debugging ruby extensions

Hello!

Is there a handy function to display messages to stdout/sterr inside
a ruby extension.

I thougth that:

if ((RARRAY(x) == NULL) || (RARRAY(y) == NULL))
{
rb_warn ("2nd and 3rd parameter must be arrays!\n");
return Qnil;
}

Would do such a thing.

BTW, is this a nice way to determine if an argument to a method
is an array of objects?

How about fprintf()? ;)

I would probably use the Check_Type() macro:

Check_Type(obj, T_ARRAY);

which raises a TypeError exception if obj is not an Array. If you want
more control over how the error is reported, instead do something like:

if (TYPE(obj) != T_ARRAY) {
/* report error here */
}

Hope this helps,

Lyle

Thank you. It is what I wanted. I just found Check_Type()
function.

Sorry for the noise.
