Hello everyone, I have a very specific question which I believe I have an answer for myself but would like to know if others have a better idea ^^

I'm attempting to print the logcat output within an app and have used the -v color option but this uses ANSI codes such as [32m and Jetpack Compose Text() functions will print them literally.

Does anyone know if there is a way to interpret the codes and display the colours for the string? My naive approach would be to manually parse the codes but I honestly would prefer not to 😅

Compose text does not support ANSI control characters out of the box if that’s what you’re asking - that would be a pretty ridiculous feature for a UI toolkit to support I think.

Would be neat to publish a library that parsed them to AnnotatedStrings or something though

[Maxime Michel]

Yeah that's what I assumed ^^ Very niche need but a library would be cool!

Bonus points if you support bell 😛

proper VT100/ANSI sequence parsing is hard

[ephemient]

you could get the messages directly from the system instead of trying to parse a command's output:
src/androidNativeMain/cinterop/logging.def
src/androidNativeMain/kotlin/Logcat.kt
src/androidMain/kotlin/Logcat.kt
src/androidInstrumentedTest/kotlin/LogcatTest.kt
(tbf there's still a bit of parsing involved, but it can't get confused by embedded newlines or other funny sequences inside messages)

oh nevermind I forgot that READ_LOGS was restricted to system only on real devices…
