wxlua-users Mailing List for wxLua (Page 5)

Hi Philipp ,

> luaL_register(L, wx2lua(m_nameSpace), wxlualib);
You probably also need -DLUA_COMPAT_MODULE, as luaL_register is not
part of Lua 5.2 if the compatibility mode is not turned on.
Paul.

Hi there,
I try to compile wxlua with the following options:
 cmake .. -DCMAKE_INSTALL_PREFIX=/usr \
 -DCMAKE_BUILD_TYPE=Release \
 -DwxWidgets_CONFIG_EXECUTABLE=/usr/bin/wx-config \
 -DwxLua_LUA_INCLUDE_DIR=/usr/include \
 -DwxLua_LUA_LIBRARY=/usr/lib/liblua.so.5.2 \
 -DwxLua_LUA_LIBRARY_USE_BUILTIN=0 \
 -DwxLua_LUA_LIBRARY_VERSION=5.2 \
 -DBUILD_SHARED_LIBS=TRUE
I hope that someone can help me fix this.
Regards,
Philipp

Yes this works because we have
lua_str="195円160円" UTF8 code for à 
but I would like to open a plain ASCii file in which à is coded as 0xE0 in my locale
and then
wx_str = wx.wxString(lua_str, wxFONTENCODING_ISO8859_1) (or something similar)
to get it converted to UNICODE

 Ahh, ok. Below is a list of the UTF8 chars to use.

 I ran this in wxLuaEdit and both wxMessageBoxes showed the char à I copied and pasted from the site above.

 wx_str = wx.wxString(lua_str)

Cross-platform compiling for different OSes from a single OS is not for the
faint of heart as it is usually very complicated. I'm also pretty sure that
the Apple provided clang compiler will not cross-compile to MSW or Linux.
The easiest way is to simply get a machine for each OS, dual-boot them, or
use virtual machines.
Note that Apple used to provide GCC as their XCode compiler, but they
switched to clang recently and I have not used it.

You need to have wxLua, Lua, and wxWidgets binaries built for each platform
you want to run on as they are the code that's actually interacting with
the OS. The Lua script code for wxLua simply calls the compiled binary
wxWidgets functions that eventually call the system provided functions to
create windows, menus, etc. Same for the 'os' Lua module and its functions
os.clock() for example.
Note that android and ios are experiment in wxWidgets and there is no
provision for them in wxLua.

You're not alone, it looks like the current trunk SVN has a fix for it if I
understand the last comment correctly.

wxWidgets has recently changed so that the >= 2.9 version always uses utf8
in the wxString.
There's a list of what it accepts in the section "wxString
<http://docs.wxwidgets.org/3.0/classwx_string.html> can be created from".

What do you plan to do with this wxString? You won't be able to display it
in the GUI since the high ASCII chars usually just show up as boxes not as
the DOS smiley faces and whatnot. I recommend sanitizing the string for
display by replacing the extended ascii and controls chars with '?' for
example.
You can make an ANSI build of wxWidgets (frowned upon in wx versions >=
2.9) and see if that does what you want...

It probably didn't exist in previous versions of wxWidgets. Added in SVN
now.

CMake prepends 'lib' to the name by default and I see that for the Mingw
build I do remove it. I'm not sure why I didn't do the same for Linux. I
think the right thing to do would be to actually name the 'wx.so' lib with
the Lua and wxWidgets versions and then symlink wx.so to it as most other
libs do.

In order to use Lua's 'require' you need to have the lua exe linked to a
shared lua.so and the lib you want to 'require' also linked to the same
lua.so. If you will 'require' other Lua C libs then these will also need to
be built and linked against the same lua.so library. This is why the lua.so
lib is not rolled into the wx.so lib and the lua exe linked only to wx.so.
In terms of where to put the lua.so lib, you can put it anywhere. Use
LD_LIBRARY_PATH or the program chrpath to change the rpath of the lua exe
to find it.
Hope this helps,
 John

Hi Jonh and Paul,
From8BitData() is static and To8BitData() mentioned in
(http://sourceforge.net/p/wxlua/mailman/message/32175781/)
but allowing to specify codepage (wxConvISO8859_1 or whatever) would be 
enought

This is lua2wx, it seems that it takes utf8 strings instead or ANSI with 
local codepage
WXLUA_USE_WXSTR_CONVCURRENT 1 should be tried?
------------------------------------------------------------
#define WXLUA_USE_WXSTR_CONVUTF8 1
#define WXLUA_USE_WXSTR_CONVCURRENT 0
// Convert a 8-bit ANSI C Lua String into a wxString
inline WXDLLIMPEXP_WXLUA wxString lua2wx(const char* luastr)
{
 if (luastr == NULL) return wxEmptyString; // check for NULL
#if WXLUA_USE_WXSTR_CONVUTF8
 return wxString(luastr, wxConvUTF8);
#elif WXLUA_USE_WXSTR_CONVCURRENT
 return wxString(luastr, *wxConvCurrent);
#else //!WXLUA_USE_WXSTR_CONVCURRENT
 #if wxUSE_UNICODE
 wxString str(luastr, wxConvUTF8);
 #else
 wxString str(wxConvUTF8.cMB2WC(luastr), *wxConvCurrent);
 #endif // wxUSE_UNICODE
 if (str.IsEmpty())
 str = wxConvertMB2WX(luastr); // old way that mostly works
 return str;
#endif //WXLUA_USE_WXSTR_CONVCURRENT
}
--------------------------------------------------------------
As an example compare wxLua with iconv:
It seems wxLua dont take ANSI but UTF-8
--------------------------------------------------
local iconv = require("iconv")
oldprint = print
require"wx"
print=oldprint
local str = ""
for i=0,255 do
 str = str .. string.char(i)
end
local cd = iconv.new("utf-8" .. "//TRANSLIT", "iso-8859-1")--IGNORE
--local cd = iconv.new("iso-8859-1" .. "//TRANSLIT", "utf-8")
assert(cd, "Failed to create a converter object.")
function showerr(err)
 if err == iconv.ERROR_INCOMPLETE then
 print("ERROR: Incomplete input.")
 elseif err == iconv.ERROR_INVALID then
 print("ERROR: Invalid input.")
 elseif err == iconv.ERROR_NO_MEMORY then
 print("ERROR: Failed to allocate memory.")
 elseif err == iconv.ERROR_UNKNOWN then
 print("ERROR: There was an unknown error.")
 end
end
for i=1,#str do
 local char = tostring(str:byte(i))
 --ANSI to UTF8
 local conv ,err= cd:iconv(str:sub(i,i))
 showerr(err)
 print(str:byte(i) , conv:byte(1,#conv))
 --ANSI to UTF8 in wx
 local convwx = wx.wxString(str:sub(i,i)):GetData()
 print(str:byte(i) , convwx:byte(1,#convwx))
 --UTF8 to UTF8 in wx
 local convwx2 = wx.wxString(conv):GetData()
 print(str:byte(i) , convwx2:byte(1,#convwx2))
end

Where I say UNICODE it should be whatever internal widebyte encoding the 
system and wxWidgets is using
as noted in
http://www.joelonsoftware.com/articles/Unicode.html
the problem is converting from ANSI to UNICODE
wxLua unicode build converts as if the string were UTF8 to UNICODE: return 
wxString(luastr, wxConvUTF8);
it works from code 1 to 127 (ASCii) but fails on 128-255 which are not valid 
UTF
0 is discarded in lua2wx :if (luastr == NULL) return wxEmptyString; // check 
for NULL
which is a problem for lua strings with embeded ceros
using AddTextRaw uses the string as an already UNICODE string so 1-255 are 
visible althought 128-255 dont show ANSI caracters
So would be ideal to having a function for converting from ANSI to UTF or 
UTF to ANSI (it depends on the ANSI codepage)
as in http://docs.wxwidgets.org/trunk/overview_mbconv.html example 1
(or may be ANSI to UNICODE and UNICODE to ANSI) 

actually wxMBConv and derived should be implemented because "Lua uses ANSI 8-bit strings" as says the wxLua manual but you can get in them every kind of data : unicode strings or embeded zeros.
So instead of needing require"iconv", wxLua would be enought

Hi John,
I'm still in need of having MacNewFile, MacOpenFiles, and MacReopenApp
methods (http://docs.wxwidgets.org/trunk/classwx_app.html) and would
appreciate any update on when you may have chance to add them.
If you don't have time at all to work on these and other methods, could you
give me a hint on how these can be added or maybe implement one of them and
I'll take care of the others? I can add existing methods (like those needed
for wxSTC or wxTreeCtrl), but it seems like these methods need some sort of
callback and I don't know how to provide that.
Paul.

Hi John,
Could you enable RegisterHotKey and UnregisterHotKey method in wxwindow?
Your comment says "only under WinCE", but it's not correct, as it's
available in Windows and should also be available on OSX with this fix:
http://trac.wxwidgets.org/ticket/12354. Thank you.
Paul.

Hi.
I installed Debian on a tiny pc. Caused by the fact jessie has packages for 
lua, luajit, rockspec and so on, installing a lua environment is a easy and 
quick task. wxWidgets-3.0.2 are available too.
Unzipping wxlua, running cmake and compiling wxlua is easy too. (I wish it 
would be so easy on windows too.)
Anyway there are 2 questions remaining:
- The resulting lua module is named liblua.so instead wx.so. What is the idea 
behind? I renamed libwx.so to wx.so to allow standard cpath to work.
- make generates libwx.so + libwxlua_lua51-wx30gtk2u-2.8.12.3.so
Why is there this libwxlua_lua51-wx30gtk2u-2.8.12.3.so? Is it possible to 
compile libwxlua_lua51-wx30gtk2u-2.8.12.3.so into (lib)wx.so? If not, where is 
a good place to store libwxlua_lua51-wx30gtk2u-2.8.12.3.so? 
TIA
