In Emacs, how can I avoid line breaks within |...| when using M-q (fill-paragraph)?
In https://groups.google.com/forum/?fromgroups#!searchin/gnu.emacs.help/fill-nobreak-predicate/gnu.emacs.help/qNuZZjQnsww/99oJ1fb4OSUJ I found the following solution for [[...]], but it doesn't work when the open and close delimiters are the same:
(defun fill-open-link-nobreak-p ()
"Don't break a line after an unclosed \"[[link \"."
(save-excursion
(skip-chars-backward " ")
(let ((opoint (point))
spoint inside)
(save-excursion
(beginning-of-line)
(setq spoint (point)))
(when (re-search-backward "\\[\\[" spoint t)
;; (message "found") (sit-for 2)
(unless (re-search-forward "\\]\\]" opoint t)
(setq inside t)))
inside)))
(add-to-list 'fill-nobreak-predicate 'fill-open-link-nobreak-p)
