When a hosting service (like Cloudflare Pages) strips .html from URLs, the TOC sidebar highlighting breaks because the current page URL no longer matches the link hrefs which contain .html. This adds a normalizeUrl() function that strips .html suffixes before comparing, so the TOC correctly highlights the active page regardless of whether the host uses pretty URLs. Fixes rust-lang#3034

Thanks for the PR! I've decided to go with a slightly simpler solution in #3028. Let me know if there is something it doesn't cover. |

Problem
When a hosting service (like Cloudflare Pages) strips
.htmlfrom URLs ("pretty URLs"), the TOC sidebar highlighting breaks. The current page URL no longer ends in.html, but the TOC link hrefs still do, so the comparisonlink.href === current_pagenever matches.Fix
Added a
normalizeUrl()function in the TOC initialization JS that strips.htmlsuffixes (and normalizes/index.htmlto/) before comparing. The original exact comparison is kept as a fast path, with the normalized comparison as a fallback.This means the TOC works correctly whether the host serves
.htmlURLs or pretty URLs.Test
Added
toc_js_normalizes_urls_for_pretty_urlstest that verifies the generatedtoc.jscontains the URL normalization logic.Full test suite passes on macOS ARM (Apple Silicon): 119 tests, 0 failures.
