erl_playground

An OTP application to start coding without the boring stuff.

Prerequisites

This project has been written for Mac and Linux environments, theoretically speaking it can run on any environment where a Erlang system is correcty installed, but consider that MS Windows and Erlang are not best buddies. Nowadays it is pretty easy to have Linux systems running in minutes using Virtual Machines, Containers, USB distro or simply double booting your laptop.

In case you use a Mac system, we strongly recommend using homebrew to manage all your packages.

OpenSSL

Check the correct installation process for you environment.

Erlang/OTP 21.3

If you are on Mac, we strongly suggest using kerl to build and install the proper Erlang version on your system. For other environments you can easily find your installation package on ErlangSolutions.

Build & Run

This is a rebar3 project.

Compile GPB

Google Protocol Buffer is automatically compiled starting from the included proto file. Here you can find all the information about it.

What you have out of the box

This is a playgrounf application that allows you to focus on the logic of your system, rather than the boring technical stuff. It includes a basic Erlang/OTP application structure with a TCP client and a TCP server.

Candidate comments

These features has been implemented:

• Automatic responder
• Jokes of the day
• My called id
• Ask the operator And also:
• Limited operators
• Chat
• Client
• Tests

Messages

A new proto message has been implemented (user_request) to send input to the automatron_fsm. Another message has been implemented (test_pid) to ask for the pid to the automatron_fsm during the tests.

Client

Integrated client

You can connect to the server performing:

rebar shell

and

> sockclient:connect().
> sockclient:send_create_session().

After this you can perform user interactions with

> sockclient:send_user_request(Input).

Optional client in Python

You can find the code here.

Tests

Run tests with

rebar shell

and

> ct:run_test([{spec, "spec.spec"}]).
