[Wxlua-users] Added %operators to bindings

[John L. <jla...@gm...>]

I've added the %operator tag to the bindings, just for wxPoint for
now. Since lua has only a limited subset of operators (no +=3D, ++, etc)
I've just made them into functions, which even if we wanted to
override the lua operators in the metatable we'd still use the
functions.

They take the same semantics as C++ class operator functions, just
prepend %operator to it.

    operators["=3D"]  =3D "op_assign"
    operators["=3D=3D"] =3D "op_eq"
    operators["!=3D"] =3D "op_ne"
    operators["<"]  =3D "op_lt"
    operators[">"]  =3D "op_gt"
    operators["<=3D"] =3D "op_le"
    operators[">=3D"] =3D "op_ge"

    operators["|"]  =3D "op_or"
    operators["&"]  =3D "op_and"
    operators["||"] =3D "op_lor"
    operators["&&"] =3D "op_land"
    operators["!"]  =3D "op_not"

    operators["++"] =3D "op_inc"
    operators["--"] =3D "op_dec"

    operators["+"]  =3D "op_add"
    operators["-"]  =3D "op_sub"
    operators["*"]  =3D "op_mul"
    operators["/"]  =3D "op_div"

    operators["+=3D"] =3D "op_add_eq"
    operators["-=3D"] =3D "op_sub_eq"
    operators["*=3D"] =3D "op_mul_eq"
    operators["/=3D"] =3D "op_div_sub"
    operators["%=3D"] =3D "op_mod_sub"
    operators["&=3D"] =3D "op_and_eq"
    operators["|=3D"] =3D "op_or_eq"
    operators["^=3D"] =3D "op_xor_eq"

For example:

a =3D wx.wxPoint(1,2)
b =3D wx.wxPoint(1,2)
print(a:op_eq(b))
b =3D wx.wxPoint(1,3)
print(a:op_eq(b))
c =3D wx.wxSize(3,3)
d =3D b:op_add_eq(c)
print(d:GetX(), d:GetY())

true
false
