Hello everybody, What's the best way to send configuration parameters to Nix expressions?
Say I have a tool (a bash script) that dynamically generates nix expressions based on other runtime factors. I can use the sed tool to find/replace some properties inside the `x.nix` files. But this can become a mess of unmaintainable regular expressions. I would prefer to be able to instead write a config file with a standard schema, and then get Nix to import this, rather than using regular expressions. This could be JSON. But it could also just a be a file with a list inside it. I looked at the Nix Manual and found a few "builtins" functions. None of them seemed to be able to parse config or even a simple list in a static file. I saw there was a toJSON and toXML, why not fromXML or fromJSON, or even just fromFileList or some functions that can parse text. Barring that, perhaps is there a Nix expression parser that can be dynamically used?
