Re: Capturing sysin and sysout-FIXED

[Jiger Patel]

Yo!! I have fixed this apparently. I posted this message after three days of 
dilema and fixed it in the next 5 minutes :) After as bit of code here and 
there I seem to finally put all the pieces together and both out and err 
seems to be captured except for one thing that JythonEngine does not set the 
Message of the error in the Exception but displays the message in 
bsfexception.getTargetException().toString()!!! and Javascript/Beanshell 
puts the proper error message but I guess that all the Engines could be made 
standard with this respect.

On the other note the Plugin seems to have fixed/introduce two major 
enhancements and on my way to releasing a 0.2 release soon :)

Thanks for all your help,
Jiger

Subject: Capturing sysin and sysout
Date: Wed, 04 Jun 2003 11:46:09 +0530

Hi,
   Is there someway to capture the sysout and sysin of any BSF Scripting 
engine. In my application I want to capture the output of a "print" or a 
"System.out.println" or any "console" out and show it on the GUI textarea. 
"Beanshell" and "javascript"(see note below) "seem" to be working but 
jython is playing some game. I tried redirecting System.out to a 
ByteArrayBuffer in the following way

ByteArrayOutputStream byOut = new ByteArrayOutputStream();
PrintStream  pOut = new PrintStream(byOut);
PrintStream oldStream = System.out;
System.setOut(pOut);
loadBSFManager(view);
bsfmanager.exec(bsfpanel.getCurrentLanguage(),filename,1,1,script);
pOut.flush();
printOutput(byOut.toString());
System.setOut(oldStream);
pOut.close();
pOut=null;
byOut = null;
But yet jython's "print" statement comes on the System.out logs but not in 
the byOut above. Other languages seem to work fine. Except Javascript which 
returns an org.mozilla.javascript.UndefinedFunction object in the eval but 
that is a for some other mail.

So can anyone suggest someway as to how to capture the sysouts and sysins 
in some language independent way or can BSF add Input and Output stream 
params to the exec/eval methods which the scripting engines can then 
enforce in the language dependent way. Or maybe some method like setIn and 
setOut in the BSFManager for the streams to be used by the scripting 
engines when they are initiailised.

Any ideas?

Thanking you,
Jiger.
