md-to-pdf

When the user asks to convert a markdown file to PDF, follow these steps exactly: ## Step 1 — Confirm the input file Ask the user for the path to the `.md` file if not already provided. Confirm the output PDF path (default: same folder, same name, `.pdf` extension). ## Step 2 — Convert markdown to styled HTML Run this command (replace INPUT and OUTPUT paths): ```bash pandoc "INPUT.md" \ -o "OUTPUT.html" \ --standalone \ --metadata title="Document" \ --css=/dev/stdin <<'EOF' body { font-family: "Helvetica Neue", Arial, sans-serif; max-width: 800px; margin: 40px auto; padding: 0 40px; font-size: 13px; line-height: 1.7; color: #1a1a1a; } h1 { font-size: 26px; font-weight: 700; margin-bottom: 4px; } h2 { font-size: 16px; font-weight: 700; margin-top: 32px; border-bottom: 1px solid #e0e0e0; padding-bottom: 6px; } strong { font-weight: 600; } table { width: 100%; border-collapse: collapse; margin: 16px 0; font-size: 12px; } th { background: #f5f5f5; padding: 8px; text-align: left; border: 1px solid #ddd; } td { padding: 8px; border: 1px solid #ddd; } hr { border: none; border-top: 1px solid #e0e0e0; margin: 24px 0; } ul, ol { padding-left: 20px; } li { margin-bottom: 6px; } EOF ``` ## Step 3 — Print HTML to PDF using Chrome ```bash "/Applications/Google Chrome.app/Contents/MacOS/Google Chrome" \ --headless \ --disable-gpu \ --no-sandbox \ --print-to-pdf="OUTPUT.pdf" \ --print-to-pdf-no-header \ --no-pdf-header-footer \ "file://OUTPUT.html" ``` Note: encode spaces in the file path as `%20` in the `file://` URL. ## Step 4 — Clean up and confirm Delete the intermediate HTML file: ```bash rm "OUTPUT.html" ``` Tell the user the PDF is ready and give them the full path. ## Requirements - `pandoc` must be installed (`which pandoc` to check) - Google Chrome must be at `/Applications/Google Chrome.app/` (standard Mac install) - Works on macOS only in this configuration ## Error handling - If `pandoc` is not found: tell the user to run `brew install pandoc` - If Chrome is not at the expected path: check with `ls /Applications/ | grep -i chrome` and adjust the path - If the PDF is 0 bytes: the `file://` URL likely has unencoded spaces — encode them as `%20`
