Re: [wxlua-users] stedit lib location

[klaas.holwerda <ng...@kl...>]

Hi,


For wxstedit the  wxWidgets_DEBUGFLAG is empty even if wxWidgets_USE_DEBUG is ON.
So it always comes out as: wxstedit-wx29gtk2u-1.6.0
But maybe that is wanted??
At least in wxWidgets 2.9.3 library names always come out without the "d", independent of debug or not version.
I myself stick to the old way for wxart2d, but i think in general on Linux indeed library name stays the same, independent of debug or not info.

It would still be nice to have the same naming scheme in wxLua.
Using something like this I think, WXLIKE_LIBRARY_NAMES( wxStEditLib wxstedit "${wxStEdit_VERSION}")
This name is handy to have.

I do use wxLua and wxStedit after installing them (why no headers?).
But for wxstedit, something is taken from here, where I compiled it:
wxStEdit_ROOT_DIR = /home /klaas/soft/usr/local/soft/wxstedit

But my install prefix is this:

BUILD_INSTALL_PREFIX = /home/klaas/soft/usr/local

This line was needed to make it find the right headers of some things in lua, which I can not install in "/usr/local".
INCLUDE_DIRECTORIES( "/home /klaas/soft/usr/local/include" )

/home/klaas/soft/wxLua/modules/lua/src/luaconf.h:275:31: error: readline/readline.h: No such file or directory

Do not know how this should be fixed using prefix something??

Next is worse, I can not use media in wxwidgets, so the next I do not have: libwx_gtk2u_media-2.9.a
How can I easily/normally disable this for wxLua?

make[2]: *** No rule to make target `/thales/thales_localdata/db348/soft/usr/local/lib/libwx_gtk2u_media-2.9.a', needed by `modules/wxlua/libwxLuaLib.so'.  Stop.

Removed media in the next two lines:

set(wxWidgets_COMPONENTS xrc xml net media propgrid richtext aui stc html adv core base) # minimal set for static lib/dll
set(wxLuaBind_ALL_COMPONENTS gl stc xrc richtext html media aui adv core xml net base )

Also I was fooled by old stedit headers in /usr/local/include/wx/stdedit, they are not installed by wxstedit "make install"
Maybe install them relative to here??

/usr/local/include/wx-2.9

I use things like:

/usr/local/include/wxart2d-1.2/

Same for wxLua, also headers are not installed.
Now I understand that I need to find it from the place where it is compiled.
And I do require the user to set the path/vars WXLUA and WXSTEDIT  to find it.
I still wonder what is the right approach??
Normally I just need to install libraries and devel versions of it on Linux, in order to use them with headers.
That is how wxWidgets deals with it also.
For wxStedit, that looks oke to do.
But for wxLua, something extra would be need to find the bindings. ( I would say/usr/local/share/wxlua/  )
I do this, which is I think CMake like. Maybe it would be oke for wxLua also.

10:05:45 509>  pwd
/ usr/local/share/wxart2d
10:03:31 507>  ls -R
.:
  FindwxArt2D.cmake  luawraps  UsewxArt2D.cmake  wxArt2DConfig.cmake  wxart2dMacros.cmake

./luawraps:
src

./luawraps/src:
wxart2d_datatypes.lua


At last:

I had to add #include "wx/progdlg.h" here:

#if wxUSE_PROGRESSDLG&&  wxLUA_USE_wxProgressDialog
     #include "wx/progdlg.h"
     #include "wx/generic/progdlgg.h"
#endif // wxUSE_PROGRESSDLG&&  wxLUA_USE_wxProgressDialog


And I need to compile wxWidgest with -fPIC again (something to do with shared libraries in lua, see mailinglist archive):

make CXXFLAGS=-fPIC CFLAGS=-fPIC

Hope it helps.
Somehow it feels easier than the first time, also on windows.

Thanks,

Klaas

It should compile without a problem in Centos as I use RHEL6 regularly
without any problems. I just built it yesterday. Can you please post

This sounds good. I currently use a higher level CMakeLists.txt that
includes the wxLua and some other projects' CMakeLists.txt to have the
binaries put in the same place for convenience so I never see what
happens by default.

set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${CMAKE_CURRENT_BINARY_DIR}/bin)

Use a unique wxWindow ID or wxWindow::Get/SetName() to give each
notebook page a unique name so you can find the window no matter what.
You can also use wxWindow::FindWindowById/Name(). Doing this should be
the cleanest solution since you will definitely know what window
you're getting.

Here's how to get information about what an object is and how to cast
wxObject derived classes up and down their class hierarchy.

The wxClassInfo is may not be right for all classes and this function
only works for wxObject derived classes, but it will work for all
major classes. You can also just call Lua's tostring() function to get
the object type as string name. NOTE! The integer number is NOT fixed
between versions, but will be constant within a single run.

Here's some code run in the wxLuaEdit console to show some of the
possibilities and what works and what doesn't.

f = wx.wxFrame(wx.NULL, -1, "Hello")
w = wx.wxWindow(f, -1)
f:Show(true)
c = wx.wxComboBox(w, -1)
ci = c:GetClassInfo() -- from wxObject
print(ci)
userdata: 0x161d918 [wxClassInfo(0x7f33d2cf8b40, 23)]
print(ci:GetClassName())
wxComboBox
print(tostring(c))
userdata: 0x161b368 [wxComboBox(0x1614c00, 134)]
cw = c:DynamicCast("wxWindow")
print(cw)
userdata: 0x16273f8 [wxWindow(0x1614c00, 368)]
ciw = ci:DynamicCast("wxWindow")

[wxlua-users] stedit lib location

[klaas.holwerda <ng...@kl...>]

Hi John,

Busy making wxLua compile on Centos 64but, in general same issues as found with Ubuntu.

For wxstedit using Cmake, i think you should add this line in its CmakeLists file:

set (LIBRARY_OUTPUT_PATH ${wxStEdit_BINARY_DIR}/lib )

This makes in generate the library in there on windows using Debug/Release as subdir, on Unix in there directly.
Currently it is placed directly in the top dir, while "make install" expects it in the lib directory, which i think is the right one.

Klaas

I just tried it in MSW with Unicode and ANSI builds, running the wxLua
editor the Sanskrit characters show up fine in the Unicode build and
as ??? in the ANSI build.

So I will have to provide Unicode binaries then.

I don't have access to a Linux machine, but tried on MacOS (with the

got question marks and some special characters. On Windows I just get

I think mine are from the official wxlua site, so are probably
compiled in ANSI mode.

Where did you get your binaries? The Windows 2.8.10 ones at
wxlua.sf.net are compiled in ANSI and not Unicode. The idea was that
since Lua is ANSI wxLua might as well be too since multibyte chars
will not be handled properly in the Lua string.XXX functions. However,
if you are careful it can be made to work.

You have to recompile wxLua for Unicode, linking against a Unicode
wxWidgets build. When compiled in ANSI mode, strings are considered
one char per byte and that's it.

I plan on providing binaries for Windows compiled in Unicode for the
next release.

Yes, the function returned "const wxDateTime& GetDate() const" which
is an optimization for when you want to simply call a wxDateTime
function and not save the object itself.

I've changed it so that it simply returns a new wxDateTime object so
it will never go out of scope when the event is garbage collected.
I've also added a wxDateTime copy constructor so that you can make
copies of a wxDateTime using:

dt1 = wx.wxDateTime(...)
dt2 = wx.wxDateTime(dt1)

This should fix any problems with the wxDateEvent.

[wxlua-users] wxLua and UTF8 encoding on Windows

[Paul K <pau...@ya...>]

Hi All,

I've been working on a wxLua-based IDE
(https://github.com/pkulchenko/ZeroBraneStudio/) and have a bug opened
about dealing with utf-8 encoding
(https://github.com/pkulchenko/ZeroBraneStudio/issues/7). I've
captured relevant information in the ticket; to summarize, I seem to
be setting correctly both the the codepage
(SetCodePage(wxstc.wxSTC_CP_UTF8)) and the encoding
(wxFONTENCODING_UNICODE), but the text is still shown as single-byte
garbled content (there are some examples in the ticket), even though
the editor seems to recognize that these are two-byte characters (as
it doesn't allow to position the cursor in the middle of any unicode
character).

Also, when I set wxFONTENCODING_UTF8, I get "No font for displaying
text in encoding 'Unicode 8 bit (UTF-8)' found." and even after I
select "Lucida Sans Unicode", which is reported to be a unicode font,
I still have the issue above.

I also found this message from John "They probably compiled it in ANSI
mode and not Unicode. Note however
that Lua is strictly ANSI only." in this thread
(http://comments.gmane.org/gmane.comp.lib.wxwidgets.wxlua.user/2636).
Does this mean that the binaries I'm using need to be compiled with
some other configuration (Unicode mode)? Note that in my case I'm not
manipulating UTF strings, I just want them to be displayed correctly
in the editor.

Selecting File | Encoding | UTF-8 in Scite from Lua4Windows displays
the same text correctly, which confirms that this is not a font issue.

What am I doing wrong here? Is there *any* WxLua based application
working on windows with UTF8 encoded text (with or without BOM)? I've
tested with both 2.8.7 and 2.8.10 (on windows Vista) with the same
result. WxLua and wxLuaEdit also show the same behavior.

Paul.

problem is that event:GetDate() is not cal:GetDate() 
but a temporary wxDateTime() the code should probably be 

dt = wx.wxDateTime(event:GetDate().JDN)

but Houston we have a problem

event:GetDate():GetJDN() returns a double
and wx.wxDateTime expect an unsigned integer

the best solution I could find is
        local tdt = event:GetDate()
-- must init with a valid time (a valid JDN would work like 2456100)
        dt = wx.wxDateTime(os.time())
        dt:SetYear(tdt:GetYear())  -- copy time from temporary
        dt:SetMonth(tdt:GetMonth())
        dt:SetDay(tdt:GetDay())
        dt:SetHour(tdt:GetHour())
        dt:SetMinute(tdt:GetMinute())
        dt:SetMillisecond(tdt:GetMillisecond())

I am sure there is a better way.

This is probably not right, you would need to call it like this.

it = aa:const_iterator()
print(date:ParseDate(aa, it))

They're required for using UTF8 since not every code point is a single char.

I think the simplest solution is to return two values, [bool, Lua
String of start of input on failure] where the second Lua String is
only returned on failure and contains the start of the input string up
until the failure. I hope to have time to do it tomorrow night.

I am having a hard time understanding the use of iterator in wxlua.

I guess an iterator is created by wxString::const_iterator end() or 
wxString::const_iterator begin() for wxString which would be coded 
wx.wxString(str):end() but end is a reserve word in Lua. I guess end could be 
renamed.

the code would be
date:ParseDate(aa,  wx.wxString_const_iterator(aa:end()) )
since aa:end()returns a wxString_iterator

Note: that using begin() give unexpected results

aa = wx.wxString("09-06-2012")
print(date:ParseDate(aa, wx.wxString_const_iterator(aa:begin())))
aa = wx.wxString("")
print(date:ParseDate(aa, wx.wxString_const_iterator(aa:begin())))

display:
true
false

I would have expected both of these to be identical.

--------------------------------------------------------

Are iterators useful in wxLua? The addition in wxWidget maybe justified for 
saving copying of strings in a tight loop but most of the time C++ programmer 
will replace their code in the following way and live with the overhead.

old code: foo(v) 
new code: foo(v,&(type::const_iterator)v.end) // would not compile purely for 
illustration.

In wxLua using foo(v) or foo(string.match(v,pattern)) seems so much simpler than 
using an iterator.

ParseDate is not the only function using iterator but all of them seem similar.

Thank you.

wxLua uses the wxWindows/wxWidgets license which is LGPL with an
exception for binary linking and distribution on your terms. You do
not need to do anything special and I still recommend using  wxApp to
initialize the event loop.

I agree that the current functions are awkward to use. I will make the

Do you have some code that demonstrates this? I can't think of any

[wxlua-users] wxCalendarCtrl

[Блажнов В. <vbl...@ya...>]

Got the strange difference between event:GetDate() and calendar:GetDate() in wxCalendarCtrl event handler. If I use dt = calendar:GetDate() directly (ignoring event argument) for saving wxDateTime value then I have correct value after dialog destruction. But if I use dt = event:GetDate() then dt value becomes broken after dialog destruction. 

[wxlua-users] Back to ParseDate

[Andre A. <ar...@ki...>]

using date:ParseDate(value, wx.wxString_const_iterator()) 

seems to work but looking into the run time we see that the pointer to the 
iterator is a bad pointer not very desirable.

supporting a single argument seems preferable.
The following code works.

static int LUACALL wxLua_wxDateTime_ParseDate(lua_State *L)
{
    // wxString date
    wxString date = wxlua_getwxStringtype(L, 2);
    // wxString::const_iterator end
    wxString::const_iterator * end;
	if (lua_type(L, 3) == LUA_TNONE)
		// missing argument
		end = &(wxString::const_iterator)date.end();
	else
		end = (wxString::const_iterator *)wxluaT_getuserdatatype(L, 3, 
wxluatype_wxString_const_iterator);

but a similar change would be needed for each function expecting an optional 
iterator.

currently wxlua_getwxStringtype does not seem to handle a missing argument.
If it returned NULL we could trigger on the result.

maybe a special function 
   end = GetOptionalIterator(L, 3, date);
which returns the_iterator || &date.end() could be used.
