C/C++ interpreter Ch 5.1, and Embedded Ch 5.1 Released
SoftIntegration, Inc. announced the availability of Ch 5.1 and Embedded
Ch 5.1. Ch is an embeddable C/C++ interpreter for cross-platform
scripting, 2D/3D plotting, numerical computing, shell programming and
embedded scripting. It supports QNX 6.3 and above.
Ch and Embedded Ch version 5.1 are the most stable release. The new
release enhances embedded Ch scripting with thread handling. It allows
you to abort an embedded Ch thread at runtime. This release includes
many fixes for bugs.
Below is a list of major Ch features.
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
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 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.
Ch toolkits and third party software support
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, and IDEs.
