extended regexp

["damien.thiriet77" <damien.thiriet77@laposte.net>]

Hello,


I have been recently doing a lot of regexp with grep, sed and emacs and I think differences between regexp syntax of those programs are a bit confusing (I am using GNU sed, GNU grep and GNU emacs). Extended regexp somehow unify these syntaxes, and I would link to know if there is a way to implement them in emacs regexp search and replace. I would like to do so for another reason: I have quite often to escape ( and { in my regexp, which is quite tedious. Of course, I suppose the default behaviour of ( in regexp is connected with lisp syntax, but I mostly use search-replace in texts with few (). I made a research in both emacs info manual and emacs wiki and couldn’t find anything on it. As far as I remember, vim has got such extended regexp-like functions.

If there is no extended-regexp functions nor mode avalaible, I may send a feature request for it (the idea would be to have a regexp variable for usual or extended search and replace). However, do you think someone else might be interested by such a behaviour?
