creates a gitlab markdown table of contents for a README.md page

gitlab-markdown-toc.js

// quick and dirty snippet to creates a gitlab markdown table of contents for a README.md page
// preview gitlab page and paste in browser console
var str = "";
$('.file-content')
  .find('h1, h2, h3, h4, h5, h6, h7')
  .each((i, node) => {
    // node.tagName is H1 H2...
    let indent = Number(node.tagName[1]) - 1;
    // markdown mested lists are
    // - xxx
    //    - yyy etc
    let tabs = '               '.substr(0, 3 * indent);
    let linkName = node.textContent.trim();
    let linkAnchor = node.querySelector('a').id;
    str += `\n${tabs}- [${linkName}](#${linkAnchor})`;
  });
console.log(str);

Very nice snippet!

On my GitLab the script adds some excessive text to each toc entry, like "user-content-", e.g.:

      - [Tips](#user-content-tips)

Otherwise everything is fine, thank you!

Hi,
now you just need adding [[TOC]] or [[TOC]] to the Description section of the README.md file to get the TOC:
