New Revision: 39135
URL: http://www.lyx.org/trac/changeset/39135
Log:
Now Adv. F&R correctly interprets escape sequences within regexp insets, e.g.,
\\ or \(, for finding characters with a special meaning in regular expression
context (\^()[]).
Added corresponding regression tests findadv-re-01 and -02 for finding these
special characters.
Unfortunately, braces {} are a little bit special and don't work yet. Added
findadv-re-03 regression test to not forget about this case.
This goes along the line of fixing issues reported by Andrew Parsloe and
summarised as #7638.
Last note: Still there will be cases when the Advanced F&R won't work,
especially if the text to be found and/or the search pattern is preceded by
backslashes or others.
