How to font lock buffer name starts with space

How to font lock buffer name starts with space

[Ye Wenbin]

Hi, I want some buffers hide from list-buffers, so I add an space to the  
buffer's name.
But it turns that the font lock is inhibit for the buffer name starts with  
space.
How to active font-lock for that buffer?

That's tricky because skipping hidden buffers is hard-coded in the
`font-lock-mode' function.  Interactively, I guess you could rename
the buffer at an opportune moment using M-x rename-buffer or a piece
of advice like so (largely untested):

(defadvice font-lock-mode (around fontify-hidden-buffers compile activate)
  "Allow hidden buffers."
  (let ((original-buffer-name (buffer-name))
        new-buffer-name)
    (unwind-protect
        (progn
          (setq new-buffer-name
                (generate-new-buffer-name original-buffer-name))
          (rename-buffer new-buffer-name)
          ad-do-it)
      (rename-buffer original-buffer-name))))

I know its not the answer for your question, but maybe it would be
interesting for you to start using Ido for switching buffers?

Then you can choose which ones to hide from the list like this:

(setq ido-ignore-buffers '("^ " "^\\*" "^\\#"  "muse$")) ;; ignore
*Messages* etc
