feat(yasgui): show IRI info when hovering an IRI in the editor - #234
Merged

Conversation
Hovering an IRI or prefixed name in the query editor shows a tooltip with its label, description, type and (for properties) domain and range, fetched with a small background query on the tab's endpoint, cached per endpoint and IRI, with a LOV lookup when the endpoint doesn't describe it. Can be switched off in Settings > Editor or with the iriHover option. Yasqe gets the iriHover / iriHoverDelay options and getIriAt(), which the Ctrl+click URI explorer now uses too. Closes #196

Before: to find out what
era:solNatureor an opaque instance IRI in a query means, you had to Ctrl+click it, which replaces the results view.After: resting the mouse on an IRI or prefixed name in the editor shows a tooltip with its label, full IRI, description, type and (for properties) domain and range. It reminds you of Ctrl+click / Ctrl+Shift+click, and can be switched off in Settings → Editor.
Closes #196
How
iriHover/iriHoverDelayoptions, using CodeMirror 6'shoverTooltip, and agetIriAt(pos)method that finds the IRI or expanded prefixed name at a position (ignoring variables, literals and blank nodes). The Ctrl+click URI explorer inTab.tsnow usesgetIriAtinstead of its own token parsing.IriHoverInfo.ts): aSELECT ?p ?oonrdfs:label,skos:prefLabel,rdfs:comment,skos:definition,rdf:type,rdfs:domain,rdfs:rangeviatab.runBackgroundQuery(tab auth and request settings), 10 s timeout, cached per endpoint + IRI (failures are retried on the next hover). Label and comment prefer the browser languages, then English, then untagged. Types are shortened with the query prefixes plus a few common ones.GRAPH ?g). Not verified against the live LOV endpoint, because the cloud environment can't reach it; it fails silently. It can be turned off withiriHoverLovFallback: false.iriHover(default true) andiriHoverLovFallback(default true), user setting in Settings → Editor, documented in the user and developer guides, plus a changeset.Tests:
test/iri-hover-browser.ts(7 Puppeteer tests against a mocked endpoint: tooltip content, caching, LOV fallback, variables, setting off,getIriAtedge cases, Ctrl+click still works). The full Puppeteer suite and unit tests pass locally. Light and dark screenshots are in the project thread.Generated by Claude Code
