Merge multiple ESLint processors to behave like one

## Install

```bash
npm i eslint-merge-processors
```

```js
import { mergeProcessors } from 'eslint-merge-processors'

const processor = mergeProcessors([
  processorA,
  processorB,
  // ...
])
```

## Examples

### Markdown

Lint `.md` files with `eslint-plugin-markdown`.

By default, `eslint-plugin-markdown`'s processor will create a virtual file for each code snippet in the markdown file, **but not the original `.md` file itself**. This means the original `.md` file will not be linted.

With this package, along with the `processorPassThrough` processor, you can now fix that:

```ts
import {
  mergeProcessors,
  processorPassThrough
} from 'eslint-merge-processors'
import markdown from 'eslint-plugin-markdown'

// ESlint Flat config
export default [
  {
    files: ['**/*.md'],
    plugins: {
      markdown
    },
    processor: mergeProcessors([
      // This allow the original `.md` file to be linted
      processorPassThrough,
      // The markdown processor
      markdown.processors.markdown,
      // other processors if needed
    ])
  }
]
```
