github-markdown-toc

This is a golang based implementation of the github-markdown-toc tool.

The advantages of this implementation:

• no dependencies (no need curl, wget, awk, etc.)
• cross-platform (support for Windows, Mac OS, etc.)
• regexp for parsing TOC
• parallel processing of multiple documents

Attention: gh-md-toc is able to work properly only if your machine is connected to the Internet.

Installation

Precompiled binaries

See the releases page, "Downloads" section:

• https://github.com/ekalinin/github-markdown-toc.go/releases

For example:

$ wget https://github.com/ekalinin/github-markdown-toc.go/releases/download/1.1.0/gh-md-toc.linux.amd64.tgz
$ tar xzvf gh-md-toc.linux.amd64.tgz

Usage

STDIN

Here's an example of TOC creating for markdown from STDIN:

➥ cat ~/projects/Dockerfile.vim/README.md | ./gh-md-toc
  * [Dockerfile.vim](#dockerfilevim)
  * [Screenshot](#screenshot)
  * [Installation](#installation)
        * [OR using Pathogen:](#or-using-pathogen)
        * [OR using Vundle:](#or-using-vundle)
  * [License](#license)

Local files

Here's an example of TOC creating for a local README.md:

➥ ./gh-md-toc ~/projects/Dockerfile.vim/README.md                                                                                                                                                Вс. марта 22 22:51:46 MSK 2015

        * [OR using Pathogen:](#or-using-pathogen)
        * [OR using Vundle:](#or-using-vundle)
  * [License](#license)

Remote files

And here's an example, when you have a README.md like this:

• README.md without TOC

And you want to generate TOC for it.

There is nothing easier:

➥ ./gh-md-toc https://github.com/ekalinin/envirius/blob/master/README.md

That's all! Now all you need — is copy/paste result from console into original README.md.

And here is a result:

• README.md with TOC

Multiple files

It supports multiple files as well:

➥ ./gh-md-toc \
    https://github.com/aminb/rust-for-c/blob/master/hello_world/README.md \
    https://github.com/aminb/rust-for-c/blob/master/control_flow/README.md \
    https://github.com/aminb/rust-for-c/blob/master/primitive_types_and_operators/README.md \
    https://github.com/aminb/rust-for-c/blob/master/unique_pointers/README.md

  * [Hello world](https://github.com/aminb/rust-for-c/blob/master/hello_world/README.md#hello-world)

  * [Control Flow](https://github.com/aminb/rust-for-c/blob/master/control_flow/README.md#control-flow)
    * [If](https://github.com/aminb/rust-for-c/blob/master/control_flow/README.md#if)
    * [Loops](https://github.com/aminb/rust-for-c/blob/master/control_flow/README.md#loops)
    * [For loops](https://github.com/aminb/rust-for-c/blob/master/control_flow/README.md#for-loops)
    * [Switch/Match](https://github.com/aminb/rust-for-c/blob/master/control_flow/README.md#switchmatch)
    * [Method call](https://github.com/aminb/rust-for-c/blob/master/control_flow/README.md#method-call)

  * [Primitive Types and Operators](https://github.com/aminb/rust-for-c/blob/master/primitive_types_and_operators/README.md#primitive-types-and-operators)

  * [Unique Pointers](https://github.com/aminb/rust-for-c/blob/master/unique_pointers/README.md#unique-pointers)

Processing of multiple documents is in parallel mode since version 0.4.0 You can use (old) serial mode by passing option --serial in the console:

$ ./gh-md-toc --serial ...

Timings:

➥ time (./gh-md-toc --serial README.md ../envirius/README.ru.md ../github-toc/README.md > /dev/null)

real    0m1.200s
user    0m0.040s
sys     0m0.004s

➥ time (./gh-md-toc README.md ../envirius/README.ru.md ../github-toc/README.md > /dev/null)

real    0m0.784s
user    0m0.036s
sys     0m0.004s

Combo

You can easily combine both ways:

➥ ./gh-md-toc \
    ~/projects/Dockerfile.vim/README.md \
    https://github.com/ekalinin/sitemap.s/blob/master/README.md

  * [Dockerfile.vim](~/projects/Dockerfile.vim/README.md#dockerfilevim)
  * [Screenshot](~/projects/Dockerfile.vim/README.md#screenshot)
  * [Installation](~/projects/Dockerfile.vim/README.md#installation)
        * [OR using Pathogen:](~/projects/Dockerfile.vim/README.md#or-using-pathogen)
        * [OR using Vundle:](~/projects/Dockerfile.vim/README.md#or-using-vundle)
  * [License](~/projects/Dockerfile.vim/README.md#license)

  * [sitemap.js](https://github.com/ekalinin/sitemap.js/blob/master/README.md#sitemapjs)
    * [Installation](https://github.com/ekalinin/sitemap.js/blob/master/README.md#installation)
    * [Usage](https://github.com/ekalinin/sitemap.js/blob/master/README.md#usage)
    * [License](https://github.com/ekalinin/sitemap.js/blob/master/README.md#license)

Use --start-depth=INT to control the starting header level (i.e. include only the levels starting with INT)

➥ ./gh-md-toc --start-depth=1 ~/projects/Dockerfile.vim/README.md

Github token

All your tokents are here.

Bash/ZSH auto-complete

Just add a simple command into your ~/.bashrc or ~/.zshrc:

# for zsh
eval "$(gh-md-toc --completion-script-zsh)"

# for bash
eval "$(gh-md-toc --completion-script-bash)"

Alpine Linux

Alpine Linux uses musl instead of glibc by default. If you install binutils and run…

apk add binutils && \
readelf -l /path/to/gh-md-toc

…you'll see that it relies on /lib64/ld-linux-x86-64.so.2 as its interpreter. You can solve this by installing libc6-compat alongside downloading the Linux amd64 build.

apk add libc6-compat
