length.  The default value for C{min} is 1 (a
    minimum value < 1 is not valid); the default values for C{max} and C{exact}
    are 0, meaning no maximum or exact length restriction. An optional
    C{excludeChars} parameter can list characters that might be found in 
    the input C{bodyChars} string; useful to define a word of all printables
    except for one or two characters, for instance.
    
    L{srange} is useful for defining custom character set strings for defining 
    C{Word} expressions, using range notation from regular expression character sets.
    
    A common mistake is to use C{Word} to match a specific literal string, as in 
    C{Word("Address")}. Remember that C{Word} uses the string argument to define
    I{sets} of matchable characters. This expression would match "Add", "AAA",
    "dAred", or any other word made up of the characters 'A', 'd', 'r', 'e', and 's'.
    To match an exact literal string, use L{Literal} or L{Keyword}.

    pyparsing includes helper strings for building Words:
     - L{alphas}
     - L{nums}
     - L{alphanums}
     - L{hexnums}
     - L{alphas8bit} (alphabetic characters in ASCII range 128-255 - accented, tilded, umlauted, etc.)
     - L{punc8bit} (non-alphabetic characters in ASCII range 128-255 - currency, symbols, superscripts, diacriticals, etc.)
     - L{printables} (any non-whitespace character)

    Example::
        # a word composed of digits
        integer = Word(nums) # equivalent to Word("0123456789") or Word(srange("0-9"))
        
        # a word with a leading capital, and zero or more lowercase
        capital_word = Word(alphas.upper(), alphas.lower())

        # hostnames are alphanumeric, with leading alpha, and '-'
        hostname = Word(alphas, alphanums+'-')
        
        # roman numeral (not a strict parser, accepts invalid mix of characters)
        roman = Word("IVXLCDM")
        
        # any string of non-whitespace characters, except for ','
        csv_value = Word(printables, excludeChars=",")

    Token for matching strings that are delimited by quoting characters.
    
    Defined with the following parameters:
        - quoteChar - string of one or more characters defining the quote delimiting string
        - escChar - character to escape quotes, typically backslash (default=C{None})
        - escQuote - special quote sequence to escape an embedded quote string (such as SQL's "" to escape an embedded ") (default=C{None})
        - multiline - boolean indicating whether quotes can span multiple lines (default=C{False})
        - unquoteResults - boolean indicating whether the matched text should be unquoted (default=C{True})
        - endQuoteChar - string of one or more characters defining the end of the quote delimited string (default=C{None} => same as quoteChar)
        - convertWhitespaceEscapes - convert escaped whitespace (C{'\t'}, C{'\n'}, etc.) to actual whitespace (default=C{True})

    Example::
        qs = QuotedString('"')
        print(qs.searchString('lsjdf "This is the quote" sldjf'))
        complex_qs = QuotedString('{{', endQuoteChar='}}')

    Helper to quickly define a set of alternative Literals, and makes sure to do
    longest-first testing when there is a conflict, regardless of the input order,
    but returns a C{L{MatchFirst}} for best performance.

    Parameters:
     - strs - a string of space-delimited literals, or a collection of string literals
     - caseless - (default=C{False}) - treat all literals as caseless
     - useRegex - (default=C{True}) - as an optimization, will generate a Regex
          object; otherwise, will generate a C{MatchFirst} object (if C{caseless=True}, or

    Helper to easily and clearly define a dictionary by specifying the respective patterns
    for the key and value.  Takes care of defining the C{L{Dict}}, C{L{ZeroOrMore}}, and C{L{Group}} tokens
    in the proper order.  The key pattern can include delimiting markers or punctuation,
    as long as they are suppressed, thereby leaving the significant key text.  The value
    pattern can include named results, so that the C{Dict} results can include named token
    fields.

    Example::
        text = "shape: SQUARE posn: upper left color: light blue texture: burlap"
        attr_expr = (label + Suppress(':') + OneOrMore(data_word, stopOn=label).setParseAction(' '.join))

    Helper to return the original, untokenized text for a given expression.  Useful to
    restore the parsed fields of an HTML start tag into the raw tag text itself, or to
    revert separate tokens with intervening whitespace back to the original matching
    input text. By default, returns astring containing the original parsed text.  
       
    If the optional C{asString} argument is passed as C{False}, then the return value is a 
    C{L{ParseResults}} containing any results names that were originally matched, and a 
    single token containing the original matched text from the input string.  So if 
    the expression passed to C{L{originalTextFor}} contains expressions with defined
    results names, you must set C{asString} to C{False} if you want to preserve those
    results name values.

    Example::
        src = "this is test  bold text  normal text "
        for tag in ("b","i"):
            opener,closer = makeHTMLTags(tag)

    Helper to create a validating parse action to be used with start tags created
    with C{L{makeXMLTags}} or C{L{makeHTMLTags}}. Use C{withAttribute} to qualify a starting tag
    with a required attribute value, to avoid false matches on common tags such as
    C{} or C{
}.

    Call C{withAttribute} with a series of attribute names and values. Specify the list
    of filter attributes names and values as:
     - keyword arguments, as in C{(align="right")}, or
     - as an explicit dict with C{**} operator, when an attribute name is also a Python
          reserved word, as in C{**{"class":"Customer", "align":"right"}}
     - a list of name-value tuples, as in ( ("ns1:class", "Customer"), ("ns2:align","right") )
    For attribute names with a namespace prefix, you must use the second form.  Attribute
    names are matched insensitive to upper/lower case.
       
    If just testing for C{class} (with or without a namespace), use C{L{withClass}}.

    To verify that the attribute exists, but without specifying a value, pass
    C{withAttribute.ANY_VALUE} as the value.

        html = '''

    Helper method for constructing grammars of expressions made up of
    operators working in a precedence hierarchy.  Operators may be unary or
    binary, left- or right-associative.  Parse actions can also be attached
    to operator expressions. The generated parser will also recognize the use 
    of parentheses to override operator precedences (see example below).
    
    Note: if you define a deep operator list, you may see performance issues
    when using infixNotation. See L{ParserElement.enablePackrat} for a
    mechanism to potentially improve your parser performance.

    Parameters:
     - baseExpr - expression representing the most basic element for the nested
     - opList - list of tuples, one for each operator precedence level in the
      expression grammar; each tuple is of the form
      (opExpr, numTerms, rightLeftAssoc, parseAction), where:
       - opExpr is the pyparsing expression for the operator;
          may also be a string, which will be converted to a Literal;
          if numTerms is 3, opExpr is a tuple of two expressions, for the
          two operators separating the 3 terms
       - numTerms is the number of terms for this operator (must
          be 1, 2, or 3)
       - rightLeftAssoc is the indicator whether the operator is
          right or left associative, using the pyparsing-defined
          constants C{opAssoc.RIGHT} and C{opAssoc.LEFT}.
       - parseAction is the parse action to be associated with
          expressions matching this operator expression (the
          parse action tuple member may be omitted)
     - lpar - expression for matching left-parentheses (default=C{Suppress('(')})
     - rpar - expression for matching right-parentheses (default=C{Suppress(')')})

    Example::
        # simple example of four-function arithmetic with ints and variable names
        integer = pyparsing_common.signed_integer
        varname = pyparsing_common.identifier 
        
        arith_expr = infixNotation(integer | varname,
            [
            ('-', 1, opAssoc.RIGHT),
            (oneOf('* /'), 2, opAssoc.LEFT),
            (oneOf('+ -'), 2, opAssoc.LEFT),
            ])
        
        arith_expr.runTests('''
            5+3*6
            (5+3)*6
            -2--11
            ''', fullDump=False)
    prints::
        5+3*6

    Helper method for defining nested lists enclosed in opening and closing
    delimiters ("(" and ")" are the default).

    Parameters:
     - opener - opening character for a nested list (default=C{"("}); can also be a pyparsing expression
     - closer - closing character for a nested list (default=C{")"}); can also be a pyparsing expression
     - content - expression for items within the nested lists (default=C{None})
     - ignoreExpr - expression for ignoring opening and closing delimiters (default=C{quotedString})

    If an expression is not provided for the content argument, the nested
    expression will capture all whitespace-delimited content between delimiters
    as a list of separate values.

    Use the C{ignoreExpr} argument to define expressions that may contain
    opening or closing characters that should not be treated as opening
    or closing characters for nesting, such as quotedString or a comment
    expression.  Specify multiple expressions using an C{L{Or}} or C{L{MatchFirst}}.
    The default is L{quotedString}, but if no expressions are to be ignored,
    then pass C{None} for this argument.

    Example::
        data_type = oneOf("void int short long char float double")
        decl_data_type = Combine(data_type + Optional(Word('*')))
        ident = Word(alphas+'_', alphanums+'_')
        number = pyparsing_common.number
        arg = Group(decl_data_type + ident)

                      + code_body("body"))

    Helper method for defining space-delimited indentation blocks, such as
    those used to define block statements in Python source code.

    Parameters:
     - blockStatementExpr - expression defining syntax of statement that
            is repeated within the indented block
     - indentStack - list created by caller to manage indentation stack
            (multiple statementWithIndentedBlock expressions within a single grammar
            should share a common indentStack)
     - indent - boolean indicating whether block must be indented beyond the
            the current level; set to False for block of left-most statements
            (default=C{True})

    A valid block must contain at least one C{blockStatement}.

pyparsing module - Classes and methods to define and execute parsing grammars

The pyparsing module is an alternative approach to creating and executing simple grammars,
vs. the traditional lex/yacc approach, or the use of regular expressions.  With pyparsing, you
don't need to learn a new syntax for defining grammars or matching expressions - the parsing module
provides a library of classes that you use to construct the grammar directly in Python.

Here is a program to parse "Hello, World!" (or any greeting of the form 
C{", !"}), built up using L{Word}, L{Literal}, and L{And} elements 
(L{'+'} operator gives L{And} expressions, strings are auto-converted to
L{Literal} expressions)::

    from pyparsing import Word, alphas

    # define grammar of a greeting
    greet = Word(alphas) + "," + Word(alphas) + "!"

    hello = "Hello, World!"
    print (hello, "->", greet.parseString(hello))

The program outputs the following::

    Hello, World! -> ['Hello', ',', 'World', '!']

The Python representation of the grammar is quite readable, owing to the self-explanatory
class names, and the use of '+', '|' and '^' operators.

The L{ParseResults} object returned from L{ParserElement.parseString} can be accessed as a nested list, a dictionary, or an
object with named attributes.

The pyparsing module handles some of the problems that are typically vexing when writing text parsers:
 - extra or missing whitespace (the above program will also handle "Hello,World!", "Hello  ,  World  !", etc.)
 - quoted strings
 - embedded comments

        Removes and returns item at specified index (default=C{last}).
        Supports both C{list} and C{dict} semantics for C{pop()}. If passed no
        argument or an integer argument, it will use C{list} semantics
        and pop tokens from the list of parsed tokens. If passed a 
        non-integer argument (most likely a string), it will use C{dict}
        semantics and pop the corresponding value from any defined 
        results names. A second default return value argument is 
        supported, just as in C{dict.pop()}.

        this is so that the client can define a basic element, such as an
        integer, and reference it in multiple places with different names.

        Define action to perform when successfully matching parse element definition.
        Parse action fn is a callable method with 0-3 arguments, called as C{fn(s,loc,toks)},
        C{fn(loc,toks)}, C{fn(toks)}, or just C{fn()}, where:
         - s   = the original string being parsed (see note below)
         - loc = the location of the matching substring
         - toks = a list of the matched tokens, packaged as a C{L{ParseResults}} object
        If the functions in fns modify the tokens, they can return them as the return
        value from fn, and the modified list of tokens will replace the original.
        Otherwise, fn does not need to return any value.

        Optional keyword arguments:
         - callDuringTry = (default=C{False}) indicate if parse action should be run during lookaheads and alternate testing

        Note: the default parsing behavior is to expand tabs in the input string
        before starting the parsing process.  See L{I{parseString}} for more information
        on parsing strings containing C{}s, and suggested methods to maintain a
        consistent view of the parsed string, the parse location, and line and column
        positions within the parsed string.
        
        Example::
            integer = Word(nums)
            date_str = integer + '/' + integer + '/' + integer

            date_str.parseString("1999/12/31")  # -> ['1999', '/', '12', '/', '31']

            # use parse action to convert to ints at parse time
            integer = Word(nums).setParseAction(lambda toks: int(toks[0]))
            date_str = integer + '/' + integer + '/' + integer

            # note that integer fields are now ints, not strings
            date_str.parseString("1999/12/31")  # -> [1999, '/', 12, '/', 31]

        Extension to C{L{scanString}}, to modify matching text with modified tokens that may
        be returned from a parse action.  To use C{transformString}, define a grammar and
        attach a parse action to it that modifies the returned token list.
        Invoking C{transformString()} on a target string will then scan for matches,
        and replace the matched text patterns according to the logic in the parse
        action.  C{transformString()} returns the resulting transformed string.
        
        Example::
            wd = Word(alphas)
            wd.setParseAction(lambda toks: toks[0].title())

         - C{expr*(None,None)} is equivalent to C{L{ZeroOrMore}(expr)}
         - C{expr*(1,None)} is equivalent to C{L{OneOrMore}(expr)}

        matching; may be called repeatedly, to define multiple comment or other
        ignorable patterns.
        
        Example::
            patt = OneOrMore(Word(alphas))
            patt.parseString('ablaj /* comment */ lskjd') # -> ['ablaj']

        The output shown is that produced by the default debug actions - custom debug actions can be
        specified using L{setDebugActions}. Prior to attempting
        to match the C{wd} expression, the debugging message C{"Match  at loc (,)"}
        is shown. Then if the parse succeeds, a C{"Matched"} message is shown, or an C{"Exception raised"}
        message is shown. Also note the use of L{setName} to assign a human-readable name to the expression,
        which makes debugging and exception messages easier to understand - for instance, the default
        name created for the C{Word} expression without calling C{setName} is C{"W:(ABCD...)"}.

        Execute the parse expression on a series of test strings, showing each
        test, the parsed results or where the parse failed. Quick and easy way to
        run a parse expression against a list of sample strings.
           
        Parameters:
         - tests - a list of separate test strings, or a multiline string of test strings
         - parseAll - (default=C{True}) - flag to pass to C{L{parseString}} when running tests           
         - comment - (default=C{'#'}) - expression for indicating embedded comments in the test 
              string; pass None to disable comment filtering
         - fullDump - (default=C{True}) - dump results as list followed by results names in nested outline;
              if False, only dump nested list
         - printResults - (default=C{True}) prints test output to stdout
         - failureTests - (default=C{False}) indicates if these tests are expected to fail parsing

        Returns: a (success, results) tuple, where success indicates that all tests succeeded
        (or failed if C{failureTests} is True), and the results contain a list of lines of each 
        test's output
        
        Example::
            number_expr = pyparsing_common.number.copy()

            result = number_expr.runTests('''
                # unsigned integer
                100
                # negative integer

                ''')
            print("Success" if result[0] else "Failed!")

            result = number_expr.runTests('''

            print("Success" if result[0] else "Failed!")
        prints::

            Success

        Each test string must be on a single line. If you want to test a string that spans multiple
        lines, create a test like this::

            expr.runTest(r"this is a test\n of strings that spans \n 3 lines")
        
        (Note that this is a raw string literal, you must include the leading 'r'.)

    Token to exactly match a specified string as a keyword, that is, it must be
    immediately followed by a non-keyword character.  Compare with C{L{Literal}}:
     - C{Literal("if")} will match the leading C{'if'} in C{'ifAndOnlyIf'}.
     - C{Keyword("if")} will not; it will only match the leading C{'if'} in C{'if x=1'}, or C{'if(y==2)'}
    Accepts two optional constructor arguments in addition to the keyword string:
     - C{identChars} is a string of characters that would be valid identifier characters,
          defaulting to all alphanumerics + "_" and "$"
     - C{caseless} allows case-insensitive matching, default is C{False}.

    A variation on L{Literal} which matches "close" matches, that is, 
    strings with at most 'n' mismatching characters. C{CloseMatch} takes parameters:
     - C{match_string} - string to be matched
     - C{maxMismatches} - (C{default=1}) maximum number of mismatches allowed to count as a match
    
    The results from a successful parse will contain the matched text from the input string and the following named results:
     - C{mismatches} - a list of the positions within the match_string where mismatches were found
     - C{original} - the original match_string used to compare against the input string
    
    If C{mismatches} is an empty list, then the match was an exact match.

    Token for matching words composed of allowed character sets.
    Defined with string containing all allowed initial characters,
    an optional string containing allowed body characters (if omitted,
    defaults to the initial character set), and an optional minimum,
    maximum, and/or exact length.  The default value for C{min} is 1 (a
    minimum value < 1 is not valid); the default values for C{max} and C{exact}
    are 0, meaning no maximum or exact length restriction. An optional
    C{excludeChars} parameter can list characters that might be found in 
    the input C{bodyChars} string; useful to define a word of all printables
    except for one or two characters, for instance.
    
    L{srange} is useful for defining custom character set strings for defining 
    C{Word} expressions, using range notation from regular expression character sets.
    
    A common mistake is to use C{Word} to match a specific literal string, as in 
    C{Word("Address")}. Remember that C{Word} uses the string argument to define
    I{sets} of matchable characters. This expression would match "Add", "AAA",
    "dAred", or any other word made up of the characters 'A', 'd', 'r', 'e', and 's'.
    To match an exact literal string, use L{Literal} or L{Keyword}.

    pyparsing includes helper strings for building Words:
     - L{alphas}
     - L{nums}
     - L{alphanums}
     - L{hexnums}
     - L{alphas8bit} (alphabetic characters in ASCII range 128-255 - accented, tilded, umlauted, etc.)
     - L{punc8bit} (non-alphabetic characters in ASCII range 128-255 - currency, symbols, superscripts, diacriticals, etc.)
     - L{printables} (any non-whitespace character)

    Example::
        # a word composed of digits
        integer = Word(nums) # equivalent to Word("0123456789") or Word(srange("0-9"))
        
        # a word with a leading capital, and zero or more lowercase
        capital_word = Word(alphas.upper(), alphas.lower())

        # hostnames are alphanumeric, with leading alpha, and '-'
        hostname = Word(alphas, alphanums+'-')
        
        # roman numeral (not a strict parser, accepts invalid mix of characters)
        roman = Word("IVXLCDM")
        
        # any string of non-whitespace characters, except for ','
        csv_value = Word(printables, excludeChars=",")

    Token for matching strings that match a given regular expression.
    Defined with string specifying the regular expression in a form recognized by the inbuilt Python re module.
    If the given regex contains named groups (defined using C{(?P...)}), these will be preserved as 
    named parse results.

    Example::
        realnum = Regex(r"[+-]?\d+\.\d*")
        date = Regex(r'(?P\d{4})-(?P\d\d?)-(?P\d\d?)')

    Token for matching strings that are delimited by quoting characters.
    
    Defined with the following parameters:
        - quoteChar - string of one or more characters defining the quote delimiting string
        - escChar - character to escape quotes, typically backslash (default=C{None})
        - escQuote - special quote sequence to escape an embedded quote string (such as SQL's "" to escape an embedded ") (default=C{None})
        - multiline - boolean indicating whether quotes can span multiple lines (default=C{False})
        - unquoteResults - boolean indicating whether the matched text should be unquoted (default=C{True})
        - endQuoteChar - string of one or more characters defining the end of the quote delimited string (default=C{None} => same as quoteChar)
        - convertWhitespaceEscapes - convert escaped whitespace (C{'\t'}, C{'\n'}, etc.) to actual whitespace (default=C{True})

    Example::
        qs = QuotedString('"')
        print(qs.searchString('lsjdf "This is the quote" sldjf'))
        complex_qs = QuotedString('{{', endQuoteChar='}}')
        print(complex_qs.searchString('lsjdf {{This is the "quote"}} sldjf'))
        sql_qs = QuotedString('"', escQuote='""')
        print(sql_qs.searchString('lsjdf "This is the quote with ""embedded"" quotes" sldjf'))
    prints::

    Token for matching words composed of characters I{not} in a given set (will
    include whitespace in matched characters if not listed in the provided exclusion set - see example).
    Defined with string containing all disallowed characters, and an optional
    minimum, maximum, and/or exact length.  The default value for C{min} is 1 (a
    minimum value < 1 is not valid); the default values for C{max} and C{exact}
    are 0, meaning no maximum or exact length restriction.

    Example::
        # define a comma-separated-value as anything that is not a ','
        csv_value = CharsNotIn(',')
        print(delimitedList(csv_value).parseString("dkls,lsdkjf,s12 34,@!#,213"))

    where the leading integer tells how many expr expressions follow.
    The matched tokens returns the array of expr tokens as a list - the leading count token is suppressed.
    
    If C{intExpr} is specified, it should be a pyparsing expression that produces an integer value.

    Example::
        countedArray(Word(alphas)).parseString('2 ab cd ef')  # -> ['ab', 'cd']

        # in this parser, the leading integer value is given in binary,
        # '10' indicating that 2 values are in the array
        binaryConstant = Word('01').setParseAction(lambda t: int(t[0], 2))
        countedArray(Word(alphas), intExpr=binaryConstant).parseString('10 ab cd ef')  # -> ['ab', 'cd']

    Helper to quickly define a set of alternative Literals, and makes sure to do
    longest-first testing when there is a conflict, regardless of the input order,
    but returns a C{L{MatchFirst}} for best performance.

    Parameters:
     - strs - a string of space-delimited literals, or a collection of string literals
     - caseless - (default=C{False}) - treat all literals as caseless
     - useRegex - (default=C{True}) - as an optimization, will generate a Regex
          object; otherwise, will generate a C{MatchFirst} object (if C{caseless=True}, or
          if creating a C{Regex} raises an exception)

    Example::

    Helper to easily and clearly define a dictionary by specifying the respective patterns
    for the key and value.  Takes care of defining the C{L{Dict}}, C{L{ZeroOrMore}}, and C{L{Group}} tokens
    in the proper order.  The key pattern can include delimiting markers or punctuation,
    as long as they are suppressed, thereby leaving the significant key text.  The value
    pattern can include named results, so that the C{Dict} results can include named token
    fields.

    Example::
        text = "shape: SQUARE posn: upper left color: light blue texture: burlap"
        attr_expr = (label + Suppress(':') + OneOrMore(data_word, stopOn=label).setParseAction(' '.join))

        attr_value = Suppress(':') + OneOrMore(data_word, stopOn=label).setParseAction(' '.join)

        # similar to Dict, but simpler call format

    Helper to return the original, untokenized text for a given expression.  Useful to
    restore the parsed fields of an HTML start tag into the raw tag text itself, or to
    revert separate tokens with intervening whitespace back to the original matching
    input text. By default, returns astring containing the original parsed text.  
       
    If the optional C{asString} argument is passed as C{False}, then the return value is a 
    C{L{ParseResults}} containing any results names that were originally matched, and a 
    single token containing the original matched text from the input string.  So if 
    the expression passed to C{L{originalTextFor}} contains expressions with defined
    results names, you must set C{asString} to C{False} if you want to preserve those
    results name values.

    Example::
        src = "this is test  bold text  normal text "
        for tag in ("b","i"):
            opener,closer = makeHTMLTags(tag)

    Helper to create a validating parse action to be used with start tags created

    with a required attribute value, to avoid false matches on common tags such as
    C{} or C{

    Call C{withAttribute} with a series of attribute names and values. Specify the list
    of filter attributes names and values as:
     - keyword arguments, as in C{(align="right")}, or
     - as an explicit dict with C{**} operator, when an attribute name is also a Python
          reserved word, as in C{**{"class":"Customer", "align":"right"}}
     - a list of name-value tuples, as in ( ("ns1:class", "Customer"), ("ns2:align","right") )
    For attribute names with a namespace prefix, you must use the second form.  Attribute
    names are matched insensitive to upper/lower case.
       
    If just testing for C{class} (with or without a namespace), use C{L{withClass}}.

    To verify that the attribute exists, but without specifying a value, pass
    C{withAttribute.ANY_VALUE} as the value.

    Helper method for constructing grammars of expressions made up of
    operators working in a precedence hierarchy.  Operators may be unary or
    binary, left- or right-associative.  Parse actions can also be attached
    to operator expressions. The generated parser will also recognize the use 
    of parentheses to override operator precedences (see example below).
    
    Note: if you define a deep operator list, you may see performance issues
    when using infixNotation. See L{ParserElement.enablePackrat} for a
    mechanism to potentially improve your parser performance.

    Parameters:
     - baseExpr - expression representing the most basic element for the nested
     - opList - list of tuples, one for each operator precedence level in the
      expression grammar; each tuple is of the form
      (opExpr, numTerms, rightLeftAssoc, parseAction), where:
       - opExpr is the pyparsing expression for the operator;
          may also be a string, which will be converted to a Literal;
          if numTerms is 3, opExpr is a tuple of two expressions, for the
          two operators separating the 3 terms
       - numTerms is the number of terms for this operator (must
          be 1, 2, or 3)
       - rightLeftAssoc is the indicator whether the operator is
          right or left associative, using the pyparsing-defined
          constants C{opAssoc.RIGHT} and C{opAssoc.LEFT}.
       - parseAction is the parse action to be associated with
          expressions matching this operator expression (the
          parse action tuple member may be omitted)
     - lpar - expression for matching left-parentheses (default=C{Suppress('(')})
     - rpar - expression for matching right-parentheses (default=C{Suppress(')')})

    Example::
        # simple example of four-function arithmetic with ints and variable names
        integer = pyparsing_common.signed_integer
        varname = pyparsing_common.identifier 
        
        arith_expr = infixNotation(integer | varname,
            [
            ('-', 1, opAssoc.RIGHT),
            (oneOf('* /'), 2, opAssoc.LEFT),
            (oneOf('+ -'), 2, opAssoc.LEFT),
            ])
        
        arith_expr.runTests('''

            (5+3)*6

    Helper method for defining nested lists enclosed in opening and closing
    delimiters ("(" and ")" are the default).

    Parameters:
     - opener - opening character for a nested list (default=C{"("}); can also be a pyparsing expression
     - closer - closing character for a nested list (default=C{")"}); can also be a pyparsing expression
     - content - expression for items within the nested lists (default=C{None})
     - ignoreExpr - expression for ignoring opening and closing delimiters (default=C{quotedString})

    If an expression is not provided for the content argument, the nested
    expression will capture all whitespace-delimited content between delimiters
    as a list of separate values.

    Use the C{ignoreExpr} argument to define expressions that may contain
    opening or closing characters that should not be treated as opening
    or closing characters for nesting, such as quotedString or a comment
    expression.  Specify multiple expressions using an C{L{Or}} or C{L{MatchFirst}}.
    The default is L{quotedString}, but if no expressions are to be ignored,
    then pass C{None} for this argument.

    Example::
        data_type = oneOf("void int short long char float double")
        decl_data_type = Combine(data_type + Optional(Word('*')))
        ident = Word(alphas+'_', alphanums+'_')
        number = pyparsing_common.number
        arg = Group(decl_data_type + ident)
        LPAR,RPAR = map(Suppress, "()")

        code_body = nestedExpr('{', '}', ignoreExpr=(quotedString | cStyleComment))

        c_function = (decl_data_type("type") 
                      + ident("name")
                      + LPAR + Optional(delimitedList(arg), [])("args") + RPAR 
                      + code_body("body"))
        c_function.ignore(cStyleComment)

    Helper method for defining space-delimited indentation blocks, such as
    those used to define block statements in Python source code.

    Parameters:
     - blockStatementExpr - expression defining syntax of statement that
            is repeated within the indented block
     - indentStack - list created by caller to manage indentation stack
            (multiple statementWithIndentedBlock expressions within a single grammar
            should share a common indentStack)
     - indent - boolean indicating whether block must be indented beyond the
            the current level; set to False for block of left-most statements
            (default=C{True})

    A valid block must contain at least one C{blockStatement}.

    Example::
        data = '''
        def A(z):
          A1
          B = 100

    Here are some common low-level expressions that may be useful in jump-starting parser development:
     - numeric forms (L{integers}, L{reals}, L{scientific notation})
     - common L{programming identifiers}
     - network addresses (L{MAC}, L{IPv4}, L{IPv6})
     - ISO8601 L{dates} and L{datetime}
     - L{UUID}
     - L{comma-separated list}

Wtd|dS(sUnpack `filename` to `extract_dir`, or raise ``UnrecognizedFormat``

    `progress_filter` is a function taking two arguments: a source path
    internal to the archive ('/'-separated), and a filesystem path where it
    will be extracted.  The callback must return the desired extract path
    (which may be the same as the one passed in), or else ``None`` to skip
    that file or directory.  The callback can thus be used to report on the
    progress of the extraction, as well as to filter the items extracted or
    alter their extraction paths.

    `drivers`, if supplied, must be a non-empty sequence of functions with the
    same signature as this function (minus the `drivers` argument), that raise
    ``UnrecognizedFormat`` if they do not support extracting the designated
    archive type.  The `drivers` are tried in sequence until one is found that
    does not raise an error, or until all are exhausted (in which case
    ``UnrecognizedFormat`` is raised).  If you do not supply a sequence of
    drivers, the module's ``extraction_drivers`` constant will be used, which
    means that ``unpack_zipfile`` and ``unpack_tarfile`` will be tried, in that
    order.

ZddZdddZddZdS(s-A PEP 517 interface to setuptools

Previously, when a user or a command line tool (let's call it a "frontend")
needed to make a request of setuptools to take a certain action, for
example, generating a list of installation requirements, the frontend would
would call "setup.py egg_info" or "setup.py bdist_wheel" on the command line.

PEP 517 defines a different method of interfacing with setuptools. Rather
than calling "setup.py" directly, the frontend should:

  1. Set the current directory to the directory with a setup.py file
  2. Import this module into a safe python interpreter (one in which
     setuptools can potentially set global variables or crash hard).
  3. Call one of the functions defined in PEP 517.

What each function does is defined in PEP 517. However, here is a "casual"
definition of the functions (this definition should not be relied on for
bug reports or API stability):

  - `build_wheel`: build a wheel in the folder and return the basename
  - `get_requires_for_build_wheel`: get the `setup_requires` to build
  - `prepare_metadata_for_build_wheel`: get the `install_requires`
  - `build_sdist`: build an sdist in the folder and return the basename
  - `get_requires_for_build_sdist`: get the `setup_requires` to build

Again, this is not a formal definition! Just a "taste" of the module.

    The data files are specified via a 'package_data' argument to 'setup()'.
    See 'setuptools.dist.Distribution' for more details.

    Also, this version of the 'build_py' command allows you to specify both
    'py_modules' and 'packages' in the same setup operation.

    1. Run egg_info to ensure the name and version are properly calculated.
    2. Always run 'install' using --single-version-externally-managed to
       disable eggs in RPM distributions.
    3. Replace dash with underscore in the version numbers for better RPM

    This is an enhanced version of 'distutils.dist.Distribution' that
    effectively adds the following new optional keyword arguments to 'setup()':

     'install_requires' -- a string or sequence of strings specifying project
        versions that the distribution requires when installed, in the format
        used by 'pkg_resources.require()'.  They will be installed
        automatically when the package is installed.  If you wish to use
        packages that are not available in PyPI, or want to give your users an
        alternate download location, you can add a 'find_links' option to the
        '[easy_install]' section of your project's 'setup.cfg' file, and then
        setuptools will scan the listed web pages for links that satisfy the
        requirements.

     'extras_require' -- a dictionary mapping names of optional "extras" to the
        additional requirement(s) that using those extras incurs. For example,
        this::

            extras_require = dict(reST = ["docutils>=0.3", "reSTedit"])

        indicates that the distribution can optionally provide an extra
        capability called "reST", but it can only be used if docutils and
        reSTedit are installed.  If the user installs your package using
        EasyInstall and requests one of your extras, the corresponding
        additional requirements will be installed if needed.

     'features' **deprecated** -- a dictionary mapping option names to
        'setuptools.Feature'
        objects.  Features are a portion of the distribution that can be
        included or excluded based on user options, inter-feature dependencies,
        and availability on the current system.  Excluded features are omitted
        from all setup commands, including source and binary distributions, so
        you can create multiple distributions from the same source tree.
        Feature names should be valid Python identifiers, except that they may
        contain the '-' (minus) sign.  Features can be included or excluded
        via the command line options '--with-X' and '--without-X', where 'X' is
        the name of the feature.  Whether a feature is included by default, and
        whether you are allowed to control this from the command line, is
        determined by the Feature object.  See the 'Feature' class for more
        information.

     'test_suite' -- the name of a test suite to run for the 'test' command.
        If the user runs 'python setup.py test', the package will be installed,
        and the named test suite will be run.  The format is the same as
        would be used on a 'unittest.py' command line.  That is, it is the
        dotted name of an object to import and call to generate a test suite.

     'package_data' -- a dictionary mapping package names to lists of filenames
        or globs to use to find data files contained in the named packages.
        If the dictionary has filenames or globs listed under '""' (the empty
        string), those names will be searched for in every package, in addition
        to any names for the specific package.  Data files found using these
        names/globs will be installed along with the package, in the same
        location as the package.  Note that globs are allowed to reference
        the contents of non-package subdirectories, as long as you use '/' as
        a path separator.  (Globs are automatically converted to
        platform-specific paths at runtime.)

    In addition to these new keywords, this class also has several new methods
    for manipulating the distribution's contents.  For example, the 'include()'
    and 'exclude()' methods can be thought of as in-place add and subtract
    commands that add or remove packages, modules, extensions, and so on from
    the distribution.  They are used by the feature subsystem to configure the
    distribution for the included and excluded features.

    **deprecated** -- The `Feature` facility was never completely implemented
    or supported, `has reported issues
    `_ and will be removed in
    a future version.

    A subset of the distribution that can be excluded if unneeded/wanted

    Features are created using these keyword arguments:

      'description' -- a short, human readable description of the feature, to
         be used in error messages, and option help messages.

      'standard' -- if true, the feature is included by default if it is
         available on the current system.  Otherwise, the feature is only
         included if requested via a command line '--with-X' option, or if
         another included feature requires it.  The default setting is 'False'.

      'available' -- if true, the feature is available for installation on the
         current system.  The default setting is 'True'.

      'optional' -- if true, the feature's inclusion can be controlled from the
         command line, using the '--with-X' or '--without-X' options.  If
         false, the feature's inclusion status is determined automatically,
         based on 'availabile', 'standard', and whether any other feature
         requires it.  The default setting is 'True'.

      'require_features' -- a string or sequence of strings naming features
         that should also be included if this feature is included.  Defaults to
         empty list.  May also contain 'Require' objects that should be
         added/removed from the distribution.

      'remove' -- a string or list of strings naming packages to be removed
         from the distribution if this feature is *not* included.  If the
         feature *is* included, this argument is ignored.  This argument exists
         to support removing features that "crosscut" a distribution, such as
         defining a 'tests' feature that removes all the 'tests' subpackages
         provided by other features.  The default for this argument is an empty
         list.  (Note: the named package(s) or modules must exist in the base
         distribution when the 'setup()' function is initially called.)

      other keywords -- any other keyword arguments are saved, and passed to
         the distribution's 'include()' and 'exclude()' methods when the
         feature is included or excluded, respectively.  So, for example, you
         could pass 'packages=["a","b"]' to cause packages 'a' and 'b' to be
         added or removed from the distribution as appropriate.

    A feature must include at least one 'requires', 'remove', or other
    keyword argument.  Otherwise, it can't affect the distribution in any way.
    Note also that you can subclass 'Feature' to create your own specialized
    feature types that modify the distribution in other ways when included or
    excluded.  See the docstrings for the various methods here for more detail.
    Aside from the methods, the only feature attributes that distributions look
    at are 'description' and 'optional'.

||ddS(sLocate and/or download `spec` to `tmpdir`, returning a local path

        `spec` may be a ``Requirement`` object, or a string containing a URL,
        an existing local filename, or a project/version requirement spec
        (i.e. the string form of a ``Requirement`` object).  If it is the URL
        of a .py file with an unambiguous ``#egg=name-version`` tag (i.e., one
        that escapes ``-`` as ``_`` throughout), a trivial ``setup.py`` is
        automatically created alongside the downloaded file.

        If `spec` is a ``Requirement`` object or a string containing a
        project/version requirement spec, this method returns the location of
        a matching distribution (possibly after downloading it to `tmpdir`).
        If `spec` is a locally existing file or directory name, it is simply
        returned unchanged.  If `spec` is a URL, it is downloaded to a subpath
        of `tmpdir`, and the local filename is returned.  Various errors may be
        raised if a problem occurs during downloading.

        `requirement` must be a ``pkg_resources.Requirement`` instance.
        If necessary, or if the `force_scan` flag is set, the requirement is
        searched for in the (online) package index as well as the locally
        installed packages.  If a distribution matching `requirement` is found,
        the returned distribution's ``location`` is the value you would have
        gotten from calling the ``download()`` method with the matching
        distribution's URL or filename.  If no matching distribution is found,
        ``None`` is returned.

        If the `source` flag is set, only source distributions and source
        checkout links will be considered.  Unless the `develop_ok` flag is
        set, development and system eggs (i.e., those using the ``.egg-info``

    `progress_filter` is a function taking two arguments: a source path
    internal to the archive ('/'-separated), and a filesystem path where it
    will be extracted.  The callback must return the desired extract path
    (which may be the same as the one passed in), or else ``None`` to skip
    that file or directory.  The callback can thus be used to report on the
    progress of the extraction, as well as to filter the items extracted or
    alter their extraction paths.

    `drivers`, if supplied, must be a non-empty sequence of functions with the
    same signature as this function (minus the `drivers` argument), that raise
    ``UnrecognizedFormat`` if they do not support extracting the designated
    archive type.  The `drivers` are tried in sequence until one is found that
    does not raise an error, or until all are exhausted (in which case
    ``UnrecognizedFormat`` is raised).  If you do not supply a sequence of
    drivers, the module's ``extraction_drivers`` constant will be used, which
    means that ``unpack_zipfile`` and ``unpack_tarfile`` will be tried, in that
    order.

    This is an enhanced version of 'distutils.dist.Distribution' that
    effectively adds the following new optional keyword arguments to 'setup()':

     'install_requires' -- a string or sequence of strings specifying project
        versions that the distribution requires when installed, in the format
        used by 'pkg_resources.require()'.  They will be installed
        automatically when the package is installed.  If you wish to use
        packages that are not available in PyPI, or want to give your users an
        alternate download location, you can add a 'find_links' option to the
        '[easy_install]' section of your project's 'setup.cfg' file, and then
        setuptools will scan the listed web pages for links that satisfy the
        requirements.

     'extras_require' -- a dictionary mapping names of optional "extras" to the
        additional requirement(s) that using those extras incurs. For example,
        this::

            extras_require = dict(reST = ["docutils>=0.3", "reSTedit"])

        indicates that the distribution can optionally provide an extra
        capability called "reST", but it can only be used if docutils and
        reSTedit are installed.  If the user installs your package using
        EasyInstall and requests one of your extras, the corresponding
        additional requirements will be installed if needed.

     'features' **deprecated** -- a dictionary mapping option names to
        'setuptools.Feature'
        objects.  Features are a portion of the distribution that can be
        included or excluded based on user options, inter-feature dependencies,
        and availability on the current system.  Excluded features are omitted
        from all setup commands, including source and binary distributions, so
        you can create multiple distributions from the same source tree.
        Feature names should be valid Python identifiers, except that they may
        contain the '-' (minus) sign.  Features can be included or excluded
        via the command line options '--with-X' and '--without-X', where 'X' is
        the name of the feature.  Whether a feature is included by default, and
        whether you are allowed to control this from the command line, is
        determined by the Feature object.  See the 'Feature' class for more
        information.

     'test_suite' -- the name of a test suite to run for the 'test' command.
        If the user runs 'python setup.py test', the package will be installed,
        and the named test suite will be run.  The format is the same as
        would be used on a 'unittest.py' command line.  That is, it is the
        dotted name of an object to import and call to generate a test suite.

     'package_data' -- a dictionary mapping package names to lists of filenames
        or globs to use to find data files contained in the named packages.
        If the dictionary has filenames or globs listed under '""' (the empty
        string), those names will be searched for in every package, in addition
        to any names for the specific package.  Data files found using these
        names/globs will be installed along with the package, in the same
        location as the package.  Note that globs are allowed to reference
        the contents of non-package subdirectories, as long as you use '/' as
        a path separator.  (Globs are automatically converted to
        platform-specific paths at runtime.)

    In addition to these new keywords, this class also has several new methods
    for manipulating the distribution's contents.  For example, the 'include()'
    and 'exclude()' methods can be thought of as in-place add and subtract
    commands that add or remove packages, modules, extensions, and so on from
    the distribution.  They are used by the feature subsystem to configure the
    distribution for the included and excluded features.

WdS(sRemove items from distribution that are named in keyword arguments

        For example, 'dist.exclude(py_modules=["x"])' would remove 'x' from
        the distribution's 'py_modules' attribute.  Excluding packages uses
        the 'exclude_package()' method, so all of the package's contained
        packages, modules, and extensions are also excluded.

        Currently, this method only supports exclusion from attributes that are
        lists or tuples.  If you need to add support for excluding from other
        attributes in this or a subclass, you can add an '_exclude_X' method,
        where 'X' is the name of the attribute.  The method will be called with
        the value passed to 'exclude()'.  So, 'dist.exclude(foo={"bar":"baz"})'
        will try to call 'dist._exclude_foo({"bar":"baz"})', which can then
        handle whatever special exclusion logic is needed.

    a future version.

    A subset of the distribution that can be excluded if unneeded/wanted

    Features are created using these keyword arguments:

      'description' -- a short, human readable description of the feature, to
         be used in error messages, and option help messages.

      'standard' -- if true, the feature is included by default if it is
         available on the current system.  Otherwise, the feature is only
         included if requested via a command line '--with-X' option, or if
         another included feature requires it.  The default setting is 'False'.

      'available' -- if true, the feature is available for installation on the
         current system.  The default setting is 'True'.

      'optional' -- if true, the feature's inclusion can be controlled from the
         command line, using the '--with-X' or '--without-X' options.  If
         false, the feature's inclusion status is determined automatically,
         based on 'availabile', 'standard', and whether any other feature
         requires it.  The default setting is 'True'.

      'require_features' -- a string or sequence of strings naming features
         that should also be included if this feature is included.  Defaults to
         empty list.  May also contain 'Require' objects that should be
         added/removed from the distribution.

      'remove' -- a string or list of strings naming packages to be removed
         from the distribution if this feature is *not* included.  If the
         feature *is* included, this argument is ignored.  This argument exists
         to support removing features that "crosscut" a distribution, such as
         defining a 'tests' feature that removes all the 'tests' subpackages
         provided by other features.  The default for this argument is an empty
         list.  (Note: the named package(s) or modules must exist in the base
         distribution when the 'setup()' function is initially called.)

      other keywords -- any other keyword arguments are saved, and passed to
         the distribution's 'include()' and 'exclude()' methods when the
         feature is included or excluded, respectively.  So, for example, you
         could pass 'packages=["a","b"]' to cause packages 'a' and 'b' to be
         added or removed from the distribution as appropriate.

    A feature must include at least one 'requires', 'remove', or other
    keyword argument.  Otherwise, it can't affect the distribution in any way.
    Note also that you can subclass 'Feature' to create your own specialized
    feature types that modify the distribution in other ways when included or
    excluded.  See the docstrings for the various methods here for more detail.
    Aside from the methods, the only feature attributes that distributions look
    at are 'description' and 'optional'.

WdS(sVerify that feature makes sense in context of distribution

        This method is called by the distribution just before it parses its
        command line.  It checks to ensure that the 'remove' attribute, if any,
        contains only valid package/module names that are present in the base
        distribution when 'setup()' is called.  You may override it in a
        subclass to perform any other required validation of the feature

||ddS(sLocate and/or download `spec` to `tmpdir`, returning a local path

        `spec` may be a ``Requirement`` object, or a string containing a URL,
        an existing local filename, or a project/version requirement spec
        (i.e. the string form of a ``Requirement`` object).  If it is the URL
        of a .py file with an unambiguous ``#egg=name-version`` tag (i.e., one
        that escapes ``-`` as ``_`` throughout), a trivial ``setup.py`` is
        automatically created alongside the downloaded file.

        If `spec` is a ``Requirement`` object or a string containing a
        project/version requirement spec, this method returns the location of
        a matching distribution (possibly after downloading it to `tmpdir`).
        If `spec` is a locally existing file or directory name, it is simply
        returned unchanged.  If `spec` is a URL, it is downloaded to a subpath
        of `tmpdir`, and the local filename is returned.  Various errors may be
        raised if a problem occurs during downloading.

        `requirement` must be a ``pkg_resources.Requirement`` instance.
        If necessary, or if the `force_scan` flag is set, the requirement is
        searched for in the (online) package index as well as the locally
        installed packages.  If a distribution matching `requirement` is found,
        the returned distribution's ``location`` is the value you would have
        gotten from calling the ``download()`` method with the matching
        distribution's URL or filename.  If no matching distribution is found,
        ``None`` is returned.

        If the `source` flag is set, only source distributions and source
        checkout links will be considered.  Unless the `develop_ok` flag is
        set, development and system eggs (i.e., those using the ``.egg-info``
        format) will be ignored.
