I see.. only rb_require(). BTW what is a frame?


Im writing a tutorial on embedding. The section on "initialization".
What should I write:  use ruby_script() it does something ?
http://metaeditor.sourceforge.net/embed/


I tried rb_load() .. but I don't see "embed" in the backtrace, why ?

> ./a.out
hello
        from ./test.rb:2
ERROR #<RuntimeError: out>
> cat main.cpp
#include <ruby.h>
#include <iostream>
using namespace std;

VALUE myfunc(VALUE) {
        //rb_require("test.rb", 0);
        rb_load(rb_str_new2("test.rb"), Qtrue);  // no "embed" backtrace?
        return Qnil;
}

int main(int argc, char *argv[]) {
        ruby_init();
        ruby_init_loadpath();
        ruby_script("embed");
        int error;
        rb_protect(myfunc, 0, &error);
        if(error) {
                VALUE err = rb_inspect(ruby_errinfo);
                rb_backtrace();
                cout << "ERROR " << StringValuePtr(err) << endl;
        }
        return 0;
}
