nobody seems to be able to find a newer version -- hard to understand.

I have just installed a new (and very easy) Ubuntu-eee distro and then installed
WxLua for Linux without any problem at all. So now I'm up and running with WxLua
on my 'toy' PC. That's both a good and lazy solution :-)

Thanks,
Kyle

yes, a bit old...

right. THis is because AFAIK the kernel uses libc, too.

Doesn't newer versions of Xandros provide newer libc versions?

BTW in any case a good solution is simply to get the sources of wxLua, install 
wxWidgets -dev packages and then compile wxLua yourself. It will require you 
more time but this is surely going to work...

HTH,

Here's the message I get from the wxLua installer package:

"Error: Your copy of glibc, a core system library, is too old for this package.
You need at least the following symbols in glibc: GLIBC_2.4."

I believe what's on my machine now is glibc 2.3. I found a post on some forum,
complaining that Debian (or maybe just Xandros) has an old glibc (2.3, I think)
but there was no suggestion of what to do about that. Apparently, you can't 
just copy glibc from one linux to another and expect it to work.

Thanks for asking. I guess lots of eee pc users install Ubuntu or other distro
in order to get things to work, that won't install on Xandros.

what's the error message? Which version of glibc do you use?

What are the errors and messages in config.log? Are you trying to
build both wxWidgets and wxLua or using a prepackaged wxWidgets?

You can also try to use the Makefiles (not running configure) in the
wxLua/apps/XXX/src dirs. You must have the 'wx-config' script that
comes with wxWidgets in your path for them to work.

Glad you like it.

It works great on Ubuntu and their derivatives. I can't speak for Xandros.

I currently do wxLua development work on a Windows box, but would like to do
wxLua scripting on my eee pc, which comes with Xandros linux (a debian variant).
Has anyone been able to install wxLua on Xandros, or for that matter, on any
Debian linux? It almost installs when I run the install script, but then gives
up because the debian distro of glibc is such an old version. Is there any
workaround for this sort of thing? This is basically what keeps me from doing
more linux development work, so I would really like to solve this problem.

Anyhow, I've been living and breathing Lua and wxLua for a few months now and
it's very nutritious, nutty, and full of chewy goodness.

Thanks,

wxLua does not compile properly under Fedora core 8 (fc8)

Reason: fc8 packages (lua and lua-devel) creates lua.h (etc) and not
lua5.1.h

Fix steps
(1) Change lua5.1 to lua in configure
(2) Change llua5.1 to llua in modules/Makefile.in and apps/Makefile.in

The reason I list this as a bug is that it should not be necessary to do
(2).  Please add a variable that can be changed in exactly one place in the
configure script.  It would be good to have an option to configure.

FYI, to run under fc8 with ./configure --prefix=/usr/local, require
export LD_LIBRARY_PATH=/usr/local/lib
export LUA_CPATH="/usr/local/lib/lua/5.1/?.so"

I have managed to get it working, by adding this function:


function DoFindMatchingBracePosition(editor)
	local length = editor.Length;
	if (length == 0) then
		return -1,-1
	end
	local pos = editor.CurrentPos;
	if (pos > 0) and (editor:PositionBefore(pos)==(pos-1)) then
		local prevc = editor:GetCharAt(pos-1);
		if (prevc == 91) or (prevc == 93) or (prevc == 123)
		or (prevc == 125) or (prevc == 40) or (prevc == 41) then
			return pos-1, editor:BraceMatch(pos-1);
		end
	end
	if (pos < length) and (editor:PositionAfter(pos)==(pos+1)) then
		local nextc = editor:GetCharAt(pos);
		if (nextc == 91) or (nextc == 93) or (nextc == 123)
		or (nextc == 125) or (nextc == 40) or (nextc == 41) then
			return pos, editor:BraceMatch(pos);
		end
	end
	return -1,-1
end


...and modifying the UPDATE_UI event handler to this:


editor:Connect(wxstc.wxEVT_STC_UPDATEUI,
	function (event)
		UpdateStatusText(editor)
		local braceAtCaret,braceOpposite = DoFindMatchingBracePosition(editor)
		if (braceAtCaret > -1) and (braceOpposite == -1) then
			editor:BraceBadLight(braceAtCaret)
			editor:SetHighlightGuide(0)
		else
			editor:BraceHighlight(braceAtCaret, braceOpposite)
		end
	end)


Thanks again for your help.

Thanks John. I'll see how I get on with this and will report back if I
succeed. It seems odd that code block folding is easy to add in but
not this, but that's a quirk of how wxStyedTextCtrl works rather than
anything wxLua is responsible for I expect.

The wxLuaEditor does it on the C++ side, but perhaps it can be
translated to Lua.

See:

http://wxcode.cvs.sourceforge.net/wxcode/wxCode/components/wxstedit/src/stedit.cpp?view=markup

  156     EVT_STC_UPDATEUI         (wxID_ANY, wxSTEditor::OnSTCUpdateUI)

  340 void wxSTEditor::OnSTCUpdateUI(wxStyledTextEvent &event)

 1874 void wxSTEditor::DoBraceMatch()

and

wxlua.sf.net is the continuation of wxLua and you can download the
newest version there.

I don't believe that LuaScript (wxLua?) ever supported WSH (Windows
Scripting Host?). I think LuaScript was merely a name implying that
wxLua was C++ wxWidgets using a script type language, Lua. Unless
there was a separate LuaScript program that I am not aware of.

Hi List,

Could anyone help me with getting brace matching to work (i.e. when
the text cursor is over a brace, highlight both the brace and its
matching twin blue, unless the brace is mismatched, in which case
highlight it red) for a wxStyledTextCtrl control? It seems like it
should be obvious, but I can't seem to find this information anywhere.
What change(s) would you make to the editor.wx.lua sample script to do
this? (I know that it must be possible since wxLuaEditor supports it.)

Thank you,

-Duncan
