nlcst utility to classify ASCII emoticons as EmoticonNodes.

Contents

What is this?

This utility searches for emoticons made with punctuation marks and symbols, and turns them into separate nodes.

When should I use this?

This package is a tiny utility that helps when dealing with plain-text emoticons in natural language. The plugin retext-emoji wraps this utility and others at a higher-level (easier) abstraction.

Install

This package is ESM only. In Node.js (version 16+), install with npm:

npm install nlcst-emoticon-modifier

In Deno with esm.sh:

import {emoticonModifier} from 'https://esm.sh/nlcst-emoticon-modifier@3'

In browsers with esm.sh:

<script type="module">
  import {emoticonModifier} from 'https://esm.sh/nlcst-emoticon-modifier@3?bundle'
</script>

Use

import {emoticonModifier} from 'nlcst-emoticon-modifier'
import {ParseEnglish} from 'parse-english'
import {inspect} from 'unist-util-inspect'

const parser = new ParseEnglish()
parser.tokenizeSentencePlugins.unshift(emoticonModifier)

const sentence = parser.parse('This makes me feel :).').children[0].children[0]

console.log(inspect(sentence))

Yields:

SentenceNode[10] (1:1-1:23, 0-22)
├─0 WordNode[1] (1:1-1:5, 0-4)
│   └─0 TextNode "This" (1:1-1:5, 0-4)
├─1 WhiteSpaceNode " " (1:5-1:6, 4-5)
├─2 WordNode[1] (1:6-1:11, 5-10)
│   └─0 TextNode "makes" (1:6-1:11, 5-10)
├─3 WhiteSpaceNode " " (1:11-1:12, 10-11)
├─4 WordNode[1] (1:12-1:14, 11-13)
│   └─0 TextNode "me" (1:12-1:14, 11-13)
├─5 WhiteSpaceNode " " (1:14-1:15, 13-14)
├─6 WordNode[1] (1:15-1:19, 14-18)
│   └─0 TextNode "feel" (1:15-1:19, 14-18)
├─7 WhiteSpaceNode " " (1:19-1:20, 18-19)
├─8 EmoticonNode ":)" (1:20-1:22, 19-21)
└─9 PunctuationNode "." (1:22-1:23, 21-22)

API

This package exports the identifier emoticonModifier. There is no default export.

emoticonModifier(node)

Merge emoticons in a SentenceNode into EmoticonNodes.

Parameters
Returns

Nothing (undefined).

Emoticon

Emoticon node (TypeScript type).

Type
import type {Data, Literal} from 'nlcst'

interface Emoticon extends Literal {
  type: 'EmoticonNode'
  data?: EmoticonData | undefined
}

interface EmoticonData extends Data {}

Types

This package is fully typed with TypeScript. It exports the additional type Emoticon.

It also registers the Emoticon node type with @types/nlcst in SentenceContentMap. If you’re working with the syntax tree, make sure to import this utility somewhere in your types, as that registers the new node types in the tree.

/**
 * @typedef {import('nlcst-emoticon-modifier')}
 */

import {visit} from 'unist-util-visit'

/** @type {import('nlcst').Root} */
const tree = getNodeSomeHow()

visit(tree, function (node) {
  // `node` can now be a `Emoticon` node.
})

Compatibility

Projects maintained by the unified collective are compatible with maintained versions of Node.js.

When we cut a new major release, we drop support for unmaintained versions of Node. This means we try to keep the current release line, nlcst-emoticon-modifier@^3, compatible with Node.js 16.
