Details

A static analysis tool for Go that detects iota usage without explicit type specification.

iotyper is a golangci-lint plugin that ensures iota constants have explicit types to improve code clarity and type safety.

iotyper reports when iota is used in const declarations without an explicit type:

// ❌ Bad: will be flagged
const (
    StatusPending = iota  // Error: iota used without type specification
    StatusActive
    StatusClosed
)

Add an explicit type to your iota declaration:

// ✅ Good: type explicitly specified
const (
    StatusPending int = iota
    StatusActive
    StatusClosed
)

You can suppress the linter using //nolint comments:

const (
    Value1 = iota  //nolint:iotyper
    Value2 = iota  //nolint:all
)
