Using this option removes all guarantees of + portability to other yaml implementations. + Implies `--allow-multiple-documents`. + +#### `debug-statements` +Check for debugger imports and py37+ `breakpoint()` calls in python source. + +#### `destroyed-symlinks` +Detects symlinks which are changed to regular files with a content of a path +which that symlink was pointing to. +This usually happens on Windows when a user clones a repository that has +symlinks but they do not have the permission to create symlinks. + +#### `detect-aws-credentials` +Checks for the existence of AWS secrets that you have set up with the AWS CLI. +The following arguments are available: +- `--credentials-file CREDENTIALS_FILE` - additional AWS CLI style + configuration file in a non-standard location to fetch configured + credentials from. Can be repeated multiple times. +- `--allow-missing-credentials` - Allow hook to pass when no credentials are detected. + +#### `detect-private-key` +Checks for the existence of private keys. + +#### `double-quote-string-fixer` +This hook replaces double quoted strings with single quoted strings. + +#### `end-of-file-fixer` +Makes sure files end in a newline and only a newline. + +#### `fix-byte-order-marker` +removes UTF-8 byte order marker + +#### `fix-encoding-pragma` +Add `# -*- coding: utf-8 -*-` to the top of python files. + - To remove the coding pragma pass `--remove` (useful in a python3-only codebase) + +#### `file-contents-sorter` +Sort the lines in specified files (defaults to alphabetical). +You must provide list of target files as input to it. +Note that this hook WILL remove blank lines and does NOT respect any comments. + +#### `forbid-new-submodules` +Prevent addition of new git submodules. + +#### `mixed-line-ending` +Replaces or checks mixed line ending. + - `--fix={auto,crlf,lf,no}` + - `auto` - Replaces automatically the most frequent line ending. This is the default argument. + - `crlf`, `lf` - Forces to replace line ending by respectively CRLF and LF. + - This option isn't compatible with git setup check-in LF check-out CRLF as git smudge this later than the hook is invoked. + - `no` - Checks if there is any mixed line ending without modifying any file. + +#### `name-tests-test` +Assert that files in tests/ end in `_test.py`. + - Use `args: ['--django']` to match `test*.py` instead. + +#### `no-commit-to-branch` +Protect specific branches from direct checkins. + - Use `args: [--branch, staging, --branch, master]` to set the branch. + Both `master` and `main` are protected by default if no branch argument is set. + - `-b` / `--branch` may be specified multiple times to protect multiple + branches. + - `-p` / `--pattern` can be used to protect branches that match a supplied regex + (e.g. `--pattern, release/.*`). May be specified multiple times. + +Note that `no-commit-to-branch` is configured by default to [`always_run`](https://pre-commit.com/#config-always_run). +As a result, it will ignore any setting of [`files`](https://pre-commit.com/#config-files), +[`exclude`](https://pre-commit.com/#config-exclude), [`types`](https://pre-commit.com/#config-types) +or [`exclude_types`](https://pre-commit.com/#config-exclude_types). +Set [`always_run: false`](https://pre-commit.com/#config-always_run) to allow this hook to be skipped according to these +file filters. Caveat: In this configuration, empty commits (`git commit --allow-empty`) would always be allowed by this hook. + +#### `pretty-format-json` +Checks that all your JSON files are pretty. "Pretty" +here means that keys are sorted and indented. You can configure this with +the following commandline options: + - `--autofix` - automatically format json files + - `--indent ...` - Control the indentation (either a number for a number of spaces or a string of whitespace). Defaults to 2 spaces. + - `--no-ensure-ascii` preserve unicode characters instead of converting to escape sequences + - `--no-sort-keys` - when autofixing, retain the original key ordering (instead of sorting the keys) + - `--top-keys comma,separated,keys` - Keys to keep at the top of mappings. + +#### `requirements-txt-fixer` +Sorts entries in requirements.txt and removes incorrect entry for `pkg-resources==0.0.0` + +#### `sort-simple-yaml` +Sorts simple YAML files which consist only of top-level +keys, preserving comments and blocks. + +Note that `sort-simple-yaml` by default matches no `files` as it enforces a +very specific format. You must opt in to this by setting [`files`](https://pre-commit.com/#config-files), for example: + +```yaml + - id: sort-simple-yaml + files: ^config/simple/ +``` + + +#### `trailing-whitespace` +Trims trailing whitespace. + - To preserve Markdown [hard linebreaks](https://github.github.com/gfm/#hard-line-break) + use `args: [--markdown-linebreak-ext=md]` (or other extensions used + by your markdownfiles). If for some reason you want to treat all files + as markdown, use `--markdown-linebreak-ext=*`. + - By default, this hook trims all whitespace from the ends of lines. + To specify a custom set of characters to trim instead, use `args: [--chars,"<chars to trim>"]`. + +### Deprecated / replaced hooks + +- `check-byte-order-marker`: instead use fix-byte-order-marker + +### As a standalone package + +If you'd like to use these hooks, they're also available as a standalone package. + +Simply `pip install pre-commit-hooks` |
