# Wayshell Module System Plan

## Overview

The Wayshell Module System is designed to provide a flexible and efficient way to manage different types of modules in a Wayland environment. The system will parse configuration files and trigger actions based on specific events.

## Module Types

1. **Zone Module**: Allows defining zones and triggers for entering and exiting these zones.
2. **Layout Module**: Allows triggering actions based on the activation or deactivation of specific layout types.
3. **Focused Module**: Allows triggering actions based on focusing or unfocusing specific client types.

## Configuration Files

- **wayshell.conf**: General configuration file.
- **wayshell.modules**: Defines the modules.

## Design Constraints

- Minimize CPU usage to less than 3% when running as a daemon.
- Avoid constantly running expensive commands.

## Implementation Plan

### Phase 1: Initial Setup

1. **Parse Configuration Files**: Implement parsers for `wayshell.conf` and `wayshell.modules`.
2. **Module Initialization**: Initialize the different module types (Zone, Layout, Focused).

### Phase 2: Event Handling

1. **Zone Module**: Implement event triggers for entering and exiting zones.
2. **Layout Module**: Implement event triggers for activating and deactivating layouts.
3. **Focused Module**: Implement event triggers for focusing and unfocusing clients.

### Phase 3: Performance Optimization

1. **Efficient Parsing**: Optimize the parsing of configuration files to minimize CPU usage.
2. **Event Debouncing**: Implement debouncing for events to avoid unnecessary triggers.

### Phase 4: Testing

1. **Unit Tests**: Write unit tests for each module type.
2. **Integration Tests**: Write integration tests to ensure the modules work together correctly.
3. **Performance Tests**: Conduct performance tests to ensure the system meets the CPU usage constraints.

## Next Steps

1. Review the plan and provide feedback.
2. Proceed with the implementation based on the approved plan.
