Fix FilePattern schema to accept plain strings by Copilot · Pull Request #1564 · j178/prek

Copilot · 2026-02-04T21:07:09Z

The JSON schema for FilePattern required object notation ({ regex: "..." } or { glob: "..." }), but the deserializer accepts plain strings as regex patterns. This caused existing pre-commit configs to fail validation:

exclude: foo  # Failed schema validation but deserializes correctly

Changes

Updated FilePattern::json_schema() to accept plain strings as the first oneOf variant
Removed the non-existent { regex: "..." } object format
Regenerated prek.schema.json

The schema now matches deserialization behavior, accepting:

Plain strings (treated as regex): exclude: foo
Glob objects: exclude: { glob: "*.py" }
Glob arrays: exclude: { glob: ["*.py", "*.pyc"] }

<issue_title>Schema bug: FilePattern doesn't include strings so validation of pre-commit compatible config files fails</issue_title>
<issue_description>### Summary

Existing pre-commit config files that use file patterns like exclude don't pass yaml schema validation in prek.

This is the definition of global file exclude patterns: use FilePattern.

    "exclude": {
      "description": "Global file exclude pattern.",
      "anyOf": [
        {
          "$ref": "#/definitions/FilePattern"
        },
        {
          "type": "null"
        }
      ]
    },

FilePattern is:

    "FilePattern": {
      "description": "A file pattern, either a regex or glob pattern(s).",
      "type": "object",
      "oneOf": [
        {
          "type": "object",
          "properties": {
            "regex": {
              "description": "A regular expression pattern.",
              "type": "string"
            }
          },
          "required": [
            "regex"
          ]
        },
        {
          "type": "object",
          "properties": {
            "glob": {
              "oneOf": [
                {
                  "description": "A glob pattern.",
                  "type": "string"
                },
                {
                  "description": "A list of glob patterns.",
                  "type": "array",
                  "items": {
                    "type": "string"
                  }
                }
              ]
            }
          },
          "required": [
            "glob"
          ]
        }
      ]
    },

Note that it doesn't include being a plain string at the top level of FilePattern. i.e.:

---
exclude: foo

This means that existing pre-commit config files that use exclusions don't pass validation with the provided JSON schema.

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 ([#2041](j178/prek#2041)) - Add project auto-update cooldown config ([#2044](j178/prek#2044)) - Support `language: dart` ([#1146](j178/prek#1146)) ##### Bug fixes - Pass commit message file to workspace hooks ([#2043](j178/prek#2043)) - Preserve non-UTF8 filenames from git ([#2023](j178/prek#2023)) - ruby: put resolved Ruby's bin dir on `$PATH` for `gem` invocations ([#2021](j178/prek#2021)) ##### Documentation - Update docs with the new logo and icon ([#2025](j178/prek#2025)) - Point schema docs to SchemaStore ([#2039](j178/prek#2039)) ##### Contributors - [@j178](https://github.com/j178) - [@xiaoyanli-lyft](https://github.com/xiaoyanli-lyft) - [@Lutra-Fs](https://github.com/Lutra-Fs) ### [`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 ([#1983](j178/prek#1983)) - Add `auto-update --exit-code` to exit with non-zero on updates ([#2002](j178/prek#2002)) - Add `auto-update --include-tag <pattern>`/`--exclude-tag <pattern>` to filter tags ([#1984](j178/prek#1984)) - Adds an explicit `shell` hook option for entries that should run as shell source ([#2004](j178/prek#2004)) - Make `--hook-dir` optional for hook-impl ([#1989](j178/prek#1989)) - Skip shim warning when `--script-version` is missing ([#1990](j178/prek#1990)) ##### Bug fixes - Install Ruby executable in gem bin ([#2017](j178/prek#2017)) - Use dedicated Android npm package ([#1982](j178/prek#1982)) - Use stable repo keys without breaking cached clones ([#1995](j178/prek#1995)) ##### Documentation - Explain prek name ([#1980](j178/prek#1980)) - Clarify `pass_filenames` concurrency docs ([#1999](j178/prek#1999)) - Reorganize documentation references ([#2005](j178/prek#2005)) - Clarify hook author manifest env docs ([#1991](j178/prek#1991)) - docs: add Sentry to users list ([#1981](j178/prek#1981)) ##### Contributors - [@j178](https://github.com/j178) ### [`v0.3.10`](https://github.com/j178/prek/blob/HEAD/CHANGELOG.md#0310) [Compare Source](j178/prek@v0.3.9...v0.3.10) Released on 2026-04-21. ##### Enhancements - Disallow rev for non-remote repos in schema ([#1964](j178/prek#1964)) - Hide up-to-date output in non-verbose mode ([#1942](j178/prek#1942)) - Improve merge conflict marker detection ([#1937](j178/prek#1937)) - Keep finished hooks visible ([#1967](j178/prek#1967)) - Preserve frozen comment spacing in auto-update ([#1945](j178/prek#1945)) - Reimplement `@j178/prek` npm package ([#1973](j178/prek#1973)) ##### Bug fixes - Prefer stable Rust toolchains ([#1974](j178/prek#1974)) ##### Documentation - Add `SKILL.md` for prek ([#1950](j178/prek#1950)) - Document `gh skill install j178/prek prek` to install prek skill for agents ([#1951](j178/prek#1951)) - Improve compatibility and migration docs ([#1940](j178/prek#1940)) ##### Other changes - Sync latest identify tags ([#1947](j178/prek#1947)) ##### Contributors - [@github-actions](https://github.com/github-actions) - [@renovate](https://github.com/renovate) - [@j178](https://github.com/j178) ### [`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 ``` ##### Enhancements -

**`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 ([#1554](j178/prek#1554)) - Add `prek util yaml-to-toml` to convert `.pre-commit-config.yaml` to `prek.toml` ([#1584](j178/prek#1584)) - Detect install source for actionable upgrade hints ([#1540](j178/prek#1540)) - Detect prek installed by the standalone installer ([#1545](j178/prek#1545)) - Implement `serialize_yaml_scalar` using `serde-saphyr` ([#1534](j178/prek#1534)) - Improve max cli arguments length calculation ([#1518](j178/prek#1518)) - Move `identify` and `init-template-dir` under the `prek util` top-level command ([#1574](j178/prek#1574)) - Replace serde-yaml with serde-saphyr (again) ([#1520](j178/prek#1520)) - Show precise location for config parsing error ([#1530](j178/prek#1530)) - Support `Julia` language ([#1519](j178/prek#1519)) - Support `prek.toml` ([#1271](j178/prek#1271)) - Added `PREK_QUIET` environment variable support ([#1513](j178/prek#1513)) - Remove upper bound constraint of uv version ([#1588](j178/prek#1588)) ##### Bug fixes - Do not make the child a session leader ([#1586](j178/prek#1586)) - Fix FilePattern schema to accept plain strings ([#1564](j178/prek#1564)) - Use semver fallback sort when tag timestamps are equal ([#1579](j178/prek#1579)) ##### Documentation - Add `OpenClaw` to the list of users ([#1517](j178/prek#1517)) - Add `cachix/devenv`, `apache/lucene`, `copper-project/copper-rs` as projects using prek ([#1531](j178/prek#1531), [#1514](j178/prek#1514), [#1569](j178/prek#1569)) - Add document about authoring remote hooks ([#1571](j178/prek#1571)) - Add `llms.txt` generation for LLM-friendly documentation ([#1553](j178/prek#1553)) - Document using `--refresh` to pick up `.prekignore` changes ([#1575](j178/prek#1575)) - Fix PowerShell completion instruction syntax ([#1568](j178/prek#1568)) - Update quick start to use `prek.toml` ([#1576](j178/prek#1576)) ##### Other changes - Include `prek.toml` in run hint for config filename ([#1578](j178/prek#1578)) ##### Contributors - [@fatelei](https://github.com/fatelei) - [@domenkozar](https://github.com/domenkozar) - [@makeecat](https://github.com/makeecat) - [@fllesser](https://github.com/fllesser) - [@j178](https://github.com/j178) - [@copilot-swe-agent](https://github.com/copilot-swe-agent) - [@oopscompiled](https://github.com/oopscompiled) - [@rmuir](https://github.com/rmuir) - [@shaanmajid](https://github.com/shaanmajid) </details> --- ### Configuration 📅 **Schedule**: (UTC) - Branch creation - At any time (no schedule defined) - Automerge - At any time (no schedule defined) 🚦 **Automerge**: Disabled by config.
