This monorepo is a bunch of scripts that crawls dictionaries from several sources, normalizes them, and packs them so that they can each be installed and used in one single way. Dictionaries are not maintained here but they are usable from here.

You can particularly use the packages here as a programmer when integrating with other tools (such as nodehun or nspell) or when making such tools.

These packages are ESM only. In Node.js (version 16+), install with npm:

npm install dictionary-en

👉 Note: replace en with the language code you want.

⚠️ Important: this project itself is MIT, but each index.dic and index.aff file still has its original license!

import en from 'dictionary-en'

console.log(en)
// To do: use `en` somehow

Yields:

{aff: <Buffer>, dic: <Buffer>}

👉 Note: preferred BCP-47 codes are used (according to Unicode CLDR). To illustrate, as American English and Brazilian Portuguese are the most common types of English and Portuguese respectively, they get the codes en and pt.

In total 92 dictionaries are provided.

This example uses dictionary-en in combination with nspell.

npm install dictionary-en nspell

import en from 'dictionary-en'
import nspell from 'nspell'

const spell = nspell(en)
console.log(spell.correct('color'))
console.log(spell.correct('colour'))

Yields:

true
false

This example loads the index.dic and index.aff files located in dictionary-hyw (Western Armenian) from a Node.js JavaScript module (ESM).

It uses a ponyfill (import-meta-resolve) for an experimental Node API.

npm install dictionary-hyw import-meta-resolve

import fs from 'node:fs/promises'
import {resolve} from 'import-meta-resolve'

const base = await resolve('dictionary-hyw', import.meta.url)
const aff = await fs.readFile(new URL('index.aff', base))
const dic = await fs.readFile(new URL('index.dic', base))
console.log(aff, dic)

Follow these steps to use a dictionary on macOS:

1. navigate to the dictionary you want on GitHub, such as dictionaries/$code (replace $code with the language code you want)
2. download the index.aff and index.dic files (as in open them, right-click “Raw”, and “download linked files”)
3. rename the download files to $code.aff and $code.dic
4. move $code.aff and $code.dic into the folder ~/Library/Spelling/
5. go to System Preferences > Keyboard > Text > Spelling and select your added language (it should come with the (Library) suffix and is situated at the bottom)

The packages are typed with TypeScript.

These packages are safe.

To build this project, on macOS, you at least need to install:

• wget: brew install wget (crawling)
• hunspell: brew install hunspell (many dictionaries)
• sed: brew install gnu-sed (crawling, many dictionaries)
• coreutils: brew install coreutils (many dictionaries)
• ispell: brew install ispell (German)

👉 Note: sed and the GNU replacements should be setup in PATH to overwrite macOS defaults.

Dictionaries are not maintained here. Report problems upstream.

Dictionaries are not maintained here. Most languages have a small community or institute that maintains a dictionary, and they often do so on GitHub or similar. Please ask in the issues to request that such a dictionary is included here.

👉 Note: acceptable dictionaries must:

• have a significant affix file (not just a .dic file)
• have an open source license
• have recent contributions
