The Heirloom Development Tools provide yacc, lex, m4, make, and SCCS as portable derivatives of the utilities released by Sun as part of OpenSolaris. The OpenSolaris utilities were in turn derived from the original Unix versions, and are assumed be conforming implementations of the POSIX standard.
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.
FIM (Fbi IMproved) aims to be a highly customizable and scriptable image viewer targeted at the users who are comfortable with software like the Vim text editor or the Mutt mail user agent. It is based on the Fbi image viewer and works either in the Linux framebuffer console or in the X system. It features the ability to filter the list of images with regular expressions, Vim-like autocommands, command line autocompletion and history, completely customizable key bindings, external/internal scriptability, and much more.
Hoc, the High Order Calculator, is an interpreted language for floating-point calculations. Its most basic use is as a powerful and convenient calculator, interactively evaluating expressions such as 1+2*sin(0.7). But hoc is no ordinary calculator: It also lets you assign values to variables, define your own functions, and use loops, conditionals, and everything else you'd expect in a programming language.
dwarf-ng is a small and powerful object file manipulator. With dwarf-ng, you can read, edit, and manipulate section headers, inject code or data, and create new section headers of object files. Currently, it handles object files in the PE, Mach-O, and ELF formats. For the moment, dwarf-ng only has a command-line interface. dwarf-ng is fully scriptable (as it has a scripting language), and is flexibly configurable.
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.
