RiTa: tools for generative natural language
RiTa is implemented in JavaScript and Java, with a common API for both, and is free/libre/open-source via the GPL license.
Features in v3.0
- Smart lexicon search for words matching part-of-speech, syllable, stress and rhyme patterns
- Fast, heuristic algorithms for inflection, conjugation, stemming, tokenization, and more
- Letter-to-sound engine for feature analysis of arbitrary words (with/without lexicon)
- Integration of the RiScript scripting language, designed for writers
- New options for generation via grammars and Markov chains
- Published in ESM, CommonJS and as an IIFE
Note: version 3.0 contains breaking changes -- please check the release notes
Installation
- For node:
npm install rita
- For browsers:
<script src="https://unpkg.com/rita"></script>
- For developers
Example (node)
let RiTa = require('rita');
// to analyze a sentence
let data = RiTa.analyze("The elephant took a bite!");
console.log(data);
// to load a grammar
let grammar = RiTa.grammar(jsonRules);
console.log(grammar.expand());
API
RiScript
RiScript is a writer-focused scripting language integrated with RiTa. It enables simple generative primitives within plain text for dynamic expansion at runtime. RiScript primitives can be used as part of any RiTa grammar or executed directly using RiTa.evaluate(). For more info, see this interactive notebook.
Developing
To install/build the library and run tests (with npm/mocha and node v14.x):
$ git clone https://github.com/dhowe/ritajs.git
$ cd ritajs
$ npm install
$ npm run build
$ npm run test
If all goes well, you should see a list of successful tests and find the library built in 'dist'
Please make contributions via fork-and-pull - thanks!
Visual Studio Code
Once you have things running with npm/mocha, you might also try VSCode.
Some of the following extensions may also be useful:
- hbenl.vscode-mocha-test-adapter
- hbenl.vscode-test-explorer
- ms-vscode.test-adapter-converter
Here you can see the tests in the VSCode Testing view

Quick Start
A simple sketch
Create a new file on your desktop called 'test.html' with the following lines, save and drag it into a browser:
<html>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<script src="https://unpkg.com/rita"></script>
<script>
window.onload = function() {
let words = RiTa.tokenize("The elephant took a bite!");
$('#content').text(words);
};
</script>
<div id="content" width=200 height=200></div>
<html>
With p5.js
Create a new file on your desktop called 'test.html' and download the latest rita.js from here, add the following lines, save and drag it into a browser:
<html>
<script src="https://unpkg.com/p5"></script>
<script src="https://unpkg.com/rita"></script>
<script>
function setup() {
createCanvas(200,200);
background(50);
textSize(20);
noStroke();
let words = RiTa.tokenize("The elephant took a bite!")
for (let i=0; i < words.length; i++) {
text(words[i], 50, 50 + i*20);
}
}
</script>
</html>
With node.js and npm
To install: $ npm install rita
let RiTa = require('rita');
let data = RiTa.analyze("The elephant took a bite!");
console.log(data);
