Thanks James and Laurent,<br>
<br>
Actually this question was more to learn is it was possible. I<br>
remember a post about keeping or not comment in the source code...<br>
<br>
To be more precise, it's for log output of the inference system<br>
(<a href="http://nars.seasidehosting.st/" target="_blank">http://nars.seasidehosting.st/</a>). In each step, there can be something<br>
like 10 lines processes depending on entities are infered. The thing<br>
is this log output chunks are mixed in the code in several places. I<br>
could maybe use a better trigger mechanism like sending a signal with<br>
the entity in question, but still, there will be this message sent (or<br>
the test). I used stream and it seems ok (regarding performance), just<br>
wanted to know if we could deactivate some portion of code as<br>
everything seems possible here ;). I'll remind the subclass tip<br>
though.</blockquote><div><br><br> Hi Cédrick.<br><br>For this sort of thing, I usually use:<br><br>self assert: [some code].<br><br>When you put your code into production, you can make the implementation of Object>>assert: be a "^self", which has very little overhead.<br>
<br>You could apply the same to logging, by implementing a similar method:<br><br>self log: [ 'Some error occured.' ]. " The return value of the block is logged.
