CLAUDE.md - Guidelines for Fossa CLI

Build Commands

• Haskell: cabal build, make build-cli
• Rust: cargo build --release
• Full Build: make build (builds both)
• Unit Tests (Haskell): cabal test unit-tests or make test-cabal ARGS="TestName"
• Unit Tests (Rust): cargo test or make test-cargo
• Integration Tests: make integration-test ARGS="TestName"
• Format Code: make fmt (runs both formatters)
• Lint Code: make lint (runs both linters)
• Analyze Project: make analyze

Code Quality Standards

• Compiler warnings should be treated as errors and fixed, not ignored
• Linter warnings should be treated as errors and fixed, not ignored
• All tests must pass before submitting code
• Code should be thoroughly tested with appropriate unit tests

Code Style Guidelines - Haskell

• GHC Version: 9.8
• Formatting: fourmolu with 2 spaces, leading commas
• Imports: Use explicit imports, qualified with full names
• Types: Prefer newtype, use Text instead of String
• Functions: Avoid partial functions, list comprehensions, match guards
• Error handling: Never use error or undefined

Code Style Guidelines - Rust

• Format with rustfmt via cargo fmt
• Lint with Clippy via cargo clippy
• Follow standard Rust idioms including error handling
• Use the Rust embedded tools within the Haskell code via the extlib directory
