What’s the recommended tool/library to execute a major code rewrite of kotlin codebase which is not doable with simple find-replace

Say we use one library which has certain methods, annotations and there’s exist a new library with one-to-one mapping for each use case in old library.

Given there’s a fixed pattern on how code should be re-written using new library, is there a way to automate this process using code parser

My initial hunch is to use kotlin-embeddable or kotlin-poet but not sure if I’ll be able to maintain line numbers and keep rest of the codebase untouched

If automap is possible, do you even need mapping? Looks like duplicated model.

Intellij’s Structural Search and Replace might be an option. More powerful than a standard text or regex search, but doesn’t need to drop down to parsing and modifying AST

OpenRewrite doesn't have that many recipes for Kotlin though: https://docs.openrewrite.org/recipes/kotlin

yeah, it will be nice to start contributing some recipes especially when there are breaking changes
