Open Source Flex Software for BSD

Xschem is a schematic capture program, it allows to create a hierarchical representation of circuits with a top down approach . By focusing on interconnections, hierarchy and properties a complex system (IC) can be described in terms of simpler building blocks. A VHDL, Verilog or Spice netlist can be generated from the drawn schematic, allowing the simulation of the circuit. Key feature of the program is its drawing engine written in C and using directly the Xlib drawing primitives; this gives top speed performance, even on very big circuits. I have succesfully managed to simulate complete VLSI projects with this tool, both digital (Verilog / VHDL) and analog (Spice). Schematics can be printed in SVG, PNG, PDF, formats. XSCHEM runs on Linux or other Unix-likes with Xorg server and on Windows with the Cygwin layer and required tools installed. Can be found also on github: https://github.com/StefanSchippers/xschem

MGFp is open parser implementation for the Mascot Generic Format (MGF). It uses bison/flex to define a formal grammar and provides the necessary C++ adapter classes. The software is provided under a BSD license. Development on SF.net has ceased. You can find the project at http://kirchnerlab.github.com/libmgf/

CLuMPI (OpenCL under MPI) is an implementation of the OpenCL interface which uses MPI as a back end

Gimp User Filter is a plugin for The Gimp (http://www.gimp.org/), originally written by Jens Restemeier back in 1997. This project is about maintaining the plugin, keeping it compatible with current versions of Gimp, and eventually extending its features

A strong, yet minimalistic Math-oriented Programming Language (MML) providing an easy-to-use console and a command-line script interpreter, targetted towards fast calculations for extremely big numbers, and bundled with a number of math libraries.

Standard ML of Sønder Tranders.

A compiler library for a language integrating all that is needed for completely defining whole sound/music compilations. From very basic stuff as defining oscillators etc in all their parameters up to note events and more.

gURL is a free, Open Source (GPL) HTTP request generator tool.

This is a flex/bison based reentrant parser library for parsing named configuration files. Suitable for static or dynamic linking it reads the file, validates format/content and constructs a parse tree which is returned to the application.

lilpM32 is a MIPS-like processor designed in Logisim, assembler program and documentation for them. Complete assembler and fully functional instruction set with I/O and subroutines features allow to write full-blown complicated programs.

Generate calendars in SVG format.

talc is a terminal calculator designed with very large number support and a simple grammar. It is designed to be both scriptable and interactive.

Txt2C is an utility written in C and LEX in order to create functions in C that shows by sdtout a text passed as parameter.

Txt2Perl is an utility written in C and LEX in order to create subroutines in perl that shows by sdtout a text passed as parameter.
