Progressive F# Tutorials - New York City 2012 / Domain-specific languages in F#

Please RSVP for instructions on how to join the event.

Description

When designing software, developers often need to solve numerous instances of a single problem. Examples include writing business rules engine, detecting patterns in changing prices and many others. Domain specific languages (DSLs) provide a powerful mechanism for solving such problems – by designing a single composable library (or a language), we get a tool that can be used to solve a number of instances of the same problem. In this tutorial, you’ll learn how to write two kinds of domain-specific languages in F#. We start by looking at languages that are implemented as F# libraries and then we move on to writing your own parsers for custom spreadsheets.

In this article, I explore the amazing relationship between functional data types and algebraic operations. We will use this relationship to reason about domain model and understand the differences between several possible representations.

This article introduces a new F# package that makes it possible to write literate F# programs that combine code with documentation. Given an F# script with a special comments or Markdown document with F# code, you get a nicely formatted HTML that can be u[...]
