with-pgtk: C-; turns into plain ';'

with-pgtk: C-; turns into plain ';'

[T.V Raman]

After building from head today with --with-pgtk,

I've now lost keys such as C-;, C-, etc under X -- they just produce
the key minus the modifier bit, So c-; just generates ";". Bug or intentional?

Removing --with-pgtk from the config options and rebuilding got back
C-; and friends.

People running X should not use the PGTK port.  The only use it has is
to support Wayland and Broadway.

And it's not intentional.  Rather, it's a bug in the various GTK input
modules out there that isn't likely to ever be fixed.  Just treat it as
a limitation of the PGTK port and don't use it unless you have to.

Thanks.

Indeed, which is one of the reasons why people who don't have a specific
reason to use the PGTK port (such as Wayland) should not use it.

Is that the case for C-c, C-x and friends?

I.e. for "normal" letters?

Note that TTYs have no way to represent C-; and friends.

You ended up, perhaps, with a TTY build?

But they do.  It just takes a bit of work.  loadkeys is your friend.
I've had C-; on my Linux console for over 20 years, now.  As well as
loadkeys, you need to set up Emacs with stuff in the function-key-map to
handle the modified keys.  It works well.

OK, OK. I should have added "often" :-)

Usually it's me the one who says "all generalizations suck". Thanks for
setting me straight.

Still, and returning to the OP, the described behaviour is at least a
kind of hint: I'd check whether C-c and C-x works or not, to bisect the
issue at that point.

Indeed.  And similar solutions exist for xterm and friends.

Side note: the "right" way to do it is via `input-decode-map` rather
than `function-key-map`, BTW.

Ah, how these things change!  I think function-key-map was the only way

The NEWS entry seems fine (it already mentions that it's for Wayland and

Is that specific to certain desktop environments?

I have a PGTK build compiled here (rev 70c3437a), and 'C-;' seems to be 
working fine. Ubuntu 20.04, GNOME Shell under Xorg.

It's specific to certain popular input method modules.  If you have
disabled input method support, then C-; will work, but as expected the
input methods will not.

With XIM support on X, all of that will work fine.

Thanks.

IMNSHO, not explicitly enough:

  ** Emacs now supports being built with pure GTK.
  To use this option, make sure the GTK 3 and Cairo development files
  are installed, and configure Emacs with the option '--with-pgtk'.
  Unlike the default X and GTK build, the resulting Emacs binary will
  work on any underlying window system supported by GDK, such as
  Wayland and Broadway.

No matter how many times I re-read this, I fail to understand that it
tells me not to use it on X, and it definitely doesn't warn me of any
downsides if I do.  A word of warning is definitely in order there.

How about "the resulting Emacs binary is supposed to work with window
systems other than X that are supported by GDK, such as Wayland and
Broadway"?

I'd suggest something more explicit, like

  We do not recommend that you use this configuration, unless you are
  running a window system that's supported by GDK, such as Wayland or
  Broadway.  Running this configuration on X is known to have
  problems, like ...

(describe a couple of problems instead of the ellipsis).

Indeed, `function-key-map` used to be the only way.
I added `input-decode-map` in Emacs-23.

Yes, I would agree. 

This is likely going to be problematic. A number of GNU Linux distros
are now defaulting to Wayland (e.g. fedora) and others have flagged
tgheir intention to follow suit (Ubuntu, Debian). 

Where this could become problematic is if distro maintainers don't
realise there are downsides with a pgtk build under X. In this
situation, they are likely to only bundle a pgtk and non-GUI versions
rather than a pgtk, X and non-GUI versions. 

If we make the issues associated with pgtk, X and input methods
explicit, distributions which want to support wayland and X will be more
likely to include both wayland (pgtk) and X binary packages. 

As distributions which do support wayland typically also make it easy to
select/switch desktop environments, it is probably also important users
are aware of the input method issues with pgtk under X as it means that
when they switch from wayland to X, they also need to know to switch
which build of Emacs they run. Failure to adequately communicate this
will likely result in numerous unresolvable bug reports.

Yes, I think it needs to be this explicit. The suggested entgry from Po
Lu is still too oblique and fails to be explicit about known issues.
Something also seems "wrong" with a statement which includes "is
supposed to work".

I suspect if C-c and C-x did not work, that would already have been
reported as those are key bindings pretty essential to a functionaling
Emacs. A failing binding for something like C-; is something many users
may not notice for some time (if ever).

This is a very important point!

If you were running the pgtk build and all the key bindings were working
fine and then suddenly they stopped working, I would agree it it likely
there is something more going on than simply "a known problem with gtk
and input methods".Especially as it is unlikely you changed input
methods settings. It may be a mistake to just write this off as a "known
issue". Will be interesting if others running pgtk under X also start
noticing issues. 

While I'm not running the pgtk build at present, have to admit that when
I did a few months back, I did not encounter any key binding issues
under X. Have to admit, I didn't do anthing 'special' with input
methods. Just ran it under various X envrionments (Stumpwm, Ubuntu Matge
and a brief experiment with Exwm).

AFAICT, it's the same issue with "C-S-u" being reported as C-u on the
PGTK port, which has been there since the beginning (search the bug
tracker for more details.)

Disabling input methods using `pgtk-use-im-context' makes both problems
go away here for me, and none of that code has changed since it was
installed.

So if the problem only recently appeared for you in the PGTK builds,
please try to bisect to the change which introduced it.

Thanks.

Interesting, I'm using pgtk on wayland/sway and C-h k C-S-u doesn't
report anything but inserts an underlined letter "u" in the current
buffer, even when that is read-only, and still seems to wait for my key.
Then, emacs is inresponsive, C-g won't work, and I need to switch to
another window and back again.  At that point, the underlined u
disappears and I can interact with emacs again.

When I run (pgtk-use-im-context nil), the above problem doesn't happen
and C-h k C-S-u reports C-u translated from C-S-u.  However, I also
cannot insert characters like ` or ´ anymore.  Pressing the relevant
AltGr-key combo on my German Dvorak layout doesn't seem to be received
by emacs.  C-h k <AltGr-combo> doesn't receive anything.

So it seems like I can choose pest or cholera...

If you're using I-Bus, then that's the Unicode code-point input panel.
You can disable it by running:

  gsettings set org.freedesktop.ibus.panel.emoji unicode-hotkey []

Or removing the "Unicode code point" entry in the Emoji tab of
ibus-setup.

The reason C-g does not work and Emacs appears to be unresponsive is
that the input method filters out all keypresses and sends them to the
panel, and switching to another window serves to dismiss that panel.

That's expected, since those combinations are handled by the GTK input
method machinery.

It seems I'm not, that says "No such schema
“org.freedesktop.ibus.panel.emoji”".  I also don't have the ibus package
installed but I do have libibus upon which a lot of packages seem to
depend on.

I've tried looking for other schemas but didn't find some but of course
I'm not actually sure what I'm looking for:

--8<---------------cut here---------------start------------->8---
❯ gsettings list-schemas | grep im
org.gnome.desktop.datetime
org.gnome.gedit.plugins.time

❯ gsettings list-schemas | grep input

I don't know about the other input method frameworks.  Could you find
out which one you are using?

Thanks in advance.

I've searched a bit and found

  https://docs.gtk.org/gtk3/property.Settings.gtk-im-module.html

which suggests that the property gtk-im-module is the default input
method unless the user explicitly chose another im-module from the IM
context menu.

❯ gtk-query-settings | grep im-module
                      gtk-im-module: "wayland"

So it seems I'm using the wayland input method module.

Unfortunately that just means it's using the input-method-unstable-v1
Wayland protocol extension to handle input methods, and says nothing
about the framework being used.

In case it helps --

I was running the pgtk build on Debian until a few weeks ago -- and
 switched away after reporting a segfault -- should be in the list
 archives. Before that C-; worked in the pgtk build. I went back to
 try pgtk last week  an  now there is no crash but the keys as I

Hm, C-; works for me with the current master, and C-S-u triggers the GTK
Unicode input method.  Now I know at least what "that underlined u" is.
After C-S-u one can insert 4 hex-digits and then it'll be replaced by
the corresponding unicode character.

I've tried out commit 97b6907563ae9c96ebb97876ce0662c7f9d47535 from
December, 18th (shortly after the pgtk merge) in order to bisect but
there I get the very same behavior as with today's master.

I think that's GTK's IMContextSimple. What does "echo $GTK_IM_MODULE"
get you? Maybe you can try:

gsettings set org.gnome.settings-daemon.plugins.keyboard active false

I've only fooled with the edges of this stuff, but maybe something in
the above will get you there.

Just for context, I use fcitx, and my GTK_IM_MODULE is set to fcitx, and
with the recent Emacs changes (I'm also on Arch/sway/pgtk) I had to go
into the fcitx configuration and disable a bunch of previously-ignored
hotkeys that suddenly were being honored.

If I just knew which input method framework I'm using so that I could do
the same. :-)

Maybe gtk-query-immodules-3.0 gives a clue?

I unfortunately have no idea as to what might've changed.  Please try

Disabling the IM module is the equivalent of (pgtk-use-im-context nil),
except it takes effect for all applications.

So that's probably not your answer.

What if you set it to `simple'?  The legacy XIM input module is
considered obsolete by the GTK developers and is not actively developed.

The simple and XIM backends are built alongside GTK, so they are always
present.

Thanks.

Looking at the various options -- and boy are they bewilderingly many;-)
it might time for emacs to take a step back and collectively come up
with a couple of keyboard configurations for the GUI desktop, in a
manner analogous to what was done for the console many, many years ago
where eventually Linux came with emacs.kmap and emacs2.kmap -- I dont
think end-users, or even specific distros or going to figure this out
for emacs.

This whole thread also reminded me of ibus -- whose landing on Ubuntu a
few years ago broke C-SPC; I remembered only because I have a line in my
.xsession that kills ibus if it running.

Would you please try `simple' instead?  Also, that's the equivalent of
running (pgtk-use-im-context nil) inside Emacs.
