# Constructs a parser using a Parser Expression Grammar like DSL:
parser = str('"') >>
(
str('\\') >> any |
str('"').absent? >> any
).repeat.as(:string) >>
str('"')
# Parse the string and capture parts of the interpretation (:string above)
tree = parser.parse('"This is a \\"String\\" in which you can escape stuff"')
tree # => {:string=>"This is a \\\"String\\\" in which you can escape stuff"}
# Here's how you can grab results from that tree:
transform = Parslet::Transform.new do
rule(:string => simple(:x)) {
puts "String contents: #{x}" }
end
transform.apply(tree)
