## ⚙️ Core
### Engine
The central component of the framework that coordinates all systems:
```python
from snakia.core.engine import Engine
engine = Engine()
# Systems:
# - engine.system - ECS system
# - engine.dispatcher - Event system
# - engine.loader - Plugin loader
engine.start() # Start all systems
engine.stop() # Stop all systems
engine.update() # Update systems
```
## 🎯 ECS System
Entity-Component-System architecture for creating flexible and performant applications.
### Component
Base class for all components:
```python
from snakia.core.ecs import Component
from pydantic import Field
class PositionComponent(Component):
x: float = Field(default=0.0)
y: float = Field(default=0.0)
class VelocityComponent(Component):
vx: float = Field(default=0.0)
vy: float = Field(default=0.0)
```
### Processor
Processors handle components in the system:
```python
from snakia.core.ecs import Processor, System
class MovementProcessor(Processor):
def process(self, system: System) -> None:
# Get all entities with Position and Velocity
for entity, (pos, vel) in system.get_components(
PositionComponent, VelocityComponent
):
pos.x += vel.vx
pos.y += vel.vy
```
### System
Entity and component management:
```python
# Creating an entity with components
entity = system.create_entity(
PositionComponent(x=10, y=20),
VelocityComponent(vx=1, vy=0)
)
# Adding a component to an existing entity
system.add_component(entity, HealthComponent(value=100))
# Getting entity components
pos, vel = system.get_components_of_entity(
entity, PositionComponent, VelocityComponent
)
# Checking for components
if system.has_components(entity, PositionComponent, VelocityComponent):
print("Entity has position and velocity")
# Removing a component
system.remove_component(entity, VelocityComponent)
# Deleting an entity
system.delete_entity(entity)
```
## 📡 Event System (ES)
Asynchronous event system with filter and priority support.
### Event
Base class for events:
```python
from snakia.core.es import Event
from pydantic import Field
class PlayerDiedEvent(Event):
player_id: int = Field()
cause: str = Field(default="unknown")
ttl: int = Field(default=10) # Event lifetime
```
### Handler
Event handlers:
```python
from snakia.core.es import Handler, Action
def on_player_died(event: PlayerDiedEvent) -> Action | None:
print(f"Player {event.player_id} died from {event.cause}")
return Action.move(1) # Move to next handler
```
### Filter
Event filters:
```python
from snakia.core.es import Filter
def only_important_deaths(event: PlayerDiedEvent) -> bool:
return event.cause in ["boss", "pvp"]
# Using a filter
@dispatcher.on(PlayerDiedEvent, filter=only_important_deaths)
def handle_important_death(event: PlayerDiedEvent):
print("Important death occurred!")
```
### Dispatcher
Central event dispatcher:
```python
from snakia.core.es import Dispatcher, Subscriber
dispatcher = Dispatcher()
# Subscribing to an event
dispatcher.subscribe(PlayerDiedEvent, Subscriber(
handler=on_player_died,
filter=only_important_deaths,
priority=10
))
# Decorator for subscription
@dispatcher.on(PlayerDiedEvent, priority=5)
def handle_death(event: PlayerDiedEvent):
print("Death handled!")
# Publishing an event
dispatcher.publish(PlayerDiedEvent(player_id=123, cause="boss"))
```
## 🔌 Plugin System
Modular system for loading and managing plugins.
### Plugin
Base class for plugins:
```python
from snakia.core.loader import Meta, Plugin, PluginProcessor
from snakia.types import Version
class MyProcessor(PluginProcessor):
def process(self, system):
# Processor logic
pass
class MyPlugin(Plugin, meta=Meta(
name="my_plugin",
author="developer",
version=Version.from_args(1, 0, 0),
processors=(MyProcessor,),
subscribers=()
)):
def on_load(self):
print("Plugin loaded!")
def on_unload(self):
print("Plugin unloaded!")
```
### Meta
Plugin metadata:
```python
from snakia.core.loader import Meta
from snakia.core.es import Subscriber
meta = Meta(
name="plugin_name",
author="author_name",
version=Version.from_args(1, 0, 0),
processors=(Processor1, Processor2),
subscribers=(
(EventType, Subscriber(handler, filter, priority)),
)
)
```
### Loader
Plugin loader:
```python
from snakia.core.loader import Loader
loader = Loader(engine)
# Registering a plugin
loader.register(MyPlugin)
# Loading all plugins
loader.load_all()
# Unloading all plugins
loader.unload_all()
```
## 🎨 TUI System
System for creating text-based user interfaces.
### Widget
Base class for widgets:
```python
from snakia.core.tui import Widget, Canvas, CanvasChar
from snakia.core.rx import Bindable
class MyWidget(Widget):
def __init__(self):
super().__init__()
self.text = self.state("Hello World")
self.color = self.state(CanvasChar(fg_color="red"))
def on_render(self) -> Canvas:
canvas = Canvas(20, 5)
canvas.draw_text(0, 0, self.text.value, self.color.value)
return canvas
```
### Canvas
Drawing canvas:
```python
from snakia.core.tui import Canvas, CanvasChar
canvas = Canvas(80, 24)
# Drawing text
canvas.draw_text(10, 5, "Hello", CanvasChar(fg_color="blue"))
# Drawing rectangle
canvas.draw_rect(0, 0, 20, 10, CanvasChar("█", fg_color="green"))
# Filling area
canvas.draw_filled_rect(5, 5, 10, 5, CanvasChar(" ", bg_color="red"))
# Lines
canvas.draw_line_h(0, 0, 20, CanvasChar("-"))
canvas.draw_line_v(0, 0, 10, CanvasChar("|"))
```
### CanvasChar
Character with attributes:
```python
from snakia.core.tui import CanvasChar
char = CanvasChar(
char="A",
fg_color="red", # Text color
bg_color="blue", # Background color
bold=True, # Bold
italic=False, # Italic
underline=True # Underline
)
```
### Renderer
Screen rendering:
```python
from snakia.core.tui import RenderContext
from snakia.core.tui.render import ANSIRenderer
import sys
class StdoutTarget:
def write(self, text: str): sys.stdout.write(text)
def flush(self): sys.stdout.flush()
renderer = ANSIRenderer(StdoutTarget())
with RenderContext(renderer) as ctx:
ctx.render(widget.render())
```
### Ready-made Widgets
```python
from snakia.core.tui.widgets import (
TextWidget, BoxWidget,
HorizontalSplitWidget, VerticalSplitWidget
)
# Text widget
text = TextWidget("Hello", CanvasChar(fg_color="red", bold=True))
# Box widget
box = BoxWidget(10, 5, CanvasChar("█", fg_color="yellow"))
# Splitters
h_split = HorizontalSplitWidget([text1, text2], "|")
v_split = VerticalSplitWidget([h_split, box], "-")
```
## ⚡ Reactive Programming (RX)
Reactive programming system for creating responsive interfaces.
### Bindable
Reactive variables:
```python
from snakia.core.rx import Bindable, ValueChanged
# Creating a reactive variable
counter = Bindable(0)
# Subscribing to changes
def on_change(event: ValueChanged[int]):
print(f"Counter changed from {event.old_value} to {event.new_value}")
counter.subscribe(on_change)
# Changing value
counter.set(5) # Will call on_change
counter(10) # Alternative syntax
```
### AsyncBindable
Asynchronous reactive variables:
```python
from snakia.core.rx import AsyncBindable
async_counter = AsyncBindable(0)
async def async_handler(event: ValueChanged[int]):
print(f"Async counter: {event.new_value}")
await async_counter.subscribe(async_handler, run_now=True)
await async_counter.set(42)
```
### Operators
```python
from snakia.core.rx import map, filter, combine, merge
# Transformation
doubled = map(counter, lambda x: x * 2)
# Filtering
even_only = filter(counter, lambda x: x % 2 == 0)
# Combining
combined = combine(counter, doubled, lambda a, b: a + b)
# Merging streams
merged = merge(counter, async_counter)
```

🚫 Codacy found a high ErrorProne issue: expected '(' (F999)

The issue reported by the Prospector linter is due to the incorrect syntax used for the type parameters in the function definition. In Python's type hinting, you cannot use square brackets [] for defining type variables; instead, you should use parentheses () with the TypeVar function from the typing module.

To fix the issue, you need to change the definition of the cond function to use TypeVar for the type parameters. Here's the single line change needed:

def cond(P, T, F)(condition: Callable[P, bool], if_true: Callable[P, T], if_false: Callable[P, F]) -> Callable[P, T | F]:

🚫 Codacy found a high ErrorProne issue: invalid syntax (F999)

The issue arises from the use of generics in the class definition. The syntax Readonly[T](Property[T]) is incorrect in Python, as the use of generics requires the Generic base class from the typing module. To fix this, you need to inherit from Generic[T] in addition to Property[T].

Here's the code suggestion to fix the issue:

class Readonly(Property[T], Generic[T]):
