@sagemath/pari

Pari without GMP

DEPRECATED: See the @sagemath/pari-gmp package instead, which is only slightly larger and significantly faster. Future development work will go there.

Quickstart

Install the package

npm i @sagemath/pari

Then use it from node.js as follows:

> (async ()=>global.gp = await require('@sagemath/pari')())()
Promise { <pending> }
> gp('factor(2^128 + 1)')
'%1 = 5\n'
> gp('\\p100')
   realprecision = 105 significant digits (100 digits displayed)
'\n'
> gp('contfrac(Pi)')
'%4 = [3, 7, 15, 1, 292, 1, 1, 1, 2, 1, 3, 1, 14, 2, 1, 1, 2, 2, 2, 2, 1, 84, 2, 1, 1, 15, 3, 13, 1, 4, 2, 6, 6, 99, 1, 2, 2, 6, 3, 5, 1, 1, 6, 8, 1, 7, 1, 2, 3, 7, 1, 2, 1, 1, 12, 1, 1, 1, 3, 1, 1, 8, 1, 1, 2, 1, 6, 1, 1, 5, 2, 2, 3, 1, 2, 4, 4, 16, 1, 161, 45, 1, 22, 1, 2, 2, 1, 4, 1, 2, 24, 1, 2, 1, 3, 1, 2, 1, 1, 10, 2, 5]\n'

Build from source

You need to install emscripten. Then do

npm run build

Problems/TODO

Interrupting running code

Try gp(factor(2^2001+1)) and hit control+c to try to interrupt the running computation. It terminates the Node.js interpreter as well, and there is no way to catch this.

Using with webpack5 in your browser

Make it easy to use this in frontend browser code bundled up using webpack.
