Add language autocomplete for supported languages (#247)

mishushakov · claude · web-flow · commit 6d54054eb165 · 2026-04-16T13:58:50.000-07:00
* Add language autocomplete for js, ts, r, java, bash

Co-Authored-By: Claude Opus 4.6 &lt;noreply@anthropic.com&gt;

* Fix eslint ban-types error for string &amp; {}

Use NonNullable&lt;unknown&gt; instead of {} to satisfy @typescript-eslint/ban-types.

Co-Authored-By: Claude Opus 4.6 &lt;noreply@anthropic.com&gt;

* Simplify language type to plain string union

Co-Authored-By: Claude Opus 4.6 &lt;noreply@anthropic.com&gt;

* Use string &amp; {} with eslint-disable for language autocomplete

Co-Authored-By: Claude Opus 4.6 &lt;noreply@anthropic.com&gt;

* Format sandbox.ts with prettier

Co-Authored-By: Claude Opus 4.6 &lt;noreply@anthropic.com&gt;

* Use eslint-disable/enable block for ban-types on multiline type

Co-Authored-By: Claude Opus 4.6 &lt;noreply@anthropic.com&gt;

* Format Python language type annotations for ruff
