[gecode-users] Output control for the Script class

[Christian Schulte]

Hi Andrea,

 

If you send me the patches, I can have a look. I am not that sure because
there is always the option to not use the driver but use a search engine
directly.

 

Cheers

Christian

Subject: [gecode-users] Output control for the Script class

 

Hi,

 

I'am using Gecode for a project at work (I'am using Script class) and I
needed to separate Gecode message (timing, statistics etc..) from solutions.
That's because solutions "goes out" in a certain format that another process
have to decode, so I cannot mix solutions with Gecode message.

 

The simplest solution I found was to change cout to clog everywhere in
ScriptBase::run, everywhere BUT when calling ex->print() which print the
solution. This is enough to have Gecode messages to standard log and
solutions to standard output, and now I can redirect them separately.

 

I would like to have this kind behavior on future releases of Gecode.
Flatzinc has already some options that do something like that (-s and -o, I
think), I want to implement something similar and send some patches if you
agree (it's pretty simple from what I see).

Tell me what you think about it.

 

Cheers.
