Re: AW: can I lock screen over more than one handler?

[Jonathan Lynch via use-livecode]

I have a suggestion, if nothing else works. Use two players, layered on top of 
each other. When you switch the source of a player, do it to the player on the 
bottom, then move it to be on top of the other player. 

By switching back and forth, and only reassigning the player on the bottom, it 
should always cover the transition.

Re: AW: can I lock screen over more than one handler?

[Jonathan Lynch via use-livecode]

I have found that lock screen only blocks screen updates within the main LC 
context.

So, for example, it does not block whatever is happening in a browser.

For some reason, it also sometimes seems smoother to call a function rather 
than a handler, but perhaps I misperceived what was happening.

Re: can I lock screen over more than one handler?

[Jonathan Lynch via use-livecode]

Hi Tiemo,

It unlocks at the end of a handler. This can be a problem when calling another 
handler.

I handle it by turning a called handler into a function. However, I don't think 
you can do it with a "send in time" handler.

Re: debugging a CEF browser instance

[Jonathan Lynch via use-livecode]

Hi Bernard,

I work with JS in the browser widget quite a bit.

I have just gotten used to testing JS commands very carefully, step by step, 
because it does not really provide any debugging information.

It would be nice to have that.

Okay. - I got it submitted :)

I had revoked an older certificate to make sure I was using the right one, but 
that certificate was still in the key chain. 

Fingers crossed they like it on the first try.

Sorry for my hidden curse word there - it was just one of those moments.

Re: Submitting to the #%^%#? App Store

I created a new profile just for this - still get the same error.

After that I tried manually codesigning, but then I got the same error again.

Any other ideas? And thanks for taking the time on this - it is much

Re: Submitting to the #%^%#? App Store

Hi Colin,

Yes and yes 

Do we need to sign the actual file after it is created? I thought that happened 
when we created to executable from LC.

Submitting to the #%^%#? App Store

[Jonathan Lynch via use-livecode]

Both venting and seeking advice.

Actually submitting an app to iTunes Connect is not easy, to put it mildly.

I am getting an error...

The executable 'Payload/Augmented Earth.app/Augmented Earth' must be signed 
with the certificate that is contained in the provisioning profile.

I have no idea how it could be wrong. The distribution provisioning profile 
seems correct to me. Is there a step I am missing? I thought I was following 
the steps outlined on the LC site.

Re: Advice on copying and pasting in mobile

[Jonathan Lynch via use-livecode]

Hi Hermann,

It turns out we can have a div with editable content in html5.

For version 1.1 or 1.2, I might figure out how to make a full content form in 
HTML, including an editable div, which accepts both text and images.

For now, I created a special input in HTML5 to allow pasting into the content 
field. It is a little weird to go into a special mode just to paste, but this 
will work in both iOS and Android.

Re: Advice on copying and pasting in mobile

[Jonathan Lynch via use-livecode]

I have been thinking a lot about that...

I like having the ability to have images inside a field in LC, something that 
both HTML and native fields do not do readily.

A user can enter text, add a picture, and enter more text. It is simple and 
intuitive this way.

That said, with an HTML form I could have a lot more stuff - but I do not know 
if more is better for this.

Honestly, I think I am feeling some pedantic peevishness over not being able 
access the clipboard, and that is coloring my judgment.

I am pretty sure I could grab an existing iOS external, edit it to add in copy 
and paste functions from Xcode, and use that. I have done something similar, 
with a different functionality, in the past.

That would not help with android, though. An HTML solution would work fine with 
android.

Advice on copying and pasting in mobile

[Jonathan Lynch via use-livecode]

Hello,

I really need to be able to paste text in an LC field on mobile.

I can do it for iOS with the sunny text to speech external, but that external 
has an audio message that comes on when the app first opens, which would be 
rather confusing for users.

I have so far avoided LC builder because I felt I needed better documentation 
to learn it in the limited free time that I have. It seems like LC has provided 
some more tutorials now.

Here are my questions:

1. Can a widget (or library file) give us access to the clipboard on mobile 
devices? 

2. Are there any other existing externals that can do this?

My app is almost ready to submit, but it feels like the user should be able to 
paste content directly into the content field, which for other reasons cannot 
be a native field.

Thank you

Re: Google Static Maps Problem

[Jonathan Lynch via use-livecode]

Hi Bill,

I am looking at your stack now. I don't see any place where you use JavaScript 
to get get the bounds from the Google maps API.

I think you would have to do it that way to get a reliable result.

That won't give you corners, exactly, but it will give you a minimum bounding 
rectangle that contains your map.

Re: Google Static Maps Problem

[Jonathan Lynch via use-livecode]

The google maps API has a function for getting the bounds of a map, which 
adjusts at each level.

So, this is just a matter of calling on that function every time, so you get 
current bounds.

I will look at the stack later today.

Just be careful with bounds. They can cause confusion with changes in the 
orientation of the map.

Re: Printing a Widget Browser

[Jonathan Lynch via use-livecode]

Could you export to a file, launch that in the user's standard browser, and 
print from there?

Disallowing overscroll/bounce in the browser widget on iOS

[Jonathan Lynch via use-livecode]

Has anyone managed to block that annoying bounce effect? It looks terrible in 
an app.

I tried all sorts of CSS and JS, but no luck. I am going to explore editing the 
plist, since this is related to a UIWebView setting, but if anyone has already 
done this, it would be most helpful.

Are you saying the down scroll has less momentum?

I have no idea why it would do that, but you can increase the momentum overall 
by changing tRemainingDistance/15 to a lower divisor, like 
tRemainingDistance/10.

Re: Momentum Scrolling Script

Thanks Scott

I also found something else. Mousedown stops the momentum scroll, but then one 
must lift up the finger and start again to do more scrolling.

That should be fixable, though.

Re: Momentum Scrolling Script

[Jonathan Lynch via use-livecode]

I just realized I had the wrong way of checking to see if scrolling should
stop. Somehow it still worked, which is kinda weird. Here is the revised
script, with checking for tCount < 1 rather than tCount > 50

-

Momentum Scrolling Code


Local StartDrag

Local AllowDrag

Local StartDragMil

Local CumulativeMomentum


on mousedown

   focus on nothing

   if word 1 of the name of the target = "button" or the isbutton of the
target = 1 then

  exit mousedown

   end if

   put (the mouseV)+(the vScroll of me) into AllowDrag

   put the milliseconds into StartDragMil

   put (the mouseV) into StartDrag

   repeat with CM = 1 to 5

  put 0 into CumulativeMomentum[CM]

   end repeat

   send momentumAccumulate to me in 0 milliseconds

end mousedown


on momentumAccumulate

   if mouse(1) <> "down" then

  exit momentumAccumulate

   end if



   put the milliseconds-StartDragMil into tTimeForLastMove

   put (the mouseV) into tCurrentMouseV

   put tCurrentMouseV - StartDrag into tLastDistanceCovered



   if tTimeForLastMove = 0 then

  put 1 into tTimeForLastMove

   end if

   repeat with CM = 5 down to 2

  put CumulativeMomentum[CM-1] into CumulativeMomentum[CM]

   end repeat

   put (tLastDistanceCovered*10) / tTimeForLastMove into
CumulativeMomentum[1]

   put tCurrentMouseV into StartDrag

   put the milliseconds into StartDragMil

   send momentumAccumulate to me in 5 milliseconds

end momentumAccumulate


on mousemove

   if AllowDrag <> empty then

  set the vScroll of me to AllowDrag-(the mouseV)

   end if

end mousemove


on mouseup

   put empty into AllowDrag

   put 0 into tCMTotal

   Repeat with CM = 1 to 5

  add CumulativeMomentum[CM] to tCMTotal

   end Repeat

   put tCMTotal/5 into tAverageMomentum

   put tAverageMomentum * 30 into tRemainingDistance

   doMomentumScrolling tRemainingDistance,50

end mouseup


on doMomentumScrolling tRemainingDistance, tCount

   if tCount < 1 then

  exit doMomentumScrolling

   end if

   if mouse(1) is "down" then

  exit doMomentumScrolling

   end if

   put tRemainingDistance/15 into tDistanceToMove

   put the vScroll of me into tVScroll

   set the vScroll of me to tVScroll - tDistanceToMove

   put tRemainingDistance-tDistanceToMove into tRemainingDistance

   put tCount-1 into tCount

   send "doMomentumScrolling tRemainingDistance, tCount" to me in 5
milliseconds

end doMomentumScrolling

Momentum Scrolling Script

[Jonathan Lynch via use-livecode]

Hi everyone,

I just created and tested a momentum scrolling script on my iPhone, and it
appears to work quite well, so I thought I would share it here. It also
works on desktop with mouse dragging. If you see improvements, please share
them.

1. Make sure to have accelerated rendering on for the stack.
2. Make sure to set the layer mode of the group to "scrolling" for mobile
devices, so it will be fully responsive to the touch.
3. You can adjust the various constants in this script to alter the
duration, speed, and length of momentum scrolling. Just play with it as
needed.

Here is the script:
---


Local StartDrag

Local AllowDrag

Local StartDragMil

Local CumulativeMomentum


on mousedown

   focus on nothing

   if word 1 of the name of the target = "button" or the isbutton of the
target = 1 then

  exit mousedown

   end if

   put (the mouseV)+(the vScroll of me) into AllowDrag

   put the milliseconds into StartDragMil

   put (the mouseV) into StartDrag

   repeat with CM = 1 to 5

  put 0 into CumulativeMomentum[CM]

   end repeat

   send momentumAccumulate to me in 0 milliseconds

end mousedown


on momentumAccumulate

   if mouse(1) <> "down" then

  exit momentumAccumulate

   end if



   put the milliseconds-StartDragMil into tTimeForLastMove

   put (the mouseV) into tCurrentMouseV

   put tCurrentMouseV - StartDrag into tLastDistanceCovered



   if tTimeForLastMove = 0 then

  put 1 into tTimeForLastMove

   end if

   repeat with CM = 5 down to 2

  put CumulativeMomentum[CM-1] into CumulativeMomentum[CM]

   end repeat

   put (tLastDistanceCovered*10) / tTimeForLastMove into
CumulativeMomentum[1]

   put tCurrentMouseV into StartDrag

   put the milliseconds into StartDragMil

   send momentumAccumulate to me in 5 milliseconds

end momentumAccumulate


on mousemove

   if AllowDrag <> empty then

  set the vScroll of me to AllowDrag-(the mouseV)

   end if

end mousemove


on mouseup

   put empty into AllowDrag

   put 0 into tCMTotal

   Repeat with CM = 1 to 5

  add CumulativeMomentum[CM] to tCMTotal

   end Repeat

   put tCMTotal/5 into tAverageMomentum

   put tAverageMomentum * 30 into tRemainingDistance

   doMomentumScrolling tRemainingDistance,50

end mouseup


on doMomentumScrolling tRemainingDistance, tCount

   if tCount > 50 then

  exit doMomentumScrolling

   end if

   if mouse(1) is "down" then

  exit doMomentumScrolling

   end if

   put tRemainingDistance/15 into tDistanceToMove

   put the vScroll of me into tVScroll

   set the vScroll of me to tVScroll - tDistanceToMove

   put tRemainingDistance-tDistanceToMove into tRemainingDistance

   put tCount-1 into tCount

   send "doMomentumScrolling tRemainingDistance, tCount" to me in 5
milliseconds

end doMomentumScrolling

Re: How do we access the clipboard on mobile devices?

[Jonathan Lynch via use-livecode]

>From a design perspective, for being able to use paste, speech to text, and 
>emojis, I have Idea that comes from something Richard said.

When a user clicks on a field to edit, that field could appear to start from 
its location and grow to take up most of the screen.

It would actually be a mobile native field that is created on the fly. 

Then the user could use native field capabilities and it would look like it was 
designed that way on purpose.

When they click a 'done' button, it would shrink down to regular size, process 
the contents, and put them into the LC field.

If done right, that could be pretty sharp and would address the issue of fields 
being in scrolling groups - something I don't think we can do with native 
mobile fields.

Re: How do we access the clipboard on mobile devices?

[Jonathan Lynch via use-livecode]

Thanks Roger,

With the huge amount of LC/HTML work I have done over the last year, I feel 
comfortable in saying that LC is vastly superior for all of the underlying text 
processing and data manipulation that has to be done.

HTML/JS is all about presentation, but would be hard to use for the back end 
stuff.  

To be honest, I do wish LC had all of the basic modern interface options one 
normally expects for mobile devices, but I realize how expensive it is to make 
those things.

I am not trying to start a fuss - just find solutions for my particular problem.

This is what worked for me for this situation.

For situations where LC provides a full solution, it is MUCH faster to code in.

Re: How do we access the clipboard on mobile devices?

[Jonathan Lynch via use-livecode]

I just modified the texting part of Augmented Earth to use a browser widget for 
texting - it was a huge pain. But - now it has inertial scrolling, copy and 
paste, and works fine with all of the emojis.

I might wind up going that route on other text entry stuff. It is clean and 
smooth that way.

Re: How do we access the clipboard on mobile devices?

[Jonathan Lynch via use-livecode]

For this case, though, it will have to be called up specially, not made to look 
like it was already there.

The field in question also allows users to put in images - something I don't 
think native fields can do. So the app would have an enter text button that 
calls up the native field, where the user can type or paste text that is then 
inserted into the LC field.

Re: How do we access the clipboard on mobile devices?

[Jonathan Lynch via use-livecode]

Thanks Richard,

This conversation has made me realize I am about to have a yak shaving
moment...

The most important field for submitting a report in Augmented Earth is the
Content field. Because it is an LC field, I use it to allow the user to
enter text, format the text, and upload images. The images are a single
character with the image source set to an image, which is stored in a
hidden group.

It works quite well. The fields and images are combined to produce HTML
text. When a user reads a report, the various data and images are
downloaded and stored in their appropriate place. What they view is the
HTML that is auto generated from those fields and images and presented
through a widget.

I don't think a native field will allow me to insert images in the field in
the same way. And, of course, the content field is the place where a user
would most need to paste in text.

So, I could use native fields for entering text, but not with images
inserted in the text. Or, I can use an LC field for doing both, but then we
cannot paste.

Assuming I am able to submit the app to the App Store as it is, it seems
like I am going to have to come up with a way to paste text into an LC
field on a mobile device for version 1.1

That sounds very difficult. Would LC Builder allow me to do this? I am
pretty sure I could make an external in iOS that allows this - I have
written an iOS external in the past - but it was a big pain and LC Builder
seems like the way to do things like this in the future.

work, work, work

I appreciate your suggestion though. As long as I can generate native
fields inside of a group so they can be scrolled, I will explore that
method for all of the other fields.

Re: How do we access the clipboard on mobile devices?

[Jonathan Lynch via use-livecode]

I really want to have the same forms for every platform, not have to generate 
40 different fields on the fly and manage all of that.

I might try converting my forms into HTML forms and using the browser widget. I 
hate that because I invested so much time into the forms I have created, but 
not being able to paste text on a tablet kinda stinks.

I was very surprised it wasn't. I plan to submit Augmented Earth to the apple

text into their reports on a mobile device.

I think I will try to find a workaround between version 1 and version 1.1

No need to loop.

Set three flags to false. After each callback comes in and the flag gets

Re: HTML5 deployment: progress comes into sight

[Jonathan Lynch via use-livecode]

A callback is not synchronous, his point was that it would be nice to 
communicate synchronously between LC and JS, rather than use complex callback 
chains.

I agree with him, but I don't think there is a universal way to do that, just 
because some things in JavaScript, like rendering an image or using a 
webworker, are inherently asynchronous.

Re: Using callbacks within LC and JS

Yah - setting up threads that include JS event listeners was a big pain for 
Augmented Earth - I have no suggestions for simplifying that part.

That bit of complexity seems unavoidable to me.

Would it be possible to create a widget that links to an Inkscape library that 
processes svg data and sends it back to the widget to be displayed the way PNG 
is displayed?

Using callbacks within LC and JS

[Jonathan Lynch via use-livecode]

This is in response to a different thread, but worth discussing on its own.

I just wanted to explain my view on why callbacks are not as horrible as they 
seem at first, if one structures the script logically.

The below code explains:

On LCcontrolScript pcommand,pdata

If pcommand = empty then
Put "step1();" into tJS
Do tJS in widget "my browser"

Else if pcommand = "return from step 1" then
-- process pdata 
Put "step2();" into tJS
Do tJS in widget "my browser"

Else if pcommand = "return from step 2" then
--process pdata 
Put "step3();" into tJS
Do tJS in widget "my browser

Else if pcommand = "return from step 3" then
--process pdata 
--Finish doing whatever it needs and enjoy a great JavaScript display
End if

End LCcontrolScript

On the JS side, the different functions use 
"liveCode.LCcontrolScript(tcommand,tdata);" to return the output.

As long as we structure our callback thread logically, doing a bunch of 
callbacks between LC and JS is not so bad.

The same structure can be used by functions initiated in JS. 

Having done some messy callbacks, I have learned my lesson on this.

Re: HTML5 deployment: progress comes into sight

A native svg object that accurately displays all svg files is essential. I 
strongly support Mark's point on that issue. This is not reinventing the wheel 
- it's attaching the already invented wheel to the wagon.

Apparently, mobile phone compasses do not work well

[Jonathan Lynch via use-livecode]

After a bit of experimentation with different devices, and researching online, 
I have come to realize that the device simply cannot consistently detect one's 
bearing with accuracy.

I am going to mimic the way Pokémon Go lets the user spin the view around at 
will, but still auto adjusts the position as the user walks.

Just something to bear in mind for anyone else developing augmented reality 
apps.

Re: Does MobileSensorReading work?

If it helps anyone - one can apparently recalibrate the compass by facing 
north, stopping sensor tracking, and restarting sensor tracking. It is only a 
temporary solution.

Re: Does MobileSensorReading work?

[Jonathan Lynch via use-livecode]

The mobile sensor reading is having a problem when combined with the plist hack.

When I hit the home button to put the app in pause mode, and then go back into 
the app, the device thinks that north is in whichever direction the phone is 
facing when the app resumes.

It is strange.

Re: Does MobileSensorReading work?

Never mind - I see

It works after you turn on mobileSensorStartTracking, and appears to return an 
array on my device

Does MobileSensorReading work?

[Jonathan Lynch via use-livecode]

I put a button on my app and put the app on my iPhone.

The button had the following script:


on mouseUp

put MobileSensorReading("location",true) into tReading

answer the Keys of tReading

answer tReading

end mouseUp

I figured this would tell me if the function was supposed to return an
array or a variable, since I had read both online.

Interestingly, it returned empty for both.

Re: Apparent peculiar behavior in browser widget on iOS

[Jonathan Lynch via use-livecode]

More specifically - this seems to happen after setting the htmltext by script. 

It works fine if the browser widget already has the right htmltext when the 
stack loads.

Apparent peculiar behavior in browser widget on iOS

[Jonathan Lynch via use-livecode]

It appears that one cannot send a JavaScript message from the browser widget to 
LC from a JS function initiated by a body onload event.

It works on mac, but not on iPhone.

It is most peculiar and I am wondering if anyone else has encountered anything 
like this.

Re: Is there any way at all to have a mobile app simply resume rather than restart?

[Jonathan Lynch via use-livecode]

I read that on the forums, but I defer to Ralph on this.

I am playing with the hack now.

I think I could also have a legitimate reason for playing audio - changing the 
music as a user gets closer to a marker - but that would be a lot of trouble to 
set up right now.

Re: Is there any way at all to have a mobile app simply resume rather than restart?

[Jonathan Lynch via use-livecode]

It looks like the plist hack is not available in version 8. 

Choosing background audio works - but that means I need to have a plausible 
reason for having background audio or Apple reviewers might ding the app.

What a pain - why not just allow it to work the way other apps work?

Having to restart the app from scratch sucks. I can store the current state, 
but my users would have to wait for the map widget to reload every time they

Re: Sql problem

[Jonathan Lynch via use-livecode]

One quick note about base64encode:

LC adds linefeeds. After you base64encode, you may need to replace linefeed 
with empty in the variable.

Re: Incorporating ImageMagick into an LC program?

[Jonathan Lynch via use-livecode]

I don't know.

I was just wondering about interfacing through an LCB library or widget. That 
way, the LC folks would not have to be involved. 

If you don't mind a 2 second delay, the command line option works fine, but I 
think it should be faster.

I have all the tools I need now, to get Augmented Earth to market, so I am not 
too worried about. Still, it would be cool.

Incorporating ImageMagick into an LC program?

[Jonathan Lynch via use-livecode]

I once made an app that used command line calls to ImageMagick. That worked 
fine, but with a slight delay.

Would it be difficult to create an lcb script that directly interfaces with 
ImageMagick?

As long as you give them credit, their license would allow it.

Transparent browser widgets?

[Jonathan Lynch via use-livecode]

Apparently, both WebView (android) and uiwebview (iOS) have transparent modes.

Would it be easy for the LC team to implement a transparent mode for browser 
widgets, where the background color is transparent, allowing other objects to 
show through?

This would obviate the need for some the processor intensive image transfers in 
and out of the widget.

I know one would have to set the background-color of the body element to 
transparent and set a couple of settings in the WebView calls. Is that all it 
would take?

Re: SVG powered images

[Jonathan Lynch via use-livecode]

I feel like HH has an important point - this method uses a lot of processor 
power. We should minimize the burden on the processor (small animation, 
efficient JavaScript) and make sure our target users will consistently have the 
processing power to handle this kind of animation.

Re: SVG powered images

For svg animation, it seems like it would be more efficient to let the 
animation play in the widget and just periodically export a frame, rather than 
rewrite the svg every time.

Re: SVG powered images

[Jonathan Lynch via use-livecode]

Hey guys - I figured out a solution for that bug I had previously written a 
hack for. I use the image.onload handler in the JavaScript for this. It works 
consistently now. I just had to get my order of events correct in the 
JavaScript.

So please check out the new version.

Re: SVG powered images

[Jonathan Lynch via use-livecode]

To do an animation it would need a continuous but interruptible callback loop - 
with delayed sending for the next iteration after the previous iteration has 
finished.

I think it is doable.

Re: SVG powered images

[Jonathan Lynch via use-livecode]

I tried splitting up the chain like this. Even sending in 10 milliseconds did 
not work. The best test is to close LiveCode then open it back up and run the 
stack. If resizing one of the images works the first time, then it is good. 

However, delaying the command to send for the image does not work for the first 
resizing of the image in this scenario.

The way it is posted right now seems to work fine. I am going to leave it that 
way for now, while I try to find a way to detect when the canvas is fully 
rendered in JavaScript.

Re: SVG powered images

[Jonathan Lynch via use-livecode]

Did some more research. Yup - the image renders in the canvas asynchronously. 
So, on first load it is exporting the canvas image before that image is 
rendered.

Going to see if I can add an event handler that is triggered when the canvas is 
finished.

Thanks for the tip :)

Re: SVG powered images

Thanks Hermann 

If it were from that, then we could not switch back and forth between resizing 
different images. It would show the output of the previous image processed. But 
that does not happen.

I thought I chained the commands linearly, but I will check that again.

Thanks Ajelandro,

I have thought a bit about how to show a browser animation through an image

I think it can be done, but might use a lot of processing power.

Could be really cool with webgl animations.

SVG powered images

[Jonathan Lynch via use-livecode]

Hi everyone,

I just uploaded version 1 of a stack called "SVG Powered Images" onto 
livecodeshare.

Just go to livecodeshare.runrev.com and sort for the newest upload. This stack 
makes it practical to use fully scalable SVG files in your stack.

It is not as good as having a full SVG object, but it is the next best thing. 
It does use the browser widget, which could be an issue for some situations.

Peace,

J

Re: Using a hidden browser widget to create a perfectly scalable LC control

[Jonathan Lynch via use-livecode]

I agree - but I need fully scalable controls for Augmented Earth now, not 
later, and the current SVG objects are not complete.

My app uses the browser widget anyway, so not worried about the overhead.

Re: Using a hidden browser widget to create a perfectly scalable LC control

Hi Alejandro,

I am almost done. It has a weird bug where the widget only works after the 
first attempt for each image. It works great after that. I will get it, though.

Using a hidden browser widget to create a perfectly scalable LC control

[Jonathan Lynch via use-livecode]

I just did an experiment. It appears to be possible to have an image object 
that stores svg data in a custom property. It connects to a hidden browser 
widget to do the following:

- squirt the svg data into an HTML canvas
- resize the svg image using the setscale() method
- export the resized image (with transparency) to a variable
- pass that variable back to LC
- set the image content of the image to that variable

The entire operation took 4 milliseconds for a moderate sized svg image.

This means we could have svg-quality resizable images, for responsive design 
scripts.

I will try to create a browser widget with all of the necessary scripts in that 
one object, so you can import SVG files at will, display them in an 
auto-generated image, and painlessly resize the image at will.

To do that, one would have to include the browser widget in a hidden place on 
any stacks that use these pseudo SVG images.

Please let me know if you have any suggestions. I think I can get the stack up 
on livecodeshare in the next couple days.
