Fredrik Lundh b35ffc0417 added "magic" number to the _sre module, to avoid weird errors caused
by compiler/engine mismatches
2001-01-15 12:46:09 +00:00
Fredrik Lundh 770617b23e SRE fixes for 2.1 alpha:
-- added some more docstrings
-- fixed typo in scanner class (#125531)
-- the multiline flag (?m) should't affect the \Z operator (#127259)
-- fixed non-greedy backtracking bug (#123769, #127259)
-- added sre.DEBUG flag (currently dumps the parsed pattern structure)
-- fixed a couple of glitches in groupdict (the #126587 memory leak
   had already been fixed by AMK)

Fredrik Lundh 13ac9926ac Fixed too ambitious "nothing to repeat" check. Closes bug #114033. 2000-10-07 17:38:23 +00:00
Fredrik Lundh e186983842 final 0.9.8 updates:
-- added REPEAT_ONE operator
-- added ANY_ALL operator (used to represent "(?s).")
2000-08-01 22:47:49 +00:00
Fredrik Lundh 29c4ba9ada SRE 0.9.8: passes the entire test suite
-- 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

Fredrik Lundh 8a3ebf8ca8 -- SRE 0.9.6 sync. this includes:
+ added "regs" attribute
 + fixed "pos" and "endpos" attributes

 + 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

Thomas Wouters 7e47402264 Spelling fixes supplied by Rob W. W. Hooft. All these are fixes in either
comments, docstrings or error messages. I fixed two minor things in
test_winreg.py ("didn't" -> "Didn't" and "Didnt" -> "Didn't").

There is a minor style issue involved: Guido seems to have preferred English
grammar (behaviour, honour) in a couple places. This patch changes that to
American, which is the more prominent style in the source. I prefer English
myself, so if English is preferred, I'd be happy to supply a patch myself ;)

Fredrik Lundh 72b82ba16d - fixed grouping error bug
- changed "group" operator to "groupref"
2000-07-03 21:31:48 +00:00
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.
2000-07-02 17:33:27 +00:00
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 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 43b3b49b5a - fixed lookahead assertions (#10, #11, #12)
- untabified sre_constants.py
2000-06-30 10:41:31 +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 6c68dc7b1a - removed "alpha only" licensing restriction
- removed some hacks that worked around 1.6 alpha bugs
- removed bogus test code from sre_parse

Jeremy Hylton b1aa19515f Fredrik Lundh: here's the 96.6% version of SRE 2000-06-01 17:39:12 +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.

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!
