- Split primary flavor in multibuild for possible inclusion into
Ring0
- Update to version 3.0.9
* Added Unicode set BasicMultilingualPlane (may also be
referenced as BMP) representing the Basic Multilingual Plane
(Unicode characters up to code point 65535). Can be used to
parse most language characters, but omits emojis, wingdings,
etc. Raised in discussion with Dave Tapley (issue #392).
* To address mypy confusion of pyparsing.Optional and
typing.Optional resulting in error: "_SpecialForm" not callable
message reported in issue #365, fixed the import in
exceptions.py. Nice sleuthing by Iwan Aucamp and Dominic
Davis-Foster, thank you! (Removed definitions of OptionalType,
DictType, and IterableType and replaced them with
typing.Optional, typing.Dict, and typing.Iterable throughout.)
* Fixed typo in jinja2 template for railroad diagrams, thanks for
the catch Nioub (issue #388).
* Removed use of deprecated pkg_resources package in railroad
diagramming code (issue #391).
* Updated bigquery_view_parser.py example to parse examples at
https://cloud.google.com/bigquery/docs/reference/legacy-sql
- Release 3.0.8
* API CHANGE: modified pyproject.toml to require Python version
3.6.8 or later for pyparsing 3.x. Earlier minor versions of 3.6
fail in evaluating the version_info class (implemented using
typing.NamedTuple). If you are using an earlier version of
Python 3.6, you will need to use pyparsing 2.4.7.
* Improved pyparsing import time by deferring regex pattern
compiles. PR submitted by Anthony Sottile to fix issue #362,
thanks!
* Updated build to use flit, PR by Michał Górny, added
BUILDING.md doc and removed old Windows build scripts - nice
cleanup work!
* More type-hinting added for all arithmetic and logical operator
methods in ParserElement. PR from Kazantcev Andrey, thank you.
* Fixed infix_notation's definitions of lpar and rpar, to accept
parse expressions such that they do not get suppressed in the
parsed results. PR submitted by Philippe Prados, nice work.
* Fixed bug in railroad diagramming with expressions containing
Combine elements. Reported by Jeremy White, thanks!
* Added show_groups argument to create_diagram to highlight
grouped elements with an unlabeled bounding box.
* Added unicode_denormalizer.py to the examples as a
demonstration of how Python's interpreter will accept Unicode
characters in identifiers, but normalizes them back to ASCII so
that identifiers print and 𝕡𝓻ᵢ𝓃𝘁 and 𝖕𝒓𝗂𝑛ᵗ are all
equivalent.
* Removed imports of deprecated sre_constants module for catching
exceptions when compiling regular expressions. PR submitted by
Serhiy Storchaka, thank you.
- Use python-base bundled pip as frontend for flit-core
- specfile:
* update copyright year
- update to version 3.0.7:
* Fixed bug #345, in which delimitedList changed expressions in
place using expr.streamline(). Reported by Kim Gräsman, thanks!
* Fixed bug #346, when a string of word characters was passed to
WordStart or WordEnd instead of just taking the default
value. Originally posted as a question by Parag on StackOverflow,
good catch!
* Fixed bug #350, in which White expressions could fail to match due
to unintended whitespace-skipping. Reported by Fu Hanxi, thank
you!
* Fixed bug #355, when a QuotedString is defined with characters in
its quoteChar string containing regex-significant characters such
as ., *, ?, [, ], etc.
* Fixed bug in ParserElement.run_tests where comments would be
displayed using with_line_numbers.
* Added optional "min" and "max" arguments to `delimited_list`. PR
submitted by Marius, thanks!
* Added new API change note in `whats_new_in_pyparsing_3_0_0`,
regarding a bug fix in the `bool()` behavior of `ParseResults`.
* Prior to pyparsing 3.0.x, the `ParseResults` class implementation
of `__bool__` would return `False` if the `ParseResults` item list
was empty, even if it contained named results. In 3.0.0 and later,
`ParseResults` will return `True` if either the item list is not
empty *or* if the named results dict is not empty.
* Minor enhancement to Word generation of internal regular
expression, to emit consecutive characters in range, such as "ab",
as "ab", not "a-b".
* Fixed character ranges for search terms using non-Western
characters in booleansearchparser, PR submitted by tc-yu, nice
work!
* Additional type annotations on public methods.
- requires jinja2 for testing
- requires railroad-diagrams for testing
- update to 3.0.6:
* Added suppress_warning() method to individually suppress a warning
on a specific ParserElement. Used to refactor original_text_for
to preserve internal results names, which, while undocumented, had
been adopted by some projects.
* Fix bug when delimited_list was called with a str literal instead
of a parse expression.
- changes from 3.0.5:
* Added return type annotations for col, line, and lineno.
* Fixed bug when warn_ungrouped_named_tokens_in_collection warning
was raised when assigning a results name to an original_text_for
expression. (Issue #110, would raise warning in packaging.)
* Fixed internal bug where ParserElement.streamline() would not
return self if already streamlined.
* Changed run_tests() output to default to not showing line and
column numbers. If line numbering is desired, call with
with_line_numbers=True. Also fixed minor bug where separating
line was not included after a test failure.
- changes from 3.0.4:
* Fixed bug in which Dict classes did not correctly return tokens
as nested ParseResults
* Documented API-changing side-effect of converting ParseResults
to use __slots__ to pre-define instance attributes.
* Fixed bug in railroad diagramming where the vertical limit would
count all expressions in a group, not just those that would
create visible railroad elements.
- changes from 3.0.3:
* Fixed regex typo in one_of fix for as_keyword=True.
* Fixed a whitespace-skipping bug, Issue #319, introduced as part
of the revert of the LineStart changes.
* Added header column labeling > 100 in with_line_numbers - some
input lines are longer than others.
- changes from 3.0.2:
* Reverted change in behavior with LineStart and StringStart, which
changed the interpretation of when and how LineStart and
StringStart should match when a line starts with spaces. In 3.0.0,
the xxxStart expressions were not really treated like expressions
in their own right, but as modifiers to the following expression
when used like LineStart() + expr, so that if there were whitespace
on the line before expr (which would match in versions prior to
3.0.0), the match would fail.
3.0.0 implemented this by automatically promoting LineStart() +
expr to AtLineStart(expr), which broke existing parsers that did
not expect expr to necessarily be right at the start of the line,
but only be the first token found on the line. This was reported
as a regression in Issue (gh#pyparsing/pyparsing/issues#317).
In 3.0.2, pyparsing reverts to the previous behavior, but will
retain the new AtLineStart and AtStringStart expression classes,
so that parsers can chose whichever behavior applies in their
specific instance.
* Performance enhancement to one_of to always generate an internal
Regex, even if caseless or as_keyword args are given as True
(unless explicitly disabled by passing use_regex=False).
* IndentedBlock class now works with recursive flag. By default,
the results parsed by an IndentedBlock are grouped. This can be
disabled by constructing the IndentedBlock with grouped=False.
- changes from 3.0.1
* Fixed bug where Word(max=n) did not match word groups less than
length 'n'. Thanks to Joachim Metz for catching this!
* Fixed bug where ParseResults accidentally created recursive
contents. Joachim Metz on this one also!
* Fixed bug where warn_on_multiple_string_args_to_oneof warning
is raised even when not enabled.
- changes from 3.0.0
* A consolidated list of all the changes in the 3.0.0 release
can be found in docs/whats_new_in_3_0_0.rst.
(https://github.com/pyparsing/pyparsing/blob/master/docs/whats_new_in_3_0_0.rst)

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
- Do not pull in setuptools dependency at all to avoid cycles
- 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.
- 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
- 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 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)
- Drop doc subpackage as it leads to circular dependencies on some
releases
- Use more specific RPM group.
- Upgrade to the current upstrem master with additional patches
to make the test suite pass.
- Add all tests.
- 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
- Fix URL to point to existing github
- Clean up SPEC file.
- 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
- 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)
- Fix SLE 11 build.
- 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.
- 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
- 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.
- include examples in -doc package
- 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.
- remove nonsensical tarball
- 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))".
- Fix license (MIT and GPL-2.0+ and GPL-3.0+)
- Don't ship examples twice
- Initial support of python3
- Package examples
- Spec file cleanup
- Add Provides/Obsoletes for python-parsing
- 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+
- Initial package (1.5.3)
