2018–2022 · Dependency vendoring and test infrastructure

This period focused on consolidating the build environment by vendoring external Erlang dependencies and updating Rebar3 to version 3.27.0. The work also significantly expanded the test suite by adding Common Test hooks for faster debugging and comprehensive coverage for core components like the compiler and alias system.

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 034af23383 — 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.
