Subject: Why call font-lock-add-keywords in a mode hook?
Date: Mon, 25 Jan 2016 11:03:19 +0100 [thread overview]
Message-ID: <878u3ec6xk.fsf@mbork.pl> (raw)
Hi list,
this I found in the manual:
--8<---------------cut here---------------start------------->8---
-- Function: font-lock-add-keywords mode keywords &optional how
This function adds highlighting KEYWORDS, for the current buffer or
for major mode MODE. The argument KEYWORDS should be a list with
the same format as the variable ‘font-lock-keywords’.
If MODE is a symbol which is a major mode command name, such as
‘c-mode’, the effect is that enabling Font Lock mode in MODE will
add KEYWORDS to ‘font-lock-keywords’. Calling with a non-‘nil’
value of MODE is correct only in your ‘~/.emacs’ file.
If MODE is ‘nil’, this function adds KEYWORDS to
‘font-lock-keywords’ in the current buffer. This way of calling
‘font-lock-add-keywords’ is usually used in mode hook functions.
--8<---------------cut here---------------end--------------->8---
My question: why would I want to call this function in a hook if I can
specify the mode in its invocation? (Assuming that I use it in my
init.el, of course.)
TIA,
--
