Racket (formerly PLT Scheme) is a programming language suitable for implementation tasks ranging from scripting to application development, including GUIs, Web services, etc. It includes the DrRacket programming environment, a virtual machine with a just-in-time compiler, tools for creating stand-alone executables, the Racket Web server, extensive libraries, documentation for both beginners and experts, and more. It supports the creation of new programming languages through a rich, expressive syntax system. Example languages include Typed Racket, ACL2, FrTime, and Lazy Racket.
The ManEdit UNIX Manual Page Editor is an editor specifically tailored for UNIX manual pages. It has a preview viewer, uses the manual page XML format for easy editing, and comes with a tutorial and reference guide. It uses the GTK+ widget set and features syntax highlighting, a complete drag and drop system for easy viewing and editing, a crash recovery system, and sample manual page templates.
CodeWorker is a versatile parsing tool and a universal source code generator. It interprets a scripting language for producing reusable, tailor-made, evolving, and reliable IT systems with a high level of automation. The file formats to parse are described in an extended-BNF syntax. Template-based scripts drive the writing of patterns for generating code or text. The code generation knows how to preserve protected areas with hand-typed code and provides code expansion, source-to-source translation, and program transformation. It provides a native translation of CodeWorker's scripts in C++.
Opag, which stands for "Option Parser Generator", is a program to generate C or C++ code which parses command line options. It takes as input a description of the command line options you want your program to support. The output is a C or C++ function which finds these options in an array of strings (typically "argv", the second parameter of the "main" function) and sets variables accordingly. Short (single character) as well as long (GNU style) options are supported. It is also possbile to associate a help string with each option. Opag uses these to create a macro which expands to a string containing a nicely formatted description of the options.
Gimp User Filter is a work-alike to Adobe's Filter Factory. It is a generic image processing plug-in that can be used to create new filters for The GIMP without having to go through the process of learning about The GIMP's SDK. Many freely available filters that have been created for Filter Factory can also be used with this plug-in.
AutoCMS is a smaller CMS with the minimum needed to have a presence on the Internet. Its main file is less than 10kb large by default. No database is required. It only has the concept of one user (the admin). The password is protected with SHA1. CSS styles are easy to build and to change. Changing a page is very fast. XHTML and CSS code are validated by W3C validators. Data is stored in a PHP file which can be downloaded by FTP for backups. The generated contents are friendly for searchers. The result is visualized correctly in all browsers. It allows you to update all contents without having knowledge of programming.
nyu is a combination of modern academic approaches to parsing formal grammars from PEGs and expression grammars that represents the new state of the art in parser generators. nyu grammars are written in a powerful language based on PEGs (parsing expression grammars) but with modifications to allow both the AST and the parser to be specified intuitively in a single grammar. nyu outputs parsers that take advantage of the chilon::parser meta-programming library for C++. The generated parsers are almost as concise and readable as the input grammars, yet perform as well as hand-written C code. nyu ASTs are built using tuples, variant types, and lists, and allow self referential parsers and AST nodes to be manipulated. Advanced features such as hashed containers and grammar inheritance are also possible and well tested. nyu is currently powerful enough to deal with complex grammars and bootstraps its own parser.
