Generate project documentation

Related guide: project-documentation.

Generate project documentation writes a folder of static HTML, CSS, JavaScript, and SVG for the current Hop project. Open index.html in a browser — no server.

Name the action, then set:

Target folder — where the site is written (variables supported, default '${PROJECT_HOME}'/work/documentation)
Source folder — optional scan root; empty uses '${PROJECT_HOME}'
Scope — project files only, or also environment variables (secrets redacted)
CSS theme — default, compact, or high-contrast
Include parameters, Markdown notes, metadata, catalog records, lineage, and dark-theme SVG copies

The same generator is available as hop project-doc and Tools → Generate project documentation…. From the Tools menu, Hop shows a cancelable progress dialog while the site is generated (including on Hop Web). Desktop opens index.html in the system browser; Hop Web opens it in the File explorer perspective with stylesheets and links served through a RAP handler.

The site’s left-hand navigation is a tree by object type, then project folder (files), parent model (tables), metadata type and virtual path, or catalog namespace. Type groups start collapsed; siblings stay visible; expanded folders are remembered. The header has a breadcrumb, search on the right, and a theme combo. Items sort alphabetically, case-insensitive.
