Could you open an issue with the upstream maintainer asking them to tag a
release so that we could use the upstream release tarball directly
instead of relying on ELPA's tarball?

Hm, but this ELPA tarball is the release itself, no?

I thought it would be better if we could get the release tarball
directly from upstream (https://github.com/ch11ng/exwm).

Let's not wait for upstream. If they do release a tarball, we can always
update the source URI later. For now, could you please send another
patch set with the upstream git checkout as source? Thanks!

Please send the new patch set to this bug report. I'll close the other
one opened for the emacs-xelb patch.

Could you put the home-page just before the synopsis as commonly done
in other package definitions?

Please make this "@code{emacs-xelb} is a pure Emacs Lisp implementation
of ...". No need to repeat "X protocol Emacs Lisp Binding" as it is
already mentioned in the synopsis. Expand Elisp -> Emacs Lisp.

Remove "some". It makes the whole sentence sound vague.

Same about home-page.

Append "-checkout" at the end of file-name just like you did for
emacs-xelb.

LGTM, otherwise!

Sadly, I have found that I can not let exwm work well in guixsd, maybe
it is exwm's bug, but it surely beyond my ability, the below is my
lastest patch, which may be useful for future ...

Sorry to hear that. If you need any help, please feel free to ask here
or at help-guix@gnu.org. Your patches look good. I'll push them with a
few minor modifications once Ludo gives the green flag.

Thanks!

I need to debug and contact with exwm's developer, exwm is a powerful wm, maybe it is more powful and easy use than stumpwm with other emacs packages help,  in my personal opinion,  guile-wm just a toy project.

I have found the reason: https://github.com/ch11ng/exwm/issues/213

exwm need DISPLAY is ":0" instead of ":0.0", I don't know the reason.

The below is my updated patch, which changes a lot, so review is need again:

You should be able to do this just using #:make-flags. See
https://www.gnu.org/software/make/manual/html_node/Overriding.html

> +    (inputs `(("xcb-proto" ,xcb-proto)))

xcb-proto is only required during build time, right? Therefore, it is a
native input.

> +    (propagated-inputs
> +     `(("emacs-xelb" ,emacs-xelb)
> +       ("xhost" ,xhost)

Instead of making xhost and dbus propagated inputs, we should just
reference the required executables with their absolute paths. That way,
xhost and dbus would become normal inputs.

Use the keyword argument `inputs' here, instead of directly using `%build-inputs'.

Let's not call this a "Demo". Better to just use name, synopsis, etc. as
done for the xmonad package.

"all" is the default target, isn't it? In the interest of brevity, you
can drop it.

There should be two spaces after the full stop '.' at the end of a
sentence. Do run through 'guix lint'. It will warn you about this.

This comment is only for emacs-xelb, and shouldn't be here, right?

Everything else LGTM. Please send one last patch set. There may be a few
more minor corrections. I'll make them and push. I'm eager to try out
exwm. I didn't know about it before your patch. Thank you! :-)

Can we drop the -q flag? If we use the -q flag, the user's ~/.emacs is
not loaded. That means to use their editor, they'll have to start
another emacs process leaving the first emacs process just for
exwm. This need for two emacs processes is not nice.

This eval forces the user to put all exwm specific configuration in
~/.exwm.el. Is it possible to work out some way to let the user keep all
their configuration in the usual ~/.emacs, but still have some way for
the default configuration to work out of the box without the user having
to modify their ~/.emacs ?

exwm config can not enable when user use another wm, so in my opinion, putting exwm config in. emacs 
need emacs user do many work to avoid confilt

maybe adding (load ".emacs") to .exwm.el is a more simple

exwm-default-session is for exwm beginner or tester, 
in my opinion

by the way, loading "~/.emacs" seem to no problem,  just slower ,  without loading "~/.emacs" suit for test and debug exwm or show exwm to new users.

bug#26454: [PATCH 2/2] gnu: add emacs-exwm

[Arun Isaac]

I have finished all corrections. And, as far as I can tell, exwm builds
and works fine. If there are no other suggestions, let me know, and I'll
push.

In the patch I just sent, I check if the 'exwm feature is loaded. If it
is not loaded, then a default configuration is loaded. Else, nothing
happens and we proceed assuming the user has configured exwm in their
~/.emacs. This way, we get a working exwm out of the box and at the same
time, retain the user's ability to customize their exwm easily.

Though upstream prefers we use the pregenerated source code, I'm afraid
we cannot do that. All Guix packages are strictly built from source. For
now, there is no problem with our own regenerated source code. And, I
don't anticipate there will be many problems in the future. If and when
there is a problem and the package breaks, we will report the problem
upstream as a bug, and take any necessary action to fix our
package. Until then, this should be fine.

I've made many other minor edits and a little code restructuring. Please
go through the patch. I had to move the synopsis field up to the top of
the package definition so that I could reference it later while creating
the .desktop file.

Also, I've switched back to the ELPA tarball.

There seem to be some exwm upstream bugs with floating windows. Apart
from that, it works great. I have switched to exwm from my previous
window manager, dwm. :-)

I guess you can go ahead.  Thanks for finalizing it!

Makes sense to me.

I forgot to mention. In the spirit of sticking to the filenaming scheme
of other configuration files like ~/.emacs and ~/.gnus, I made ~/.exwm
the exwm configuration file instead of ~/.exwm.el.

Do you have the gnupg gtk pinentry working in exwm? This is the one
floating window I'm having trouble with. It immediately vanishes soon
after appearing. So, I can't enter my passphrase, and therefore can't
access my private key. I am using the tty pinentry until I can figure
out a solution to this problem.

The patch looks good to me, but if you say that the package is actually
non-functional, then including it as is may not be very useful, except
if these are upstream bugs maybe.

Minor thing: I’d suggest using the regular stanza for the
commit/revision number (info "(guix) Version Numbers").

Maybe add a comment like “Generate .el files from the XML description of

(zero? (system* "make" "all")) and remove #t.

Sounds like a lot of fun.  :-)

Arun: I don’t have anything to add.  I think you could at least commit
the first one.  Dunno about exwm proper; maybe it’s not worse than
Guile-WM anyway?  ;-)

Thanks,

That would effectively mean we don’t have the source code for this,
which would be a problem.

What about generating it, and if we do find differences compared to the
pre-compiled xcb-proto.el, then we can keep it in mind and report any
issues upstream?

Thanks,
Ludo’.

In the latest version of the patch, we are regenerating the sources from
xcb-proto. So, this issue has been addressed.

Also, could one of the Guix maintainers comment on the following?

emacs-xelb (https://github.com/ch11ng/xelb) provides a Makefile to
generate source code from xml files in xcb-proto. However, this source
code is already pre-generated and included in the upstream git
repository. Should we regenerate this code from xcb-proto afresh?

It would be nice, yes.  I suppose the tool to generate this is in their
repo?

Yes, el_client.el in the xelb repository does this.

@Feng Shu:

In your new patch, could you add a phase for generating this code from
the xcb-proto xml files as well? Thanks!

What I meant is that the tarball on ELPA is the upstream release itself!
ELPA packages are made by the upstream persons, so I bet it is ch11ng
who uploaded that tarball to ELPA.  So insist that ELPA tarball is the
right source and we should use it :-)

Actually, ch11ng does mention here (https://github.com/ch11ng/exwm/wiki)
that the project is dual-hosted on Github and Savannah. So, I'll switch
to the ELPA tarball before pushing. Thanks.

Could you open an issue with the upstream maintainer asking him to tag a
release so that we could use the upstream release tarball directly
instead of relying on ELPA's tarball?

Also, for future reference, when you are sending a patch series, first
open a bug report by mailing guix-patches@gnu.org, and then send the
patch series to NNN@debbugs.gnu.org, where NNN is the newly created bug
number. This way, all patches will show up in a single bug report and be
easier to review and apply.

See https://lists.gnu.org/archive/html/guix-devel/2017-02/msg00627.html

If exwm's config put ~/.emacs,  emacs will not start properly in other
desktop environment. user should hack and let exwm's config not
enable when current wm is not exwm, I don't know how to deal with this
problem.

If possible, I suggest to do like this, user can use ~/.emacs or ~/.exwm.el
to config exwm. if one need to switch different wm frequently,
~/.exwm.el may a better solution
