Class: RuboCop::Cop::Style::BracesAroundHashParameters
- Includes:
- ConfigurableEnforcedStyle, RangeHelp
- Defined in:
- lib/rubocop/cop/style/braces_around_hash_parameters.rb
Overview
This cop checks for braces around the last parameter in a method call if the last parameter is a hash. It supports ‘braces`, `no_braces` and `context_dependent` styles.

Instance Method Details
#autocorrect(send_node) ⇒ Object
We let AutocorrectUnlessChangingAST#autocorrect work with the send node, because that context is needed. When parsing the code to see if the AST has changed, a braceless hash would not be parsed as a hash otherwise.
