RiTa is implemented in Java and JavaScript, with a common API for both, and is free/libre/open-source via the GPL license.
Note: version 2.0 contains breaking changes -- please check the release notes
npm install rita
<script src="https://unpkg.com/rita"></script>
let RiTa = require('rita');
// to find rhymes
let rhymes = RiTa.rhymes('sweet');
console.log(rhymes);
// 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());
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.
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'
During development it is faster to run tests directly on the source, rather then the built library:
$ npm run test.src
You can also watch the source code and build automatically on any change:
$ npm run watch.src
Please make contributions via fork-and-pull - thanks!
Once you have things running with npm/mocha, you might also try VSCode.
Some of the following extensions may also be useful:
Here you can see the tests in the VSCode Testing view
