[Gambas-user] gb.logging API change

[Sebastian Kulesz]

So, i have changed the API again. Now, each logger has an associated array
of handlers, each of which takes care of storing the data in a specific
way. Right now, the component only includes a console handler to output
logs to stdout or stderr. And a file handler to output logs to files.
Each logger can have an arbitrary amount of loggers, and they even can be
shared across loggers.
This way a several loggers can output to the same file by sharing a
handler, or a logger can output to several files, all depending on the
logging level.

Take a look at the following example:
<---------
  Dim aHandler, bHandler As LogHandler

  Dim bLogger As Logger

  aHandler = New ConsoleHandler(ConsoleHandler.STDOUT)
  bHandler = New FileHandler("~/Desktop")

  bLogger = New Logger(Null, aHandler)

  bLogger.Begin()

  bLogger.Log("This goes to the stdout stream")

  bLogger.addHandler(bHandler)
  bHandler.Open

  bLogger.Log("I can read this in the console or at a file stored in my
Desktop folder.")

  Logger.Log("There is no need to use handlers. You can use the Logger
anonymously.")
---------->

bLogger outputs to 2 locations simultaneously. If you want, both handlers
could use a different level of severity ;)

I will be adding some more handlers in the following days.

Enjoy!
