Github markdown previewing straight from your shell.

octodown

Ever wanted to easily preview what your markdown would look like exactly on Github? Ever wanted to do that from inside of a Terminal?

Octodown uses the same parsers and CSS that Github uses for their markdown rendering. Github markdown styling looks beautiful, so it is Octodown's primary goal to reproduce it as faithfully as possible.

Features

• 🆕 Edit your markdown like a boss with LiveReload.

  • octodown README.md

• Uses the same markdown parsers and CSS as Github for true duplication.

  • Yes emojis are included. 😈

• Fast. octodown uses native parsers to ensure performance.

• Multiple CSS styles.

  • octodown --style atom README.md
  • The github markdown (default)
  • The atom text editor markdown

• Properly parses STDIN.

  • cat README.md | octodown --stdin

Installation

Requirements: Ruby >= 2.0

1. Install icu4c and cmake:

• Mac: brew install icu4c cmake pkg-config
• Apt: sudo apt-get install -y libicu-dev cmake pkg-config ruby-dev

1. Install octodown:

• If you have a non-system Ruby (highly recommended): gem install octodown
• Else: sudo gem install octodown

Usage in VIM (optional):

• Use asyncrun.vim:

  " Plug 'skywind3000/asyncrun.vim' in your vimrc or init.nvim
  
  :AsyncRun octodown %
  
  " or, run whenever a mardown document is opened
  
  autocmd FileType markdown :AsyncRun octodown %

• Use Dispatch and add this to your ~/.vimrc:

  " Use octodown as default build command for Markdown files
  autocmd FileType markdown let b:dispatch = 'octodown %'

• Caveat: make sure you follow the directions on the Dispatch README.md and make sure that the correct version of Ruby (the one which as Octodown install as a Gem), is used.

Usage

1. Keeping it simple (choose your files from a menu):

• octodown

1. Markdown preview styling:

• octodown --style atom README.md

1. Unix lovers:

• echo '# Hello world!' | octodown --raw --stdin > index.html

Notes

1. With --stdin, octodown will read STDIN until EOF is reached.

• In order to work with this mode, type what you want into the input, then press Ctrl-D when finished.
