When typing `C-l' highlighting appears. Is there a possibility to
enforce such redisplay in an efficient way? I could probably call
`sit-for' somewhere in the code but I am not sure if this would be the
right way.
Anyway, below you can find the testcase I promised. Just execute it
and type ''. Then you should see that only the line where '' was
typed is highlighted.
If you uncomment the line setting j-l-c-u-p you should see that the
region gets highlighted after a short delay without having to type
`C-l'.
Here is the code:
(progn
(defun my-match-quote (limit)
(let (start)
(when (setq start (search-forward "``" limit t))
(if (search-forward "''" nil t) ; Do not limit forward search
; for this testcase.
(progn (set-match-data (list start end)) t)
(set-match-data (list 0 0))))))
(defun my-f-l-fontify-region (beg end &optional loudly)
;; For testing purposes we assume that the region should be extended
;; to the start of the buffer.
;; (setq jit-lock-context-unfontify-pos 1)
(font-lock-default-fontify-region 1 end loudly))
(switch-to-buffer (get-buffer-create "*foo*"))
(setq my-f-l-keywords '((my-match-quote . font-lock-string-face)))
(setq font-lock-defaults '(my-f-l-keywords))
(setq font-lock-fontify-region-function 'my-f-l-fontify-region)
(insert "``")
(dotimes (i 1000) (insert "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx\n"))
(font-lock-mode 1)
(backward-char))
