aime is a simple, C-like programming language and an interpreter, both designed to be embeddable in applications. The language is straightforward, trivial, and direct. Its syntax is simpler than that of C, while still providing for full object management, higher order functions, and references. The interpreter is secure and expressive, allowing comprehensive control over program execution and providing powerful methods of application integration.
Seed7 is a general purpose programming language. It is a higher level language compared to Ada, C++, and Java. In Seed7, new statements and operators can be declared easily. Functions with type results and type parameters are more elegant than a template or generics concept. Object orientation is used when it brings advantages and not in places when other solutions are more obvious. Although Seed7 contains several concepts of other programming languages, it is generally not considered as a direct descendant of any other programming language.
LavaPE is a programming environment for the experimental object-oriented programming language Lava. It replaces text editing with structure editing, thereby preventing all syntactic and many semantic errors. The pure point-and-click nature of Lava programming and the concise representation of programs as declaration trees with small chunks of executable code simplify programming, and ease comprehension.
FIM (Fbi IMproved) aims to be a highly customizable and scriptable image viewer targeted at the users who are confortable with software like the Vim text editor or the Mutt mail user agent. It is based on the Fbi image viewer and works in the Linux framebuffer console (it is not an X program). 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.
Styx is a scanner/parser generator designed to address some shortcomings of the traditional lex/yacc combination. It has unique features like automatic derivation of depth grammar, production of the derivation tree, including it's C interface, preservation of full source information, pretty printing to faciliate source-source translation, and persistence to aid rapid interpreter writing. It also supports reentrancy. Styx works well under several different OSes, including serveral Unixes, DOS, and Windows.
MDK (MIX Development Kit) provides tools for developing and executing, in a MIX virtual machine, MIXAL programs. The MIX is Donald Knuth's mythical computer, described in the first volume of The Art of Computer Programming, which is programmed using MIXAL, the MIX assembly language. MDK includes a MIXAL assembler (mixasm), a MIX virtual machine (mixvm) with a command line interface, a Guile-based virtual machine (mixguile), a GTK+ based GUI (gmixvm), and a mixvm-Emacs interface (mixvm.el). MDK utilities are extensible using Scheme.
