Short Description
The course focuses on the basic concepts of Clojure with respect to functional programming, concurrency, and interoperability with Java.
Learning Objectives

The students are familiar with the basic concepts of Clojure, know how to do functional programming and master concurrency in Clojure. They know how to use Clojure in larger projects and know the most important Clojure functions and libraries. They inde-pendently solve problems using the functional paradigm and recognize its suitability and limitations.

  • Read-Eval-Print-Loop: reader, evaluator, syntax, homoiconicity
  • Functions: definition, values and functions, higher order functions, pure functions, side effects
  • Recursive functions: recursion and iteration, tail recursion, alternating recursion
  • Values und Data structures: simple types, complex types, destructuring
  • Abstractions: collection, sequence, associative, indexed, stack, set, sorted
  • Data types and Polymorphism: multimethods, records, protocols
  • Identity, State & Concurrency: concept, vars, atoms, refs, agents, STM
  • Macros: syntax, idioms and patterns
  • Java Interoperability: using Java, exceptions, type hints, arrays, classes and interfaces
  • Logic Programming: core.logic
  • Parser combinators
  • Software Engineering with Clojure: namespaces, metadata, testing, assertions, performance
  • Real World Clojure: GUI, Web,database access
  • Interesting Libraries: quil, Incanter, Cascalog, ...
