Ch 4.5 is out. (

Ch is a C/C++ interpreter for cross-platform scripting, 2D/3D plotting,
numerical computing, shell programming and embedded scripting.

This new release includes the following major product enhancements:

    * More C++ features.

    * Simplified interface with C/C++ libraries. The existing
        binary C/C++ libraries can be turned into Ch modules easily.

    * Simplified embedding a Ch scripting engine into applications.

    * File name completion using a tab key in a Ch command shell.

    * Command history retrieval in both Unix and Windows

    * Many new features and bug fixes.

Here is a little introduction about Ch.

* C/C++ interpreter

Ch supports 1999 ISO C Standard (C99) and C++ classes. Ch also supports
many industry standards with over 8,000 functions including POSIX,
socket/Winsock, X11/Motif, OpenGL, ODBC, C LAPACK, GTK+, Win32, and CGI.
Functions in static or dynamical binary C/C++ libraries can be executed
interpretively in scripting without re-compilation using Ch SDK.

* Shell programming and cross-platform scripting

Ch shell is C compatible shell while C-shell (csh) is a C like shell. Ch is
an interpretive implementation of C, similar to Unix/MS-DOS shells. Ch in
Windows includes over 100 commonly-used Unix commands for portable shell
programming. Ch can also be used as a login shell just like sh, csh and ksh.
Ch bridges the gap between the C language and shell languages. With its
built-in string type and many enhanced scripting features, Ch is an
alternative to other scripting languages for automating repetitive tasks,
regression test, and hardware testing with direct interface to hardware.

* 2D/3D plotting and numerical computing

Ch supports 2D/3D graphical plotting, C LAPACK, high level numeric
Ch has built-in 2D/3D plotting support, generic mathematical functions and
computational arrays for linear algebra and matrix computations, and
high-level numerical functions for linear systems, differential equation
solving, Fourier analysis, curve fitting, etc. For example,
linear system equation b = A*x can be written verbatim in Ch.

Ch numerical extensions are the best choice for numerical computing in
C/C++ domain With SoftIntegration graphical library (SIGL), the same
using 2D/3D plotting features can be executed in Ch or compiled using C
++ compilers without any modification.

Ch is ideal for rapid application development and deployment. For
example, a
Control System Toolkit for design and analysis of linear time-invariant
control systems developed in Ch is available.

* Interface with binary C/C++ libraries

Ch SDK 4.5 can easily integrate the existing C/C++ libraries as part of
Ch sripting module. Functions and classes in C/C++ static or dynamical
libraries can be invoked in a Ch script file or Ch command shell.

* Embeddable scripting

Ch 4.5 is optimized for embedded scripting. Embedded Ch allows users to
embed Ch into other C/C++ application programs and hardware. It is ideal
for open-architecture application integration. With Embedded Ch, C/C++
applications can be extended with all features of Ch. It allows execution
of C/C++ scripts generated dynamically on-line. Embedded Ch has a small
footprint. The pointer and time deterministic nature of the C language
provides a perfect interface with hardware in real-time systems.

* Ch toolkits and third party software support

Ch supports an increasing number of third party software applications. It
includes Ch Control toolkit, Ch NAG Statistics Package, Ch CGI toolkit, Ch
ODBC toolkit, Intel OpenCV for computer vision and image processing,
National Instruments' data acquisition toolkit NI-DAQ and motion control
toolkit NI-Motion, Barret Technology's Barret Hand robotic manipulator
control, and Perl Compatible Regular Expressions, as well as
IDE (Integrated Development Environment).

* Pricing and Availability

Ch for Windows, Linux, Mac OS X, Solaris, and HP-UX is available. Ch
Standard Edition is free for both commercial and non-commercial uses. Ch
Professional Edition is free for academic use and costs $399 for personal
or commercial use.
