Features

• JVM Application Development - Enables the creation of software targeting the Java Virtual Machine using concise syntax and hybrid typing.
• Programming Languages - Provides a high-level programming language targeting the JVM that supports both dynamic and static typing.
• Code Prototyping - Executes code snippets and automates tasks quickly without extensive application boilerplate or project structures.
• Class Extensions - Allows injecting new instance or static methods into existing types using external descriptor files and extension modules.
• Runtime Meta-Class Extensions - Injects new methods into existing classes at runtime by modifying underlying class definitions via meta-classes.
• Dynamic Method Dispatch - Resolves method calls at runtime using a call site mechanism to support flexible typing and late binding.
• Java Interoperability - Enables direct integration and interoperability with Java libraries and classes within the same virtual machine.
• Metaprogramming - Modifies program logic and class definitions at runtime or compile-time to automate patterns and extend object capabilities.
• Metaprogramming Frameworks - Implements a framework for modifying program behavior and class definitions at both compile-time and runtime.
• Domain Specific Languages - Provides tools for creating specialized mini-languages with concise syntax to describe business logic or configurations.
• DSL Implementation Toolkits - Offers a framework for implementing the lexing, parsing, and generation phases of domain-specific languages.
• Hybrid Typing Systems - Combines dynamic method resolution with optional static type checking within a single language runtime.
• Scripting Languages - Provides a flexible language for executing custom scripts and automating tasks without application boilerplate.
• JVM Bytecode Compilers - Translates high-level syntax into compatible Java bytecode for execution on the Java Virtual Machine.
• Scripting Runtimes - Evaluates code snippets without a full application structure by bypassing traditional boilerplate and compilation steps.
• Abstract Syntax Tree Transformations - Provides capabilities to rewrite and generate AST nodes during compilation to implement custom language features and reduce boilerplate.
• Runtime Metaprogramming - Enables modifying program behavior and structure at both compile-time and runtime to automate tasks.
• Custom Script Executions - Provides the ability to execute custom logic via scripts to bypass full application structures.
• Call-Site Caching - Implements call-site caching to optimize dynamic method calls by reusing resolution results for subsequent invocations.
• Functional Programming Patterns - Supports processing data and performing transformations using logic based on functional programming paradigms.
• Custom Type Checking Rules - Supports adding custom type checking rules via scripts to modify static analysis and catch coding errors.
• Static Type Checking - Performs compile-time type validation to bypass dynamic dispatch and increase execution performance.
