Version 2.4.0:
- Well, it looks like the API change that was introduced in 2.3.1 was more
drastic than expected, so for a friendlier forward upgrade path, this
release:
. Bumps the current version number to 2.4.0, to reflect this
incompatible change.
. 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. To set this
value to False, add to your code:
import pyparsing
pyparsing.__compat__.collect_all_And_tokens = False
. User code that is dependent on the pre-bugfix behavior can restore
it by setting this value to False.
In 2.5 and later versions, the conditional code will be removed and
setting the flag to True or False in these later versions will have no
effect.
- Updated unitTests.py and simple_unit_tests.py to be compatible with
"python setup.py test". To run tests using setup, do:
python setup.py test
python setup.py test -s unitTests.suite
python setup.py test -s simple_unit_tests.suite
- 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:
a, aEnd = pp.makeHTMLTags('a')
link = a + a.tag_body("displayed_text") + aEnd
for t in s.searchString(html_page):
print(t.displayed_text, '->', t.startA.href)
- 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.
- Examples:
- 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:
python setup.py test -s examples.antlr_grammar_tests
python setup.py test -s examples.test_bibparse
