Package Exports

jisg

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (jisg) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

jisg - JavaScript Integer Sequence Generators

Implementations of select OEIS integer sequences in JavaScript, portially inspired by intseq.

Install

yarn add jisg

Usage

Build System

import {A000045} from 'jisg'
const generator = A000045()
for (let i=0; i<43; i++) {
   console.log(generator.next().value)
}

Node

const {A000045} = require('jisg')
for (let i of A000045()) {
  console.log(i)
}

Adding a Sequence Generator

Fork me and clone your repo locally.
Copy the beginning of the sequence from The On-line Encyclopedia of Integer Sequences into a new entry in OEIS_START_SAMPLES in main.test.ts. Append an "n" to each integer to make them BigInts (/(\d+)/\1n/).
Create the source file in src/oeis/ using the OEIS number (eg. "A000001.ts") and add an entry in main.ts.
Implement the generator so that the test case passes (eg. yarn test -t A000001). If the test takes longer than 10 seconds, remove integers from the end of the sample until it takes less than 10 seconds.
Check code style and test coverage with yarn prepublish and fix any issues.
