I have made a rough draft of a binding, but have only just begun to test
it. I don't know if I will find the time to test and debug those parts
that I don't need for my current project.
My experience so far is that more than 50% of the C primitives I've
written have conversion problems, so testing is very important. I hope
things get better with time.
However, I'm very willing to share what I have once some parts of it are
For now, a couple of interface questions:
(1) Is there a fixed rule for what methods take () as a final parameter?
Methods with side effects and no arguments, yes; but what about methods
method guess_language :
?filename:string -> ?content_type:string
-> unit -> source_language (* or raise Not_found *)
that have no side-effects and only optional arguments?
(2) On the same example: if a C method with type t may return NULL, then
we have multiple possibilities in OCaml:
(i) return "t option"
(ii) return "t", but raise Not_found if the result is NULL
(iii) if t = string, then return the empty string for NULL
A similar question applies to arguments that may be NULL. Is there a
rule that I should follow?
(3) Text iterators are wrapped in a non-mutable way, with
method forward_char : iter
returning a fresh iterator. But in gText.view there is a method
method forward_display_line_end : iter -> bool
that mutates its argument. Can this be right?
And finally: is it possible to have a C primitive that takes labelled
