// version v1.2

// I like things to be easy.
|
|
//
|
|
// this means all the log settings are in one place. it should allow
|
|
// things to be over-ridden externally to the library
|
|
// but still allow command line --args to pass debugging settings
|
|
//
|
|
// I also have a generic sleep() and exit() in here because it's simple
|
|
//
|
|
// Usage:
|
|
//
|
|
// log("something", foo, bar)
|
|
// var DEBUG bool = true
|
|
// log(DEBUG, "something else", someOtherVariable) # if DEBUG == false, return doing nothing
|
|
// log(SPEW, "something else", someOtherVariable) # this get's sent to spew.Dump(). Very useful for debugging!

I've spent, am spending, too much time thinking about 'logging'. 'log', 'logrus', 'zap', whatever.
|
|
I'm not twitter. i don't give a fuck about how many nanoseconds it takes to log. Anyway, this
|
|
implementation is probably faster than all of those because you just set one bool to FALSE
|
|
and it all stops.
|
|
Sometimes I need to capture to stdout, sometimes stdout can't
|
|
work because it doesn't exist for the user. This whole thing is a PITA. Then it's spread
|
|
over 8 million references in every .go file. I'm tapping out and putting
|
|
it in one place. here it is. Also, this makes having debug levels really fucking easy.
|
|
You can define whatever level of logging you want from anywhere (command line) etc.
|
|
|
|
log() # doesn't do anything
|
|
log(stuff) # sends it to whatever log you define in a single place. here is the place
