Static code analysis for Delphi 12 & 13 and Lazarus / Free Pascal. RAD Studio IDE plugin (32/64-bit) + standalone GUI + CLI, one engine. 201 rules (Pascal AST + DFM/LFM forms): leaks, SQL injection, dead handlers, hardcoded secrets, Unicode & Trojan Source, Win64 pointer bugs. SARIF for CI/CD, SonarQube push.
Apache 2.4 module to allow Pascal program to be executed just like scripting language
A language server protocal client written in Pascal (Delphi).
A debugger for delphi in visual studio code, and also a MCP server to give claude/copilot/etc authonomous delphi debugging capabilities
Delphi 12-compatible Pascal compiler for Win64 and Linux x86-64. Your Delphi code builds on Linux unchanged — and often runs faster. FPC/Unleashed fork with Unicode RTL and bundled memory manager.
Delphi units for JSON and (HTML) XPath
A unified compiler-construction meta-language designed to define and build programming languages within a single .mor file. By describing tokens, grammar rules, semantic analysis, and code generation in one place, developers can produce native Win64 or Linux64 binaries via a built-in Zig/Clang pipeline.
Delphi server side web programming language. Create web application using with pascal codes. Enjoy it!
Delphi-native, MIT-licensed RAG + linter for Delphi/Pascal source code. Symbol-exact + fuzzy + tree-sitter lint. Pure Delphi at runtime.
Editor, Debugger and Run Time Library for DWScript
This Lazarus project provides a RAD IDE for Free Pascal in the browser (Chrome) or desktop.
Native x86-64 code generation, JIT execution, SIMD, disassembly, and runtime instrumentation for Delphi
An expression parser and a virtual machine. A formula is compiled to a flat byte array and evaluated by a linear pass over it, with no allocation on the path of an ordinary formula. On x86-64 an optional accelerator compiles that bytecode to machine code and hands anything it declines back to the interpreter, so an answer is never fast but wrong. Results are cached by shape: once 2 + 3 has been compiled, 5 + 7 reuses the same script and only writes the numbers into a copy. 163 functions to call and 249 names in the table, your own functions and variables bound by address, symbolic differentiation. The Lazarus parser packages require FCL and define NOFORMS and NOGRAPHICS, so they install without LCL. WebAssembly uses a separate console configuration. Two units ask for more at their defaults, Thread through Application.HandleException and BlobManager through TGraphic; drop the defines and add the LCL to the package if you want them.
Language Tools In the Online Package Manager
Pascal Framework is a foundational library for Free Pascal, Lazarus and Delphi applications.
Markup, a specialized authoring language for creating semantic HTML with one consistent syntax. It replaces manual HTML coding with a streamlined, Turing-complete system that supports variables, logic, and reusable components. Delivered as a compiled DLL, it includes JSON binding, semantic analysis, and customizable rendering
compiler compiler coco/r pascal version
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.
Oregon Software's very old software technology.
Utilities for AI-assisted Delphi code analysis and builds.
object pascal AST parser
Import Delphi units to DWScript units
Very simple parser for Twig-like templates written in FreePascal / Lazarus
Language Server Protocol (LSP) implementation for Pascal/Delphi
An MCP server that gives an AI coding agent (Claude Code, or any MCP client) a semantic index of a Delphi / Object Pascal project group, built by PasTree.
BDD (Behavior-Driven Development) Framework for Delphi for use with DUnitX
A WebAssembly virtual machine for the Asuro operating system, written in Standard Pascal & designed to run on bare metal.
The utility DCU32INT parses *.dcu file and converts it into a close to Pascal form.
A simple testing framework for scripts produced in the jvInterpreter.
A High-Performance Virtual Machine for Delphi
