## What is this?

This package exposes comparators for vfile files and messages.

## When should I use this?

You can use this right before a reporter is used to give humans a coherent
report.

## Install

This package is [ESM only][esm].
In Node.js (version 16+), install with [npm][]:

```sh
npm install vfile-sort
```

In Deno with [`esm.sh`][esmsh]:

```js
import {sort} from 'https://esm.sh/vfile-sort@4'
```

In browsers with [`esm.sh`][esmsh]:

```html
<script type="module">
  import {sort} from 'https://esm.sh/vfile-sort@4?bundle'
</script>
```

## Use

```js
import {VFile} from 'vfile'
import {VFileMessage} from 'vfile-message'
import {compareFile, compareMessage} from 'vfile-sort'

console.log(
  [
    new VFileMessage('Error!', {place: {line: 3, column: 1}}),
    new VFileMessage('Another!', {place: {line: 2, column: 2}})
  ]
    .toSorted(compareMessage)
    .map(String)
) //=> ['2:2: Another!', '3:1: Error!']

console.log(
  [
    new VFile(new URL(import.meta.url)),
    new VFile(new URL('.', import.meta.url))
  ]
    .toSorted(compareFile)
    .map((d) => d.path)
) //=> ['/Users/tilde/Projects/oss/vfile-sort/', '/Users/tilde/Projects/oss/vfile-sort/example.js']
```

## API

This package exports the identifiers [`compareFile`][api-compare-file] and
[`compareMessage`][api-compare-message].
There is no default export.

### `compareFile(a, b)`

Compare files (since: `4.0.0`).

###### Parameters

*   `a` ([`VFile`][vfile])
    — file
*   `b` ([`VFile`][vfile])
    — other file

###### Returns

Order (`number`).

### `compareMessage(a, b)`

Compare messages (since: `4.0.0`).

###### Algorithm

It first sorts by line/column: earlier messages come first.
When two messages occurr at the same place, sorts fatal error before
warnings, before info messages.
Finally, it sorts using `localeCompare` on `source`, `ruleId`, or finally
`reason`.

###### Parameters

*   `a` ([`VFile`][vfile])
    — message
*   `b` ([`VFile`][vfile])
    — other message

###### Returns

Order (`number`).

## Types

This package is fully typed with [TypeScript][].
It exports no additional types.

## Compatibility

Projects maintained by the unified collective are compatible with maintained
versions of Node.js.

When we cut a new major release, we drop support for unmaintained versions of
Node.
This means we try to keep the current release line, `vfile-sort@^4`,
compatible with Node.js 16.
