core_daemon

My attempt of creating python daemon handler. This was written with Python 3.11

Features

• Core daemon that runs continuously and manages modules
• Interactive shell for user interaction
• Dynamic loading and unloading of modules
• Custom command execution from loaded modules
• Auto-completion for commands in the shell
• Ability to upgrade the core daemon
• Modules are loaded from an 'modules' directory

Structure

dynamic-module-manager/ ├── core_daemon.py ├── daemon_cli.py ├── modules/ │ ├── extra_commands.py │ └── http_service.py └── README.md

Getting Started

1. Start the core daemon:

python3 core_daemon.py

2. In a separate terminal, start the shell:

python3 shell.py

Usage

Once in the shell, you can use the following commands:

• list_available: List all available modules in the 'modules' directory
• load <module_name>: Load a module
• unload <module_name>: Unload a module
• list: List all currently loaded modules
• upgrade: Upgrade the core daemon (restarts the daemon in current implementation)
• Any custom commands provided by loaded modules

Use tab completion to see available commands and modules.

Creating New Modules

To create a new module:

1. Create a new Python file in the 'modules' directory
2. Define your module as a class
3. Implement at least one of these functions initialize(), shutdown(), get_commands()

See modules/extra_commands.py and modules/http_service.py for an example of how to structure a module.

Todo

• Maybe add ability to search for modules in directories set by a command

• Create module to add auth for the cli connections...

• Add error handling to core_daemon and daemon_cli...
