Ruby client library for JDoodle API.

⬇ Installing

If you are using Bundler, add the following line to your Gemfile:

gem "jdoodle"


If you are not using Bundler, use the gem install command:

$ gem install jdoodle

🕹 Usage

First you need to create an account on JDoodle's website. After that you must pick a plan. That will give you a client ID and a client secret. You will need that to make requests. Now you can go back to your Ruby project, require JDoodle and instantiate a client:

# Requiring JDoodle client library
require "jdoodle"

# Instantiating a client
jdoodle = JDoodle::Client.new(
  client_id: "CLIENT_ID_HERE",
  client_secret: "CLIENT_SECRET_HERE"


To check how many credits the client has spent today, use Client#credit_spent:

jdoodle.credit_spent # => 4

Executing Snippets

To execute a snippet of code, use Client#execute:

# If your code takes up more than one line, it is
# recommended to use the squiggly heredoc syntax.
code = <<~CODE
  #include <stdio.h>

  int main()
    printf("Hello, World!");
    return 0;

jdoodle.execute(:c, code)

# If not, go for the shorter way.
jdoodle.execute(:ruby, "puts 'Hello, World!'")

This will return an object, which has four read-only attributes: cpu_time, memory, output and status_code.

response = jdoodle.execute(:python3, "print('Hello, World!)'")

p response.cpu_time # => "0.01"
p response.memory # => "5280"
p response.output # => "Hello, World!\n"
p response.status_code # => 200
