A [Squeak/Smalltalk][squeak] VM and Polyglot Programming Environment for the [GraalVM][graalvm].

Getting Started

Download and extract the latest [TruffleSqueak standalone][ts_latest] for your platform.

Run the following in a terminal to start TruffleSqueak:

bin/trufflesqueak [<option>...] [<imageName> [<argument>...]]

(Optional) Install additional languages (only available in a JVM standalone):

# Evaluate the following from within TruffleSqueak
Polyglot installLanguage

# or run the following on the command line
bin/trufflesqueak-polyglot-get js # or ruby, python, java, llvm, wasm
