embedpaper 0.1.0

Embed full PDF papers into a Typst document, preserving selectable text and links.

embedpaper

Embed full PDF papers into a Typst document, preserving selectable text and links.

Typst 0.15's native image() can embed PDF pages full-width with selectable text, but it drops link annotations. embedpaper restores them: a Typst function places each page and records where it landed, and a small CLI re-creates the source PDF's citation, cross-reference, and URI links on the compiled output.

Install

uvx embedpaper --help

Requires uv and the Typst CLI on your PATH.

Usage

1. Import embedpaper.typ and call it inside a page for each PDF you want to embed:

   #import "embedpaper.typ": embedpaper
   
   #page[
     #embedpaper("papers/example.pdf", 12)
   ]
   

   pages is the PDF's page count (Typst can't query it, so pass it explicitly). Pass width: to scale the paper against the page width (default 100%).

2. Compile, then run embedpaper to restore the links:

   typst compile document.typ
   uvx embedpaper document.typ
   

   This reads the placement metadata Typst embedded during compilation and incrementally saves document.pdf with each source link remapped onto its embedded page.

3. Optionally, verify the result:

   uvx embedpaper document.typ --audit
   

   The audit re-derives where every link should point from the source PDFs and checks the compiled document against it — link count parity, correct destinations, and "Figure N" / "Table N" cross-references — exiting non-zero on any mismatch.

How it works

• embedpaper.typ places each source page as an image and emits <__paperlink> metadata (filename, source page, output page, and placement rectangle) for every embedded page.
• embedpaper embed queries that metadata with typst query, then uses PyMuPDF to copy each source page's links onto the matching output page, scaling coordinates and remapping internal destinations to their new page.
