Zathura packages are organized confusingly

[langston-barrett]

Issue description

With the following in my configuration.nix:

  environment.systemPackages = with pkgs; [
    zathura
    zathuraCollection.zathura_core
    zathuraCollection.zathura_pdf_poppler
  ];

When I launch zathura:

 zathura my-doc.pdf

I get the following error:

error: could not open plugin directory: /nix/store/2kr6n75x8yxqvnfgf75jr1z0lrzzp6y0-zathura-core-0.3.6/lib/zathura
error: Unknown file type: 'application/pdf'

And indeed, that directory doesn't exist:

/etc/nixpkgs > ls /nix/store/2kr6n75x8yxqvnfgf75jr1z0lrzzp6y0-zathura-core-0.3.6/lib 
pkgconfig
/etc/nixpkgs > ls /nix/store/2kr6n75x8yxqvnfgf75jr1z0lrzzp6y0-zathura-core-0.3.6/lib/pkgconfig
zathura.pc

However, when I install zathura with

nix-env -i zathura

everything works as expected.

Steps to reproduce

Install zathura with above config, try to open a PDF

You shouldn't install plugins into your system path. Instead, install just zathura -- it's a wrapper that installs zathura_djvu, zathura_ps and zathura_pdf_mupdf (or zathura_pdf_poppler if you pass useMupdf = false to it). Unfortunately we still haven't done so that you can choose plugins more granularly, but it can be trivially implemented if needed.

@abbradar Thanks for the clarification. Is there a way we could make this more readily understood for users?

[abbradar]

Hmm, I don't have much ideas. Maybe renaming zathuraCollection somehow would help?

[rasendubi]

I must say I haven't had an issue with Zathura. I've just installed zathura and expected it to work -- that's what actually happened.

We can change zathura's name to zathura-with-plugins (similar to rxvt-unicode-with-xxx and some other packages). Don't change attribute path, though.

Is there a reason to keep zathuraCollection in all-packages.nix at all? Sounds like an implementation detail to me.
