GraalVM: metaprogramming inside a polyglot system (invited talk)

Abstract

GraalVM is a polyglot virtual machine for running applications written in a variety of languages such as JavaScript, Ruby, Python, R, JVM-based languages like Java, Scala, Kotlin, and LLVM-based languages such as C and C++. GraalVM enables interoperability between different programming languages in a shared runtime, and can run either standalone or embedded in other software systems such as Node.js, the Oracle RDBMS, and MySQL. In this talk I will give an overview of GraalVM and present how polyglot features such as language interoperability and language-agnostic instrumentation are enabled in GraalVM by means of VM-internal metaprogramming.
