However, I can't seem to run build. I have Zig 0.14.1 installed, after running zig build roc, and doing ./roc build test.roc, I get hit with the build not implemented

Cool :)
The build subcommand is not yet implemented for the new (zig) compiler. roc check file.roc is partially implemented. Perhaps we have some roc run file.roc things working as well, is run already hooked up with the interpreter @Luke Boswell?
Luke Boswell (Aug 22 2025 at 22:40):Yeah, we a have other subcommands implemented but not build yet. I think that will be the last to come online.
You can see how to use the test platform here https://github.com/roc-lang/roc/tree/main/test/str
Luke Boswell (Aug 22 2025 at 22:40):zig build -Dllvm
# Run (ignore cached files)
./zig-out/bin/roc --no-cache test/str/app.roc
note - In my latest PR I was going to remove the -Dllvm flag and have that built by default to simplify working with Roc for new contributors.
Luke Boswell (Aug 22 2025 at 22:42):In this PR comments I show an example of how you can use roc test https://github.com/roc-lang/roc/pull/8211
Luke Boswell (Aug 22 2025 at 22:42):roc format and roc check work as you would expect I believe.
Luke Boswell (Aug 22 2025 at 22:43):roc bundle and roc unbundle are new and not that useful yet... but working for managing roc packages
Luke Boswell (Aug 22 2025 at 22:44):@EnDeRBeaT if you would like help getting started with anything let me know. Always happy to jump on a call with new contributors :smiley:
Luke Boswell (Aug 22 2025 at 22:48):The roc repl is ready to be implemented. We could start with a very simple cli interface.
Alternatively we've thrown the idea around of using a tui library for the roc cli... that's a bigger project and would need much more design work and discussion but also would be heaps of fun to work on.
Luke Boswell (Aug 22 2025 at 23:22):Also helpful for new contributors is the Playground https://roc-lang.github.io/roc-playground/ which shows source code and the intermediate representation as it progresses through each compiler stage, and a REPL for playing with expressions.
