using things like ${pkgs.example} in files pointed to with .source

[cyrneko]

hi! I am writing a configuration right now and I've found myself in a situation where I want to use ${pkgs.b612} to point to a font in the config for my text editor

One problem is that to do so, I had to write the config in nix by using the .text function, but that places a rather large .lua file in-between the definitions of all other things

I did consider just putting it into its own .nix file and importing it, but that's still not quite what I was hoping to do

What I was hoping to do, was being able to place things like ${pkgs.b612} into a file pointed at using .source and have it evaluate

ty for any help!!!

Maybe I'm not understanding exactly but I think the pkgs.replaceVars function may be useful in this case.

If you have a file b612-in.txt like so:

Here is b612: @b612@

Then you can make Home Manager produce a file ~/b612.txt with @b612@ replaced by the path of pkgs.b612 as follows:

home.file."b612.txt".source = pkgs.replaceVars ./b612-in.txt {
  b612 = pkgs.b612;
};

oh that is great! this would indeed cover my usecase; thanks a lot!
