A modern programming language that makes developers happier.

Can anyone explain how incremental compilation/analysis at the file level works in IntelliJ ? I.e. how you did to avoid recompiling the entire file when the user makes a small change to that file ?

I would have thought that it's the job of the build system (Gradle), (+ possibly the kotlin's gradle plugin (?!)), to decide what needs re-compilation and not IntelliJ's.

I'm pretty sure the IntelliJ plugin does some caching to provide completions faster. That's the kind of optimization I'm interested to learn about

IDEA’s magic is completely independent of compilation. IDEA builds a parse tree itself and fills its cache from that. The parse tree is also available to plugins (I think).
How exactly incremental updates and caching work is an implementation detail, I guess.

Those are the details I am asking for :slightly_smiling_face:
