Per Brinch Hansen's SuperPascal compiler and interpreter, ported to Free Pascal for modern 64-bit Linux, with examples and automated tests.
Delphi-native, MIT-licensed RAG + linter for Delphi/Pascal source code. Symbol-exact + fuzzy + tree-sitter lint. Pure Delphi at runtime.
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.
An R5RS Scheme in JavaScript.
This Zig-based LLVM analysis framework focuses on static unsafe/ffi boundary analysis.
Coco/R is a compiler generator, which takes an attributed grammar of a source language and generates a scanner and a parser for this language. The scanner works as a deterministic finite automaton. The parser uses recursive descent. LL(1) conflicts can be resolved by a multi-symbol lookahead or by semantic checks. Thus the class of accepted grammars is LL(k) for an arbitrary k.
This Lazarus project provides a RAD IDE for Free Pascal in the browser (Chrome) or desktop.
PaskalCPP is a systems language by Jarrod Davis: Pascal/Oberon-style syntax that transpiles to C++23 and builds with a bundled Zig/Clang toolchain. Mix PaskalCPP and C++ in one file, no bindings. Includes a Delphi-built compiler and language server, an Electron/Monaco editor, and diagnostics mapped to your source. Native Windows and Linux binaries.
Pascal Framework is a foundational library for Free Pascal, Lazarus and Delphi applications.
Delphi Uses Analyzer - analyze unit dependencies, cycles etc.
An open source implementation of a language server for DWScript
Lua 5.1, natively ported to Delphi and FreePascal, implementing the Lua 5.1 C ABI as a drop-in replacement for lua5.1.dll / .so / .dylib
OptiPerl is a fully integrated developing environment for creating, testing, debugging and running perl scripts
Smoketest re-imagined. A lightweight, dependency-free unit testing framework for Delphi, with pluggable result formatting (xUnit 2 OOB)
Updated version of https://sourceforge.net/p/lazarus-ccr/svn/HEAD/tree/applications/gobject-introspection

Delphi Install Helper is a command-line tool for automated installation, uninstallation, and building of Delphi component packages.
compiler compiler coco/r pascal version
RTTI-based automatic language translator engine.
Myra is a minimal systems programming language inspired by Oberon and Pascal that compiles into C++23 using the Zig toolchain. Its core philosophy emphasizes a clean, unambiguous syntax while providing seamless interop, allowing developers to intermix raw C++ code directly within Myra source files. Pascal. Refined.
Command line utilities to modify Free Pascal and Lazarus .po translation files
A user-friendly JSON library for Free Pascal with automatic memory management.
A small command line utility which allows you to generate Delphi package files (DPK) based on the given template file.
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.
