Subject: bug#12679: 24.2.50; Can't font-at for the beginning of a string
Date: Sat, 20 Oct 2012 14:19:54 +0200 [thread overview]
Message-ID: <508296EA.60000@gmx.at> (raw)
In-Reply-To: <87objywqrz.fsf@gnu.org>
Could you please also (1) add a description of the STRING argument in
the doc-string of `font-at', and (2) explain what happens when the
selected window or the window passed as argument do not show the current
buffer. IIUC face_at_buffer_position expects the window passed to it to
show the current buffer but this might not be true when `font-at' calls
it. There's also this comment in face_at_buffer_position:
/* W must display the current buffer. We could write this function
to use the frame and buffer of W, but right now it doesn't. */
/* eassert (XBUFFER (w->buffer) == current_buffer); */
Later in the code of face_at_buffer_position I see that w->buffer is
sometimes used explicitly but get the impression that most other parts
of the code use the current buffer instead.
Thanks, martin
