Tiger

Tiger is a Delphi-hosted compiler infrastructure that lets you generate native x86-64 binaries for Windows and Linux — executables, shared libraries, static libraries, and object files — entirely from code. There is no source language to parse. Instead, you construct programs using a fluent Delphi API: define types, declare functions.

Ganymede

Ganymede is a high-performance, embeddable scripting engine designed to compile source code directly into native x64 machine code via Just-In-Time compilation. It eliminates the need for virtual machines or interpreters, providing a flat C-style API for seamless integration with C++ and Delphi applications.

LangVM

LangVM is a Turing-complete language workbench for rapidly building custom programming languages. Using `.lvm` scripts, developers define lexing, Pratt parsing, semantics, MIR, and code generation without recompiling. It can run standalone or embedded in Delphi, enabling fast iteration and native, cross-platform language development.
