kjnilsson/fez

This system is a compiler and toolchain that translates F# code into executable Erlang/BEAM bytecode. It provides a CLI interface to initialize projects, parse F# source code, and generate Erlang Core AST, while also supplying a standard library of F#-style functional programming constructs and Erlang interop primitives like messaging and process management. The project includes build automation and test suites to verify the correctness of the F# to Erlang translation.

About this page

  • The description of this project is derived from its own commit history, not from its README.
  • The score is its highest published measurement, taken on 1 August 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
  • Measured at commit 0073033768 — the exact code this score is about.
  • Scored under rubric rubric-2026.08.18. Score the same commit under that rubric and you get the same number.
