Question

Can I someway introduce indentation based hashes in ruby? Something like coffescript hashes.

a: 1
  b: 
    c: 3
    d: 4
  e:
    f: 'qwe'

Answer 1

Yeah, you can either implement a method to parse hashes from strings using indentation as delimiters, or, as @AJcodez suggested:

require 'psych'
require 'yaml'

yash = <<EOT  # type hashes like this
---
:a:
- 1
- :b:
    :c: 3
    :d: 4
  :e:
    :f: qwe
EOT

hash = YAML.load yash
=> {:a=>[1, {:b=>{:c=>3, :d=>4}, :e=>{:f=>"qwe"}}]}
