Hello, here is mcomix.
I tested it with zip, CBZ, 7zip pdf files, and a directory with normal
images, they all work fine.

I also tried unrar, but couldn't extract any archive with it, neither
through mcomix, nor manually through the commandline tool, so this might
be a separate problem.

I'm yet to actually test running the application. Will do so and get
back in a while. Meanwhile, other changes.

You can remove the comment. It's more or less obvious from the
'arguments' section that mcomix needs python 2.

These are inputs not propagated-inputs. propagated-inputs are only
required for python libraries. For python applications such as mcomix,
the executable gets wrapped in a script which sets the correct
PYTHONPATH variable. Look at $out/bin/mcomix and $out/bin/.mcomix-real

Also, is the gtk+ dependency required? mcomix seems to build and run
fine on my system without it.

Please make this "MComix is a ... ". See
https://www.gnu.org/software/guix/manual/html_node/Synopses-and-Descriptions.html

> +    (license license:gpl2)))

This should be license:gpl2+. When no license version is explicitly
specified in the source headers, it is of the "or later" variant. See
https://lists.gnu.org/archive/html/guix-devel/2017-02/msg00026.html

Also, add a copyright header for yourself at the top of the source file
(gnu/packages/image-viewers.scm in this case).

No, I think a short comment behind or above the #:python keyword is
necessary, in case someone in the future wonders "Hey, why do we package
this for python 2 only and not for python 3" even if both languages are
developed in parallel.

Ok, it doesn't hurt to keep the comment. Let's keep it.

Instead of mentioning p7zip, unrar and mupdf in the description, it
would be better if we could make them inputs and patch all references to
the executables in the source with their absolute paths. Could you try this?

I could try that, but mupdf is a pretty heavy dependency. guix size says
it's self-size is 208MiB and total-size is 491MiB.
I personally never needed it with mcomix, so I like that it is optional.
Is there some way to define a package with optional inputs?

For now I'm appending my WIP that should address your previous remarks.

As far as I understand, there is no way to specify optional inputs
(yet?). Here are two of many threads discussing this.

https://lists.gnu.org/archive/html/guix-devel/2014-11/msg00549.html
https://lists.gnu.org/archive/html/guix-devel/2015-05/msg00379.html

If mupdf is a heavy dependency and it is not commonly needed, you can
drop it and just package with 7z and rar as dependencies.

Sort these inputs alphabetically, as I mentioned in the crawl thread.

LGTM, otherwise! Please send an updated patch. Thanks!

I have successfully patched in the path for 7zip.
I init the variable that stores it with a unicode string. I make the
assumption that the store path will never contain a ' character.


I read a little bit about unrar and it's issues with mcomix.
Unrar is very old and only supports RAR2, as someone says in the mcomix
issues it is unable to unpack most rar archives created after 2002¹. On
other distro mcomix currently relies on an unfree rar package², and
there is an open ticket³ about switching to a free library like
libarchiver (which supports RAR5 and is also used by file-roller, which
works fine on GuixSD).

I tried unrar on the commandline and it would list file names, but
always fail on unpacking. When called by mcomix, it would always try to
read a password from stdin and freeze the gui.
I will omit rar support for now, since unrar is mostly useless.

Since these modules are already in alphabetical order, it would be good
to keep them that way. Insert (gnu packages python) at an appropriate
position.

Please put these in alphabetical order too. That means p7zip will go on
the top.

Can we move the information about RAR and PDF support to a comment above
the package definition, as done for the octave package?

Oh... this could be why zathura-cb has massive issues with most .cbr comics
I have! I had some ideas, but thanks for explaining this issue.
