ClearSilver is a high-performance, powerful, and language-neutral HTML template system. It enforces a separation between presentation code and application logic which makes writing, debugging, and maintaining Web pages easier. It can be used from C/C++, Python, Perl, Java, and Ruby. It runs on Windows and Unix.
ACDK is a development framework with a similar target of Microsoft's .NET or Sun's ONE platform, but it uses C++ as a core implementation language. It implements the standard library packages, including acdk::lang, acdk::lang::reflect, acdk::util, acdk::io, acdk::text (including regexpr), acdk::net, acdk::sql, acdk::xml, and more. Flexible allocator/garbage collection, threading, and Unicode are implemented in the core of ACDK. Extensions make C++ objects available for reflection, serialization, aspect-oriented class attributes, and [D]ynamic [M] ethod [I]nvocation. This DMI acts as an universal object oriented call interface to connect C++ with scripting languages (Java, Perl, Tcl, Python, Lisp, Visual Basic, and VBScript) and standard component technologies (CORBA and COM).
mxDateTime is a Python module designed to do complex date/time handling with Python. It includes new Python extensions objects for storing and working with date and time as well as date/time parsers, access to the NIST time services and many different conversion routines to other well-known date/time standards such as ISO, ARPA, COM dates, Unix ticks, JDN, MJD, TJD and others.
pythonOCC is a 3D CAD/PLM development library for the Python programming language. It provides 3D hybrid modeling, data exchange (support for the STEP/IGES file format), GUI management support (wxPython, PyQt, python-xlib), parametric modeling, and advanced meshing features. pythonOCC is built upon the OpenCASCADE 3D modeling kernel and the salomegeom and salomesmesh packages. Some high level packages (for parametric modeling, topology, data exchange, webservices, etc.) extend the builtin features of those libraries to enable highly dynamic and modular programming of any CAD application.
