Maroon is a pirate-themed programming language that makes coding as adventurous as sailing the high seas! Written in Python, it features a unique syntax inspired by pirate parlance while maintaining functional programming capabilities.

Update v1.1

New Control Structures

While loops with comparison operators

while counter be less_than 3 bark counter

Plunder loops (foreach)

plunder each coin from treasure_chest bark coin

Repeat loops

repeat 3 times bark "BOOM!"

Choose statements (switch/case)

choose x:
    case 1: bark "one"
    default: bark "unknown"
end choose

Error Handling

brace for impact:
    bark "Dangerous waters"
if capsized, bark "Error!"

Functional Operations

• List comprehension: list of 1, 2, 3 where each times 2
• Filter: coins where it greater_than 5
• Reduce: reduce coins with result plus it

String Operations

• Upper/lower case: "hello" upper
• Split/join: "hello world" split " "

Custom Dialects

dialect Caribbean:
    "shout" be "bark"
    "expedition" be "voyage"
end dialect

Core Syntax

Variable Assignment

treasure be 42
message be "Ahoy, world!"

Arithmetic Operations

• plus: Addition
• minus: Subtraction
• times: Multiplication
• divided_by: Division
• modulo: Modulus
• power: Exponentiation

Built-in Functions

• to_int, to_float, to_str: Type conversion

Function Definition

voyage greet(name):
    bark "Ahoy," name
end voyage

Lists

crew be list of "Jack", "Anne", "Mary"
add "Blackbeard" to crew

Conditionals

if gold be greater_than 100, then bark "Rich!" else bark "Poor!"

Error Handling

The interpreter provides detailed error messages through the PirateException class, helping developers navigate through rough seas of debugging.

Development

The interpreter is built with clean, modular Python code featuring:

• Regular expression parsing
• Robust type system
• Comprehensive operator support
• Modular function handling

Getting Started

1. Clone the repository
2. Run Maroon scripts with .maroon extension
3. Start writing your pirate-themed programs!

Example:

treasure be 42
bark "Me treasure chest holds" treasure "gold pieces!"

4. Run the script with: python main.py yourfilename or python main.py for the shell
