We enabled [`CompletionListisIncomplete`] in our LSP server a while back in order to have more of a say in how we rank and filter completions. When it isn't set, the client tends to ask for completions less frequently and will instead do its own filtering. But... we did not enable it for the playground. Which I guess didn't result in anything noticeably bad until we started limiting completions to 1,000 suggestions. This meant that if the _initial_ completion response didn't include the ultimate desired answer, then it would never show up in the results until the client requested completions again. This in turn led to some very poor completions in some cases. This all gets fixed by simply enabling `isIncomplete` for Monaco. Fixes astral-sh/ty#2340 [`CompletionList::isIncomplete`](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#completionList)
playground
In-browser playground for Ruff. Available https://play.ruff.rs/.
Getting started
Install the NPM dependencies with npm ci --ignore-scripts, and run the development server with
npm start --workspace ruff-playground or npm start --workspace ty-playground.
You may need to restart the server after making changes to Ruff or ty to re-build the WASM
module.
To run the datastore, which is based
on Workers KV,
install the Wrangler CLI,
then run npx wrangler dev --local from the ./playground/api directory. Note that the datastore
is
only required to generate shareable URLs for code snippets. The development datastore does not
require Cloudflare authentication or login, but in turn only persists data locally.
Architecture
The playground is implemented as a single-page React application powered by Vite, with the editor experience itself powered by Monaco.
The playground stores state in localStorage, but supports persisting code snippets to
a persistent datastore based
on Workers KV
and exposed via
a Cloudflare Worker.
The playground design is originally based on Tailwind Play, with additional inspiration from the Biome Playground.
Known issues
Stack overflows
If you see stack overflows in the playground, build the WASM module in release mode:
npm run --workspace ty-playground build:wasm.
