Ameba::Rule::Lint::EnumMemberNameConflict

Inherits YAML::Serializable < Ameba::Rule::Base < Ameba::Config::RuleConfig < Reference < Object

A rule that reports conflicting enum member names.

Since Crystal will parse enum member names using String#camelcase and String#downcase, it is important to ensure that each member has a name that stays unique after the transformation.

enum Foo
  Bar
  BAR
end

Foo.parse("bar") # => Foo::Bar
Foo.parse("Bar") # => Foo::Bar
Foo.parse("BAR") # => Foo::Bar

YAML configuration example:

Lint/EnumMemberNameConflict:
  Enabled: true

Constants

MSG = "Enum member name conflict detected"
