Tsoding Daily

A live coding session implementing a custom testing tool called 'btest' in Rust for a B programming language compiler. The developer creates a matrix-based testing system that runs tests across multiple target platforms (x86-64 Linux, Windows, ARM64, UXN virtual machine), collecting build and runtime status for each combination. Key features include colored terminal output for test results, factoring out platform-specific runners into separate modules, and converting IR from a compilation target into a debugging flag. The session demonstrates practical compiler development techniques, cross-platform testing strategies, and Rust programming patterns for systems-level tools.
