Hi. I'm running a very recent build of emacs from git:
https://github.com/emacs-mirror/emacs/commit/0aec2aaccd8b745fa7214f3edd453c04a04bfba4
I just found another isearch regression. Recipe:
1. emacs -Q
2. Create or open file such that the buffer contains

-------------------------
i.e two identical long lines containing lots of words '1234'.
3. Point to start of buffer
4. C-s
5. C-w multiple times. As you press C-w, you grow the string being
sought; you can see the match highlighted on the line being selected and
on the next line
4. Eventually (column 239 or so) the minibuffer says 'too many words',
and the search no longer matches anything on either line. The sought
string looks like it's appending words without spaces ("123412341234"
instead of "1234 1234 1234"). Manually fixing that with M-e doesn't
appear to help.

A possible solution in case of the error “Too many words” is to fall back to the ordinary search, and continue the search with success: diff --git a/lisp/isearch.el b/lisp/isearch.el index 8d4bf24..a888f79 100644 --- a/lisp/isearch.el +++ b/lisp/isearch.el @@ -2720,6 +2734,10 @@ (defun isearch-search () ((and (not isearch-regexp) (string-match "\\`Regular expression too big" isearch-error)) (cond + ((eq isearch-word #'character-fold-to-regexp) + ;; Fallback to an ordinary search + (setq isearch-word nil) + (isearch-search)) (isearch-word (setq isearch-error "Too many words")) ((and isearch-lax-whitespace search-whitespace-regexp) ^ permalink raw reply related [flat|nested] 4+ messages in thread
