Re-Builder is a great tool. It allows interactive search with

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:

I find it really inconvenient (the larger regexp the more
inconvenient). Should I report a bug, or I'm missing something basic?

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.
