ESLint plugin to enforce and auto-fix pnpm catalogs.

This plugin consist with two set of rules that applies to `package.json` and `pnpm-workspace.yaml` respectively.

- [`json-` rules](./src/rules/json) applies to `package.json` and requires [`jsonc-eslint-parser`](https://github.com/ota-meshi/jsonc-eslint-parser) to be used as parser.
- [`yaml-` rules](./src/rules/yaml) applies to `pnpm-workspace.yaml` and requires [`yaml-eslint-parser`](https://github.com/ota-meshi/yaml-eslint-parser) to be used as parser.
  - YAML support is still experimental as it might have race conditions with other plugins.

## Setup

```bash
pnpm add -D eslint-plugin-pnpm
```

// eslint.config.mjs
import { configs } from 'eslint-plugin-pnpm'

  ...configs.json,
  ...configs.yaml,
]
```
