pub fn markdown() -> StringExpand description
PI.6: the whole plugin API as markdown, rendered from the canonical wit/
package.
Lives here rather than in the host because it is a rendering of the
CATALOG, and the catalog is this crate’s. That placement is what lets the
site’s reference page be generated by a test in this crate instead of only
by :export-plugin-api inside a running editor — a reference a developer
can only obtain by launching the editor is one they will not read.
