blame-js

blame-js compares an array of source codes and outputs information about where each line originates from. Its behaviour is similar to the blame functionality that is integrated in Git.

Install

npm install --save blame-js

Usage

Pay attention to the order of items in the array: the first one in the array is the newest. The items can either be simple texts or objects. The latter requires to pass an getCode and getOrigin function to be passed in the options (see example 2).

const blamejs = require('blame-js');
// or alternatively in ES6 syntax:
// import blamejs from 'blame-js';

/*
Result:
[ { origin: 0, value: 'a' },
  { origin: 0, value: 'b' },
  { origin: 2, value: 'c' } ]
*/
blamejs([`a
b
c`,
`c`,
`a
b
c`
])

/*
Result:
[ { origin: 'Commit #3', value: 'a' },
  { origin: 'Commit #3', value: 'b' },
  { origin: 'Commit #1', value: 'c' } ]
*/
blamejs(
  [
    {
      commit: 'Commit #3',
      code: `a
b
c`,
    },
    {
      commit: 'Commit #2',
      code: `c`,
    },
    {
      commit: 'Commit #1',
      code: `a
b
c`,
    },
  ],
  {
    getCode: item => item.code,
    getOrigin: item => item.commit,
  },
)
