Fredrik Lundh 72b82ba16d - fixed grouping error bug
- changed "group" operator to "groupref"
2000-07-03 21:31:48 +00:00
Fredrik Lundh 6f01398236 - added lookbehind support (?<=pattern), (?<!pattern).
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...

Fredrik Lundh c2301730b8 - experimental: added two new attributes to the match object:
"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.

Fredrik Lundh 7cafe4d7e4 - actually enabled charset anchors in the engine (still not
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.

Fredrik Lundh 3562f11764 -- use charset bitmaps where appropriate. this gives a 5-10%
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.
2000-07-02 12:00:07 +00:00
Fredrik Lundh c13222cdff - fixed "{ in any other context" bug
- minor comment touchups in the C module
2000-07-01 23:49:14 +00:00
Fredrik Lundh 22d2546520 today's SRE update:
-- 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.
2000-07-01 17:50:59 +00:00
Fredrik Lundh 55a4f4a528 - fixed code generation error in multiline mode
- fixed parser flag propagation (of all stupid bugs...)
2000-06-30 22:37:31 +00:00
Fredrik Lundh 4ccea94152 - reverted to "\x is binary byte"
- removed evil tabs from sre_parse and sre_compile
2000-06-30 18:39:20 +00:00
Fredrik Lundh 0640e1161f the mad patcher strikes again:
-- 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)
2000-06-30 13:55:15 +00:00
Fredrik Lundh 43b3b49b5a - fixed lookahead assertions (#10, #11, #12)
- untabified sre_constants.py
2000-06-30 10:41:31 +00:00
Fredrik Lundh b71624e698 - added support for (?P=name)
(closes #3 and #7 from the status report)
2000-06-30 09:13:06 +00:00
Fredrik Lundh 90a0791322 - pedantic: make sure "python -t" doesn't complain... 2000-06-30 07:50:59 +00:00
Fredrik Lundh 01016fe972 - fixed split behaviour on empty matches
- fixed compiler problems when using locale/unicode flags

- fixed group/octal code parsing in sub/subn templates
2000-06-30 00:27:46 +00:00
Fredrik Lundh 8094611eb8 - fixed another split problem
(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.
2000-06-29 18:03:25 +00:00
Fredrik Lundh 4781b07201 - make sure group names are valid identifiers
(closes the "SRE: symbolic reference" bug)
2000-06-29 12:38:45 +00:00
Fredrik Lundh 75f2d675ed - last patch broke parse_template; fixed by changing some
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...)

</F>
2000-06-29 11:34:28 +00:00
Fredrik Lundh 6c68dc7b1a - removed "alpha only" licensing restriction
- removed some hacks that worked around 1.6 alpha bugs
- removed bogus test code from sre_parse

Fredrik Lundh 436c3d58a2 towards 1.6b1 2000-06-29 08:58:44 +00:00
Andrew M. Kuchling 815d5b934b Patch from /F: this patch brings the CVS version of SRE in sync with the
latest public snapshot.""
2000-06-09 14:08:07 +00:00
Guido van Rossum b81e70ebdb Fredrik Lundh: new snapshot. Mostly reindented.
This one should work with unicode expressions, and compile
a bit more silently.
2000-04-10 17:10:48 +00:00
Andrew M. Kuchling e3ba931aa4 This patch looks large, but it just deletes the ^M characters and
untabifies the files.  No actual code changes were made.
2000-04-02 05:22:30 +00:00
Guido van Rossum 7627c0de69 Added Fredrik Lundh's sre module and its supporting cast.
NOTE: THIS IS VERY ROUGH ALPHA CODE!
