class Ameba::Rule::Style::PredicateName

Overview

A rule that disallows tautological predicate names, meaning those that start with the prefix has_ or the prefix is_. Ignores if the alternative isn't valid Crystal code (e.g. is_404?).

Favour these:

def valid?(x)
end

def picture?(x)
end

Over these:

def is_valid?(x)
end

def has_picture?(x)
end

YAML configuration example:

Style/PredicateName:
  Enabled: true
