How would a regexp look like.? "[:alpha:]+ple[:alpha:]+" I think you should spend some time reading the Elisp manual section on regexps. https://www.gnu.org/software/emacs/manual/html_node/elisp/Regular-Expressions.html And maybe read up elsewhere about regexps: https://www.oreilly.com/library/view/mastering-regular-expressions/0596528124/ Then you can help others with their questions about regexps...

Although I have done (insert (replace-regexp-in-string "\\([:alpha:]+\\)ple\\([:alpha:]+\\)" "\\1p\\2" word)) word is being left intact. ^ permalink raw reply [flat|nested] 6+ messages in thread

It's all in the manual, which you consistently ignore. Please do have a look at it. The [: ... :] character classes only go into the character class brackets (i.e. [ ... ]). So you need two pairs of brackets, like so: [[:alpha:]]. Yes, it looks strange. But it starts making sense when you want to combine things (e.g. alpha plus comma or dash: [[:alpha:],-]) Please, look into the manual. It takes some effort, but it's worth it.
