Ch is an embeddable C/C++ interpreter for cross-platform scripting, 2D/3D plotting, numerical computing, and embedded scripting.
This new release added Embedded Ch function callback features, more C99 features, and powerful new plotting capabilities such as smooth surface mesh etc. Ch Professional Edition is now ported for QNX.
DAVIS, California, October 16, 2005 - SoftIntegration, Inc. today
announced the availability of Ch 5.5 and Embedded Ch 5.5. Ch is an
embeddable C/C++ interpreter for cross-platform scripting,
2D/3D plotting, numerical computing, shell programming and
embedded scripting.
Ch and Embedded Ch version 5.5 are the most stable release. The new
release mainly added Embedded Ch function callback features, more
C99 features, and powerful new plotting capabilities, Ch Professional
Edition supports smooth surface mesh for 3D plotting. The view angle
of 3D plots can be changed and coordinates of 2D plots can be tracked
by a mouse. Ch Professional Edition is now supported in QNX. This
release also fixed many reported bugs.
"Ch is an excellent environment for research and teaching. I use it
for research and teaching on mechatronics and control," said Professor
David Auslander at the University of California at Berkeley. "To me the
main advantage of an interpreter is portability. Ch allows C programs to
be executed portably across different platforms. In addition, a major
advantage of Ch is its user-friendly mathematical and graphical
infrastructure. Getting that in C, C++ or Java requires assembling a
large collection of libraries from a variety of sources, each with its
own quirks. I am very impressed with the salient graphical plotting
capabilities in Ch version 5.5. They are easy to use and very useful
for applications in engineering and science."
"We greatly appreciate the power and flexibility of a C interpreter
bring to the simulation and design of power electronics and motor
drive systems," added Hua Jin, president of Powersim Inc. "PSIM from
Powersim Inc. is specifically developed for simulation and design of
power electronics and motor drive systems. An embedded C interpreter
makes it extremely easy to write C code in PSIM without the need of a
separate C compiler. The response from our customers on the C Script
Block in PSIM, powered by the Embedded Ch interpreter, is very good.
Thank you for a well-developed product."
Below is a list of Ch major features.
* 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, XML, and
CGI. With built-in Ch SDK, functions in static or dynamic binary C/C++
libraries can be executed in Ch script file or Ch command shell without
re-compilation. Programs can also be developed and executed using a
number of user-friendly Integrated Development Environment (IDE)
such as ChSciTE.
* Embeddable scripting
Ch is easy and simple for embedded scripting. Embedded Ch allows users
to embed Ch into C/C++ application programs and hardware as a
scripting engine. 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. Embedded Ch supports multi-threading and
has a small footprint. The pointer and time deterministic nature
of the C language provides a perfect interface with hardware in
real-time systems.
* 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 200 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
Ch graphical extensions are the best choice for plotting in the C/C++
domain. Ch supports high-level 2D/3D graphical plotting. Two and three
dimensional graphical plots can be very easily accomplished. Plots in
Ch can be generated from data arrays or files, and can be displayed
on a screen, saved as an image file in a variety of ifferent file
formats, or output to the stdout stream in a proper image format
for display in a Web browser through a Web server. 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.
* Numerical computing
Ch numerical extensions are the best choice for numerical computing in
the C/C++ domain. Ch has built-in generic mathematical functions and
computational arrays for linear algebra and matrix computations. It
contains 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 supports C LAPACK,
GNU Multiple Precision Arithmetic Library, and GNU Scientific Library.
Applications written using these libraries can be executed in Ch
or compiled using C compilers without any modification.
* Ch toolkits and third party software support
Ch is ideal for rapid application development and deployment. Ch supports
an increasing number of third party software applications. It includes Ch
Control toolkit, Ch Mechanism Toolkit, Ch NAG Statistics Package,
Ch CGI toolkit, Ch ODBC toolkit, Ch XML toolkit, ChExcel for manipulating
Microsoft Excel in C/C++ scripts, Intel OpenCV for computer vision,
ImageMagick for image processing, National Instruments' data
acquisition toolkit NI-DAQ and motion control toolkit NI-Motion.
* Pricing and Availability
Ch and Embedded Ch for Windows, Linux x86, Linux PPC, Mac OS X, Solaris,
HP-UX, FreeBSD and QNX Neutrino RTOS are available. Ch Standard
Edition is free for both commercial and non-commercial uses in all
platforms. Ch Professional Edition is free for academic use and
costs $199 for personal or commercial use. To purchase Embedded Ch,
