You can run `pretty-quick` as a pre-commit hook using [`husky`](https://github.com/typicode/husky).

## CLI Flags

### `--staged` (only git)

Pre-commit mode. Under this flag only staged files will be formatted, and they will be re-staged after formatting.

Partially staged files will not be re-staged after formatting and pretty-quick will exit with a non-zero exit code. The intent is to abort the git commit and allow the user to amend their selective staging to include formatting fixes.

### `--no-restage` (only git)

Use with the `--staged` flag to skip re-staging files after formatting.

### `--branch`

When not in `staged` pre-commit mode, use this flag to compare changes with the specified branch. Defaults to `master` (git) / `default` (hg) branch.

### `--pattern`

Filters the files for the given [minimatch](https://github.com/isaacs/minimatch) pattern.  
For example `pretty-quick --pattern "**/*.*(js|jsx)"` or `pretty-quick --pattern "**/*.js" --pattern "**/*.jsx"`

### `--verbose`

Outputs the name of each file right before it is proccessed. This can be useful if Prettier throws an error and you can't identify which file is causing the problem.

### `--bail`

Prevent `git commit` if any files are fixed.

### `--check`

Check that files are correctly formatted, but don't format them. This is useful on CI to verify that all changed files in the current branch were correctly formatted.

### `--no-resolve-config`

Do not resolve prettier config when determining which files to format, just use standard set of supported file types & extensions prettier supports. This may be useful if you do not need any customization and see performance issues.

By default, pretty-quick will check your prettier configuration file for any overrides you define to support formatting of additional file extensions.

Example `.prettierrc` file to support formatting files with `.cmp` or `.page` extensions as html.

```
{
    "printWidth": 120,
    "bracketSpacing": false,
    "overrides": [
        {
            "files": "*.{cmp,page}",
            "options": {"parser": "html"}
        }
    ],
}
```

<!-- Undocumented = Unsupported :D

### `--config`

Path to a `.prettierrc` file.

### `--since`

A SCM revision such as a git commit hash or ref.

For example `pretty-quick --since HEAD` will format only staged files.

-->

### `--ignore-path`

Check an alternative file for ignoring files with the same format as [`.prettierignore`](https://prettier.io/docs/en/ignore#ignoring-files).
For example `pretty-quick --ignore-path .gitignore`

## Configuration and Ignore Files

`pretty-quick` will respect your [`.prettierrc`](https://prettier.io/docs/en/configuration), [`.prettierignore`](https://prettier.io/docs/en/ignore#ignoring-files), and [`.editorconfig`](http://editorconfig.org/) files if you don't use `--ignore-path` . Configuration files will be found by searching up the file system. `.prettierignore` files are only found from the repository root and the working directory that the command was executed from.
