        gh-md-toc

=========

[![CI](https://github.com/ekalinin/github-markdown-toc/actions/workflows/ci.yml/badge.svg?branch=master)](https://github.com/ekalinin/github-markdown-toc/actions/workflows/ci.yml)

![GitHub release (latest by date)](https://img.shields.io/github/v/release/ekalinin/github-markdown-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](https://github.com/isaacs/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](https://github.com/ekalinin/github-markdown-toc.go)

It's more solid, reliable and with ability of a parallel processing. And

absolutely without dependencies.

```bash

$ 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:

```bash

➥ 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:

```bash

➥ ./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](https://github.com/ekalinin/envirius/blob/f939d3b6882bfb6ecb28ef7b6e62862f934ba945/README.md)

And you want to generate TOC for it.

There is nothing easier:

```bash

➥ ./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](https://github.com/ekalinin/envirius/blob/24ea3be0d3cc03f4235fa4879bb33dc122d0ae29/README.md)

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

```bash

➥ ./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:

```bash

➥ ./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)

```

Combo

-----

You can easily combine both ways:

```bash

➥ ./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)

```

Auto insert and update TOC

--------------------------

Just put into a file these two lines:

```

```

And run:

```bash

$ ./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)

   * [Dependency](#dependency)

!! 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'

```

Now check the same file:

```bash

➜ grep -A15 "<\!\-\-ts" README.test.md

   * [gh-md-toc](#gh-md-toc)

   * [Table of contents](#table-of-contents)

   * [Installation](#installation)

   * [Usage](#usage)

      * [STDIN](#stdin)

      * [Local files](#local-files)

      * [Remote files](#remote-files)

      * [Multiple files](#multiple-files)

      * [Combo](#combo)

      * [Auto insert and update TOC](#auto-insert-and-update-toc)

   * [Tests](#tests)

   * [Dependency](#dependency)

```

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](https://github.com/settings/tokens).

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:

```bash

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

Table of Contents

=================

* [github\-markdown\-toc](#github-markdown-toc)

* [Table of Contents](#table-of-contents)

* [Installation](#installation)

* [Tests](#tests)

* [Usage](#usage)

* [LICENSE](#license)

```

Or from a file:

```bash

➥ echo "2a2dab...563" > ./token.txt

➥ ./gh-md-toc README.md

Table of Contents

=================

* [github\-markdown\-toc](#github-markdown-toc)

* [Table of Contents](#table-of-contents)

* [Installation](#installation)

* [Tests](#tests)

* [Usage](#usage)

* [LICENSE](#license)

```
