c-script provides the function of script language for c++.

This is made for throwaway, short, and fast programs.
This gives weight to runtime speed for solving image processing problems.

You needs only script to run your program.
Makefile and other build tool are not needed.

This supports following functions.

1. Shebang
2. Cache : When compiled once, executable cache is used the next time.
3. Debugger(gdb,ddd,emacs,VC++) and reasonable compile error message.
4. #pragma : Compilation option is controlled by #pragma.
5. Image manipulation : This can read and write bmp, jpg and png.
6. Matrix function like eigen: This uses blas and lapack.
7. Drawing graph funtion by gnuplot
8. c++, cuda, c, obj-c and c# are supported.

Set path for root directory of this program.
export PATH=$PATH:program_root

Case1:

c-script my_cpp_program.cpp

Case2:
1.Write script

For example,

#!/usr/bin/env c-script
int
main(){
  printf("hello world\n");
  return 0;
}

2.Chmod

chmod +x above_cpp_program.cpp

3.Run

./above_cpp_program.cpp

Usage: c-script [options] script-file [script-options]
 -no_chk_main  disable of main-function-insertion
 -nocache      compile the program everytime
 -d            run the program under the gdb
 -gdb          run the program under the gdb
 -ddd          run the program under the ddd
 -vc           run the program under the visual studio
 -show         output code after preprocess
 -cmd          output compiler-options
 -clean        remove cache of both exe and source

#pragma c-script:src  "file1" "file2" ..
 compile with "file1" "file2" ..
#pragma c-script:opt  "additional compile options"
 add compile options 
#pragma c-script:eval "Run perl-expression"
 
#pragma c-script:do   "Run perl-script"
#pragma c-script:cc   "compiler command name(default:g++)"
#pragma c-script:libs "liked library options"
#pragma c-script:no_default_header

init/init.pl
init/suffix_cu.pl
init/suffix_cs.pl
init/suffix_m.pl
$HOME/init.pl
$HOME/.c-script/cache

This runs following steps.

1. Read initialization script for reading compilation paramater.
2. Generate compiled code (For example, header like '#include' is added.)
3. Compile
4. Run complied binary
