2026-09-04Split the page shell out of the repository layoutJoe Mou
layout.eta was two things at once: the HTML shell every page needs and the repository chrome around it. owner.eta, being the one page that is not about a repository, could use neither and carried its own copy of the shell, which had drifted -- its footer named no build commit and did not link to the original page on GitHub. The shell moves to views/layouts/base.eta, taking its title and any deferred scripts as layout data, and the chrome to views/layouts/repo.eta, a layout over it that adds the clone commands, nav, search box, and the "/" shortcut that focuses it. Repository pages point at repo.eta and render as before; owner.eta uses base.eta directly and so gains the footer it was missing. Templates now live in more than one directory, so scripts/build.ts walks views/ recursively and keys each template by its path underneath it. Names crossing a directory are written from the views root ("/layouts/base.eta"), the one form both Eta's filesystem resolver and the precompiled resolver in worker.ts agree on; siblings stay relative.

2026-09-03Handle route errors in middlewareJoe Mou
Every page route wrapped its scrape in tryRender, which awaited the promise, rendered the template on success, and turned a failure into a redirect or an error page. Hono's onError does that mapping for all of them at once, so handlers now await their scrape inline and both wrappers are gone. Fragments under /api/ still fail as an empty body rather than a page; onError checks for them first, since a fragment turns a redirect into a 404 instead of following it. RedirectError becomes an abstract base with InternalRedirectError and ExternalRedirectError under it, so the handler dispatches on the type instead of sniffing the location for an https:// prefix. One behavior change: a thrown value that is not an Error no longer renders error.eta, because Hono only routes Error instances to onError.

2026-09-03Clean up renderer, redirects, and build commitJoe Mou
2026-09-03Render repository wikisJoe Mou
Wikis are one of the last parts of GitHub still served as plain Rails HTML, with no embedded JSON to read, so this scrapes the markup: a page and any older revision of it, the _Sidebar and _Footer a wiki can define, and the page index. Every page is already in the sidebar of every page, since the "Show N more pages" button only unhides the rest, so linking the whole wiki costs no second request. Routes mirror GitHub's and resolve in its order, so an underscore name reserved for its own actions (_pages, _history, _new, _edit) can never be mistaken for a page; the ones we don't serve fall through to the usual redirect. A slug reaches us decoded and has to be encoded again rather than interpolated the way a ref is, or a page named C# would truncate at the fragment.

2026-08-27Display PDF blobsJoe Mou
GitHub renders a PDF with a viewer of its own and so ships no content for one, leaving the blob view with nothing to show. Its raw bytes come as application/octet-stream, which browsers download rather than display, so serve them from a new embed route that retypes them and point an <object> at that.

2026-08-12Use an HTTP redirect for same-origin requestsJoe Mou
The meta refresh page renders as a broken image when the request came from an <img> on one of our own pages. Such requests are already past the redirect-loop hazard the refresh works around, so send them a real redirect instead.
2026-08-11Read the About box and latest release from JSONJoe Mou
GitHub rebuilt the repository sidebar, so the selectors parseRepoInfo used matched nothing and the About box rendered empty. Everything but the latest release is in the page's embedded payload as sidebarAbout; the latest release is only in the _sidebar JSON already fetched for languages, so it arrives with that fragment and is moved beside the release count.
2026-08-11Keep the ref picker on the current view and pathJoe Mou
2026-08-11Redirect to GitHub with a meta refreshJoe Mou
A browser extension redirects github.com to cgithub with declarative net requests. Its rules match our HTTP redirects back to github.com too, so those bounce straight back here and loop forever. A meta refresh makes cgithub the initiator origin instead, which the extension's rules can exclude, and its delay leaves a page the user can stop on.

2026-08-11Show the build's commit in the page footerJoe Mou
Workers can't shell out at request time, so the commit has to be baked in before wrangler bundles the sources. compile-views.ts grows a second job and becomes scripts/build.ts: alongside the precompiled views it writes src/commit.generated.ts with `git describe --tags --always --dirty`, which yields a bare short hash until the repo is tagged and marks builds made from an unclean working copy.

2026-08-11Link repo header and add a "View original" linkJoe Mou
The owner/name header in the layout now links to the owner page and the repository root. tryRender passes the request's path and query through as githubUrl — our URLs mirror GitHub's, so the same path is the page we scraped — and the footer links there with rel="noreferrer", matching the no-referrer policy used on redirects to github.com.

2026-08-11Add language percentages to repo pagesJoe Mou
GitHub no longer server-renders the repository sidebar; its React UI lazily fetches /:owner/:repo/_sidebar as JSON, which carries the language breakdown (name, percentage, color). getGitHubLanguages() uses that endpoint, and a new /api/:owner/:repo/languages fragment route renders the bar and legend the same way refs and latest-commit already work, so repo page loads still cost a single scrape. The latest-commit placeholder loader in refs.js is generalized over .placeholder[data-src] so both placeholders share it. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
2026-07-22Add async branch/tag dropdown and latest-commit barJoe Mou
Adds two lazily-fetched UI pieces to match vanilla GitHub while keeping initial page loads plain server-rendered HTML: a branch/tag selector (native <dialog>, CSS anchor-positioned to its button, light-dismissed via closedby="any") and a latest-commit bar above the file listing. Both are populated by new /api/:owner/:repo/refs/:type and /api/:owner/:repo/latest-commit/:branch/:path routes; the latter calls GitHub's own /latest-commit JSON endpoint (the same one the React UI uses) rather than scraping the full commit history page.
2026-07-15Add Cloudflare Workers deployment targetJoe Mou
Split routes into a shared createApp() (src/app.ts) used by both the Node entry (src/index.ts) and a new Workers entry (src/worker.ts). Workers disallow runtime code generation, so scripts/compile-views.ts precompiles the Eta templates into src/views.generated.ts and rendering switches from renderAsync to the sync render. Static files move to public/static so Workers Static Assets can serve them; the Node build and serveStatic root are updated to match. Deploy with pnpm run deploy:cf, local dev with pnpm run dev:cf.
