gh-md-toc

gh-md-toc — is for you if you want to generate TOC (Table Of Content) for a README.md or a GitHub wiki page without installing additional software.

It's my try to fix a problem:

github/issues/215

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, and macOS High Sierra (gh-md-toc release 0.4.9). If you want it on Windows, you better to use a golang based implementation:

github-markdown-toc.go

It's more solid, reliable and with ability of a parallel processing. And absolutely without dependencies.

Installation

Linux (manual installation)

$ wget https://raw.githubusercontent.com/ekalinin/github-markdown-toc/master/gh-md-toc
$ chmod a+x gh-md-toc

MacOS (manual installation)

$ curl https://raw.githubusercontent.com/ekalinin/github-markdown-toc/master/gh-md-toc -o gh-md-toc
$ chmod a+x gh-md-toc

Linux or MacOS (using Basher)

$ basher install ekalinin/github-markdown-toc
# `gh-md-toc` will automatically be available in the PATH

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


Table of Contents
=================

  * [Dockerfile.vim](#dockerfilevim)
  * [Screenshot](#screenshot)
  * [Installation](#installation)
        * [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

Table of Contents
=================

  * [envirius](#envirius)
    * [Idea](#idea)
    * [Features](#features)
  * [Installation](#installation)
  * [Uninstallation](#uninstallation)
  * [Available plugins](#available-plugins)
  * [Usage](#usage)
    * [Check available plugins](#check-available-plugins)
    * [Check available versions for each plugin](#check-available-versions-for-each-plugin)
    * [Create an environment](#create-an-environment)
    * [Activate/deactivate environment](#activatedeactivate-environment)
      * [Activating in a new shell](#activating-in-a-new-shell)
      * [Activating in the same shell](#activating-in-the-same-shell)
    * [Get list of environments](#get-list-of-environments)
    * [Get current activated environment](#get-current-activated-environment)
    * [Do something in environment without enabling it](#do-something-in-environment-without-enabling-it)
    * [Get help](#get-help)
    * [Get help for a command](#get-help-for-a-command)
  * [How to add a plugin?](#how-to-add-a-plugin)
    * [Mandatory elements](#mandatory-elements)
      * [plug_list_versions](#plug_list_versions)
      * [plug_url_for_download](#plug_url_for_download)
      * [plug_build](#plug_build)
    * [Optional elements](#optional-elements)
      * [Variables](#variables)
      * [Functions](#functions)
    * [Examples](#examples)
  * [Example of the usage](#example-of-the-usage)
  * [Dependencies](#dependencies)
  * [Supported OS](#supported-os)
  * [Tests](#tests)
  * [Version History](#version-history)
  * [License](#license)
  * [README in another language](#readme-in-another-language)

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

If you do not want to copy from console you can add > YOURFILENAME.md at the end of the command like ./gh-md-toc https://github.com/ekalinin/envirius/blob/master/README.md > table-of-contents.md and this will store the table of contents to a file named table-of-contents.md in your current folder.

And here is a result:

README.md with TOC

Moreover, it's able to work with GitHub's wiki pages:

➥ ./gh-md-toc https://github.com/ekalinin/nodeenv/wiki/Who-Uses-Nodeenv

Table of Contents
=================

  * [Who Uses Nodeenv?](#who-uses-nodeenv)
    * [OpenStack](#openstack)
    * [pre-commit.com](#pre-commitcom)

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)

    * [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)

    * [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)

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)

Auto insert and update TOC

Just put into a file these two lines:

<!--ts-->
<!--te-->

And run:

$ ./gh-md-toc --insert README.test.md

Table of Contents
=================

   * [gh-md-toc](#gh-md-toc)
   * [Installation](#installation)
   * [Usage](#usage)
      * [STDIN](#stdin)
      * [Local files](#local-files)
      * [Remote files](#remote-files)
      * [Multiple files](#multiple-files)
      * [Combo](#combo)
   * [Tests](#tests)

!! TOC was added into: 'README.test.md'
!! Origin version of the file: 'README.test.md.orig.2018-02-04_192655'
!! TOC added into a separate file: 'README.test.md.toc.2018-02-04_192655'


<!-- Created by https://github.com/ekalinin/github-markdown-toc -->

Now check the same file:

➜ grep -A15 "<\!\-\-ts" README.test.md
<!--ts-->
   * [gh-md-toc](#gh-md-toc)
   * [Table of contents](#table-of-contents)

   * [Dependency](#dependency)

<!-- Added by: <your-user>, at: 2018-02-04T19:38+03:00 -->

<!--te-->

Next time when your file will be changed just repeat the command (./gh-md-toc --insert ...) and TOC will be refreshed again.

GitHub token

All your tokens are here.

You will need them if you get an error like this:

Parsing local markdown file requires access to github API
Error: You exceeded the hourly limit. See: https://developer.github.com/v3/#rate-limiting
or place github auth token here: ./token.txt

A token can be used as an env variable:

➥ GH_TOC_TOKEN=2a2dab...563 ./gh-md-toc README.md
