The Tecla library provides programs with interactive command line editing facilities, similar to those of the Unix tcsh shell. It supports recall and editing of previously entered command lines, TAB completion of file names and application specific tokens, and in-line wild-card expansion of filenames. The optionally reentrant modules which perform TAB completion and wild-card expansion are also available separately for general use. The library is smaller, more modular, makes more efficient use of the heap, and has a less restrictive license than GNU readline.
PyObjC is a bridge between Python and Objective-C that allows full featured Cocoa applications to be written in pure Python. It can also be used with other Objective-C class libraries, as well as C and C++ source. The installer package includes a number of Project Builder templates and Python syntax coloring files. It supports full introspection of Objective-C classes and direct invocation of Objective-C APIs from the interactive interpreter.
The Crow Designer is a visual editor for building graphical user interfaces. Interfaces are saved in files of the GuiXml format and may be involved in applications by means of the GuiLoader library. During editing, the following instruments are available to a user: a palette of GUI controls, an object tree, an editor canvas, and a hierarchical property explorer. The property explorer allows you to work with nested objects and arrays as well as with several selected objects simultaneously. The designer uses widgets of the GTK+ library as a GUI control kit.
Ripple is a dedicated scripting language for the Semantic Web. Ripple programs not only query the Semantic Web, but also reside within it as RDF data structures, forming a global network of interlinked programs. Ripple is best classified as a relational stack language, closely related to functional stack languages such as Joy, Factor, and Cat. As a Semantic Web interface, Ripple is a fast, text-based linked data crawler and browser with all of the flexibility of a Turing-complete programming language.
