* doc/guix.texi (package Reference): Describe how packages that lack a release
or are pinned to an unreleased version should specify the ‘version’ field.
Add documentation for the ‘git-version’ procedure.
---
I am unsure if the format for packages that don’t have a release should
be ‘0.0.0-REVISION.COMMIT’ or just ‘0-REVISION.COMMIT’.

Thanks. 

I don't know if all should be included in the manual (though I think
the `git-version' function definitely should), but I'll comment it a bit
anyway.

  @samp{@var{VERSION}-@var{REVISION}.@var{COMMIT}} ... @var{VERSION}...

I think you should drop the "version 0" case altogether. I don't think
enforcing "0" or "0.0.0" does matter, and it adds noise to the
explanations.

  @var{REVISION}

I think you need to explain why bumping revision is needed.

Also, this is all specific to hash-based repositories. For example, SVN
uses monotonic revisions already, so none of the above applies to such
packages.

@var{COMMIT}

Here too, I think the special "0.0.0" case is misleading.

Maybe @lisp is more appropriate than @example.

Makes sense, users can probably that out on their own.

I am not familiar with SVN, but I will look into it.

Good point.

Changes since v1:
* Remove the case for “version 0”.

* Use @var{} instead of @code{} when appropriate, and @lisp instead of
  @example.

* Be more specific about what to set COMMIT to.  Git/Mercurial and
  SVN/Bzr should be handled differently.

The text LGTM, but I think “package Reference” is the wrong place for
it: it’s the reference, whereas the text above is a guideline.

The “Version Numbers” section under “Packaging Guidelines” already
touches this topic.  Perhaps we need to expand it and/or link to it from
“package Reference”, like:

  @item @code{version}
  The version of the package, as a string.  @xref{Version Numbers}, for
  guidelines.

The ‘git-version’ procedure could be documented in “Version Numbers”
too.

WDYT?

Thanks,
Ludo’.

Ah, I totally missed the “Version Numbers” section, it looks like it
already all the information I was looking for.  Since ‘hg-version’ was
just added, I will mention it as well.  :)

Linguistic nitpick: about ‘It works in the same was @code{git-version}’: ‘in the same was’
seems ungrammatical to me. Should this have been something like

   It works in the same way as @code{git-version}.

? (Remember to include the period.)

LGTM otherwise.

Greetings,
Maxime.
