🎛️ Context-Driven

By adding LogiViewContext as a method argument, you enable bidirectional control based on UI lifecycle.

An advanced implementation pattern where a single method describes not just "execution (Fire)" but also "state synchronization (Sync)" and "change application (Update)".

📝 Implementation Example: Stateful Numeric Control

Define a return value and specify LogiViewContext as the second argument.

int _integer = 10;

[LogiButton("Advanced Counter")]
int OnUpdateCounter(int input, LogiViewContext context)
{
    // 1. Processing on user input
    if (context == LogiViewContext.ValueChanged)
    {
        // Data validation and logging
        _integer = Mathf.Clamp(input, 0, 100);
        Debug.Log($"[Logify] Value changed: {_integer}");
    }
    // 2. Processing on rendering/initialization
    // Always synchronize UI display with current field value (_integer).
    return _integer;
}

🔄 Lifecycle Loop

The method is called in three contexts aligned with UI updates.

Context	Timing	Role
Init	Initial creation	Set default values and build cache.
Repaint	Rendering update	Return current value.
ValueChanged	Input detection	Apply user changes to internal variables (Setter).

📖 Practical Recipe: Input, Execute, Clear Coordination

Debug menus frequently require operations like "enter string, submit, and clear input field after submission". Context-driven processing makes this extremely concise.

Implementation Example: Debug Message Submission

using UnityEngine;
using Logify;

public sealed class MessageDebugger : MonoBehaviour
{
    string _currentMessage = string.Empty;

    // 1. Message input field
    // Through Repaint context, UI automatically clears when internal variable (_currentMessage) becomes empty
    [LogiInput("Message to Send")]
    string OnUpdateMessage(string input, LogiViewContext context)
    {
        if (context == LogiViewContext.ValueChanged)
        {
            _currentMessage = input;
        }
        return _currentMessage;
    }

    // 2. Send button
    // Processes on button click, then resets internal variable
    [LogiButton("Send & Clear", "Send")]
    void Send()
    {
        if (string.IsNullOrEmpty(_currentMessage))
        {
            return;
        }
        Debug.Log($"[Server] Sending: {_currentMessage}");
        // Simply clearing internal variable automatically syncs UI through Input-side Repaint
        _currentMessage = string.Empty;
    }

    void Awake() => Logi.Register(this, "Network Debug").AddTo(this);
}
