YAML in Ruby

While using Ruby, there are many situations where we may want to create some configuration files while working on a productive application. We may want to install our productive application to the client’s server and make it easier, and we need to make configuration files.

We will use the YAML library for this task. YAML stands for yet another mark-up language, but YAML is not a mark-up language.

In the YAML module, Ruby provides data serialization. YAML targets the same communications applications as Extensible Mark-up Language (XML) but has a minimal syntax that intentionally differs from Standard General Mark-up Language.

Steps to Install YAML in Ruby

If we want to install YAML on Ubuntu in Ruby, we can do it by running the following command.

sudo apt-get update -y
sudo apt-get install -y ruby-safe-yaml

On the other hand, if we want to install YAML on Mac, we need to install Ruby using Homebrew, and after that, libyaml is included in the list of dependencies installed for Ruby. We can use the following command to install Ruby using Homebrew.

brew install ruby

Load YAML File in Ruby

We can use the YAML library by using the following line of code in our application, as shown below.

require 'yaml'

While working with YAML in Ruby, we may want to load a YAML file in Ruby. YAML library provides an easy method to load a YAML file.

Below is an example of loading a YAML file in Ruby.

require 'yaml'
file = YAML.load_file('new.yml')
puts file.inspect

We can easily load any YAML file into our Ruby program using the YAML library.
