Q: tmux sending different key escape codes for Option+Left/Right depending on $TERM?

Hello,

I'm using tmux 1.9a in Terminal.app 343.7 (OS X 10.10). I noticed by
accident that when I press Option+Left/Right I get different escape
codes, depending if the $TERM variable outside tmux is set to 'nsterm'
or 'xterm'.

For example, when pressing Option+Left:

$TERM=='nsterm': ^[^[OD or ^[^[[D (depends on application mode)
$TERM=='xterm': ^[b (does not depend on the mode)

The option 'xterm-keys' is off in both cases.

I'm just wondering if this behavior is documented because I could not
find any references in the man page. I'm interested (for no particular
reason besides my personal curiosity) in finding out what's the exact
logic that tmux uses to determine the escape sequence to send to the
application; I inspected the source code but I'm not familiar with the
codebase and I'm having trouble figuring this out on my own. I would
appreciate if somebody could shed some light on this.

For reference, these are my terminfo capabilities:

Hi

What does the terminal actually send outside tmux for Option+Left?

You should be able to see by running "cat" and then pressing the keys.

^[b. It's an explicit binding that comes pre-configured by default in
Terminal.app (but can be changed). It does not change if the terminal is
in application mode or not (explicit bindings always generate the same
sequence).
Post by Nicholas Marriott

Yes. That's how I captured the tmux escapes in the first place. (I'm
also sending smkx or rmkx before 'cat'.)

Hello,
I'm using tmux 1.9a in Terminal.app 343.7 (OS X 10.10). I noticed by
accident that when I press Option+Left/Right I get different escape
codes, depending if the $TERM variable outside tmux is set to 'nsterm'
or 'xterm'.
$TERM=='nsterm': ^[^[OD or ^[^[[D (depends on application mode)
$TERM=='xterm':  ^[b (does not depend on the mode)
The option 'xterm-keys' is off in both cases.
I'm just wondering if this behavior is documented because I could not
find any references in the man page. I'm interested (for no particular
reason besides my personal curiosity) in finding out what's the exact
logic that tmux uses to determine the escape sequence to send to the
application; I inspected the source code but I'm not familiar with the
codebase and I'm having trouble figuring this out on my own. I would
appreciate if somebody could shed some light on this.

Positive. Just double checked via cat: ^[b. In Terminal.app preferences
it's shown as \033b.

Hmm weird.

There is nothing in the nsterm terminfo to make tmux think that M-b is
actually M-Left.

Please run "TERM=nsterm tmux -Ltest -f/dev/null new" then press Option+Left
a few times, then exit tmux and send me the tmux-server-*.log that will
be in the current directory.

Are you sure it is \[b not \[[b?
Positive. Just double checked via cat: ^[b. In Terminal.app preferences
it's shown as \033b.

Subject: Re: Q: tmux sending different key escape codes for
Option+Left/Right depending on $TERM?
On 06 May 2015, at 17:21, Nicholas Marriott
Hi
What does the terminal actually send outside tmux for Option+Left?
^[b. It's an explicit binding that comes pre-configured by default in
Terminal.app (but can be changed). I am almost certain that it does not
depend on the application mode (explicit bindings don't) but I'll
confirm that once I use my Mac again and I'll reply in case I'm wrong.
You should be able to see by running "cat" and then pressing the keys.
Yes. That's how I captured the tmux escapes in the first place. (I'm
also sending smkx or rmkx before 'cat'.)
On Wed, May 06, 2015 at 04:59:12PM +0200, Leonardo Brondani Schenkel
Hello,
I'm using tmux 1.9a in Terminal.app 343.7 (OS X 10.10). I noticed by
accident that when I press Option+Left/Right I get different escape
codes, depending if the $TERM variable outside tmux is set to 'nsterm'
or 'xterm'.
$TERM=='nsterm': ^[^[OD or ^[^[[D (depends on application mode)
$TERM=='xterm': ^[b (does not depend on the mode)
The option 'xterm-keys' is off in both cases.
I'm just wondering if this behavior is documented because I could not
find any references in the man page. I'm interested (for no particular
reason besides my personal curiosity) in finding out what's the exact
logic that tmux uses to determine the escape sequence to send to the
application; I inspected the source code but I'm not familiar with the
codebase and I'm having trouble figuring this out on my own. I would
appreciate if somebody could shed some light on this.

Please run "TERM=nsterm tmux -Ltest -f/dev/null new" then press Option+Left
That should be:

Hi

"new key ^[b: 0x301f (M-Left)"

Are you sure your tmux is unmodified?

Did you use "infocmp -x" when dumping the terminfo entries you sent? If
not, try "infocmp -x nsterm" and look for kLFT3.

"new key ^[b: 0x301f (M-Left)"
Are you sure your tmux is unmodified?
It's the version available on MacPorts. As far as I can see it does not
patch tmux in any significant way:
https://trac.macports.org/browser/trunk/dports/sysutils/tmux?rev=132936

Actually tmux 2.0 just landed in MacPorts but I didn't install it yet.
I can upgrade to it and repeat the experiment if it might help.

Did you use "infocmp -x" when dumping the terminfo entries you sent? If
not, try "infocmp -x nsterm" and look for kLFT3.
No, sorry, I overlooked that and didn't use "-x". The output with "-x"
is listed below. kLFT3 is not there, but I checked my terminfo sources
(I'm using a custom ~/.terminfo compiled from the latest database:
version 1.536) and KLFT3 *is* present (in fact I was the one who
actually suggested these new capabilities/entries in the ncurses mailing
list in the first place):

Hi
Well that explains it, since you have kLFT3=\Eb tmux will send M-Left
instead of M-b for \Eb (and Option+Left since your terminal sends \Eb
for that too).
All right, so just to make sure that I understand the logic...

When TERM is 'xterm-256color':
1. tmux receives an \Eb from the terminal
2. tmux does not recognize the sequence (not in terminfo)
3. tmux forwards this sequence "as is" to the application

When TERM is 'nsterm':
1. tmux receives an \Eb from the terminal
2. tmux notices that \Eb is kLFT3 (Alt+Left) in terminfo
3. tmux translates Alt+Left into KEYC_LEFT|KEYC_ESCAPE (tty-keys.c)
4. tmux KEYC_LEFT is ^[[D or ^[OD, depending on the mode
5. tmux sends KEYC_LEFT|KEYC_ESCAPE to the application

Makes perfect sense. However, since I get ^[[D or ^[OD in cat, where did
KEYC_ESCAPE go? Shouldn't I be getting ^[^[[D or ^[^[OD instead? What am
I missing here? It looks to me that I'm pressing Alt/Option+Left in the
terminal but the app is receiving just a Left, and the Alt went missing.

2. tmux does not recognize the sequence (not in terminfo)
3. tmux forwards this sequence "as is" to the application
Almost. tmux recognises this as M-b:

keys are 2 (^[b)
complete key ^[b 0x2062
writing key 0x2062

0x2062 is 0x2000 (Meta) + 0x62 (b).

It isn't sent as-is (there is still a translate step), it just has that
effect.

This doesn't seem to be the case, from your logs:

keys are 2 (^[b)
complete key ^[b 0x301f
writing key 0x301f
found key 0x301f: "^[[D"

This shows tmux found ^[[D for 0x1f (the key is looked for without the
modifiers).

Then:

input_parse: '^' ground
input_parse: '[' ground
input_parse: '^' ground
input_parse: '[' ground
input_parse: '[' ground
input_parse: 'D' ground

input_parse is logging what tmux receives from the terminal, in this
case it is "cat" printing "^[^[[D".

So the additional ^[ was sent to the terminal, and cat echoed it.

When I say terminal here I mean the pty inside tmux pane of course, not
the terminal emulator outside tmux.

Makes perfect sense. However, since I get ^[[D or ^[OD in cat, where did
KEYC_ESCAPE go? Shouldn't I be getting ^[^[[D or ^[^[OD instead? What am
I missing here? It looks to me that I'm pressing Alt/Option+Left in the
terminal but the app is receiving just a Left, and the Alt went missing.

I re-checked and you're totally right; my memory failed me.

Thanks for your patience in explaining this. Now I have a much better
understanding of the key translation behavior performed by tmux.

(I also found it weird that kLFT3 is compiled in the binary terminfo
database and "infocmp -x" doesn't show it, but that's off-topic for this
list.)
