Hi,
During search/replace, how can I use the evaluation of a lisp expression as
the substitution string?
An example could be ... say I want to replace the occurrence of a certain
word with the word prefixed with its occurrence count -
For example - If I'd like to replace the occurrence of sea in -
She sells sea shells on the sea shore
with
She sells (1)sea shells on the (2)sea shore.
Or perhaps a more frequent use case of adding line number to each line
(while I was typing this, I got the idea of using the keyboard macro to
achieve this .... is there a better way though?)
Regards,
Kashyap
M-x query-replace-regexp,
\(sea\)
RET
\,(progn (or count (setq count 1))(setq count (1+ count))(concat "("
(number-to-string count) ")" \1))
RET
;;;;;;;;;;;;
\,EXPR
evaluates the expression and the takes the result for replacement.
