# GiNaC-WASM

WebAssembly bindings for the [GiNaC computer algebra system](https://www.ginac.de/)

Demo frontend: https://daninet.github.io/ginac-wasm

## Usage

```js

const { initGiNaC, getFactory } = require('ginac-wasm');

(async () => {

  const GiNaC = await initGiNaC(require.resolve('ginac-wasm/dist/ginac.wasm'));

  const g = getFactory();

  console.log(

    GiNaC([

      // 2 * 3 = 6

      g.mul(g.numeric('2'), g.numeric('3')),

      // x + 2x = 3x

      g.add(g.symbol('x'), g.mul(g.numeric('2'), g.symbol('x'))),

      // (2*sin(x))' = 2*cos(x)

      g.diff(g.mul(g.numeric('2'), g.sin(g.symbol('x'))), g.symbol('x')),

      // internal parser of GiNaC

      g.parse('x^3 + 3*x + 1') 

    ]),

  );

  console.log(

    GiNaC([

      g.numeric('2'),

      g.numeric('3'),

      // reference first and second items from the array => 2*3 = 6

      g.mul(g.ref(0), g.ref(1))

    ]),

  );

  // besides the string output format,

  // it can also generate traversable json structures

  console.dir(

    GiNaC([

      // 2*sin(x)

      g.mul(g.numeric('2'), g.sin(g.symbol('x'))),

    ], { json: true }),

    { depth: null }

  );

})();

```
