Introducing Erlang, 2nd Edition

Chapter 12. Next Steps Through Erlang

Hopefully you now feel comfortable writing basic Erlang programs, and understand roughly how modules and processes build into programs. You should be ready to experiment with writing Erlang code, but more importantly, you should be ready to explore other resources for mastering Erlang and its many powerful libraries. There’s a lot to explore!

Moving Beyond the Erlang Shell

The Erlang shell is a great place to test code and to poke and prod Erlang code. You’ll likely spend a lot more time in the shell if you keep using Erlang, but the way you use it may change.

You can compile and run Erlang code outside of the shell, which makes it much easier to integrate Erlang work with tools you typically use to manage code and related resources. Erlang’s make module is a common place to start, letting you create Emakefile files that provide instruction to the erl -make command. The escript command, described at http://erlang.org/doc/man/escript.html, will let you run Erlang from the command line in a variety of different environments.

If you want to automate your Erlang builds further, you may want to explore rebar3. You can mix rebar3 with other tools to apply the strengths of each.

If you want to use Erlang from an IDE, you may want to explore http://erlide.org/, a set of tools for working with Erlang in Eclipse. Emacs users will want to explore the Erlang mode.
