Hi all,

First patch to guix-devel; tried my best to conform to the guidelines.
Couldn't fix some "abiguous package" issues with
font-adobe-source-code-pro package. Let me know if someone finds a
solution.

More packages to come!
Dylan

Hello Dylan,

Thanks for this patch! I love the source-code-pro font :).

Guix (usually) has a one commit per change policy. Contributions in guix
usually follow a specific format. You might want to review the
guidelines as specified in the manual, which one can find online or by
executing
  `info -f doc/guix.info "(guix) Contributing"`
in a guix git checkout.

I am not quite sure what "ambiguous package" issues you are talking
about. Are you referring to "collision encountered" warnings?


I added your patch inline with some observations;

Guix follows the CHANGELOG[0] format for commit messages. You can check the
commit history for examples of how to phrase certain common changes.

... and here you mention the source of these ttf files also being
available in the package (which you do not seem to install). Best case
scenario would be if we can generate the ttf files ourselves from these
sources. I had a brief look at AFDKO, and IMHO the build procedure seems
quite complicated. Right now, I would remove the part about the source
files and AFDKO from the description.

NOTE: I am not a pythonista, but could you not disable subset of the
tests that depend on many more packages? Or maybe elaborate a bit more
one why exactly testing this package is not worth it. See the
python-drmaa for example.

Something funky seems to be going on with the indention here. I usually
let emacs' scheme mode take care of the indentation for me using the
`indent-region` command. I assume the KIVY_SDL2_PATH is required for
kivy to build correctly?

You can join the previous two lines, so you get `(("python-cython <etc>

Guix and its packaged software are Free Software projects, and as such,
the 'open-sourceness' of this package are implied by the greater
implications of it already being Free Software.

Unless I am mistaken, Kivy is licensed under the "MIT" (Expat) license.

This means that you have more than one packages providing
font-adobe-source-code-pro.

This commit needs to be split up into two commits, and they need proper
commit logs in accordance with our conventions.  See section 8.5
(Submitting Patches) in the manual for details.  I also recommend
looking in the existing commit logs for examples.

The question of whether AFDKO is a free software project is unclear.
Even just downloading AFDKO from Adobe requires first accepting a EULA:

  http://www.adobe.com/devnet/opentype/afdko.html

There is a github project with some code in it, but it's not clear to me
whether it can be built and made functional without using non-free
development tools.  See:

  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=762252#25
  https://github.com/adobe-type-tools/afdko/issues/41

That said, this needn't be a blocker for including the built OTF files
in Guix, as long as the license permits all users to copy and
redistribute them for commercial and non-commercial purposes, as these
fonts are considered non-functional data.  See:

  http://www.gnu.org/distros/free-system-distribution-guidelines.html#non-functional-data

#:phases should be lined up with #:tests?.  The emacs package within
Guix includes a patch that fixes its Scheme mode to auto-indent this
properly, or see https://www.netris.org/~mhw/scheme-indent-function.el,
(or just fix it up manually).

Please add #t after the (setenv ...) call, as phase procedures are
expected to return a boolean indicating whether it succeeded, whereas
the return value of 'setenv' is unspecified.

We avoid the term "open-source", preferring the term "free software"
instead, but since all software in Guix is free, there's no need to
mention this at all.  So how about just "Multitouch application
framework"?

Can you post an updated pair of patches, in two separate emails?

And I meant, but forgot, to conclude this with:

For now, please remove the second sentence of the 'description' field
above, to avoid steering users toward AFDKO.

Are you sure about that? By my reading, that document explicitly
categorizes fonts as functional works by that document:

Personally, I have avoided submitting my font-iosevka [1] package for
months because it just downloads the ttf files instead of building them
from the JavaScript source code. (Maybe when we have better node
support, eh?)

You're right, I stand corrected.  This will require more investigation.

I don't know what the right answer is, but (gnu packages fonts) has
several font packages that simply download and unpack TTF files.

I was assuming that font editors typically operated directly on font
files, so there is no corresponding source. I guess that's not true
though, since FontForge operates on SFD files and Adobe apparently works
with AFDKO files. The question is do we need to built fonts from source?

I think we can package Source Code Pro either way. It looks like there
are two versions of AFDKO, a free software version on GitHub [1] and one
with non-free code on adobe.com.

P.S. Iosevka is really weird because it's actually built from JavaScript
code, and also because it tries to license the source under a BSD-style
license and the built artifacts under the SIL OFL. I don't really know
what to make of that.
