Hola Nico,
The "standard output" in most Smalltalks is usually considered the Transcript. You may use it in a method like this: >>log: aString " Write aString to the transcript streamer " Transcript cr; show: TimeStamp current; space; show: aString is that useful to you?

if you refer to kind of UNIX stdout then you should try OSProcess I gues...

Hi Hernan, I am know the Transcript and it not what I need. I need to integrate some my Smalltalk stuff other application, to more specific, I have an application that will call Smalltalk to perform certain operations and then the calling application needs to know the result of the operations. I could implement this using a file, but I want to avoid files if possible, that is why I want to write to the standard output.

You have to add a new primitive I think ...

I don't know why I remember some Cog extensions in StandardFileStream or something like that that could directly write to the standard output...but maybe I am just dreaming. Anyway wouldn't OSProcess do the job?

Yes of course. Specifically for debugging support, see the #trace, #trace: and #debug: methods. Handy if you are trying to debug something that might drop you into an emergency evaluator. It also is running from the VM, so it avoids timing confusion related to Smalltalk process scheduling and flushing the ouput stream. Dave |

Hi, I am trying to follow the advice using OSProcess but I get an error message saying: "process accessor module not available"
I am running on Win7, could that be the problem?

Yes, the OSProcess plugin is not distributed with Windows VMs, so
this will not work on Windows.

I saw this items sent by Marcus previously in this thread:
Their status is "FixedWaitingToBePharoed", I would like to work on them so, what should I do? try to do a file in and make it run? is there any documentation about how to "Pharoed code" ?

Yes. The idea is to check if the fix / enhancement makes sense and if yes, make a changeset / SLICE for the latest Pharo. > is there any documentation about how to "Pharoed code" ? > No... I think there is no general valid strategy and the system is so large and everything is different. -- Marcus Denker -- http://www.marcusdenker.de INRIA Lille -- Nord Europe. Team RMoD. |
