builder

Nix language interpreter.

Trying it out

Currently rix is not published anywhere, so you'll have to build it yourself. Please follow instructions in CONTRIBUTE.md on how to build and run rix.

Keep in mind that rix is still in development and many features are not yet implemented.

Notable design choices

Rix transpiles Nix expressions to JavaScript and evaluates them with V8. The idea is to leverage all the great work in the JS ecosystem (such as debuggers, fast JIT compilers, profilers, libraries, compiled code caching, and source mapping just to name a few).

Progress

  • 🌕 stage 0: evaluate basic expressions, rec attrsets, let bindings, with statement, functions

  • 🌕 stage 1: lazy evaluation

  • 🌘 stage 2:

    • 🌘 built-in functions (progress: 7 out of 113)
    • 🌑 derivations (hello world derivation)

  • 🌑 stage 3: full implementation (all derivations in nixpkgs, nice error messages, etc.)
