Regex Searching in Emacs
- by Inaimathi
I'm trying to write some Elisp code to format a bunch of legacy files.
The idea is that if a file contains a section like "<meta name=\"keywords\" content=\"\\(.*?\\)\" />", then I want to insert a section that contains existing keywords. If that section is not found, I want to insert my own default keywords into the same section.
I've got the following function:
(defun get-keywords ()
(re-search-forward "<meta name=\"keywords\" content=\"\\(.*?\\)\" />")
(goto-char 0) ;The section I'm inserting will be at the beginning of the file
(or (march-string 1)
"Rubber duckies and cute ponies")) ;;or whatever the default keywords are
When the function fails to find its target, it returns Search failed: "[regex here]" and prevents the rest of evaluation. Is there a way to have it return the default string, and ignore the error?
