madDisAsm

. The package features a full x86 disassembler including MMX, 3dNow enhanced, SSE and SSE2 support. The disassembler can examine a single x86 instruction see ParseCode or a full function see ParseFunction and either return a short analysis or a full text disassembly. Register contents are watched/followed if possible, this improves the analyses for jump/call targets. Case/switch jump tables are automatically detected and handled correctly.

Simplified pascal compiler for Linux

A compiler for a simplified pascal language. It runs in a x86 computer with a Linux-based OS. The purpose of this project is to show how a source code in pascal can be converted to x86 assembly.

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.

Myrissa

Myrissa is a modern systems programming language by Jarrod Davis, combining Pascal readability with robust C ABI interoperability. Written entirely in Delphi, its self-contained compiler generates native x86_64 code for Windows and Linux, with built-in linking, managed strings, unit testing, exception handling, and low-level control.

MathParser

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.

Projet_fin_module_compilateurs

MSEide+MSEgui

MSEide is a Rapid Application Development IDE for platform independent rich GUI applications in the Pascal language. It comes with its own GUI toolkit called MSEgui, which ensures programs are portable. MSEgui has identical look and feel on all supported platforms, the look of the widgets is highly configurable. The widgetset library is completely written in Pascal and links directly to xlib on Linux and FreeBSD and to gdi32 on win32/64. MSEgui includes sophisticated DB-access components and DB-aware widgets. Main goal of development is to provide a handy, stable and very productive tool for professionals. MSEide+MSEgui currently runs on i386-linux, i386-win32, x84_64-win64, x84_64-linux, x86_64-freebsd and arm-linux. Main git repository: https://gitlab.com/mseide-msegui/mseide-msegui

Oberon V4

Here you can find both an Oberon V4 system for Linux (x86) and a collection of Oberon V4 sources for various other platforms. Oberon V4 was implemented at ETH Zurich for several platforms. Binaries can be found on their server[1] and on the one of the University of Linz[2] where Mössenböck's group did further development after he left ETH and the Group at ETH concentrated on System 3. More Information can be found in the wiki https://sourceforge.net/p/oberon/wiki/Home/ of this Project and on Wikipedia https://en.wikipedia.org/wiki/Oberon_(operating_system). In 2013 they were moved here for easy access and, in case of interest, collaboration on further development. The Oberon mailing list[3] is an established channel for its discussion and followed also by the administrators of this SF project.

Task-Runner

This program serves for Software build automation, executing sequential tasks, including database backup/restore, running SQL scripts, Windows shell commands, Pascal scripts, passing variables through the whole task execution chain, and many more. You can set up a list of global parameters, such as Delphi application path, and use these parameters in tasks. You can even call a separated task chain from another task in the same way as you call Delphi procedure or a function, with passing parameters.
