Help description does not match actual input

[mainrs]

I wrote a small dummy sub-generator that just prints out its arguments.
If I call it using the help flag (yo efs:action -h), I get the following output:

Usage:
  yo efs:action [options] <actionFileName> <actionCreatorName>

Options:
  -h,    --help           # Print the generator's options and usage
         --skip-cache     # Do not remember prompt answers                                              Default: false
         --skip-install   # Do not automatically install dependencies                                   Default: false
  -sc,   --skip-constant  # This will skip the creation of a constant for the specific action creator.  Default: false

Arguments:
  actionFileName       Type: String  Required: true
  actionCreatorName    Type: String  Required: true

Calling it again with yo efs:action -sc filename creatorname fails, even though it is valid as seen by the help output. Option can go before arguments. The following error is printed to the console:

Error: Did not provide required argument actionCreatorName!

Another "issue" I found was that I can't use the alias defined in the options flag. It works only for --sc and not if I pass -sc (as I would have expected for a shortcut). -h works though.
Here is the generator if it is relevant:

'use strict';
const Generator = require('yeoman-generator');

class ActionGenerator extends Generator {
    constructor(args, opts) {
        super(args, opts);
        
        this.option('skip-constant', {
            alias: 'sc',
            desc: 'This will skip the creation of a constant for the specific action creator.',
            type: Boolean,
            default: false,
        });

        // this is the name of the actual action file. Files can hold more than one action.
        this.argument('actionFileName', { 
            type: String,
            required: true,
            store: true,
        });
        this.argument('actionCreatorName', { type: String, required: true });
    }

    prompting() {
        // testing
        return this.prompt([]).then(answers => {
            console.log("creating action creator " + this.options.actionCreatorName + " in file " + this.options.actionFileName + 
            ". Using constant? " + this.options["skip-constant"]);
        });
    }
}
module.exports = ActionGenerator;

Are you interested in sending a fix PR?

The relevant repository is: https://github.com/yeoman/yo

And some of those issues might be caused by https://github.com/sindresorhus/meow that we use for the CLI input parsing.

If I can fix it for sure. I will take a look! Thanks for linking the repo 😄

Same problem here. Must pass --sc instead of what the help doc says, -sc.
