Display error messages from Compiler and Linker in red...

[trlafleur]

Describe the problem

In the Arduino IDE 1.x output panel, content received from the standard error stream (AKA "stderr") is colored differently (with the default theme, in red) than output received from the standard output stream ("stdout"). This makes the output easier to read, and highlights the content which may indicate a problem.

Arduino IDE 2.x displays all output in the same color, which makes it more difficult to read, and easier for the user to miss important content.

This for example is how it looks like in the 1.8.9 IDE (left) and the 2.0.0 IDE (right) with both the same errors

This is a great idea. We used to have this feature but it was not working correctly so I removed it. Now, I quickly added it back to my local env as it was a couple of lines of code. It's not what you would expect 😊 This is how it looks like:

Unfortunately, the CLI (that powers the new IDE) doesn't use the streams correctly. (See the CLI API here). Only the the Compilation error: Error: 2 UNKNOWN: exit status 1 part goes to the error stream, so the IDE cannot do much and leaves the rest white. We need some help from the CLI team with this issue.

would be great if that will be turned on in B4 or B5 again.. Running b4 now and really searching for the errors as everything is white.
Also would be great if you could click on the error and the IDE would focus / highlite on that error.

I think the basic problematic is not solved yet (Beta 7):

Errors are still not "highlighted" or obviously visible - or is any configuration needed for this?

Correct, as should be clear from the fact that this issue is still open. We close issues once they are resolved.

@alve89 for support requests, please use the dedicated category for Arduino IDE 2.x on the Arduino Forum:
https://forum.arduino.cc/c/software/arduino-ide-2-0-beta/93
I'll be glad to help you out over there.

My bad, I misinterpreted the "closed" icon! I thought it is for this issue but it is for #353, so my post can be ignored. Thank you for your link anyway!

There is a dedicated issue tracking this request here: #118
