feat(#100): show CMD for --execute if --show-cmd is added

[AlejandroSuero]

With these changes, if the user adds the flag --show-cmd it will print the executed command when using --execute "<cmd>".

Demo:

show-cmd-flag-demo.mp4

Closes #100

This is perfect! 😍

I added this locally to better showcase the command:

If you think is a good idea and want to add it, making tweaks to colours if needed too.

How about defining the --show-cmd flag as a string instead of a boolean? When --show-cmd is passed as an empty string (e.g., --show-cmd=""), it could display the command executed by --execute. If a custom string is provided, that string could be shown instead. This would allow for more flexibility, such as adding icons, custom prompts, or styling.

Thanks for the feedback @almas1992, I'll try and change it this weekend and see how it turns out.

[AlejandroSuero]

@almas1992 This is how it turned out when I change it to a string, the thing is, that if you use it as string, when omitted, it will always show by default, unless we get an option like like --show-cmd="y" to avoid showing it always.

The problem with string is that if you use it like freeze -x "eza -la" --show-cmd -c full it will take -c as the string input for --show-cmd.

The other solution would be to have a flag like --show-cmd.title to use it as the title when --show-cmd it's included.

[almas1992]

@AlejandroSuero The string flag indeed has this issue; it cannot be passed without a value. To resolve this, you can either add a separate .title flag as you suggested, or manually iterate through os.Args to handle the parameters before passing them to kong for parsing.
