Overview

Checks that every method definition and attribute accessor has a Sorbet signature.

It also suggest an autocorrect with placeholders so the following code:

“‘ def foo(a, b, c); end “`

Will be corrected as:

“‘ sig { params(a: T.untyped, b: T.untyped, c: T.untyped).returns(T.untyped) def foo(a, b, c); end “`

You can configure the placeholders used by changing the following options:

  • ‘ParameterTypePlaceholder`: placeholders used for parameter types (default: ’T.untyped’)

  • ‘ReturnTypePlaceholder`: placeholders used for return types (default: ’T.untyped’)
