pyratemp is probably (one of) the smallest complete template-engines for Python (with about 500 LOC). It has a very small set of special syntax in the templates. This reduces complexity and the probability of bugs and lead to an easy-to-use and intuitive user-interface. It uses embedded Python-expressions (in a "sandbox"), is well documented, has full Unicode-support, and produces very good error-messages, which is very useful when creating new templates.
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.
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.
Toolbar Icons is a collection of free toolbar icons. All icons are available as (Inkscape) SVG files. OMake build scripts that automatically generate PNG files of basically any size (using Inkscape) are included. PNG files in a few default sizes (16 x 16, 24 x 24, 32 x 32, and 256 x 256) are prepared in .tar.gz archives.
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.
