An easy way to retrieve common definitions from a GitHub search result.

github-code-scrapper.js

// 1. Do a GitHub search.
// 2. Determine what data to extract.
// 3. Adapt the `lineDetect` and `lineParse` functions.
// 4. ??
// 5. Profit! Run this script on the console.

console.log(
  // Begin: Don't change this ----------------------------------------------------------------------------------
  ((functions) => [...new Set([].slice.call(
    // Select all code results from thi spage.
    document.querySelectorAll('.blob-code-inner')
  ).filter(functions.lineDetect) // Work with the lines we want
   .map(
    line => 
      // Get the repo name.
      line.parentNode.parentNode.parentNode.parentNode.parentNode.querySelector('.d-inline-block > a').innerText 
      + '\t'
      // Get whatever data we want from the line.
      + functions.lineParse(line)
  ))].join('\r\n'))({
  // End: Don't change this ----------------------------------------------------------------------------------
    lineDetect: (line) => line.innerText.indexOf('#ENV') === -1 
      && line.innerText.indexOf('# ENV') === -1
      && line.innerText.indexOf('NODE_VERSION') > -1,
    lineParse: (line) => line.innerText.split('=')[1]
  })
);

// Sample output: Get jQuery versions from different repos:
// URL: https://github.com/search?utf8=%E2%9C%93&q=package.json+jquery+dependencies+language%3Ajson&type=Code
// lineDetect: (line) => line.innerText.indexOf('"jquery"') > -1,
// lineParse: (line) => line.innerText.replace(/"/g, '')
