Colour me impressed. I thought you needed fancy (relatively) modern stuff like Ruby for decent in-language DSLs, but clearly Bash can do the trick, too.

I wonder how decent a programming language you could turn bash into using tricks like these.

You can in fact write a web framework for Bash using tricks like these: Bash on Balls has a HTTP parser and router, a model layer that implements OO similarly to this, even a templating language, esh

And if you're stuck in the Microsoft ecosystem there is DOS on Dope: http://secretgeek.net/dod_intro.asp

Ha ha! Brilliant. An incredibly suitable domain name for such and insane monster!

Doesn't look like you can do polymorphism with it, which would be the real utility of this. Objects are globally named, etc.

But looks fun!

Why can't you do polymorphism? It looks like he just needs to add vtables to make that work.

You don't need bash features to do this either. I wrote shoop (http://shoop.sourceforge.net/) a decade ago.

You can do this in straight shell, with polymorphism. See http://onestepback.org/articles/poly/sp-shell.html.

And see http://onestepback.org/articles/poly/index.html for the same example in many, many other languages.

I used this to make a utility logging class for bash scripts. It prints nicely formatted messages to the console and/or logfile. The format is similar to Linux boot messages.

This is bad a joke - not only the classes and methods but the individual instances have statically generated names. That means in the examples, for the statically generated "one", "two" and "three" there's no way to assign them to another variable, or pass them as arguments to a function.
