Multi-Chapter Assembly

build-manual.js

const pandoc = require('pandoc');
const fs = require('fs');
const path = require('path');

async function buildManual(config) {
  const chapters = [
    { title: 'Getting Started', files: ['intro.md', 'installation.md', 'quickstart.md'] },
    { title: 'User Guide', files: ['configuration.md', 'features.md', 'advanced.md'] },
    { title: 'API Reference', files: ['api/*.md'] },
    { title: 'Appendix', files: ['glossary.md', 'changelog.md'] }
  ];

  // Combine all Markdown files
  let combined = '';

  for (const chapter of chapters) {
    combined += `# ${chapter.title}\n\n`;

    for (const filePattern of chapter.files) {
      const files = glob.sync(filePattern, { cwd: config.docsDir });
      for (const file of files) {
        const content = fs.readFileSync(path.join(config.docsDir, file), 'utf8');
        // Adjust heading levels
        const adjusted = adjustHeadings(content, 1);
        combined += adjusted + '\n\n';
      }
    }
  }

  // Write combined file
  const tempFile = '/tmp/combined.md';
  fs.writeFileSync(tempFile, combined);

  // Run Pandoc
  await pandoc({
    input: tempFile,
    output: config.outputPath,
    args: [
      '--defaults', config.pandocDefaults,
      '--metadata-file', config.metadataFile

}

PDF/A Compliance

Generate Archival PDF

# Using Pandoc with PDF/A output
pandoc input.md \
  -o output.pdf \
  --pdf-engine=xelatex \
  -V 'pdfa=1b' \
  --include-in-header=pdfa-header.tex

# pdfa-header.tex
\usepackage{hyperref}
\hypersetup{
    pdfstartview=,
    colorlinks=false,
    pdfpagelayout=SinglePage
}
\usepackage[a-1b]{pdfx}

Workflow

1. Collect sources - Gather Markdown files
2. Preprocess - Handle includes and variables
3. Convert - Transform Markdown to intermediate format
4. Apply template - Add styling and structure
5. Generate TOC - Build table of contents
6. Render PDF - Output final PDF
7. Optimize - Compress images and fonts
