[Python-announce] TatSu 5.13.0

From =?UTF-8?Q?Juancarlo_A=C3=B1ez?=@[email protected] to comp.lang.python.announce on Tue Jan 7 10:32:11 2025

From Newsgroup: comp.lang.python.announce

竜 TatSu is a tool that takes grammars in a variation of EBNF as input, and outputs memoizing (Packrat) PEG parsers in Python.

In this release:

- remove comments_re and eol_comments_re from parser configuration
(ParserConfig). Use comments and/or eol_comments instead (#351)
- do not apply re.MULTILINE to compiled regexes. Users must add (?m) to
the expressions for multiline (#351)
- cache compiled regexes for performance
- fix bug in positive joins (#342)
- test with Python 3.13 and latest libraries
