Writing to Console [message #157004]

Fri, 14 November 2003 18:21

Eclipse User

Originally posted by: mcfaddin.us.ibm.com

I am developing a new plug-in which writes messages to stdout and stderr.
I am building the plug-in, exporting its JAR and plugin.xml files to the
eclipse\plugins directory and restarting the Eclipse environment.

However I am not seeing the output in the console viewer.

I have both options "Show when program writes to standard out" and "Show
when program writes to standard error" checked in the dialog
Window->Preferences->Debug->Console.

Is there another flag that needs to be thrown somewhere?

Try running your eclipse by starting it in a terminal using java.exe and not
javaw.exe. You will see your output on the terminal window. I don't think
that stdout normally goes to the console. I may be wrong.

I'm pretty sure that "Show when program writes to standard out" only means
"programs that are children of Eclipse"; i.e. programs launched from within
Eclipse (this does not include plugins).

I would suggest logging your message to the PDE log (plugins come with a
log(IStatus) method). Or, you could create two new OutputStreams (one for
your plugin error, and one for your plugin out) wrapped in IStreamMonitors.
And have those wrapped in an IStreamsProxy which can be connected to the
console via Console.connect(IStreamsProxy).

Check out the API for org.eclipse.debug.ui.console.

Enough people seem to ask this question, but I guess nobody has actually
raised a feature request.

You need to launch a 'program' from within your plugin. Any output your
program has to stdout / stderr will then go to the Console view. There are
articles on the Eclipse website that explain how to launch a program, see
Launching Java Applications Programmatically Darin Wright (IBM) August 26,
2003

Note that the Console is part of the Debug component of Eclipse. When I
looked I couldn't find a straightforward API call that you can use instead
of System.out.println() and thereby avoid the launching framework.
