#### mrb_range_new
|
|
```C
|
|
mrb_value mrb_range_new(mrb_state*, mrb_value, mrb_value, mrb_bool);
|
|
```
|
|
Initializes a Range. The first mrb_value being the beginning value and second being the ending value.
|
|
The third parameter is an mrb_bool value that represents the inclusion or exclusion of the last value.
|
|
If the third parameter is 0 then it includes the last value in the range. If the third parameter is 1
|
|
then it excludes the last value in the range.
|
|
C code
|
|
```C
|
|
#include <stdio.h>
|
|
#include <mruby.h>
|
|
#include "mruby/range.h" // Needs the range header.
|
|
#include "mruby/compile.h"
|
|
|
|
int main(int argc, char *argv[])
|
|
{
|
|
mrb_int beg = 0;
|
|
mrb_int end = 2;
|
|
mrb_bool exclude = 1;
|
|
mrb_value range_obj;
|
|
mrb_state *mrb = mrb_open();
|
|
if (!mrb) { /* handle error */ }
|
|
FILE *fp = fopen("test.rb","r");
|
|
range_obj = mrb_range_new(mrb, mrb_fixnum_value(beg), mrb_fixnum_value(end), exclude);
|
|
mrb_value obj = mrb_load_file(mrb,fp);
|
|
mrb_funcall(mrb, obj, "method_name", 1, range_obj);
|
|
fclose(fp);
|
|
mrb_close(mrb);
|
|
return 0;
|
|
}
|
|
```
|
|
Ruby code
|
|
```Ruby
|
|
class Example_Class
|
|
def method_name(a)
|
|
puts a
|
|
puts a.class
|
|
end
|
|
end
|
|
Example_Class.new
|
|
```
|
|
This returns the following:
|
|
```Ruby
|
|
0...2
|
|
Range
|
|
```
