Markdown is a popular format for writing documentation among developers. However, distributing Markdown documents in a polished PDF format, especially with GitHub styling, requires some specific tools. This guide explores how to use the ‘ghpdf’ command-line tool to achieve this.
Introduction to ‘ghpdf’ CLI
The ‘ghpdf’ CLI tool is designed to convert Markdown files into PDF documents styled like GitHub’s markdown rendering. This is particularly useful for developers, DevOps engineers, and SREs who need to share documentation in a consistent format.
Setting Up ‘ghpdf’
To start using ‘ghpdf’, you need to install it via Python’s package manager, pip:
pip install ghpdf
Basic Usage: Single File Conversion
Once installed, converting a single Markdown file is straightforward:

Furthermore, it can read from standard input, making it versatile for automated pipelines:
cat CHANGELOG.md | ghpdf -o changelog.pdf
Integration in CI/CD Pipelines
Integrating ‘ghpdf’ into CI/CD pipelines is beneficial for DevOps workflows, allowing for automated documentation generation within Docker containers, GitHub Actions, or GitLab CI. This streamlines the documentation process and ensures consistency.
Comparison with Other Tools
While there are other Markdown to PDF converters, ‘ghpdf’ differentiates itself by specifically offering GitHub-styled output, which can be crucial for consistency when sharing with stakeholders familiar with GitHub’s interface.
