A Roc platform to work with files, commands, HTTP, TCP, command line arguments,...

👀 examples:

• latest main branch

📖 documentation:

• TBA -- roc docs not yet implemented in the new compiler

⚠️ IMPORTANT: This branch (migrate-zig-compiler) requires the new Roc compiler and roc_std_new to be at matching versions to avoid ABI layout mismatches.

This project uses pre-built Roc nightly releases from roc-lang/nightlies. The pinned nightly version is specified in Cargo.toml via the # roc-nightly: comment and roc_std_new rev.

The CI scripts automatically download the correct nightly based on this configuration. See CONTRIBUTING.md for how to update the Roc version.

This branch migrates basic-cli to the new Zig-based Roc compiler and RocOps ABI.

✅ Completed:

• All core modules (Cmd, File, Dir, Path, Env, Random, Sleep, Utc, Stdin/Stdout/Stderr)
• Single-variant tag union layout fix (RocSingleTagWrapper now correctly includes discriminant)
• Comprehensive testing and verification

Note: Single-variant tag unions (e.g., [PathErr(IOErr)]) are represented in the Roc ABI with a discriminant byte (always 0) even though there's only one variant. The RocSingleTagWrapper<T> type implements this standard Roc ABI layout. This type could potentially be upstreamed to roc_std_new for reuse across platforms.
