Question 1

How do I run unconvert on a Go module?

Accepted Answer

Install it with 'go install github.com/mdempsky/unconvert@latest', then run 'unconvert ./...' from your module's root directory to analyze all packages. Use flags like -apply to auto-fix or -v for detailed output.

Question 2

unconvert vs staticcheck for Go code quality?

Accepted Answer

unconvert specializes in detecting unnecessary type conversions, while staticcheck offers a broader range of checks including bugs, performance issues, and style. Use unconvert as a supplement for conversion-specific cleanup, not a replacement for comprehensive linters.

Question 3

Does unconvert work with Go generics from version 1.18?

Accepted Answer

The README doesn't specify, but as a static analysis tool, it may have limitations with generics due to type inference complexities. Check the GitHub issues or updates for compatibility, as older versions might not fully support new Go features.

Question 4

Can I integrate unconvert into a CI/CD pipeline?

Accepted Answer

Yes, run unconvert as part of your build script to flag or fix conversions. Use the -apply flag cautiously in CI to avoid automatic changes; instead, use it to generate reports or fail builds on detected issues for manual review.

Question 5

How to ignore certain conversions with unconvert?

Accepted Answer

unconvert doesn't have built-in ignore mechanisms; you might need to manually review output or use external tools to filter results. For automated workflows, consider post-processing the output or contributing to the project for ignore feature requests.

Question 6

What are common false positives with unconvert?

Accepted Answer

False positives can occur in code with interface types, type aliases, or architecture-specific files where conversions are necessary under certain GOOS/GOARCH combos. The -all flag helps mitigate this by checking all environments, but manual inspection is still advised.
