Re: Libraries To Contribute

[Mike Kerner via use-livecode]

Very true - I wasn't thinking of links, and I didn't even think of trying
to do it with the command-line.  I would like it to be cross-platform - at
least for desktops, but that's a good idea.  I line to figure out the
platform, and then a shell command would get it done, now wouldn't it?

Hi Todd,

Thanks for putting this up on GitHub. I have a favor to ask. Would you be
willing to change the extension of the file from .livecode to
.livecodescript?

.livecodescript is the extension that has been adopted by the mothership
for script only stacks. I've been using it myself along with others.
Recently I started looking at how to get LiveCode added as a supported
language to GitHub. I was pleased to find out that they pull syntax
coloring from a TextMate bundle. I was sad to see that in order to accept a
new language (in most cases at least) GitHub prefers to see it in
widespread use.

If everyone who posts files to GitHub differentiates binary stacks from
script only stacks using the extension then it will be helpful going
forward. As part of the submission process you have to send a search to
them that shows how often the language extension is used. A search that
doesn't show binary files would need to be submitted so the search would
filter by .livecodescript.

Re: iOS SDK Question

[Glen Bojsza via use-livecode]

I'm not sure so I am waiting to hear from Livecode support. 

But Pycharm tried a system where users would lose their ability to continually 
use the product after licenses expired and the users revolted and Pycharm 
reversed their policy.

I guess it comes to the question of how you want to work with your user base.

Once I get an answer I will post it here to confirm what the situation is.

No, because the problem apparently happens AFTER the text is placed. Everything

scp -rp some/folder/path target/parent/directory


does the trick, and can be called by shell.

It was explained to me that when the license expires, I would be unable to use

I might be mistaken. It may only mean I cannot create standalones and download

Re: DragDrop makes windows unresponsive OS X

[Bob Sneidar via use-livecode]

Interesting. I added the exit to top yesterday because it seemed to fix the 
responsiveness problem. It has been working without exit to top and pass 
dragdrop of over 2 years. I think it's because I am not acually allowing the 
drop to happen, but rather intercepting it, getting the dragData ["text"] and 
entering it into the field by script (would that be scripturally??) which might 
explain why the window becomes unresponsive the way I am doing it. The drop 
never *actually* happens, and that explains why exit to top corrects the issue. 

So here is the new code and this works a peach!

on dragDrop
   put cleanASCII(the dragData ["text"], cModeList, cCustomChars) into tDragData
   put titleCase(tDragData, false) into tDragData -- capitalize first letter of 
each word
   set the dragData ["text"] to tDragData
   pass dragDrop
end dragDrop

The trick then is to allow the drop to happen, but clean up the dragData 
["text"] first! Now it makes perfect sense. Thanks Jacque! Now I get to 
refactor the refactored refactorization that was initially refactored some time 
ago.

The first thing to try would be replacing "exit to top" with "pass 
dragdrop". If you don't pass the command, the drop doesn't happen.


Everything below is off the top of my head, untested, but here are some 
general ideas.


If "pass" doesn't work, try:

on dragDrop
  put the dragData ["text"] into tText
  set the dragData ["text"] to cleanASCII(tText, cModeList, cCustomChars)
  pass dragDrop
end dragDrop

And if that doesn't work, try:

on dragDrop
  put the dragData ["text"] into tText
  send "cleanUp tText" to me in 0
  pass dragDrop
end dragDrop

on cleanUp pText
  put cleanASCII(me, cModeList, cCustomChars) into me
end cleanUp

As I mentioned previously...I do not have an active subscription.

My license expired August 2016. 

When I log into my account the highest version of Livecode Indy that shows I 
can download is 8.1.3.

I even tried activating a 7 version of Livecode which was a year prior to my 
license expiring and it fails.

But I believe that I should still be able to use the Livecode Indy version that 
was covered prior to expiration. Hence, my email to Livecode support in asking 
what is the highest Livecode version that I can still use.

Re: DragDrop makes windows unresponsive OS X

[Bob Sneidar via use-livecode]

Here is a handler in a field script. The exit to top is necessary because of 
the issue. The source can be an email from the Mail app, or it can be text from 
an OCR'd PDF. The CleanASCII function is necessary because Acrobat will insert 
non-printing characters for what reason I do not know, that will crash 
Livecode. Since the issue occurs no matter the source, I do not think it's the 
nature of the data, especially since the data gets put into the field, so all 
functions have clearly returned (otherwise it would never see exit to top). 

constant cModeList = "uppercase,lowercase,numbers,custom"
constant cCustomChars = "!#$%&'*+-/=?^_`{|}~.@"

on dragDrop
   put cleanASCII(the dragData ["text"], cModeList, cCustomChars) into me
   exit to top
end dragDrop

Re: iOS SDK Question

[panagiotis merakos via use-livecode]

I think that if you log into your account area, you should see all the LC
versions you can access with your current license.

If you have an active subscription to Indy then you should be able to
activate any of them.

I suggest you just download and try, or log into your account area to see.

Best,
Panos

@Glen

Why are you still using LC 8.0.1? I suggest you download the latest stable
version, currently 8.1.3:

http://downloads.livecode.com/livecode/

Note that 8.1.3 on OS X 10.11.x will require Xcode 8.2.

Re: DragDrop makes windows unresponsive OS X

[Paul Hibbert via use-livecode]

Just tried a simple test on Mac OS Sierra / LC8.1.3 and it seems to work fine 
here. Is there anything else that could be interfering with the dragDrop?

Maybe the Message Watcher could give a clue as to what is happening.

DragDrop makes windows unresponsive OS X

[Bob Sneidar via use-livecode]

Hi all. 

Might just be me. I drag drop text onto a field with a dragdrop handler that 
essentially puts the drag data ["text"] into itself. Doing so with 8.1.3 seems 
to cause the window to become unresponsive, that is none of the controls work. 
I cannot click in fields, tab around, click buttons etc. However if I navigate 
to another window, and then back again it becomes responsive. Also, if I move 
the window with the title bar, it becomes responsive again. Finally, if I exit 
to top at the end of the dragdrop handler, THAT makes the window responsive. 
It's as though the dragdrop message is still in effect in limbo somewhere. 

This seems to be a somewhat recent development. That is, I don't think it has 
always been this way. Particularly in 8.0.x and prior, but I could not pin it 
down to a minor version.

This is half-baked and may not work at all on your system, but hopefully 
at least some of the magnification routine (which needs a tweak to 
better maintain proportion) will be useful to get you started:

The imageData of an image is the extracted color values for the pixels in
the image. Specifically, it is a sequence of bytes with each pixel
represented as xRGB. These are the bytes which are applied to the screen
when the image is rendered and does not include any alpha data (which is
specified using the alphaData property). To set the imageData you need to
set the width and height of the field first.

Both of these do the same thing - (3) is short hand for (1).

The 'text' of an image is the original image data from a format such as PNG,
GIF etc.
i.e. the content of a PNG file or GIF file.

In general, (2) or (3) is better than (1) as (1) is considered an 'image
editing'
operation and as such will cause a recompression of the data in some
fashion. Also
(2) and (3) will automatically set the size, and alpha channel of the image
appropriately.

> And is there any explanation why the upward compatibility of solution 
> 1 is broken?

If there is a difference here then it is a bug - although please do check
that the width/height of the image is the same, and also transfer across
alphaData too.

I'd recommend using (2) or (3) - or, indeed, using referenced files instead.
The engine will automatically cache referenced images and share the
underlying decompressed data.
i.e.

set the filename of image 1 to "foo"
set the filename of image 2 to "foo"

Will first resolve "foo" as an absolute path, load that image file into a
cache if not already present and attach the decompressed image data to the
image object. Then, when the second image's filename is set, it will find
the image is already in the cache and just use the decompressed image data
attached to that file in the cache.
i.e. The two images share the same pixel data in memory.

Warmest Regards,

Mark.

Re: differences between text/imagedata of image in LC6/8

[Mark Waddingham via use-livecode]

Hi Tiemo,

in an old program I obviously tried to be very technically over correct 
when

copying an image and did:

1.   set the imagedata of img 2 to the imagedata of img 1

This worked up to LC 6.7. In LC8/9 I get a corrupted image (black and
stripes) in the target image.


The imageData of an image is the extracted color values for the pixels 
in the
image. Specifically, it is a sequence of bytes with each pixel 
represented as
xRGB. These are the bytes which are applied to the screen when the image 
is
rendered and does not include any alpha data (which is specified using 
the
alphaData property). To set the imageData you need to set the width and 
height

of the field first.


What works in LC8/9 is

2.   set the text of img 2 to the text of img 1

and

3.   put img 1 into img 2


Both of these do the same thing - (3) is short hand for (1).

The 'text' of an image is the original image data from a format such as 
PNG, GIF etc.

i.e. the content of a PNG file or GIF file.

What is the correct syntax today? Is solution 2 and 3 the same and just 
an
alias (what it seems to me) or are there differences in details I do 
not

see?

Magnification

[Vokey, John via use-livecode]

I am working on a stack that has reduced images on a card, but I want the user 
to have the ability to magnify those images (at least the part they are 
hovering over) as they hover over them.  But, not the card images, but the real 
higher resolution images stored in separate files.  I suspect there some among 
you who have done this: I am seeking the code in a bit of a rush.
