The code I have shown during Paris JUG session "In bed with ..." in september 2013

pattern-matching

Examples of pattern matching in Java

pattern-matching-runtime

A proof of concept of the runtime behaviour of the pattern matching in Java

pratt_parser

Implementation of a Pratt Parser in Java

pro

A Java build tool that works seamlessly with modules

pro-demo

A small demo of pro

proxy2

Better / faster proxy generator than java.lang.reflect.Proxy for Java (require 1.7)

proxy2-jfokus

Examples using proxy2 for JFokus VM Summit

record-util

Some utility classes around java records

reducedjs

A reduced set of the JavaScript feature that can run fast on the JVM

refactoring

smartass

A toy language used to explain how to implement a dynamic language on top of the JVM

snowcamp-demo

one JDK8 application used as demo to show how to migrate to JDK9

streams-utils

Streams Utils is a set of operations written on Java 8 Streams. It allows several basic operations that are not available in the the Java 8, and that have proven to be very useful in some cases. It is an updated version of More Spliterators.

struct-of-array

Two data structures with the API of an array of structs (AoS) and the internals of a struct of arrays (SoA)

switch-carrier

A study of the carrier factory for the destructuring switch

switch-pattern-combinator

A prototype showing how to generte the bytecode for a switch on patterns

tomahawk

A better Java API for Apache Arrow

umldoc

Automatically generates documentation with the UML diagrams using either plantUML or mermaidjs

unicorn

a simple yet interesting dynamic runtime on top of the JVM

valhalla-generic-simulator

A simple prototype of how unified/specialized generics may work in the future

valuetype-lworld

Tests of Java value type (lworld prototype)

varhandle2

A safe yet efficient implementation of atomic operations for the JVM.

vector-handle

A high level API to express vectorized operations in Java

virtual-bean

A simple API to compose bean behavior based on annotations

vmboiler

A small library on top of ASM that generates optimistically typed bytecodes for dynamically typed JVM based languages

webapp-java17

A example of a Spring project using Java 17

write_your_dynamic_language_runtime

How to write interpreters or dynamic compilers for dynamically typed languages on top of the JVM

write_your_own_java_framework
