Are you sure the Perl XML modules are needed at runtime and not at build
time (to build doc, for example?).

> +           python-numpy

If python-numpy is refered at runtime, you'd need to also add
python-wrapper as an 'input' I believe, since numpy is a Python
library.  One good way to verify if the dependencies are correct is to
run the package in a container with:

$ ./pre-inst-env guix shell -C plplot

and see if something fail.

Another telling data point to shake extraneous dependencies is looking
at the output of 'guix gc -R $(./pre-inst-env guix build plplot)'; if
python-numpy is not there (probably it isn't), but really needed at
runtime, then it'd need to be wrapper in the plplot command script.

Could you verify that the package works in a container, adding a wrap
phase if needed or removing the unneeded inputs?

Thanks!

I forgot to mention, the description appears to be truncated.  It'd also
be nice if it contained a bit more information to help users
differentiate it from other plotting libraries.

Thanks again,

Hi Maxim,

Thanks for feedback, it's my one of the long pending package to Guix
due to it's complexity.
I initially followed packaging approach which Debian had but some of
the large projects are not packed yet (ADA for example) so it's
simplified version with less bindings.

It's required for some other astronomical software depending on it.

Regards
