# margaret

[![GPLv3 License](https://img.shields.io/badge/license-GPL%20v3-yellow.svg)](./LICENSE)

Margaret is a modern object-oriented programming language that emphasizes message-passing

paradigms and intuitive object interactions.  Its design features powerful literals and

Smalltalk-inspired messaging patterns for powerful object-oriented capabilities.

- Every value in margaret is a pure object.

- There are no reserved words and no explicit syntax apart from message sending.

- Uses prototypal inheritance similar to Self or Javascript.

- Uses C-style literals like int, float, string.

- Implements tensors, tuples, tables, and bitstrings as modern built-in data structures.

- Runs on a portable, lightweight, embeddable, register based VM.

## Installation

TODO - Write installation instructions

## "Postcard"

```margaret

$Margaret -- #ultimate_answer: x => {

  $true && !$false not not && ($nil is_nil?) if_false: { exit: 0 },

  y = @self methods size + @super to_string length * 42,

  [:symbol, ::label, 42, 42.2, "str", 0b0110, 0xbeef, 0o741, %[y, 42, "val"],

    %{"k1": -42, k2: 43}, %(42, 1::1, 0::1)] each: { elem |

      puts: elem object_id,

    },

  if: x < y then: { x } else: { y },

},

puts: (ultimate_answer: 42),

```
