Adding xterm-extras to Emacs

Adding xterm-extras to Emacs

[Leo]

Dear all,

When I run emacs in terminal like xterm I find that xterm-extras.el¹
crucial. It makes almost all key bindings available in X also available
in terminal.

I wonder if we can include the file or add such functionality to
an appropriate existing package in Emacs.

In emacs-22 xterm-extras.el is not needed anymore, term/xterm.el
should bind all the keys that xterm-extras.el does (and more). 

If you know of any bindings that are still missing, please point them
out and they will be added.

xterm-extras.el also required you to fiddle with X11 resources, this
is not needed now.

I check term/xterm.el and it seems a lot of key combinations should be
available. However I randomly choose two key bindings

'C-;'     => inserts ';'
'M-S-up'  => inserts 'A'

This only works if you set modifyOtherKeys to 1 and iff you have a new
enough xterm (after 216). This didn't work with xterm-extras.el

  > 'M-S-up'  => inserts 'A'

Does it do that if you start from emacs -Q? 
Can you show the result of C-q M-S-up   ?
(My window manager uses M-S-up so I can't test that one).

Thanks for the tip. Is this mentioned somewhere?

It inserts: ^[[1;4A

It is briefly mentioned in NEWS.

Oops, I didn't pay enough attention: there's no support for any M-S-
key bindings. No idea why, there AFAICT nothing in emacs uses them and
nobody requested them ...

These key bindings work if xterm-extras.el is loaded.

Org.el uses them.

I meant that term/xterm.el does not support any M-S- bindings. 

I can add bindings for M-S- keys in a few days if there's no objection
to such bindings. Patches are welcome!

Funny this comes up - have been banging my head on this for a few days  
already (C-S-key, actually).  Good to know I am not the only one...  (just  
for the usecase, makes vcursor with default bindings pretty useless in  
terminal).

Hi Dan,

When we discussed this by e-mail some time ago, I suggested that rather
than limiting term/xterm.el to those bindings currently used by Emacs,
we should provide mappings for all possible escape sequences emitted by
a current xterm with modifyOtherKeys set.

The reasons for this are: (1) it's hard to get a list of all bindings
used by all modes that ship with Emacs, and (2) many users define
additional bindings in their .emacs file which work with X11, and which
they might like also to work with xterm.

That was the approach I tried when I wrote xterm-extras.el.  That
package is now out-of-date, since it predates the appearance of
modifyOtherKeys.  When I wrote xterm-extras, the xterm source came with
a file that documented the escape codes, which made it reasonable to
attempt comprehensive coverage in Emacs.

If you tested it, please put it in, both trunk and 22 branch.

What keys did you have problems with? What terminal emulator + version?
Some C-S-keys are supported, please look in term/xterm.el and check if
the keys you are trying to use appear there.

That is certainly a valid approach. I didn't take because at the time
I did that work emacs was in a feature freeze for the 22.1 release. I
didn't want to have the changes postponed for after the release, so I
tried to do the minimal, but still enough for useful work.

I don't have a strong opinion about this, but before moving in that
direction I would like to hear at least Eli's and Stefan's opinion.

BTW, new packages are being accepted now in Emacs CVS, so this is
probably a good moment to submit your ispell-multi and
flyspell-babel...

I guess it made sense then, but now I encourage people to add such
exhaustive keybinding to term/xterm.el.  Ideally, part of the contents of
term/xterm.el should be auto-generated from the source code (or the doc) of
the xterm program, so we can be sure we're complete and up-to-date.

Hm,  my bad - turns out this is more of a terminal problem than emacs (and  
thus off-topic): xterm 225, with
	XTerm*modifyOtherKeys:  1
C-S-<key>, where <key> is an alphabetic character, are just interpreted as  
^<key> - not much any emacs fix could do about.

I don't think that the docs or the source code are too amenable to
automatic analysis (although I would love to be proven wrong in
practice).

I will start adding M-S- bindings when I have some free time to play
with this. If people can point out what other bindings should be added
that would be very helpful. Any help/patches are more than welcome.

I have installed the newest xterm.el and now it seems M-S- key bindings
work in xterm.

However, C-S- and C-M- still don't.

If you want to be helpful, please show an exact list of what keys are
not working.
But before doing that, please make sure that xterm can generate those
keys, not all key combinations are possible.

The following are what I have found not working:

C-M-up       ;; ^[[1;7A
C-M-down     ;; ^[[1;7B
C-M-left     ;; ^[[1;7D
C-M-right    ;; ^[[1;7C

C-S-up       ;; ^[[1;6A
C-S-down     ;; ^[[1;6B
C-S-left     ;; ^[[1;6D
C-S-right    ;; ^[[1;6C

S-up         ;; ^[[1;2A
S-down       ;; ^[[1;2B
S-left       ;; ^[[1;2D
S-right      ;; ^[[1;2C

I will try to post here if I find more.

I'll add these. What window manager are you using? The ones that will
not allow these to the application...

These have been there for a long time, and they work fine for me.
How did you test them?

I use xmonad, all its key bindings start with [win].

I start emacs with 'emacs -nw -q' and test them with 'C-h k'.

What C-h k says for those keys might be misleading.
Try 
emacs -nw -q
M-x cua-selection-mode RET
and now try to use the S- C-S- keys, they should select/extend the selection for
a region. Did that work?

Except <S-up>, the rest seem working.

However, it S-left and left is the same in 'C-h k', how can I bind them
to different commands?

In what way is S-up misbehaving?

They are different, you can bind them just fine. I don't remember the
explanation why is C-h k showing them like that.

<S-up> didn't move the selection up (it didn't move at all) in
cua-selection-mode.

I will now stop using xterm-extras.el and see if there are key bindings
stop working.

Thank you for fixing this.

C-h k shows the "raw data" as well as the "final event".  It doesn't show
all the intermediate steps.  In this case one of the steps is to turn the
escape sequence into S-left, and another step turns `S-left' into `left'
(because Emacs always tried to unshift a key to find a binding in case
where the shifted version has no binding).

I.e. under X11 where the "raw data" is already a `S-left', C-h k shows:

   <left> (translated from <S-left>) runs the command backward-char

That last step (unshifing) is omitted if you try to bind the key
interactively.

Strange. What do you get when typing:

C-q S-up

^[[1;2A

In cua-selection-mode, S-up displays "<select> is not bound".

That is the correct string, xterm.el binds it.

No idea where this could come from.

What does C-h k S-up say?

What might be happening is that your termcap/terminfo data tells Emacs to
bind this sequence to `select'.

The current xterm.el does not cover the functionality of
xterm-extras.el. So I will continue using it.

If would be favorable, if you can study xterm-extras.el and include
those you see fit.

The output is attached. Does it say that 'select' is bound to "S-up"? Thanks.

The binding is done here:

term.c:1630:      CONDITIONAL_REASSIGN ("*6", "kU", "select");

Given that you are interested in this and you seem to know that
something is missing, why don't you provide a proper bug report with
what is missing???

To produce a full bug report is difficult as I only know how to use an
XTerm and no more than that. With the recent change, <S-up> is not shown
as <select> under `C-h K' any more.

However the following key bindings are recognized differently in `C-h
K':

Alt-right => <A-right>
Alt-left => <A-left>
Alt-up => <A-up>
Alt-down => <A-down>

You just need to show what keys are missing, nothing more.

Then something has changed in your setup, AFAIK nothing has changed in
emacs to change that.

I am not sure I understand what you mean here, please explain in a bit
more detail. It's unclear if the above refers to the emacs defaults or
xterm-extras.el...

I will report them when I see them.

I haven't changed any of my setup. Maybe the following change:

,----

| applies before function-key-map.  Also it is terminal-local contrary to

It is tested in 'emacs -nw -q' (exterm-extras.el is not loaded).

Type `C-h k' and then type "Alt + RightArrow", it shows in the
minibuffer:

"<A-right> is undefined"

I was hoping to see "<M-right> is undefined".

Just tell us which keys are not recognized (i.e. say key A-C-foo is not
recognized and give us the corresponding escape sequence, which you can
recover from C-h l).

Not sure which change could have caused that.  Does it show up as S-up now?
If so, I'm glad to hear it ;-)

Is that good or bad?  The above looks right to me.  What was it before?
What should it be instead?

It might be due to some changes in my .Xresources.

What's the recommended setting for XTerm?

,----
| XTerm.termName: xterm-256color
| XTerm*scrollBar: off
| XTerm*metaSendsEscape: true
| XTerm*backarrowKey: false

I was expecting to see <M-right> etc. For example some modes bind
`M-right' to a command. But I could only invoke it by "Esc + RightArrow"
and not "Alt + RightArrow".

Have you tried with other "alt" keys?  There's always this issue about
Alt-vs-Meta, so normally xterm converts the Meta modifier into an ESC prefix
(via the "metaSendsEscape" which you seem to have set as well).
If you don't like to distinguish Meta from Alt, then maybe you should play
with xmodmap to turn all your Alt keys into Meta keys or vice-versa.

However, Alt+Ctrl+Right is shown as "<C-M-right>" but not "<C-A-right>"
while Alt+Right is shown as "<A-right>" but not <M-right>. You can see
they are _INCONSISTENT_.

(What I mean by 'shown' is by what is displayed when the key binding is
tested in 'C-h k'.)

Can you check C-h l as well to see if Alt+Ctrl+Right sends ESC followed by
the escape sequence for Ctrl+Right and if Alr+Right does the same.
If not, then the inconsistency is in xterm and should be reported there
(after reporting there, we may also decide to workaround the problem in
Emacs by binding those escape sequences to M-right instead).

Yes, it looks like Alt+Ctrl+Right and Alt+Right send ESC.

You mean "it looks like they *don't*"!  The ESC you see are the first char
of an escape sequence, not standalone ESC characters.

What "metaSendsEscape" is supposed to do is to turn Alt+A into ESC A, so if
Right sends ^[[C (aka ESC [ C), then Alt+Right should send ^[^[[C (aka ESC
ESC [ C).  Please report this as a feature request to xterm's maintainers.

But looking at lisp/xterm.el now I see that we indeed inconsistently map
things to S-M-foo but A-foo, so the inconsistency is our fault and should be
corrected with the patch below,

I have updated xterm.el to the latest and now Alt+Right is recognized as
<M-right> etc.

Do you still think that xterm is missing the feature?
