plugins/ccc: Add more settings

[jukremer]

I tried to add more settings to the plugin with suggestions by @GaetanLepage.

checks failed with this error:

Please help me figure out what I'm missing.

checks failed with this error:

This error occurs because ccc has not been declared previously in the lua config. What you can do is seting callSetup = false;. This will disable the calling of the setup function by helpers.mkNeovimPlugin. Then, you can do the following:

callSetup = false;
extraConfig = cfg: {
  extraConfigLua = ''
    ccc = require('ccc')
    ccc.setup(${helpers.toLuaObject cfg.settings})
  '';
};

So just put this at the end of ccc.nix? Why didn't this error occur last time?

Yeah

Why didn't this error occur last time?

Last time you weren't referencing ccc as a lua variable.

When you use (e.g.) ccc.input.rgb you're assuming the lua variable ccc exists and is in-scope.

Gaétan's suggestion is to ensure ccc = require('ccc') before calling setup.

Without disabling callSetup, it is called automatically without first defining ccc.

If we had something like an extraConfigLuaPre then the fix could be simpler.

We do have that I think?

We do have [extraConfigLuaPre] I think

We have a module option, but I can't see a parameter in the mkPlugin functions.

Not saying we need one though, just that this specific scenario would be simpler with it.
