Install

Using Ruby:

Using Docker:

$ alias madness='docker run --rm -it -v $PWD:/docs -p 3000:3000 dannyben/madness'

Design Intentions

Madness was designed in order to provide easy browsing, viewing and searching for local, markdown based documentation directories.

Feature Highlights

Usage

Go to any directory that contains markdown files and run:

$ madness

And open http://localhost:3000 in your browser.

For more options, run:

$ madness --help

Directory Conventions

Madness expects to be executed in a documentation directory.

A documentation directory contains only markdown files (*.md) and sub directories that contain more markdown files.

The server will consider the file index.md or README.md in any directory as the main file describing this directory, where index.md has priority.

The navigation sidebar will show all the sub directories and files in the same directory as the viewed file.

Example structure:

./
├── README.md
├── File.md
├── Another File.md
├── Folder
│   ├── File.md
│   └── image.png
└── Another Folder
    ├── README.md
    └── File.md

Configuration File

All the command line arguments can also be configured through a configuration file. Create a file named .madness.yml in your documentation directory, and modify any of the settings below.

# .madness.yml
path: '.'
port: '3000'
bind: '0.0.0.0'
sidebar: true
auto_h1: true
auto_nav: true
highlighter: true
line_numbers: true
copy_code: true
index: false
search_limit: 100
dtoc: Table of Contents
theme: _theme
open: false

For convenience, you can get a template config file by running:

$ madness create config

Madness comes with a full text search page. To activate it, you need to generate a search index by running madness --index or madness path/to/docs --index.

This will create an _index sub folder, and will add a new search page to your documentation server.

You will need to run this command from time to time, as your documents change or new documents are added.

Images and Static Files

You can put images and other asset files anywhere in your documentation folder.

When linking to other pages or images in your documentation folder, simply use the URL relative to the markdown file.

For example, if you have a folder named subfolder that contains a README.md and a nice-picture.png, showing it in your README is done by this markdown:

![alt text](nice-picture.png)

If you wish to link to images or pages in a different folder, simply specify the path relative to the homepage:

![alt text](/images/nice-picture.png)

Automatic H1

If your markdown document does not start with a level 1 heading, it will be automatically added based on the file name.

Table of Contents Generation

You can use the madness --toc FILENAME command to generate a “Table of Contents” markdown file.

Hidden Directories

Directories that are made only of lowercase letters, underscoes, dash and/or numbers (/^[a-z_\-0-9]+$/) will not be displayed in the navigation. In other words, directories must have at least one uppercase letter or a space to be recognized as a documentation directory.

Controlling Sort Order

To control the sort order of the automatically generated navigation elements, simply perfix your files and directories with digits followed by a dot and a space, just like you would create an ordered list in Markdown. The numbers will be omitted when they are displayed.

./
├── 1. Some file or folder
└── 2. Another file or folder

Basic Authentication

To add basic authentication, use the --auth user:password command line argument or the equivalent auth configuration option.

If you wish to avoid storing the basic authentication credentials in the configuration file, you may use ERB tags to load the credentials from environment variables:

auth: <%= ENV['BASIC_AUTH'] %>

Customizing Theme

There are two ways to change how Madness looks.

Option 1: Change CSS and HTML (Slim)

In order to have complete control over the CSS and generated HTML, you can override the views and styles. Views are provided as Slim templates, and CSS is provided as SCSS.

Madness comes with a command that copies the default theme to a folder of your choice, where you can customize it to your taste. Run:

$ madness create theme my_theme

Where my_theme is the folder that will be created.

To use the created theme, simply run Madness with the --theme my_theme option.

$ madness --theme my_theme

Option 2: Change CSS only

If you are looking to implement a smaller CSS change, follow these steps:

Note that this functionality is not guaranteed to stay as is in future versions of madness.

Forcing HTTPS Connection

To have Madness redirect HTTP traffic to HTTPS, set this environment variable:

$ export MADNESS_FORCE_SSL=1

Docker Image

Madness server is also available as a docker image.

This command will start the server on localhost:3000, with the current directory as the markdown documentation folder

$ docker run --rm -it -v $PWD:/docs -p 3000:3000 dannyben/madness

You may create an alias for convenience:

$ alias madness='docker run --rm -it -v $PWD:/docs -p 3000:3000 dannyben/madness'
$ medness --help
