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

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

API

inspect(node)

By default, color support is enabled in Node.js and turned off anywhere else. See below on how to change that.

Parameters

• node (Node).

Returns

string — String representing node.

inspect.<style>[.<style>…](node)

Where <style> is either color or noColor.

To explicitly add or remove ANSI sequences, use either inspect.color(node) or inspect.noColor(node).
