nandi (Jan 21 2026 at 00:43): nandi (Jan 21 2026 at 00:43):roc goes through setupSharedMemoryWithModuleEnv and explicitly compiles sibling modules before app canonicalization, based on imports extracted from the app AST./home/nandi/code/roc/src/cli/main.zig (see the section starting with “Compile sibling .roc files BEFORE app canonicalization.”)roc build uses compileAndSerializeModulesForEmbedding, which only compiles platform modules + app, and does not compile app sibling modules./home/nandi/code/roc/src/cli/main.zig inside compileAndSerializeModulesForEmbedding. Luke Boswell (Jan 21 2026 at 06:18):Is this a question or bug report?
Luke Boswell (Jan 21 2026 at 06:19):Have you observed some behaviour that isn't right?
nandi (Jan 21 2026 at 06:37):Is it a bug that roc build doesnt compile sibling modules?
Luke Boswell (Jan 21 2026 at 06:46):I don't understand what you mean by doesn't compile sibling modules.
Like if I have an app, with an import Foo in it -- you can't use Foo with roc build app.roc but you can with roc app.roc?
nandi (Jan 21 2026 at 06:53):It has to be in platform folder in roc build
nandi (Jan 21 2026 at 06:54):Which kinda breaks for modules that aren't in platforms
Luke Boswell (Jan 22 2026 at 22:02):I've reproduced this... should be able to fix it soon
Luke Boswell (Jan 22 2026 at 22:58):ok fixed it... but going to take a side quest to refactor things and hopefully eliminate this kind of bug from happening again
nandi (Jan 22 2026 at 23:02):what do you mean "this kind of bug"?
Luke Boswell (Jan 22 2026 at 23:11):Where there are different code paths roc check roc test roc build etc doing the same thing in different ways
Luke Boswell (Jan 22 2026 at 23:12):Just refactor the common parts into helpers and keep things DRY
Rick Hull (Jan 22 2026 at 23:32):I had noticed some different behavior with roc build that was unexpected but assumed I was Doing It Wrong. i think i hit this, though
