Hello
I have a problem.
I have a commandline interpreter that i call from inside Eclipse with a
launchconfiguation. When the interpreter is called normally on a
commandline, the output is something like this:
listening on port 16104 3ee8, epoch 42112 a480
....any error messages and the like...
....input/output from interpreted program...
But when i call it from inside eclipse, and the output comes up in the
console view, the first line is missing and it looks like this:
....any error messages and the like...
....input/output from interpreted program...
Everything else is working fine. Just that one line missing?!?
Btw. when i run it in Eclipse i do it like this:
String[] commandLine = new String[] { "path/to/program", "arg1", "arg2" };
Process process = DebugPlugin.exec(commandLine, null, environment);
IProcess p = DebugPlugin.newProcess(launch, process, "name of launch");
launch.addProcess(p);
Hope anybody has any ideas...
Thanks in advance!

What stream do you write the first line to? The ProcessConsole listens
the standard streams. Nothing written to those streams should be lost.
If you want to spend time debugging this yourself I'd recommend
ProcessConsole (in org.eclipse.debug.ui plugin) as a good place to start.
It would also be a good idea to file a bug report against Platform-Debug
(and attach a test case if that's possible).
What build are you using?

Eclipse is version 3.0.1 buildid 200409161125 as far as i can tell.
I'll try out this ProcessConsole, but looking at it it's not clear to me how
to get started using it. Could you give me a quick example? I already have
the IProcess required to instantiate the ProcessConsole. What do i do now
the i have created the ProcessConsole? I have something like this:
String[] commandLine = new String[] { "path/to/program", "arg1", "arg2"};
Process process = DebugPlugin.exec(commandLine, null, environment);
IProcess p = DebugPlugin.newProcess(launch, process, "name of launch");
ProcessConsole pr = new ProcessConsole(p);
//launch.addProcess(p);
Now what?

I am not working with PlugIns, but just reading your mails (you said only
the first line isn't seen, eclipse people answered everything to stdout is
shown), please take in account of this possibility (processes
synchronization):
Maybe your Process print to stdout before eclipse start to listen to
stdout !?
Try to make some syncs between them, but you can see if that is the
problem just waiting a while in your Process before to print first line...

Tiberiu

Unless the CDT people have their own console, you are already using
ProcessConsole when you launch your application. The launching framework
will create it for you.
You may want to post to a CDT newsgroup as well. I'm only familiar with
the console framework as provided by the platform. CDT may be doing
something with the framework that I'm not aware of.

Ok. I am using the ProcessConsole then, as i am not using CDT. I am building
a plugin that is supporting a programming language called emerald. As a
part of that plugin i have a launch configuration that can launch the
emerald interpreter in the ProcessConsole. The interpreter is written in C,
thats why i mentioned that the line getting lost is a printf in a C
program. So i am not using CDT for this.
Now, is it possible, somewhat like Tiberiu mentioned, that the line is being
printed after i run DebugPlugin.exec() but before i attach it to the
ProcessConsole by calling launch.addProcess? (look at the following lines
of code, for a clearer description)
String[] commandLine = new String[] { "path/to/program", "arg1", "arg2"};
Process process = DebugPlugin.exec(commandLine, null, environment);
--> Maybe the lines get printed somewhere here where the command is executed
--> but not yet attached to the ProcessConsole?
IProcess p = DebugPlugin.newProcess(launch, process, "name of launch");
launch.addProcess(p);

Ok, adding to the weirdness... inside the program the printline normally
looks like this:
fprintf(stdout,"Emerald listening on port %d %x, epoch %d %x\n", myid.port,
myid.port, myid.epoch, myid.epoch);
but as i have told earlier this line is not shown in the ProcessConsole.
Now, if i change this line to
fprintf(stderr,"Emerald listening on port %d %x, epoch %d %x\n", myid.port,
myid.port, myid.epoch, myid.epoch);
instead and print on standard error i have this result when i run the
program normally on the commandline (it runs a program that prints out the
numbers 1-10):
Emerald listening on port 16104 3ee8, epoch 24874 612a
1 2 3 4 5 6 7 8 9 10
If i run this in eclipse, as described below, i get this instead:
1 2 3 4 5 6 7 8 9 10
Emerald listening on port 16104 3ee8, epoch 45900 b34c
where the "Emerald lis.." line is red because it's on stderr.
Why is the output switched around??
