Introduction to the Eclipse scripting tool Groovy Monkey. Groovy Monkey allows for you to engage in API exploration, Task Automation, Plugin prototyping and collaboration in a lightweight and simple way.
Software development has shifted focus from efficiency to productivity, reusability, and user-friendliness. Object-oriented programming (OOP) models objects that contain data and methods. Key OOP concepts include inheritance, where subclasses extend and modify superclass features. An integrated development environment (IDE) combines tools like editors, compilers, linkers, and debuggers. Java uses a hybrid approach of compiling to bytecode, then interpreting for platform independence. Console applications use text input/output. Graphical user interface (GUI) applications use menus and buttons. Applets run in web browsers.
Build Great Networked APIs with Swift, OpenAPI, and gRPCTim Burks
This document discusses building APIs with Swift, OpenAPI, and gRPC. It introduces protocol buffers for defining data structures, and gRPC for building APIs. It recommends using the gnostic tool to convert OpenAPI descriptions to protocol buffers for use with gRPC plugins. This allows building high-quality code generators in different languages by separating the generator from the API description parsing. The document provides examples of building gRPC APIs and clients in Swift.
Java is an object-oriented programming language that was initially developed by James Gosling at Sun Microsystems in 1991.

Hand Rolled Applicative User ValidationCode KataPhilip Schwarz
Could you use a simple piece of Scala validation code (granted, a very simplistic one too!) that you can rewrite, now and again, to refresh your basic understanding of Applicative operators <*>, <*, *>?
The goal is not to write perfect code showcasing validation, but rather, to provide a small, rough-and ready exercise to reinforce your muscle-memory.
Despite its grandiose-sounding title, this deck consists of just three slides showing the Scala 3 code to be rewritten whenever the details of the operators begin to fade away.
The code is my rough and ready translation of a Haskell user-validation program found in a book called Finding Success (and Failure) in Haskell - Fall in love with applicative functors.

UI5con 2024 - Bring Your Own Design SystemPeter Muessig
How do you combine the OpenUI5/SAPUI5 programming model with a design system that makes its controls available as Web Components? Since OpenUI5/SAPUI5 1.120, the framework supports the integration of any Web Components. This makes it possible, for example, to natively embed own Web Components of your design system which are created with Stencil. The integration embeds the Web Components in a way that they can be used naturally in XMLViews, like with standard UI5 controls, and can be bound with data binding. Learn how you can also make use of the Web Components base class in OpenUI5/SAPUI5 to also integrate your Web Components and get inspired by the solution to generate a custom UI5 library providing the Web Components control wrappers for the native ones.

Integrated with the Java compiler.
Based on annotations. The developer's annotation processor
receives most of the program's AST.
7. USED FOR ?
RPC stubs,
Reflection stubs,
UI generation,
Configuration file generation,
Code checkers, Build breakers,
Dependency injection,
Glue code generation,
Your own needs !
8. IN THE GWT CONTEXT
GWT 3 will abandon generators because the functionality
exists in standard Java : JSR 269.
Even with GWT 2.8 it makes sense to use it.
Causes migration problems, with most of the time quick
resolution.
9. GOOD POINTS
API is easy to use.
Generated code is visible and debuggable,
Generated code is known before compilation so you can
reference it directly (no GWT.create).
No overhead at runtime.
Does not depend on byte code : GWT compatible
10. BAD POINTS
Only annotated elements trigger processing. API makes it
difficult to coordinate processing of multiple classes over
multiple rounds (bad for incremental compilation).
Dependency to external resource is not managed either.
13. APT
Introduced in JDK 5, was
removed with Java 7 because it support new language
elements.
Annotation Processing Tool

API includes packages.
14. PLUGGABLE ANNOTATION PROCESSING API

has been included since Java 6 (2006).JSR-269
Runs inside of .
API is able to welcome new language features.
15. HOW IT WORKS
Annotation processors must be registered.
Java source files are compiled during rounds.
Each round, processors are activated and receive the
program's AST.
They can then generate files which will be part of the next
round.
When no file is generated during a round, real compilation
happens.
22. REGISTERING THROUGH SPI
Java compiler searches annotation processors through SPI.
Add a file named META-
INF/services/javax.annotation.processing.Processor containing
the annotation processors' fqn list :
Other ways to register : has special flags. The
also has methods to set the processors to be
used.
23. PACKAGING
The simplest way is to have the annotation and its processor
in the same package.
Maven tip: dont forget to use the<compilerArgument>-
proc:none</compilerArgument> options
24. USING THE PROCESSOR
In a project with the processor's jar in the classpath, we can
use the annotation...
Eclipse tips :
Eclipse uses its own java compiler, JDT. Use m2e-apt to
configure your project if you work with maven.
Don't forget to close the processor project to have it activated.
28. HOW IS IT POSSIBLE ?
Using the not yet generated file is possible because the java
compiler deffers processing of the
NotFoundSymbolException.
The error is raised at the end of the parsing and annotation
processing process if the symbol has not been generated.
30. API OVERVIEW
Filer class : generate files (source, byte-code, resource)
Language Model classes : browse the program's structure,
Messager class : to communicate with the user,
Other tools : element and type tools
see javadoc of the javax.annotation.processing and
javax.lang.model packages.
31. API : JAVA SOURCE REPRESENTATION
Element : representation of a language construct (class
declarations, methods, ...). Ex: , ...
Supports all the language structures through the
and methods.
Hierarchical structure : ,
.
TypeMirror : Type representation, almost like Class<?>
32. API : ACCESSING ELEMENTS
Elements are given as parameters in the
method of the generator. Annotated elements are retrieved
like this :
.
All the classes parsed during the current round can be
obtained with :
.
Elements can also be retrieved with the utility methods :
,
and .
34. API : MESSAGER
Outputs messages to the user.
Can also generate errors and break the build. Very handy to
assert things on the code.
IDE integration : hints on the API for the user.
35. API : TOOLS
Many tools can be retrieved from the
field of the
Other static methods and classes are helpful :
42. LIMITATIONS
Not a full access to the code's AST (instructions).
Processors cannot depend one on the other.
Incremental compilation is difficult when having
dependencies to more than one element or to external files.
on Eclipse : , on maven : have to disable incremental
compilation.
Most of the time those limitations are not embarassing.
43. HACKING
: based on JSR 269 and hacking both javac and jdt
in order to acces to internal implementations and mutate
the class AST.

44. NOTE ON USING TEMPLATES
Try to generate the minimal amount of code, and base it on
generic implementations. This will ease debugging.
