import { const unified: Processor<undefined, undefined, undefined, undefined, undefined>
Create a new processor.
@example  This example shows how a new processor can be created (from `remark`) and linked
  to **stdin**(4) and **stdout**(4).

  ```js
  import process from 'node:process'
  import concatStream from 'concat-stream'
  import {remark} from 'remark'

  process.stdin.pipe(
    concatStream(function (buf) {
      process.stdout.write(String(remark().processSync(buf)))
    })
  )
  ```@returns  New *unfrozen* processor (`processor`).

  This processor is configured to work the same as its ancestor.
  When the descendant processor is configured in the future it does not
  affect the ancestral processor.unified, type type Parser<Tree extends import("unist").Node = Node> = (document: string, file: VFile) => Tree
A **parser** handles the parsing of text to a syntax tree.

It is used in the parse phase and is called with a `string` and

{@linkcode 
VFile
}
 of the document to parse.
It must return the syntax tree representation of the given file
(
{@linkcode 
Node
}
).Parser } from "unified";
 
function function remParse(): voidremParse() {
  const const self: anyself = this;
 
  const self: anyself.parser = function (local function) parser(doc: string, file: unknown): anyparser as type Parser<Tree extends import("unist").Node = Node> = (document: string, file: VFile) => Tree

  import concatStream from 'concat-stream'

    Processor<undefined, undefined, undefined, undefined, undefined>.use<[], undefined, undefined>(plugin: Plugin<[], undefined, undefined>, ...parameters: [] | [boolean]): Processor<undefined, undefined, undefined, undefined, undefined> (+2 overloads)
Configure the processor to use a plugin, a list of usable values, or a
preset.

If the processor is already using a plugin, the previous plugin
configuration is changed based on the options that are passed in.
In other words, the plugin is not added a second time.

> **Note**: `use` cannot be called on *frozen* processors.
> Call the processor first to create a new unfrozen processor.
@example  There are many ways to pass plugins to `.use()`.
  This example gives an overview:

  ```js
  import {unified} from 'unified'

  unified()
    // Plugin with options:
    .use(pluginA, {x: true, y: true})
    // Passing the same plugin again merges configuration (to `{x: true, y: false, z: true}`):
    .use(pluginA, {y: false, z: true})
    // Plugins:
    .use([pluginB, pluginC])
    // Two plugins, the second with options:
    .use([pluginD, [pluginE, {}]])
    // Preset with plugins and settings:
    .use({plugins: [pluginF, [pluginG, {}]], settings: {position: false}})
    // Settings only:
    .use({settings: {position: false}})
  ```@template{Array<unknown>} [Parameters=[]]@template{Node | string | undefined} [Input=undefined]@template[Output=Input]@overload@overload@overload@paramvalue Usable value.@paramparameters Parameters, when a plugin is given as a usable value.@returnsCurrent processor.use(function remParse(): voidremParse).
