rlisp

Probably the worst gem/DSL/idea for ruby ever. A lisp-like language as a DSL! Very WIP.

Here's a code example!

require 'rlisp'

Rlisp do
  [
    [:defn, :div_by, [:a, :b], [:eql, 0, [:mod, :a, :b]]],
    [:defn,:fizz_buzz, [:a],
      [:if, [:div_by, :a, 15],
        'FizzBuzz',
        [:if, [:div_by, :a, 3],
          'Fizz',
          [:if, [:div_by, :a, 5],
            'Buzz',
            :a
          ]
        ]
      ]
    ],
    [:print, [:map, :fizz_buzz, [:range, 1, 101]]]
  ]
end

What can it do?

• The operators you might expect
• Quotes, for delaying execution
• defn for defining functions
• map and filter
• range for generating a range of numbers
• Standard equality checkers eq and eql (not confusing at all)
• A ruby fallback, so if your ruby method is defined somewhere, it may just work!
• a print function (really just ruby's puts, shhhh)
• An if conditional, so you can work that logical magic

See ./spec/lib/rlisp_spec.rb for proven, working examples!

TODO

• recursion is broken...
