codegen: InputOutput Error

[jcalabro]

Zig Version

0.14.0-dev.2577+271452d22

ZLS Version

0.14.0-dev (specifically 9fc45ca)

Client / Code Editor / Extensions

helix 25.1

Steps to Reproduce and Observed Behavior

Hi all, I'm getting an error unable to codegen: InputOutput on this line of the debugger. This just started happening the other day because I ran 0.13.0 for a long time, and just upgraded both zig and zls.

Not 100% if this is a zig or a zls bug, but the program builds and runs just fine, and countNumberOfDigits isn't dead code; it's used all over this file.

Expected Behavior

I expect zls to be able to handle the linked zig file and give me appropriate suggestions without giving me warnings or errors.

Relevant log output

You did not include the zig file you are refering to. Make sure that your issue includes all the necessary information to reproduce the observed behaviour.

Whoops, meant to link to it, sorry. It's here: https://github.com/jcalabro/uscope/blob/bab9a9396e9a74cb10af39d45079e7897d0437d4/src/gui/views/Primary.zig#L698

[Techatrix]

Could you elaborate further? Your issue description is a mystery to me. Where are you seeing this error? What exactly are you doing to get this error? How is this related to the countNumberOfDigit function?

[jcalabro]

All I did was open that file in helix. The reason I pointed that function out is that it was the one that was erroring with the message unable to codegen: InputOutput on the line of the function definition of countNumberOfDigits. Not sure I can elaborate further.

However, I just tried to repro and I can't so I guess we should close.

[Techatrix]

Oh so you are getting that error displayed as a diagnostic in your editor. This is what I was wondering about. The source of such an error would most likely be Build On Save. Did you enable this feature by chance?

[jcalabro]

I did enable that at some point, yes! https://github.com/jcalabro/dotfiles/blob/main/fedora/zls.json

This only started happening the other day after updating from zig 0.13.0 -> 0.14.0-dev.2577+271452d22

Still not sure how to repro though...tried from multiple machines but couldn't get it to crop back up

[jcalabro]

Probably a zig compiler issue rather than zls. I just got a zig build error when invoking the compiler (not zls):

src/safe.zig:109:5: error: unable to codegen: InputOutput
