redcloth - What does this construction mean, in Ruby? -

-

the method below exists in redcloth gem.

my question is: construction "to(redcloth::formatters::html)" mean? "to" isn't method in class, nor in superclass (wich string class).

cheers. christian.

def to_html( *rules )   apply_rules(rules)   to(redcloth::formatters::html) end

when search entire redcloth source def to, besides finding couple of methods start to, you'll find exact method to in ext/redcloth_scan/redcloth_scan.rb.rl.

there's 2 things happen here. first, file preprocessed ragel. question, may safely ignore fact , read past weird syntax in file. focus on ruby bits.

second, class redcloth::textiledoc reopend here. means class in file , in lib/redcloth/textile_doc.rb same. to instance method available piece of code quoted.
