@topecongiro I fixed it in arch with eshell. I’m running it in a vm, but it should be the same. Please test it again. Now instead of panicking with failed to emit error, it panics on something else. I don’t know if that’s a bug though. Files with syntax errors on the other hand, error as expected.

Ideally, this would still format my rust code, skip whatever fancy colors or whatever are being attempted, and exit cleanly.
