How-tos

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 Download erlang documentation htmlreleases 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)
If something goes wrong you always may reopen the #31.

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:
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.
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.

In this article, the development of one to one chat app from scratch is discussed in detail. The technical stack involved in WhatsApp like chat app are Erlang (Language), Ejabberd (Framework), XMPP protocol, MySQL (Database). The following steps will help you to develop a one to one chat application in an hassle-free manner.

The parameters involved to develop one on one chat are as follows

  • Erlang
  • MySQL
  • Ejabberd
  • PSi+
  • One to One chat
Download

Here is the procedure to develop on to one chat app.

Install and Setup Erlang on Ubuntu

Erlang is a functional programming language and open source used for high scalability and availability for system requirements. Erlang shows the concept “Write Once and Run Forever”. Erlang / OTP (Open Telecom Platform) are interchangeable consists of a collection of libraries, design principles like (soft real-time, distributed, fault tolerance etc) that are written in Erlang language to support the high run-time system and scalability.

The following steps are the installation procedure of Erlang in the Ubuntu server:

Erlang Download Mac Free

Step 1: Download the Erlang in the Ubuntu Server

  • In Linux server, download the Erlang source file using the below link. Here Erlang version of 18.0 is used and this extends the updates regularly.
  • Thewgetcommandis used to download the Erlang source files.

Step 2: Extract the Erlang tar File.

Extract the downloaded tar file using the command.

Step 3: Adding Dependencies in the Command

Provide the required dependencies in the single library function to perform a specific task. Below listed are the dependencies that will do a certain task.

Step 4: Start compilation and Install the Erlang

To compile the source code use “make” command that starts to execute the file and finally install the Erlang using “make install” on the Linux server. The “configure” command will help you to verify the dependencies.

Install MYSQL and Import Ejabberd DB

Install the MySQL database using the below command:

1. While the installation of MySQL Server packages, you will get a screen tosetupthe MySQL root password on your terminal. Provide the MySQL user root password.

2. Confirm once again with the popup.

3. After the installation of MySQL server, it runs the MySQL service automatically. Once it is done, you can log in the MySQL Server with user root and password that is already defined.

To log in to MySQL Server, use the below-given command. It tells to enter the MySQL root password which you have already set during the installation of MySQL server.

4. To check MySQL server status run the following command

5. To create the database, use the below command

Pop-up shows to enter the MySQL password, and then createdatabasefor one-one chat users

Copy the Ejabberd MySQL database structure from the below link and save to mysql.sql file

Import Ejabberd database structure to chat database.

Ejabberd is an XMPP (Extensible Messaging Presence Protocol) programming server written using Erlang programming language. One of the most popular open sources and free software. Ejabberd runs on multiple operating systems like Linux, Mac, Unix, Windows etc. XMPP is the backbone that allows sending real-time messages, online presence indicators, XML routing features and more.

The installation of Ejabberd XMPP server on Ubuntu 14.04/16.04 in detail.

Step 1: Download the Ejabberd in the Ubuntu Server

  • In Linux server, download the ejabberd source file using the below link. Here Ejabberd version of 16.08 is used and this extends the updates regularly.
  • The wget command is used to download the Erlang source files.

Step 2: Extract the erlang tar file.

Extract the downloaded tar file using the command.

Step 3: Adding Dependencies in the Command

Provide the required dependencies in the single library function to perform a specific task. Below listed are the dependencies that will do a certain task.

Erlang Download Mac

Step 4: Fix and Verify the Issue

autogen.sh used for compilation, verification of the functionality and overcome the initial issues.

Step 5: Start execution and Install the Ejabberd

To compile the source code use “make” command that starts to execute the file and finally install the Erlang using “make install” on the Linux server. The configure command will help you to verify the dependencies.

Step 6: Open the Ejabberd configuration file

Using the command, open the Ejabberd file to set the database.

Provide MySQL database IP, Database name, username, the password for the confirmation.

Finally, save the file /etc/ejabberd/ejabberd.yml

Step 7: Run the Ejabberd

Once the changes are done, run the Ejabberd which in turn helps to refresh the database.

Step 8: Check the Status using Local Host

To verify and to check the status of the ejabberd installation use the below command.

The node Ejabberd at Localhost starts with the status command and shows the ejabberd 0.0 is running

Using a localhost IP “http://localhost:5222” the browser displays the text that is similar to the XML

Register the users in Ejabberd using the below displayed code:-

Using Ubuntu software center, download the PSi+ and install the software.
Follow the guidelines and screenshots to register the users and create a 1–1 chat application:
1. Click the bottom icon to setup & add the account for “User1″.


2. Go to Account setup, enter “User1” and then click “add button”.


3. Provide XMPP address as “user1@localhost” or server IP and enter the password as given on the Ejabberd registration database.


4. A popup displays, just close the window.


5. Repeat the steps from 1 to 3, to register the “User2”.

6. In “User1”, do right click to enable the status “online” and repeat the same for “User2”.


7. To add the contact in “User2”, do right-click and click the “Add Contact” button. Then enter the XMPP address of “User1” (User1@localhost)
