Put hide-ifdef on menu-bar?

Put hide-ifdef on menu-bar?

[Nick Roberts]

Howa about adding the hide-ifdef commands to the menu bar for mortals,
like myself who can't remember the key bindings?

Good idea. IMHO all major modes should have a menu, and all the minor
modes that have a significant number of key bindings should have one
too.  It makes it easier for users to discover the functionality.

Now in the case of hide-ifdef, it would be good if there was a menu
entry in the cc-mode menu to turn on this mode. That would make this
feature more discoverable for potential users.

I agree.  On emacs-pretest-bug (Tue, 27 Feb 2007) I previously said:


|  Subject: Move hide-ifdef-mode toggle button

|  I'm not likely to want to toggle hide-ifdef-mode when browsing info, so
|  how about moving it off the list in the pop up menu on the mode line?
                                          [minor mode list]
|  Although it's not part of cc-mode it could be moved to the Toggle...
|  menu-item on the C menu.

but got no reply.  Is hide-ifdef useful for other languages?

Hmm, maybe post this again and if there are not objections check it in.

  > Is hide-ifdef useful for other languages?

It should be useful to all languages that use the C preprocessor: asm
and I think also Fortran.

Seconded.

BTW, in

http://lists.gnu.org/archive/html/emacs-devel/2007-05/msg01503.html

I proposed a patch to optionally shadow such text rather than hide it
which would "make this feature less intimidating for potential users".

Seems like a good idea. What keeps this from being checked in?

As a further enhancement it might be a good idea to put in mouse face on
the #if lines, then the users can click on the item and say
"hide/show". This would make it the feature more obvious.

Eclipse puts folding controls into the fringe... seems like a nice
idea.  The control is a little arrow that points in different
directions depending on whether the code is folded.

IMHO we should have such arrows in the fringe for all modes that do some
hiding. It would be a good visual indication for the user that something
is hidden and would provide an easy way to un-hide.

It's probably not applicable to hideshow since hs-minor-mode doesn't
hide things on a line-by-line basis.

But it'd probably be a good extension for outline-minor-mode, indeed.

Eclipse places many different markers in the fringe: compilation error,
bookmarks, TODO markers, etc.  We could do the same in Emacs but that reminds
me that it's currently not possible to add a tooltip to such markers.  Perhaps
this should be put in TODO.

Also, Eclipse allows fringe elements which do not scroll with the
window contents.  This turns out to be pretty handy.

For instance you could show the user the visible area of the current
buffer (relative to the size of the whole buffer) as a different
background color.  In Eclipse you can see little blocks in the
right-hand fringe which represent errors, problems, etc, and you can
click them to jump to the corresponding point.

I don't think there is a way to do this in Emacs yet, either.

Those things should be put in the scrollbar, don't you think?

Not me, but then I disable the scrollbars but not the fringe.

I do not understand what that means.

That sounds like a scroll bar.  We have scroll bars.
Or perhaps I simply don't understand.

    In Eclipse you can see little blocks in the
    right-hand fringe which represent errors, problems, etc, and you can
    click them to jump to the corresponding point.

I do not understand why you want these not to scroll with the text
they apply to.

But the scroll bar area can't have error markers.

Because then they would be off-screen most of the time.  The idea is to
have all errors in the current buffer visibly indicated and quickly
reachable.  By distributing them in a scroll-bar like area corresponding
to the whole buffer, that becomes possible.

    But the scroll bar area can't have error markers.

Maybe we should put them there.  If the idea is that we want a
vertical strip of screen that corresponds to the whole length of the
buffer, that seems like the way to do it.

Please do.  Also, would someone like to work on implementing that
tooltip feature?
