grun

GTK+ based Run dialog

gRun is a GTK+ based Run dialog that closely resembles the Windows Run dialog, just like xexec. It has a intelligent history mechanism and a dual level fork() mechanism for launching the application in its own process. gRun also has support for launching console mode application in an XTerm as well as associations for file types. gRun is much more powerful than xexec, looks a lot better, and has the big advantage that you can start typing a command without having to mouse-click into the text field. gRun is especially useful if you do not use the GNOME desktop which has a built-in run command, and if you use a window-manager (e.g. IceWM) where you can define a keyboard shortcut (e.g. Alt-F2) for staring gRun.

ANTLR Parser Generator

ANTLR (ANother Tool for Language Recognition) is a powerful parser generator for reading, processing, executing, or translating structured text or binary files. It's widely used to build languages, tools, and frameworks. From a grammar, ANTLR generates a parser that can build and walk parse trees.

language tool for constructing recognizers, compilers etc

ANTLR, ANother Tool for Language Recognition, (formerly PCCTS) is a language tool that provides a framework for constructing recognizers, compilers, and translators from grammatical descriptions containing C++ or Java actions [You can use PCCTS 1.xx to generate C-based parsers]. Computer language translation has become a common task. While compilers and tools for traditional computer languages (such as C or Java) are still being built, their number is dwarfed by the thousands of mini-languages for which recognizers and translators are being developed. Programmers construct translators for database formats, graphical data files (e.g., PostScript, AutoCAD), text processing files (e.g., HTML, SGML). ANTLR is designed to handle all of your translation tasks.
