Overview

This cop checks for the placement of the closing parenthesis in a method call that passes a HEREDOC string as an argument. It should be placed at the end of the line containing the opening HEREDOC tag.

Examples:

# bad

   foo(<<-SQL
     bar
   SQL
   )

   foo(<<-SQL, 123, <<-NOSQL,
     baz
   NOSQL
   )

   foo(
     bar(<<-SQL
       baz
     SQL
     ),
     123,
   )

# good

   foo(<<-SQL)
     bar
   SQL

   foo(<<-SQL, 123, <<-NOSQL)
     baz
   NOSQL

   foo(
     bar(<<-SQL),
     123,
   )
