Learn by Doing

• Try OCaml Online (by OCamlPro) allows you to immediately start learning OCaml in your browser, without installing it. Compiled as a single Javascript page, it gives you the full power of OCaml, even when your are disconnected from the network.
• PLEAC-OCaml provides OCaml solutions to the complete set of problems originally posed in the very successful Perl Cookbook. OCaml is one of only 3 languages for which the full set of solutions has been provided.
• Rosetta is a programming chrestomathy site. It provides solutions to the same task in many languages. Currently there are few tasks with OCaml solutions provided, but perhaps you would like to add new solutions.

Tutorials on OCaml

• The OCaml System (by Inria) is the official user's manual. The first part provides an introduction to the core language, objects and classes, and modules. Previous versions are here.
• Tutorial on the C API (by Florent Monnier) explains how to write C stubs to call C functions from OCaml and back.
• OCaml for scientific computation (by Thomas Fiscbacher), covers a broad sample of OCaml, from the basics to the C api.
• A Concise Introduction to OCaml (by David Matuszek) gives a concise, yet broad, overview of the language and the standard library. It is rather old but most of what it says remains valid.
• How to wrap C functions to OCaml (by Florent Monnier) explains how to write extensions for OCaml in C in an understandable way and features a lot of examples.
