For 'module' and 'require' look into lua loadlib.c
Change findfile() to locate modules
And look at loaders loader_Lua, loader_C etc
Maybe you can setup some hook functions to redirect calls into wxLua -

Subject: [Wxlua-users] Add LUA_PATH to lua for require (Ray)
I saw you added some functions to get the LUA_PATH. I was wondering
if, after looking at some of the code, you have any ideas about how to
get wxLuaFreeze to override "require" so that it can be forced to look
into an attached zip file instead of the disk?
Currently wxLuaFreeze just attaches a single lua program to the end of
a C++ executable, but we can change that to attach a zip file with all
the necessary modules/libs and use wxZipFilesystem (or whatever it's
called) to browse it. We can't just override os.open and whatnot since
the lua program may actually want to read from the disk.
Thanks,
John Labenski

Unfortunately, I have not. I was waiting for things to settle down, which they seem to have. But my situation has recently changed. The startup that was funding Emma has fallen on tough times and cancelled my project. So I will be moving to a REAL job and Emma will become a hobby. But I hope to switch over to the new code base soon. I really believe the declarative approach that Emma brings is really valuable to GUI apps using wxLua. On that subject, I was wondering about a couple of things. Does your incarnation of wxLua include the Scintilla widget (StyledTextWidget I think it is referred to as)? Also, what about dockable windows? I know that there are at least 3 solutions for this for wxWidgets. I tried to integrate the FL stuff into a different project I was doing a couple of years ago and found it pretty buggy. Even now, it is supposedly part of wxWidgets, but there is little documentation about it. wxAUI looks promising and claims to be the next "standard" for wxWidgets. Then there is DockIt, which I know little about. Any support for these in wxLua? Good luck on your upcoming release! -- chris marrin ,""$, ch...@ma... b` $ ,,.

We hope to have a release at the end of this week or probably next week and I was going to post it to all the different places, wxWidgets, lua.org, scintilla (has link to old dead site). I also *still* have to get around writing some more docs about programming in wxLua and also in C++ using wxLua. Have you tried the latest wxLua using 5.1? You had some fixes and what not from before which I tried to merge in. I think I got them all, but I forget about the event handling change you wanted. I think I had another way in mind that was equivalent, but a little less intrusive. Let us know if there's any other improvements and obviously patches for them would be great.

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

That sounds better. I guess I forgot, I've changed it and then
discovered that I had to do a little more tweaking since different
overloaded functions can have their own #if conditions. Everything
seems to work now and I'll add some more of the overloaded functions
tonight.

The overload tag arglist should be the class tag - I thought
s_wxluaarg_UserData should only be for unknown raw user data
static int LUACALL wxPoint_constructor(lua_State *L)
{
// function overload table
static WXLUAMETHOD overloaded_methods[] =3D
{
{ LuaConstructor, "wxPoint", wxPoint_constructor1, 2, 2, {
&s_wxluaarg_Number, &s_wxluaarg_Number, 0 } },
{ LuaConstructor, "wxPointCopy", wxPointCopy_constructor, 1, 1,
{ &s_wxluatag_wxPoint, 0 } },
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
};
static int overloaded_methodCount =3D
sizeof(overloaded_methods)/sizeof(overloaded_methods[0]);
wxLuaState wxlState(L);
return wxlState.CallOverloadedFunction(overloaded_methods,
overloaded_methodCount);
}

All done! I hope I didn't step on your toes, but I had some free time
and figured I've give adding it to genwxbind.lua a shot.
You have to use a new "%overload" tag in the bindings. This is because
as you go through the .i files you don't know if you'll have duplicate
functions until after you've already written the binding code for the
earlier function. So if you had wxPoint(int, int) and wxPoint(const
wxPoint&) and *didn't* use the "%constructor" tag (or for members the
%rename tag) there would be two functions
wxPoint_constructor(lua_State*) and obviously you get a compile error.
I track these and just add a number from 1 to whatever so there's no
name clashes. Additionally the WXLUAMETHOD map would have already been
created with a "wxPoint" constructor in it and you'd never get to the
overload function.
Currently I've tested it with the wxPen constructors and
wxPen::SetColour and it seems to work nicely. You can see the code in
modules/wxbind/src/gdi.cpp bindings/wxwidgets/gdi.i.
I had to tweak the args in wxLuaState::CallOverloadedFunction since if
you call a member function the "self" is the first arg and we don't
want that. Other than that it works great and the error message is
really nice.
For testing you can use wxLuaEdit and try these out
a =3D wx.wxPen(wx.wxRED, 1, 1)
b =3D wx.wxPen(a)
b:SetColour("RED")
print(b:GetColour():Red())
b:SetColour(0,0,0)
print(b:GetColour():Red())
print(a:GetColour():Red())
255
0
255
-- test out a mistake
b:SetColour(1,2,3,4)
Err: lua: Error while running chunk
wxLua overloaded function SetColour(number, number, number, number)
has invalid argument 4 on method 01

01. SetColour(number, number, number)
02. SetColour(string)
03. SetColour(userdata)

All done! I hope I didn't step on your toes, but I had some free time
and figured I've give adding it to genwxbind.lua a shot.
You have to use a new "%overload" tag in the bindings. This is because
as you go through the .i files you don't know if you'll have duplicate
functions until after you've already written the binding code for the
earlier function. So if you had wxPoint(int, int) and wxPoint(const
wxPoint&) and *didn't* use the "%constructor" tag (or for members the
%rename tag) there would be two functions
wxPoint_constructor(lua_State*) and obviously you get a compile error.
I track these and just add a number from 1 to whatever so there's no
name clashes. Additionally the WXLUAMETHOD map would have already been
created with a "wxPoint" constructor in it and you'd never get to the
overload function.
Currently I've tested it with the wxPen constructors and
wxPen::SetColour and it seems to work nicely. You can see the code in
modules/wxbind/src/gdi.cpp bindings/wxwidgets/gdi.i.
I had to tweak the args in wxLuaState::CallOverloadedFunction since if
you call a member function the "self" is the first arg and we don't
want that. Other than that it works great and the error message is
really nice.
For testing you can use wxLuaEdit and try these out
a =3D wx.wxPen(wx.wxRED, 1, 1)
b =3D wx.wxPen(a)
b:SetColour("RED")
print(b:GetColour():Red())
b:SetColour(0,0,0)
print(b:GetColour():Red())
print(a:GetColour():Red())
255
0

b:SetColour(1,2,3,4)

I would overwrite it - just note how we should generate overloaded
function bindings.
I was thinking that when genwxbind.lua member.AltName ~=3D member.Name =
we
track overloads of member.Name and generate appropriate code.

I need to overwrite it to fix some issues w/ wxWidgets CVS head.
Should I keep it or just let it get overwritten?
What do the bindings look like for them, is this ok or is there some
sort of tag for it?
%class ... wxColour
wxColour(const wxString& name)
wxColour(int r, int g, int b)
wxColour(const wxColour& colour)
// and for functions
bool DoStuff(int i)

I did a small fix in line above:
// wxT("") is required instead of wxEmptyString otherwise GCC says:
// ../modules/wxbind/src/wx_bind.cpp:52: error: operands to ?:
have different types
wxString value =3D (argCount >=3D 1 ? =

and just committed it; however I wonder: wx_bind.cpp is regenerated by
genwxbind.lua... so, adding this code directly in wx_bind.cpp doesn't
mean that next time it's regenerated, the code will be lost ?

Some changes in wxWidgets CVS head are causing more problems. They've
removed wxRED_PEN and and the rest of the objects and use a wxStockGDI
class to get them so that we get "error: non-lvalue in unary `&'" on
these objects, see wxRED_PEN below for code.
This is new wxWidgets code
#define wxRED_PEN wxStockGDI::GetPen(RED_PEN);
static wxPen* wxStockGDI::GetPen(int type);

My question is why do we have objPtr and pObjPtr in WXLUAMETHOD? When
would pObjPtr be needed instead of just assigning the pointer value as
is to objPtr? The fix to the above is not terrible, a little annoying,
but I guess I'd like to understand this first and remove pObjPtr is
it's not needed.
Thanks,

I did a small fix in line above:
// wxT("") is required instead of wxEmptyString otherwise GCC says:
// ../modules/wxbind/src/wx_bind.cpp:52: error: operands to ?:
have different types
wxString value = (argCount >= 1 ? lua2wx(wxlState.GetStringType(1))
: wxT(""));
and just committed it; however I wonder: wx_bind.cpp is regenerated by
genwxbind.lua... so, adding this code directly in wx_bind.cpp doesn't
mean that next time it's regenerated, the code will be lost ?
