Ameba::Rule::Lint::AmbiguousAssignment

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

This rule checks for mistyped shorthand assignments.

This is considered invalid:

x =- y
x =+ y
x =! y

And this is valid:

x -= y # or x = -y
x += y # or x = +y
x != y # or x = !y

YAML configuration example:

Lint/AmbiguousAssignment:
  Enabled: true
