Issue with System.out.print

[qcsoftware513]

Small issue...when using System.out.print() I do not see the output in the console until a new line is printed. In the below example, I don't see abc print out until after the sleep command completes.

public class NBTest { @SuppressWarnings("unused") private static final String svnid = "$Id$";

public static void main(String[] args) { System.out.println("123456"); System.out.print("abc"); try { Thread.sleep(5000); } catch(InterruptedException ex) { ex.printStackTrace(); } System.out.println("123"); } }

This is causing issues because the System.out.print in my application displays a prompt and then the program waits for user input. I can type in the input and everything works, but then i don't see the prompts which can be confusing. Maybe I am missing a setting.

Thanks!

Try using System.out.flush() after System.out.print().

System.out.println() includes the call to flush(). print() doesn't.

That did not help. Same behavior.

I don't output anything before receiving a line ending to analyze a full line if something has to be turned into a link. I can't really remember but I think Gradle also won't send it back before a new line is emitted (not sure about this last one though).

[qcsoftware513]

Any thoughts as to how I might get around this?

[kelemen]

I think currently the only way to get around this is to start Gradle from the terminal (even if it is the terminal of NB). I have checked and it seems that Gradle does send back the output so it is solvable on my side, assuming I do something with the problem that then I can't easily analyze a line to provide links. I could provide some timeout (configurably) but I guess that would still be very annoying. Or I could provide a configuration which disables analyzing lines (and you won't get links in the output window) but would see the output immediately. What would be an adequate workaround for you?

[kelemen]

I looked around the NB API if I could remove the last output line (so that I could print it after checking for links) but had no success even with dirty reflection hacks. So, the only possibilities I can imagine are the ones I have already listed.

[qcsoftware513]

One of the reasons I like the output window is the ability to get links. 99% of the time, I won’t have output that doesn’t have a new line at the end of it. This basically only happens when we are doing testing through the application with programmer input. In brief, our application would run without any user input in a production setting. In a test mode, we can trigger a series of inputs to test a specific scenario. It is these inputs that output data without a new line. So I think a configurable timeout would be fine for my use case.

I will see to implement it after #386 is settled in some form to make merging easier (it is quite annyoing to merge this branch after changes of these kinds into nb9 due to the large number of changes).

Thanks.
