vfile-sort
vfile utility to sort files or messages.
Contents
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. In Node.js (version 16+), install with npm:
npm install vfile-sort
In Deno with esm.sh:
import {sort} from 'https://esm.sh/vfile-sort@4'
In browsers with esm.sh:
<script type="module">
import {sort} from 'https://esm.sh/vfile-sort@4?bundle'
</script>
Use
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 and compareMessage. There is no default export.
compareFile(a, b)
Compare files (since: 4.0.0).
Parameters
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
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.
