 # ldiff — lexer-based diff for MoonBit code
 
-## GitHub commit playground
-
-The static Rabbita playground accepts either of these public GitHub URLs:
-
-```text
-https://github.com/{owner}/{repo}/commit/{sha}
-https://github.com/{owner}/{repo}/pull/{number}/changes/{sha}
-```
-
-Both forms compare the commit with its first parent (or an empty old side for
-a root commit). Every changed file receives a card in GitHub's order. Files
-whose old or new path ends in `.mbt` use ldiff's MoonBit-aware lexical diff;
-other valid UTF-8 text files use a plain line diff. The first 20 MoonBit diffs
-open automatically, while all other files load on demand.
-
-Each downloaded side is limited to 1 MiB and 20,000 lines. Invalid UTF-8,
-NUL-containing, binary, and over-limit content keeps its file card and shows
-an explanatory message instead of a rendered diff. The browser fetches
-anonymous GitHub REST and raw-content endpoints and never accepts, stores, or
-sends a personal access token. Anonymous GitHub API rate limits therefore
-apply.
-
-Submitting a GitHub URL updates the browser to a static-host-friendly share
-route:
-
-```text
-https://{playground-host}/{base}/#/owner/repo/commit/sha
-```
-
-Opening that URL restores and loads the same commit automatically. The result
-page also exposes the full URL in a read-only field with a one-click copy
-button. Hash routing keeps shared links working on GitHub Pages without a
-server-side rewrite rule.
-
-Run the live development server from the Warren app directory:
-
-```sh
-cd playground
-warren dev --direct
-```
-
-Create the release site with:
-
-```sh
-cd playground
-warren build
-```
-
-
-The playground also has Chromium end-to-end tests. They build the MoonBit JS
-release into a temporary directory, serve it with the static assets in
-`playground/public`, and mock every GitHub API and raw-content request. Install
-the pinned Node dependencies and Playwright browser once, then run the suite:
-
-```sh
-cd playground
-npm ci
-npx playwright install chromium
-npm run test:e2e
-```
-
-On a machine that is missing Chromium system libraries, use
-`npx playwright install --with-deps chromium` instead. For an interactive
-Playwright session, run `npm run test:e2e:ui`.
