treemd

treemd shows a markdown document as a navigable outline next to its rendered
content, with syntax highlighting, tables, task lists, images and Mermaid
diagrams. A jq-like query language extracts headings, links, code blocks and
other elements for scripts.

Examples

treemd can open documents in your home directory and from URLs. To also open
