I'm attempting to update a value printed to the console in order to implement a simple REPL that supports predictive commands.
So after "->" is printed to the screen using
Console.print("->")
and the user enters "d" followed by the "tab" key then then the existing output "->" should be converted to "-> dir"
I read the input using :
val input = scala.io.StdIn.readLine()
I have yet to implement the listener to determine when the tab key is pressed. At this point I'm attempting to prove if command line output can be updated in place.

Once upon a time, I had taught myself how to output a series of characters wherever my mouse cursor had last clicked; i.e, I was using it to spam cheats in AOEii campaigns. It pressed enter, printed the characters in "to smithereens", and pressed enter again every 0.5 seconds.
I can't for the life of me get that working again. Any knowledge on how to move the text output away from the console? This time I'm trying to use it to spam CK3 cheats in the debug console. I have the code written for the actual output, but can't move it to the correct place.
How can I change the keyboard shortcut in eclipse from sysout + control space to sout + enter like in sublime.
How can I change the keyboard shortcut in eclipse from sysout +
control space to sout + enter like in sublime.
The short answer is you can't. But you can modify an existing template, or add a new template, to create a shortcut of sout that will generate
System.out.println();
To do that:
Select Window > Preferences > Java > Editor > Templates.
Scroll down the list of existing templates and select the one named sysout.
Click the Edit... button.
Change the Name field from sysout to sout, and click OK.
You will be invited to either replace sysout with sout, or add sout as a new template. Pick whichever option is appropriate.
That's all there is to it. In the editor you can now type sout and press Ctl + Space to generate
System.out.println();
However, there is no real need to do any of that because when you press Ctl + Space after typing sout the template sysout is offered as the first possible match:
So without making any changes to Eclipse you can type sout and press Ctl + Space, then Enter (to select the first entry in the dropdown list) to almost achieve what you want.
While editing in Eclipse it is not possible to have any action triggered simply by pressing the Enter key. That's because the Enter key already has a well defined function: to move to the next line, taking any text with it that is to the right of the cursor.
If you could generate System.out.println(); just by typing sout and pressing Enter you wouldn't be able to create a line containing only sout.
in my setup I need some user input. Of course these have to be checked. That works quite well with your "Input validation expression" option.
If the input is valid the Setup is going to the next step as excepted
If the input is not valid, you write that i should display an error message. Since there is no option for error messages on user input I have created one myself with JOptionPane. This also works well, but it jumps every time in the error message - No matter if "next" or "back" is clicked. can not even click cancel without jump into the error screen.
Is there a other way to display the error message? or how do I leave the screen appear only when click on next?
You cannot leave the text field if the input validation returns false.
Another option is to validate the value in the "Validation expression" script of the screen. You can access the value of the text field via its bound variable there:
String variableValue = context.getVariable("variableName");
For error messages, it is recommend to use
Util.showErrorMessage("error message");
How to read data which ends with the ellipses(...) in java and selenium.
I have tried with the option as gettext().split(",")[0]. Each time the data length gets differently some times data will display with "," or some time data will display "Name..." in this situation it is difficult to get to know where the comma "," ends. When hover the mouse on the text will get display the full data on the tooltip. Please help how to handle it.
I'm having a problem with JTextArea (not a problem though).
I want to create my own college program, one of the function is to write down and save a list of homework each day. It's text area having the main function here, which is to type everything my lecturer said. But text area will act like Windows original notepad, which is not keeping the indentation. So my questions are:
How do I have a function where I press the SHIFT+TAB key it will decrease indentation by one.
If number 1 is possible, then how do my program have behaviour when I press ENTER key, it will have a new line with previous indentation? Just like NetBeans and other IDE.
Edited: I'm a beginner in Java, in truth, I'm making this program while studying Java in my college.
How do I have a function where I press the SHIFT+TAB key it will decrease indentation by one.
You need to use key bindings to listen for the user typing Shift+Tab.
If number 1 is possible, then how do my program have behavior when I press ENTER key, it will have a new line with previous indentation? Just like NetBeans and other IDE.
Use a similar piece of logic to capture the Enter key presses. Then, check the previous line in the editor and count the number of tab characters preceding the text. Output a similar number at the start of the new line.
you could use Javascript/jquery for indenting by inserting empty space of specific line. while pressing your hot key combination call function to insert five spaces on your cursor.
