Tabs in Emacs?

Tabs in Emacs?

[Angelo Graziosi]

I would ask if there are plans to add tabs, as many modern applications 
have, for Emacs 23.2.

Cheers,
Angelo.

There is already e.g. tab bar mode, but it's not part of "core" Emacs today:

Not belonging to CVS, yet. Right?

The last time I looked at the possibility to implement "real" tabs
in GTK, there was a problem of attaching GtkNotebook to a widget.
It's possible to bind a Gtk tab to a fake widget or to the same
basic frame.  This produces a warning, but should basically work
by binding GCallback from a tab to any function that we can use
to implement Emacs-specific tab handling.

Dear Emacs developers, please do *not* spend your valuable time on features like
this. Tabs feature is already very well implemented in worthy window managers
(for example Fluxbox), and it works. Instead, please focus on things which are
broken, for example printing (http://thread.gmane.org/gmane.emacs.devel/109887).

Sorry for not being constructive.

Why would someone need tabs in GNU Emacs exactly ? I am
curious. Buffers and related functions (browsing, navigating,
filtering ... ) are so powerful that I do not clearly understand
the need for such features.

If implemented well, tabs can be a nice visual reminder of recently used
buffers and UI for simple and quick mouse use.

They clearly aren't a _replacement_ for the more powerful underlying
functions, but I think they can be a useful addition (and make people
used to tabs in other programs feel warm&cozy).

Actually, to manage window-configs, I think it might make sense.
I use frames for that (and if your WM supports tabs, you may end up
with the same functionality), but not everyone likes it that way.

This doesn't mean it's a high-priority feature, but if someone writes it
cleanly, I'll happily accept it.  IIUC Alin Soare <as1789@gmail.com> has
already started work on it.

I think that speaking of functional differences and usage patterns is
more useful in this discussion.

Anyway, previously I used Vim editor and found its tab feature handy and
very intuitive way for maintaining and switching between different
window configurations. With Emacs I use frames but I'd prefer having a
nice tab-like functionality within a single X Window frame. I don't care
if it is called "tabs", but just an intuitive way to switch between
different window configurations would be very useful.

Hum yes. I am always in the linux console thus I do not need more
stuff. But I am pretty sure that even in X, I would not run the
graphic toolkit ;).

Sorry for the digression.

> Thoughts?

What you describe was implemented in the first prototype of
http://thread.gmane.org/gmane.emacs.devel/93208/focus=94508
that I have later used as the basis of implementing "real" tabs.

In the current implementation, the frame-based tab-bar is located
below the tool-bar.  The C part mostly duplicates code from the
non-tookit implementation of the tool-bar.  So there already exists
a non-tookit version of the tab-bar that works without crashes.

As for the GTK implementation, I still have unresolved problems.
I'd like to share the current code, so all Emacs developers would
be able to contribute to the development of the GTK part or to
improve code to place the tool-bar and the tab-bar anywhere
in the window tree, etc.

Sending a 4000-line patch to emacs-devel@gnu.org doesn't make sense.
Ideally, I'd like to create a new branch in a dVCS.  I regret we still
not switched to bzr where a new branch could be created cheaply.

Any suggestions on how to proceed with the implementation instead
of many years of talking about benefits of this highly useful feature?
(I can't now image how I used Emacs without tabs in a one-frame
configuration.)

I happily use Emacs tabs in the console since internally tabs are just
a list of window configurations that can be displayed in any way.

I did solve the problem. I did write the C code for the tabs of Emacs 1 year ago, but, unfortunately, I had to postpone to send it to emacs.

The code is almost finished, and I believe that in Avril/May I will have time to finish and send it.

I have to add code for Athena/Motif, and that is all.

I attach here a picture of the tabs in GTK and a picture with the tabs in console.

Good news that you have implemented GTK and console part of the tabs
implementation as I have implemented only the non-toolkit part.

Any chance to merge with your code soon?

I will reopen the archives in the first half of the next year. Until then, I do not have time.

Why don't you send you patch here so others can look at it and maybe
work on it if they have the time (and inclination)?

I have changed the definition of a frame, and I was into the point to replace everywhere FOR_EACH_FRAME with the new correct form.

I do not want to send the code before I replace it everywhere where it must be replaced, and this will be some work.
