-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{"<salutation>, <addressee>!"}), built up using L{Word}, L{Literal}, and L{And} elements
-(L{'+'<ParserElement.__add__>} 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<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
-
-
-Getting Started -
------------------
-Visit the classes L{ParserElement} and L{ParseResults} to see the base classes that most other pyparsing
-classes inherit from. Use the docstrings for examples of how to:
- - construct literal match expressions from L{Literal} and L{CaselessLiteral} classes
- - construct character word-group expressions using the L{Word} class
- - see how to create repetitive expressions using L{ZeroOrMore} and L{OneOrMore} classes
- - use L{'+'<And>}, L{'|'<MatchFirst>}, L{'^'<Or>}, and L{'&'<Each>} operators to combine simple expressions into more complex ones
- - associate names with your parsed results using L{ParserElement.setResultsName}
- - find some helpful expression short-cuts like L{delimitedList} and L{oneOf}
- - find more useful common expressions in the L{pyparsing_common} namespace class

- Repeated parse attempts at the same string location (which happens

- both valid results and parsing exceptions.

- 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

-
- 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,

- 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())

- """
- 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); if the parse action
- is passed a tuple or list of functions, this is equivalent to
- calling C{setParseAction(*fn)} (L{ParserElement.setParseAction})
- - lpar - expression for matching left-parentheses (default=C{Suppress('(')})
- - rpar - expression for matching right-parentheses (default=C{Suppress(')')})

-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{"<salutation>, <addressee>!"}), built up using L{Word}, L{Literal}, and L{And} elements
-(L{'+'<ParserElement.__add__>} 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<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
-
-
-Getting Started -
------------------
-Visit the classes L{ParserElement} and L{ParseResults} to see the base classes that most other pyparsing
-classes inherit from. Use the docstrings for examples of how to:
- - construct literal match expressions from L{Literal} and L{CaselessLiteral} classes
- - construct character word-group expressions using the L{Word} class
- - see how to create repetitive expressions using L{ZeroOrMore} and L{OneOrMore} classes
- - use L{'+'<And>}, L{'|'<MatchFirst>}, L{'^'<Or>}, and L{'&'<Each>} operators to combine simple expressions into more complex ones
- - associate names with your parsed results using L{ParserElement.setResultsName}
- - find some helpful expression short-cuts like L{delimitedList} and L{oneOf}
- - find more useful common expressions in the L{pyparsing_common} namespace class

- This speedup may break existing programs that use parse actions that

- 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

- 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:

- 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

- 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); if the parse action
- is passed a tuple or list of functions, this is equivalent to
- calling C{setParseAction(*fn)} (L{ParserElement.setParseAction})

"""Distribution with support for 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. - - '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. - """ - - _DISTUTILS_UNSUPPORTED_METADATA = { - 'long_description_content_type': lambda: None, - 'project_urls': dict, - 'provides_extras': ordered_set.OrderedSet, - 'license_file': lambda: None, - 'license_files': lambda: None, - } - - _patched_dist = None - - def patch_missing_pkg_info(self, attrs): - # Fake up a replacement for the data that would normally come from - # PKG-INFO, but which might not yet be built if this is a fresh - # checkout. - # - if not attrs or 'name' not in attrs or 'version' not in attrs: - return - key = pkg_resources.safe_name(str(attrs['name'])).lower() - dist = pkg_resources.working_set.by_key.get(key) - if dist is not None and not dist.has_metadata('PKG-INFO'): - dist._version = pkg_resources.safe_version(str(attrs['version'])) - self._patched_dist = dist - - def __init__(self, attrs=None): - have_package_data = hasattr(self, "package_data") - if not have_package_data: - self.package_data = {} - attrs = attrs or {} - self.dist_files = [] - # Filter-out setuptools' specific options. - self.src_root = attrs.pop("src_root", None) - self.patch_missing_pkg_info(attrs) - self.dependency_links = attrs.pop('dependency_links', []) - self.setup_requires = attrs.pop('setup_requires', []) - for ep in pkg_resources.iter_entry_points('distutils.setup_keywords'): - vars(self).setdefault(ep.name, None) - _Distribution.__init__( - self, - { - k: v - for k, v in attrs.items() - if k not in self._DISTUTILS_UNSUPPORTED_METADATA - }, - ) - - self._set_metadata_defaults(attrs) - - self.metadata.version = self._normalize_version( - self._validate_version(self.metadata.version) - ) - self._finalize_requires() - - def _set_metadata_defaults(self, attrs): - """ - Fill-in missing metadata fields not supported by distutils. - Some fields may have been set by other tools (e.g. pbr). - Those fields (vars(self.metadata)) take precedence to - supplied attrs. - """ - for option, default in self._DISTUTILS_UNSUPPORTED_METADATA.items(): - vars(self.metadata).setdefault(option, attrs.get(option, default())) - - @staticmethod - def _normalize_version(version): - if isinstance(version, setuptools.sic) or version is None: - return version - - normalized = str(packaging.version.Version(version)) - if version != normalized: - tmpl = "Normalizing '{version}' to '{normalized}'" - warnings.warn(tmpl.format(**locals())) - return normalized - return version - - @staticmethod - def _validate_version(version): - if isinstance(version, numbers.Number): - # Some people apparently take "version number" too literally :) - version = str(version) - - if version is not None: - try: - packaging.version.Version(version) - except (packaging.version.InvalidVersion, TypeError): - warnings.warn( - "The version specified (%r) is an invalid version, this " - "may not work as expected with newer versions of " - "setuptools, pip, and PyPI.
