Table of Contents not being created #132
Description
I’m using Crowbook 0.16.1 to generate a PDF from a single Markdown file with the following YAML header:
title: "Mein Buchtitel"
author: "Max Mustermann"
lang: de
output.pdf: MeinBuchNeu.pdf
My chapters and sections are formatted like this:
Deutsche Tugenden - Eine SWOT-Analyse für Startups
Was können wir gut und was prägt uns?
Die Rolle der Präzision in der deutschen Kultur
…and so on, with each heading separated by a blank line and text below.
Command:
crowbook -s Neu.md --to pdf --set tex.class book rendering.inline_toc true rendering.num_depth 2
Result:
The PDF is generated, the content and headings are there, but the Table of Contents (TOC) page is always empty (just the heading, no entries).
⸻
What I’ve tried:
• Different combinations of YAML header vs. CLI options.
• Both rendering.inline_toc: true in YAML and as --set.
• Changing the order of the YAML header fields.
• Using both -s and omitting it.
• Removing or keeping all blank lines, comments, etc.
• Ensuring headings are all properly formatted as #, ##, ###.
• I have LaTeX (xelatex) working; PDF is generated without other errors.
⸻
Expected:
A TOC page that lists all top-level and section headings (at least those marked with # and ##).
Actual:
The TOC page is empty.
⸻
Questions:
• Is this a bug, or am I missing a required YAML or CLI option?
• Does Crowbook require a certain minimal structure (e.g., multiple files or explicit chapters) for TOC to work in single-file mode?
• Has anyone gotten a single-file, YAML-header-based workflow to produce a working TOC in PDF recently? If yes, can you share your exact working example (Markdown and command)?
