Chromium Processor

Purpose

Converts HTML files to PDF using headless Chromium (Google Chrome).

How It Works

Discovers .html files in the configured scan directory (default: out/marp) and runs headless Chromium with --print-to-pdf on each file, producing a PDF output.

This is typically used as a post-processing step after another processor (e.g., Marp) generates HTML files.

Source Files

• Input: out/marp/**/*.html (default scan directory)
• Output: out/chromium/{relative_path}.pdf

Configuration

[processor.chromium]
chromium_bin = "google-chrome"            # The Chromium/Chrome executable to run
args = []                                 # Additional arguments to pass to Chromium
output_dir = "out/chromium"               # Output directory for PDFs
extra_inputs = []                         # Additional files that trigger rebuilds when changed
