-- reverted REPEAT operator to use "repeat context" strategy
(from 0.8.X), but done right this time.
-- got rid of backtracking stack; use nested SRE_MATCH calls
instead (should probably put it back again in 0.9.9 ;-)
-- properly reset state in scanner mode
-- don't use aggressive inlining by default
+ added "regs" attribute
+ fixed "pos" and "endpos" attributes
+ reset "lastindex" and "lastgroup" in scanner methods
+ removed (?P#id) syntax; the "lastindex" and "lastgroup"
attributes are now always set
+ removed string module dependencies in sre_parse
+ better debugging support in sre_parse
+ various tweaks to build under 1.5.2
the pattern must have a fixed width.
- got rid of array-module dependencies; the match pro-
gram is now stored inside the pattern object, rather
than in an extra string buffer.
- cleaned up a various of potential leaks, api abuses,
and other minors in the engine module.
- use mal's new isalnum macro, rather than my own work-
around.
- untabified test_sre.py. seems like I removed a couple
of trailing spaces in the process...
"lastgroup" is the name of the last matched capturing group,
"lastindex" is the index of the same group. if no group was
matched, both attributes are set to None.
the (?P#) feature will be removed in the next relase.
used by the code generator)
- changed max repeat value in engine (to match earlier array fix)
- added experimental "which part matched?" mechanism to sre; see
http://hem.passagen.se/eff/2000_07_01_bot-archive.htm#416954
or python-dev for details.
speedup for some tests, including the python tokenizer.
-- added support for an optional charset anchor to the engine
(currently unused by the code generator).
-- removed workaround for array module bug.
-- changed 1.6 to 2.0 in the file headers
-- fixed ISALNUM macro for the unicode locale. this
solution isn't perfect, but the best I can do with
Python's current unicode database.
-- added pickling support (only works if sre is imported)
-- fixed wordsize problems in engine
(instead of casting literals down to the character size,
cast characters up to the literal size (same as the code
word size). this prevents false hits when you're matching
a unicode pattern against an 8-bit string. (unfortunately,
this broke another test, but I think the test should be
changed in this case; more on that on python-dev)
-- added sre.purge function
(unofficial, clears the cache)
(those semantics are weird...)
- got rid of $Id$'s (for the moment, at least). in other
words, there should be no more "empty" checkins.
- internal: some minor cleanups.
tests in sre_patch back to previous version
- fixed return value from findall
- renamed a bunch of functions inside _sre (way too
many leading underscores...)
