75-80: Good encapsulation of unsafe operation.The
handle_runfunction properly isolates the unsafecompile_and_runcall. Consider enhancing error handling if the underlyingcompile_and_runfunction could be modified to returnResultfor better error propagation.

Cargo.toml (1)
3-3: Version update looks good.The nightly build version format is appropriate for pre-release software. Note that the date "2025-07-16" appears to be in the future, which may be intentional for nightly builds.
.mailmap (1)
1-5: Excellent consolidation of author identities.The .mailmap update properly consolidates multiple email addresses and name variations under a single canonical identity, which will ensure consistent author attribution across the codebase.
test/test33.wave (1)
28-28: Good syntax fix.Adding the missing semicolon corrects the syntax error and aligns with the language's requirements.
src/main.rs (7)
1-2: Good import additions.The new imports for
fmtandprocessmodules, along withPath, are appropriate for the enhanced error handling and CLI functionality.
7-15: Well-designed error enum.The
CliErrorenum effectively covers the main CLI error scenarios with clear, descriptive variants. TheMissingArgumentvariant with structured fields for command and expected argument is particularly well thought out.
17-37: Excellent error message implementation.The
Displayimplementation provides clear, user-friendly error messages with consistent colored formatting. Each error variant is handled appropriately with descriptive messages that guide users on what went wrong.
39-45: Excellent main function structure.The refactored main function follows Rust best practices by delegating to a fallible
run()function and properly handling errors with informative messages and usage instructions.
47-73: Excellent refactoring of CLI argument parsing.The iterator-based approach is more efficient than the previous vector collection method. The explicit error handling with the
?operator and proper command matching significantly improves the robustness of the CLI.
82-86: Clean usage message function.The
print_usagefunction provides a clear, consistently formatted usage message that complements the error handling.
88-101: Comprehensive and well-formatted help message.The
print_helpfunction provides excellent user guidance with a clear description, usage information, and detailed command explanations. The consistent color scheme enhances readability.
I repurposed the CLI to look good.
