Now that there’s a new ‘set-emacs-load-path’, I suspect this phase can
be removed.  Can you confirm, Maxim?

Please add short comments explaining what’s going on in these phases.

I would add this, taken from their README:

  Any readable Lisp value can be stored as a value in EmacSQL, including
  numbers, strings, symbols, lists, vectors, and closures.  EmacSQL has
  no concept of @code{TEXT} values; it's all just Lisp objects.  The Lisp
  object @code{nil} corresponds 1:1 with @code{NULL} in the database.

Otherwise LGTM, thanks!

Hello Ludovic,

Thank you for review!

I've applied all your suggestions except ‘set-emacs-load-path’.  First
of all this procedure is not exported.  Another pitfall is ‘Invalid
keyword’ error.

I've fixed all linter warnings reported by this command:
--8<---------------cut here---------------start------------->8---
./pre-inst-env env GUIX_PACKAGE_PATH= guix lint $(PAGER= git log --oneline | head -n 6 | cut -d ' ' -f 4 | sed 's/\.//' | tr '\n' ' ')
--8<---------------cut here---------------end--------------->8---

Also I've tested an Emacs ‘epkg-list-packages’ procedure inside:
--8<---------------cut here---------------start------------->8---
./pre-inst-env env GUIX_PACKAGE_PATH= guix environment --no-grafts --ad-hoc emacs-epkg emacs
--8<---------------cut here---------------end--------------->8---


I could push a set of patches without ‘set-emacs-load-path’.  WDYT?

Oleg.

Replacing ‘gnu-build-system’ with ‘emacs-build-system’ does the job.

Pushed as:

452454e30 gnu: Add emacs-epkg.
93aba854d gnu: Add emacs-closql.
4d089b5e5 gnu: Add emacs-emacsql.
6c92b4406 gnu: Add emacs-finalize.
5b6d67476 gnu: Add emacs-cl-generic.
086bfb37a gnu: Add emacs-pg.

[…]

I'll close the bug report.

Oleg.

Phases are typically not exported individually, but as an alist of all
the phases of the build system, as `%standard-phases'.

As `set-emacs-load-path' is a phase itself, it expects to be called as
such, with keyworded arguments. It would be simpler to just insert the
phase as in:

--8<---------------cut here---------------start------------->8---
;; Add this to the define-module top level definition:
;; (define-module (gnu packages emacs)
;; ...
;; #:use-module ((guix build emacs-build-system) #:prefix emacs:)
;; ...

(add-after 'patch-elisp-shell-shebangs
           (assoc-ref emacs:%standard-phases 'set-emacs-load-path))

Actually, you don't want to import this at the top-level of the
emacs.scm module but rather specify the import using the #:modules
argument passed to the build system. Here's a complete example (not yet
merged in master, currently under review):
