Re-Builder is a great tool. It allows interactive search with
incredibly handy highlight, subexpression mode, etc. However, one
often needs not just search by regexp, but also perform regexp
replace. I thought reb-copy command would help me to pass my regexp to
replace-regexp. But replace-regexp doesn't understand the result of
reb-copy, i.e. for default *scratch* buffer the following regexp works
in Re-Builder:
"\\(file\\)"
but to make it suitable for search-forward-regexp/replace-regexp I
need to manually adjust it to
\(file\)
I find it really inconvenient (the larger regexp the more
inconvenient). Should I report a bug, or I'm missing something basic?
I'm running GNU Emacs 23.3.1.

Hi Andrey,
think these are valid considerations on the road.
A lot of questions are around.
For example using Regexps are one way. Exist other procedures.
Also writing a function to perform replacements is faster in some cases
then doing it with just one regexp.
In all cases being tempted to use such a tool, rather split the issue.
Writing a function which changes
> "\\(file\\)"
>
> \(file\)
should be a way to proceed.
HTH,
Andreas
