Some questions about wrapping types

Johann 'Myrkraverk' Oskarsson writes: You can return a type derived from Lisp_Opaque object, which is just a blob of memory containing the data. That's all you need to do if it just gets passed to other libClang objects. Turning it into an integer or the like is a bad idea, as that means you can't type check objects passed to libClang interfaces. Property lists are application-specific, user-supplied attributes. If the cursor type doesn't need them you don't need to implement it. I would most likely use symbols. Whether to use keywords is a matter of taste. I probably wouldn't. Using integers isn't a great idea; you can't type check them. If you need to allow users to write programs where the ints in the underlying enum are directly input, that can be done with a helper program at the Lisp level. But I would not support that -- I'd tell the user to write their own int-to-enumerator helper function if they want that. Creating a separate enum type seems like overengineering; if you want to introspect the set of enumerators, a defconst at Lisp level seems sufficient. If you really want to, you can create that list read-only at the C level in your module. _______________________________________________ XEmacs-Beta mailing list XEmacs-Beta(a)xemacs.org http://lists.xemacs.org/mailman/listinfo/xemacs-beta
