Welcome to Erlang/OTP, a complete
for concurrent programming.
Some hints that may get you started faster
- The Erlang programming language is described in the book
Concurrent Programming in Erlang, ISBN 0-13-285792-8, 2nd
edition. The first part of the book is available as a PDF document.
However, the language has evolved since the book was written,
and a more up to date description can be found in The Erlang
Reference Manual. An Erlang tutorial can be found in
Getting Started With Erlang.
- Erlang/OTP is divided into a number of OTP applications. An application normally contains
Erlang modules. Some OTP applications,
such as the C interface, are written in other languages and have no Erlang
Note that functions that are not imported or prefixed with a module
name belong to the built-in module erlang
(in the Kernel application).
- On a Unix system you can view the manual pages from the command
% erl -man <module name>
- If you want to search the complete documentation you can use this
- You can of course use any editor you like to write Erlang
programs, but if you use Emacs there exists editing support such as
indentation, syntax highlighting, electric commands, module name
verification, comment support including paragraph filling, skeletons,
tags support and more. See the tools applications for details.
- When developing with Erlang/OTP you usually test your programs
from the interactive shell where you can call individual
functions. You can also start the graphical debugger, process monitor and table viewer from the shell.
Also note that there are some shell features like history list
(control-p and control-n), in line editing (emacs key bindings) and
module and function name completion (tab) if the module is loaded.
- There are some suggestions for best practice and performance
hints using Erlang/OTP.
- A fast way to learn the Erlang language and OTP is attending one
of the courses offered by Ericsson and others.
There is also a certification program.
- If you are a paying customer you can get support and request bug
fixes from <firstname.lastname@example.org>. OpenSource users can ask questions
and share experiences on the Erlang questions mailing list.
- Before asking a question you can browse the mailing list archive and read the Frequently
