Book Description

Using Erlang, you’ll be surprised at how easy it becomes to deal with parallel problems, and how much faster and more efficiently your programs run. That’s because Erlang uses sets of parallel processes—not a single sequential process, as found in most programming languages.

Joe Armstrong, creator of Erlang, introduces this powerful language in small steps, giving you a complete overview of Erlang and how to use it in common scenarios. You’ll start with sequential programming, move to parallel programming and handling errors in parallel programs, and learn to work confidently with distributed programming and the standard Erlang/Open Telecom Platform (OTP) frameworks.

You need no previous knowledge of functional or parallel programming. The chapters are packed with hands-on, real-world tutorial examples and insider tips and advice, and finish with exercises for both beginning and advanced users.

The second edition has been extensively rewritten and covers Erlang R17 features. New to this edition are seven chapters covering the latest Erlang features: maps, the type system and the Dialyzer, WebSockets, programming idioms, and a new stand-alone execution environment. You’ll write programs that dynamically detect and correct errors, and that can be upgraded without stopping the system. There’s also coverage of rebar (the de facto Erlang build system), and information on how to share and use Erlang projects on github, illustrated with examples from cowboy and bitcask.

Erlang will change your view of the world, and of how you program.
