Dsl/library for text interaction?

Ruby
1

I’ve been doing a fair amount of work with Asterisk lately. It’s got a
command-line interface that looks quite a bit like SMTP (and like lots
of
other text-based send-a-line-and-get-a-response protocols).

Seems like there should be a generic library to build interfaces for
these
sorts of things - is there? Some sort of DSL that helps you say things
like:

  • the first thing on the line is the command “FOOBAR”

  • it takes two required arguments, and one optional

  • encode the required arguments using (base64/http/whatever)

  • the response is one line starting with an integer result code

  • when you get a response matching code X, execute a given block

  • etc

Perhaps you could use a parser generator?

If the data is regular enough, RedNails might do the trick
