About Erlang<\/h3>\n

Erlang is a functional programming language<\/strong> which has many features more commonly associated with an operating system than with a programming language: concurrent processes, scheduling, memory management, distribution, networking, etc.<\/p>\n

The initial open-source Erlang release contains the implementation of Erlang, as well as a large part of Ericsson’s middleware for building distributed high-availability systems<\/strong>.
\n<\/p>\n

Installing Erlang<\/h3>\n

Ubuntu & derivatives<\/h4>\n

If I am not mistaken, in Ubuntu 10.04+, Erlang system is preinstalled, because it is used by some other subsystems, such as CouchDB database.<\/p>\n

In Ubuntu, you can install Erlang from the repositories:<\/p>\n

\r\n$ sudo apt-get install erlang\r\n<\/pre>\n
The version installed will not be the latest, but this should not bother you for now..<\/p>\n
Building from source<\/h4>\n
You can download Erlang source from here<\/a>. Untar the downloaded file, nagivate into the folder and run the configure script:<\/p>\n
\r\n#you can use the --prefix=\/path\/to\/the\/installation\/folder\r\n#the default is \/usr\/local\/lib\/erlang\r\n$ .\/configure \r\n<\/pre>\n
If no problems appear, run:<\/p>\n
\r\n$ make \r\n<\/pre>\n
and then<\/p>\n
\r\n#as the root user, or \"sudo make install\"\r\n$ make install \r\n<\/pre>\n
Windows<\/h4>\n
Download and run the installer<\/a>.<\/p>\n
Accessing the Erlang Emulator<\/h3>\n
Erlang Emulator<\/strong> is an interactive shell which you can use to test and run your code.
\n
\"Erlang<\/a>
Erlang Emulator<\/p><\/div>
\nIn order to get access to the emulator do:<\/p>\n
Linux, Mac OS X, and Unix<\/h5>\n
Open a terminal and type:<\/p>\n
\r\n$ erl\r\n<\/pre>\n
Windows<\/h5>\n
You can either click the Erlang icon created by the installer or run the werl<\/code> command.<\/p>\n
Quit<\/h5>\n
In order to exit the emulator type <\/p>\n
1> q().<\/pre>\n
Programming Editor\/IDE<\/h3>\n
Emacs<\/h4>\n
I personally use Emacs for programming Erlang. There is an Erlange editing mode in Emacs. In Ubuntu you can install it by:<\/p>\n
\r\nsudo apt-get install erlang-mode\r\n<\/pre>\n
Details here<\/a>.<\/p>\n
Erlide for Eclipse<\/h4>\n
There is an Eclipse plugin supporting Erlang called Erlide. For download and installation details go here<\/a>.<\/p>\n
Others<\/h4>\n
There are some other alternatives, including a Netbeans IDE plugin<\/a>. For more details go here<\/a>.<\/p>\n
Documentation<\/h3>\n
You can access Erlang Documentation online<\/a>. <\/p>\n
What I use the most is the Manual Pages<\/a>. It is a very useful resource since there are tons of built-in function that will help you avoid reinventing the wheel..<\/p>\n
Next<\/h3>\n
The next post will be about the basic types in Erlang..<\/p>\n","protected":false},"excerpt":{"rendered":"
