Raw Blame History

2010-07-20 Miguel de Icaza <miguel@novell.com>
* parser.cs (ParseEscape): Now parses with some context, whether
we are parsing inside a character range which can not contain
back-references or when we are parsing on a string context which
can contain back references.
This fixes bug #577346 which exposed a bug parsing this:
new Regex("[\\177-\\377]")
2010-06-29 Raja R Harinath <harinath@hurrynot.org>

* parser.cs (Parser.ConsumeWhitespace): Add bounds check.
Fix #74753.

intermediate arrays to build the final result.
(Interpreter.GetGroupInfo, Interpreter.PopulateGroup): New helper
functions.
* CaptureCollection.cs (list): Change from ArrayList to list.
(SetValue): New internal helper, used by Interpreter.PopulateGroup.

EvaluateAppend.

2005-05-20 Raja R Harinath <rharinath@novell.com>
Fix #74735.

portion to the "literal" being built.
(ReplacementEvaluator.CompileTerm): Don't throw any exceptions.
If a term cannot be recognized, just return null.

'\' character, don't allocate a new string.

bug #69193.

2005-01-08 Miguel de Icaza <miguel@ximian.com>
* syntax.cs: Applied patch from mei@work.email.ne.jp to fix bug
#71077.
* parser.cs: Turns out that \digit sequences are octal sequences
(no leading zero is needed); And the three octal digit rule
applies to the leading zero as well.
This fixes the Unescape method.
2004-11-29 Gonzalo Paniagua Javier <gonzalo@ximian.com>
* regex.cs: use NextMatch to move on to the next match. Fixes bug
#57274.

2004-10-21 Joerg Rosenkranz <joergr@voelcker.com>
* regex.cs: Fixed a bug introduced with the last patch which
prevented any replacements when a postive count is given.
This also happens in all overloads without count parameter.
2004-10-18 Gonzalo Paniagua Javier <gonzalo@ximian.com>

to the end of the string.
Fixes bug #68398. Patch by Jon Larimer.

* RegexRunnerFactory.cs: removed comment, no longer throw exception
from ctor

internal fields and adding destructor, added MonoTODO attribute to
fields and method that are not yet implemented, changed not
implemented methods to throw NotImplementedException instead of
Exception, fixed names of field that are serialized
2004-06-06 Jambunathan K <kjambunathan@novell.com>
* parser.cs: Fixed issues with Regex.Unescape() identified as part of
debugging bug #58256. The original problem reported was about
inconsistency between the way we treat replacement patterns and the
way microsoft treats the replacement patterns in Regex.Replace(). MS
implementation is buggy and doesn't honour escape sequences in the
replacement patterns, even though the SDK claims otherwise.
2004-06-01 Gonzalo Paniagua Javier <gonzalo@ximian.com>
* syntax.cs: re-applied my patch from 2004-05-27 plus a fix which is
emitting a Category.All if both a category and its negated value are
present.
2004-06-01 Gonzalo Paniagua Javier <gonzalo@ximian.com>
* syntax.cs: reverting my previous patch. It causes bigger problems.
2004-05-27 Gonzalo Paniagua Javier <gonzalo@ximian.com>
* category.cs: added LastValue field to mark the end of enum Category.

of the array needed. Use a BitArray instead of bool[].
In AddCategory(), don't set the opposite category as false. Fixes
bug #59150. All tests pass.
2004-05-25 Jackson Harper <jackson@ximian.com>
* parser.cs: Allow creating a regular expression using {,n} as the
specified. The min bounds is set to -1, I am not completely sure
if that is what it is supposed to be but MS does not set it to 0
based on testing. Patch by dave-gnome-bugs@earth.li. Fixes bug #56761.
2004-05-12 Dick Porter <dick@ximian.com>
* regex.cs:
* quicksearch.cs:
* RegexRunnerFactory.cs:
* RegexRunner.cs: More public API difference fixes.
* GroupCollection.cs:
* MatchCollection.cs:
* CaptureCollection.cs: Moved GroupCollection, MatchCollection and
CaptureCollection so that they no longer inherit from the
non-standard RegexCollectionBase class. Fixes the API difference.

2002-08-28 Juli Mallett <jmallett@FreeBSD.org>
* arch.cs, compiler.cs: Give the interpreter machine a property
for the retrieval of the group count.
* regex.cs: Use the new GroupCount property of the factory to
initialise the current group count, and restructure code to compile
the pattern only the first time it is needed (essentially backing
out the previous revision of regex.cs, to use the new code.)
