Read the HTML report

The HTML report is owlcompare's flagship deliverable: a single self-contained file you can open offline, attach to an email, or commit to a pull request. It presents the same diff as the terminal view, but organized for unhurried review — breaking changes first, everything else grouped and collapsible. This page will be a guided tour of every part of it. Generate one with owlcompare diff a.ttl b.ttl --format html --out report.html, or open the live example.

The outline below anchors the scope; the full annotated tour is coming.

What this page will cover

• The header and status badge — the at-a-glance "is this safe to merge?" signal.
• The sticky summary strip — counts by severity, always visible as you scroll.
• The sections — Renames → Breaking → Other → Unexplained Layer 0, and why they're ordered that way.
• Anatomy of a change card — the severity stripe, the summary line, the "why breaking" refinement note, and the collapsible details.
• The toolbar — section collapse, the light/dark/auto theme cycle, the copy-link button, and the JSON download.
• Working offline — why there are no external resources, and what that means for sharing.
• Performance — how the report stays responsive at thousands of changes.
