Kilian Vounckx (Jul 22 2026 at 19:08): Kilian Vounckx (Jul 22 2026 at 19:08):I'm not sure if this is already answered somewhere, but I'm trying to use basic-cli with the new zig compiler. I'm using the latest main branch for both roc and basic-cli. I get this error in basic-cli however:
┌────────────────┐
│ DOES NOT EXIST ├─ U32.shift_left_by does not exist. ────────────────────────────────────────────────────────────────────────────────────────────────────────────────────┐
└┬───────────────┘ │

└────────────────────────────────────────────────────────────────────── /Users/kilian/Documents/Personal/projects/roc/habba/vendored/basic-cli/platform/OsStr.roc:132:10 ┘
U32 is in scope, but it has no associated shift_left_by.
(And a bunch of other very similar ones)
Kilian Vounckx (Jul 22 2026 at 19:08):Is this a known issue? Should I just be waiting for a while, while basic-cli gets updated properly for the new compiler?
Niclas Ahden (Jul 22 2026 at 19:31):Yes, I've PR:d a fix and it'll probably work with tomorrow's nightly :octopus:
If you're an addict like me, here's a temporary fix: https://github.com/niclas-ahden/basic-cli/releases/tag/0.22.1
Kilian Vounckx (Jul 22 2026 at 19:33):Cool! Trying it now
Richard Feldman (Jul 22 2026 at 21:19):sorry, I just did a pass updating some Num builtins and this was affected!
Austin Clements (Jul 23 2026 at 19:30):One comment on the new bitwise shift name shl_wrap my initial assumption was that this is for the shifted-out bits to wrap around the front (aka rotate I guess). I see that the docs clarify it and I can’t say I have a better name in mind, but is there a reason for the modulo behavior on the shift amount rather than just clamping the max shift to the full integer width?

That PR is merged now and a fresh nightly is out.
