Hi all,

I wasn't able to google a clear examples of how to do this.  For
example, I'd like to highlight all text between double-quotes.

Typically it looks something like this:

  (font-lock-add-keywords org-mode
                          (list (list (concat "\\(\"[^\"]+\"\\)")
                                      1 highlight-face t)))

Where `highlight-face' is the face you'd like to use.  The regexp doesn't
handle cases where \" legitimately occurs in a string, either.  The part
between the \\(\\) is what gets colorized.

Sorry, that should be 'org-mode, to name the symbol, not attempt to use its
value.

Thanks for the hint, I tried this, but all my beautiful salad bowl
colours went away.

(font-lock-add-keywords 'org-mode '(("\"\\(\\(?:.\\|\n\\)*?[^\\]\\)\""
0 font-lock-string-face)))

Notice that I made a bad attempt to handle escaped quotation mark in
the string.  Does anyone know a better solution to handle escaped
characters in font-lock?

Hi, I want to add custom keywords to be highlighted. I used

    (font-lock-add-keywords nil '(("books" . org-level-4)) t)


but nothing happens after I restart orgmode or call 'font-lock-update'.

The following works for me, in an org mode buffer:

,----
| (font-lock-add-keywords nil '(("books" . 'org-level-4)) t)
`----

(I added a quote before the face name).

No need to call font-lock-update or restart: any new or modified text
gets the new fontification.

Thanks, it works with the quote.
