• Object
• LibRubyParser::Node
• LibRubyParser::Nodes::MatchCurrentLine

Defined in:

lib/lib-ruby-parser/nodes.rb

Overview

Represents implicit matching using if /regex/

if /.*/
puts 'true'
else
puts 'false'
end

Prints "false".

Under the hood this construction matches regex against $_, so the following works:

$_ = 'match_me'
if /match_me/
puts 'true'
else
puts 'false'
end

this code prints "true".

def expression_l
  @expression_l
end

#re ⇒ Node (readonly)
