Message #5 received at submit <at> debbugs.gnu.org (full text, mbox):
Hi,
This is a follow-up of bug#46016 [1] and I think close it.
Now, it is possible to use ProofGeneral as any other Emacs packages. For
instance,
guix shell emacs proof-general coq
emacs foo.v
For now, the dependency of 'coq' is removed as with many Emacs packages.
Other said, the user has to provide such dependency. IMHO, it is the spirit
of such package where the 'prover' is let to the user (several are more or
less supported, see doc [2]).
Cheers,
simon

So, IIUC, the above is basically a hack: you disguise the main file into
an autoloads file because no autoloads file is generated from the code
base? If so, this might deserve a longer comment, IMO.
Otherwise, LGTM.

On a related note, what would be so bad about having to (require
'proof-general) interactively? Alternatively, we could in an after-
unpack phase add autoload cookies to the source file or write our own
autoloads altogether. WDYT?

Actually, my assumption was wrong. "proof-general.el" is
a meta-autoloads file:
;; This file is a thin, package.el-friendly wrapper around generic/proof-site,
;; suitable for execution on Emacs start-up. It serves two purposes:
;;
;; * Setting up the load path when byte-compiling PG.
;; * Loading a minimal PG setup on startup (not all of Proof General, of course;
;; mostly mode hooks and autoloads).

When not byte compiled, the file only does
(require 'proof-site (expand-file-name "generic/proof-site" pg-init--pg-root)))
I guess we could also provide a single autoloads file doing just that
or, according to the manual,
(load "PROOF-GENERAL-HOME/generic/proof-site.el")
> Alternatively, we could in an after-

Autoload cookies are already present in the code base, but in
sub-directories.
OTOH, I assume the solution proposed by Zimoun, as hackish as it is,
works well enough. And it requires less work. IMO, it is acceptable with
a good comment.

Yes. Note that ’proof-general’ was at one moment in its long history a
standalone package, i.e., running ’bin/proofgeneneral’ started Emacs and
launched everything. This had been removed long time ago [1] but the
current code inherits this long history.

Yes. The limitation comes from this subdirectory structure. This
breaks the usual way of packaging Emacs tools for Guix, IIUC.

From my point of view, my proposed patch appears to me the easiest fix.
If something is better, please let me know. :-)
About the comment, I thought « allow-subfolders-autoloads » and « Make
it visible by Emacs » would have been enough. ;-)
--8<---------------cut here---------------start------------->8---
(add-after 'install 'allow-subfolders-autoloads
(lambda* (#:key outputs #:allow-other-keys)
(let ((out (assoc-ref outputs "out")))
;; Make it visible by Emacs
--8<---------------cut here---------------end--------------->8---
Instead, I propose to extend to:
--8<---------------cut here---------------start------------->8---
(add-after 'install 'allow-subfolders-autoloads
;; Autoload cookies are present in sub-directories. A friendly
;; wrapper proof-general.el around generic/proof-site.el is
;; provided for execution on Emacs start-up. It serves two
;; purposes:
;; * Setting up the load path when byte-compiling pg.
;; * Loading a minimal PG setup on startup (not all of Proof
;; General, of course;mostly mode hooks and autoloads).
;; The rename to proof-general-autoloads.el is Guix specific.
(lambda* (#:key outputs #:allow-other-keys)
(let ((out (assoc-ref outputs "out")))
(copy-file "proof-general.el"
(string-append out ,base-directory
"/proof-general-autoloads.el")))))))))
--8<---------------cut here---------------end--------------->8---
Is it fine? If yes, I can send* a v2. Or please push directly. :-)
Cheers,
simon
*send v2: for the record, I do not have commit right. ;-)
