Subject: bug#22147: Obsolete search-forward-lax-whitespace
Date: Sat, 12 Dec 2015 01:52:03 +0200 [thread overview]
Message-ID: <87wpsk7dcs.fsf@mail.linkov.net> (raw)
After commit e5ece322 that removed a layer of indirection for lax-whitespace
it's not possible anymore to override search-forward-lax-whitespace
with own implementation to ignore all possible whitespace instead of
just spaces in the search string.
For example, such customization as this one:
(setq search-whitespace-regexp "\\(\\s-\\|\n\\)+")
(defun search-whitespace-regexp (string)
"Return a regexp which ignores all possible whitespace in search string.
Uses the value of the variable `search-whitespace-regexp'."
(if (or (not (stringp search-whitespace-regexp))
(null (if isearch-regexp
isearch-regexp-lax-whitespace
isearch-lax-whitespace)))
string
(replace-regexp-in-string
search-whitespace-regexp
search-whitespace-regexp
string nil t)))
(defun search-forward-lax-whitespace (string &optional bound noerror count)
(re-search-forward (search-whitespace-regexp (regexp-quote string)) bound noerror count))
(defun search-backward-lax-whitespace (string &optional bound noerror count)
(re-search-backward (search-whitespace-regexp (regexp-quote string)) bound noerror count))
(defun re-search-forward-lax-whitespace (regexp &optional bound noerror count)
(re-search-forward (search-whitespace-regexp regexp) bound noerror count))
(defun re-search-backward-lax-whitespace (regexp &optional bound noerror count)
(re-search-backward (search-whitespace-regexp regexp) bound noerror count))
allowed to search for a string with a newline like ‘C-s abc C-q C-j def’
and match the text “abc def”.
It's not clear what to do with this customization now using
a replacement recommended in (make-obsolete old "instead, use (let
((search-spaces-regexp search-whitespace-regexp)) (re-search-... ...))"
