unist-util-inspect

What is unist-util-inspect?

The `unist-util-inspect` package is a utility for inspecting and visualizing the structure of Unist syntax trees. It provides a way to convert these trees into a human-readable string format, which is useful for debugging and understanding the tree structure.

What are unist-util-inspect's main functionalities?

Inspecting a Unist Tree

This feature allows you to inspect a Unist tree by converting it into a human-readable string format. The code sample demonstrates how to use the `inspect` function to visualize a simple Unist tree.

const inspect = require('unist-util-inspect');
const tree = {
  type: 'root',
  children: [
    { type: 'paragraph', children: [{ type: 'text', value: 'Hello, world!' }] }
  ]
};
console.log(inspect(tree));

Other packages similar to unist-util-inspect

unist-util-visit

The `unist-util-visit` package is used for tree traversal in Unist syntax trees. It allows you to visit nodes in a tree and perform operations on them. Unlike `unist-util-inspect`, which focuses on visualizing the tree, `unist-util-visit` is more about manipulating and traversing the tree.

unist-builder

The `unist-builder` package provides a way to create Unist syntax trees programmatically. It is useful for constructing trees from scratch, whereas `unist-util-inspect` is used for visualizing existing trees.

unist-util-map

The `unist-util-map` package allows you to transform Unist trees by applying a function to each node. This is different from `unist-util-inspect`, which is used for visualizing the tree structure rather than transforming it.

unist utility to inspect nodes.

Install

This package is ESM only: Node 12+ is needed to use it and it must be imported instead of required.

npm:

npm install unist-util-inspect

Use

var u = require('unist-builder')
var inspect = require('unist-util-inspect')

var tree = u('root', [
  u('literal', '1'),
  u('parent', [
    u('void', {id: 'a'}),
    u('literal', '2'),
    u('node', {id: 'b'}, [])
  ])
])

console.log(inspect(tree))

Yields:

root[2]
├─0 literal "1"
└─1 parent[3]
    ├─0 void
    │     id: "a"
    ├─1 literal "2"
    └─2 node[0]
          id: "b"

API

This package exports the following identifiers: inspect, inspectColor, and inspectNoColor. There is no default export.

inspect(node[, options])

Inspect the given node. By default, colors are added in Node, and not in other places. See below on how to change that.

options.showPositions

Whether to include positional information (boolean, default: true).

Returns

string — String representing node.

inspectColor(node[, options])

Inspect, with ANSI color sequences (default in Node).

inspectNoColor(node[, options])

Inspect, but without ANSI color sequences (default in browser).
