This plugin has a shebang with /bin/env instead of /usr/bin/env, so update the
patchPhase to handle both cases.
WARNING/TODO: Libreoffice says "General Error. General input/output error."
when I try to open the generated .fodp files. So the odt backend works fine,
but the odp backend does not.
I tested the previous "version" and found my environment to be exactly the same.
Let's start discussing possible extensions/improvements somewhere else. For now it's a nice improvement.
This change does two things:
* "NixOSizes" environment variables generation. This allows some more
error-checking and opens possibilities for a modular environment
configuration. From now on the most of environment variables are
generated directly by the nix code. Generating sh code that
generates environment variables is left in a few places where
nontrivial access to a local environment state is needed.
* By doing the first change this patch untangles bash from the
environment configuration and makes it trivial to add a support for
other non bash-compatible shells.
Now to the sad part. This change is quite large (and I'm not sure it's
possible to split it) and yet is not quite complete, it needs some
changes to nixpkgs to be perfect.
See !!! comments in modules/config/shells-environment.nix.
Main principle behind this change is "change environment generation
and nothing else". In particular, shell configuration principles stay
exactly the same as before.
Also, slightly change the shebang fixup in the patchPhase so that it
handles optional [[:space:]] before the interpreter path (needed for the
filters).
To enable the extra filters, put this in packageOverrides:
asciidoc = pkgs.asciidoc.override {
enableDitaaFilter = true;
enableMscgenFilter = true;
enableDiagFilter = true;
};
This didn't work reliably because it raced with the remounting of /.
So if you were unlucky, then / was read-only by the time we ran
"alsactl store". Now the sound card state is saved before anything is
unmounted/remounted.
