The blog of the F# team at Microsoft
Tonight at ThoughtWorks in San Francisco, 6pm:
When designing software, we often need to solve numerous instances of the same problem. When designing user interfaces, we need to describe the layout and interaction. For financial systems, we need to describe a wide range of financial contracts or, for example, recognize different patterns in price change.
Domain Specific Languages (DSLs) give us a way to solve such repeating problems. By designing a composable functional library, we can build an expressive language to describe our problem. Using the flexible F# syntax, we can get code that even non-programmers can understand.
In this talk, we'll demonstrate how to develop DSLs in practice, using a variety of samples, and ending with realistic examples. We'll cover both basic principles of DSL design, as well as advanced tricks such as using the F# 3.0 query syntax.
