mdast-util-to-nlcst

mdast utility to transform to nlcst.

Note: You probably want to use remark-retext.

Install

npm:

npm install mdast-util-to-nlcst

Use

var toNlcst = require('mdast-util-to-nlcst')
var inspect = require('unist-util-inspect')
var English = require('parse-english')
var remark = require('remark')
var vfile = require('vfile')

var file = vfile('Some *foo*sball.')
var mdast = remark().parse(file)

var nlcst = toNlcst(mdast, file, English)

console.log(inspect(nlcst))

Yields:

RootNode[1] (1:1-1:17, 0-16)
└─0 ParagraphNode[1] (1:1-1:17, 0-16)
    └─0 SentenceNode[4] (1:1-1:17, 0-16)
        ├─0 WordNode[1] (1:1-1:5, 0-4)
        │   └─0 TextNode "Some" (1:1-1:5, 0-4)
        ├─1 WhiteSpaceNode " " (1:5-1:6, 4-5)
        ├─2 WordNode[2] (1:7-1:16, 6-15)
        │   ├─0 TextNode "foo" (1:7-1:10, 6-9)
        │   └─1 TextNode "sball" (1:11-1:16, 10-15)
        └─3 PunctuationNode "." (1:16-1:17, 15-16)

API

toNlcst(tree, file, Parser[, options])

Transform a tree in mdast, with a corresponding virtual file, into nlcst.

Parameters

node

Tree in mdast with positional information (MdastNode).

file

Virtual file (VFile).

parser

nlcst parser (Function). For example, parse-english, parse-dutch, or parse-latin.

options.ignore

List of types to ignore (Array.<string>).

'table', 'tableRow', and 'tableCell' are always ignored.

List of types to mark as source (Array.<string>).

'inlineCode' is always marked as source.

Returns

NlcstNode.

Examples

ignore

Say we have the following file example.md:

A paragraph.

> A paragraph in a block quote.

…and if we now transform with ignore: ['blockquote'], we get:

RootNode[2] (1:1-3:1, 0-14)
├─0 ParagraphNode[1] (1:1-1:13, 0-12)
│   └─0 SentenceNode[4] (1:1-1:13, 0-12)
│       ├─0 WordNode[1] (1:1-1:2, 0-1)
│       │   └─0 TextNode "A" (1:1-1:2, 0-1)
│       ├─1 WhiteSpaceNode " " (1:2-1:3, 1-2)
│       ├─2 WordNode[1] (1:3-1:12, 2-11)
│       │   └─0 TextNode "paragraph" (1:3-1:12, 2-11)
│       └─3 PunctuationNode "." (1:12-1:13, 11-12)
└─1 WhiteSpaceNode "\n\n" (1:13-3:1, 12-14)

source

Say we have the following file example.md:

A paragraph.

> A paragraph in a block quote.

…and if we now transform with source: ['blockquote'], we get:

RootNode[3] (1:1-3:32, 0-45)
├─0 ParagraphNode[1] (1:1-1:13, 0-12)
│   └─0 SentenceNode[4] (1:1-1:13, 0-12)
│       ├─0 WordNode[1] (1:1-1:2, 0-1)
│       │   └─0 TextNode "A" (1:1-1:2, 0-1)
│       ├─1 WhiteSpaceNode " " (1:2-1:3, 1-2)
│       ├─2 WordNode[1] (1:3-1:12, 2-11)
│       │   └─0 TextNode "paragraph" (1:3-1:12, 2-11)
│       └─3 PunctuationNode "." (1:12-1:13, 11-12)
├─1 WhiteSpaceNode "\n\n" (1:13-3:1, 12-14)
└─2 ParagraphNode[1] (3:1-3:32, 14-45)
    └─0 SentenceNode[1] (3:1-3:32, 14-45)
        └─0 SourceNode "> A paragraph in a block quote." (3:1-3:32, 14-45)
