objective-lol 0.0.9

Python bindings for Objective-LOL

Objective-LOL Python Bindings

Python bindings for the Objective-LOL programming language - a modern, strongly-typed language inspired by LOLCODE.

Installation

pip install objective-lol

Quick Start

import objective_lol as olol

# Create a VM instance
vm = olol.ObjectiveLOLVM()

# Execute Objective-LOL code
code = """
I CAN HAS STDIO?
HAI ME TEH FUNCSHUN MAIN
    I HAS A VARIABLE X TEH INTEGR ITZ 42
    SAYZ WIT X
KTHXBAI
"""

vm.execute(code)  # Prints: 42

Features

• Execute Objective-LOL code: Run complete programs or code snippets
• Python integration: Call Python functions from Objective-LOL and vice versa
• Type conversion: Automatic conversion between Python and Objective-LOL types
• Module system: Import and use custom modules
• Class definitions: Define and use classes from Python

Advanced Usage

Defining Python Functions for Objective-LOL

vm = olol.ObjectiveLOLVM()

def add_numbers(a, b):
    return a + b

vm.define_function("add_numbers", add_numbers)

code = """
I CAN HAS STDIO?
HAI ME TEH FUNCSHUN MAIN
    I HAS A VARIABLE RESULT TEH INTEGR ITZ add_numbers WIT 10 AN WIT 20
    SAYZ WIT RESULT
KTHXBAI
"""

vm.execute(code)  # Prints: 30

Working with Classes

vm = olol.ObjectiveLOLVM()

class Calculator:
    def add(self, x, y):
        return x + y

    def multiply(self, x, y):
        return x * y

vm.define_class(Calculator)

code = """
I CAN HAS STDIO?
HAI ME TEH FUNCSHUN MAIN
    I HAS A VARIABLE CALC TEH Calculator ITZ NEW Calculator
    I HAS A VARIABLE SUM TEH INTEGR ITZ CALC DO add WIT 5 AN WIT 3
    SAYZ WIT SUM
KTHXBAI
"""

vm.execute(code)  # Prints: 8

Changelog

[0.0.9] - 2026-05-01

Fixed

• Fixed incorrect serialization of unknown function handler return values

[0.0.8] - 2026-04-30

Changed

• Class member variable type annotations are now optional, allowing dynamic typing consistent with global and local variable declarations

[0.0.7] - 2026-04-30

Changed

• Proxy methods now determine their async/sync interface based on whether the VM was initialized with an asyncio loop, rather than inspecting the wrapped method's own async signature
• Error messages from Python callbacks now include the exception type (e.g. ValueError: ... instead of just the message text)

Fixed

• Member variable getter errors are now propagated as interpreter exceptions instead of being silently swallowed
• Function and method call failure messages now include the function/method name for easier debugging

[0.0.6] - 2026-04-30

Changed

• Refactored asyncio threading shims into factory methods (_run_in_loop, _run_blocking, _make_loop_method_wrapper, _make_loop_wrapper) to eliminate duplicated thread+Future patterns
• Getter and setter registrations now route through the asyncio event loop when one is provided, consistent with method dispatch

[0.0.5] - 2026-04-29

Changed

• Replaced prefer_async_loop with an explicit asyncio_loop to specify which event loop to use
• Changed interop of sync Python methods to be called within the asyncio loop, if one is provided
• Changed interop of async Python methods to require an asyncio loop

[0.0.4] - 2026-04-29

Added

• Added a mechanism to specify the working directory of the Objective-LOL interpreter from Python at initialization time

Fixed

• Fixed interop of setting primitive values on Python objects from within Objective-LOL

[0.0.3] - 2026-03-24

Fixed

• Fixed interop of nested lists and dicts between Python and Objective-LOL

[0.0.2] - 2025-09-16

Changed

• Modified octal prefix from 0 to 0o

Fixed

• Fixed a stack corruption crash on Windows by using compatibility function calls with separate goroutines

[0.0.1] - 2025-09-14

Added

• Initial Python bindings for Objective-LOL interpreter
• Pre-built wheels for Windows, macOS, and Linux for Python 3.9+
