Hi guys (German).
Today I needed to add some real log to something I am developing and I found
that SimpleLogger missed those functionalities I was needing. So...I
implemented them. It is 3 hours effort, so don't expect too much. But I just
wanted to shared with you in case you need it.
What I did basically is to define SimpleLogger like the public API. But
then, this class delegates to a LoggerStrategy. I created the following
implementations: TranscriptLoggerStrategy, NullLoggerStrategy,
FileLoggerStrategy and FixesFileNameLoggerStrategy. In addition, I created
a superclass for them, marking the API with SimpleLogger. This class is
LoggerStrategy.
So, now you can:
- Enable and disable easily the logging (thanks to NullLoggerStrategy).
- Change on runtime WHERE or HOW to log (just change the strategy).
- Be able to write into a File, a Transcript, a FixedFileName, or nothing.
- Extend to you own strategy (FileAppendLoggerStrategy??
SocketLoggerStrategy? etc...)
I did these changes today morning so I didn't have time to write tests nor
class comments. However, I wrote some class side example methods in
SimpleLogger.
Finally, for my own projects I want:
- to use a FixedFileName (very similar to the way PharoDebug.log is used).
- to only do "self log:" in my classes.
The solution I did is that somewhere (maybe in a class of your project or
maybe in a special class that holds this) in a class side variable I hold a
Singleton with the Logger. So that you can always do for example:
MyAppLogger logger log: 'zaraza'.
And finally, I implemented Object >> log: (with category *MyAppPackage)
log: anObject
MyAppLogger logger log: anObject.
With this, anywhere in the classes of my app I can do: self log:
'something'.
The code is temporally commited in http://www.squeaksource.com/Marea
German: if you think I should commit directly to SimpleLogger repo, just let
me know. In addition, be completely free to change it as you want and commit
it there too.
Cheers
mariano
