Print hook description on failure with --verbose by GhostofGoes · Pull Request #2353 · j178/prek

GhostofGoes · 2026-07-15T20:38:14Z

Summary

When --verbose (or the new PREK_VERBOSE environment variable) is enabled and a hook fails, prek now prints the hook's description field alongside the existing hook id/duration/exit code details. The goal is to help users understand why a hook failed without needing to dig through prek.toml/.pre-commit-config.yaml. This is opt-in, but could become default behavior in the future.

The PREK_VERBOSE env var lets this work for hooks triggered via Git (e.g. git commit) too, since Git has no way to forward CLI flags like --verbose to the installed hook shim.

Changes

crates/prek/src/cli/run/run.rs: print - description: ... after - hook id: ... when a hook fails and verbose mode (global --verbose/-v or per-hook verbose: true) is active.
crates/prek-consts/src/env_vars.rs: added PREK_VERBOSE env var, mirroring the existing PREK_QUIET.
crates/prek/src/cli/mod.rs: wired env = EnvVars::PREK_VERBOSE onto the --verbose arg and updated its help text.
crates/prek/src/cli/hook_impl.rs / crates/prek/src/main.rs: threaded verbose through hook-impl so hooks invoked by Git shims respect it.
crates/prek/src/config.rs: updated the description field doc comment to mention it's now surfaced on failure.
Docs: docs/usage.md, docs/authoring-hooks.md, docs/reference/configuration.md, docs/reference/cli.md (regenerated), and prek.schema.json (regenerated).

Tests

crates/prek/tests/run.rs: verbose_prints_hook_description_on_failure and prek_verbose_env_var_prints_hook_description_on_failure.
crates/prek/tests/hook_impl.rs: hook_impl_verbose_env_var_prints_hook_description, exercising the Git-hook (git commit) path end-to-end.

cargo fmt --check and cargo clippy --all-targets are clean, and the full run/hook_impl integration test suites pass locally.

Pull request overview

This PR extends prek’s verbose mode so that, when a hook fails, prek prints the hook’s configured description alongside the existing failure details. It also adds a PREK_VERBOSE environment variable to enable the same behavior for Git-triggered hooks (e.g., git commit), where CLI flags can’t be forwarded to the hook shim.

Changes:

Print - description: ... on hook failure when verbose mode is enabled (CLI --verbose/-v, per-hook verbosity, or via PREK_VERBOSE for Git hook shims).
Add PREK_VERBOSE env var support and thread verbose through the hook-impl execution path.
Update schema/docs and add integration tests covering both prek run and Git-hook (hook-impl) paths.

When --verbose (or the new PREK_VERBOSE env var) is enabled and a hook fails, prek now prints the hook's `description` field alongside the existing hook id/ duration/exit code details. This helps users understand why a hook failed without needing to dig through prek.toml/.pre-commit-config.yaml. The PREK_VERBOSE env var lets this work for Git-triggered hooks too (e.g. `PREK_VERBOSE=1 git commit`), since Git can't forward CLI flags to the installed hook shim. Adds tests covering both `prek run --verbose` and the PREK_VERBOSE env var via a real git-hook invocation, and updates docs/reference/cli.md, docs/reference/configuration.md, docs/authoring-hooks.md, docs/usage.md, and prek.schema.json accordingly.
