I am also a big fan of single executable programs, but unfortunately
what you ask for is difficult if not impossible.

1) You can embed raw data into wxLua as a table of integers for each
byte. We would probably need to add functions catered to how to use
the data for a specific purposes.

2) Embedding dlls is not so easy I think. I have toyed with the idea
of using the wxWidgets wxZipFileSystem to zip up data and then use it.
I do not know if you can do this with dlls though. If this were
possible wxLuaFreeze could take advantage of that, but unfortunately I
do not have time these days to look into it.

You may want to do a web search for how to embed dlls in C++ and how
use them to see if it's even possible or reasonably easy to do. If so,
we can go from there to see just what it would take to add the same
functionality in wxLua.

I have tried this in the minimal.cpp sample using MS VS2005 and (c)
does work in the about dialog there. Why it doesn't work in wxLua is
probably because of the wx2lua and lua2wx string conversion functions
in modules/wxlua/include/wxlstate.h.

This has been discussed before, but with no resolution. The problem is
that people make suggestions for changes to make it work for them, but
would break things for other people. I do not understand much about
unicode or even UTF8 strings other than a cursory knowledge so I
cannot help much. I presented a summary of the different suggestions
on the mailing list, but nobody seemed to know definitely what was
right.

see "wx2lua & Unicode was Re: [wxlua-users] Problem in using Turkish
in wxLua scripts"

I think we have two competing needs, unicode for international
languages and UTF8 for ??? Can the two be mixed? I dunno.

[wxlua-users] Embeding a binary file into an executable

[Ryan P. <rpu...@gm...>]

Does anybody know how to embed a binary file into an executable and then
extract it back out at runtime. I want to create a utility that can make
application self contained and if they require dlls or external files they
can be packed into the .exe file. Then at run-time it extracts them and then
the main application can run and use the files.

I just found this as well. The icon I was trying to load from file had
multiple icons and sizes in it and it didn't like that either.

Well thanks I found it was the size of my xmp. I made it 32x32 and BAM it
worked.

I am really enjoying my wxLua experiance. It is fun to write a little script

I've noticed that it doesn't change too, under MSW, but couldn't
understand why, since it works in GTK.

Ahhh, I just discovered that you need to use a 32x32 bit XPM file or
load a 32x32 ico from disk in MSW.

If you want to change the icon that is displayed in windows explorer
you have to change the icon in the wxluafreeze.rc resource file and
recompile. I found these programs that I think should be able to
change the icon of a precompiled executable, but I haven't tested
either.

This was close, but I still can't get the frame icon to change. I can use
the bitmap created by the code above in a wxBitmapButton, but nothing
happens to the frame icon. I also tried to wxLua smaples that set the frames
icon and they didn't work either. The samples are wxluasudoku.wx.lua and
calculator.wx.lua.

[wxlua-users] Unicode Problem and the Copyright symbol ((c))

[Ryan P. <rpu...@gm...>]

When I wxluafreeze a script that has a Copyright symbol (c), the application
quits right away with no error or anything. I am using it in an about box
and I am just wondering if it has to do with Unicode at all. I am using the
prebuilt wxluafreeze from the 'bin' directory and I have built it myself as
well. I get the same result. Also, it works great when ran with "wxLua" and
not frozen. For now I am just changing the (c) to (c).

Any thoughts would be greatly appreciated.

Are you building on a 64 bit machine?

The wxFileModificationTime function has been rewritten to return a
wxDateTime instead of time_t since lua only has the double number type
so a wxDateTime is used to encapsulate it.

In wxWidgets 2.8 include/wx/filefn.h we have this

WXDLLIMPEXP_BASE time_t wxFileModificationTime(const wxString& filename);

and in wxLua/modules/wxbind/src/file.cpp

returns = new wxDateTime(wxFileModificationTime(filename));

finally, in include/wx/datetime.h we have

inline wxDateTime(time_t timet);

I don't understand why it doesn't work, wxFileModificationTime returns
time_t and wxDateTime takes time_t so why should it fail? I guess the
real problem is that wxFileModificationTime is missing for you.

==============================

Could you try to edit wxLua/modules/wxbind/src/file.cpp and test this
replacement code or variations of it to force your compiler to
recognize wxFileModificationTime? Maybe even try the wxWidgets minimal
sample and see if wxFileModificationTime works for you there?

returns = new wxDateTime((time_t)wxFileModificationTime(filename));

See above, but there is no reason why wxLua shouldn't be able to have
this work. It's something to do with your compiler or it's settings.

wxString is not used in wxLua. Someone had asked that it be added for
some special purpose so you can create it and get the string back from
it, but lua strings are used exclusively. This means that any
functions that takes or returns a wxString uses a lua string. You can
use the lua string.XXX functions to get most of what wxString offers
and it should work faster since it doesn't have to convert it in the
case where you've build wxWidgets for unicode.

I actually have tried release multilib and release monolithic. It actually
looks like the return type of '__int64' is the problem. Does that need to be
converted to something Lua specific? I am totally guessing and don't quite
understand the ins and outs of the internals of wxLua.

Humm, that is strange. I just tried in VC 2005 with the default
include/wx/msw/setup0.h in debug multilib without a problem. The
changes you made should probably not matter. I have updated the

I think, Cairo has more than I need. Most of my drawings are rectangles.
But I need some filled-arc drawing. Path and Stroke abilities seems
interesting. I need to learn them. Otherwise wxDC is enough for me too.

I'm collecting every OO solution mentioned in lua list. Yes, I believe
it could be possible to "shrink" my code with them.

I have to re-design graphics part anyway, but this time
I need to consider lua binding.

Maybe we can create a template solution for GUI design?
Lua already has more power than XML.

I already tested this part of wxLua. I generated binding for
wxSQLite3 by genwxbind. But didn't use it in the program. It
uses exceptions. I need to test it before use.

But you're right, it is very easy to generate binding.

My thinkings exactly! I'm very excited about development speed.

Thank you very much for sharing your thoughts and time!

No, for speed it is still best to use plain old wxDC stuff i think, but 
one day i will use it in wxArt2d,

Looking at the screen captures on your website I think wxLua could
handle all of that. Klaas is probably right that 80000 lines in lua
might be a little much. You'd have to be very structured and probably
implement some type checking using lua's assert. You'd miss out on the
compile-time checks which can catch a lot of bugs though. You might
want to try out one of the OO libraries for lua. On the other hand, if
your 80000 lines are in C, the hashtables and garbage collection lua
would get rid of all of the memory management code and some of the
nice little "tricks" you can use in lua with the tables make for very
tight and readable code.

I think that wxLua would be good for managing all of the structures it
looks like you use.  You'd probably want to use a dialog designer
program for much of the GUI, XML should work. You might want to create
a C++ module for the graphics if you're worried about the speed. You
can use your own custom wxEvent class to send notifications to wxLua
for major events while the C++ code does all the processor intensive
mouse moving logic.

It's incredibly easy to wrap C++ into wxLua using your own headers.
Just take the C++ headers, clean them up and turn them into a *.i
interface file(s), copy and edit one of the *_rules.lua files and run
genwxbind.lua on it. Once you have the C++ files, just add them to
your project and make sure you call the *_init function to install
them at startup.

The biggest plus for wxLua is that there's no compile time. The main
headache I have with C++ wxWidgets is that if you run into little
problems with sizing or things that need tweaks or misunderstood
flags, having to recompile for each test is a huge time sink.

-----

It might be good to feel things out in wxLua, start small with broad
strokes and tackle the bits that seem like they might be cause the
most trouble. Since lua translates into C fairly easily (except for
the tables), if things don't work in wxLua (please tell us why) and
you move to C++ you can reuse much of the code.
