T1: Real-World OCaml (Anil Madhavapeddy, University of Cambridge; Yaron Minsky, Jane Street)

Abstract:

OCaml is a statically typed functional language with a fast native code compiler and incremental garbage collector. In this tutorial, we will first introduce the basics of OCaml using an interactive environment running in a web browser, and the OPAM package manager. Then, we will introduce Jane Street's Core library, which is an industrial-strength alternative to the OCaml standard library. Core is designed with consistency, explicitness and efficiency in mind. Finally, we will demonstrate how to build fast Internet services such as a database-driven webserver using the Lwt asynchronous programming library and other open-source tools.

Expectations

By the end of the tutorial, attendees will be familiar with basic OCaml syntax and how to install useful packages such as Core and Lwt. They will also understand how to build network servers for Internet serving.

Preparation

Please bring a laptop to the tutorial. Ideally, you should install the required software on your laptop before the tutorial. If that fails, we'll have a machine on-site for you to connect to. In that case, make sure to have an RDP client (a client for Microsoft's Remote Desktop protocol) installed on your laptop, so you can connect to our on-site machine.

If you have problems or questions, please contact Mike Sperber (sperber(at)deinprogramm(dot)de).

Installing the prerequisite software

For the OCaml tutorial, you will only need:

After that, you run opam install core async lwt, and that will install all the packages required for the tutorial material.
