Syntax highlighting and workspace navigation for Cosense/Scrapbox files. The language server is bundled, so no separate setup is required.

Features

  • Syntax highlighting, including embedded code blocks
  • Clickable page links, hash tags, and URLs
  • Page completion, link-status hover, definitions, references, and backlinks
  • Visual states for missing and ambiguous page links
  • Document outline for headings and code or table blocks
  • Cosense-aware NEST editing with Enter, Tab, Shift+Tab, and Backspace

Supported filename extensions are .sbx, .scrapbox, .cos, and .cosense.

Open a folder containing Cosense files. The extension starts automatically and requires no settings. VS Code 1.90 or newer is required.

Limitations

Workspace features resolve only files in the open workspace. Language-server features are suspended for documents over 2 MiB or lines over 16 KiB, while basic syntax highlighting remains available.
