Removes the last RubyLex's instance variable
@prompt
and@line_no
.Reason:
@line_no
is completely controlled by IRB::Irb with@scanner.increase_line_no
. It should be IRB::Irb's instance variable.@scanner.set_prompt do end
and@scanner.prompt(args)
seems roundabout.I wanted to remove
save_prompt_to_context_io
because the flow is complex and hard to understand.After deleting
@prompt
and@line_no
from RubyLex, RubyLex will have no state at all. RubyLex does not have to be a class anymore.
