Tue Aug 6 05:01:32 UTC 2019 - Thomas Bechtold <tbechtold@suse.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 <statename>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 13:30:30 UTC 2019 - Ondřej Súkup <mimi.vx@gmail.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 '\n' 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

|
||
|
||
- 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 15:54:39 UTC 2019 - Dominique Leuenberger <dimstar@opensuse.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.

||
-------------------------------------------------------------------
|
||
Tue Jan 08 19:10:15 UTC 2019 - opensuse-packaging@opensuse.org
|
||
|
||
- Update to version 2.3.0+git.1546912853.bf348d6:
|
||
* 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

- Add nose_to_unittest.patch to avoid nose BR and rewrite tests
|
||
to work (gh#pyparsing/pyparsing#64)
|

-------------------------------------------------------------------
|
||
Fri Dec 28 09:57:56 UTC 2018 - Martin Pluskal <mpluskal@suse.com>

|
||
Thu Nov 15 08:46:10 UTC 2018 - Tomáš Chvátal <tchvatal@suse.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.
|

-------------------------------------------------------------------
|
||
Tue Mar 14 21:27:44 UTC 2017 - dmueller@suse.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 11:45:52 UTC 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 2 16:32:17 UTC 2016 - toddrme2178@gmail.com
|
||
|
||
- Fix SLE 11 build.
|
||
|
||
-------------------------------------------------------------------
|
||
Tue Nov 1 19:46:14 UTC 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.

|
||
|
||
- 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 17:40:24 UTC 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 17:34:18 UTC 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.

Tue Sep 17 13:15:51 UTC 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.

|
||
Wed Mar 13 09:04:46 UTC 2013 - dmueller@suse.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))".

-------------------------------------------------------------------
|
||
Thu Jun 30 08:33:22 UTC 2011 - saschpe@suse.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+
