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.
fsc2 is a program for controlling spectrometers. Experiments are done by interpretation of scripts written in a simple language, EDL. Devices are handled via modules in order to allow easy integration of new devices. More than 50 devices are supported, connected via serial port, GPIB, LAN, or USB as well as data acquisition cards, etc. The state of an experiment can be remotely monitored via a built-in Web server.
