Hi, I tried ./ktlint -F app/src/**/*.kt from my Android project root directory. All works and it corrected the file format. However it is not following AndroidStudio default rule. So I tried ./ktlint --android applyToIDEA -F app/src/**/*.kt, but it crashes as below.

Exception in thread "main" picocli.CommandLine$UnmatchedArgumentException: Unknown options: -F, app/src/androidTest/java/com/example/pdfreader/ExampleInstrumentedTest.kt, app/src/main/java/com/example/pdfreader/FileDownloader.kt, app/src/main/java/com/example/pdfreader/MainActivity.kt, app/src/main/java/com/example/pdfreader/PageAdaptor.kt, app/src/main/java/com/example/pdfreader/PageHolder.kt, app/src/main/java/com/example/pdfreader/PdfReader.kt, app/src/test/java/com/example/pdfreader/ExampleUnitTest.kt

What did I do wrong? I tried remove the -F, it is not working as well? I think I might have miss something…. any help? 🙏

Reading the docs (https://github.com/pinterest/ktlint#usage) it looks like you should be trying:
./ktlint -F "app/src/**/*.kt"
Note the quotation marks - I guess without them your shell is expanding the glob expression before calling ktlint?

applyToIDEA is actually a cli subcommand that applies ktlint’s code style to your .idea/codeStyles so has nothing to do with formatting

[romtsn]

so you have to just run ktlint applyToIDEA separately and then run your format command

[romtsn]

but I have to warn you that the integration with idea is not perfect and it’s missing some rules, therefore you will still have misalignments with AS default formatting

Thanks @romtsn. Just got to learn that applyToIDEA is actually adding KtLint code style to Android Studio. Is there the other way round? i.e applying Android Studio default/project rule to Ktlint?

--android cli swith uses Android flavor of code style

there is work in progress to move IDE integration via .editorconfig file
