Thanks Ian. Yet another reason I need invest in another round of
attempting migration to GNUS ;)
This gives me an idea:
It would be pretty fun to hack something up that allows code snipets
in chat to be font-locked.
I think I'd do it by
1. detecting source and extracting it
2. finding the source type (if possible)
3. creating temp buffer and sett its major mode
4. flow the snippet (grabbed code) into the temp buffer
5. taking buffer-string from temp as replacement (or overlay?) back
into the ERC buffer
This could have a user option that allows configuring the ways it
detect snippets, like an alist of cons cells giving start and end
delimiters? This could look something like
'(("#+\\([^ \t]+\\)?" . "+#")
If a list entry doesn't have an end delimiter I'm SWAGGING that we
would use the start delim as both. The capture group here could be
optional and when it is both given in the start marker and actually
supplied for the snippet found, it is used to pick up the type, thus
set the mode used to fontify in the temp-buffer.
Perhaps a second defcustom to set the "fallabck" type to assume for
delimiter setts that don't give a way to pickup the src type.
If it this did use overlays for additional fun we could buttonized the
result. For example using mouse-1 to pop the snippet that was clicked
(back) into a temp buffer or M-<mouse-1> to get back what was
