Cheepub

Cheepub is EPUB/PDF generator from Markdown. When you have markdown file, you can generate EPUB3 file with just one command: cheepub sample.md.

You can install just use gem command:

$ gem install cheepub

If you use the gem in your project, add this line to your application's Gemfile:

gem 'cheepub'

You can add options --title and --author.

$ cheepub --title foo --author bar source.md

With --latex option, you can generate PDF with LaTeX.

$ cheepub --title foo --author bar --latex source.md

If you use front-matter section like Jekyll, you can execute without any options:

$ cheepub source.md

• -v, --version print version
• --author AUTOR set author of the book
• --title TITLE set title of the book
• --config CONFIG set configuration file
• --latex generate PDF (with LaTeX) file
• --debug set debug mode
• -o, --out OUTFILE set output filename
• --[no-]titlepage add titlepage or not
• --page-direction PAGE_DIRECTION set page direction (ltr or rtl)
• --json output JSON AST and exit
• -h, --help print help

Cheepub uses Kramdown and Gepub. So you can use Kramdown extensions and some other extensions from DenDenMarkdown.

• newpage (separate files): ex. === or ------.
• tate-chu-yoko (horizontal in vertical): ex. ^30^ or ^!?^.
• footnote: ex. [^1] and [^1]: some notes about it.
• ruby: ex. {some base text|some ruby text}

You can define configration with in front-matter or --config option.

Cheepub supports front-matter like Jekyll.

You can write author and title (and other configuration) at front of the markdown file.
