Test task for the "Natural Language Code View" internship.

The CLI tool takes the only argument: the path to a Kotlin file. You can try running the tool against Example.kt by simply clicking "Run" in IntelliJ.

Code is parsed with kotlin-grammar-tools. I extended the parse tree class with several extra methods for searching in trees.

Unit tests are implemented.

kotlin-grammar-tools doesn't keep the source code parts in parse results. I had to concatenate the tokens of a function to restore its source code. This method doesn't preserve formatting; however, it would be enough to process the code with LLM.

If the original formatting was important, the solution would be to rewrite the Parser library from kotlin-grammar-tools for storing original code in trees.
