Sakusei

Sakusei (作成) — from the Japanese words meaning "creation," "making," or "craft."

Like a master artisan refining their craft, Sakusei transforms raw Markdown into beautifully crafted PDF documents. Every document is an act of creation — structured, styled, and brought to life with precision.

The name embodies the philosophy behind this tool: documents aren't just generated, they're crafted.

Sakusei is a build system for creating PDF documents from Markdown source files. It supports:

• Markdown to PDF conversion via md-to-pdf
• ERB template evaluation for dynamic content
• Hierarchical style packs for consistent document styling
• File inclusion for multi-file documents
• PDF concatenation for combining multiple documents

# Add the tap and install
brew tap keithrowell/sakusei https://github.com/keithrowell/sakusei/homebrew-tap
brew install sakusei

gem install sakusei

git clone https://github.com/keithrowell/sakusei
cd sakusei
bundle install
rake install

Prerequisites:

• Ruby 3.0+
• Node.js (for md-to-pdf)
• pdfunite or pdftk (for PDF concatenation)

sakusei build document.md

Or simply (build is the default command):

sakusei document.md

Extension is optional - .md, .text, or .markdown will be tried:

sakusei document    # Looks for document.md, document.text, or document.markdown

Auto-open after building:

sakusei document.md --open

sakusei init my_company

sakusei concat part1.pdf part2.pdf -o combined.pdf

Style packs are stored in .sakusei/style_packs/ directories. Sakusei searches for style packs by walking up the directory tree from your source file.

.sakusei/
└── style_packs/
    └── my_company/
        ├── config.js      # md-to-pdf configuration
        ├── style.css      # Stylesheet
        ├── header.html    # Header template
        └── footer.html    # Footer template

Include other markdown files in your document:

# My Document

<!-- @include ./introduction.md -->

<!-- @include ./chapter1.md -->

Use ERB for dynamic content:

# Report Generated <%= today %>

Environment: <%= env('RAILS_ENV', 'development') %>

Insert page breaks in your markdown using HTML:

# Chapter 1

Content here...

<div class="page-break"></div>

# Chapter 2

More content...

Available classes:

• .page-break or .page-break-after - Break after this element
• .page-break-before - Break before this element

The base stylesheet automatically prevents page breaks inside these elements:

• Tables (including rows)
• Code blocks (<pre>)
• Blockquotes
• Images
• Figures and captions
• Definition lists (<dl>, <dt>, <dd>)
• Details/summary sections
• Math blocks (KaTeX)
• Custom elements: .admonition, .callout, .card, .box

To force keep-together on any element, add the .keep-together class:

<div class="keep-together">

This content will not be split across pages.

| Table | Data |
|-------|------|
| A     | 1    |
| B     | 2    |

</div>

Create a .sakusei_build file for complex builds:

steps:
  - command: build
    files:
      - cover.md
      - content/*.md
    output: document.pdf
    style: my_company
