Re: [wxlua-users] How to check type when iterating over wxWindowList

Hi John,

This looks like exactly the information I was looking for. DynamicCast
is the method I was missing. Thank you for the detailed examples.

Paul.

 I have the same problem as described here

 when tabs in AuiNotebook are moved using drag and drop, their order

 them in the right order.

 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.

 I can get the list of children for my notebook
 (notebook:GetChildren()) and can enumerate those using
 GetFirst()/GetNext() and then get their target using GetData(), but
 all their targets are of wxWindow type. How do I know which one is
 AuiTabCtrl and how do I cast it to AuiTabCtrl to call GetPage()?

 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)

 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] UPDATE_UI events not triggered for menu items in full-screen mode

2012-06-27 Thread Paul K

Hi John,

I think this is a bug in wxwidgets, but I'm looking for suggestions
about a workaround.

Essentially, if the application has menu items that change their
state, the change in that state is not detected when the application
is in full screen mode (and the menu is hidden). The same issue is
described here (http://forums.wxwidgets.org/viewtopic.php?f=1t=32224)
and this ticket may be related too
(http://trac.wxwidgets.org/ticket/4843).

I can see that UPDATE_UI event is triggered in a normal case when an
accelerator key is used (even when the menu is disabled), but it is
NOT triggered when the menu is hidden, which doesn't allow to fix
its state. I tried using

frame:UpdateWindowUI(wx.wxUPDATE_UI_RECURSE) and
frame:UpdateWindowUI(wx.wxUPDATE_UI_FROMIDLE)

but I don't see the UPDATE_UI triggered for that particular item. I
also tried your code from wxLua (btw, why did you use it in your
case?):

function UpdateUIMenuItems()
if frame and frame:GetMenuBar() then
for n = 0, frame:GetMenuBar():GetMenuCount()-1 do
frame:GetMenuBar():GetMenu(n):UpdateUI()
end
end
end

but it doesn't trigger UPDATE_UI either (in full screen mode). I tried
putting this code in KEY_DOWN and ON_IDLE events with the same result.

Is there a way to force UPDATE_UI on those menu items to make the
accelerator keys work? Is there another workaround?

This is on Win32 using wxwidgets 2.8.7. Thank you.

Paul.

Re: [wxlua-users] Preliminary wxLua Binaries for 2.8.12 for MSW

2012-06-29 Thread Paul K

Hi John,

Thank you for making the binaries available! I gave the Unicode
binaries a try, but the results are a mixed bag. I can barely get them
running for my application, which allows me to confirm that UTF-8
encoding is now working, but other encodings stopped working. For
example, if I set font encoding to wx.wxFONTENCODING_CP1251, I see no
difference (it looks like it's always fixed to utf-8). This may be a
feature though. If this is going to be the way it is, I'm fine with
it.

Also, I can't get the binaries to work correctly with my application.
The first issue is that the existing lua socket binaries fail to load:

...\bin\lua.EXE: error loading module 'socket.core' from file
'bin/clibs/socket\core.dll':
The specified module could not be found.

even though the module *is* there and loads fine using the old
binaries. This may be related to the fact that socket\core.dll seems
to be compiled against lua5.1.dll, which you didn't include in the
package (and my existing one didn't work as it's not for 5.1.5).

If I comment luasocket out, the app crashed somewhere in
wxlua_lua_shared-wx28mswu-2.8.12.dll:

This is running on Windows Vista (32bit). I only deployed wx.dll and
wxlua_lua_shared-wx28mswu-2.8.12.dll (not sure what
wxlua_lua_shared-wx28mswu-2.9.4.dll was for as wx.dll didn't want to
work without 2.8.12.dll). I thought I could pick what version of
wxwidgets I want to use (2.8.12 vs. 2.9.4), but it didn't work that
way.

I don't quite understand the difference between lua.exe and
lua_shared.exe. It seems like lua.exe doesn't need lua51.dll, but
lua_shared.exe runs without that dll also, as you don't seem to
include the dll.

Also,  wxLua* binaries (Freeze, Edit, etc.) seem to be statically
compiled and the previous version had them dynamically compiled (which
would be my preference, although other people may prefer it
differently).

Re: [wxlua-users] Preliminary wxLua Binaries for 2.8.12 for MSW

2012-06-29 Thread Paul K

Hi John,

Couple of other things. The new version seems to be using
significantly less memory. When I can get the app to start, it's only
using about 7.8M memory, where the old one was using 13-14M. This may
be related to the reduced size of the dlls.

Also, the error message box is gone and the app seems to be failing
silently where the old one was reporting errors in a nice dialog with
wxLua title and a message Lua: error while running chunk. This was
one of the primary reasons we stayed with the binaries we are
currently using and I'd love to have that error message back.

The error messages we used to be getting seem to be coming from
wxString wxlua_LUA_ERR_msg(int LUA_ERRx) function in wxlstate.cpp
with the value LUA_ERRRUN. I'm not sure why the new version doesn't
trigger/report that anymore.

Re: [wxlua-users] Preliminary wxLua Binaries for 2.8.12 for MSW

2012-06-29 Thread Paul K

Hi John,

One more update. I didn't mention how I got the app running, which is
the best configuration I can get so far. I deployed wx.dll and
wxlua_lua_shared-wx28mswu-2.8.12.dll as well as lua_shared.exe
(renamed as lua.exe) and kept my *current lua5.1.dll* file. This way I
could get the app started even though it still crashes in several
places (but at least the luasocket library is working).

I'm also getting strange errors where I had none before; for example,

Expected an 'unsigned integer' for parameter 1, but got a 'number'.
Function called: 'wxMilliSleep(number)'
01. wxMilliSleep(integer)

Is it possible that there is something wrong with the binding as
unsigned integer should be easily mappable to number?

Another strange error is this:

wxLua: Creating a callback function in a coroutine is not allowed
since it will only be called when the thread is either suspended or
dead.
stack traceback:
[C]: in function 'Connect'

This is probably in reference to this normally looking code (it's not
using any coroutines):

  frame:Connect(wx.wxEVT_CLOSE_WINDOW,
function(event)
  if inloop then event:Skip() frame = nil else os.exit() end
end)

In addition to that, I'm getting an appcrash when I close the app
(inside ntdll.dll), but this is likely because I'm using your lua.exe
with my dll from a previous version. For some reason using my current
lua.exe crashes the app with an error in
wxlua_lua_shared-wx28mswu-2.8.12.dll (which I reported earlier).

 Personally, I don't use update ui events as they are sent a little too
 often for my likes. I find that a single function that updates the gui
 state, menus, toolbars, buttons, etc.. works very well and is less cpu
 intensive. All you have to do is call it whenever there is a chance
 the state will change. This also has the benefit of getting all the
 update code in one place since the state of various items are often
 interrelated.

Re: [wxlua-users] Preliminary wxLua Binaries for 2.8.12 for MSW

2012-06-30 Thread Paul K

Hi John,

(combining responses from three different messages)

It all makes sense; I agree on UTF8.

 You can't always expect that a lib compiled with one version of code
 to work with another. Ideally you would build wxLua and the socket lib
 together to ensure they both are using the same Lua library. In this
 case they are trying to use different lua51.dlls which is a real
 problem, they have to both use the same one.

I understand. Any chance you can compile luasocket and luasec or at
least provide details on your build environment, so that I can match
it with my own compatible versions for those modules. I bet it's going
to be a problem for many people using new binaries (as binaries for
both of those modules will end up incompatible and many people will be
confused and disappointed).

 Someday it may be possible to relax the conditions, but only for
 certain hand-picked functions. However, the reality is that I don't
 have the time to write docs for each exception so it's best to stick
 to the wxWidgets documentation since it's free and it's right.

That's okay, I'll add an explicit conversion. I just wasn't sure what
has changed and if this should be addressed in my code.

 People complained about the error box. I plan to replace it with a
 text console (like wxLua -c) so that when running error message will
 stream to it. This will be something that in Lua you can enable or
 disable it, e.g. wxlua.ShowConsoleOnPrint(true/false) or something.

I think this would be an inferior solution comparing with the error
box. For me as a developer, it's critical to know when something is
not working. Right now, if I made a mistake, I get a detailed error
messages in my face. With a text console, I'll need to keep it on and
monitor all the time.

It's even worse for my users. If one of my bugs slips through and
something is not working (let's say I made a mistake in EVT_CLOSE
event handler), the window will fail to close without any visible
indication as to what's wrong (and also possibly leaving the app in
some inconsistent state without any indication either). And there is
nothing to report back to me. I can't ask my users to turn the console
on if something looks strange in their application.

 I don't understand this. The logic to trigger this error is very
 simple, when wxLua starts it saves a pointer to the lua_State* in the
 Lua registry. When an event callback is created the given lua_State*
 is compared with the original lua_State* in the registry and if they
 don't match you must be in a coroutine which means that Lua will give
 you an error about running code in a suspended or dead coroutine so
 instead of that rather cryptic message given later I error out
 earlier.

It's possible that it's from using two dlls, but I'll need to re-test this.

Essentially, even with the current binaries I should be able to remove
socket calls and add explicit type conversion and use it without any
issues. What I'm concerned about it the crash I was getting:

 If I comment luasocket out, the app crashed somewhere in
 wxlua_lua_shared-wx28mswu-2.8.12.dll:

 No message?

Right, no message, just a windows crash report. I'll re-test shortly
as I now understand better what the different DLLS are for, but I
don't expect this to change.

 I am working on using a proxydll along the lines of this :
 http://lua-users.org/wiki/LuaProxyDllFour

What do we gain by using LuaProxyDll? I thought I could do require
'wx' from a statically linked LuaFreeze even today?

 Hi John,

 Thank you for making the binaries available! I gave the Unicode
 binaries a try, but the results are a mixed bag. I can barely get them
 running for my application, which allows me to confirm that UTF-8
 encoding is now working, but other encodings stopped working. For
 example, if I set font encoding to wx.wxFONTENCODING_CP1251, I see no
 difference (it looks like it's always fixed to utf-8). This may be a
 feature though. If this is going to be the way it is, I'm fine with
 it.

 I have never needed to change the wxFONTENCODING so I don't think it
 is necessary. I bet you were trying to change it to map upper ASCII
 chars appropriately to a font, a poor mans Unicode that probably works
 well for Latin languages with tildes and such, but that's about it.
 When you use Unicode you don't need to mess with all that since UTF8,
 for example, can describe any character.

 Note the comment about  Please note that we will only discuss 8-bit
 fonts here and not Unicode (see Unicode Support in wxWidgets).
 http://docs.wxwidgets.org/trunk/overview_fontencoding.html

 Unfortunately you either work in Unicode or ANSI and hope that the
 upper ASCII chars map to the letters you need. I don't think you can
 ever have it both ways as the upper ASCII chars are not
 compatible/equivalent to Unicode chars in any format.

Hi John,

A bit more information on my testing without luasocket.

I removed all the existing DLLs and deployed your lua.exe, wx.lua and
wxlua_lua_shared-wx28mswu-2.8.12.dll.

When I start my app, it crashes immediately (without any error
message) with this report:

If I start a bit simpler version, it does show the editor window, but
when I close the app (without doing anything else), it crashes with
another crash report:

 Hi John,

 (combining responses from three different messages)

 It all makes sense; I agree on UTF8.

 You can't always expect that a lib compiled with one version of code
 to work with another. Ideally you would build wxLua and the socket lib
 together to ensure they both are using the same Lua library. In this
 case they are trying to use different lua51.dlls which is a real
 problem, they have to both use the same one.

 I understand. Any chance you can compile luasocket and luasec or at
 least provide details on your build environment, so that I can match
 it with my own compatible versions for those modules. I bet it's going
 to be a problem for many people using new binaries (as binaries for
 both of those modules will end up incompatible and many people will be
 confused and disappointed).

 Someday it may be possible to relax the conditions, but only for
 certain hand-picked functions. However, the reality is that I don't
 have the time to write docs for each exception so it's best to stick
 to the wxWidgets documentation since it's free and it's right.

 That's okay, I'll add an explicit conversion. I just wasn't sure what
 has changed and if this should be addressed in my code.

 People complained about the error box. I plan to replace it with a
 text console (like wxLua -c) so that when running error message will
 stream to it. This will be something that in Lua you can enable or
 disable it, e.g. wxlua.ShowConsoleOnPrint(true/false) or something.

 I think this would be an inferior solution comparing with the error
 box. For me as a developer, it's critical to know when something is
 not working. Right now, if I made a mistake, I get a detailed error
 messages in my face. With a text console, I'll need to keep it on and
 monitor all the time.

 It's even worse for my users. If one of my bugs slips through and
 something is not working (let's say I made a mistake in EVT_CLOSE
 event handler), the window will fail to close without any visible
 indication as to what's wrong (and also possibly leaving the app in
 some inconsistent state without any indication either). And there is
 nothing to report back to me. I can't ask my users to turn the console
 on if something looks strange in their application.

 I don't understand this. The logic to trigger this error is very
 simple, when wxLua starts it saves a pointer to the lua_State* in the
 Lua registry. When an event callback is created the given lua_State*
 is compared with the original lua_State* in the registry and if they
 don't match you must be in a coroutine which means that Lua will give
 you an error about running code in a suspended or dead coroutine so
 instead of that rather cryptic message given later I error out
 earlier.

 It's possible that it's from using two dlls, but I'll need to re-test this.

 Essentially, even with the current binaries I should be able to remove
 socket calls and add explicit type conversion and use it without any
 issues. What I'm concerned about it the crash I was getting:

 If I comment luasocket out, the app crashed somewhere in

Re: [wxlua-users] Preliminary wxLua Binaries for 2.8.12 for MSW

2012-06-30 Thread Paul K

Hi John,

 Download 2.8.12.1 and try it. I have tested with
 luasocket-2.0.2-lua-5.1.2-Win32-vc8.zip downloaded from Lua binaries
 and it works.

This is huge progress; very close to where I'd like to be. I got the
application working with these binaries (including luasocket) and
almost all the functions I tested are working correctly. The UTF
characters are also displayed and copied correctly.

Couple of things that are not working. Shortcuts in the full screen
mode I reported earlier are not working. Either something has changed
or I did not test them correctly with the previous version.

The other thing that is not working is the debugging for wxwidgets
apps I have, which triggers this wxLua: Creating a callback function
in a coroutine is not allowed since it will only be called when the
thread is either suspended or dead. message. This seems to be caused
by the fact that I have two main loop in the application. Your earlier
explanation sheds some light on this:

 The logic to trigger this error is very
 simple, when wxLua starts it saves a pointer to the lua_State* in the
 Lua registry. When an event callback is created the given lua_State*
 is compared with the original lua_State* in the registry and if they
 don't match you must be in a coroutine which means that Lua will give
 you an error about running code in a suspended or dead coroutine so
 instead of that rather cryptic message given later I error out earlier.

It seems like the check is too aggressive, as this functionality has
been working fine before in many different situations (I have never
had a single problem with it) and this is a deal breaker for me. As
far as I can tell, any debugger that executes the main script in a
separate co-routine (as mine does) will get this error.

You can check it with this simple script:

local func,err = loadfile('minimal.wx.lua')
if err then error(err) end
local ok, err = coroutine.resume(coroutine.create(func))
if err then error(err) end

If you run this, you will get minicoro.lua:4: minimal.wx.lua:49:
wxLua: Creating a callback function in a coroutine is not allowed
since it will only be called when the thread is either suspended or
dead., which should not really happen.

 ps. Note that I don't think you ever got error messages from wx.dll...
 When lua.exe is run it does a pcall() on the input file and so it gets
 the error messages, I don't believe it's even possible for wxLua to
 get them. I think what you got are print() statements? Though, it has
 been a long time since 2.8.10 and I have not retested it. I have
 reinstated the error handler, but it's never called, but it's there
 and will pop up a dialog if it ever gets called. Run your program from
 a DOS prompt and the print and error messages will be printed to the
 console.

This part seems to be working as I expect it to work (or even better).
I do get a window with an error AND the same error reported to the
console, which is good. I won't attach the screenshot, but you can see
the same message I'm talking about if you take minimal.wx.lua sample
and change wx.wxMessageBox to wx.wxMessageBox1 (anything that causes
run-time error will do). I get a messageBox with wxLua Runtime Error
title and this error message (also reported to stdout):

wxLua Runtime Error:
Lua: Error while running chunk

stack traceback:

minimal.wx.lua:96: in main chunk

So, my main issue is that check for coroutine that breaks my debugging
and some other functionality. Thank you!

Hi John,

On that coroutine check; it seems like it is the result of this
commit, which specifically added this functionality:
http://wxlua.cvs.sourceforge.net/viewvc/wxlua/wxLua/modules/wxlua/src/wxlcallb.cpp?r1=1.62r2=1.63

I cannot speak to the reasoning behind this (I read the description,
but don't have the background), but I can say that I've extensively
used the previous version in various situations involving co-routines
(including connecting event handlers from coroutines, which is part of
my debugger logic) and have never had problems with the application
because of that.

My suggestion is to revert this change.

I read the thread, but don't see anything that warranted that

the original poster had and in the end the problem was solved:

I've solved the problem by creating a small module that allows to
execute, from a coroutine, a function in the main thread. It helps to
keep the main thread code independant from the coroutine code. My
application works fine now, thanks for the help.

How exactly are you using the coroutines? You're creating one to run a
Lua script and somehow debug it. Can the wxFrame live for longer than
the life of coroutine?

This is for ZeroBraneStudio? How do I run it and where is the code?
There seems to be a lot of binary files there. Where is the code that
uses the coroutines?
https://github.com/pkulchenko/ZeroBraneStudio

You don't need any of those binary files as long as you can run lua
src/main.lua zbstudio command. in fact, just use your binaries with
luasocket and you should be able to run it (just clear the bin/ folder
and put your files and lua.exe there).

No, wxFrame can't live for longer than the life of coroutine. It is
indeed for ZeroBraneStudio, but indirectly; the IDE itself doesn't
depend on this, but the debugging component (provided by MobDebug:
https://github.com/pkulchenko/MobDebug) does.

The logic in question is part of the controller() function and is a
completely generic code:

local coro_debugee = coroutine.create(debugee)
debug.sethook(coro_debugee, debug_hook, lcr)
local status, err = coroutine.resume(coro_debugee)

It creates a coroutine for debugee (which is a function created as a
result of loadstring/loadfile, for example, debugee =
loadfile('minimal.wx.lua')), sets a debug hook on it and resumes it.
All wxlua logic is encapsulated there, but with this fix the execution
fails.

The issue is that doing this is dangerous and sometimes you have to
stop people from trying to shoot themselves in the foot.

It may be a valid reason in some cases, but I think in this case it
broke a completely legitimate use of this functionality. In fact, in
the original case the user was getting a reasonably informative error.

I would test the old version to see if the behavior has changed, in
any case it would be something that wxWidgets has changed. It may just
be that when the menu is removed the accelerators are removed too. You
can supplement or replace them using a wxAcceleratorTable.

As explained in the code you've seen, there are many things wrong with
allowing it, the least of which is that you definitely cannot call
coroutine.resume() from the event handler in the coroutine.
Search for cannot resume non-suspended coroutine here:
http://wxlua.svn.sourceforge.net/viewvc/wxlua/trunk/wxLua/modules/lua/src/ldo.c?revision=100view=markup

Just to elaborate a bit on use cases. I currently use it for

I'm having troubles compiling monolithic dylib on MacOS. I've read the

[wxlua-users] Multiple view with StyledTextCtrl

2012-07-26 Thread Paul K

Does anyone have an example of how I can implement multiple views in
wxLua? I have read through this description
(http://www.yellowbrain.com/stc/mult_views.html), but still can't
figure out what the required calls are.

What I want to do is quite simple: I have an editor window that I want
to display and I also need a second window that will only show *some
of the lines* shown in the editor window. If the lines are updated in
the editor window, they should be updated in the other window. I'll
hide some of the lines in the other window using HideLines/ShowLines
(http://www.yellowbrain.com/stc/folding.html#hidelines).

What is the minimum set of required commands to add a second view to
an existing wxstc.wxStyledTextCtrl object? Thank you.

Paul.

[wxlua-users] Compiling monolithic version on Windows (using 2.8.12.2)

2012-08-08 Thread Paul K

Hi John,

I've read through the installation/compilation instructions and am
still searching for a combination of settings I need to apply to get
one wx.dll produced.

Here is the command I used:

mingw32-make -f makefile.gcc BUILD=release UNICODE=1 SHARED=1
MONOLITHIC=1 WX_MONOLITHIC=0 WX_SHARED=0 USE_LUAMODULE=1
USE_WXBINDGL=0 LINK_DLL_FLAGS=-shared

I compiled wxwidgets with SHARED=0 and MONOLITHIC=0 to genterate .a
files as I expect those to be linked into wx.dll
I specified SHARED=1 and MONOLITHIC=1 for wxlua. For some reason it
still tries to generate all the individual DLLs, like
wxlua_msw28u_wxlua.dll.

Also, I get an error on linking against _gl library
(mingw32/bin/ld.exe: cannot find -lwxmsw28u_gl) and I indeed don't
have that library. I tried adding USE_WXBINDGL=0, but it didn't help.
What parameter do I need to provide to skip gl library?

Can you share the command line for mingw that should get me wx.dll or
settings for vs you used to build wx.dll? Thank you.

Paul.

P.S. btw, until I added LINK_DLL_FLAGS=-shared, I was getting

Creating library file: ..\..\..\lib\gcc_dll\liblua5.1.a
./libmingw32.a(main.o): In function `main':
C:\MinGW\msys\1.0\src\mingwrt/../mingw/main.c:73: undefined reference
to `WinMain@16'

error, even though LINK_DLL_FLAGS is set at the top of the makefile:

# Compiler flags to link shared library
LINK_DLL_FLAGS ?= -shared

P.P.S the installation instructions refer to mingw32-make -f
makefile.mingw, but there is no .mingw makefile, only .gcc one.

Re: [wxlua-users] Compiling monolithic version on Windows (using 2.8.12.2)

2012-08-09 Thread Paul K

Hi John,

I think I'm close, but still not there yet. I did get luawx.dll
library, but it's 12+M in size and it depends on
libwxlua_lua51-wx28mswu-2.8.12.dll (which seems to be a renamed lua
dll). There are also several other libraries, but the application
seems to work without them:

12,318,932 libwx.dll
 3,480,509 libwxlua-wx28mswu-2.8.12.dll
11,973,978 libwxlua_bind-wx28mswu-2.8.12.dll
 3,413,790 libwxlua_debug-wx28mswu-2.8.12.dll
   215,408 libwxlua_lua51-wx28mswu-2.8.12.dll
 3,405,545 libwxlua_socket-wx28mswu-2.8.12.dll
61,395 lua.exe
   219,561 luac.exe

Why do all the names start from libwx? Also, the library seems to be
much larger in size than yours (12M vs. 5.5M) and this is in
MinSizeRel configuration. I couldn't find any setting that would
affect the size.

Is this possible to link against an existing *real* lua.dll
(lua5.1.dll or lua51.dll), rather than against
libwxlua_lua51-wx28mswu-2.8.12.dll?

All I need is a standalone wx.dll I can compile in Unicode
configuration that I can use with my lua dll. Is this possible?

Paul.

 Please use the CMake generated build files now. The old ones are not
 nearly configurable enough. I recommend building static wxWidgets libs
 and then you will get a single wx.dll with no other dependencies.

[wxlua-users] GetCwd() doesn't return unicode path on windows

2012-08-16 Thread Paul K

It seems like I can't get a proper unicode path from GetCwd() on
windows using wxLua 2.8.12.2.

I'm running the following code:

wx.wxFileName.SetCwd(D:\\Lua\\下载\\); print(wx.wxFileName.GetCwd())

and this prints D:\Lua\?? whereas I expect the original path to be
printed. SetCwd() returns true. I look at some other calls, and others
I checked seem to be working correctly, for example,
wx.wxStandardPaths.Get():GetExecutablePath() returns
D:\\Lua\\下载\\zbstudio.exe (which is correct).

Is this a bug in GetCwd() or am I doing something wrong with it?

Paul.

[wxlua-users] How to disable logging window with error message in wxlua?

2012-08-16 Thread Paul K

Hi all,

I'm working with an application that saves data in files and some of
the operations may trigger file errors. I'm handling those errors
myself and don't want to see the standard error message shown by
wxwidgets. How do I disable it? Here is the code that I have:

  local file = wx.wxFile(filename, wx.wxFile.write)
  file:Write(something, #something)

If the file is write protected, I get can't open file '...' (error 5:
access is denied). I know, I can check for that condition, but this
is not what the question is about. I'd like to disable that message.

Here is what I tried so far:

1. use wxLogNull. I read C++ examples, but not sure how this should be
used in wxlua (according to examples, you just need to instantiate
this logNull object):

local log = wx.wxLogNull()
file:Write()
log:delete()

This has no effect.

2. use SetActiveTarget()

local log = wx.wxLog.SetActiveTarget(wx.wxLogNull())
file:Write()
wx.wxLog.SetActiveTarget(log)

This doesn't work as SetActiveTarget expects wxLog object, but
wxLogNull doesn't seem to be inherited from wxLog (according to wxlua
docs).

3. use EnableLogging on either wx.wxLogGui() or wx.wxLog()

local curr = wx.wxLogGui().EnableLogging(false)
file:Write()
wx.wxLogGui().EnableLogging(curr)

This has no effect.

What is the right way to (temporarily) disable logging such that I
don't get the log window? Thanks.

Paul.

Re: [wxlua-users] How to disable logging window with error message in wxlua?

2012-08-16 Thread Paul K

Hi John,

 This does not show the error dialog for me in Linux.

it seems like you need to have a frame open to see the effect (your
code works regardless of whether LogNull is there). Try the code
below.

The solution is indeed to use local log = wx.wxLogNull(), but it
needs to be used *before* wxFile constructor, because this is where it
is failing (not in the Write method as I thought initially). Thanks
for getting me on the right track.

require wx

function FileWrite(file,content)
  -- local log = wx.wxLogNull()  LogNull code should be here
  local file = wx.wxFile(file, wx.wxFile.write)
  if not file:IsOpened() then return nil, wx.wxSysErrorMsg() end

  local log = wx.wxLogNull()
  file:Write(content, #content)
  file:Close()
  log:delete() -- this doesn't seem to be needed
  return true
end

function main()
-- create the wxFrame window
local frame = wx.wxFrame( wx.NULL,-- no parent for
toplevel windows
wx.wxID_ANY,  -- don't need a wxWindow ID
wxLua Minimal Demo, -- caption on the frame
wx.wxDefaultPosition, -- let system place the frame
wx.wxSize(450, 450),  -- set the size of the frame
wx.wxDEFAULT_FRAME_STYLE ) -- use default frame styles

-- show the frame window
frame:Show(true)

if not FileWrite(/my-read-only-file, something) then
  wx.wxMessageBox(Unable to save file., Error, wx.wxOK + wx.wxCENTRE)
end
end

main()

wx.wxGetApp():MainLoop()

Re: [wxlua-users] GetCwd() doesn't return unicode path on windows

2012-08-19 Thread Paul K

Hi John,

 Using the unicode build right?

Yes. Everything else Unicode-related is working as far as I can tell.

 Does wx.wxFileName.FileExists(SomethingInThatDir.txt) work, showing
 that SetCwd() worked?
 If so then, it'd be a problem with GetCwd(), but I cannot think of any
 reason why it wouldn't work off the top of my head...

yes, it does seem like the problem is with GetCwd, and it should be
easy to reproduce:

 wx.wxFileName.SetCwd([[D:\Lua\下载\下载\]]); 
 print(wx.wxFileName.FileExists(foo.lua)); print(wx.wxGetCwd()); 
 print(wx.wxFileName.SetCwd(wx.wxGetCwd()))
true
D:\Lua\??\??
false

As you can see, the file is there, but using the result of GetCwd to
set it as the current folder fails (returns false the second time).

Re: [wxlua-users] debugging lua scripts

2012-08-27 Thread Paul K

Hi Milind,

I quickly tried that in wxLua, but couldn't figure out how to specify
the folder to run scripts in so that loadfile and io.open would work.

I also tried to do this in ZeroBrane Studio
(https://github.com/pkulchenko/ZeroBraneStudio) and it seems like it
may work for you (the IDE is wxlua based). I'm not sure what your code
looks like, but let's say you have loadedfile.lua script that you are
trying to load and it has the following lines:

-- loadedfile.lua
print 123
print 456
function foo()
  print foo
end

You also have loadfile.lua script which has something like this:

-- loadfile.lua
--local func = loadfile('loadedfile.lua')
local f = assert(io.open('loadedfile.lua'))
local str = f:read('*all')
f:close()
local func = loadstring(str, 'loadedfile.lua')
func()
foo()
print 'Done'

If you open both of these files in ZeroBrane Studio and start
debugging with loadfile.lua being in the active editor window, you
should be able to step through both of them. You can also set a
breakpoint on either of the files and it should work.

Note that I added loadedfile.lua as a parameter for loadstring(),
which informs the debug interface as to where to search for the source
code.

Paul.

[wxlua-users] [ANN] ZeroBrane Studio 0.32; now with unicode support, moai integration, and wxlua 2.8.12 upgrade

2012-09-03 Thread Paul K

(crossposting to wxlua-users as this is a wxlua-based application;
thanks to John Labenski for all the support and assistance with wxlua
upgrade.)

ZeroBrane Studio is a lightweight Lua IDE with code completion, syntax
highlighting, live coding, remote debugger, code analyzer, and
hypertext/markdown formatting support for integrating learning
materials (examples and demos provided).

Thanks to everyone who provided feedback and suggestions. Here is the
summary with the most important changes (full changelog:
https://github.com/pkulchenko/ZeroBraneStudio/blob/master/CHANGELOG.md):
- Added Unicode support for file encoding and file paths on Windows (fixes #30).
- Added Moai integration and debugging (including debugging of Moai
threads and callbacks).
- Added refresh of Stack and Watch windows after executing a statement
in remote shell.
- Added display of complex values on multiple lines in shell with '='.
- Added calltip on mouseover for functions during editing and for
variables/expressions during debugging.
- Added configuration options to set paths to lua and love2d executables.
- Added support for coroutine debugging with stepping through
coroutine.resume/.yield calls.
- Updated wx.dll to wxlua 2.8.12.2 and wxwidgets 2.8.12.
- Signed zbstudio app and executable to avoid issues with files not
being saved without admin privileges and to remove warning about
'unknown publisher' on windows (fixes #25).

There were several changes to improve running on Linux, but more
complete Linux support is still work in progress.

I also posted a screencast that shows live coding with Löve:
http://notebook.kulchenko.com/zerobrane/live-coding-with-love; here is
a similar screencast with a demo running on OSX:
http://nikdudnik.com/post/30067678839/ive-spent-last-day-looking-for-a-suitable
(Nikita only saw mine after he published his screencast).

The code and the packages (.dmg, .exe, and .zip) are available on
github: https://github.com/pkulchenko/ZeroBraneStudio/downloads.

Re: [wxlua-users] mingw compiling wxlua problems

2012-09-17 Thread Paul K

Hi Victor,

I have always wanted to require wx in a lane but because of only once dll
initialization it does not work. I am able to require wx from a lane if it
has not been required from the main lua_State.

I might have seen a similar issue, but for a different reason: I
wanted to be able to load and run wx from a co-routine. We had a
discussion with John couple of months ago as to why this may not be
working with wxlua 2.8.12 (even though it was working before with
2.8.7 and 2.8.10). You can see the discussion here:
http://www.mail-archive.com/wxlua-users@lists.sourceforge.net/msg03010.html.
Essentially, there was a fix that was applied in rev100 (in svn),
which was then partially rolled back in rev104
(http://wxlua.svn.sourceforge.net/viewvc/wxlua/trunk/wxLua/modules/wxlua/src/wxlcallb.cpp?r1=100r2=104pathrev=104).
The partial rolled back caused the issue with aborting a coroutine
when wx module was loaded into that coroutine space (the application
was crashing).

I know it's a long shot and it may be just a coincidence that your
symptoms look similar, but you may want to try to comment out this
line in the diff I referenced (I haven't checked where it is in the
current revision):

m_wxlState = wxLuaState(wxlState.GetLuaState(),
wxLUASTATE_GETSTATE|wxLUASTATE_ROOTSTATE);

At least that fixed the issue for me (without any consequences as far
as I can tell). I've been using this patched version for about 6 weeks
running on Windows, Mac and Linux.

Thank you for answering. I have solved the problems in my lualanes and wx
application. It seems that something is not working if I do
requiresomething inside a lane that has not been required in the lua_state
where wx is loaded. When the lane is finished wx gets hanged (I guess that
when unloading the dll) so I am now requiring everything in the main
lua_state even if I dont need it. Another problem came from wx defining bit
instead of wx.bit so when I use bit from luaBitOp lanes get confused also (I
renamed it bitOp for solving).

I have always wanted to require wx in a lane but because of only once dll
initialization it does not work. I am able to require wx from a lane if it
has not been required from the main lua_State. Do you thing it could be
changed anyhow so that luaopen_wx does not return lua_getglobal(L, wx);?
Would that break wx?

[wxlua-users] Detecting opening wxChoice on Mac

2012-09-19 Thread Paul K

Hi All,

I have a wxChoice dropdown, which I'm populating on wx.wxEVT_SET_FOCUS
event. Unfortunately, this event is not triggered on Mac, which seems
to be a feature. I found a ticket related to this:
http://trac.wxwidgets.org/ticket/10047.

The fix seems to be using EVT_CHILD_FOCUS instead of EVT_SET_FOCUS
event, but my problem is that *neither* is triggered on Mac (tested
with wxlua 2.8.12.2 on OSX 10.7). I understand that this is probably
wxwidget issue (if it's indeed a real issue), but I'm interested to
hear if this worked for someone on Mac and if not, what workaround may
I use.  All I want is to be able to detect when a wxChoice control is
activated. Thank you.

Paul.

[wxlua-users] wx.wxMOD_* constants not defined on Mac

2012-09-19 Thread Paul K

Hi John,

I just noticed that for some reason wx.wxMOD_NONE is not defined on
Mac (wxlua 2.8.12.1) while it is defined correctly on Windows. This
breaks logic like event:GetModifiers() == wx.wxMOD_NONE. In fact, it
seems like none of the wx.wxMOD_* constants is defined on Mac.
GetModifiers() returns correct values for those modifiers (I checked
Alt/Cmd/Ctrl and they match the docs).

I haven't had a chance to check the code yet, but wanted to let you
and others know (as this led to some subtle bugs for me).

Paul.

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

2012-10-01 Thread Paul K

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.

 Hi All,

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

   local proc = wx.wxProcess(wx.NULL, wx.wxPROCESS_REDIRECT)
   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] Can't read output with wxPROCESS_REDIRECT and wxEXEC_ASYNC

2012-10-01 Thread Paul K

Hi John,

 Please read the description of wxProcess where they describe how to
 use the streams. You will also want to check the status of the process
 before trying to use it as well.

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.

Paul.

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

[wxlua-users] Checkboxes don't react to clicks in editor.wx.lua on Mac OSX

Hi John,

One of the users noticed that checkboxes in Find/Replace dialogs in
ZeroBraneStudio don't react to clicks on Mac OSX; I tested
Find/Replace dialog in your editor.wx.lua sample and it shows exactly
the same issue (using wxlua 2.8.12.1). Other checkboxes (for examples
in controls.wx.lua) work as expected, so I think it's not wxCheckBox
problem. I suspect it's some sort of interaction between sizers and
controls (and only on Mac OSX as both Windows and Linux versions work
correctly). Radioboxes on the same panel also work correctly. Any help
or ideas to test would be appreciated.

Paul.

2012-10-16 Thread Paul K

Hi John,

Ok, I narrowed it down to a problem with wxStaticBoxSizer as the
following short script shows (this is with wxlua 2.8.12.1 and
wxwidgets 2.8.12 running on OSX10.7.4):

require wx
local findDialog = wx.wxFrame( wx.NULL, wx.wxID_ANY, Checkbox in sizer demo,
  wx.wxDefaultPosition, wx.wxDefaultSize, wx.wxDEFAULT_FRAME_STYLE)
local wholeWordCheckBox  = wx.wxCheckBox(findDialog, wx.wxID_ANY,
Match whole word)
local matchCaseCheckBox  = wx.wxCheckBox(findDialog, wx.wxID_ANY, Match case)
local wrapAroundCheckBox = wx.wxCheckBox(findDialog, wx.wxID_ANY,
Wrap around)

local optionSizer = wx.wxBoxSizer(wx.wxVERTICAL, findDialog)
optionSizer:Add(matchCaseCheckBox,  0, wx.wxALL + wx.wxGROW + wx.wxCENTER, 3)
optionSizer:Add(wrapAroundCheckBox, 0, wx.wxALL + wx.wxGROW + wx.wxCENTER, 3)

local optionsSizer = wx.wxStaticBoxSizer(wx.wxVERTICAL, findDialog,
Options )  change to wxBoxSizer to fix
optionsSizer:Add(optionSizer, 0, 0, 5)

local optionScopeSizer = wx.wxBoxSizer(wx.wxHORIZONTAL)
optionScopeSizer:Add(optionsSizer, 0, wx.wxALL + wx.wxGROW + wx.wxCENTER, 5)
optionScopeSizer:SetSizeHints(findDialog)
findDialog:SetSizer(optionScopeSizer)
findDialog:Show(true)
wx.wxGetApp():MainLoop()

Replacing wxStaticBoxSizer with wxBoxSizer fixes the issue (but
obviously changes the layout of the form). The problem is only on OSX
(Windows and Linux show no issue) and it seems like it's a wxwidgets
issue, but I can't find anything about it online, so I'm not 100%

I'm looking for a fix/workaround. Is there an easy way to check what
object gets those clicks and to propagate the clicks to my checkboxes?

Re: [wxlua-users] Checkboxes don't react to clicks in editor.wx.lua on Mac OSX [fixed]

2012-10-16 Thread Paul K

In the best tradition of answering my own question, the solution was
easy: create wxStaticBox (or wxStaticBoxSizer) *before* checkboxes are
created.

There seems to be a bug (or feature) in how the order in event
traversal is handled and if the staticbox is created after the
checkboxes, none of the checkboxes get their events on OSX (you can
still click on the area of the checkbox label if it sticks outside of
the static box).

 Hi John,

 One of the users noticed that checkboxes in Find/Replace dialogs in
 ZeroBraneStudio don't react to clicks on Mac OSX; I tested
 Find/Replace dialog in your editor.wx.lua sample and it shows exactly
 the same issue (using wxlua 2.8.12.1). Other checkboxes (for examples
 in controls.wx.lua) work as expected, so I think it's not wxCheckBox
 problem. I suspect it's some sort of interaction between sizers and
 controls (and only on Mac OSX as both Windows and Linux versions work
 correctly). Radioboxes on the same panel also work correctly. Any help
 or ideas to test would be appreciated.

Re: [wxlua-users] WxApp::FilterEvent available in wxlua?

2012-10-17 Thread Paul K

Hi John,

 You should be able to call Connect() on the window you're interested
 in getting them from.

 window:Connect(wx.wxEVT_KEY_DOWN, Lua function)

I'm looking for reducing the number of windows to check as there are
many that can trigger those events. I tried attaching the handlers to
the main window, but I don't get the events I need. I think the
difference is that FilterEvent is called before any of the regular
handlers are called, but the handler that is attached to the main
window is called only if the event is propagated up the chain and it
depends on how that event is handled.

Paul.

 Is there a way to use it with wxlua or an alternative way to at least

Re: [wxlua-users] WxApp::FilterEvent available in wxlua?

2012-10-18 Thread Paul K

Hi John,

 A wxIdleEvent event is sent after every event or batch of events so
 you are guaranteed to get it. You could be tricked that a user was
 active with your app if a different window is dragged on top and a
 paint event sent, but does that matter?

I saw that code, but he is using GetLastInputInfo, which is Windows
only and I need something that works on Windows, OSX, and Linux. It is
also tracking *user* idle time (across all applications), rather than
application idle time (which is what I am after).

I also couldn't get wxIdleEvent to work as I'd expect, because it's
always generated on Windows (I get a stream of IDLE events), but only
after some other events on OSX and Linux (as documented).

Also, I registered EVT_KILL_FOCUS handler on the main frame in the
application, but it's not triggered when the focus is changed to
another application.

Right now I simply set a timer for X/2 seconds (where X is the period
I want to track) and track document modification events that happen
during that time. I don't get the exact interval I need, but it's not
critical; I'm never more than X/2 seconds off. I was looking for
something more centralized and simpler than what I have now, but
couldn't find it.

Paul.

 If you can you explain what you are trying to do I might be able to help.

 Sure; I'm trying to detect idle time in the application when a user
 doesn't do any activity for X seconds. Any activity is defined as
 EVT_MOTION and EVT_KEY_DOWN events, but I'll settle for EVT_KEY_DOWN
 if it's difficult to track both. I don't want to keep adding my
 handlers to all the components I have and am looking for as few places
 to modify as possible.

 How about something like this?

[wxlua-users] [ANN] ZeroBrane Studio 0.33; now with Linux support, Gideros debugging, and MOAI auto-complete

2012-10-29 Thread Paul K

ZeroBrane Studio is a lightweight Lua IDE with code completion, syntax
highlighting, live coding, remote debugger, code analyzer, and
hypertext/markdown formatting support for integrating learning
materials (examples and demos provided).

The IDE is available at http://studio.zerobrane.com/. The most recent
version implements a large number of features with several most
important ones being:

- Added Linux support (tested in 32bit and 64bit configuration on
Ubuntu and Mint distributions).
- Added Gideros debugging, auto-complete, and live coding.
- Added Moai auto-complete.
- Added syntax aware indentation.
- Added re/storing open files and interpreter when switching project folders.

Full details are in the changelog:
https://github.com/pkulchenko/ZeroBraneStudio/blob/master/CHANGELOG.md.
Some users also tested and reported that ZeroBrane Studio and MobDebug
work with clients running Lua 5.2, which may be of interest; you only
need to use David's compat_env
(https://raw.github.com/davidm/lua-compat-env/master/lua/compat_env.lua)
to get the debugger working. This way you can run ZeroBrane Studio
(using Lua 5.1) and debug applications that use Lua 5.2 interpreter.

Thank you all for your continuing support in the development of this IDE!

Paul.

Re: [wxlua-users] wxEVT_STC_STYLENEEDED is not called in wxlua 2.8.12.2?

2012-11-15 Thread Paul K

Hi John,

 If you choose to use the container to do the styling you can use the
 SCI_SETLEXER command to select SCLEX_CONTAINER, in which case the
 container is sent a SCN_STYLENEEDED notification each time text needs
 styling for display.

You are absolutely right. In fact, I was reading this fragment and
somehow missed that STYLENEEDED is going to be *only* called when the
lexer is set to SCLEX_CONTAINER.

 I think the idea is that you will have to style everything all the
 time. Though, I don't remember having tried it myself.

Ok, related question then. Is it possible to use SCLEX_CONTAINER, but
still make a call that will apply styling using some lexer (for
example, Lua) and I'll do the rest of the styling as needed?

Paul.

Re: [wxlua-users] GetLineVisible always returns true?

2013-02-25 Thread Paul K

Hi John,

 This is how I do it in stedit.cpp in the modules/wxstedit/src dir.

Should have checked there; I came up with very similar code, but also
included DocLineFromVisible:

function isLineVisible(line)
  local firstline = editor:DocLineFromVisible(editor:GetFirstVisibleLine())
  local lastline = math.min(editor:GetLineCount(),
editor:DocLineFromVisible(editor:GetFirstVisibleLine() +
editor:LinesOnScreen()))
  return line = firstline and line = lastline
end

This is needed because lines can be wrapped (as they are in my case),
but LinesOnScreen counts those as well (so the number on the screen
will be larger than the number in the document).

Paul.

 Yes. It doesn't have the clearest name. I think you know this, but the

 message names.

 This is how I do it in stedit.cpp in the modules/wxstedit/src dir.

 int first_line= top_line  0 ? GetFirstVisibleLine() : top_line;
 int line_count= GetLineCount();
 int lines_visible = LinesOnScreen();
 int last_line = bottom_line  0 ? wxMin(line_count, first_line
 + lines_visible) : bottom_line;

Re: [wxlua-users] Patch to wxlua to allow setting event handlers from coroutines

2013-02-28 Thread Paul K

Hi John,

To be sure, for debugging you create a coroutine then run the whole
app in that coroutine state using debug hooks and yields to pause it?

This is exactly correct. Debug hook is registered to that coroutine,
but the debugger itself runs in yet another coroutine.

What happens when a wxLua app is paused at a breakpoint and an event
handler is called? Don't you get an error saying something about
resuming a suspended coroutine or is the coroutine not yielded to
pause the execution?

No; never got this message. The application itself is suspended, so it
can't really receive any messages. In fact, I actually *do* set event
handlers from the debug coroutine while it's suspended to minimize
busyness of the application (it's around lines 540-550 in
mobdebug.lua), but I have never seen any crashes related to that.

I would also like to understand what the advantages of the coroutine
method of debugging are over the wxLua blocking socket method?

I don't use wxlua sockets because the debugger uses exactly the same
mechanism running wxlua or any other lua application.

In any case, normally anyone who tries to connect an event handler in
a coroutine will crash their program in a very hard to debug way,
especially if the coroutine they installed the callback in gets
garbage collected.

It seems like this has been working fine for me for as long as the
code that handles the callback is in the same coroutine as the code
that sets it (which is my case).

What I also do to support live coding is to call error from the
debug hook in the main coroutine, which allows me to reload the code
while the application is running. This is when it crashes with the
current wxlua code and doesn't crash with the patch. It seems like the
line I commented out in the patch does something to the Lua state that
causes the crash.

I would like to find a way to have it work for your case, but also not
frustrate new wxLua users who might imagine that they can somehow
create a threaded GUI app using coroutines, not understanding that
events are already sent asynchronously as has happened in the past.

Maybe it is enough to simply have a strongly worded comment in the
documentation, but please explain a little about your debugging
methods.

A strongly worded comment would definitely make sense. Please let me
know if you'd need any additional details or a small example that
demonstrates the issue.

Paul.

[wxlua-users] Compilation errors with latest wxlua (2.8.12.3; rev 165)

Hi John,

I tried to compile the latest wxlua and ran into compilation errors
(both on OSX and Windows). I also tried with rev 163 (before Lua 5.2

error messages I got are at the bottom of the email.

Tangentially related; would it be possible to expose

While we are on the topic of building wxlua, is it possible to provide
a parameter for configure to disable building of all
executables/applications and also disable building of debug/socket
libraries (which I don't need)? I regularly rebuild from source and
this would noticeably speed up the process (I only need
wx.dll/dylib/so). Thank you.

 Hi John,

 I tried to compile the latest wxlua and ran into compilation errors
 (both on OSX and Windows). I also tried with rev 163 (before Lua 5.2
 changes) and compiled it successfully (also on both platforms). The
 error messages I got are at the bottom of the email.

 Thanks for reporting, it should be fixed now.

 Tangentially related; would it be possible to expose
 wxstc.wxStyledTextCtrl.GetLibraryVersionInfo in the API? I'd like to
 show Scintilla version number in the About screen.

 Sure.

 While we are on the topic of building wxlua, is it possible to provide
 a parameter for configure to disable building of all
 executables/applications and also disable building of debug/socket
 libraries (which I don't need)? I regularly rebuild from source and
 this would noticeably speed up the process (I only need
 wx.dll/dylib/so). Thank you.

 You can already choose to build whatever libs and apps you want right
 now. Choose the project you want to build in MSVC or run make help
 for GCC to list all the targets.

 Regards,
  John

 There is one small issue when I select wxLuaModule as the only target

 To be honest, this this not something I have any interest in
 implementing. Even if it was made to work by silently ignoring missing
 parts then people who wanted to use the wxLua package as a whole may
 end up missing parts by accident and that would be far worse then you
 having extra parts. I recommend simply building it as is and taking
 the parts you want.

That is what I ended up doing. Thanks for taking look at this.

[wxlua-users] wxDir is missing Traverse method in wxlua 2.8.12

2013-03-15 Thread Paul K

Hi John,

I noticed that wxlua is missing the Traverse method in wxDir object
(http://docs.wxwidgets.org/2.8/wx_wxdir.html#wxdirtraverse).

Is it possible to add it or is there something more fundamental that
prevents it? I'd also like to make sure that wxDirTraverser
(http://docs.wxwidgets.org/2.8/wx_wxdirtraverser.html#wxdirtraverser)
will work as it's required for Traverse to be useful. Thank you!

2013-03-15 Thread Paul K

Hi John,

Thank you for the link to Traverse implementation; I should have
looked there myself. VZ uses GetFirst and GetNext, whereas I actually
use FindFirst and FindNext. I'm not sure what exactly the differences
are, but I'll re-implement Traverse in Lua and see if it is
sufficiently fast for my needs.

Paul.

 Hi John,

 I do that now (I use GetFirst() and GetNext()), but it's a bit slow
 for my purposes. GetAllFiles is much faster, but my main problem with
 it is that I can't exclude directories I don't need (for example,
 .git, .svn and others), and those can be quite slow to scan (due to a
 large number of directories and files).

 For example, when I try GetAllFiles it scans a folder with 278 files
 (including subfolders, most of these are in .git folder), it takes
 0.8s to scan (and subsequent runs only take 0.08s or so). Same folder
 without .git subfolder takes only 3ms or so to scan (17 files).

 I'm hoping that the Traverse method would give me a way to do it fast,
 but also allow me to filter out those folders I don't need.
 Unfortunately I can't test it without having access to it.

 Please use GetAllFiles() or roll your own GetFirst() GetNext()

 An example of how to do that is here, see wxDir::Traverse()
 http://svn.wxwidgets.org/viewvc/wx/wxWidgets/trunk/src/common/dircmn.cpp?view=markup

 I don't really see any gain in using it for Lua programs as it just
 adds a layer of complexity and without enumeration type-safety can
 cause more problems than it would solve.

[wxlua-users] How to configure wxlua to not link wxpng library?

2013-03-17 Thread Paul K

Hi John,

I ran into an issue with configuring wxlua to use system libpng
library. I tried both --with-libpng=builtin and --with-libpng=sys, but
I get exactly the same result.

This discussion
(https://groups.google.com/forum/?fromgroups=#!topic/wx-users/2QWQD0qUVUc)
indicates that it's better to use a system library, but I can't
configure wxlua to *not* link builtin library as can be see from this
output from cmake:

-- * - wxWidgets_LIBRARIES =
-L/home/paul/zbs/build/deps/lib;-pthread;;;/home/paul/zbs/build/deps/lib
/libwx_gtk2u_stc-2.9.a;/home/paul/zbs/build/deps/lib/libwx_gtk2u_aui-2.9.a;/home/paul/zbs/build/deps/lib
/libwx_baseu_net-2.9.a;/home/paul/zbs/build/deps/lib/libwx_gtk2u_html-2.9.a;/home/paul/zbs/build/deps/lib
/libwx_gtk2u_adv-2.9.a;/home/paul/zbs/build/deps/lib/libwx_gtk2u_core-2.9.a;/home/paul/zbs/build/deps/lib
/libwx_baseu-2.9.a;-lwxscintilla-2.9;-pthread;-lgthread-2.0;-lrt;-lX11;-lXxf86vm;-lgtk-x11-2.0;-lgdk-x11-2.0;-latk-
1.0;-lgio-2.0;-lpangoft2-1.0;-lpangocairo-1.0;-lgdk_pixbuf-2.0;-lcairo;-lpango-1.0;-lfreetype;-lfontconfig;-lgobject-
2.0;-lglib-2.0;-lwxregexu-2.9;-lwxjpeg-2.9;-lwxpng-2.9;-lwxzlib-2.9;-ldl;-lm

(note the last last that includes -lwxpng-2.9). I tried (using brute
force) to exclude wxpng from the link command, but failed. Ideally
wxlua should somehow check if the library is configured as builtin
or sys, but for now I just need to check if this is going to work
for me, so, I'm fine with modifying it manually. I need to exclude
libpng as it creates problems with systems libraries required by GTK
on Linux.

What is the way for me to tell wxlua *not* to include wxpng-2.9? Thank you.

Paul.

Hi John,

As far as I understand, wxstedit is only needed when wxlua is compiled
with wxwidgets 2.8.12; it's no longer required for 2.9.x. Or am I
mistaken?

If it's not needed for 2.9.x, then svn checkout --ignore-externals
can probably be used to skip it (I can't test it at the moment).

[wxlua-users] RawControlDown, SetRawControlDown, wxMOD_RAW_CONTROL, wxACCEL_RAW_CTRL, and WXK_RAW_CONTROL not present in wxlua 2.8.12.3

2013-04-09 Thread Paul K

Hi John,

Would it be possible to add missing calls and constants? Thank you.

BTW, ControlDown() has changed its behavior between 2.8 and 2.9 wxwidgets
as it used to mean Ctrl on all platforms (with CmdDown() meaning Ctrl/Cmd),
but it now means Ctrl/Cmd (and CmdDown() is deprecated). RawControlDown()
replaced the old ControlDown(). wxMOD_* modifiers have been updated in a
similar way.

Just wanted to let you and others know as I got burned by this a bit...

[wxlua-users] How to install custom EVT_LUA_ERROR handler?

2013-04-22 Thread Paul K

Hi John,

I'm trying to provide my own custom error handler that will replace
the default dialog shown after run-time errors in wxlua
(wxLuaModuleApp::OnLuaError), but I'm having trouble with it as
wxEVT_LUA_ERROR doesn't seem to be available to Lua scripts.

Was that intentional and is it possible to make it available as it
would be very convenient for my app to capture and report errors and
to provide a customized error message?

I also tried providing my own debug.traceback call to hadle this (and
to return nil from it), but wxlua still shows an empty dialog in this
case (and I'd prefer the dialog to be completely removed). Having
ability to assign EVT_LUA_ERROR handler would be the easiest/proper
way to handle this. Thank you.

I just started using the studio and it is very good. Only thing is when I go

You can change the executable that is used to run/debug the scripts.
The example is here

and instruction are here
(http://studio.zerobrane.com/doc-configuration.html)

Also is the UI done in wxlua? If yes how do you implement the main text with
down with different colors, breakpoint mark and line numbers?

Yes, everything is done in wxlua. The editing component is Scintilla,
so all I need to do is to configure it to display proper margins,
markers, and set colors I want. This is mostly done in
src/editor/editor.lua (CreateEditor) and src/editor/style.lua (where
all the style information is processed).

The only difference should be is that wxluafreeze includes wx library
statically compiled (so you don't need anything else) and in other
cases your executables expect wx.dll.

I'm not sure what graphics are different. Can you do two screenshots
and mark the differences on them? I don't use wxluafreeze, but I
wouldn't expect to see any differences.

Is there a difference of launching the program through Lua or through
 wLua? I am not sure what is different in wLua because it is just a 35KB

 execute the program while wxluafreeze still can execute the program without

 So what is the difference?

[wxlua-users] How to use wxHandleFatalExceptions and OnFatalExceptions?

2013-06-03 Thread Paul K

Hi John,

I've been looking for ways to catch and report run-time errors in the
application.  Lua errors are covered with your recent support for
EVT_LUA_ERROR (http://sourceforge.net/p/wxlua/svn/180/), but there are
still fatal exceptions in the application that may happen.

As far as I can see from wxwdigets docs, these are controlled by
wxHandleFatalExceptions and OnFatalExceptions; wxlua does provide a
methods for wxHandleFatalExceptions, but I don't see anything similar
to OnFatalExceptions? How do I get set up a handler that gets called
when a fatal exception happens? It would be super useful to also have
a way to access Lua state from it to gather Lua stack information to
include in the crash report. Or is there an existing alternative I am
missing?

Would it be possible to use OnFatalExceptions to set a callback (a Lua
function) that will be called when a fatal exception happens?

While we are on the topic of crash reports, there is wxDebugReport,
but it doesn't seem to be available in the binding. Does it make sense
to expose it, or is it better try to gather and report as much as
possible at the Lua level?

Also, there are some other methods documents (OnExceptionInMainLoop
and OnUnhandledException) and I can't figure out if these are also
needed or if OnFatalExceptions is enough if exposed in wxlua. Thank
you!

Paul.

[wxlua-users] Strange (occasional) crash in wxLuaState::LuaPCall

2013-06-12 Thread Paul K

Hi John,

I got several reports (from the same machine) of crashes in my
application when a user types something in wxSTC control. It's
difficult to reproduce and seems to happen infrequently, but the
captured stack trace points to wxLuaState::LuaPCall call. This is
running wxlua 2.8.12.2 and wxwidgets 2.9.5 (compiled at the end of
April).

I'm including the top part of the stack trace below (the full stack is
in this ticket:
https://github.com/pkulchenko/ZeroBraneStudio/issues/164), but there
are several odd things I noticed.

1. The trace shows lua51!lua_yield call after wxLuaState::LuaPCall
call, but I don't see any lua_yield calls in that function.

2. The trace shows wxProgressDialog_delete_function call in the stack,
but I don't use that component anywhere in the application; the stack
looks wrong at that point as I wouldn't expect any wxProgressDialog
call from lua_getinfo.

3. The crash seems to be in this fragment in wxlua/wxlcallb.cpp:

// Don't track the wxEvent since we don't own it and tracking it

I also asked in wx-user maillist, but it may be more wxlua related
than wxwidgets related. I'll post an update if I get any additional

Re: [wxlua-users] Strange (occasional) crash in wxLuaState::LuaPCall

2013-06-17 Thread Paul K

Hi John,

 lua_yield is a coroutine function, are you running coroutines? If so, then 
 Lua will be swapping lua_States in and out and pausing them whenever it wants 
 to, making the stack seem very strange.

I do (in general), but it's in a completely different part (for
debugging) and is not involved there; so, it's indeed puzzling.

 You're not trying to install event handlers in a coroutine are you? As we 
 discussed, that's always a bad idea.

No; this affects the applications that I debug, but not ZBS itself.
I'm careful not to even open new windows while in coroutines and all
events like this are delayed in the application until it's safe to do
(and is only done in the main thread).

 Did you ever create a wxProgressDialog? The Lua garbage collector may simply 
 be running and finally getting around to deleting it.

No; and that's another puzzling part. I don't use wxProgressDialog at
all. Not sure why it would be deleted...

 Can you rebuild in debug mode? The stack should have line numbers which will 
 clear things up.

That's a good suggestion; I prepared a debug build, but haven't heard
back from the user yet. BTW, the dll is 186M in debug more ;).

 Everything is normal up to LuaPCall, but then I presume you're running a 
 coroutine that's calling the lua_yield, and wxLua does use lua_getinfo for a 
 few things so that may be normal, but the lua_close is very wrong unless 
 you're closing a coroutine, perhaps the coroutine had a wxProgressDialog and 
 that's why it's getting deleted at this point? I can't imagine who's calling 
 AddPendingEvent though, are you?

I agree; everything looks normal up to that LuaPCall, but very
strange after that. I do have one AddPendingEvent call (and it's in
one of the branches for AddChar event, so it *can* be related), but
definitely not from wxProgressDialog destructor.

Thank you for confirming my suspicions. I'll see if I can get any
additional information from the debug build...

Paul.

Hi John,

 Can you add a new method GetContentScaleFactor that can be used to

 Sure, I can do that on Monday.

It would be great! I also noticed that we don't expose wxOverlay
(http://docs.wxwidgets.org/trunk/classwx_overlay.html). Can you add it
as well? It includes only a couple of methods and can be useful for
drawing on top of other controls, for example, over a minimap as
suggested here:

[wxlua-users] wxlua trunk build fails on Windows using Mingw

2013-07-19 Thread Paul K

Hi John,

I tried to compile the current trunk on Windows using mingw and ran
into a compilation error:

...wxLua/modules/wxbind/src/wxcore_bind.cpp: In member function
'virtual bool wxLuaBinding_wxcore::RegisterBinding(const
wxLuaState)':
...wxlua/wxLua/modules/wxbind/src/wxcore_bind.cpp:7495:46: error:

...wxLua/modules/wxbind/src/wxcore_bind.cpp:7496:46: error:
'wxEVT_COMMAND_FILEPICKER_CHANGED' was not declared in this scope

This follows a warning about re-definition:

...wxLua/modules/wxbind/src/wxcore_bind.cpp:73:0: warning:
wxEVT_COMMAND_DIRPICKER_CHANGED redefined [enabled by default]
...include/wx-2.9/wx/filepicker.h:418:0: note: this is the location of

...include/wx-2.9/wx/filepicker.h:417:0: note: this is the location of

The issue seems to be caused by this #if in modules/wxbind/src/wxcore_bind.cpp:

#if defined(__MINGW32__) || defined(__GNUWIN32__)
// FIX: internal compiler error: output_operand: invalid
expression as operand

I'm not sure if the comment still applies, but I removed this #if (and
another one around line 7488 in the same file) and compiled without
any errors/issues.

Can you please take a look at this and check if this #if is still
needed? It's seems like you can safely remove it. Thank you.

I'm using the latest wxwidgets (2.9.5 release candidate) and gcc 4.6.2.

[wxlua-users] Using wxlua with Lua 5.1 and Twoface ABI mapper

2013-07-19 Thread Paul K

Hi John,

I've been looking into using twoface ABI mapper
(http://corsix.github.io/twoface/) to run ZeroBrane Studio on top of
Lua 5.2 without recompiling wxlua and luasocket (both are compiled for
Lua 5.1). For those not familiar with it, it allows to run Lua 5.2
engine with modules compiled for Lua 5.1 without any changes to those
modules. In my case, I use it with ZBS that is compiled for Lua 5.1
and can make it run with Lua 5.2 by replacing lua51.dll with a
different one (and adding lua52.dll).

I have been able to run it with wxlua, but I ended up patching wxlua
in one place. For some reason when I ran it originally, I was getting
wxLua: wxEvtHandler::Connect() in wxLuaEventCallback::OnEvent(),
callback function is not a Lua function. messages in more or less
random places. This error comes from an event handler check in
wxlcallb.cpp and it appears to be only active for Lua 5.1:

#if LUA_VERSION_NUM  502
// lua_setfenv() is not in Lua 5.2 nor can you set an env for
a function anymore
wxlState.GetGlobals();
if (wxlState.lua_SetFenv(-2) != 0)
#endif // LUA_VERSION_NUM  502
{
// Don't track the wxEvent since we don't own it and tracking it
// causes clashes in the object registry table since many can be
// created and deleted and the mem address is resused by C++.
wxlState.wxluaT_PushUserDataType(event, event_wxl_type, false);
wxlState.LuaPCall(1, 0); // one input no returns
}
#if LUA_VERSION_NUM  502
else
wxlState.wxlua_Error(wxLua: wxEvtHandler::Connect() in
wxLuaEventCallback::OnEvent(), callback function is not a Lua
function.);
#endif // LUA_VERSION_NUM  502

I have never seen this error with 5.1 and am not sure what the purpose
of it is. Given that it doesn't even run for Lua 5.2, I completely
disabled this check and everything appears to be working as expected.

Is there any reason for this check (especially given that it behaves
differently for lua 5.1 and 5.2) and is it possible to remove/disable
it?

Paul.

Re: [wxlua-users] Using wxlua with Lua 5.1 and Twoface ABI mapper

2013-07-20 Thread Paul K

Hi John,

 Interesting, but that means that they're emulating the removed functions and 
 I wonder what their setfenv() does.

Right; the code for setfenv is here:
https://github.com/corsix/twoface/blob/master/twoface.c#L492-L532

 In 5.2 setfenv() function was removed and the environment for a function is 
 set by the _ENV table which should be the first upvalue for the function. I 
 believe that this is automatic so the 5.2 behavior should be more expected, 
 but I haven't rigorously tested what happens with callbacks in modules or 
 even if you swap out the _ENV before setting the callback.
 http://stackoverflow.com/questions/14290527/recreating-setfenv-in-lua-5-2

yes, I'm familiar with this logic (in fact, one of the answers is
mine), but only on the Lua side. I'm not sure how it maps to C calls.

 Is there any way to detect when the twoface DLL is being used so that the 
 code can take the 5.2 path?

Possibly, but I can't answer that question.

 Or maybe compile wxLua for 5.2 and use woface to treat 5.1 as 5.2 instead of 
 the other way around.

No, this won't work as Twoface only works one way (mapping 5.1 calls
to 5.2 engine).

For now I patched my build process to remove those fragments and so
far have been running with twoface and Lua 5.2 without issues. I'm
still not sure what that fragment I removed does as my event callbacks
use various upvalues and seem to work correctly without that setfenv
check (and they were throwing the error before I removed the checks),
which makes me think that the check is not really needed.

I'll leave the decision up to you and let you know if I run into any
issues, but so far I only have two patches that make my wxlua
libraries deviate from yours: this change (not deployed yet) and the
live coding fix I applied
(http://comments.gmane.org/gmane.comp.lib.wxwidgets.wxlua.user/3273).

Actually, there is one more interesting issue, related to the live
coding fix. I'll describe it briefly here, maybe you can add some
details to it.

The classes you create in wxlua conveniently allow additional
properties to be assigned to them. For example, I can do local editor
= wxstc.wxStyledTextCtrl(...) and then editor.foo = 'bar' and it
all works. However, if I then try to access editor.foo from *another*
coroutine, it doesn't see that property and I get wxLua: Unable to
call an unknown method ... error, even though the property is there.
I haven't been able to figure out where exactly it fails and for now I
just worked around these cases, but it would be great if this could be
fixed (if there is a fix for that).

Ideally, editor.foo should return nil and editor.foo() should return
an error, but the comment you have in the code seems to point out that
it may not be possible to distinguish between these two cases. I think
it's because in editor.foo(), it gets the value of editor.foo first
and then calls it as a function. I'll be fine if it returns `nil` and
then fails on the function call.

Paul.

Re: [wxlua-users] Crash on lua_close() [was: Using wxLua with Lua 5.0.2]

2013-08-09 Thread Paul K

Hi Andreas,

 So somebody who knows the internals of wxLua  wxWidgets should
 probably be able to find the problem pretty quickly. For me it's complicated
 because I hardly know anything about C++. I have 15+ years of experience in
 plain C but C++ still makes me shiver :) That's why it's very hard for me to
 find out what's actually going on here.

I'm in a similar situation. I'm sure John L reads the maillist, but he
may not be able to respond right away.

 Ok, maybe I'll try it with mingw but I can hardly believe that the problem
 is with Visual C...

I tend to agree, especially given that it still crashes for me in some
cases. You may want to re-compile using the latest trunk to see if it
makes it any better as I tend to work with the latest versions of
wxlua.

Paul.

Re: [wxlua-users] Difference between Lua and wxLua executable

2013-08-18 Thread Paul K

I'm very interested in what manifest needs to be used as well. My
executable *does* include a manifest, but it doesn't statically
compile wx.dll and loads it at run-time. My calendar looks like a
generic one (the one that Milind has on the left side), so I either
need to have a different content in the manifest or needs to include
in the DLL file itself.

It seems like the required addition to the manifest is quite simple
(as per
http://msdn.microsoft.com/en-us/library/windows/desktop/bb773175(v=vs.85).aspx):

dependency
dependentAssembly
assemblyIdentity
type=win32
name=Microsoft.Windows.Common-Controls
version=6.0.0.0
/
/dependentAssembly
/dependency

I added it to my executable, but the controls are still shown as generic ones.

I also removed this part of the manifest from wxlua and it indeed
turned the native controls into generic ones. It seems like this
is what is missing from the lua.exe file, but I'm not sure (yet) why
it's not working in my case...

Hummm, I do see the same differences you do and I get the same results
even when I compile it fresh using MSVC 2008 (the sourceforge packages were
built with MSVC 6).

I ran depends[1] on them and found that they all use the exact same DLLs
except for these differences :

They both use these two DLLS (note I built using 64-bit arch)

c:\windows\winsxs\amd64_microsoft.windows.common-controls_6595b64144ccf1df_6.0.9200.16579_none_418ab7ef718b27ef\COMCTL32.DLL

wx.dll also uses this which is older and that may explain the older
looking calendar control.

c:\windows\winsxs\x86_microsoft.windows.common-controls_6595b64144ccf1df_5.82.9200.16384_none_bf100cd445f4d954\COMCTL32.DLL

I believe it has something to do with the manifest file, lua.exe is not
compiled with one, but all the wxLua apps use the wxWidget manifest file.

http://msdn.microsoft.com/en-us/library/windows/desktop/bb773175%28v=vs.85%29.aspx

I suppose I could try building lua.exe using a similar manifest file and
see if that changes anything.

 SetDropTarget requires wxDropTarget object passed to it, but
 wx.wxDropTarget is an empty table and doesn't have new method to

After that wxlua and lua produce the same (calendar) results. You can
also tweak the manifest before embedding it to see the effect.

I don't know what you mean. What DLL is included with Windows that you ship?

Not sure; when I tried the same manifest with my wx.dll compiled with
mingw, I get side-by-side error:

Activation context generation failed for ...zbstudio.exe. Dependent
Assembly
Microsoft.Windows.Common-Controls,publicKeyToken=6595b64144ccf1df,type=win32,version=6.0.0.0
could not be found.

When I copy all the dlls from 2.8.12 and run with the same executable,
everything is fine. I'm not sure what dll I'm missing, but I thought
it was one of wxmsw28_*vc_custom.dll.

okay, I managed to get my application running with the right manifest

correct, but I was missing a proper way to reference the manifest.

It turned out that the way I included manifest was not correct as my
.rc file had 1 RT_MANIFEST zbstudio.manifest and it should have been
1 24 zbstudio.manifest. After I added the correct reference (and
included dependentAssembly reference) the manifest was recognized
and I could run my application using wxlua 2.8.12 DLLs and could see
the expected results.

I just added a resource and manifest file for wxLua's lua.exe, but it didn't
change how the calendar control looked.

Is there anything that you did differently?

Unfortunately, this doesn't really help me as I was hoping to
reference a DLL that is included with Windows, rather than ship mine,
but maybe this will help others...

I don't know what you mean. What DLL is included with Windows that you ship?

Re: [wxlua-users] How to accept drag and drop files on all platforms?

2013-08-25 Thread Paul K

Hi John,

 Sorry yes, I looked into this, but it does require a few more virtual 
 functions in
 wxFileDropTarget. I believe that it should be pretty easy.

Are you saying that it would be pretty easy for you to add them or
that it will be pretty easy after you add them ;). In any case, I'd
appreciate if you could add the missing functions and provided a
simple example I can use as a starting point. Thank you!

[wxlua-users] Can't call some wxKeyboardState methods on wxMouseEvent, but should

2013-09-08 Thread Paul K

Hi John,

I'm trying to call wx.wxMouseEvent():GetModifiers(), but get wxLua:
Unable to call an unknown method 'GetModifiers' on a 'wxMouseEvent'
type.

wxMouseEvent is inherited from wxKeyboardState (among other things),
so it should definitely work. In fact, I can call some methods (like
ControlDown() and CmdDown()) just fine, but none of the modifier
methods (GetModifiers(), HasModifiers(), HasAnyModifiers(), and so on)
work (http://docs.wxwidgets.org/trunk/classwx_keyboard_state.html).

I checked wxbind and indeed GetModifiers only shows up for wxKeyEvent
and nothing else. Can you please add it to wxMouseEvent as well? Thank
you.

Paul.

2013-09-11 Thread Paul K

Hi John,

 That function (and class hierarchy) only exists in wxWidgets 2.9 onwards. 
 It's just an alternative to the current ControlDown(), AltDown(), ShiftDown() 
 functions. Will those work for you in the near term?

Yes, but instead of checking event:GetModifiers() ==
wx.wxMOD_CONTROL I need to do event:ControlDown() and not
event:AltDown() and not event:ShiftDown() and not event:MetaDown() or
something along those lines.

Paul.

[wxlua-users] wxlua fails to build against LuaJIT 2.0.2

2013-09-11 Thread Paul K

Hi John,

I'm trying to build wxlua against LuaJIT and get compilation errors. I
know, I can build against normal Lua 5.1 and use it with LuaJIT (and
that's exactly what I'm doing now), but I'd like to avoid that extra
step if possible. These are the errors:

../wxLua/modules/wxlua/lbitlib.c:83: error: expected ‘=’, ‘,’, ‘;’,
‘asm’ or ‘__attribute__’ before ‘lua_Unsigned’
more errors here
../wxLua/modules/wxlua/lbitlib.c:348: error: too many arguments to
function ‘lua_pushunsigned’
make[2]: *** [modules/luamodule/CMakeFiles/wxLuaModule.dir/__/wxlua/lbitlib.c.o]
Error 1
make[2]: *** Waiting for unfinished jobs
make[1]: *** [modules/luamodule/CMakeFiles/wxLuaModule.dir/all] Error 2
make: *** [all] Error 2
Error: failed to build wxLua

Is it something that can be addressed? It would also be great if wxlua
would only load its own bitlib into bit table if it's not already
loaded.

Paul.

 since CMake advertises that CMAKE_INSTALL_PREFIX is the install dir I went

yes, replacing BUILD_INSTALL_PREFIX with CMAKE_INSTALL_PREFIX worked. Thank you.

Re: [wxlua-users] wxWindows 3.0.0, wxLua 2.8.12.3 and OS X?

2013-11-16 Thread Paul K

Hi Kent,

I just compiled my wxlua based application with wxwidgets 3.0 couple
of days ago and haven't seen any issues/crashes yet. I'll try to run
the samples tomorrow (don't have access to my MacBook right now) to
check if there are any issues with them.

 - Is this setup supposed to work at all, i.e. wxLua with wxWindows 3?

I'd say so. I've been using wxwidgets 2.9.5 for several months and
have compiled/run wxwidgets 3.0 (including different pre-release
versions) without issues.

 How do I run the samples on OS X? I don't have a wxLua exe, but a
  wxLua.app. I tried open -a wxLua bindings.wx.lua when this
  still did not crash, but the sample program argument seemed to be
   ignored.

You should be able to pass parameters after --args, so it should probably be:

open -a wxLua --args bindings.wx.lua

You should also be able to use a normal lua interpreter and
libwx.dylib (or whatever the default name for wxlua library is).

 I'm a bit puzzled how to run the samples, but for some minutes doing

 My questions are

  - Is this setup supposed to work at all, i.e. wxLua with wxWindows 3?

Hi Lucas,

 I wonder if there is any debugger done in wx.lua that have function Step In
 Step out.Tenho wxLua on a project at my college (UFOP) in Brazil and need such
 a function to be used in my code.

Yes, there is an example in samples/editor.wx.lua, which implements
step-in and step-out commands.

I have also developed an IDE roughly based on that example, which
implemented that functionality using MobDebug (instead of the debugger
components that come with wxlua); more details here:

Is it my local setup or is it something that needs to be fixed in

Just a quick update on this. I tried compiling using mingw-tdm using

Re: [wxlua-users] How to provide wxApp::MacNewFile, wxApp::MacOpenFiles, and wxApp:MacReopenApp methods?

2014-01-22 Thread Paul K

Hi John,

 I'm looking for a way to provide MacNewFile, MacOpenFiles, and
 MacReopenApp methods
 (http://docs.wxwidgets.org/trunk/classwx_app.html), but can't figure
 out how to do this in wxlua and don't see this in any of the examples.

Can these methods be used with the current version of wxlua or do they
need to be added first?

I also asked about some other things earlier: wxRegKey, CallAfter
(http://wxwidgets.blogspot.com/2013/01/about-benefits-of-procrastination.html)
and wxSTC:GetLibraryVersionInfo calls. wxRegKey is a low priority for
me as I'll probably be using winapi that provides the same
functionality.

Paul.

 I have started to update wxLua for wxWidgets 3.0 without WX_COMPATIBILITY_2_8

Great; thank you.

 Note that wxLua builds ok with compat 28 defined in wx30.

Right; this is exactly how I compiled it and it's working fine for me.

This is using the latest trunk of wxlua and wxwidgets (compiling on Linux).

Re: [wxlua-users] Compilation errors without compat28 setting with the trunk version

2014-02-07 Thread Paul K

Hi John,

 Yes, there are far more differences than I realized, you'll have to use 
 --enable-compat28 for the near future.

That's okay; I already added it to some of my build scripts, just
wanted to let you know.

 I have also seen some problems with the wxLua app (editor.wx.lua) not exiting 
 for some reason with 3.0, but not 2.9.x if I remember correctly.

I have seen this in my application as well, even with 2.9.5. I'd like
to get to the bottom of it, but so far I've been using os.exit() at
the end of my main script. For some reason, each of the platforms is
guilty in some way:

-- (1) to fix a crash on OSX when closing with debugging in progress.
-- (2) to fix a crash on Linux 32/64bit during GC cleanup in wxlua
-- after an external process has been started from the IDE.
-- (3) to fix exit on Windows when started as bin\lua src\main.lua.

I just tested the last one using 2.9.5; if I don't have os.exit() at
the end, the script just hangs. Not sure why... In cases 1 and 2, I do
call :Detach() on the started process, but it still crashes after
MainLoop is done without os.exit().

Paul.

 I am also thinking that the switch to 3.0 without compat28 will probably
 pose problems for people since Lua won't give compile time errors for
 missing/changed functions. It might not be too hard to make some sort of
 diff file using the code from bindings.wx.lua to print the full list of
 functions for each version.

[wxlua-users] How to make invalid UTF-8 data to appear in wxSTC in Unicode builds?

2014-02-18 Thread Paul K

Hi John,

I'm looking for a way to handle (possibly) invalid UTF-8 characters
and seem to be missing wxString::From8BitData() and
wxString::To8BitData() methods (according to this page:
http://docs.wxwidgets.org/trunk/overview_unicode.html#overview_unicode_supportout).

What I am trying to do is to load a file into wxSTC (Scintilla
component). I know that Scintilla can deal with invalid UTF-8
characters as SciTE displays them as nice inverted rounded boxes with
hex codes inside, but I can't get the same effect with wxSTC. If I try
to load UTF-8 file with characters in, for example, 1252 encoding, the
content fails to load into wxSTC (it shows as empty).

You can see this effect by running editor.wx.lua example. Just try to
load a file that has \232 or \226 character and the content is going
to be empty.

What's interesting is that the content is loaded from a file just
fine, so it seems like at least that part is handled correctly, but
the text is not loaded into wxSTC until I find and fix invalid UTF-8
characters (I use SetText method, but I've tried others with the same
result). I thought that using From8BitData() may help me to pass all
those characters intact to Scintilla, which will be able to display
them, but I can't test as From8BitData() is not exposed in wxlua.

I'm open to other ideas to make it work...

Paul.

Re: [wxlua-users] How to make invalid UTF-8 data to appear in wxSTC in Unicode builds?

2014-02-18 Thread Paul K

Hi John,

 I'm no expert in UTF8, but isn't it possible that a malformed UTF8 sequence 
 makes the rest of the file unusable in the sense that you can't really be 
 sure how many bytes the 'bad' sequence is so you could be off by a few bytes 
 for the rest of the file?

Not really, as you can simply skip all invalied 8-bit characters
(which is what I do to fix invalid sequences). Scintilla does better
as it can display them as well.

 From8BitData() is now in SVN trunk. I'm not sure that it will help as it uses 
 the wxConvISO8859_1 converter, but it is different than the normal wxConvUTF8 
 converted used normally.

Do we also get To8BitData(), as I may need it to save the data back to a file?

I'll compile and give it a test some time tomorrow... Thank you!

Paul.

Re: [wxlua-users] How to make invalid UTF-8 data to appear in wxSTC in Unicode builds?

2014-02-21 Thread Paul K

Hi John,

 Yes, note that From8BitData() is static and To8BitData() is not.

Thank you for the prompt change! Unfortunately, it didn't have the
desired effect for me; maybe I misread wxwidgets documentation.

Let's say I have three invalid UTF-8 characters: string.char(0x80,
0x81, 0x82). If I assigned them to a variable u, it has proper length
(#u == 3). If I try to add them to wxSTC, nothing happens (the length
of the content doesn't change).

If I use From8BitData(), then I get 6 bytes instead of 3:
#wx.wxString.From8BitData(string.char(0x80, 0x81, 0x82)) == 6, but
this looks like fixed UTF-8 code. When I add the result to wxSTC, I
do get 6 bytes of content there, but that's not what I expected: I
expected three characters displayed with 0x80, 0x81, and 0x82 as their
codes.

What am I doing wrong?

Paul.

Re: [wxlua-users] How to make invalid UTF-8 data to appear in wxSTC in Unicode builds?

2014-04-02 Thread Paul K

Hi John,

 I honestly don't know. Did you try to call wxSTC::AddTextRaw(const char*)? 
 This function does not do any UTF8 conversions before passing the string to 
 Scintilla.

It worked! I wasn't aware of *TextRaw methods and they do exactly
what's needed in this case. The only issue is that you don't provide
GetTextRaw, so I can show the file, but can't save proper results (as
they get mangled into a fixed UTF-8 when I use GetText()).

I only see AddTextRaw and InsertTextRaw in wxlua; there seems to be
GetTextRaw, SetTextRaw, AppendTextRaw, and GetSelectedTextRaw missing
from wxlua. Would it be possible to add them? Thank you!

Hi John,

 The latest wxwidgets (3.1) includes updated Scintilla component
 (3.3.9), which appears to no longer have
 wxSTC_COFFEESCRIPT_HASHQUOTEDSTRING.

This is still happening. It would be good to fix this in wxlua as it
doesn't compile with the latest wxwidgets code. Thank you.

Paul.

 Hi John,

 I tried to compile the latest wxlua with the latest wxwidgets and ran

 Could you please remove the reference from the binding? I was able to
 compile successfully after commenting it out. Thank you.

 Paul.

Re: [wxlua-users] Build issue with wxGTK 3.0.1

2014-06-23 Thread Paul K

John,

 Fixed now in svn, at least for my version of gcc, Fedora 20, gcc 4.8.2.

Thank you for the update. Curious, can you run a simple script that
checks if GetChildren() is available method for wxWindow? It's been
reported that for some reason GetChildren() is not available when
compiled with wxgtk3 (3.0.1) on Archlinux:

wxLua: Unable to call an unknown method 'GetChildren' on a 'wxWindow' type.
stack traceback:
[C]: in function '__index'
...

I haven't had a chance to test it myself yet, but I can use it when
compiled on Windows and it was clearly present in previous versions as
well (2.9.x).

Paul.

 Thanks a lot John,
 it builds now.
 I'll prepare a buildscript for SVN so my fellow Arch users can
 comfortably build and use wxLua with wxgtk 3.


 That sounds great, what else is needed to build on Arch?


 For the sake of completeness, here are the warnings I get.


 Yeah, I've been lazy about those unused strings, they would be awkward to
 #ifdef off. Fixed now in svn, at least for my version of gcc, Fedora 20, gcc
 4.8.2.

 Regards,
 John

[wxlua-users] wxDir is missing Close method

2014-07-04 Thread Paul K

Hi John,

I just noticed that wxDir is missing Close method for some reason.
This creates a problem with those situations when the directory
content needs to be enumerated with FindFirst and FindNext and aborted
without finishing (as the object seems to keep some of the files in
locked state internally).

Would it be possible to add the missing method? Thank you.

Paul.
