Is someone familiar with ASM Transformations?

[Daniel Rampelt]

I'm just getting started with them but I made a basic JVM compiler plugin with ASM transformations

[Imran/Malic]

can you send me the repo

Or better, did you work with the Remapper

[Daniel Rampelt]

didn't use remapper at all, I used the TransformationMethodVisitor

[Daniel Rampelt]

my use case was just for changing the body of a method so that gives you a MethodNode for which you can modify the list of instructions

[Imran/Malic]

Can you send in the file where you do that

Using the TreeApi kills compilation time. Why didnt you use an MethodeVisitor?

[Daniel Rampelt]

I was having trouble getting the information I needed with just MethodVisitor, so for the first version I just wanted to get it working. Going to look into using MethodVisitor again to make it faster later

Thanks for sharing @Daniel Rampelt 👍🏽

[Daniel Rampelt]

No problem 🙂

[Imran/Malic]

Yes for sure. I am going to share it here if I find valuable ressources.

[Daniel Rampelt]

Thanks, I'll be looking forward to it 👍
