Pattern: if with boolean literal branches

Issue: -

Description

This rule checks for redundant if with boolean literal branches. It checks only conditions to return boolean value (true or false) for safe detection. The conditions to be checked are comparison methods, predicate methods, and double negative. However, auto-correction is unsafe because there is no guarantee that all predicate methods will return boolean value. Those methods can be allowed with AllowedMethods config.

Examples

# bad
if foo == bar
  true
else
  false
end

# bad
foo == bar ? true : false

# good
foo == bar
