Leanblueprint broken on Nix

Stream: general

[Niklas Halonen]

Hi all, I packaged leanblueprint to nixpkgs, but as pointed out by @Yury G. Kudryashov its plasTeX integration is broken, sorry about that. I'm working on a fix but won't promise that I get it done any time soon. Here are some more details about the problem if someone wants to help with the task:

• When creating a web version of the blueprint, plasTeX tries to use the leanblueprint python module, which it cannot find as it was built without leanblueprint as a dependency. This error is seen in the output

plasTeX version 3.1
..
ERROR: Loading package "report" raised exception ModuleNotFoundError : No
   module named 'leanblueprint'

• Adding leanblueprint as a dependency to plasTeX would cause a cyclic dependency resulting in "error: infinite recursion encoutered".

Some possible solutions I have considered:

• Rewriting leanblueprint to use plasTeX as a python module rather than call it from a subprocess
• Create a wrapper for plasTeX which has leanblueprint in its PYTHONPATH
• Creating a package which bundles leanblueprint and plastex into one

As far as I know there is no way to get leanblueprint to work on Nix right now. Please correct me if I'm wrong.

I'm setting the python path in the command line, then it works.

You can just create a wrapper around the lean blueprint command that sets the python path environment variable. On the phone, so can't give more details right now.
