Fred Drake 788617f8f0 Remove \versionchanged; the text was too complex for the GNU info

note that this applies starting in Python 2.3.

Fred Drake 5b11bdd0ed SF patch #581414: info reader bug 
The "Matching vs. Searching" Info node is unreachable from the Info
program (but is fine in Emacs's Info mode). This patch seems to fix
it.  This is the only occurrence where the info reader fails, so
probably it could be addressed in the python docs as a workaround.
Forwarded the report to the info maintainer.
 2002-07-30 17:51:20 +00:00

Explain that many of the escapes supported by string literals are also
supported by the RE compiler, and list which ones.
This closes SF bug #529923.
 2002-03-25 20:22:59 +00:00

Fred Drake 9479c958c5 Remove extra indenatation from sample interpreter session. 
Remove whitespace from the middle of an inline RE example; it was OK for
the typeset formats, but LaTeX2HTML is more touchy about this.
 2002-03-05 04:02:39 +00:00
Skip Montanaro a8e1d81bdc add simple example of avoiding backtracking 2002-03-04 23:08:28 +00:00

Andrew M. Kuchling 1f774b062e Update obsolete e-mail address, and remove myself as a module author 2001-11-05 21:34:36 +00:00
Tim Peters 7533587d43 Improved error msg when a symbolic group name is redefined. Added docs 
and NEWS.  Bugfix candidate?  That's a dilemma for Anthony <wink>:  /F
did fix a longstanding bug here, but the fix can cause code to raise an
exception that previously worked by accident.
 2001-11-03 19:35:43 +00:00
Fred Drake 0aa811c527 Use the \note and \warning macros where appropriate. 2001-10-20 04:24:09 +00:00
Tim Peters 9835206268 A regexp example was rendered as 
foo\d
when it was clearly intended to render as
    foo$
Fred, is this a right way to fix it?  If not, the earlier place in the
same paragraph that does render as
    foo$
is also wrong.
 2001-10-05 20:06:47 +00:00
Eric S. Raymond 46ccd1dae5 Plant a mention in the description of backreferences of the fact that 
while \0 doesn't do what one might expect, \g<0> does.
 2001-08-28 12:50:03 +00:00
Fred Drake 51629c245a Add a caveat about boundary conditions and RE concatenation, so that the 
documents do not make an overly-strong assertion about the properties of
RE concatenation.

Add an example of RE{m,} syntax and what it will and will not match.
 2001-08-02 20:52:00 +00:00
Fred Drake e74f8de385 Added an example of a string value for the replacement parameter to 
re.sub().
This closes SF bug #446136.

Fixed description of RE modifiers so that RE{#} and RE{#,} are more
clearly described and disambiguated (plain RE{#} had not been described
at all).  Reported by Jeremy Craven via email.
 2001-08-01 16:56:51 +00:00
Fred Drake c547b46c06 Be more specific about corner cases in the description of the $ RE syntax,

This closes SF bug #441600.
 2001-07-23 21:14:59 +00:00
Fred Drake f4bdb57e15 Fix return value for m.group() for groups not in the part of the RE that 
matched; reported by Paul Moore.

Wrapped several long lines.
 2001-07-12 14:13:43 +00:00
Fred Drake 907e76b620 Fix up a few style nits -- avoid "e.g." and "i.e." -- these make 
translation more difficult, as well as reading the English more
difficult for non-native speakers.
 2001-07-06 20:30:11 +00:00
Fred Drake 895aa9da4c Suggestion from Keith Briggs: refer to RE objects consistently instead of 
introducing a new term ("regex") without defining it.
 2001-04-18 17:26:20 +00:00
Fred Drake e20bd19f86 Convert several \seetext references to \seerfc and \seetitle versions. 
These format somewhat better and include more semantic information in the
source.
 2001-04-12 16:47:17 +00:00
Andrew M. Kuchling 75afc0b914 Document the .lastindex and .lastgroup attributes of MatchObject 2000-10-18 23:08:13 +00:00
