* Sat Nov 16 2019 arunAATTgmx.de- update to version 2.4.5:
* Fixed encoding when setup.py reads README.rst to include the project long description when uploading to PyPI. A stray unicode space in README.rst prevented the source install on systems whose default encoding is not \'utf-8\'.- changes from version 2.4.4:
* Unresolved symbol reference in 2.4.3 release was masked by stdout buffering in unit tests, thanks for the prompt heads-up, Ned Batchelder!- changes from version 2.4.3:
* Fixed a bug in ParserElement.__eq__ that would for some parsers create a recursion error at parser definition time. Thanks to Michael Clerx for the assist. (Addresses issue #123)
* Fixed bug in indentedBlock where a block that ended at the end of the input string could cause pyaprsing to loop forever. Raised as part of discussion on StackOverflow with geckos.
* Backports from pyparsing 3.0.0: + __diag__.enable_all_warnings() + Fixed bug in PrecededBy which caused infinite recursion, issue [#127] + support for using regex-compiled RE to construct Regex expressions
* Wed Oct 16 2019 tchvatalAATTsuse.com- Do not pull in setuptools dependency at all to avoid cycles
* Tue Aug 06 2019 tbechtoldAATTsuse.com- update to 2.4.2: - Updated the shorthand notation that has been added for repetition expressions: expr[min, max], with \'...\' valid as a min or max value - The defaults on all the `__diag__` switches have been set to False, to avoid getting alarming warnings. To use these diagnostics, set them to True after importing pyparsing. - Fixed bug introduced by the use of __getitem__ for repetition, overlooking Python\'s legacy implementation of iteration by sequentially calling __getitem__ with increasing numbers until getting an IndexError. Found during investigation of problem reported by murlock, merci! - Changed [...] to emit ZeroOrMore instead of OneOrMore. - Removed code that treats ParserElements like iterables. - Change all __diag__ switches to False.- update to 2.4.1.1: - API change adding support for `expr[...]` - the original code in 2.4.1 incorrectly implemented this as OneOrMore. Code using this feature under this relase should explicitly use `expr[0, ...]` for ZeroOrMore and `expr[1, ...]` for OneOrMore. In 2.4.2 you will be able to write `expr[...]` equivalent to `ZeroOrMore(expr)`. - Bug if composing And, Or, MatchFirst, or Each expressions using an expression. This only affects code which uses explicit expression construction using the And, Or, etc. classes instead of using overloaded operators \'+\', \'^\', and so on. If constructing an And using a single expression, you may get an error that \"cannot multiply ParserElement by 0 or (0, 0)\" or a Python `IndexError`. - Some newly-added `__diag__` switches are enabled by default, which may give rise to noisy user warnings for existing parsers.- update to 2.4.1: - A new shorthand notation has been added for repetition expressions: expr[min, max], with \'...\' valid as a min - \'...\' can also be used as short hand for SkipTo when used in adding parse expressions to compose an And expression. - \'...\' can also be used as a \"skip forward in case of error\" expression - Improved exception messages to show what was actually found, not just what was expected. - Added diagnostic switches to help detect and warn about common parser construction mistakes, or enable additional parse debugging. Switches are attached to the pyparsing.__diag__ namespace object - Added ParseResults.from_dict classmethod, to simplify creation of a ParseResults with results names using a dict, which may be nested. This makes it easy to add a sub-level of named items to the parsed tokens in a parse action. - Added asKeyword argument (default=False) to oneOf, to force keyword-style matching on the generated expressions. - ParserElement.runTests now accepts an optional \'file\' argument to redirect test output to a file-like object (such as a StringIO, or opened file). Default is to write to sys.stdout. - conditionAsParseAction is a helper method for constructing a parse action method from a predicate function that simply returns a boolean result. Useful for those places where a predicate cannot be added using addCondition, but must be converted to a parse action (such as in infixNotation). May be used as a decorator if default message and exception types can be used. See ParserElement.addCondition for more details about the expected signature and behavior for predicate condition methods. - While investigating issue #93, I found that Or and addCondition could interact to select an alternative that is not the longest match. This is because Or first checks all alternatives for matches without running attached parse actions or conditions, orders by longest match, and then rechecks for matches with conditions and parse actions. Some expressions, when checking with conditions, may end up matching on a shorter token list than originally matched, but would be selected because of its original priority. This matching code has been expanded to do more extensive searching for matches when a second-pass check matches a smaller list than in the first pass. - Fixed issue #87, a regression in indented block. Reported by Renz Bagaporo, who submitted a very nice repro example, which makes the bug-fixing process a lot easier, thanks! - Fixed MemoryError issue #85 and #91 with str generation for Forwards. Thanks decalage2 and Harmon758 for your patience. - Modified setParseAction to accept None as an argument, indicating that all previously-defined parse actions for the expression should be cleared. - Modified pyparsing_common.real and sci_real to parse reals without leading integer digits before the decimal point, consistent with Python real number formats. Original PR #98 submitted by ansobolev. - Modified runTests to call postParse function before dumping out the parsed results - allows for postParse to add further results, such as indications of additional validation success/failure. - Updated statemachine example: refactored state transitions to use overridden classmethods; added Mixin class to simplify definition of application classes that \"own\" the state object and delegate to it to model state-specific properties and behavior. - Added example nested_markup.py, showing a simple wiki markup with nested markup directives, and illustrating the use of \'...\' for skipping over input to match the next expression. (This example uses syntax that is not valid under Python 2.) - Rewrote delta_time.py example (renamed from deltaTime.py) to fix some omitted formats and upgrade to latest pyparsing idioms, beginning with writing an actual BNF. - With the help and encouragement from several contributors, including Matěj Cepl and Cengiz Kaygusuz, I\'ve started cleaning up the internal coding styles in core pyparsing, bringing it up to modern coding practices from pyparsing\'s early development days dating back to 2003. Whitespace has been largely standardized along PEP8 guidelines, removing extra spaces around parentheses, and adding them around arithmetic operators and after colons and commas. I was going to hold off on doing this work until after 2.4.1, but after cleaning up a few trial classes, the difference was so significant that I continued on to the rest of the core code base. This should facilitate future work and submitted PRs, allowing them to focus on substantive code changes, and not get sidetracked by whitespace issues.
* Thu Apr 18 2019 mimi.vxAATTgmail.com- update to 2.4.0- drop nose_to_unittest.patch- drop _service
* Adds a pyparsing.__compat__ object for specifying compatibility with future breaking changes.
* Conditionalizes the API-breaking behavior, based on the value pyparsing.__compat__.collect_all_And_tokens. By default, this value will be set to True, reflecting the new bugfixed behavior.
* User code that is dependent on the pre-bugfix behavior can restore it by setting this value to False.
* Updated unitTests.py and simple_unit_tests.py to be compatible with \"python setup.py test\".
* Fixed bug in runTests handling \'\
\' literals in quoted strings.
* Added tag_body attribute to the start tag expressions generated by makeHTMLTags, so that you can avoid using SkipTo to roll your own tag body expression:
* indentedBlock failure handling was improved
* Address Py2 incompatibility in simpleUnitTests, plus explain() and Forward str() cleanup
* Fixed docstring with embedded \'\\w\', which creates SyntaxWarnings in Py3.8.
* Added example parser for rosettacode.org tutorial compiler.
* Added example to show how an HTML table can be parsed into a collection of Python lists or dicts, one per row.
* Updated SimpleSQL.py example to handle nested selects, reworked \'where\' expression to use infixNotation.
* Added include_preprocessor.py, similar to macroExpander.py.
* Examples using makeHTMLTags use new tag_body expression when retrieving a tag\'s body text.
* Updated examples that are runnable as unit tests
* Thu Apr 11 2019 tbechtoldAATTsuse.com- Do not BuildRequire python-unittest2 when no tests are executed. This breaks a build cycle for pyparsing->unittest2->traceback2->pbr-> Pygments->pytest->setuptools_scm->packaging which needs pyparsing
* Thu Jan 17 2019 dimstarAATTopensuse.org- BuildIgnore python[23]-pyparsing: python-packaging requires it for some actions it could perform, but we don\'t make use of these here. Ignoring this dependency allows us to break open a BuildCycle.

* Update CHANGES to include note on fixing issue #65; generalized the note about the decaf language example; added sample code from the statemachine examples.
* Unit test to test fix for issue #65
* Fix inconsistency between Keyword(caseless=True) and CaselessKeyword (issue #65)
* Fix typo: \'chemcialFormulas.py\' -> \'chemicalFormulas.py\'
* Convert exception logging to use ParseException.explain()
* Add experimental ParseException.explain() method, to return a multiline string showing the parse expressions leading to a parsing failure
* Clean up CHANGES notes for new examples
* Add document signoff and library book state examples;
* Update statemachine demo code to Py3
* Update Lucene grammar example, but remove from Travis-CI acceptance scripts
* Mon Jan 07 2019 mceplAATTsuse.com- Add nose_to_unittest.patch to avoid nose BR and rewrite tests to work (gh#pyparsing/pyparsing#64)
* Fri Dec 28 2018 mpluskalAATTsuse.com- Drop doc subpackage as it leads to circular dependencies on some releases
* Thu Nov 22 2018 jengelhAATTinai.de- Use more specific RPM group.

* Thu Nov 15 2018 tchvatalAATTsuse.com- Update to 2.3.0:
* Updates to migrate source repo to GitHub
* Fix deprecation warning in Python 3.7 re: importing collections.abc
* Fix Literal/Keyword bug raising IndexError instead of ParseException
* Added simple_unit_tests.py, as a collection of easy-to-follow unit
* tests for various classes and features of the pyparsing library.
* Primary intent is more to be instructional than actually rigorous
* testing. Complex tests can still be added in the unitTests.py file.
* New features added to the Regex class
* Thu Nov 15 2018 tchvatalAATTsuse.com- Fix URL to point to existing github
* Sat Aug 18 2018 mceplAATTsuse.com- Clean up SPEC file.
* Tue Mar 14 2017 dmuellerAATTsuse.com- update to 2.2.0: - Bumped minor version number to reflect compatibility issues with OneOrMore and ZeroOrMore bugfixes in 2.1.10. (2.1.10 fixed a bug that was introduced in 2.1.4, but the fix could break code written against 2.1.4 - 2.1.9.) - Updated setup.py to address recursive import problems now that pyparsing is part of \'packaging\' (used by setuptools). Patch submitted by Joshua Root, much thanks! - Fixed KeyError issue reported by Yann Bizeul when using packrat parsing in the Graphite time series database, thanks Yann! - Fixed incorrect usages of \'\\\' in literals, as described in https://docs.python.org/3/whatsnew/3.6.html#deprecated-python-behavior Patch submitted by Ville Skyttä - thanks! - Minor internal change when using \'-\' operator, to be compatible with ParserElement.streamline() method. - Expanded infixNotation to accept a list or tuple of parse actions to attach to an operation. - New unit test added for dill support for storing pyparsing parsers. Ordinary Python pickle can be used to pickle pyparsing parsers as long as they do not use any parse actions. The \'dill\' module is an extension to pickle which
*does
* support pickling of attached- drop desetuptoolize.patch: this is not needed
* Thu Feb 23 2017 jmatejekAATTsuse.com- update for single-spec- desetuptoolize.patch : switch from setuptools to distutils.core for installation, as this is now a setuptools dependency- ensure egg-info is a directory (distutils would install it as file)
* Fri Dec 02 2016 toddrme2178AATTgmail.com- Fix SLE 11 build.
* Tue Nov 01 2016 toddrme2178AATTgmail.com- update to version 2.1.10:
* Fixed bug in reporting named parse results for ZeroOrMore expressions, thanks Ethan Nash for reporting this!
* Fixed behavior of LineStart to be much more predictable. LineStart can now be used to detect if the next parse position is col 1, factoring in potential leading whitespace (which would cause LineStart to fail). Also fixed a bug in col, which is used in LineStart, where \'\
\'s were erroneously considered to be column 1.
* Added support for multiline test strings in runTests.
* Fixed bug in ParseResults.dump when keys were not strings. Also changed display of string values to show them in quotes, to help distinguish parsed numeric strings from parsed integers that have been converted to Python ints.- update to version 2.1.9:
* Added class CloseMatch, a variation on Literal which matches \"close\" matches, that is, strings with at most \'n\' mismatching characters.
* Fixed bug in Keyword.setDefaultKeywordChars(), reported by Kobayashi Shinji - nice catch, thanks!
* Minor API change in pyparsing_common. Renamed some of the common expressions to PEP8 format (to be consistent with the other pyparsing_common expressions): + signedInteger -> signed_integer + sciReal -> sci_real Also, in trying to stem the API bloat of pyparsing, I\'ve copied some of the global expressions and helper parse actions into pyparsing_common, with the originals to be deprecated and removed in a future release: + commaSeparatedList -> pyparsing_common.comma_separated_list + upcaseTokens -> pyparsing_common.upcaseTokens + downcaseTokens -> pyparsing_common.downcaseTokens
* Fixed Python3 compatibility bug when using dict keys() and values() in ParseResults.getName().
* After some prodding, I\'ve reworked the unitTests.py file for pyparsing over the past few releases. It uses some variations on unittest to handle my testing style. The test now: + auto-discovers its test classes (while maintining their order of definition) + suppresses voluminous \'print\' output for tests that pass- update to version 2.1.8:
* Fixed issue in the optimization to _trim_arity, when the full stacktrace is retrieved to determine if a TypeError is raised in pyparsing or in the caller\'s parse action. Code was traversing the full stacktrace, and potentially encountering UnicodeDecodeError.
* Fixed bug in ParserElement.inlineLiteralsUsing, causing infinite loop with Suppress.
* Fixed bug in Each, when merging named results from multiple expressions in a ZeroOrMore or OneOrMore. Also fixed bug when ZeroOrMore expressions were erroneously treated as required expressions in an Each expression.
* Added a few more inline doc examples.
* Improved use of runTests in several example scripts.- changes from version 2.1.7:
* Fixed regression reported by Andrea Censi (surfaced in PyContracts tests) when using ParseSyntaxExceptions (raised when using operator \'-\') with packrat parsing.
* Minor fix to oneOf, to accept all iterables, not just space-delimited strings and lists. (If you have a list or set of strings, it is not necessary to concat them using \' \'.join to pass them to oneOf, oneOf will accept the list or set or generator directly.)- changes from version 2.1.6 :
*
*Major packrat upgrade
*, inspired by patch provided by Tal Einat - many, many, thanks to Tal for working on this! Tal\'s tests show faster parsing performance (2X in some tests),
*and
* memory reduction from 3GB down to ~100MB! Requires no changes to existing code using packratting. (Uses OrderedDict, available in Python 2.7 and later. For Python 2.6 users, will attempt to import from ordereddict backport. If not present, will implement pure-Python Fifo dict.)
* Minor API change - to better distinguish between the flexible numeric types defined in pyparsing_common, I\'ve changed \"numeric\" (which parsed numbers of different types and returned int for ints, float for floats, etc.) and \"number\" (which parsed numbers of int or float type, and returned all floats) to \"number\" and \"fnumber\" respectively. I hope the \"f\" prefix of \"fnumber\" will be a better indicator of its internal conversion of parsed values to floats, while the generic \"number\" is similar to the flexible number syntax in other languages. Also fixed a bug in pyparsing_common.numeric (now renamed to pyparsing_common.number), integers were parsed and returned as floats instead of being retained as ints.
* Fixed bug in upcaseTokens and downcaseTokens introduced in 2.1.5, when the parse action was used in conjunction with results names. Reported by Steven Arcangeli from the dql project, thanks for your patience, Steven!
* Major change to docs! After seeing some comments on reddit about general issue with docs of Python modules, and thinking that I\'m a little overdue in doing some doc tuneup on pyparsing, I decided to following the suggestions of the redditor and add more inline examples to the pyparsing reference documentation. I hope this addition will clarify some of the more common questions people have, especially when first starting with pyparsing/Python.
* Deprecated ParseResults.asXML. I\'ve never been too happy with this method, and it usually forces some unnatural code in the parsers in order to get decent tag names. The amount of guesswork that asXML has to do to try to match names with values should have been a red flag from day one. If you are using asXML, you will need to implement your own ParseResults->XML serialization. Or consider migrating to a more current format such as JSON (which is very easy to do: results_as_json = json.dumps(parse_result.asDict()) Hopefully, when I remove this code in a future version, I\'ll also be able to simplify some of the craziness in ParseResults, which IIRC was only there to try to make asXML work.
* Updated traceParseAction parse action decorator to show the repr of the input and output tokens, instead of the str format, since str has been simplified to just show the token list content.- update to version 2.1.5:
* Added ParserElement.split() generator method, similar to re.split(). Includes optional arguments maxsplit (to limit the number of splits), and includeSeparators (to include the separating matched text in the returned output, default=False).
* Added a new parse action construction helper tokenMap, which will apply a function and optional arguments to each element in a ParseResults.
* Added more expressions to pyparsing_common: + IPv4 and IPv6 addresses (including long, short, and mixed forms of IPv6) + MAC address + ISO8601 date and date time strings (with named fields for year, month, etc.) + UUID (xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx) + hex integer (returned as int) + fraction (integer \'/\' integer, returned as float) + mixed integer (integer \'-\' fraction, or just fraction, returned as float) + stripHTMLTags (parse action to remove tags from HTML source) + parse action helpers convertToDate and convertToDatetime to do custom parse time conversions of parsed ISO8601 strings
* runTests now returns a two-tuple: success if all tests succeed, and an output list of each test and its output lines.
* Added failureTests argument (default=False) to runTests, so that tests can be run that are expected failures, and runTests\' success value will return True only if all tests
*fail
* as expected. Also, parseAll now defaults to True.
* New example numerics.py, shows samples of parsing integer and real numbers using locale-dependent formats- changes from version 2.1.4:
* Split out the \'==\' behavior in ParserElement, now implemented as the ParserElement.matches() method. Using \'==\' for string test purposes will be removed in a future release.
* Expanded capabilities of runTests(). Will now accept embedded comments (default is Python style, leading \'#\' character, but customizable). Comments will be emitted along with the tests and test output. Useful during test development, to create a test string consisting only of test case description comments separated by blank lines, and then fill in the test cases. Will also highlight ParseFatalExceptions with \"(FATAL)\".
* Added a \'pyparsing_common\' class containing common/helpful little expressions such as integer, float, identifier, etc. I used this class as a sort of embedded namespace, to contain these helpers without further adding to pyparsing\'s namespace bloat.
* Minor enhancement to traceParseAction decorator, to retain the parse action\'s name for the trace output.
* Added optional \'fatal\' keyword arg to addCondition, to indicate that a condition failure should halt parsing immediately.- changes from version 2.1.3:
* _trim_arity fix in 2.1.2 was very version-dependent on Py 3.5.0. Now works for Python 2.x, 3.3, 3.4, 3.5.0, and 3.5.1 (and hopefully beyond).- changes from version 2.1.2:
* Fixed bug in _trim_arity when pyparsing code is included in a PyInstaller, reported by maluwa.
* Fixed catastrophic regex backtracking in implementation of the quoted string expressions (dblQuotedString, sglQuotedString, and quotedString). Reported on the pyparsing wiki by webpentest, good catch! (Also tuned up some other expressions susceptible to the same backtracking problem, such as cStyleComment, cppStyleComment, etc.)- update to version 2.1.1:
* Added support for assigning to ParseResults using slices.
* Fixed bug in ParseResults.toDict(), in which dict values were always converted to dicts, even if they were just unkeyed lists of tokens. Reported on SO by Gerald Thibault, thanks Gerald!
* Fixed bug in SkipTo when using failOn, reported by robyschek, thanks!
* Fixed bug in Each introduced in 2.1.0, reported by AND patch and unit test submitted by robyschek, well done!
* Removed use of functools.partial in replaceWith, as this creates an ambiguous signature for the generated parse action, which fails in PyPy. Reported by Evan Hubinger, thanks Evan!
* Added default behavior to QuotedString to convert embedded \'\\t\', \'\
\', etc. characters to their whitespace counterparts. Found during Q&A exchange on SO with Maxim.- update to version 2.1.0:
* Modified the internal _trim_arity method to distinguish between TypeError\'s raised while trying to determine parse action arity and those raised within the parse action itself. This will clear up those confusing \"() takes exactly 1 argument (0 given)\" error messages when there is an actual TypeError in the body of the parse action. Thanks to all who have raised this issue in the past, and most recently to Michael Cohen, who sent in a proposed patch, and got me to finally tackle this problem.
* Added compatibility for pickle protocols 2-4 when pickling ParseResults. In Python 2.x, protocol 0 was the default, and protocol 2 did not work. In Python 3.x, protocol 3 is the default, so explicitly naming protocol 0 or 1 was required to pickle ParseResults. With this release, all protocols 0-4 are supported. Thanks for reporting this on StackOverflow, Arne Wolframm, and for providing a nice simple test case!
* Added optional \'stopOn\' argument to ZeroOrMore and OneOrMore, to simplify breaking on stop tokens that would match the repetition expression. It is a common problem to fail to look ahead when matching repetitive tokens if the sentinel at the end also matches the repetition expression, as when parsing \"BEGIN aaa bbb ccc END\" with: \"BEGIN\" + OneOrMore(Word(alphas)) + \"END\" Since \"END\" matches the repetition expression \"Word(alphas)\", it will never get parsed as the terminating sentinel. Up until now, this has to be resolved by the user inserting their own negative lookahead: \"BEGIN\" + OneOrMore(~Literal(\"END\") + Word(alphas)) + \"END\" Using stopOn, they can more easily write: \"BEGIN\" + OneOrMore(Word(alphas), stopOn=\"END\") + \"END\" The stopOn argument can be a literal string or a pyparsing expression. Inspired by a question by Lamakaha on StackOverflow (and many previous questions with the same negative-lookahead resolution).
* Added expression names for many internal and builtin expressions, to reduce name and error message overhead during parsing.
* Converted helper lambdas to functions to refactor and add docstring support.
* Fixed ParseResults.asDict() to correctly convert nested ParseResults values to dicts.
* Cleaned up some examples, fixed typo in fourFn.py identified by aristotle2600 on reddit.
* Removed keepOriginalText helper method, which was deprecated ages ago. Superceded by originalTextFor.
* Same for the Upcase class, which was long ago deprecated and replaced with the upcaseTokens method.
* Mon Feb 01 2016 toddrme2178AATTgmail.com- update to version 2.0.7:
* Simplified string representation of Forward class, to avoid memory and performance errors while building ParseException messages. Thanks, Will McGugan, Andrea Censi, and Martijn Vermaat for the bug reports and test code.
* Cleaned up additional issues from enhancing the error messages for Or and MatchFirst, handling Unicode values in expressions. Fixes Unicode encoding issues in Python 2, thanks to Evan Hubinger for the bug report.
* Fixed implementation of dir() for ParseResults - was leaving out all the defined methods and just adding the custom results names.
* Fixed bug in ignore() that was introduced in pyparsing 1.5.3, that would not accept a string literal as the ignore expression.
* Added new example parseTabularData.py to illustrate parsing of data formatted in columns, with detection of empty cells.
* Updated a number of examples to more current Python and pyparsing forms.- update to version 2.0.6:
* Fixed a bug in Each when multiple Optional elements are present. Thanks for reporting this, whereswalden on SO.
* Fixed another bug in Each, when Optional elements have results names or parse actions, reported by Max Rothman - thank you, Max!
* Added optional parseAll argument to runTests, whether tests should require the entire input string to be parsed or not (similar to parseAll argument to parseString). Plus a little neaten-up of the output on Python 2 (no stray ()\'s).
* Modified exception messages from MatchFirst and Or expressions. These were formerly misleading as they would only give the first or longest exception mismatch error message. Now the error message includes all the alternatives that were possible matches. Originally proposed by a pyparsing user, but I\'ve lost the email thread - finally figured out a fairly clean way to do this.
* Fixed a bug in Or, when a parse action on an alternative raises an exception, other potentially matching alternatives were not always tried. Reported by TheVeryOmni on the pyparsing wiki, thanks!
* Fixed a bug to dump() introduced in 2.0.4, where list values were shown in duplicate.- update to version 2.0.5:
* (&$(AATT#&$(AATT!!!! Some \"print\" statements snuck into pyparsing v2.0.4, breaking Python 3 compatibility! Fixed. Reported by jenshn, thanks!- changes from Version 2.0.4:
* Added ParserElement.addCondition, to simplify adding parse actions that act primarily as filters. If the given condition evaluates False, pyparsing will raise a ParseException. The condition should be a method with the same method signature as a parse action, but should return a boolean. Suggested by Victor Porton, nice idea Victor, thanks!
* Slight mod to srange to accept unicode literals for the input string, such as \"[а-яА-Я]\" instead of \"[\\u0430-\\u044f\\u0410-\\u042f]\". Thanks to Alexandr Suchkov for the patch!
* Enhanced implementation of replaceWith.
* Fixed enhanced ParseResults.dump() method when the results consists only of an unnamed array of sub-structure results. Reported by Robin Siebler, thanks for your patience and persistence, Robin!
* Fixed bug in fourFn.py example code, where pi and e were defined using CaselessLiteral instead of CaselessKeyword. This was not a problem until adding a new function \'exp\', and the leading \'e\' of \'exp\' was accidentally parsed as the mathematical constant \'e\'. Nice catch, Tom Grydeland - thanks!
* Adopt new-fangled Python features, like decorators and ternary expressions, per suggestions from Williamzjc - thanks William! (Oh yeah, I\'m not supporting Python 2.3 with this code any more...) Plus, some additional code fixes/cleanup - thanks again!
* Added ParserElement.runTests, a little test bench for quickly running an expression against a list of sample input strings. Basically, I got tired of writing the same test code over and over, and finally added it as a test point method on ParserElement.
* Added withClass helper method, a simplified version of withAttribute for the common but annoying case when defining a filter on a div\'s class - made difficult because \'class\' is a Python reserved word.
* Mon May 11 2015 benoit.moninAATTgmx.fr- update to version 2.0.3:
* Fixed escaping behavior in QuotedString. Formerly, only quotation marks (or characters designated as quotation marks in the QuotedString constructor) would be escaped. Now all escaped characters will be escaped, and the escaping backslashes will be removed.
* Fixed regression in ParseResults.pop() - pop() was pretty much broken after I added
*improvements
* in 2.0.2. Reported by Iain Shelvington, thanks Iain!
* Fixed bug in And class when initializing using a generator.
* Enhanced ParseResults.dump() method to list out nested ParseResults that are unnamed arrays of sub-structures.
* Fixed UnboundLocalError under Python 3.4 in oneOf method, reported on Sourceforge by aldanor, thanks!
* Fixed bug in ParseResults __init__ method, when returning non-ParseResults types from parse actions that implement __eq__. Raised during discussion on the pyparsing wiki with cyrfer.- fix end of line encoding of every file in examples
* Tue Nov 11 2014 Greg.FreemyerAATTgmail.com- update to v2.0.2 - Extended \"expr(name)\" shortcut (same as \"expr.setResultsName(name)\") to accept \"expr()\" as a shortcut for \"expr.copy()\". - Added \"locatedExpr(expr)\" helper, to decorate any returned tokens with their location within the input string. Adds the results names locn_start and locn_end to the output parse results. - Added \"pprint()\" method to ParseResults, to simplify troubleshooting and prettified output. Now instead of importing the pprint module and then writing \"pprint.pprint(result)\", you can just write \"result.pprint()\". This method also accepts addtional positional and keyword arguments (such as indent, width, etc.), which get passed through directly to the pprint method (see http://docs.python.org/2/library/pprint.html#pprint.pprint). - Removed deprecation warnings when using \'<<\' for Forward expression assignment. \'<<=\' is still preferred, but \'<<\' will be retained for cases whre \'<<=\' operator is not suitable (such as in defining lambda expressions). - Expanded argument compatibility for classes and functions that take list arguments, to now accept generators as well. - Extended list-like behavior of ParseResults, adding support for append and extend. NOTE: if you have existing applications using these names as results names, you will have to access them using dict-style syntax: res[\"append\"] and res[\"extend\"] - ParseResults emulates the change in list vs. iterator semantics for methods like keys(), values(), and items(). Under Python 2.x, these methods will return lists, under Python 3.x, these methods will return iterators. - ParseResults now has a method haskeys() which returns True or False depending on whether any results names have been defined. This simplifies testing for the existence of results names under Python 3.x, which returns keys() as an iterator, not a list. - ParseResults now supports both list and dict semantics for pop(). If passed no argument or an integer argument, it will use list semantics and pop tokens from the list of parsed tokens. If passed a non-integer argument (most likely a string), it will use dict semantics and pop the corresponding value from any defined results names. A second default return value argument is supported, just as in dict.pop(). - Fixed bug in markInputline, thanks for reporting this, Matt Grant! - Cleaned up my unit test environment, now runs with Python 2.6 and 3.3.
* Mon Sep 23 2013 hpjAATTurpla.net- include examples in -doc package
* Tue Sep 17 2013 speilickeAATTsuse.com- Update to version 2.0.1: - Removed use of \"nonlocal\" that prevented using this version of pyparsing with Python 2.6 and 2.7. This will make it easier to install for packages that depend on pyparsing, under Python versions 2.6 and later. Those using older versions of Python will have to manually install pyparsing 1.5.7. - Fixed implementation of <<= operator to return self; reported by Luc J. Bourhis, with patch fix by Mathias Mamsch - thanks, Luc and Mathias!- Changes from version 2.0.0: - Rather than release another combined Python 2.x/3.x release I\'ve decided to start a new major version that is only compatible with Python 3.x (and consequently Python 2.7 as well due to backporting of key features). This version will be the main development path from now on, with little follow-on development on the 1.5.x path. - Operator \'<<\' is now deprecated, in favor of operator \'<<=\' for attaching parsing expressions to Forward() expressions. This is being done to address precedence of operations problems with \'<<\'. Operator \'<<\' will be removed in a future version of pyparsing.
* Tue Sep 17 2013 dmuellerAATTsuse.com- remove nonsensical tarball
* Wed Mar 13 2013 dmuellerAATTsuse.com- update to 1.5.7:
* NOTE: This is the last release of pyparsing that will try to maintain compatibility with Python versions < 2.6. The next release of pyparsing will be version 2.0.0, using new Python syntax that will not be compatible for Python version 2.5 or older.
* An awesome new example is included in this release, submitted by Luca DellOlio, for parsing ANTLR grammar definitions, nice work Luca!
* Fixed implementation of ParseResults.__str__ to use Pythonic \'\'.join() instead of repeated string concatenation. This purportedly has been a performance issue under PyPy.
* Fixed bug in ParseResults.__dir__ under Python 3, reported by Thomas Kluyver, thank you Thomas!
* Added ParserElement.inlineLiteralsUsing static method, to override pyparsing\'s default behavior of converting string literals to Literal instances, to use other classes (such as Suppress or CaselessLiteral).
* Added new operator \'<<=\', which will eventually replace \'<<\' for storing the contents of a Forward(). \'<<=\' does not have the same operator precedence problems that \'<<\' does.
* \'operatorPrecedence\' is being renamed \'infixNotation\' as a better description of what this helper function creates. \'operatorPrecedence\' is deprecated, and will be dropped entirely in a future release.
* Added optional arguments lpar and rpar to operatorPrecedence, so that expressions that use it can override the default suppression of the grouping characters.
* Added support for using single argument builtin functions as parse actions. Now you can write \'expr.setParseAction(len)\' and get back the length of the list of matched tokens. Supported builtins are: sum, len, sorted, reversed, list, tuple, set, any, all, min, and max. A script demonstrating this feature is included in the examples directory.
* Fixed a bug in the definition of \'alphas\', which was based on the string.uppercase and string.lowercase \"constants\", which in fact
* aren\'t
* constant, but vary with locale settings. This could make parsers locale-sensitive in a subtle way. Thanks to Kef Schecter for his diligence in following through on reporting and monitoring this bugfix!
* Fixed a bug in the Py3 version of pyparsing, during exception handling with packrat parsing enabled, reported by Catherine Devlin - thanks Catherine!
* Fixed typo in ParseBaseException.__dir__, reported anonymously on the SourceForge bug tracker, thank you Pyparsing User With No Name.
* Fixed bug in srange when using \'\\x###\' hex character codes.
* Addeed optional \'intExpr\' argument to countedArray, so that you can define your own expression that will evaluate to an integer, to be used as the count for the following elements. Allows you to define a countedArray with the count given in hex, for example, by defining intExpr as \"Word(hexnums).setParseAction(int(t[0],16))\".
* Mon Jan 14 2013 saschpeAATTsuse.de- Fix license (MIT and GPL-2.0+ and GPL-3.0+)
* Wed Jan 09 2013 saschpeAATTsuse.de- Don\'t ship examples twice
* Mon Jan 07 2013 p.drouandAATTgmail.com- Initial support of python3
* Fri Nov 23 2012 saschpeAATTsuse.de- Package examples- Spec file cleanup
* Sun Jul 03 2011 saschpeAATTgmx.de- Add Provides/Obsoletes for python-parsing
* Thu Jun 30 2011 saschpeAATTsuse.de- Update to version 1.5.6:
* Cleanup of parse action normalizing code, to be more version-tolerant, and robust in the face of future Python versions
* Removal of exception cacheing, addressing a memory leak condition in Python 3.
* Fixed bug when using packrat parsing, where a previously parsed expression would duplicate subsequent tokens
* Fixed bug in srange, which accepted escaped hex characters of the form \'\\0x##\', but should be \'\\x##\'. Both forms will be supported for backwards compatibility.
* Added the Verilog parser to the provided set of examples, under the MIT license.
* Added the excludeChars argument to the Word class, to simplify defining a word composed of all characters in a large range except for one or two.
* Added optional overlap parameter to scanString, to return overlapping matches found in the source text.
* Updated oneOf internal regular expression generation, with improved parse time performance.
* Slight performance improvement in transformString, removing empty strings from the list of string fragments built while scanning the source text, before calling \'\'.join. Especially useful when using transformString to strip out selected text.
* Enhanced form of using the \"expr(\'name\')\" style of results naming, in lieu of calling setResultsName. If name ends with an \'
*\', then this is equivalent to expr.setResultsName(\'name\',listAllMatches=True).
* Fixed up internal list flattener to use iteration instead of recursion, to avoid stack overflow when transforming large files.- Changes from version 1.5.5:
* Typo in Python3 version of pyparsing, \"builtin\" should be \"builtins\".- Changes from version 1.5.4:
* Fixed __builtins__ and file references in Python 3 code, thanks to Greg Watson, saulspatz, sminos, and Mark Summerfield for reporting their Python 3 experiences.- Spec file cleanup:
* Regenerated with py2pack, much simpler spec file
* Fixed license to MIT, it\'s not GPLv2+
* Wed Jul 07 2010 pascal.bleserAATTopensuse.org- Initial package (1.5.3)
