Ding is a dictionary lookup program for the X Window system on Linux/Unix. It comes with a German-English Dictionary with about 253,000 entries. It is based on Tk version >= 8.3 and uses the agrep or egrep tools for searching. In addition ding can also search in English dictionaries using dict(1) and check spelling using ispell(1). It has many configuration options, such as search preferences, interface language (English or German), and colors. It has history and help functions and comes with useful key and mouse bindings for quick and easy lookups.
Ctalk adds classes, methods, operator overloading, inheritance, and complex object expressions to otherwise standard C programs. Programs can use only a few Ctalk objects and methods in an otherwise standard C program, but the language can be used to write entire programs also. Ctalk works on most if not all of the systems that support GCC, the GNU C compiler. The package includes the language, class and run-time libraries, example programs, tutorial, and language reference.
The DUP System is a language for productive, parallel, and distributed stream processing on POSIX systems. Programming with DUP is similar to writing shell scripts with pipes except that filters can have multiple inputs and outputs. Furthermore, the computation can be spread across multiple computers. A distinguishing characteristic of DUP compared to other streaming languages is that filters can be written in almost any programming language. The DUP System distribution includes the runtime system and a collection of over a dozen multi-stream filters.
fpgasm creates bare-metal FPGA designs without Verilog or VHDL. Traditionally, FPGAs are built using proprietary Verilog or VHDL language implementations provided by the vendor. fpgasm is to Verilog and VHDL as assembly language is to C++. It takes you all the way to the netlist, and is not just a translator to Verilog. Because of that, the total "make" time to a working fpga is seconds, not minutes. With fewer than ten reserved words, fpgasm syntax can be mastered in a few minutes. With FPGA assembler, you can focus on understanding the FPGA substrate and how your design should map onto it (instead of figuring out large and complicated tools).
lihata is a compact textual language which can represent a tree of lists, hashes, and tables. The syntax tries to be minimal and flexible to allow formatting a lihata file to fit the context it represents. The source release contains an event and DoM parser and helper functions for maintaining lihata trees. lihata is a convenient language for both simple and complex configuration files and text representation of data files.
