gh-md-toc — is for you if you want to generate TOC for README.md or GitHub's wiki page and don't want to install any additional software.
It's my try to fix a problem:
gh-md-toc is able to process:
- stdin
- local files (markdown files in local file system)
- remote files (html files on github.com)
gh-md-toc tested on Ubuntu only. If you want it on Mac OS X or Windows you better to use a golang based implementation:
It's more solid, reliable and with ability of a parallel processing. And absolutely without dependencies.
$ wget https://raw.githubusercontent.com/ekalinin/github-markdown-toc/master/gh-md-toc
$ chmod a+x gh-md-tocHere's an example of TOC creating for markdown from STDIN:
➥ cat ~/projects/Dockerfile.vim/README.md | ./gh-md-toc -
