What is this?

This utility searches emoticon nodes (from nlcst-emoticon-modifier and nlcst-emoji-modifier) that start a sentence and then moves them into the previous sentence.

When should I use this?

This package is a tiny utility that helps when dealing with emoticons in natural language. It’s useful because many people place an emoticon or emoji, representing emotion related to the previous sentence, after a terminal marker. 😒

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 14.14+ and 16.0+), install with npm:

npm install nlcst-affix-emoticon-modifier

In Deno with esm.sh:

import {affixEmoticonModifier} from 'https://esm.sh/nlcst-affix-emoticon-modifier@2'

In browsers with esm.sh:

<script type="module">
  import {affixEmoticonModifier} from 'https://esm.sh/nlcst-affix-emoticon-modifier@2?bundle'
</script>

Use

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

const english = new ParseEnglish()

english.useFirst('tokenizeSentence', emoticonModifier)
english.useFirst('tokenizeParagraph', affixEmoticonModifier)

console.log(inspect(english.parse('Hey. :) How is it going?')))

Yields:

API

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

`affixEmoticonModifier(node)`

Merge emoticons in node into EmoticonNodes.

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-affix-emoticon-modifier')}
 */

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

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

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

Compatibility

Projects maintained by the unified collective are compatible with all maintained versions of Node.js. As of now, that is Node.js 14.14+ and 16.0+. Our projects sometimes work with older versions, but this is not guaranteed.
