Hilbert.js

Hilbert.js is a JavaScript library for expression parsing, simplification, and MathML rendering. It was developed for Mathigon.org, an award-winning mathematics education project.

Open Issues

Note: this library is still under development, and not ready for production use.

• Support for functions with subscripts (e.g. log_a(b)).
• Support for super+subscripts (e.g. a_n^2 or a^2_n).
• Support for large operators (sum, product and integral).
• Parse ^ operator from right to left (e.g. 2^2^2 == 2^(2^2)).
• Add evaluate(), toString() and toMathML() methods for many more special functions.
• Write CAS Expression simplification algorithms, equals() and same() methods.
• Write many more tests. Visual tests for MathML.

Usage

First, install hilbert.js from NPM using

npm install @mathigon/hilbert --save

Hilbert.js uses ES6 imports. While some browsers and platforms now support this feature, we recommend using a transpiler such as Babel or Rollup. Make sure that you configure your compiler to correctly resolve these imports. For Rollup, we recommend using the rollup-plugin-node-resolve plugin.

Now, simply import all functions and classes you need, using

import { Expression } from '@mathigon/hilbert'
