Template for interactive program

Overview

Template for interactive programs, which will be written in V.

Includes a small amount of built-in features:

• Help message printing (just help and also help <command>)
• Aliases (for example you can use q instead of quit)

Command creating

To create a new command follow the steps:

1. Create structure based on Command interface like existing one:

struct CommandEcho {
mut:
	name string = 'echo'
	description string = 'Prints the given text to the console.'
	aliases []string
	cmdhandler &CommandHandler
}

2. Add print_help and run functions to your structure

3. Add created structure to CommandHandler (init function):

fn (mut c CommandHandler) init() {
	// Put new commands here
	c.add_command(CommandEcho{ cmdhandler: &c })
	c.add_command(CommandQuit{ cmdhandler: &c })
	c.add_command(CommandHelp{ cmdhandler: &c })
}
