CapsuleCore shellback

Shellback is a robust, architecturally-agnostic Python library designed to bridge terminal environments (Bash, CMD, PowerShell) with Python scripts. It provides a clean, decoupled abstraction layer to execute system commands while maintaining persistent session state and cross-platform compatibility.

Built with Hexagonal Architecture (Ports and Adapters) principles, Shellback ensures that your domain logic remains independent of the specific shell or operating system being used.

Usage

from cc_shellback_kit.capsule import Bash
from cc_shellback_kit.core import Command, SessionContext
from cc_shellback_kit.observers import ConsoleLogObserver

# 1. Configuramos el observador para ver la actividad en consola
observer = ConsoleLogObserver()

# 2. Iniciamos la Shell usando el manejador de contexto (with)
with Bash(observer=observer) as shell:
    
    # --- EJECUCIÓN DE COMANDOS EXTERNOS ---
    # Creamos un comando simple: 'ls -la'
    cmd_list = Command("ls").add_args("-la")
    result = shell.run(cmd_list)
    
    if result.is_success():
        print(f"Archivos encontrados:\n{result.standard_output}")

    # --- MANEJO DE ESTADO (VIRTUAL BUILT-INS) ---
    # Cambiamos de directorio (esto afecta al SessionContext, no solo al proceso)
    shell.run(Command("cd").add_args("/tmp"))
    
    # Verificamos el cambio ejecutando un 'pwd'
    shell.run(Command("pwd"))

    # --- VARIABLES DE ENTORNO ---
    # Exportamos una variable que persistirá durante este bloque 'with'
    shell.run(Command("export").add_args("APP_STAGE=development", "DEBUG=true"))
