# Hooks for prek (https://prek.j178.dev/). See README for setup.
#
# Same shape as the sibling repos, minus what this one has no files for:
# no terraform (infra's), no prettier or astro (headquarters' web), no ruff
# (arena's Python helpers, and there is no Python here).

# The commit-msg hook needs its own git shim, so `prek install` alone does not
# get it. Naming it here means a plain `prek install` installs both.

# check-xml earns its place on one file, bridge/log4j2-quiet.xml, which
# nothing else parses until MegaMek refuses to start. check-yaml and
# check-json are here for the CI config this repo does not have yet; they cost
# nothing while they match nothing.
#
# check-added-large-files matters more here than in the sibling repos: the
# built database is 100MB and the bridge's dumps are 33MB, and while
# .gitignore covers them by name, a differently-named copy would sail in.

# The crate graph this repo's design rests on: no I/O dependency may reach the
# crates that have to compile to wasm, and no producer of ComputedStats may
# reach helm-db. Both erode by adding one line to a Cargo.toml, and the
# failure surfaces much later as "why can this not compile to wasm", so the
# trigger is Cargo.toml rather than every Rust file - a `use` cannot add a
# dependency, and this way the hook stays off the common path.
