highlight parts of various buffers

highlight parts of various buffers

[Martin Rubey]

Hi,

I would need a (minor) mode that allows me to select arbitrary parts of the
buffer with the mouse to 'highlight' them, just as if I could take my pen and
underline some parts of the text (or numbers, in fact).

It would be wonderful to have this,

Martin

Select the text with the mouse, then type `M-g u'.

(sorry Kevin, I pressed the wrong button, so it ended up as mail instead of as
follow-up)

Thanks a lot, but this seems to work only in fundamental mode? I need in in
Inferior Lisp mode though.

(apart from this, it seems to be quite what I need, thank you very much)

It works for me.  What version of Emacs are you using?  Can you select text with

the mouse in Inferior Lisp mode?  What does `C-h k M-g u' say?

I have M-g bound to goto-line... mistake I guess.. what is it bound
to for you?  Or is there a way to see what the default keymapping is
without restarting emacs with -q.  I didn't know there was a way to
highlight like that outside of the highlight-regex funcs.

Thanks.

M-g is bound by default to `facemenu-keymap', but perhaps some local

customization file overrides that.  (Only the `C-c LETTER' key sequences

are reserved for users and well-behaved libraries.)  Does it work if
you invoke Emacs without any local customizatons (emacs -q --no-site-file)?

The site-lisp file shipped with Mandrake and Red Hat does this
unfortunately.  Its a pity really, since goto-line isn't very useful.

You could:-
- turn of font-lock-mode
- turn on highlight-changes-mode
- turn font-lock-mode back on again

In my Emacs this works, but it looks like someone needs to make
highlight-changes-mode work with font-lock.

I missed the beginning of this thread.
Could you post a bug-report describing the problem and how to reproduce it?

I can't replicate the program, it must have been something to do with my setup.

Sorry, false alarm.

Do you use font-lock-mode?  M-g u didn't work for me in emacs-lisp-mode with
font-lock on.  It worked when I switched font-lock off.

Yes, it seems that this is the problem. Thanks a lot.

Yes

> What does `C-h k M-g u' say?

When I press `C-h k M-g u' being in my Inferior Lisp buffer, I get

M-g u runs the command facemenu-set-underline
   which is an interactive Lisp function.
(facemenu-set-underline)

Select face `underline' for subsequent insertion.

In fact, pressing M-g in the Inferior Lisp buffer asks me which face I want, so
I press `b' for bold, for example, but then nothing happens - not a beep, no
message in *Messages*, simply nothing.

If I switch to fundamental mode or text mode, set the face of the text (this
works), and switch back to Inferior Lisp mode afterwards, the boldface (or
whatever) disappears immediately.

Very strange
