repo-to-pdf

repo-to-pdf

Consolidated, public-facing PDF of a repository's documentation. Single-document output suitable for sharing, archiving, or publishing.

Inputs

• path (optional): repo path; defaults to cwd.
• title (optional): override the derived title.
• subtitle (optional): tagline shown under the title.
• output (optional): output PDF path. Default: ./<slug>.pdf.
• license (optional): overrides config default.
• banner (optional): path to a banner image; overrides scan result. Pass "none" to disable.
• no-banner (optional flag): force-disable banner even if one exists in the repo.

Procedure

1. Load manifest

If /tmp/repo-to-docs/<slug>/manifest.json is missing or the user passed --force, invoke the repo-scan skill first. Otherwise read the existing manifest.

2. Load config

Read ~/.config/repo-to-docs/config.json. If missing, use these defaults:

{
  "author_name": "",
  "author_url": "",
  "default_license": "MIT",
  "generate_banner_if_missing": false,
  "typst_footer_defaults": {
    "show_page_numbers": true,
    "show_repo_url": true,
    "show_license": true,
    "show_author": true
  }
}

3. Resolve banner

• If banner argument is a path, use it.
• Else if manifest has an image with kind: banner, use it.
• Else if generate_banner_if_missing is true and not disabled by flag, call the nano-tech-diagrams MCP text_to_image tool with:
  • prompt: "Technical documentation banner for '{title}' — {summary}. Clean minimalist style, suitable for PDF cover."
  • save to /tmp/repo-to-docs/<slug>/banner.png
• Else leave unset (no banner).

4. Assemble Typst document

Create scratch dir /tmp/repo-to-docs/<slug>/build/, copy in shared/styles.typ from the plugin.

Write main.typ:

#import "styles.typ": doc-base, ai-disclosure-block

#show: doc-base.with(
  title: "{{title}}",
  subtitle: {{subtitle_or_none}},
  author: "{{author}}",
  date: datetime.today(),
  repo-url: {{repo_url_or_none}},
  license: "{{license}}",
  show-page-numbers: {{show_page_numbers}},
  show-license: {{show_license}},
  show-repo-url: {{show_repo_url}},
  show-author: {{show_author}},
  banner-path: {{banner_or_none}},
  show-toc: true,
  toc-depth: 2,
)

// Body — concatenated from text_sources in manifest order.
// Each markdown source becomes a level-1 section; raw paragraphs pass through.
// Images referenced in markdown are copied in and rendered at their reference point.

Convert each markdown source to Typst (pandoc markdown -> typst, or a simple transform for headings, paragraphs, lists, code, images). Rewrite image paths to the build dir. Copy referenced images into the build dir. Images not referenced inline are appended at the end of their source's section.

5. Compile

/usr/local/bin/typst compile /tmp/repo-to-docs/<slug>/build/main.typ <output>

Fall back to typst on PATH if the absolute path is missing.

6. Report

• Output path
• Page count (via pdfinfo if available)
• Which banner was used (existing / generated / none)
