| Summary: Grammar Parser Library for Python | |
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. The pyparsing module provides a library of classes that client code uses to construct the grammar directly in Python code.

- 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 jmatejek@suse.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 toddrme2178@gmail.com
- Fix SLE 11 build.
* Tue Nov 01 2016 toddrme2178@gmail.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 '\n'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',
'\n', 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 "<lambda>() 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 toddrme2178@gmail.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:
* (&$(@#&$(@!!!! 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.monin@gmx.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.Freemyer@gmail.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 hpj@urpla.net
- include examples in -doc package
* Tue Sep 17 2013 speilicke@suse.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 dmueller@suse.com
