Code Review

This pull request adds a new configuration file registry/codon.toml for the Codon Python compiler, defining its backends, description, supported operating systems, and a basic version test command. I have no feedback to provide.

Greptile Summary

Adds a registry entry for codon, a high-performance Python compiler, using the github:exaloop/codon backend. The entry correctly restricts supported platforms to Linux and macOS (codon has no Windows releases), and the {{version}} test expectation is confirmed accurate by the developer's verification in a prior thread.

Confidence Score: 5/5

Safe to merge — minimal, well-formed registry addition with no logic or security concerns.

Single-file change adding a new tool registry entry. Format matches existing patterns, OS restriction is appropriate, and the version test format was already verified against the live binary. No issues found.

No files require special attention.

registry/codon.toml	New registry entry for the codon Python compiler; backend, description, OS filter, and version test all look correct.

+backends = ["github:exaloop/codon"]
+description = "A high-performance, zero-overhead, extensible Python compiler with built-in NumPy support"
+os = ["linux", "macos"]
+test = { cmd = "codon --version", expected = "{{version}}" }


Potential version prefix mismatch in test

The expected = "{{version}}" template expands to the bare version number (e.g. 0.19.6), but codon's CLI appears to emit version strings with a v prefix — the JIT banner outputs Codon JIT v0.19.0, and release tags are in the form v0.19.x. If codon --version outputs v0.19.6 (or codon v0.19.6), the test will always fail. Other tools with the same pattern in this registry (e.g. age.toml, agebox.toml) use expected = "v{{version}}" for exactly this reason. Worth verifying against the actual binary output and adjusting if needed.

❯ mise exec github:exaloop/[email protected] -- codon --version 0.19.6
