kotlinlang

Hi, the IntelliJ button - convert to Kotlin works great, but leaves some things I'd love to automatize.

Do You know a tool that uses AST, and can convert following code?
`"Hello, %s".formatted(name)` -> `"Hello, %s".format(name)`

I'm not looking for regexs, I tried Kotlin complier API - with some chatgpt promps, but I keep having troubles converting even such simple code - I can parse it, find the relevent method, but not replace it :confused:

Basically I'm looking for something like <https://errorprone.info/docs/refaster> - a tool that allows automated refactorings OR a piece of code where is the Kotlin compiler setup correctly :slightly_smiling_face:

My trouble isn't just `formatted` - I have 500K LOC project, and I want to resolve all problems at once

Have you tried structural search and replace in intellij?

I'd like to use something that can be automated - I'm planning doing tens of such refactorings

But I found solution today - <https://github.com/pinterest/ktlint/tree/master> - it uses PSI under the hood, but have interface that is easy to run :white_check_mark:

There is also OpenRewrite, a general tool for batch automation of refactoring.
