- 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.
