Executing {{{kbd(M-x replace-regexp)}}} prompts fo a regular expression =REGEXP=
|
||||||
|
and a substitution =NEWSTRING= to replace =REGEXP= with =NEWSTRING=. The tools
|
||||||
|
in section [[#sec:narrowing][Narrowing]] allow to limit the scope of {{{kbd(M-x replace-regexp)}}}.
|
||||||
|
A list pointing to relevant documentation is:
|
||||||
|
1. [[info:emacs#Regexp Replace][Regexp Replace (info)]] explains how the substitution handles references to
|
||||||
|
regular expression groups and lisp expressions.
|
||||||
|
2. [[info:emacs#Regexps][Syntax of Regular Expressions (info)]] describes regular expression features
|
||||||
|
for users.
|
||||||
|
3. [[info:elisp#Regular Expressions][Emacs Lisp Regular Expressions (info)]] describes regular expression features
|
||||||
|
for programmers.
|
||||||
|
4. [[https://www.emacswiki.org/][Emacs Wiki]] has an article on [[https://www.emacswiki.org/emacs/ReplaceRegexpWithLispExpressions][replacing regexp with lisp expressions]].
|
||||||
|
Table [[tab:replace-regexp-tranform]] tabulates how to perfom example tasks by means
|
||||||
|
of {{{kbd(M-x replace-regexp)}}} using =(regular-expression transform)= pairs.
