Still there:
https://www.fourthworld.com/embassy/articles/revolution_message_path.html

Since I made that back in the day (the file name hints at its age), I've 
discovered a pretty great resource mysteriously unknown in our 
community, but surprisingly comprehensive and includes a nearly 
identical diagram.


It has more than 650 pages of comprehensive info on using LiveCode, 
broken down into well organized sections and subsections, often with 
illustrations and screen shots, all put together in a well-indexed PDF.


They call it "LiveCode User Guide", and it's been secretly bundled with 
every release of LiveCode for several years. :)


I'm having fun there, but seriously, the User Guide has been pretty good 
in recent years. I'm often surprised at how the answers to many forum 
questions are covered well in it, yet when I ask about it most people 
don't even notice that it's there, the second-from-the-top item in LC's 
Help menu.


The Message Path discussion starts on p 101, with a pretty good diagram 
on p 102, including a distinction between Groups and Backgrounds.


In fact, p 105 includes a discussion of that distinction far more 
concise yet no less helpful than my longish post here the other day.



PS: I was going to include a link to the Github repo for anyone who 
might want to help with errata or enhancements to the docs, but I 
couldn't find the PDF sources in the /docs folder.  What am I missing?

2013 was LC's massive Kickstarter campaign.

For a system reflecting general searches, I would expect a decline in 
general attention after that.


Among programmer-specific resources used for TIOBE, a modest increase is 
fairly consistent with what I see subjectively from new membership rates 
in the forums.


Not that TIOBE is perfect, and it is indeed useful to use as many 
metrics as practical for business planning.  But the industry seems to 
favor TIOBE for ranking programming languages, and there may be some 
good reasons behind its popularity for that metric.

This way I have control over the load process and can let users bail out.

It is a lovely gif, but it "hangs" when the processor on phone is doing 
something else. It there are way to keep it's frames "circling" until get we

Re: Java update?

[Colin Holgate via use-livecode]

I don’t know if your version of LiveCode is an example, but many applications 
need Java 6 in particular, and macOS comes with Java 8. The solution is to 
install the legacy version of Java as well:

Re: LC #48 @TIOBE

TIOBE is obviously measuring a bunch of other things and assigning a fair bit

LiveCode (#48/0.18%) it's chalk and cheese...

Re: LC #48 @TIOBE

[Terry Judd via use-livecode]

Very similar results just with 'livecode' as the search term...

https://trends.google.com/trends/explore?date=today%205-y&q=%2Fm%2F0490j1,Livecode

...and the LiveCode website is the first search result on Google and the 
Wikipedia page on LiveCode the second so it would seem to be a reasonable 
approximation of general search interest. Might be interesting to do 
comparative Trends searches of some of the other languages just above LC on the 
TIOBE index to see how they fare.

Interestingly, Armenia doesn't rate a mention with livecode as a search term 
(vs livecode as a programming language).

Re: Groups in the message path: Trapping Mouseup

Mark Waddington gave the answer if need.

I really want "shared groups" and not "backgroundGroups"

Then the scripts are encapsulated. I turned off backgroundBehavior on all 
groups.

A click on top layer button (no script) now  registers in the stack script with 
its target.

I tried it, Yay! After 25 years, still learning….





So if I have a button X with a mouseDown handler in a Group Y also with
a mouseDown handler and in my card script (or stack script) also have a

Windows Standalone Performance

[Bob Sneidar via use-livecode]

Hi all. 

Just wanted to give a heads up on what I think is the greatest Windows 
Standalone performance killer. 

When I first began to develop, it was done entirely on a Mac, and before I had 
any thought about how a standalone would work in a multiuser environment. As 
such, it was easy for me to simply save anything I wanted to persist between 
sessions as aomething in the stack, a settings card at first, then later as 
properties of each stack and the main stack. To ensure that these properties 
persisted I saved each sub stack when I updated any of those properties. 

On a Mac, for whatever reason, the performance hit was insignificant. On 
WINDOWS however, it became painfully clear to me that the performance penalty 
was VERY substantial! I can watch the folder containing the standalone stacks, 
see the temp files being created, one mississippi, two mississippi, three 
mississippi, around 4 misssissippi the temp file goes away. 

Since I do a lot of setup, I was saving the stack(s) multiple times just 
launching the app! And it was killing the performance. After putting in the 
condition not (the platform contains "WIN") before my save statements, 
performance, while not up to snuff compared to the MacOS, is actually quite 
acceptable. 

If you are saving your stacks by script when opening and closing, and you are 
experiencing long delays, consider going a different route. In fact, consider 
moving all your "settings" and persistent data to a memory array or database, 
and then writing it to disk either occassionally during idle time, or on quit. 

Bob S

Re: Android Scrolling Field - 9.6.dp1 - Receives MouseUp/Down

[J. Landman Gay via use-livecode]

I think you're seeing this bug, which was fixed in 9.0.5:


Without a mouseUp message, it is impossible to detect a swipe within a 
scroller, which was another fundamental issue that has been corrected. 
Users depend on swipes, and on mobile it couldn't be done. Taps worked, 
but all user gestures were detected as a tap instead of a swipe. It was 
finally fixed.


Here is what I use to detect taps and swipes on a native scroller:

**
-- behavior script, assigned to all scrolling controls:
local sMouseLoc,sStartLoc

on mouseDown
  put the mouseloc into sMouseLoc
  put sMouseLoc into sStartLoc
end mouseDown

on mouseUp
  put "" into sMouseLoc
  if abs(the mouseH - item 1 of sStartLoc) <= 10 and \
abs(the mouseV - item 2 of sStartLoc) <= 10 then
send "doScrollerTap" to the target
  else if isSwipe(sStartLoc) then
doSwipe sStartLoc -- navigate
  end if
end  mouseup

on mouseMove x,y -- desktop scrolling, you can omit this if you don't 
need it

  if isMobile() or sMouseLoc = "" then exit mouseMove
  put abs(x - item 1 of sMouseLoc) into tHDist
  put abs(y - item 2 of sMouseLoc) into tVDist
  if item 2 of sMouseLoc > y then -- pushing up
if the name of me contains "image" then set the hscroll of me to 
the hscroll of me + tHDist -- bgImg okay

set the vscroll of me to the vscroll of me + tVDist
  else if item 2 of sMouseLoc < y then -- pushing down
if the name of me contains "image" then set the hscroll of me to 
the hscroll of me - tHDist

set the vscroll of me to the vscroll of me - tVDist
  end if
  put x,y into sMouseLoc
end mouseMove

on mouseRelease
  put "" into sMouseLoc
  put "" into sStartLoc
end mouseRelease


This requires that a "doScrollerTap" handler is in the message path if 
you want to detect taps. Or you could send a different message.


Here is the handler that detects swipes:

**
function isSwipe pStartLoc -- calculate if a gesture is a horizontal swipe
  -- called from scrollerBehavior
  -- pStartLoc = initial mouseloc at mouseDown
  put abs(the mouseH - item 1 of pStartLoc) into tHDist
  put abs(the mouseV - item 2 of pStartLoc) into tVDist
  return tHDist > tVDist -- swipe
end isSwipe
**

On iOS you could also try playing with canCancelTouches and delayTouches 
to see if that helps. Android doesn't support those though. I did set 
both to false in one case and it seemed to help when used with the above 
handlers.

For IOS 13 we have to use the latest and it is a real pain to work out when
the  Android scroller went wrong within the

with.

This is a SHOWSTOPPER we have been mostly testing the IOS apps that work

if we didn't have a "long" list that needed to scroll and select. Only
noticed with "Real" data with a long list.

Gone back to 9.5 and the problem is still there.

will try 9.05 and see what happens.

On 9.6 dp 1  I was testing on iOS for a week.

Then I tested on Android. Surprising new behavior in the mobileScroller:

It receives the mouseDown as soon as you scroll, or mouseUp after you
scroll. This does not happen on iOS, not did in happen in 9.5 on Android.

How can I prevent this and only trigger a "touch" when the user is not
scrolling?

Re: Groups in the message path: Trapping Mouseup

Correct?


Only if you want to handle the mouseUp message *first* in the background 
group script and *then* in the stack script.




remember the use case:
we do not want and script in *any* button or top object that receives a click or touch.  
The card becomes a pure "view" object.


Q: Why do you have a background group? And mouseUp handlers in it? This 
will catch any mouseUp messages that aren't already captured by controls 
on the card, and in addition will catch mouseUp messages if you click on 
the card itself.


Why not just have the mouseUp handler in the stack script?

Or put the buttons into their own (not background) group and have the 
mouseUp handler there?


Or have a behavior script for the buttons or group that handles the 
mouseUp messages?

Re: Groups in the message path: Trapping Mouseup

[Paul Dupuis via use-livecode]

So if I have a button X with a mouseDown handler in a Group Y also with 
a mouseDown handler and in my card script (or stack script) also have a 
mouseDown handler


If I click on button X and I only want button X to handle the mouseDown, 
I do not 'pass mouseDown' in the button X mouseDown handler


If I click on button X and I also want another mouseDown handler in the 
message path - in addition to the one in button X - to do something in 
response, then I need to 'pass mouseDown' in the button script. In this 
example, a pass mouseDown in the button mouseDown handler passes the 
message to the group that contains the button. If that group's mouseDown 
handler also does a pass mouseDown, then the card or stack gets the 
mouseDown as well. If they do not pass the message its stops there.


Richard Gaskin, at one point, had a really excellent diagram of the 
LiveCode message hierarchy. If he sees this post and still has it 
perhaps he could post a link to it.

@paul

If you have groups where you need to pass a mouseDown (or mosueWhatever)
mesage to the card or stack, just add a behavior to the group for a
script that contain handlers like

on mouseDown
   pass mouseDown
end mouseDown

on mouseUp
   pass mouseUp
end mouseUp

Although if there is no handler for the mouse event it should pass to
the card and then the stack and then any library or backscripts and then
the engine.

That's it! Thank you!

If you turn 'background behavior' off, then your shared group should no
longer receive messages after the card does.

I've added Windows support and the ability to pass boolean options so that
you can control the behavior of htmltidy when it cleanses the HTML input.
I've added some sample settings to the test stack for testing.

If anybody would like to add Linux support it should just be a matter of
following the build instructions provided by htmltidy and added the
resulting library to an `x86-linux` folder in the code folder:

https://github.com/trevordevore/lc-htmltidy/tree/master/code

You can find a link to the htmltidy build instructions in the product

Re: Java update?

[J. Landman Gay via use-livecode]

I'm running Java 8 with a lower build number (211 if I remember right, but 
I'm not at my Mac to check right now.) Java is required to build LC apps 
for Android, which I do all the time. If you look in LC mobile preferences 
you'll see the place where you need to specify your Java installation.
