TerminalDetection not detecting IntelliJ

[bkahlert]

The TerminalDetection computes AnsiLevel.NONE although I'm running my unit tests inside of IntelliJ (Build #IU-221.6008.13, built on July 19, 2022).

The runningInIdeaJavaAgent method does not match. On my mac ManagementFactory.getRuntimeMXBean() returns the following elements

0 = "-Dorg.gradle.internal.worker.tmpdir=/Users/bkahlert/Development/com.bkahlert/kommons/build/tmp/jvmTest/work"
1 = "-Dorg.gradle.native=false"
2 = "-agentlib:jdwp=transport=dt_socket,server=n,suspend=y,address=127.0.0.1:56426"
3 = "-javaagent:/Users/bkahlert/.gradle/caches/modules-2/files-2.1/org.jetbrains.kotlinx/kotlinx-coroutines-core-jvm/1.6.1/97fd74ccf54a863d221956ffcd21835e168e2aaa/kotlinx-coroutines-core-jvm-1.6.1.jar"
4 = "--add-opens=java.base/java.util=ALL-UNNAMED"
5 = "--add-opens=java.base/java.lang=ALL-UNNAMED"
6 = "-Xms128m"
7 = "-Xmx512m"
8 = "-Dfile.encoding=UTF-8"
9 = "-Duser.country=US"
10 = "-Duser.language=en"
11 = "-Duser.variant"
12 = "-ea"

System.getProperty("sun.java.command") reports "worker.org.gradle.process.internal.worker.GradleWorkerMain 'Gradle Test Executor 61'"

My environment reported by System.getenv() does neither contain IDEA_INITIAL_DIRECTORY, __INTELLIJ_COMMAND_HISTFILE__ nor TERMINAL_EMULATOR.

The following environment properties might help you:

...
"JAVA_MAIN_CLASS_56145" -> "worker.org.gradle.process.internal.worker.GradleWorkerMain"
"TOOLBOX_VERSION" -> "1.25.12424"
"__CFBundleIdentifier" -> "com.jetbrains.intellij"
"SHELL" -> "/bin/zsh"
"__CF_USER_TEXT_ENCODING" -> "0x40E34E6:0x0:0x0"

Until IntelliJ is consistent about setting an environment variable, it's probably not possible to detect it in all cases. If you know of any envvar etc. that we can use, I'm happy to add it.

Does that __CFBundleIdentifier value change if you invoke your program from gradle on the command line, or via java -jar?

For the record, in IntelliJ IDEA 2023.2 I'm getting colored output with Mordant in the Run tab. However, the terminal's width does not seem to be detected correctly (TerminalInfo says it's 79), as my grid is truncated.

[ajalt]

I suspect it's not possible to detect terminal size in IntelliJ's run console. On Windows at least, GetConsoleScreenBufferInfo fails. Even powershell itself can't detect anything.

I have a problem when I try to create a fat jar, no problem with IntellI console when I use a run. But when a create a fat jar, I use a java -jar, mordant crashes

It is a problem with JNA, you need to include it to execute as a jar https://mvnrepository.com/artifact/net.java.dev.jna/jna/5.13.0

No problem with 2.0.0-beta9

Maybe the whole issue will get resolved with https://blog.jetbrains.com/idea/2024/02/the-new-terminal-beta-is-now-in-jetbrains-ides/?

[robstoll]

on Unix like Systems it could work to see if the _ env variable contains idea, most likely also not that reliable but better than nothing IMO.
