Re: [PATCH] gnu: Add inklingreader

[Ricardo Wurmus]

Hi Roel,

thanks for the patch!

I wonder if the inklingreader could be added to an existing module.
Maybe ‘graphics.scm’?

Nitpick: end the summary line with a period ‘.’.

Normally, we write it like this:

> * gnu/packages/inklingreader.scm: New file.
> * gnu-system.am (GNU_SYSTEM_MODULES): Add it.

If adding to an existing module it would be something like this:

> * gnu/packages/graphics.scm (inklingreader): New variable.

You should be able to use “mirror://gnu/” here.  I don’t know the exact
URL, though (and I haven’t tried yet).

What does this do?  (I’m just curious.)

Inputs that are only needed at build time should be added to
‘native-inputs’ instead.

Please do not put an empty line here.

Since all software in Guix is free software you should not mention this
here again.

I wonder about the Inkscape plugin: does it work out of the box with our
inkscape package?

A very nice first contribution!  Thank you again.
(I’ll let others comment on this.)
