Ch interpreter

Encyclopedia : C : CH : CHI : Ch interpreter

Ch, pronounced as C H, is an embeddable C/C++ interpreter. Ch is designed for using one C compatible language for all programming tasks.

Ch programming language extends C and C++ for scripting, numerical computing and 2D/3D plottings and embedded scripting. It can run in Windows, Linux x86, Linux PPC, Solaris, HP-UX, Mac OS X, FreeBSD and QNX.

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 supported. Wide characters in Addendum 1 for C90 is also supported.

Embeddable scripting

As a C/C++ interpreter, Ch can be used as a scripting engine for your applications. It extends your applications with C compatible scripting language.

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 
int main()

Note: #!/bin/ch is optional.

Numerical computing in Ch

#include 
#include 
int main() ;
array double B[3][2]
printf("A= \n%f \n", A+A);
B = 2*transpose(A);
printf("B= \n%f \n", B);
}

The output is:

A=
2.000000 4.000000 6.000000
8.000000 10.000000 12.000000
B=
2.000000 8.000000
4.000000 10.000000
6.000000 12.000000

Shell programming

Find and compile all .c files into .o in the current directory when the .o is old or absent.

#!/bin/ch
#include <sys/stat.h>
struct stat cstat, ostat;
string_t c, o;
foreach (c; `find . -name "*.c"`)

}

2D/3D plotting in Ch

To plot a sine wave:

#include 
#include 
int main()
