[Question] Command pattern matching and arg parsing

[gzcharleszhang]

Suppose I want to build a command such as .emoji add <imageUrl> where . is the prefix and <imageUrl> is the only argument. Since default handling doesn't support commands with a space in its name, so I am using regex for command matching. However, the only one I know how to parse the argument is through using a regex capturing group like so:

patterns: [/^.emoji add (.*)/],
args: [
  {
    key: 'imageUrl',
    prompt: 'specify the emoji you want to add',
    type: 'string',
    ...
  }
],

To get the args I can only do args[1] which is the capturing group I specified in the regex. Is there a way to use both patterns matching and leverage Commando's built-in argument parsing/validation, so that I can do args.imageUrl or enable prompts when an argument isn't specified like in commands with default handling?

What you could do is make an argument for the "add". Depends if you want to make commands like edit and remove

const { Command } = require('discord.js-commando');

module.exports = class MeowCommand extends Command {
    constructor(client) {
        super(client, {
            ...
            args: [
                {
                    key: 'action',
                    prompt: 'specify the action you want to peform',
                    type: 'string',
                    oneOf: ['add', 'remove'],
                },
                {
                    key: 'imageUrl',
                    prompt: 'specify the emoji you want to add',
                    type: 'string'
                },
            ],
        });
    }
    run(message, { action }) {
        switch (action) {
            case 'add':
                //code
                break;
            case 'remove':
                //code
                break;
        }
    }
};
