Capricc-Io

Capricc-Io is a tiny interpreted prototyped-based homoiconic and dynamic typing language with Io-like messages.

• Everything is an object in Capricc-Io;
• Program is just a series of messages;
• Objects don’t have classes, but prototypes, their parent objects;
• Messages are the only data type and also parsing representation → homoiconicity;

In lib/capriccio/stdlib you can see how you can define an if statement or booleans behavior directly in Capric-Io;

Installation

$ gem install capricc-io

Usage

Run REPL:

capio

or run file:

capio your_code.cio

Examples of code

Prototypes & OOP:

# comment

set("person", Object clone)
person set("name", "Max")
person name print
# => Max

person set("say_name", def(
  arguments print
  # => <Message @name="hello...">

  eval_arg(0) print
  # => hello...

  self name print
  # => Max
))

person say_name("hello...")

Conditions:

if(true,
  "condition is true" print,
  "nope" print
)
# => condition is true

if(false,
  "nope" print,
  "condition is false" print
)
# => condition is false

Booleans:

"yo" or("hi") print
