Pattern: Use of custom global variable
Issue: -
This rule looks for uses of global variables. It does not report offenses for built-in global variables. Built-in global variables are allowed by default. Additionally users can allow additional variables via the AllowedVariables option.
Note that backreferences like $1, $2, etc are not global variables.
# bad
$foo_bar = 1
# good
module Foo
class << self
attr_accessor :bar
end
end
Foo.bar = 1| Attribute | Value |
|---|---|
| AllowedVariables |
