ProgressBar deletes previous text in IntelliJ Terminal (Jedi)

[zinoviy23]

Version: mordant-jvm:2.0.0-beta8 OS: MacOS 13.0.1

I've noticed, that my application with progress bar works fine in iTerm, but works strangely in IntelliJ Terminal (I've checked on IntelliJ IDEA 2022.3 RC). Even it works fine in IntelliJ Terminal but inside docker container with -tty.

I think the problem is in the detection of ij terminal:

val ij = isIntellijConsole() // intellij console is interactive, even through System.console == null

However, for me, ij terminal has System.console != null.

So, when I unset env variables from com.github.ajalt.mordant.terminal.TerminalDetection#hasIdeaEnvvar my program starts working as expected.

I've created small reproduce project: https://github.com/zinoviy23/terminal-kotlin-test There is a small script run.sh. When it executed in ij terminal like ./run.sh, progress bar deletes previous lines. But without ij terminal environment variables it works fine: ./run.sh -e.

I tested in both 2022.3 RC and in 2022.2.4, and the progress bar worked correctly in both cases. System.console == null in both versions for me. Is it possible you are using a different terminal somehow?

I don't know😕 I am using zsh with oh-my-zsh. I've added env printing to my example, for me it prints:

I've recorded how it looks for me: Working example (without env variables): And execution in ij with IJ Terminal variables.

Thanks for the info and recordings, that's helpful.

Can you repeat the test but by running a task from the ide rather than the terminal? (i.e. click the ▶ gutter icon next to fun main in your example repo) I'm curious if the behavior and environment variables are the same in both cases.

Running Kotlin main produces the next environment output in the Run Toolwindow

And it also works fine. (As I understand it detects idea runner from here com.github.ajalt.mordant.internal.MppImplKt#runningInIdeaJavaAgent)
