Software Factories / MPS

Guys,

What do you think about this? They call it Meta Programming, the next revolution in programming.

I'm curious to see links to what you've read, particularly something that connects software factories with metaprogramming.

The only possible connection I see is with the creation of Domain Specific Languages (DSLs).

You are right Mark...I meant those DSL"s. What do you think about these? In particular have you tried the MPS system from Jetbrains?

I think the idea of DSLs is a good one. It allows for very expressive code

I looked at JetBrains' calculator tutorial for MPS and it seems significantly complicated for a fairly simple DSL. Granted, a lot of the work goes into making a language that can explain to you when you're not following certain rules, but still. In a language like Groovy, (J)Ruby, or even Scala you've got a lot of flexibility to craft a DSL subset of the language itself. Assuming you already know one of those languages, you don't have to learn a completely new tool just to write a DSL.

Can we use Groovy to write a DSL? Never thought of it!
