A parsing toolkit that supports both top-down (LL(1) and Simple Precedence) and bottom-up parsing (LR(0), SLR(1), LR(1) and LALR(1)). The toolkit also supports generating Java parsers for all the bottom-up parsing methods, based on a CUP definition (similar to Yacc and CUP, but not restricted to LALR parsers only).
yagg, given YACC-like and LEX-like input files, generates a C++ program that generates all strings of a user-specified length. This program can then be used to generate inputs for testing, or to validate that a grammar accepts the strings that you think it does. The grammar file provides the grammar productions for string generation, along with optional action blocks that can perform context-sensitive checks in order to limit the generated strings. The LEX-like terminal generator file provides specifications that instruct the program how to generate strings for terminals in the grammar.
Hormiga is a language designed to be simple and powerful, allowing users without software programming knowledge to make the programs needed to automate the calculations of everyday problems. Generally, it is necessary only for the users to be aware of the problem they want to solve. The language allows programmers to focus on the problem and not to worry about the interactive interface with the user. The programmer will have to state the instructions to solve a problem, in the same way they would do manually. The steps may depend one upon the other. Like most languages, Hormiga has support for functions and the possibility of creating libraries of commonly used code. Unlike most languages, Hormiga automatically and dynamically creates the graphical user interface (GUI) for programs, has support for calculating definite integrals in multiple dimensions, and incorporates a new concept called Step, similar to a procedure of Pascal, but allowing you to state dependences between them.
Signal Applications To Audio Networks is a program aimed at different signal processing tasks. The primary type of signals are audio signals. The user describes networks of different modules using a special language, and the modules are dynamically loaded libraries. The system can be used to create music from scratch, or to process already created audio files, and depending on the complexity of the network versus the capacity of the host machine, everything can be done in "real time".
links2world Firewall is an iptables script generator for Linux 2.4.x or newer kernels. The configuration file is very human readable and easy to understand and write. It does not matter if you have one, two, three, or twenty network interfaces; it is able to generate stateful iptables rule sets that control the packet flows between all the networks your machine is attached to.
OpenSMTPD is an RFC compliant, secure, and simple SMTP server ported from OpenBSD to Linux. It supports the SMTP protocol, including SSL versions for added security, virtual domains, forward files, and external delivery agents like procmail, and can do most of the basic things that other MTA implementations do.
