## The packages

- [prettier](https://www.npmjs.com/package/prettier)
- [prettier-plugin-nginx](https://www.npmjs.com/package/prettier-plugin-nginx)
- [@prettier/plugin-ruby](https://www.npmjs.com/package/@prettier/plugin-ruby)
- [prettier-plugin-toml](https://www.npmjs.com/package/prettier-plugin-toml)
- [@prettier/plugin-xml](https://www.npmjs.com/package/@prettier/plugin-xml)
- [prettier-plugin-sh](https://www.npmjs.com/package/prettier-plugin-sh)

## Installation

1. `npm install -D -E prettier@3.3.1 prettier-plugin-nginx@1.0.3 @prettier/plugin-ruby@4.0.4 prettier-plugin-toml@2.0.1 @prettier/plugin-xml@3.4.1 prettier-plugin-sh@0.14.0` or probably just `pnpm install -D` if it's not your project.
1. If they don't exist already `echo "{}" > .prettierrc && touch .prettierignore`
1. `pnpm exec prettier . --write` or `pnpm exec prettier . --check`

## Configuration

I do with `.editorconfig` what I can, but for example this site's `.prettierrc` looks like:

```json
{
  "plugins": ["@prettier/plugin-xml"],
  "overrides": [{ "files": ".prettierrc", "options": { "parser": "json" } }]
}
```

at the time of writing. It's directly from documentation excluding the plugin name, but I will want it everywhere.

## `.pre-commit-config.yaml`

This is the file that controls [`pre-commit`]s behaviour.

### Offline

I accidentally wrote this while updating this page to reflect me using prettier outside of [`pre-commit`] too nowadays. This has the advantage that the same local environment gets reused and dependencies are managed centrally, but assumes everyone uses pnpm, won't work in [`pre-commit` ci] and may have other issues I am not thinking of as a not-coder myself.

[`pre-commit`]: https://pre-commit.com
[`pre-commit` ci]: https://pre-commit.ci

```yaml
ci:
  skip: [pnpm-prettier]
repos:
  - repo: local
    hooks:
      - id: pnpm-prettier
        name: prettier
        entry: pnpm exec prettier --cache --ignore-unknown --write
        language: system
        # Better handled by pretty-format-json from pre-commit-hooks.
        # Remember to have *.json in .prettierignore!
        exclude_types: [json]
```

### Online

```yaml

  #- repo: https://github.com/pre-commit/mirrors-prettier
  - repo: https://github.com/rbubley/mirrors-prettier
    rev: "v3.3.1"
    hooks:
      - id: prettier
        # Better handled by pretty-format-json from pre-commit-hooks.
        # Remember to have *.json in .prettierignore!
        exclude_types: [json]
        additional_dependencies: [
            # https://aminda.eu/n/prettier
            "prettier@3.3.1",
            "prettier-plugin-nginx@1.0.3",
