Ruby Usage

File prog.rb:

require 'yamlscript'
input = IO.read('file.ys')
ys = YAMLScript.new
data = ys.load(input)
puts data

File file.ys:

!YS-v0:

name =: "World"

foo: [1, 2, ! inc(41)]
bar:: load("other.yaml")
baz:: "Hello, $name!"

File other.yaml:

oh: Hello

Run:

$ ruby prog.rb
{"foo"=>[1, 2, 42], "bar"=>{"oh"=>"Hello"}, "baz"=>"Hello, World!"}

Installation

You can install this module like any other Ruby module:

gem install yamlscript

but you will need to have a system install of libys.so.

One simple way to do that is with:

curl https://yamlscript.org/install | bash

> Note: The above command will install the latest version of the YAMLScript
command line utility, ys, and the shared library, libys.so, into
~/local/bin and ~/.local/lib respectively.
