# Pre-commit Configuration for web_ui
# Install:  pre-commit install && pre-commit install --hook-type pre-push
# Run:      pre-commit run --config web_ui/.pre-commit-config.yaml --all-files

# NOTE: this subproject lives inside the ~/src/utils monorepo, whose git root is
# one level up. pre-commit always runs hooks from the git root, so every path
# below is written relative to THAT, not to this directory, and the top-level
# `files` key keeps these hooks off the sibling subprojects. CI invokes this
# config exactly the same way. Mirrors design_system/.pre-commit-config.yaml.
files: ^web_ui/
# dist/ is generated by tsc and committed for consumers. The whitespace hooks
# would "fix" it, the next build would revert them, and the dist-fresh hook
# would fail forever -- so formatting hooks must not see it.
exclude: ^web_ui/dist/
