Allow passing custom logger

[sajal]

Currently setting router.LogRequests = true , the requests logs are printed to stderr using default format. But I would like some way to pass a custom logger, example: logrus . Most logging implementations can be abstracted to a simple interface.

If provided use it, otherwise use the default behavior.

Hi @sajal sorry for the late reply, I did some changes but after doing some tests I think is better to add the logger in a middleware.

In any case, I will try to see what could I do, mainly because the logger may need a custom responseWriter that depending on the logger it should be adapted.

Any ideas are more than welcome.

@sajal What do you think about this: https://github.com/nbari/violetear/blob/master/violetear.go#L69

Basically, ask for a function so that you can pass the response writer:

// Logger
Logger func(*ResponseWriter, *http.Request)

The default one to use is this one: https://github.com/nbari/violetear/blob/master/logger.go

Please give a try and let me know what you think.

Thats useful. Looks like my code can use different logging paths based on status, etc...

I still doing some improvements, for the idea is that based on your logger you can manipulate the as required, the function needs to be:

func logger(ww *ResponseWriter, r *http.Request) {}

And from there you can take or use any of the ResponseWriter, or the Request.

I will document this later, any ideas are more than welcome.
