zathura: improve overridability; set plugin dir through the environment The current package setup has two issues: * You can only access `pkgs.zathura` which is the "final" derivation, i.e. a wrapper. This is a problem if you want to apply a patch to `zathura(1)` in an overlay. To make this a bit easier, I decided to expose `zathuraPkgs` entirely and `zathura` is now `zathuraPkgs.zathuraWrapper`. With this change, patches can now be added like this: ``` with import ./. { overlays = [ (self: super: { zathura = super.zathura.override { zathura_core = super.zathuraPkgs.zathura_core.overrideAttrs (_: { patches = [ ~/Projects/zathura/0001-Fix-remote-link-resolution-in-zathura.patch ]; }); }; }) ]; }; zathura ``` * As soon as you open another window in `zathura` from `zathura` (e.g. to follow a PDF-embedded link to another PDF), it currently fails because `--plugins-dir=` isn't passed along. This is because `zathura` uses `argv[0]`[1] to open another process and the GApps-wrapper inside `zathuraPkgs.zathura_core` does a `exec -a "$0"` which isn't the `bin/zathura` from the wrapper that appends `--plugins-dir=`: ``` execve("/nix/var/nix/profiles/per-user/ma27/home-manager-140-link/home-path/bin/zathura", ["/nix/var/nix/profiles/per-user/ma27/home-manager-140-link/home-path/bin/zathura", "/home/ma27/Documents/Uni/Studium/Notepad/Aktuell/Index.pdf"], 0x7ffd7a4bf4b0 /* 108 vars */) = 0 execve("/nix/store/2wjhxbgzcnn0qqdwqy0m01hw39dxwfmk-zathura-0.4.8-bin/bin/zathura", ["/nix/store/2wjhxbgzcnn0qqdwqy0m01hw39dxwfmk-zathura-0.4.8-bin/bin/zathura", "--plugins-dir=/nix/store/wcch63yzwykc9x5393dzjfdxsf80mrb8-zathura-with-plugins-0.4.8/lib/zathura", "/home/ma27/Documents/Uni/Studium/Notepad/Aktuell/Index.pdf"], 0x1442010 /* 107 vars */) = 0 execve("/nix/store/2wjhxbgzcnn0qqdwqy0m01hw39dxwfmk-zathura-0.4.8-bin/bin/.zathura-wrapped", ["/nix/store/2wjhxbgzcnn0qqdwqy0m01hw39dxwfmk-zathura-0.4.8-bin/bin/zathura", "--plugins-dir=/nix/store/wcch63yzwykc9x5393dzjfdxsf80mrb8-zathura-with-plugins-0.4.8/lib/zathura", "/home/ma27/Documents/Uni/Studium/Notepad/Aktuell/Index.pdf"], 0x81d010 /* 108 vars */) = 0 ``` I figured it's way simpler to actually use the environment variable `ZATHURA_PLUGINS_PATH` for that purpose as the environment is inherited when a new process is started.
