Subject: 24.5; Syntax highlighting: required keyword arguments in ruby are
 highlighted incorrectly

[Message part 1 (text/plain, inline)]

Hi there,


Required keyword arguments (introduced in Ruby 2.1) are being

highlighted in alternating colours rather than consistently.


I have attached example images showing this behaviour. Note that

this only occurs when the the keyword arguments are required, i.e.,

they don’t have a default value. So, the following method signature

would result in the argument colours alternating:


  def foo(bar:, baz:)

  end


While the following method signature would result in all of the

arguments being coloured consistently:


  def foo(bar: true, baz: false)

  end


Also note that inserting a space before the delimiting comma between

the arguments results in consistent colouring:


  def foo(bar: , baz:)

  end


Please let me know if you need any further information.


Thanks very much,


Kieran
