PROFILE
Kyle Butt
Kyle contributed targeted reliability improvements to the tweag/rules_haskell repository, focusing on build systems and environment management. He enhanced locale handling in Nix-based builds by ensuring the LOCALE_ARCHIVE environment variable was correctly propagated and canonicalized, addressing recent Nixpkgs requirements and preventing failures due to directory changes. Using Python and Starlark, Kyle’s changes improved the robustness of locale settings across diverse environments. Additionally, he implemented executable aliases for vendored Cabal packages, allowing stack snapshots to reference tools even when Hackage metadata lagged behind GHC releases. These updates reduced breakages during upgrades and streamlined developer workflows in both local and CI environments.

Feb 1, 2025February 2025 focused on stabilizing locale handling in Nix-based builds for rules_haskell. Delivered a bug fix that ensures LOCALE_ARCHIVE is correctly propagated to the haskell_cabal_library and haskell_cabal_binary build targets, and canonicalized the LOCALE_ARCHIVE path in cabal_wrapper.py to avoid failures when directories change. This change aligns with the Nixpkgs requirement to have LOCALE_ARCHIVE set, improving locale reliability across environments. The work is captured in commit 6dd476bd1d4e8578583ab92840fba5fa5c1cd345.
