unist utility to pretty print the positional info of a node.

Contents

What is this?

This package is a utility that takes any unist (whether mdast, hast, etc) node, position, or point, and serializes its positional info.

When should I use this?

This utility is useful to display where something occurred in the original document, in one standard way, for humans. For example, when throwing errors or warning messages about something.

Install

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

npm install unist-util-stringify-position

In Deno with esm.sh:

import {stringifyPosition} from 'https://esm.sh/unist-util-stringify-position@4'

In browsers with esm.sh:

<script type="module">
  import {stringifyPosition} from 'https://esm.sh/unist-util-stringify-position@4?bundle'
</script>

Use

import {stringifyPosition} from 'unist-util-stringify-position'

stringifyPosition({line: 2, column: 3}) // => '2:3' (point)
stringifyPosition({start: {line: 2}, end: {line: 3}}) // => '2:1-3:1' (position)
stringifyPosition({
  type: 'text',
  value: '!',
  position: {
    start: {line: 5, column: 11},
    end: {line: 5, column: 12}
  }
}) // => '5:11-5:12' (node)

API

This package exports the identifier stringifyPosition. There is no default export.

stringifyPosition(node|position|point)

Serialize the positional info of a point, position (start and end points), or node.

Parameters
  • node (Node) — node whose position fields to serialize
  • position (Position) — position whose start and end points to serialize
  • point (Point) — point whose line and column fields to serialize
Returns

Pretty printed positional info of a node (string).

In the format of a range ls:cs-le:ce (when given node or position) or a point l:c (when given point), where l stands for line, c for column, s for start, and e for end. An empty string ('') is returned if the given value is neither node, position, nor point.

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, unist-util-stringify-position@^4, compatible with Node.js 16.

Security

This project is safe.
