Hi list !
I am *very* happy to announce a major leap forward for the dubLua
bindings generator for C++ code. The most important enhancement is the
support for 'super' and 'bind' settings in the class documentation:
/** Foobar is a special widget that flashes with advertisement about
lottery winnings.
*
* @dub super: 'QObject, QWidget'
* bind: 'Foobar.yml'
*/
class Foobar : public QWidget {
public:
Foobar() {}
void size();
};
When this is parsed by Doxygen and the bindings are generated by dub,
all methods declared for QObject and QWidget in their respective
headers (or pseudo-headers) will be bound to the Foobar class.
Moreover if you want to have some more Luaish bindings (return
multiple values, work on tables, etc), you can define the binding in a
yaml file (in the same directory as the header):
Foobar.yml
lua:
# dub automatically detects and parses the arguments and checks their type
# we only need to write the body
doSomething: |
lua_pushnumber(L, self->width());
lua_pushnumber(L, self->height());
return 2
This might no seem very impressive but it really makes bindings with
some customization to existing libraries (Qt) much easier...
Cheers,
Gaspard
==== What is dub ?
https://github.com/lubyk/dub
Dub is a Ruby gem that creates Lua bindings by reading the output from
Doxygen (a C++ header parser). It is used extensively in Lubyk to
create all the bindings. The documentation is so bad currently that
either you manage to read the code in lubyk
(https://github.com/lubyk/lubyk/blob/master/modules/bind.rb) or you
can just email me for help...
