## What is this?
This is a tiny, but useful, package that pretty prints any [unist][unist] [*tree*][tree].
## When should I use this?
This utility pretty prints the tree in a format custom made for unist trees. This is useful for spotting bugs, as well
as getting an idea of whats going on in the tree. Both trees and node lists can be printed.
## Install
This package is [ESM only][esm].
In Node.js (version 18+) with [yarn][yarn]:
```sh
yarn add @flex-development/unist-util-inspect
```
See Git - Protocols | Yarn
for details regarding installing from Git.
In Deno with [`esm.sh`][esmsh]:
```ts
import { inspect } from 'https://esm.sh/@flex-development/unist-util-inspect'
```
In browsers with [`esm.sh`][esmsh]:
```html
import { inspect } from 'https://esm.sh/@flex-development/unist-util-inspect'
```
## Use
Suppose we have the file [`dbl-linear.ts`](examples/dbl-linear.ts), and the following module, `example.ts`:
```ts
import type * as docast from '@flex-development/docast'
import { fromDocs } from '@flex-development/docast-util-from-docs'
import { inspect } from '@flex-development/unist-util-inspect'
import { read } from 'to-vfile'
import type { VFile } from 'vfile'
const file: VFile = await read('dbl-linear.ts')
const tree: docast.Root = fromDocs(file)
console.log(inspect(tree))
```
...running `node --loader=./loader.mjs example.ts` yields:
```sh

#### Parameters
- `tree` (`unknown`) — tree to inspect
- `options` ([`Options`](#options) | `null` | `undefined`) — configuration options
#### Returns
(`string`) Pretty printed `tree`.
### `inspectColor(tree[, options])`
Inspect a tree, with color.
Otherwise the same as [`inspect`](#inspecttree-options).
### `inspectNoColor(tree[, options])`
Inspect a tree, without color.
Otherwise the same as [`inspect`](#inspecttree-options).
### `Options`
