Hey, curious, what is the situation with Kotlin MPP support?
I have noticed a tracking issue and afaik this processor is based on JVM only compiler extension, but do you plan to bring support to all platforms?
Overall, very solid first impression, thanks for sharing this!

There is some work needs to be done in compiler to provide extension point for compiler plugins in other platforms. API itself is MPP compatible. If you are interested in trying out MPP you need to install a customized compiler in your local with the new extension points added. We can provide guide on how to build a compiler locally and use it 🙂

Do you plan to merge it with mainstream?

[Jiaxiang]

We do plan to do so, but it will take a while for the change to be released given the release cycle. It's a good practice to stick to a stable release, so I would recommend to checkout out ksp branch on our repo, which is rebased to 1.4-M1 tag, and then make changes to add extension points.

Sure, thanks 🙂

One more question: do you release this version of compiler somewhere separately?

[Jiaxiang]

No, the changes for extension point are still WIP, will let you know when it's ready, not sure if we want to make the compiler artifact hosted in repos.

@Jiaxiang I’d be curious on trying to make it work in mpp, could you give some hints?

[Jiaxiang]

MPP needs at least creating some extension points in the analysis pass of other 2 platforms (Native and JS), and will also requires further efforts to add implementations for symbols from other platforms. Regarding the new extension points work, in JVM the extension point is called PartialAnalysisHandlerExtension, which is not available in other 2 platforms. It can involve changes to compiler itself therefore you might want to contact JB before doing so..
