[Feature Request] Listing of registered keys, toggle

[nyteshade]

One thing that would be nice in our production environments is to be able to toggle on debug values during runtime without

• Knowing which keys the developer used in the code
• Restarting the server in question

It seems like this could be circumvented by exposing, via a method, the list of debug keys supplied in the form of require ('debug')(debugKey). Then, of course, a call to enable, if it does what it sounds like it does should start the logs flowing. The biggest issues being without looking through the code its hard to know what to even enable on the command line, the hard way.

It could also be enhanced to allow supplying a description such as

require('debug')(
  'ui:login',
  'Calls with this signature log the workings of the login process'
)
require('debug')(
  'ui:login:trace',
  'Calls with this signature log normally too verbose workings of the login process'
)

This way when doing something like require('debug').list() we might get a response such as:

[
  {key:'ui:login', desc:'Calls with this signature log the workings of the login process'},
  ...
]

If nobody else has provided a working, backwards compatible, solution to dynamic enabling and disabling of these log calls, I'll take a look myself.

This project would solve both your problems: https://github.com/bdentino/redebug

But yah +1. It's sorta hacky, and it would be great to see this in core.
