[PATCH 0/1] Add poppler-with-data. |
|

Hi,
I would like to view PDF files in Japanese with a viewer such as Evince, but
it seems that it cannot render Japanese at present, so I wrote a patch.
As far as I know, in order for Poppler to render CJK text, one of the
following conditions must be met
1. Install poppler with poppler-data preinstalled.
2. Install poppler, then poppler-data in the path expected by
poppler. (`POPPLER_INSTALL_PREFIX/share/poppler`)
ref:
https://github.com/freedesktop/poppler/blob/277f5de9684b3392f0d585bd36ad1a5e9e9e9ed7/CMakeLists.txt#L348-L362
Guix provides poppler and poppler-data as standalone packages, but installing
both will not satisfy either of the above prerequisites.
So I defined poppler with poppler-data as a package with the name
popper-with-data.
This package is intended to be used in the installation of packages that also
have poppler as a dependency, as shown below.
guix package -i evince --with-input=poppler=poppler-with-data
However, As a user, this is still a bit of a hassle, so if you have a better
idea, I'd like to see it.
Incidentally, it seems that Nix had defined its own environment variable
(PLOPPER_DATADIR) to deal with this problem.
The usage of this variable seems to have been changed in the next commit, but
I personally thought it was a generic and useful way to deal with the problem.

If it is allowed to integrate poppler and poppler-data, that would be the
simplest solution.
Thank you.

Pushed to core-updates along with some other changes. You still need
to keep your own poppler-with-data around for some while, but it should
be fixed with the next merge, so I'll mark this as done :)
Cheers
