hmmm there's two? https://github.com/NixOS/nix/pull/9054
https://github.com/NixOS/nix/pull/8778

also might depend on parser work..... anyway. filing this nonetheless.

OK plan devised on matrix with @lunaphied and @puck: simply statically or shared-link the rust side of nix-doc, which we compile with nix, into nix, to avoid fucking with the make build system. Then invoke it with :doc in the repl.

This is a very silly solution because it is literally adding a second Nix parser to Nix, but it is an extremely easy win with extremely deletable code (the API surface we use is two functions) when we solve it properly and basically no actual disadvantages aside from being ugly.

Implementation steps:

  • Yoink lf-/nix-doc into a subdir in here
  • Make this into a staticlib output, build it with nix: fff1c0b3cc/plugin/src/lib.rs (L1-L20)
  • Tree-shake the entire rest of the program into nothingness
  • Static link our forked nix-doc in lix
  • Make :doc in repl invoke this function.
  • Write some tests
