Emacs replace-regexp

Emacs replace-regexp

[Thomas Ruschival]

Hi, 
I guess I am too stupid to read the regexp syntax of Emacs I can't figure out
how to access parts of the match for replace like in perl or awk with
$1,$2....
I'd like to put brackets around the hyperlinks of a latex-document.
do I did a replace-regexp "(\ref\{.*\})" "\[$1\]"
and it doesn't do the trick. so I played a little while with the syntax and
all I got out were "$1" on each place where once was a hyperlink....hmmm.

Please help me out
Thomas Ruschival

You could try reading the documentation in the Emacs manual.

In emacs-regex it's \1,\2,...

your latex-brackets problem: \(\ref{.*}\) -> [\1]

for more help on replace-regexp: C-h f replace-regexp

No.  If at all, \(\\ref{[^}]*}\) -> [\1]

But this is already too complicated. \\ref{[^}]*} -> [\&]

will do the trick.

Better

(info "(emacs)Regexp Replace")
                              ^ press C-x C-e here.

If you have anything helpful to offer to the original question, your
answer would have benefitted from telling your mail agent not to send
HTML-formatted mail.

As it is, you complain about useful advice not given to you in a
useless and annoying way.  Please change your Mailreader to a
generally useful format.  This will let people react more favorably to
your postings even when you are doing nothing more than bitching.
