FAQPage Schema

How do I detect duplicate MoonBit code in MBT projects?▼

To detect duplicate MoonBit code, run similarity-mbt on your project to analyze MBT source files using AST-based similarity analysis and identify exact or near-duplicate functions across modules.

How does AST-based similarity analysis work for MoonBit refactoring?▼

AST-based similarity analysis parses MBT files into abstract syntax trees to compare structural patterns, enabling the detection of exact and near-duplicate code blocks that require refactoring.

Can I filter MoonBit code duplication results by threshold and minimum lines?▼

You can filter code duplication results by running similarity-mbt with optional arguments like --threshold and --min-lines to prioritize high-impact duplicates and surface actionable insights.

What is the best way to consolidate duplicate MBT functions across modules?▼

The best way to consolidate duplicate MBT functions is to analyze the categorized results from similarity-mbt and follow its concrete refactoring plan to extract shared logic and parameterize differences.

Does this static analysis tool work with any MoonBit project structure?▼

This static analysis tool applies to MoonBit projects containing MBT source files, specifically identifying refactoring opportunities and enforcing code quality across modules within those projects.
