Hi,
in dired, symlinks look like
symlink -> target
where the whole thing is fontified with dired-symlink-face. But I
already know from the -> that I have a symlink, it would be more useful
to know whether TARGET is a directory, which is what I normally see for
non symlink files in dired by fontification with dired-directory-face.
My proposal: fontify only the first part "symlink ->" with
dired-symlink-face. Fontify "target" according to its truename type.
I'm no expert for font lock, so I don't send a patch but just post the
code I use in my config:
--8<---------------cut here---------------start------------->8---
(cl-callf2 cl-remove dired-re-sym dired-font-lock-keywords :key #'car)
(cl-callf nconc dired-font-lock-keywords
`((,dired-re-sym
((lambda (end) (when (let ((file (dired-file-name-at-point)))
(file-directory-p (file-truename file)))
(search-forward-regexp "\\(.+-> ?\\)\\(.+\\)" end t)))
(dired-move-to-filename)
nil
(1 dired-symlink-face)
(2 dired-directory-face)))
(,dired-re-sym
((lambda (end) (when (let ((file (dired-file-name-at-point)))
(file-regular-p (file-truename file)))
(search-forward-regexp "\\(.+-> ?\\)\\(.+\\)" end t)))
(dired-move-to-filename)
nil
(1 dired-symlink-face)
(2 'default)))))
--8<---------------cut here---------------end--------------->8---
Or could this have any bad side effects? Is it maybe too heavy to call
`file-truename'?
Thanks,
Michael.
