ascheja / rokkstar

A rockstar (https://github.com/RockstarLang/rockstar) parser/interpreter/transpiler written in Kotlin

Rokkstar

This is a WIP parser and interpreter for the rockstar programming language, written in Kotlin.

Project layout

• ast: abstract syntax tree classes
• typesystem: logic rockstar's dynamic types
• parser (uses ast): parser (and lexer) for building up an AST from source code
• interpreter (uses ast and typesystem): interpreter that traverses the AST

Using the runner via gradle

# starts the api on port 8080 (`Listen to ...` will always receive empty strings)
./gradlew run --args='api 8080'

# launches the interpreter on the given file (Will not work with `Listen to ...`, you have to run it manually in that case)
./gradlew run --args='run <file>'

Starting the api in a docker container

# start the api on port 8080
docker run --rm -p 8080:8080 ascheja/rokkstar api 8080

Plans for the future

• Add more tests, enable github-ci
• Add position tracking for tokens
• Improve error handling in Parser (try to recover from exceptions)
• Rockstar plugin for IntelliJ IDEA
• Provide a Docker image
• Make Rokkstar runnable on all Kotlin platforms (jvm, javascript, kotlin-native) and/or graal/substratevm
• Use llvm (via kotlin-native) to create a real compiler

Known Issues

• Poor error messages
