A VS Code extension that shows bun run and bun test output on the line that logged it

Hi Bun folks. This is Inline Logs, a free VS Code extension I made that works with Bun.

The way it hooks in: VS Code's terminal gets a BUN_OPTIONS value with --preload pointing at a small script, written in a form every bun command accepts. So bun run and bun test pick it up with nothing added to your project. The script wraps console, Bun's http and https calls and the built-in WebSocket, and sends each entry to the extension on 127.0.0.1. The extension puts the value at the end of the source line that made it.

With bun test, a log inside a test lands on that test's line, so you can see what a failing test printed without scrolling the terminal. Bun's stack frames for top-level code have no column, and those map to the right line too. Programs built with bun build --compile are left alone, so a compiled CLI you run in the same terminal does not report into your editor.

GPL, no account, no paid tier, and everything stays on your machine.

I would love to hear from anyone running it on a bigger Bun project, especially if something lands on the wrong line.
