I swear I saw somewhere an annotation/comment injection where I could tell IntelliJ some String is a path to an actual File and IntelliJ would show me a warning/error if the file did not exist. Does that ring a bell to anyone? I can't find it anymore. Did I just dream it?

@Language("file-reference")

I'm not sure why a file reference is a "language" 😄

[mbonnin]

Aaaahhhh thank you so much! 🙏

[mbonnin]

Is there a list of supported languages somewhere?

[Sam]

If you have the cursor over a String and use Alt+Enter for the context actions menu, you can choose "Inject language or reference" and you'll get a list. Immediately after choosing one, if you press Alt+Enter again, it'll add the relevant annotation.

[Sam]

I don't know of anywhere else the list of choices is documented, though

[mbonnin]

This is perfect 👌 Thanks again!

Is this annotation not available in AS? I can't seem to use it even when including the jetbrains annotation lib.

[mbonnin]

@Fergus Hewson it should be there (but it’s not KMP)

[Fergus Hewson]

Ah that is my problem 🙂 Thanks @mbonnin

[Adam S]

version 25.0.0 should support KMP 🤞

(Although I tried it and encountered problems in non-JVM targets)

When the annotation doesn't work, you can use a comment instead:

// language=file-reference
