How can I remove text which "println" in controlP5 shows?

in Contributed Library Questions • 3 years ago

Hey.

After starting an applet ( play button) I'm getting some information from controlP5.

Is there a way to remove it somehow just by putting some code into my applet...?

Or could someone remove that text and compile necessary file(s?) again please?

...

System.out.println("### INFO you are using renderer "

      + _myApplet.g.getClass().getName()

      + "\n"

      + "to draw controlP5 you have to call the controlP5.draw() method inside of\n"

+ "your processing sketch draw() method.");
...

we had that discussion some weeks ago.
As far as i remember there was no way to clear the console.
But you can just call a bunch of empty println() to remove it.

but why does it bother you that much ?

Solution: Dont use ControlP5. Its not that hard to make your own sliders, buttons and/or textfields.

That's not a 'solution'... The point is that there's no good reason I can think of to want to clear the console, except perhaps for clarity (in which case a few empty lines are adequate). It's there for debugging purposes and shouldn't be relied on for final output as it won't be visible in an exported sketch...

@snallow - Why do you want this information removed from the output? Are you trying to cover up the fact you're using the controlP5 library?

why can't simply compile file(s) again where " ### INFO you are using..." appears...?

I don't want to clear the whole console, because I need to see debugging any my own things.

@blindfish - of course not. I'm happy Andreas make it, but that INFO is just to long....

it's just annyoing, covers some of my information and makes them not so easy to see,

I'm using console for displaying some coordinates (and they do change all the time...)

Surely the controlP5 stuff is only displayed at the beginning of the output?

Are you trying to compare the coordinates over time? In which case you might be better off writing them to a separate log file rather than trying to use the console window; and that way you separate the data from other console output and can easily import it into something like Excel (assuming that would be useful). Also, IIRC (and someone please correct me if I'm wrong) you can run into performance/memory issues if you write too much to the console; which is likely to happen eventually if you run println every frame...

And if you're just interested in the current value it might be simpler to just draw it to the screen.

Again, it's one of these things where the Processing tool & community would have been doing much better to adhere to some more standard Java patterns instead of trying so hard to hide its parent...

For the main tool, instead of a simple println(), the best solution would have been to use a logging framework (e.g. the one in the java.util.logging package to avoid any 3rd party dependencies) and then create PApplet shortcuts for the different log levels (e.g. debug(), warning(), info() etc.)

The presence of these would also have encouraged library developers to utilize these and we would have been able to adjust the log levels (granularity) of different loggers based on which package they're based in...

So if ControlP5 would use such a logger, you could mute it entirely by just saying:

Logger.getLogger("controlp5").setLevel(Level.OFF);

The other thing you might consider is to write your own stuff to the system's error stream, which will also show up in the console (but in red) and so it will be visually easier to separate (Wrap it in a method if you want to type less):

System.err.println("foo");

Hi,

I found out that it's possible to redirect the console output.

println("I am here for the first time.");
try {
String FILE = sketchPath+"\\console.txt";
FileOutputStream outStr = new FileOutputStream(FILE, true);
PrintStream printStream = new PrintStream(outStr);
System.setOut(printStream);
System.setErr(printStream);
println("I am somewhere...");
}
catch (IOException e) {
System.err.println("Error! Check path, or filename, or security manager! "+e);
}
println("I AM HERE!");

I am looking for a way to make the stream writing Byte, so that all the other info get filtered. Because when you drag the processing frame and open console.txt, you see allot of info you don't want to see.

Greetings, Dipperson
