ping @domenkozar @datakurre @cillianderoiste could you check that all info from above wiki pages is in nixpkgs manual.

I'm updating Python docs in #13320

• https://nixos.org/wiki/Python_discussion contains nothing interesting. Maybe we should write something about recursive pth loader
• https://nixos.org/wiki/Python is trivial. I'm including http://python-on-nix.readthedocs.org/en/latest/ in the docs which covers this article.

@FRidh Thanks. I was not aware of python-on-nix docs. Would've definitely helped earlier.

@garbas I'd just drop "Plone development" chapter for now, and replace it later with more generic "Buildout" development later.

@garbas, @cillianderoiste What should we do with various zc_buildout versions vs. zc_buildout_nix? Should zc_buildout_nix behavior be made the default? (And maybe an option to turn it off at will.) zc_buildout_nix is patched to always prefer packages from the current nix environment and made possible to e.g. properly build Plone in Nix until namespace packages broke with buildout due to wheels.

@garbas Here's the buildout namespace issue, which I mentioned: #12141

@Profpatsch if you close an issue, please motivate way.

I wonder, how many there are using buildout-based development with nix? @cillianderoiste? I have a team using nix with buildout but the current version of pythonPackages.zc_buildout_nix should just work.

@cillianderoiste I do have one more patch locally for my team for zc_buildout_nix:

    postInstall = ''                                                            
      sed -i "s|import sys|import sys\nimport os\nsys.executable = os.path.join(sys.prefix, 'bin', os.path.basename(sys.executable))|" $out/bin/buildout
      cat $out/bin/buildout                                                     
    '';

It fixes zc.buildout-generated scripts to have python interpreter with zc.buildout available. Of course, it does not prevent garbage collection of those envs. Maybe I should propose that as a patch for zc_buildout_nix...

@FRidh I batch-closed all wiki issues, after consultation with garbas. Feel free to reopen anything that is still relevant (or worked on).

Actually, I probably should shoot a mail to the discourse as well.

Nothing actionable here I think, so closing.
