SoftIntegration, Inc. just released Ch 4.7, Ch SDK 4.7 and Embedded Ch
4.7. Ch is an embeddable C/C++ interpreter for cross-platform scripting,
2D/3D plotting, numerical computing, shell programming and embedded
Ch, Ch SDK and Embedded Ch version 4.7 are the most stable release. They
are significantly improved for embedded scripting. Ch shell is more
compatible with C shell in both command mode and shell programming.
Major product enhancements for Ch SDK and Embedded Ch include
input/output redirection, obtaining complete information about variables
and functions in a Ch script, and interfacing functions with a variable
number of arguments. Thirty-six new APIs are added in Ch SDK and
Embedded Ch for easier interface with binary C/C++ libraries and
This new release supports Borland compiler for embedded scripting.
Sample code using VC++, VC.NET, and Borland compiler to embed Ch into
C/C++ applications are included in the distribution.
* 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, advanced high-level
numerical functions. Ch has built-in 2D/3D plotting support, generic
mathematical functions and computational arrays for linear algebra and
matrix computations, and advanced high-level numerical functions for
linear systems, differential equation solving, integration, non-linear
equations, 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
the C/C++ domain. With SoftIntegration graphical library (SIGL), the
same program 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 4.7 can easily integrate existing C/C++ libraries as part of Ch
scripting modules. Functions and classes in static or dynamical
libraries can be invoked in a Ch script file or Ch command shell.
* Embeddable scripting
Ch 4.7 is optimized for embedded scripting. Embedded Ch allows users to
embed Ch into other C/C++ application programs and hardware. It is ideal
