Kotlin Utils

The Kotlin Utils provide certain meta-level functionality for this project, such as printing the AST of a kts file.

Printing ASTs to Dot

You can print the AST generated from a *.kt or *.kts file in TXT or DOT (Graphviz) format, either on stdout or to a file. To print the AST to stdout:

  1. Run ./gradlew utils-kotlin:printAst --args="<txt|dot> <path-to-input-kotlin-file>"

To print the AST into an output file, simply add the path of the output file as second command line argument:

  1. Run ./gradlew utils-kotlin:printAst --args="<txt|dot> <path-to-input-kotlin-file> <path-to-output-file>"

So for instance, if you want to visualize the AST for the file Example.kt do the following (you'll need to install graphviz for this):

./gradlew utils-kotlin:printAst --args="dot Example.kt /tmp/ast.dot"
dot -Tpng /tmp/ast.dot -o /tmp/ast.png

Now open the file /tmp/ast.png with an image viewer of your choice. See the documentation of the dot tool to find various alternative output formats.
