Summary

Closes #1779

  • Add --all flag to prek uninstall that scans the hooks directory and removes every prek-managed hook (detected via is_our_script()), regardless of hook type
  • Without --all, behavior is unchanged: uses -t or default_install_hook_types, falls back to pre-commit
  • --all and -t are mutually exclusive (conflicts_with)
  • Suppress "not managed" / "does not exist" skip messages when --all is used, since iterating all hook types will naturally hit many non-existent ones

Tests

  • uninstall_all_managed_hooks: --all removes all prek-managed hooks
  • uninstall_all_no_hooks: --all exits cleanly when no hooks are installed
  • Ran mise run lint and confirmed no errors

@Tiryoh
Add --all flag to prek uninstall
b75acd4 
`prek uninstall` previously only removed the default hook types unless
`-t` was specified, which could leave other prek-managed hooks behind.
Add an explicit `--all` flag to remove every prek-managed hook from
`.git/hooks`, while keeping the default behavior limited to configured
hook types or `pre-commit`.

Also suppress skip messages during `--all` scans and add tests for
removing multiple hooks and for the no-op case.

Pull request overview

Adds an --all flag to the prek uninstall subcommand so users can remove every prek-managed Git hook shim in one go, addressing the longstanding UX gap where uninstall could leave other installed hook types behind.

Changes:

  • Add --all to prek uninstall, mutually exclusive with -t/--hook-type.
  • Implement --all behavior by iterating all supported HookType variants and removing those detected as prek-managed via is_our_script().
  • Add integration tests/snapshots validating --all removes multiple hooks and no-ops cleanly when nothing is installed.

File Description
crates/prek/src/cli/mod.rs Adds the --all flag to UninstallArgs and documents/conflicts it with --hook-type.

crates/prek/src/cli/install.rs Implements the uninstall --all logic and suppresses skip messages when iterating all hook types.
crates/prek/tests/install.rs Adds snapshot tests covering prek uninstall --all behavior.

Pull request overview

Adds an --all flag to the prek uninstall subcommand to remove all prek-managed Git hook shims (as detected by is_our_script()), while keeping existing uninstall behavior unchanged unless the flag is provided.

Changes:

  • Add --all to prek uninstall and wire it through CLI parsing to uninstall logic.
  • When --all is used, iterate over hook types and suppress “not managed” / “does not exist” skip messages.
  • Add integration tests covering --all uninstall behavior with multiple hooks and with no hooks installed.

Pull request overview

Adds an --all option to prek uninstall to remove all prek-managed Git hook shims, making it easier to clean up across hook types.

Changes:

  • Introduce --all flag for prek uninstall (conflicts with --hook-type) and plumb it through the CLI.
  • Update uninstall behavior to iterate all supported hook types when --all is set (and suppress “skipping” noise).
  • Add an integration test covering prek uninstall --all behavior and update CLI reference docs.

### [`v0.3.12`](https://github.com/j178/prek/blob/HEAD/CHANGELOG.md#0312)

[Compare Source](j178/prek@v0.3.11...v0.3.12)

Released on 2026-05-05.

##### Highlights

`auto_update.cooldown_days` is now available in both the user-level global
config (`~/.config/prek/prek.toml` on Linux and macOS, or
`$XDG_CONFIG_HOME/prek/prek.toml` when set; `%APPDATA%\prek\prek.toml` on
Windows) and project config. Set a user default for `prek auto-update`, then
override it per project when a repository needs a different update cadence.

```toml
[auto_update]
cooldown_days = 7
```

##### Enhancements

- Add global auto-update cooldown config ([#&#8203;2041](j178/prek#2041))

### [`v0.3.11`](https://github.com/j178/prek/blob/HEAD/CHANGELOG.md#0311)

[Compare Source](j178/prek@v0.3.10...v0.3.11)

Released on 2026-04-27.

##### Highlights

Hook entries now have an explicit `shell` option for shell snippets. Set
`shell: sh`, `bash`, `pwsh`, `powershell`, or `cmd` when an entry should be
evaluated by that shell; leaving it unset keeps prek's direct argv execution.

`prek auto-update` can now filter tag candidates before choosing an update.
Both options take glob patterns: use `--include-tag` to only consider matching
tag names, and `--exclude-tag` to skip matching tags such as moving tags or
prereleases.

##### Enhancements

- Add `auto-update --exclude-repo <repo>` to skip repos ([#&#8203;1983](j178/prek#1983))
- Add `auto-update --exit-code` to exit with non-zero on updates ([#&#8203;2002](j178/prek#2002))
- Add `auto-update --include-tag <pattern>`/`--exclude-tag <pattern>` to filter tags ([#&#8203;1984](j178/prek#1984))
- Adds an explicit `shell` hook option for entries that should run as shell source ([#&#8203;2004](j178/prek#2004))
- Make `--hook-dir` optional for hook-impl ([#&#8203;1989](j178/prek#1989))
- Skip shim warning when `--script-version` is missing ([#&#8203;1990](j178/prek#1990))

##### Bug fixes

- Install Ruby executable in gem bin ([#&#8203;2017](j178/prek#2017))
- Use dedicated Android npm package ([#&#8203;1982](j178/prek#1982))
- Use stable repo keys without breaking cached clones ([#&#8203;1995](j178/prek#1995))

### [`v0.3.9`](https://github.com/j178/prek/blob/HEAD/CHANGELOG.md#039)

[Compare Source](j178/prek@v0.3.8...v0.3.9)

Released on 2026-04-13.

##### Highlight

`prek auto-update` is now stricter about pinned revisions and more useful in CI.
It now keeps `rev` and `# frozen:` comments in sync, can detect
[impostor commits](https://docs.zizmor.sh/audits/#impostor-commit) when validating pinned SHAs,
and lets you use `prek auto-update --check` to fail on both available updates and frozen-ref
mismatches without rewriting the config.

Examples:

```console
$ prek auto-update

# updates revs and repairs stale `# frozen:` comments

$ prek auto-update --freeze

# writes frozen SHAs with matching `# frozen: <tag>` comments

$ prek auto-update --check

# exits non-zero when updates are available, a `# frozen:` comment is stale,
# or a pinned SHA does not belong to the fetched upstream refs
```

### [`v0.3.2`](https://github.com/j178/prek/blob/HEAD/CHANGELOG.md#032)

[Compare Source](j178/prek@v0.3.1...v0.3.2)

Released on 2026-02-06.

##### Highlights

- **`prek.toml` is here!**

  You can now use `prek.toml` as an alternative to `.pre-commit-config.yaml` for configuring prek. `prek.toml` mirrors the structure of `.pre-commit-config.yaml`, but TOML is less error-prone. Your existing `.pre-commit-config.yaml` will continue to work, but for new users and new projects, `prek.toml` may make more sense. If you want to switch, run `prek util yaml-to-toml` to convert YAML configs to `prek.toml`. See [configuration docs](configuration.md) for details.

  For example, this config:

  ```yaml
  repos:
    - repo: https://github.com/pre-commit/pre-commit-hooks
      rev: v6.0.0
      hooks:
        - id: check-yaml
  ```

  Can be written as `prek.toml` like this:

  ```toml
  [[repos]]
  repo = "https://github.com/pre-commit/pre-commit-hooks"
  rev = "v6.0.0"
  hooks = [ { id = "check-yaml" } ]
  ```

- **`serde-yaml` has been replaced with `serde-saphyr`**

  We replaced the long-deprecated `serde-yaml` crate with [`serde-saphyr`](https://crates.io/crates/serde-saphyr) for YAML parsing. It is written in safe Rust and has better error messages, performance, and security. This lets us provide precise location information for configuration parsing errors, which should make it easier to fix config issues.

  For example, this invalid config:

  ```yaml
  repos:
    - repo: https://github.com/crate-ci/typos
      hooks:
        - id: typos
  ```

  Before:

  ```console
  $ prek run
  error: Failed to parse `.pre-commit-config.yaml`
    caused by: Invalid remote repo: missing field `rev`
  ```

  Now:

  ```console
  $ prek run
  error: Failed to parse `.pre-commit-config.yaml`
  caused by: error: line 2 column 5: missing field `rev` at line 2, column 5
  --> <input>:2:5
    |
  1 | repos:
  2 |   - repo: https://github.com/crate-ci/typos
    |     ^ missing field `rev` at line 2, column 5
  3 |     hooks:
  4 |       - id: typos
    |
  ```

- **`prek util` subcommands**

  We added a new `prek util` top-level command for miscellaneous utilities that don't fit into other categories. The first two utilities are:

  - `prek util identify`: shows the identification tags of files that prek uses for file filtering, which can be useful for debugging and writing `types/types_or/exclude_types` filters.
  - `prek util yaml-to-toml`: converts `.pre-commit-config.yaml` to `prek.toml`.

  We also moved `prek init-template-dir` under `prek util` for better organization. The old `prek init-template-dir` command is still available (hidden) as an alias for backward compatibility.

##### Enhancements

- Add `prek util identify` subcommand ([#&#8203;1554](j178/prek#1554))
