Is there any way that i can change the color of the text output in the console in the program?
已回答
So in school we had to write a program that can detect discriminative sentences and my plan was the I wanted to print out all of the text at the end of the program but then change the color of the sentences that my program flagged as discriminative in red for example so they stick out. If there is any way I can do that would be really cool. Thx for the help

ANSI colors are supported in the console output: https://youtrack.jetbrains.com/issue/IDEA-69880 .
See https://stackoverflow.com/a/5762502/104891 .
Thank you so much !
This works only in Java console, when I run the program. In debugger console I see no colors.
Is there a way to do it in debugger?
Using on Ubuntu 20.04:
IntelliJ IDEA 2024.3.4.1 (Community Edition)
Build #IC-243.25659.59, built on March 4, 2025
Debug mode should behave exactly the same as it's using the same console tool window component as Run:
What run/debug configuration type do you use? Can you share a sample project and a screenshot of the issue? Use https://uploads.jetbrains.com for private uploads and share the ID here.
I did not express myself correctly. What I mean is that debugger does not show colors in Frames/Variables window:
Thanks for clarifying. This was never requested for the debugger variables view. The goal of this view is to display raw values of the variables, and interpreting the colors may be not what the user would expect.
I think such an option would be very useful. In fact, its absence makes debugging very inconvenient.
You can try creating a custom type renderer that will strip all ANSI codes from messages for easier debugging.
See https://www.jetbrains.com/help/idea/customizing-views.html#renderers and https://kamilszymanski.github.io/custom-type-renderers-in-intellij-idea-debugger/ .
Thanks, but unfortunately the documentation is incorrect and lacks clearness.
First, recommendation to “Right-click anywhere in the Variables tab and select Customize Data Views” does not work. In debugger this click does nothing, and when debugger is is not running, this option is grayed out.
Fortunately I found how to do it via Settings→Build, Executions, Deployment→Debugger→etc.
But I cannot figure out how to create a renderer that I need. In my case I want to to do something like:
replaceAll("\u001B\\[.*?m", "")How can I do it?
I sort of figured it out. This syntax is for java.lang.String:
this.replaceAll("\u001B\\[.*?m", "")
The problem is that it works only for objects of String. If I define myObj.toString(), the renderer will work for this expression, but debugger will still show mObj with ansi codes. So it looks like I have to create the same renderer for my every class, correct?
A little better:
a renderer for java.lang.Object and added to 'Use list of expressions"
this.toString().replaceAll("\u001B\\[.*?m", "")
then in debugger I still see the raw string for myObj, but underneath it I can see the text stripped of ansi codes but NO COLORS!
Anyway, it does not do what I'd like to see.
Hi Alexander Bootman
Thanks for taking the time to test the way to achieve colors in the “ Frames & Variables” debugger window. I'm sorry that you were not able to find a way to set them.
As Serge Baranov mentioned, the debugger was not intended to be used with configurable colors, just to show raw data. However if you can send an example of what your object is and how you are trying to implement it, I can check if some other workaround could be done or even check if a feature could be requested. Also please let me know which IntelliJ IDEA version are you running.
For me this is what I can see with default rendering. Different colors are shown for values.
