Ch (computer programming)
Ch, pronounced as C H, is an embedded C/C++ interpreter. It extends C and C++ for scripting capability, numerical computing and cross platform 2D/3D plottings.
Features
C/C++ compatible interpreter
Ch supports 1999 ISO C Standard (C99) and C++ classes. It is superset of C with C++ class. C99 major features such as complex numbers, variable length arrays (VLAs), IEEE-754 floating-point arithmetic, generic mathematical functions in C99 are suppported. Wide characters in Addendum 1 for C90 is also supported.
Embeddable scripting
As a C/C++ interpreter, it is a nice fit as an embedded scripting engine for C/C++ applications.
Shell programming and cross-platform scripting
Ch is a C-compatible shell similar as C-shell (csh). It can be used as login shell as well. Ch has a built-in string type for auto memory allocation and de-allocation. It makes scripting easier.
2D/3D plotting and numerical computing
Ch has built-in 2D/3D graphical plotting features and computational arrays for numerical computing. Linear system equation b = A*x can be written verbatim in Ch.
Examples
"Hello, world!" in Ch
There are two ways to run Ch code. One is:
#!/bin/ch
printf("Hello world!\n");
Another is:
#!/bin/ch
#include <stdio.h>
int main() {
printf("Hello world!\n");
}
