# Command Parser

A command parser initially made for quickly making discord bots, but works as a standalone parser too.

Your commands are expected to inherit from the Command class or implement the ICommand interface (requires slightly more work given that interfaces don't provide default implementations for the required functionality). The latter is required if you for any reason need to extend your own superclass of command/component. See examples for more about extending/implementing.

Example projects that implement the parser:  
[Discord music bot by me](https://git.corgi.wtf/Navy.gif/music-bot)  
[My webserver template](https://git.corgi.wtf/Navy.gif/webserver-framework) (uses parser for CLI and listening for input on stdin)

**Example usage**  
```js

const commands: Command[] = [
    new Command({
        name: 'ping',
        options: [
            {
                name: 'respond',            //
                type: OptionType.BOOLEAN,   // Boolean type expects the parser to have some kind of string -> boolean resolver, see the resolver interface for which methods are expected
                required: true,             // Will throw error if not provided
                defaultValue: true,         // The value that will be given back if no value is given, or if option is required but not provided
                flag: true                  // The parser will look for the option in the "--respond value" form
            }
        ]
    })
]; // Command definitions

const parser = new Parser({commands, prefix: ''}); // Empty prefix
const parsed = await parser.parseMessage('ping --respond');

/**
 * Parsed will be an object cotaining properties args, command, subcommand, and subcommandgroup
 * the args property is an object of the given options mapped by their names, e.g.
 * {
 *   respond: {
 *     ... properties,
 *     value: true
 *   }
 * }
 * 
*/

```

Some of the option types have built-in parsers (e.g. numbers, strings), but others will require the resolver implementation, and in some cases CommandOption extensions.
