Tomas Petricek on Domain Specific Languages in F#

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. When 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 for describing our problems. Using the flexible F#
syntax, we can get code that even non-programmers can understand.

In this practically oriented talk, we'll develop a number of sample DSLs,
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.

Tomas is a long-time F# enthusiast, Microsoft MVP and author of a book
Real-World Functional Programming (http://manning.com/petricek). He leads
functional programming and F# courses in London and New York and contributed to the development of F# as an intern and contractor at Microsoft Research in Cambridge. He is a PhD student at University of Cambridge, working on functional programming languages.

    Thanks again, Tomas, for the talk. It was a great experience.

    Will the video recording be posted here? I would like to be able to review the time series example.

      Most certainly. It usually takes about a week to get the video up.

    Meet, socialize and network tonight w/ Richard and many others at the meetup. It is one of the most popular (tech) events in NYC today!

    We built an easy-to browse/search page for/with all attendees: http://bit.ly/X6IbPC

    Happy networking!

    I wish to bring a colleague from work who is very interested in F#.

      Sure thing, just have them sign up so we can get their real name for security.

    I would love to come, but time-vise, I will not be able to make it ...
    Funnily enough, currently I am trying to use Smalltalk as DSL for writing cross platform mobile apps, but I got feeling, that F# fits better this task . I am quite eager to learn more about using F# for writing DSL...
