### Shellminator Core and Commander Interface (C++)

Source: https://www.shellminator.org/html/205_commander_cowsay_page

This snippet shows the core setup for the Shellminator project. It includes necessary headers, defines constants for ASCII art, initializes a Commander object, and sets up the system command tree. The `setup` function initializes the serial communication, clears the terminal, and attaches the commander interface, while the `loop` function continuously updates the shell. The `cowsay_func` implements the cowsay-like functionality.

```cpp
#include "Shellminator.hpp"
#include "Shellminator-Commander-Interface.hpp"
#include "Commander-API.hpp"
#include "Commander-Arguments.hpp"

    shell.attachCommander( &commander );
    // Initialize shell object.
    shell.begin( "arnold" );
}

// Infinite loop.
void loop(){
    // Process the new data.
    shell.update();
}

bool cowsay_func(char *args, CommandCaller* caller ){
    char textBuffer[ 30 ];
    int i;

    // The text argument is place dependent but optional.
    // It has to be the first argument when it is given.
    Argument text( args, 0 );

    // These are the optional flags for the command.
    Argument tired_flag( args, 't', "tired" );
    Argument wink_flag( args, 'w', "wink" );

    // Try to find if these flags can be found in the command.
    tired_flag.find();
    wink_flag.find();

        for( i = strlen( textBuffer ) + 2; i > 0 ; i-- ){
            caller -> print( '-' );
        }
    }
    // Draw the default text.
    else{
        caller -> print( "booo >\r\n ------" );
    }

    caller -> println();
    caller -> print( cow_top );

    // The eye drawing has a priority in case multiple flags are given.
    // Check each flag from top priority and draw the corresponding eyes.
    if( tired_flag.isFound() ){
        caller -> print( tired_eyes );
    }
    else if( wink_flag.isFound() ){
        caller -> print( wink_eyes );
    }
    else if( greedy_flag.isFound() ){
