Custom logger could affect the auto-generated help

[yuhwan]

background

I'm using the logdown module as my custom logger, which is one of winston-compatible loggers. This module provides a functionality to attach a tiny emoji and a custom prefix to every messages like below.

const logger = require('logdown')('caporal:');
logger.info('this is a test message');

ℹ caporal: this is a test message

problem

The problem is the custom logger attaches the meta data(i.e., emoji and prefix) into the help instructions as well. This is because the help.js utilizes program.logger object to print out the help instructions. So, when I set my custom logger, the help instructions are like below.

ℹ caporal: 
   caporal test 1.0.0 
     
   USAGE

solution idea

The logdown logger may be not the only one that has this problem. I think the help instruction message should be independent with custom logger because it's auto-generated by Caporal.js. How about just using the default console.log function to print out the help instructions?

Please let me know there is any point that I misunderstood or missed 👍
