Embedded domain-specific languages

Two lectures at the British Computer Society in Covent Garden on Friday 18 May.

Embedding a DSL in a programming language is a low-cost strategy that doesn't sacrifice the power or generality of the programming language. Call this the agile approach to DSLs; an approach more suitable for some languages than others.

iPod – iTunes – iDyalog

"If music be the food of love…" John Daintree leaps into action with a DSL for iTunes so he can summon his date's favourite tune as soon as he gets her home. (Show us your moves, John.)

Go Fish!

Morten Kromberg previews an open-session workshop prepared for XP2007 in Como this summer and tested earlier this year in Gothenburg.

The workshop seeks a DSL to play Go Fish! and explores solutions embedded in Python, Ruby and Dyalog APL. For domain-driven design, much turns out to depend on the level of semantic density achievable. Morten shows us in Dyalog just how much you can get done with nothing but the PL.
