How-tos
User Interface
Very nice guide about IntelliJ user interface.
Erlang SDK setup
You need to specify a directory that contains bin directory with erl and erlc executables inside.
Also that directory should contains releases dir inside.
Some predefined paths:
Also that directory should contains releases dir inside.
Some predefined paths:
- /usr/lib/erlang (Linux)
- /opt/local/lib/erlang (Mac Ports on Mac OS X)
- /usr/local/Cellar/erlang/R*/lib/erlang (Homebrew on Mac OS X)
Rebar integration
First of all, you need to provide the right path to the Rebar executable (Settings > Erlang External Tools).
Note for Mac OS X users. Please, check that the PATH for IntelliJ contains rebar executable.
For further information see Stackoverflow answer and
#189 issue.
Note for Windows users. Please checkout how to install rebar for Windows.
After you have set your rebar path up you can create a new Rebar run configuration(Run > Edit run configurations...),
use a little green button on the top left corner:
use a little green button on the top left corner:
Or execute an existing one (Run > Run...)
You may create run configuration for every command which Rebar supports, e.g. 
compile or clean, etc.
Skip dependencies checkbox adds
skip_deps=true command for Rebar executable.
To run eunit tests with rebar you can either create a Rebar Eunit run configuration or use a right-click context menu item 'Run ...' or 'Create ...' having clicked on a module(s), a unit test or a generator function you want to run.
Rebar-based Eunit test runner:
To set rebar as a default build action make sure you have checked Compile project with rebar checkbox:
After that your project will be built with 'rebar compile' command when you run Build > Make Project.
Compilation result:
Project structure
In version 0.5 we've added additonal per-module configuration parameters(see Project Structure > Modules).
There you can setup your modules' include paths and global parse transformations.

Debugger
Version 0.5 introduces experimental Erlang debugger support.
In order to use debugger you need to have debug_info checkbox under Settings > Compiler > Erlang Compiler checked.
You also need an Erlang Application run configuration which will be used by debugger. Such configuration can be created by right-clicking on entry point function.
Then you can use this configuration to debug your program:
The debugger requires Erlang Port Mapper Daemon (epmd) to be running. If it's not up, a warning will be issued. To start the daemon run any Erlang node on your machine, for example with erl -sname foo -s init stop -noshell command.
