snakia 0.4.2

Modern python framework

🐍 Snakia Framework

API Reference  •  Telegram Chat

Snakia is a modern Python framework for creating applications with Entity-Component-System (ECS) architecture, event system, and reactive programming. Built with performance (maybe) and modularity in mind, Snakia provides a clean API for developing complex applications ranging from games to terminal user interfaces.

✨ Key Features

• 🏗️ ECS Architecture - Flexible entity-component-system for scalable game/app logic
• 📡 Event System - Asynchronous event handling with filters and priorities
• 🔌 Plugin System - Modular plugin architecture for extensibility
• 🎨 TUI Framework - Rich terminal user interface with reactive widgets
• ⚡ Reactive Programming - Observable data streams and reactive bindings
• 🛠️ Rich Utilities - Decorators, properties, platform abstraction, and more
• 🎯 Type Safety - Full type hints and Pydantic integration

⚠️ Experimental Framework
This framework is currently in beta/experimental stage. Not all features are fully implemented, there might be bugs, and the API is subject to change. Use at your own risk! 🚧

🚀 Installation

Prerequisites

• Python >= 3.12
• pip or uv (recommended) package manager

Install from PyPi (recommended)

pip install snakia

Install from Source

git clone https://github.com/RuJect/Snakia.git
cd Snakia
pip install -e .

🎯 Roadmap & TODO

Here's what we're working on to make Snakia even better:

• Plugin Isolation: restrict plugin access to only events and components statically defined in manifest
• Async & Multithreading: implement proper async/await support and multithreading capabilities
• Platform Support: expand platform abstraction to support more operating systems
• Random Implementations: add various random generations implementations
• TUI Widgets: create more ready-to-use TUI widgets and components
• Code Documentation: add comprehensive docstrings and inline comments
• Documentation: create detailed API documentation and tutorials

🚀 Quick Start

from snakia.core.engine import Engine
from snakia.core.loader import Meta, Plugin, PluginProcessor
from snakia.core.ecs import Component
from snakia.types import Version

# Creating a component
class HealthComponent(Component):
    value: int = 100
    max_value: int = 100

# Creating a processor
class HealthProcessor(PluginProcessor):
    def process(self, system):
        for entity, (health,) in system.get_components(HealthComponent):
            if health.value <= 0:
                print(f"Entity {entity} died!")

# Creating a plugin
class HealthPlugin(Plugin, meta=Meta(
    name="health",
    version=Version.from_args(1, 0, 0),
    processors=(HealthProcessor,)
)):
    def on_load(self): pass
    def on_unload(self): pass

# Starting the engine
engine = Engine()
engine.loader.register(HealthPlugin)
engine.loader.load_all()
engine.start()

🏗️ Architecture

Snakia is built on a modular architecture with clear separation of concerns:

📦 Examples

Health System

from snakia.core.engine import Engine
from snakia.core.ecs import Component
from snakia.core.es import Event
from snakia.core.loader import Meta, Plugin, PluginProcessor
from snakia.types import Version
from pydantic import Field

class HealthComponent(Component):
    max_value: int = Field(default=100, ge=0)
    value: int = Field(default=100, ge=0)

class DamageComponent(Component):
    damage: int = Field(ge=0)
    ticks: int = Field(default=1, ge=0)

class DeathEvent(Event):
    entity: int = Field()

class HealthProcessor(PluginProcessor):
    def process(self, system):
        # Processing damage
        for entity, (damage, health) in system.get_components(
            DamageComponent, HealthComponent
        ):
            health.value -= damage.damage
            damage.ticks -= 1
            
            if damage.ticks <= 0:
                system.remove_component(entity, DamageComponent)
            
            if health.value <= 0:
                system.remove_component(entity, HealthComponent)
                self.plugin.dispatcher.publish(DeathEvent(entity=entity))

class HealthPlugin(Plugin, meta=Meta(
    name="health",
    version=Version.from_args(1, 0, 0),
    processors=(HealthProcessor,)
)):
    def on_load(self): pass
    def on_unload(self): pass

# Usage
engine = Engine()
engine.loader.register(HealthPlugin)
engine.loader.load_all()

# Creating a player
player = engine.system.create_entity(
    HealthComponent(value=100, max_value=100)
)

# Dealing damage
engine.system.add_component(player, DamageComponent(damage=25, ticks=1))

engine.start()

TUI Application

from snakia.core.tui import CanvasChar, RenderContext
from snakia.core.tui.render import ANSIRenderer
from snakia.core.tui.widgets import TextWidget, BoxWidget, VerticalSplitWidget
import sys

class StdoutTarget:
    def write(self, text: str): sys.stdout.write(text)
    def flush(self): sys.stdout.flush()

def main():
    # Creating widgets
    title = TextWidget("Snakia TUI", CanvasChar(fg_color="cyan", bold=True))
    content = TextWidget("Welcome to Snakia!", CanvasChar(fg_color="white"))
    box = BoxWidget(20, 5, CanvasChar("█", fg_color="green"))
    
    # Layout
    layout = VerticalSplitWidget([title, content, box], "-")
    
    # Rendering
    renderer = ANSIRenderer(StdoutTarget())
    
    with RenderContext(renderer) as ctx:
        ctx.render(layout.render())

if __name__ == "__main__":
    main()
