This prevents a ".el.el" extension for source files with no version number in
their file name.

* guix/build/emacs-build-system.scm (store-file->elisp-source-file): Remove
  ".el" extension from file name before splitting to name and version.

LGTM!

BTW, for all this patch series, please make sure

  make check TESTS=tests/lint.scm

still passes.

What about simply:

  (string-prefix? (string-append (package-name package) "-"
                                 (package-version package))
                  file-name)

?

That’s a bit stricter but I think that’s what we expect.

Thanks,
Ludo’.

This will break all those emacs, python, etc. packages that have
"emacs-", "python-" prefixes in the package-name, but not in their
source file names. We'll have to add the file-name field to practically
every Guix package. I'm not sure this is a good idea.

Couldn't we drop patch 3, and just use patch 4 to fix this bug?

Oh right, my bad.

Well patch 3 is OK after all, if you want to push it.

As for the patch 4, I prefer to let Alex reply!

Wow, I don't know if removing ".el" from a file name can be written in a
more simple way, but the point of the patch is great!  I didn't realize
this problem could be fixed so easily.  It looks good to me, thanks!

It sounds like I'm considered to be an expert in that part of code.
Thanks, but note that it's Federico who wrote emacs-build-system, and
it's David who wrote the code that Arun is modifying with this patch.

Well, I mean I know something about emacs-build-system and what the
topic problem is, but it's too much credits for me :-)

Well, it will not "break" the packages, it will just add many new lint
warnings.  But I agree that the Ludovic's version is too strict.

What I would prefer is to make this linter check for "name-version" (or
for "name" and "version" separately) inside a source file name (not with
'string-prefix?', but with 'string-match'), so that the store file names
will look like this:

  foo-0.1.tar
  emacs-bar-0.2.el

and not like this:

  v0.1.tar
  emacs-bar.el

> Couldn't we drop patch 3, and just use patch 4 to fix this bug?

I think so, patch 4 is definitely a fix for the original problem, while
a general file-name linting is probably for another thread.

Pro tip: (string-drop-right …) can be replaced by:

Looks like I made a mistake with patch 4's commit message. I should have
used the prefix "build-system: emacs:", instead of "build:
