Memo to use cclip-1.2

Thanks for the author of cclip. http://sourceforge.net/projects/cclip/

We will have following code in cclip, 

• main.c
  
• funcs.c
  
• clip/clip.c
  
• clip/clip.h
  

Because clip/clip.c is C++ language, I don't know how to compile it if I use C compiler.

So I modify the main.c to main.cpp, then it works.

I add some function for more alike the professional program.

For example, we won't type argument for first time use or will type "--help" or "-h" to udnerstand how to use the option.

So I add the if statement,

====================

if(argc = = 1)

{

PrintfUsage(variables);

}

====================

Then, you can just type the command, for example,

in linux,

------------------------------

$ ./main

------------------------------

In DOS,

------------------------------

$ main.exe

------------------------------

The screen will show simple information of usage,

===================================

C:\>main.exe

USAGE : main [ options] +src                  Default

-i  inputdata     Load the input data            XXXX

-i  inputdata     Load the input data            XXXX

-i  inputdata     Load the input data            XXXX

-i  inputdata     Load the input data            XXXX

===================================

How to add options?

1. modify opt options[NUM_OPTS] in clip.c
2. include right location of your new function
3. modify #define NUM_OPTS 6

opt options [NUM_OPTS] = {

{ "f", 1, SHORT, Givingformat },

{ "o", 1, SHORT, SaveResult },

{ "i", 1, SHORT, LoadFile },

{ "d", 0, SHORT, display_input_data },

{ "help", 0, LONG, PrintInfo },

{ "h", 0, SHORT, PrintInfo },

};

Comparing with the usage information,

{ "f", 1, SHORT, Givingformat }means -f argument1 to active subprocedure Givingformat (  ).

{ "help", 0, LONG, PrintInfo }means --help without argument to active subprocedure PrintInfo(  ).

If you need to the options with 2 or more arguments, modify the 2nd value to be the integer you want.

For example, "--G goal1 goal2 goal3", means { "G", 3, LONG, GOAL }.

NUM_OPTS must be correct with the number of entry in options [  ].

If you subprocedure is not in funcs.c, you have include it right.

For example, 

#include "../funcs.c"

#include "../goal.c"

Content in goal.c will be like,

int GOAL(char *args [  ])

{

       printf("argument1 is %s, argument2 is %s, argument3 is %s",args[0], args[1], args[2]);

       return 0;

}

It should be workable.

Then print "argument1 is goal1, argument2 is goal2, argument3 is goal3" on the screen.
