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

Fred Drake 7bc6f7ac7b Consistently use \textasciicircum to produce a ^ character.

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, 
and include an example where the MULTILINE flag makes a real difference.

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.

source.

 2000-10-10 22:00:03 +00:00
Fred Drake 062ea2e70b Made a number of revisions suggested by Fredrik Lundh.
