Stop using post-link script in conda recipe

[eferreira]

Apologies if this has been discussed before. I noticed that the conda recipe for this project does quite a bit in the post-link phase. Namely it runs jupyter-contrib-nbextension install, which has the effect of copying a lot of files around and editing some other files in place.

I just wanted to discuss the feasibility of moving all this into the build phase of the conda recipe, and publishing the result as a conda package without any post-link script. For the files that are edited in place, this seems relevant: jupyter/notebook#3116. It should be possible to avoid needing to edit any existing files, and just create new files in *.d/ directories instead.

Has anyone tried this already? Is there some major reason that I'm missing why this wouldn't work?

Hi! No, no reason not to do it that I know of. I just I haven't had time to do anything to this repo for a while, so haven't looked into the new .d stuff. If you fancy dropping a pr, feel free :)

Seee the last part: https://conda.io/projects/conda-build/en/latest/source/link-scripts.html

If the last one is violated (Depend only on simple system tools such as rm, cp, mv and ln.) then there would definitely be pre-link and post-link.sh errors during environmet creation/removing.
