I'm guessing that you are on MS Windows?

That is surprising and not normal unless you have run some installer
(perhaps the Lua 5.1 you speak of) that changed the default
application to "open" *.lua files. wxLua does not change any file
associations, registry entries, and takes the position of causing the
least harm to people machines.

It sounds like you are using someone else's lua.exe to require("wx"),
meaning that the wx.dll will be loaded by lua.exe to provide the wxLua
functionality. In order for this to work, without error, the lua.exe
and wx.dll MUST be compiled using the SAME version and Lua 5.1
compilation settings. This requirement is nothing special to wxLua,
but applies to dlls in general, they must all be "binary" compatible
with each other. Note that slight mismatches between exes and dlls can
lead to arbitrary crashes and this is why I do not recommend it.

I DO recommend running the wxLua samples using the lua.exe that is
provided by the wxLua binary packages since it is definitely binary
compatible with wx.dll.

Welcome to wxLua, I hope you enjoy it,

[wxlua-users] wxlua docs up-to-date? (Windows)

[Mike P. <mik...@li...>]

Hi - I'm new to Lua and wx as well.
I downloaded Lua 5.1, and was reading the wxlua manual 2.8.

Section 6.1 - How to run the samples.

I use Windows, and found the instructions rather complicated (what is the $ - I
guess it is the Unix prompt).
Anyway, I simply double-clicked on the sample files to run them!

So, I wondered if the manual is not up-to-date with the file associations set up
by the latest Lua.
Best Wishes
Mike

Yes, everything in wxWidgets/lib/gcc_lib should be static wxWidgets libs.

I use the CMake provided FindwxWidgets.cmake that prefers gcc_dll only
when BUILD_SHARED_LIBS is TRUE. It does seem like it needs to be run
twice. If you run the cmake-gui new variables are marked in red and
the install.html instructs people to re-configure until all the red is
gone. From the command line it is not so clear to the user. I will
make a note in the install.html that people should run cmake from the
command line at least twice.

To be sure, everything builds and works? (except for having to run
cmake twice which is probably unavoidable)

I meant that wx.dll depends on WXBASE294U_NET_GCC_CUSTOM.DLL for example, 
althought in the command line I asked for BUILD_SHARED_LIBS=FALSE  and 
pointed to gcc_lib.
When I run first time I get BUILD_SHARED_LIBS=FALSE but libraries point to 
gcc_dll.
When I rerun command line without deleting previous results I get 
BUILD_SHARED_LIBS=FALSE and libraries correctly pointing to gcc_lib.
So running command line twice seems to solve the problem for me, but it is 
confusing and I dont know if it is intended to be that way.

The wxWidgets exec sample uses a wxTimer to poll the stream for data.
You just have to connect to wxEVT_END_PROCESS and turn off the timer
when it exits or kill it like you do if it doesn't respond in a timely
fashion.

See, MyFrame::OnExecWithRedirect() and MyFrame::AddPipedProcess()
http://svn.wxwidgets.org/viewvc/wx/wxWidgets/trunk/samples/exec/exec.cpp?view=markup

Regards,
    John

ps. My previous comment was to confirm that you have seen the docs and
are doing all the checks. My experience with processes is that they
can be finicky if things aren't just right. In fact, you should always
connect to wxEVT_END_PROCESS in case the user or OS kills your process
for you...

Re: [wxlua-users] Can't read output with wxPROCESS_REDIRECT and wxEXEC_ASYNC

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

Hi João,

Thanks again for your example, as I ended up with something that was
closer to yours than to my original plan (as mine was blocking the app
if the other application wasn't printing anything). For those who are
following the thread, this is what I ended up with:

        local proc = wx.wxProcess()
        proc:Redirect()
        proc:Connect(wx.wxEVT_END_PROCESS, function(event) proc = nil end)
        local bid = wx.wxExecute(cmd, wx.wxEXEC_ASYNC +
wx.wxEXEC_MAKE_GROUP_LEADER, proc)
        if not bid or bid == -1 or bid == 0 then
          DisplayOutput(("Program unable to run as '%s'\n"):format(cmd))
          return
        end

        local streamin = proc:GetInputStream()
        for _ = 1, 10 do
          if streamin:CanRead() then
            -- do something with streamin:Read(4096)
          end
          wx.wxSafeYield()
          wx.wxWakeUpIdle()
          wx.wxMilliSleep(250)
        end

        -- kill process if couldn't read after 10 attempts
        -- wx.wxProcess.Kill(bid, wx.wxSIGKILL, wx.wxKILL_CHILDREN)

If this is about some confusion about what wxWidgets libs you are
linking to, you can see the list of them printed out when cmake is
run.

[wxlua-users] Build fixed for MingW

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

Hello,

I have gone through and fixed and cleaned up the MingW build. It works
in both 2.8 and 2.9 now.

The proxydll also works. This means that you can run the static
lua.exe from the build/bin/[Debug/Release...] dir and using the
lua51.dll proxydll (11kB) call "wx = require("wx")". Note that you can
make a copy of the proxy lua51.dll and rename it to satisfy a
precompiled Lua51 3rd-party library's need for a lua51.dll by another
name.

More complete

-2.8.12 with wxLuaFreeze.exe I see right arrow
-2.8.12 with lua.exe I see left arrow

-2.9.4 with wxLuaFreeze.exe I see right arrow
-2.9.4 with lua.exe crash

So it seems that the correct resource is never loaded using lua.exe but it 
crash in wxWidgets 2.9.4 because it asserts.

I saw the resources from wx.dll compiled by you and the mingw compiled by 
me: Resouce numbers from cursors are different 1 to 11 in mingw but  4 to 14 
in your compilation

Is there any particular problem with the logic I described? I know how
to use streams (I use it in other parts of the application), but I
wanted to have something very simple here (and ideally synchronous). I
oversimplified the logic (there is also CanRead() and few other
things), but the idea is as I described. I do check if the returned
value is not nil. Is there anything else you suggest I need to do?
Thanks.

Please read the description of wxProcess where they describe how to

This is a wx.dll initialization problem (the resources are declared in
wxWidgets/include/wx/wx.rc file) and there is nothing significant
between the 2.8.12 resources and 2.9.x resources. I really don't
understand this problem and I'm thinking that it's a Mingw problem.

To be sure:

You use mingw?
This problem occurs in 2.9.4 running "lua editor.wx.lua", but not with
"wxluafreeze editor.wx.lua"?
Does this problem occur with 2.8.12 in mingw? (the wxlua-2.8.12.zip is
built using Visual Studio)

Depending on your answers we can narrow it down to a 2.8.12/2.9.4 or a
Visual Studio/MingW problem.

Re: [wxlua-users] Can't read output with wxPROCESS_REDIRECT and wxEXEC_ASYNC

Hi João,

Thank you for the solution. I ended up using the following, as it
allows me to implemented synchronous processing (while still using
EXEC_ASYNC):

        local proc = wx.wxProcess.Open(cmd) -- this is using EXEC_ASYNC
        proc:Redirect()
        local streamin = proc:GetInputStream()
        local str = streamin:Read(4096)

:Read() blocks waiting for input, which is exactly what I need.

Re: [wxlua-users] Can't read output with wxPROCESS_REDIRECT and wxEXEC_ASYNC

[João M. <lor...@gm...>]

Hi Paul,

Did you try this:

    proc = wx.wxProcess()

    proc:Connect(wx.wxEVT_END_PROCESS,
      function(event)
          print("Hello - the process is over and won't be deleted.")
          -- event:Skip(true) <-- will crash since wxWidgets will delete it
too
          -- proc = nil
          -- collectgarbage( "collect" ) -- not necessary, but it tests the
problem
      end
    )

    proc:Redirect()
    wx.wxExecute( cmd, wx.wxEXEC_ASYNC, proc )

I get this code somewhere and work fine for me.

[wxlua-users] Can't read output with wxPROCESS_REDIRECT and wxEXEC_ASYNC

Hi All,

I'm trying to read output from a program and am having trouble with
the following three lines of code:

      local pid = wx.wxExecute(cmd, wx.wxEXEC_ASYNC, proc)
      local streamin = proc:GetInputStream()

The app crashes on any attempt to get input stream. The following code
with EXEC_SYNC works fine though:

      local pid = wx.wxExecute(cmd, wx.wxEXEC_SYNC)

But this doesn't give me any way to access the output of the command I execute.

I suspect the problem is in the first parameter in wxProcess:
wx.wxProcess(wx.NULL, but I don't see any other way to not provide
wxEvtHandler or create a dummy one (replacing wx.NULL with
wx.wxEvtHandler() has the same effect: the app crashes).

This is all on windows 7 running fairly recent 2.8.12.2 code. I'd
appreciate any ideas on how to get program output. Thanks.

Paul.

Re: [wxlua-users] wxSTC in 2.9.4

[Victor B. <so...@te...>]

There was a mistake in post: I mean  running editor.wx.lua sample with 
wx.dll compiled against 2.9.4 wxWidgets
I have also tryed the stc sample of wxWidgets 2.9.4 but I dont get the same 
error. 

[wxlua-users] wxSTC in 2.9.4

[Victor B. <so...@te...>]

I am afraid that this post got lost because I was mixing threads. So I 
repost it in new thread:

Compiling wxLua with wxWidgets 2.9.4 but not with 2.8.12 I get an assertion 
when running wx.lua.sample and  mouse
is over  the left margin (markers and so on) of a wxstc.editor

assert "Assert failure" failed in InitFromStock(): Loading a cursor defined
by wxWidgets failed, did you include include/wx/msw/wx.rc file from your
resource file?
'LoadCursor' failed with error 0x00000714 (there was not resource section on
the image

after continuing the program

'LoadCursor' failed with error 0x00000000 (no error)

If not on debugger the program just crashes after assert.

Something like that, but quite a bit more work is involved to do it
the right way and have it reusable in similar functions.

Implemented now in SVN.

[wxlua-users] wx.wxGetTextFromUser

[Milind G. <mil...@gm...>]

Hi,
        I see that if I have my wxlua application running and put windows
on sleep. Then on waking up the computer the wx.wxGetTextFromUser dialog
box does not show up. It has been activated since my application won't
respond since the focus seems to be on that dialog which is somehow
invisible and if I type something and press enter it is as if the box
accepted the text and worked and returned control to the application.
        To make this work properly I have to exit the application and
restart it. This is happening in windows 7, I haven't tried it on other
platforms. Does anybody else see the same thing?

Thanks,
Milind

Re: [wxlua-users] Which wxWidgets?

[Victor B. <so...@te...>]

Still testing 2.9.4 against 2.8.12. I get very often this assertion with 
2.9.4 in the debuger:

assert "Assert failure" failed in InitFromStock(): Loading a cursor defined 
by wxWidgets failed, did you include include/wx/msw/wx.rc file from your 
resource file?
'LoadCursor' failed with error 0x00000714 (there was not resource section on 
the image

after continuing the program

'LoadCursor' failed with error 0x00000000 (no error)

I not on debugger the program just crashes after assert.

//////////////
I have tryed with editor.wx.lua sample and I get the same error when mouse 
is over  the left margin (markers and so on) of a wxstc.editor. So it seems 
it is not a lua lanes problem.
