Run the following the Java program multiple times, DEBUG CONSOLE sometimes add some newlines unnecessary.
PrintfTest.java:
import java.util.stream.IntStream;
public class PrintfTest {
public static void main(String[] args) {
IntStream.range(0, 10).forEach(it ->
System.out.format("This is iteration %d. Hello VS Code! Hello RedHat!%n", it));
}
}
DEBUG CONSOLE output:
This is iteration <- Unnecessary newline here.
0. Hello VS Code! Hello RedHat!
This is iteration 1. Hello VS Code! Hello RedHat!
This is iteration 2. Hello VS Code! Hello RedHat!
This is iteration 3. Hello VS Code! Hello RedHat!
This is iteration 4. Hello VS Code! Hello RedHat!
This is iteration 5. Hello VS Code! Hello RedHat!
This is iteration 6. Hello VS Code! Hello RedHat!
This is iteration 7. Hello VS Code! Hello RedHat!
This is iteration 8. Hello VS Code! Hello RedHat!
This is iteration 9. Hello VS Code! Hello RedHat!
Dump the DAP event:
{"event":"output","body":{"category":"stdout","output":"This is iteration ","type":"output"},"seq":12,"type":"event"}
{"event":"output","body":{"category":"stdout","output":"0. Hello VS Code! Hello RedHat!\r\nThis is iteration 1. Hello VS Code! Hello RedHat!\r\nThis is iteration 2. Hello VS Code! Hello RedHat!\r\nThis is iteration 3. Hello VS Code! Hello RedHat!\r\nThis is iteration 4. Hello VS Code! Hello RedHat!\r\nThis is iteration 5. Hello VS Code! Hello RedHat!\r\nThis is iteration 6. Hello VS Code! Hello RedHat!\r\nThis is iteration 7. Hello VS Code! Hello RedHat!\r\nThis is iteration 8. Hello VS Code! Hello RedHat!\r\nThis is iteration 9. Hello VS Code! Hello RedHat!\r\n","type":"output"},"seq":13,"type":"event"}
It looks like vscode debug console renders an extra newline for each outputEvent even if it doesn't end with CRLF.
