Re: Would anyone miss convertOctals?

So I'm currently sitting here about to embark on fixing 
 (which is the final thing 
to sort out before being able to merge my constant expression patch) and I was 
reminded of 'convertOctals'.

Now, generally, I am somewhat averse to actually removing any language feature 
(even those we have deprecated, unless we absolutely have to!) - however, I 
would really like to make convertOctals have no effect at all in 10.0+ as it 
adds a disproportionate amount of complexity compared to (what I think, at 
least) its utility is (particularly in the context of things 'coming next' like 
the script compiler).

So three questions:

 1) Do you know what convertOctals is, and what it does?

Nope

 2) If you do, have you ever actually used it in any scripts which are actually 
still in use?

Nyet

 3) If you do use it in any scripts which are still in use, would you be 
willing to change them to not use it?

N/A

 4) If you do use/have used it, had you ever noticed that it has been slightly 
broken for years?

Wait, you said three questions. But no.

Now, its always better to offer a carrot when there is a stick (or in this 
case, an axe) being wielded and the carrot in this case would be to expand the 
numeric literal syntax to add both explicit octal and binary number literals 
alongside hexadecimal:

   0xabcdef - hex literal
   0o777 - octal literal
   0b101110101

The key difference between 0o777 and using 0777 (with convertOctals true) is 
that the former is not ambiguous at parse time, it doesn't require a runtime 
property set to true in order for the engine to convert the string to a number 
correctly.

Please let me know your thoughts :)

Warmest Regards,

Mark.

P.S. In the scheme of 'breaking changes' - we've already made a number of them 
for 10 already, and my gut tells me removing convertOctals is likely to cause 
less consternation than those we already have - but I could be wrong!

Re: HTML font size in percentages

[Devin Asay via use-livecode]

Jacque,

It sounds like the HTML tags are setting the size for runs of text in the 
field, so you can’t just set the textSize of the field?

Are there varying sizes of text runs in the field? Could you set the textSize 
of the char 1 to -1 of the field to empty, then set it for the whole field? In 
one project I’ve implemented a feature similar to what Bob was talking about 
where I increment the textSize of the field by 1 point using Cmd/Cntl + or -.

fields don't seem to support that. Is there a trick or do I need to do a series 
of replacements? I'm afraid that will be too slow, there's a lot of text.

Re: Movie text tracks

[Devin Asay via use-livecode]

Sorry, I left out the punch line.

My original need was simply to extract the text tracks from the old .mov files. 
It turns out you can do that, after a fashion, with QT Pro, but it comes out 
with lots of binary cruft. I found out you can also do this with ffmpeg, the 
Swiss Army Knife of video tools. This website explains how:

https://forum.videohelp.com/threads/403944-Extract-and-convert-QuickTime-7-Pro-TextTracks

Neither method was perfect, but both were good enough for what I wanted.

Movie text tracks

[Devin Asay via use-livecode]

Hi all,

I’m resurrecting some QuickTime movies from years ago, and some of them have 
text tracks. (Remember those?)

In the LC player object you can still see that there is a text track with `put 
the tracks of player 1`. But there doesn’t seem to be a way anymore to show 
text tracks, either in the player object or in QT Player. All of the hits I get 
on the topic in a DuckDuckGo search are 15 - 20 years old.

Anybody know how to show, or at least recover, old text tracks from video files?

(Man I hate it when the technology gets *less* capable!)

Obviously, it was possible in earlier versions of LC.

So, could someone be kind enough to make a quick test with the most recent 
versions of LC, by typing text inside a field, if special characters can be 
used, like alt+144 for É, and possibly on azerty and qwerty keyboards ?
Thank you in advance.

Le 2022-05-10 17:53, Paul Dupuis via use-livecode a écrit :
I thought I recalled a bug in the LC engine where using the keyboard
method of typing the character code, press ALT, and then press X. For
example, to type a dollar symbol ($), type 0024, press ALT, and then
press X, didn't work in Livecode. However, I just tried searching the
Livecode Quality Center for a bug number and couldn't find it so
perhaps I am mis-remembering.

Re: Speed up a slow loop

[Devin Asay via use-livecode]

Jacque,

Have you tried

put the keys of sDictFile into tCorrWdList
repeat for each line I in pList
   if I is among the lines of tCorrWdList then
  put I & cr after tCheckedList
   else
  put I & cr after tNonWords
   end if
end repeat

I just wonder if there is some overhead with checking the array on each 
iteration.

But like you say, it may not be the repeat loop at all.

In my Boggle game I have an array containing dictionary words as keys, split as 
set, so all values are "true". I need to compare those keys with a list of user 
words and get back a list of good words and a list of illegal words.

The loop takes forever. Here it is (sDictFile is a script local):

 repeat for each line l in pList -- pList is the user word list
   if sDictFile[l] = true then put l & cr after tCheckedList
   else put l & cr after tNonWords
   wait 0 with messages  -- prevent ANRs
 end repeat

I added the wait because my Android phone was putting up an "app not 
responding" warning while the loop was running (or just after, hard to tell.) 
The loop should be much faster than that. When I added some timing checks 
though, the timer says the loop takes between 0 and 1 millisecond, and yet the 
wait on screen remains.

With a 3-word user list, the loop takes 4 seconds. With an 8 word user list the 
loop takes 6 seconds. The more user words, the longer the wait.

Even stranger: on my cheapo Android tablet with 4 megs of RAM running Android 9 
the response is nearly instantaneous, even if the user list has 200+ words. On 
my Pixel phone with 8 megs of RAM and Android 12 the response is slow enough to 
trigger the ANR with only 3 words. I'm building for ARM 64.

I've tried any number of workarounds without luck, on both LC 9.6.6 and LC 
10.0.0. Any ideas? I have a feeling it isn't the script per se, it's something 
else.

Re: Keep stack proportions when resizing

[Devin Asay via use-livecode]

Peter,

I asked this question several years ago and what I gathered is that it’s not 
easy because window resizing is under the control of the operating system, and 
LiveCode can’t really override it.

My attempts were not completely satisfactory:

I have a stack that I want to constrain to a 4:3 ratio when resizing, with a 
minimum stack size of 800 X 600. A search of the archives didn't yield any 
relevant results.

If I do this (in the resizeStack handler):

 put the topLeft of this stack into tAnchorPnt
 set the height of this stack to (pNewWdth * 3) div 4
 set the topLeft of this stack to tAnchorPnt

it works as long as my drag on the resize gadget has a horizontal component.

Likewise, this works:

 put the topLeft of this stack into tAnchorPnt
 set the width of this stack to (pNewHgt * 4) div 3
 set the topLeft of this stack to tAnchorPnt

as long as there is a vertical component to the drag.

This:

 put the topLeft of this stack into tAnchorPnt
 if pNewWdth <> pOldWdth then
   set the height of this stack to (pNewWdth * 3) div 4
 else
   set the width of this stack to (pNewHgt * 4) div 3
 end if
 set the topLeft of this stack to tAnchorPnt

Just produces bizarre results.

After I posted about it,I did get a few workarounds.

Scott Rossi suggested that you create your own resize handle instead of using 
the one built-in to the window:

One way to do this is to use a dedicated object for the resizer and to
calculate the new dimensions before resizing the stack.

Execute this in your message box:
go url "http://www.tactilemedia.com/download/constrained.livecode;

This demonstrates one way to do a 4 x 3 ratio stack.  I'm not sure if it's
possible to get the window refresh to completely sync with the location of
the resizer, but maybe this will get you close.

Roger Eller and Berndt Niggeman suggested that you can’t do it in real time, 
but you could “snap” it to the correct size after resizing:

I am with Roger on this.

here is a little code snippet that does constrain the aspect after resizing

---
on resizeStack pNewWidth, pNewHeight, pOldWidth, pOldHeight

  -- block repeat loop if you want to have all the changes occur after last
resize, kind of animation
  repeat for each line aMessage in the pendingMessages
 if aMessage contains "adjustRatio" then cancel item 1 of aMessage
  end repeat

  send "adJustRatio pNewWidth, pNewHeight, pOldWidth, pOldHeight" to me in
0 milliseconds
end resizeStack

on adJustRatio pNewWidth, pNewHeight, pOldWidth, pOldHeight
  put round (pNewWidth / 2) into tNewHeight
  put the rect of me into tRect
  put item 2 of tRect + tNewHeight into item 4 of tRect
  set the rect of me to tRect
end adJustRatio
---


Dunbarx suggested trapping the resizeStack handler, but that doesn’t seem to 
work just right, probably because the message is sent *after* the resize, not 
before.

Hope this helps.

- Devin

Re: Drag and drop within a list field

[Devin Asay via use-livecode]

Hi Paul,

Some years back Scott Rossi created a nifty little demo called GetInLine that 
shows how to do the interface part of drag-reordering. It’s in his archive at 
http://tactilemedia.com/blog/2018/05/12/blasts-from-the-past/. It might give 
you a good foundation, even if you don’t use the exact interface he created.

I don’t think the data part of it should be too hard; just make sure you keep 
the visible list and the custom property synched the same. Or you could 
possibly use hidden text or metadata tags in you visible list to embed the type 
for each line.

Hope this helps.

Re: Stuck on native database functions

[Devin Asay via use-livecode]

Bob,

A couple of things: You should either be passing variable names, not variable 
contents, so put your variable names in quotes.

revExecuteSQL “tDBID", “tInsertSQL", “tControlName”, etc

OR  you should be passing the name of an array variable, whose keys are numeric:


revExecuteSQL “aRecordData”

Not tested, but I’m pretty sure if you sort these things it will start to work 
for you.

Re: Stacks not removed from memory?

[Devin Asay via use-livecode]

Marty,

I had intended to respond to this, but got busy with other things. 

I have seen what you’re describing on all of the recent releases—9.5 - 9.6.x; 
i.e., a stack with destroyStack set to true, then closed, is not always removed 
from memory. Sometimes this has caused an infinite loop with the Save - Purge - 
Cancel dialog. I would report it, but I haven’t been able to come up with a 
reliable recipe. It’s a problem that I would like to nail down and squash.

SSL Error - question from Stack Overflow

[Devin Asay via use-livecode]

Hi all,

I came across this question on stack overflow. I like to try to give good 
LiveCode answers there when I can, just to do a little to boost the reputation 
of the LC community there. But I don’t have a clue on this one.


A Livecode script:
get URL 
"https://www.uspto.gov/patent/laws-and-regulations/patent-term-extension/patent-terms-extended-under-35-usc-156;
Winds up with the following in "the result":

 tsneterr: (56) SSLRead() return error -9806


I tried setting libURLSetSSLVerification to both true and false, but got the 
same error each time. Any ideas why this is happening, and is there a solution?


I verified that this error is returned consistently in the result. Anybody have 
any ideas? Charles, are you lurking perhaps?

Re: Using MySQL on (headless) Linux

[Devin Asay via use-livecode]

Ben,

I have seen the “invalid database type” error on Linux because of a case error. 
Make sure you use “mysql” as the database type, not “MySQL” or anything else 
with upper case letters. LiveCode is not case-sensitive, but Linux is.

Hope this helps.

Re: OT Friendly customers....

The H word gets tossed about far too casually nowadays. 

Commenting on alleged abuses perpetrated by government agencies is not hate. 
And if it is, then what are allusions to “dark forces” and “fake news”? 

Regardless, it’s just the wrong forum.

And also, “cheese!” (That’s your cue, ListMom.)

Re: Some sad news

[Devin Asay via use-livecode]

I think we all have been dazzled by what Hermann was able to do with LC HTML5. 
Our community has been enriched by Hermann and many others for whom LiveCode 
and the idea of “coding for everyone" is a passion. He will be missed. 
Condolences to his family.

As others have noted, we also remember other LiveCode late-greats: Mark Smith 
and Eric Chatonet. I’m sure I am forgetting someone, but their legacy lives on 
in their generous contributions to the LiveCode developer community, Thanks to 
all who continue to keep their work available.

Re: Script colorization not working

[Devin Asay via use-livecode]

Thanks Panos, and Bernd also for the tip on the new version of Source Code Pro.

The student was indeed using Source Code Pro, and when she changed to a 
different font for the script editor, it fixed the problem.

Script colorization not working

[Devin Asay via use-livecode]

Hi all,

One of my students is having a problem where the script colorization is not 
working completely. That is, the bold face style is applied for things like 
**on** mouseUp and **end** mouseUp, and commands are boldfaced. But nothing 
else is colorized.

We have checked all of her script editor preferences. Colorization is set to 
default.

There is nothing in the script editor menu that would affect this as far as I 
can tell. 

My student likes script colorization and finds it very helpful, so she’s 
anxious to get it fixed.

Has anyone ever seen this? Any suggestions for how to fix it?

She’s on Mac, probably Catalina, LiveCode Community 9.6.1.

Audio recording in LC community on Windows?

[Devin Asay via use-livecode]

HI all,

From the beginning of Rev/LC we could do basic audio recording cross platform, 
at least on Mac and Windows, using the QuickTime framework. QT went away a few 
years ago, and it took some time for that capability to be restored. On Mac we 
can do it in all LC editions, including Community, using mergMicrophone. 
However the mergMicrophone external is not available on Windows. Now you can do 
audio recording on Windows using camera controls, *but only in Indy and above*. 
In other words, unless I have missed something, Windows Community users have 
lost this functionality. There is no longer feature parity between Mac and 
Windows on Community. That’s a problem for me in teaching LiveCode in my 
college level courses. (Linux users, I’m not trying to ignore you here; I just 
don’t have a firm grasp on what’s possible on Linux.)

So my questions:

- Is there a way to do audio recording in LC Community on Windows that I’m not 
aware of?

- If not, should I approach the mother ship and request that we get feature 
parity on all the desktop platforms?

Thanks all. I look forward to hearing your ideas.

Devin

Re: Converting from unicode to ASCII

[Devin Asay via use-livecode]

Hi Jacque,

Have you looked at the normalizeText function? I’m not sure that would help, 
but maybe it’s a start.

But it that doesn’t help, and if nobody ever sees the filenames, why not just 
loop through the string and delete anything that’s not in ASCII range?

Externals Question from Stack Overflow

Once more, this time with the link.


Hi all,

I came across a question on Stack Overflow from a sight-impaired user who is 
trying to figure out how to write and test a LiveCode external. I am pretty 
ignorant about externals in general, so I don’t think I can help in this case. 
But if anyone here feels inclined, I think it would help this user, and boost 
the number of responses to LC questions on Stack Overflow.

Re: Building a standalone warns about duplicate stacks

[Devin Asay via use-livecode]

Jaque,

I’ve seen this when building standalones with stacks that are using library 
stacks, and the same library stackflles are included in the standalone build. 
Apparently the included stacks are opened during the build process, thus 
colliding with the library stacks already in memory. If this is the problem, I 
suppose a workaround would be to stop using the library stacks before running 
the build process.

Hope this helps.

Re: mergAV Select specific rear camera

[Devin Asay via use-livecode]

Andrew, 

I’m not sure about mergAV, but if you gave an Indy license you might want to 
check out cameraControl, which keeps getting better with each new release. I 
was playing around with it in 9.6.0DP4 yesterday, and it seems pretty capable. 
It also has the advantage of being cross-platform on Mac, Win, iOS, and Android.

Re: Livecode HTML5 and SQL

[Devin Asay via use-livecode]

That’s good to know, Matthias. So it seems that what you’d have to do is, still 
do the MySQL I/O in LC Server scripts, but also dynamically construct the HTML 
output in your LC server scripts, so that the calling HTML5 app could make 
sense of it. 

Am I interpreting the situation correctly, Matthias?

Re: Livecode HTML5 and SQL

Colin,

I haven’t tried it myself, but I would think you’d have to write an API layer 
using LiveCode Server scripting. All of the MySQL reads and writes would take 
place in your .lc scripts on LC Server. Then it would be simple, RESTful http 
calls from your HTML5 app. Of course, this all depends upon whether the 
internet libraries have been ported over to the HTML5 platform. LiveCode 
Server—I’ve done lots. HTML5 deployment, almost none.

Hope this helps.

Re: Can a stack know which standalone engine it's running on?

[Devin Asay via use-livecode]

But doesn’t the processor just report on the host operating system? I wan’t to 
know which LiveCode engine is running.

Here’s the scenario:

I have a LiveCode splash screen-type application for which I’ve compiled both 
Windows-32 and Windows-64-bit versions. The standalone opens a stack that 
contains the actual business logic. In my About dialog, I’d like to be able to 
report which LiveCode engine the stack is running under. Do we have a way to 
get that information?

Re: Scrollbar scale value not showing in Windows

[Devin Asay via use-livecode]

Verified on Windows 10. The default size of the scrollbar object obscures the 
scale values. Just increase the height of the scrollbar/slider (if your sb 
orientation is horizontal) or the width of the sb (if the orientation is 
vertical.)

Re: Making an iOS app look like one

[Devin Asay via use-livecode]

Hi Graham,

TL/DR: It’s doable, but there is a learning curve.

Making your apps look native is doable, but how to get there is a mixed bag. As 
you’ve discovered, you have to use a range of capabilities.

1. Widgets. They are mostly straightforward to figure out. See my lesson at 
http://livecode.byu.edu/objects/widgets.php. I also created a sample stack with 
mobile-appropriate widgets at 
http://dight310.byu.edu/lesson_materials/13-Mobile_native_controls/mobileAndWidgets.livecode

1.a. Control over SVG icons. You have quite a bit of control over which icons 
you can use, by using icon families. See my stack SVG Icon Family Maker in 
Sample Stacks (AKA revOnline). You can go out on the internet and find an SBG 
icon set you like, import them into your stack, and put them into an icon 
family. Then you can set the icon family when you’re choosing icons for your 
SVG widget or Navbar widget.
1.b. Mobile native controls wrapped into widgets. They include the Android 
Native Button, Android Native Field, and iOS Native Button. The Android ones 
seem alright, but the iOS button just displays a label in the app, nothing 
else, no outline or background color. So these widgets seem incomplete. 
Standard LiveCode buttons using custom icons might be a better choice for now.

2. Mobile Native Controls. See my lesson at 
http://livecode.byu.edu/mobile/device-specific.php. I divide them into a few 
different groups.

2.a. Stuff that “just works”. Basically ask and answer dialogs just work right 
on mobile. Easy. Popup keyboards in fields also appear on mobile without any 
effort.

2.b. Stuff that’s pretty easy, but use mobile-specific commands.
- mobilePick - this is probably what you want in place of a radio button group.
- mobilePickDate
- mobilePickPhoto

2.c. Mobile native controls. These have to be completely scripted, but are 
doable. As for sizing and placing, I usually use a place-holder control during 
development and set the rect of the mobile native control to the place holder, 
hiding the place holder when running in the mobile environment.

Sample stack for native controls at 
http://dight310.byu.edu/lesson_materials/13-Mobile_native_controls/testMobileControls.livecode

Hope this helps.

Devin

Folks, I know this is a desperately naive question, but as I progress with my 
first serious attempt at an iOS app, which I’m trying to do in a hurry with 
only my experience of developing LC desktop apps to go on, I am struck by how 
un-iOS-like it looks. Richard Gaskin has already suggested that I look for good 
practice amongst existing apps from all sources, and I’ve tried to do this. 
Where I come unstuck is how to imitate the ‘look’ of such apps.

I am trying, for example by getting the Native Control Widget pack from the LC 
store, and by attempting (but not so far succeeding) to understand the LC 
lesson about Native text controls, especially how I can create such controls in 
the first place.

My app is not outrageously complicated. What it needs is

 -  Fields to display information, some of which must allow input via keyboard 
or pasting. Although there is a Native Android Field widget, there isn’t one 
for iOS, so I don’t know what my options are. I want the kind of fonts and font 
sizes that are typical of iOS, but so far I haven’t found a reference to these 
properties in the LC documentation. I found a command, mobileControlCreate, 
which it appears can only function dynamically in a mobile app, which seems to 
mean I can’t create and place controls until the app is running. I find that 
confusing.

 -  Small, tidy icons, for use as the equivalent of menus or menu items, for 
example acting as links to various settings cards - so typically an image like 
a cogwheel for example. I would like these to be SVG, but none of LC’s SVG 
images have the necessary unchunky look. Do I have to create them from scratch 
(it would not be the end of the world if I did, but I imagine that there’s a 
library of them somewhere).

 -  “Done” type buttons (there is a built in widget for this but it doesn’t end 
up looking like the ‘done’ buttons I see on typical apps) and other buttons to 
start off processes or displays.

 -  Some kind of control that acts like a radio button group, so that one 
option is chosen to the exclusion of any others in the group (I suppose it’s a 
picking list, but I don’t know how to implement such a thing in an 
iOS-compatible way and the widgets on offer are specialised to date and time)

LC Support has been helpful in pointing me at various lessons, but I have 
obviously missed masses of stuff which must be there somewhere. As usual I am 
searching for pointers and examples in order to try to fast track this 
development.

Sorry for asking yet more questions.

Graham,

Not really visualizing what you’re seeing. When you choose Xcode from your 
LiveCode mobile support preference pane, all you should have to do is navigate 
to Xcode using the Add Entry button, choose Xcode, and the square next to the 
iOS section should turn green. If you see the green square you should be good 
to go to do Test deploys to the iOS Simulator. 

It’s all about the Green Square!

Re: Building a Board Game

[Devin Asay via use-livecode]

Roger,

Rather than moving an object, think about using button icons.  This is the 
basic process:

- on mouseDown: check the icon of the target, set the icon of a hidden, moving 
button to the same icon, set the icon of the target to 0, set a 
flag—isDragging--to true, show the hidden button

- on mouseMove: if isDragging is true, set the loc of the moving button to the 
mouseLoc

- on mouseUp: figure out which square you’re over, set the icon of that button 
to the icon of the moving button, hide moving button, set isDragging to false.

I made a rudimentary chess game that uses this technique, check it out here:

http://dight310.byu.edu/lesson_materials/07-arrays/chessGame-final-key.livecode

Click the Clear Board and Setup Game buttons first to set up the game board 
array. Game state handlers are in the card script; game piece moving handlers 
are in the game board group script.

Hope this helps.

Hi All - sorry this is a bit long, but I need help.

I’m a long term LC developer who more or less retired from development a couple 
of years ago, but I’ve kept on lurking in this list and trying rather 
hopelessly to remain up to date. My experience has been mostly on desktop apps, 
with a little iOS work. I haven’t ever done much on Android. I have just about 
retained my credentials as an Apple developer.

Now I find I really want to develop a mobile app at speed, and deploy it.

I don’t anticipate all that much difficulty in creating my app in the sense of 
designing and coding it - this can call on my own quite extensive experience of 
the past, the LC documentation and this invaluable list. I can reasonable hope 
to create a prototype in a few days. However there is a massive gap: testing 
and deployment.

I don’t have access to my most recent development machine (it’s in another 
country and I’m self-isolating), so I am working with an iMac that can only run 
MacOS High Sierra (and Windows 10 via Parallels, but I was hoping not to go 
there for this project). Now, I clearly need to organise the right version of 
XCode and the right SDK for my iOS development, and I need to do the equivalent 
thing for Android - and I don’t know how to do it.

For iOS, I THINK I need XCode 10.2, which I’m trying to download to replace the 
copy of 9.2 already on my machine. I obviously need to work with a compatible 
SDK. For Android, I don’t know where to start, so for now I am putting this on 
the back burner, but I will have to return to it eventually. Even when I’ve 
lined all this up (if indeed it’s feasible), I then need to remind myself how 
to test via simulators (I used to be good at this, so maybe that is not so 
scary, but I am not at all up to date) and then I need to get the app onto real 
hardware - starting with iPhones, as I’ve got a few of these. I really don’t 
know how to do this for testing, and more so I don’t know how to distribute a 
test version to a small population of testers, although I know this is 
feasible. The whole project may crash and burn at this beta testing stage, so 
actually getting it into the App Store can wait a bit.

Obviously I am not expecting people on this list to hold my hand at every step. 
My main concern is to be guided through the body of LC notes etc to get 
absolutely practical advice and recipes as to what to do at each stage. If I 
study the LC stuff long enough, I will get there, but I would dearly love help 
to fast-track it all.

Thanks

Re: Strange times, amazing projects

[Devin Asay via use-livecode]

Skip, have you tried the Google geocoding web service? Give it an address or 
landmark, and get back latitude/longitude coordinates.

https://developers.google.com/maps/documentation/geocoding/start

Fairly simple to get into, a snap to implement in LiveCode, and free until you 
exceed a certain number of accesses.

Good afternoon LC'ers (evening to some),

Enjoyed the Zoom chat today and it was good to see all of your faces
again.  It has been way too long.

Over the past couple of years I have been sidetracked from LC as I have not
had the need to be as hands on as I once was.  Now, however, I am forced to
pull out skill sets and take on projects / challenges that I have not done
in quite some time.  Actually, it is quite exhilarating.

I won't get into details about the project as a whole right now (but I
can't wait to share it with you all when it is done) but I have a challenge
that involves mapping and coordinates and I am trying to wrap my head
around how to accomplish it.

I have delivery zones built in Google Earth and I have delivery addresses.
I need to run through the list of delivery addresses to determine which
delivery zone they fall in.  Sounds simple (or maybe not) but I can't
figure out how to work out the coordinates of the address and filter it
within the perimeter coordinates of the zone.  Hopefully I explained this
clearly.

I realize I will probably have to first run the delivery addresses against
some database that will give me GPS coordinates which I can then use
against my delivery zone kml data.

Has anybody done this before?  Any suggestions?

As always, your input is GREATLY appreciated :)

Best regards,

SKIP KIMPEL

Re: Getting started with geographical coordinates

[Devin Asay via use-livecode]

Graham,

You get back lat and long in degrees and fractions of degrees, as a decimal 
numeral. For instance, I get latitude: 40.248676 and longitude: -111.651062, 
and for good measure altitude in meters at 1398.380493. Wow, now you all know 
exactly where I am!

I am reviving my LiveCode skills in these troubled times, and I want to do

Can anyone point me in the right direction. Sorry if it’s obvious.

Hi all,

Yesterday I had to install Android mobile tools on my laptop (since I’m having 
to work from home now. I downloaded the newest JDK 1.8 and the newest Android 
Studio (v. 3.6). (LC v. 9.5.1 on Mac 10.14.6).  I spent a frustrating afternoon 
of getting an error every time I tried to specify the Android SKD root in LC 
Mobile Support preferences. Message was "The chosen folder is not a valid 
Android SDK. Please ensure you have installed it correctly, and enabled support 
for 9.0 (API 28)”. Finally after installing and reinstalling everything several 
times, I decided to drop back to Android Studio v. 3.5.3. Suddenly it was 
working again!

Re: Problem opening version 9.6.0 (dp3)

Bill,

Does this help? It was at the end of the release announcement:

Known issues

- This build (for Mac) is not notarized yet, so if your Mac is running
MacOS Catalina (10.15.x) you will get a warning dialog saying that the app
cannot be opened. In this case, you have to whitelist LiveCode in the
System Settings -> Security and Privacy, and then right-click on LiveCode
and choose "Open" from the contextual menu. Just double-clicking to open it
will not work.

Note that you'll only need to do this once, the very first time you open
LiveCode 9.6 DP-3. For more details and instructions see here:

Re: Synchronisation of sound and vision

[Devin Asay via use-livecode]

Tore,

I would agree if callbacks were 100% reliable. I have tried them in the past 
and found that in some cases they were missed. I never had any trouble when 
using time indices. But I should say that I haven’t needed to do this for 
several years, and the callbacks in the new player object might be completely 
reliable.

In other ways creating time indices makes your application more flexible, 
however. It’s dead simple, for instance, to set up an application where you can 
click on a line of text and play just that line. Set the startTime, set the 
endTime, set the playSelection to true, start playing. Done. That would be a 
little more challenging if all you had was callbacks.

One of the great things about LiveCode is that there is almost always more than 
one way to do what you want.

Regards,

Devin

You can easily handle large audio/video files using callbacks. I would

You could also store the callbacks for each audio file in a text file and set

Take a look at the duration and the timeScale properties of player objects. By

put the duration of player  “foo” / the timescale of player  “foo” into 
totalSeconds

What you are contemplating is very doable, but you’ll have to do a fair amount 
of work to do to get the synching right. You can take one of several approaches:

- Calculate times as above to predict when to show/highlight the next line. Can 
be tricky with long video files and rounding errors.

- Check the currentTime property of the player to determine the startTime and 
endTime of each spoken line, and set the playSelection of the player to true. 
When the played segment ends, immediately load the following start and end 
times and play again. Something like this, from memory:

set the startTime of player “foo” to 444
set the endTime of player “foo” to 999
set the currentTime of player “foo” to the startTime of player “foo”
set the playerSelection of player “foo” to true
start player “foo"
- Break up the video or audio file into separate files, one line per file, then 
play each succeeding file when the previous one reaches its end. The

the cues take?

Re: Do Mac OS apps stop working if your Mac Developer ID Application cert expires?

[Devin Asay via use-livecode]

I’ve done lots of test deployments to devices that are registered in my 
wildcard provisioning profile. After the cert expires the app no longer runs on 
the test devices. You have to renew the cert and provisioning profile, re-save 
and reinstall the app on the device if you want it to work again.

I don’t know if it is different if you are distributing with an app-specific 
provisioning profile, since I haven’t tried that.

Re: Primary Student Livecode Interface (Simplified Developer Interface)

[Devin Asay via use-livecode]

RIchmond has an excellent point: your development environment is less important 
than your goal.

The reason that all of us immediately typed ’set the userLevel to 5’ in 
HyperCard is that you wouldn’t get far in your task until you needed a bump-up 
to a higher level of capabilities.

I also teach beginning programming (beginning application development is 
actually a better term), but to college students rather than primary kids. I 
realized recently like a bolt of lightening that I have been spending far too 
much instruction time describing the development environment and too little on 
setting tasks and then telling the students about the tools in LC that let them 
accomplish the task. I don’t know why it took me so long to come to that 
insight, because “need-based” learning is how I learned both HyperCard and 
LiveCode. (And probably how most of us learned.) Now I’m thinking about ways to 
incorporate more task-based instruction into my classes.

But then I’m faced with the paradox that, according to some of the research 
I’ve looked at on teaching programming, large problem solving assignments are 
less effective than focused focused practice in teaching fundamental 
programming concepts. What I take from that is that students are helped by 
“drilling” a concept with canned, focused, smaller tasks than they are by 
setting them a complex problem to solve. So my evolving approach is 1. present 
a concept, 2. do some drill and practice on the concept, 3. set them a more 
complex task that requires them to apply the concept.

I had imagined by this time in my career that I’d have figured this all out. I 
might just be slow. :-)

the kids use exactly what they require and are generally self-limiting.

Re: help with mobileSetKeyboardType

[Devin Asay via use-livecode]

Dan,

I believe it’s because setting keyboard type with a mobile native control is 
done by setting a property with mobileControlSet:

mobileControlCreate "input","_editingField”
mobileControlSet “input”, “keyboardType”, “number”

The mobileSetKeyboardType command works in all other circumstances, including 
with native LiveCode fields.

No, I’m just toying with the idea of having a 32-bit launcher that would 
examine the host OS, then launch the proper executable based on whether it is 
32 or 64 bit. Sort of like a poor man’s universal app like we used to create 
for MacOS. It’s possible I’m use way overthinking this.

Checking the host OS

[Devin Asay via use-livecode]

Hi all,

I know we can get all manner of information about the host system our stack or 
application is running on, including platform(), processor(), and machine() but 
is there a way to check to see whether the host OS is 32 or 64 bit? The 
platform function on Windows always returns Win32 regardless of which version 
of Windows is running, and the processor reports x86_32 or x86_64, depending on 
the host machine’s CPU.

Now that we can build both 32 and 64 bit applications for Windows, it’s 
important to be able to tell whether the host OS is 32 or 64 bit. But I can’t 
work out if these functions let us get that information. For instance, on my 
Windows 10 64-bit system I get:

The platform: Win32
The processor: x86_64
The machine: x86_64

But I just had a user report that they were unable to run a new build of one of 
my Windows applications, which I had built as 64 bit. I’m sending them a 32-bit 
build, but I got to thinking, would there be a way to check that from within 
LiveCode?

Any ideas?

J,

I don’t think you need the slashes after file: at all. (“file:” & 
specialFolderPath(“resources”) & “/tFolder/tFile.hmtl”) should do it.

Also check case on folder and file names. Case matters in mobile file systems 
in my experience.

Re: Groups do not receive mouseEnter messages?

[Devin Asay via use-livecode]

This is  a great idea, Paul. I was just thinking that might be a good solution, 
especially with the addition of the (relatively) new clipsToRect property of 
fields. When that property is true, a group’s boundaries do not automatically 
snap to the area defined by its child objects. Instead the group’s boundaries 
remain where the developer set them. Given that groups can now have an 
arbitrarily larger area than their child objects, it makes sense that we might 
want the option of treating them more like full-fledged objects than simply a 
container for other objects.

event messages, such as if you are using a group as a drawing canvas.

Yes, wonderfully in Livecode, most things that can't be done one way, can be 
coded around to work another way.

I would suggest an enhancement to LiveCode to add a property to Groups that 
toggle between:

behave as a container: current group behavior regarding mouse event messages 
[default]
OR
behave as an object: cause the group to received mouse event message (and other 
routine object messages) following the usual rules (i.e. if there is a button 
in the group that has a mouseEnter handler it gets the message when the button 
is entered, but the group gets a message when it is entered, just as if you 
have a small button on top of a large button)

I don't know what to call the proposed property, and I certainly would not, at 
this time, prioritize it. I've submitted nearly 20 bugs in the last 60 days and 
I'd much rather see more of those fixed that a new feature added. That said, a 
property like this could be s solution for both use cases of groups.

Re: Groups do not receive mouseEnter messages?

[Devin Asay via use-livecode]

I have always thought of a group as a container object, like a card, but 
without a “canvas” that constitutes a part of the object. It’s always made 
sense to me that a group doesn’t get mouse messages, except as they are passed 
from child objects. If the group did get mouse click messages, it would 
complicate things in situations where you want to know which child object was 
clicked on.

A group of audio playback buttons, as it stands now:

on mouseUp
   play audioClip (the short name of the target)
end mouseUp

A group of audio playback buttons, as it would be if the group received mouse 
click messages:

on mouseUp
   if the owner of me is not me then
  play audioClip (the short name of the target)
   end if
end mouseUp

So at least for most of my use cases, the current situation makes the most 
sense to me.

My $.02.

I suppose as long as one knows how it works, it can be dealt with.

But there is an issue here, in that a group is not really a control, despite
what the dictionary says. A group has a rect, and one can tell if the
mouseLoc, say, is within that rect (and not necessarily within the rect of a
child control), but one cannot rely on any "ordinary" LC thinking to hold at
all.

I understand that a group is merely a group of controls. If it was a
ghostLike object that only did that, then well and good.

But since it interacts with those controls intrinsically (as, for example,
the way radio buttons behave "natively") and owns most "ordinary" control
properties, well then, dammit, if one makes it opaque and green, it ought to
respond to mouse events.

Re: finding location on mobile device

[Devin Asay via use-livecode]

This has worked for me in the past, but I haven’t tried it in quite some time:

mobileStartTrackingSensor "location", false
put mobileCurrentLocation() into tLocArray
mobileStopTrackingSensor "location"
put "lat: " & tLocArray["latitude"] & cr & "long: " & tLocArray["longitude”] 
into fld "report"

Re: How to find the offset of the last instance of a repeating character in a string?

There was a discussion on this topic on the list a few years ago, and I saved 
these functions in my script library:

From Peter Brigham:
These are utility functions I use constantly for text processing. 
Offsets(str,cntr) returns a comma-delimited list of all the offsets of str in 
ctnr. Lineoffsets(str,cntr) does the same with lineoffsets. Then you can 
interate over the list of offsets to do whatever you want to each instance of 
str in cntr. I keep them in a utility stack that is in the stackinuse, so it is 
available to all stacks. I don't use regex, as I have never gotten the regex 
syntax to stick in my head firmly enough to find it natural, and in any case 
doing it by script turns out to be as fast or faster.

Peter's lineOffsets function returns a line number for each found char offset. 
I added a function that returns only unique line numbers.

function offsets str,cntr
-- returns a comma-delimited list of
-- all the offsets of str in cntr
put "" into oList
put 0 into startPoint
repeat
put offset(str,cntr,startPoint) into os
if os = 0 then exit repeat
add os to startPoint
put startPoint & "," after oList
end repeat
if oList = "" then return "0"
return item 1 to -1 of oList
end offsets

function lineOffsetsAll str,cntr
-- returns a comma-delimited list of
-- all the lineoffsets of str in cntr
# (returns a line number for ALL instances)
put offsets(str,cntr) into charList
if charList = "0" then return "0"
put the number of items of charList into nbr
put "" into oList
repeat for each item n in charList
put the number of lines of (char 1 to n of cntr) \
& "," after oList
end repeat
return item 1 to -1 of oList
end lineOffsetsAll

# added by Devin Asay
function lineOffsets pStr,pSearchTxt
# (returns only unique line numbers)
put empty into tList
put 0 into tStartLine
repeat 
put lineOffset(pStr,pSearchTxt,tStartLine) into tLineNum
if tLineNum = 0 then exit repeat
add tLineNum to tStartLine
put tStartLine & "," after tList
end repeat
if tList is empty then return "0"
return item 1 to -1 of tList
end lineOffsets

Hope this helps.

Paragraph-level formatting opens up wholly new opportunities, beyond any xTalk

I'm not sure if this info has been incorporated into the docs system yet, but 
the Release Notes for v5.5 offer a solid overview of the new field features 
(starting on p12), most of which are paragraph-level properties like indent, 
border, padding, etc. (p19), along with the wonderfully efficient styledText 
array representation of field contents ([p16) and super-useful indented lists a 
la HTML and word processors (p18):
https://downloads.livecode.com/livecode/5_5_4/LiveCodeNotes-5_5_4.pdf

When I revised the htmlText property entry in the dictionary a couple of years 
ago, I incorporated all of the changes to the paragraph  tag, which included 
all of the new paragraph level properties. That’s the only place in the 
dictionary I can think of where a discussion of all of the p-level properties 
together is appropriate. What is still left to be done is to update all of the 
entries for the individual properties that were field-level props only before 
v. 5.5. While the syntax statements have all been updated, there is no note in 
the entries of when they were changed to become p-level. I wish I had the time 
now, but my LC time has been severely reduced by my duties at work the last 
couple of years.

Dictionary editing is a great way for community members to contribute to the LC 
project, and the barrier to entry is much lower than trying to learn enough C 
code to work on the LC engine. It requires attention to detail, but otherwise 
is kind of fun and not difficult.

LC 9 and Icon Families

[Devin Asay via use-livecode]

Hi folks,

Couldn’t resist spending some time on the new RC of LC 9. One of the cool new 
features is the ability to add icon families to your instance of LiveCode. 
Using the release notes and the dictionary I worked out how to create and add 
new icon families. This finally makes it possible to use your own custom icons 
in a Nav bar widget, for example.

Try out my stack here (enter in message box):

  go stack URL "https://asay.byu.edu/stacks/IconFamilyMaker.livecode;

Enjoy!

“Standard icons” is in an option list, and the next option on the list is 
Default Patterns. That gives you a slightly less-unusable selection of 
background patterns you can apply to your object. The feature is really more 
useful for setting an image of your choice as the background of an object. Just 
import the image and use:

set the backgroundPattern of fld 1 to 10003 # the id of the imported image

It’s not clearly indicated. Right click on the pattern box in the right column 
and choose “Reset to default”.

See above re setting the backgroundPattern. There are lots of instances where

Re: Background color in an 'answer' dialog?

[Devin Asay via use-livecode]

Graham,

I think what is happening is that when you run in the IDE the parent stack of 
the answer dialog stack is the LiveCode engine, which sets a 
platform-appropriate background color (or no background color) for all child 
stacks. When you include it in a standalone, your stack-made-standalone becomes 
the parent stack, and whatever background color is set for that stack is 
inherited by the answer dialog stack. At least I have seen this happen with 
standalones that have a stack color set, and I’m fairly certain this is what 
you’re seeing. What happens if you change your main stack’s background color 
then rebuild the standalone?

By the way, when I said my red background had disappeared, it hadn’t. It’s just 
that when you I through the script in the IDE, the background comes up white, 
whereas in the standalone (both platforms), it comes up red. A bug, surely? I 
will see if I can boil it down far enough to report it.

As a follow-up, is there anywhere a list of all IDE stacks? For example, the

It is a great way to get oneself in real trouble, but also useful if one
wants red answer dialog boxes.

put revOpenDatabase(“mysql”, tServer, tDatabaseName, tUser, tPass,true,,,true)

Re: LiveCode University bug

[Devin Asay via use-livecode]

Andrew,

It’s best just to send them to me; avoids the middleman. :)

I’m in the final stages of creating an updated version that uses much more 
up-to-date content. Perhaps I can send you a “DP” status copy and have you take 
a look at it. I think it’s in pretty good shape except for a final, nagging 
content update bug that I expect to swat this week.

Regards,

Devin

I'm getting ready to start a new semester teaching LiveCode using LiveCode 
University. Each time I run this class, I notice some discrepancies between LCU 
and whatever the current version of LC is. Devin Asay is listed as the author, 
but this was purchased through RunRev. I started to file a bug report at 
quality.livecode.com and realized that probably 
isn't the right channel.

Who should bugs be reported to for LiveCode University?

Re: SQL Insert Syntax

[Devin Asay via use-livecode]

Bob,

You could try parameterizing your statements as described in the dictionary. 
Also, you don’t want to quote your column names.

put 0,43,500,543 into tRect
put “image “ & quote & “fresh_now.png” & quote into tObj
put “card “ & quote & “Main” & quote into tCard
put false into tVis
revExecuteSQL myID, "insert into arraydata (rect,controlname,owner,visible) 
values(:1,:2,:3,:4)", “tRect" ,”tObj”,”tCard”, “tVis”

This is also best practice, because it protects against SQL injection attacks. 
(Admittedly more of a concern with network databases.)

HTH

Re: SQL Insert Syntax

Bob,

Some SQL dialects accept both single and double quotes as string delimiters. 
Might that be the problem?

Can anyone find anything wrong with this sqLite insert statement?

INSERT INTO arraydata ("rect","controlname","owner","visible") VALUES 
('0,43,500,543','image "fresh_snow.png"','card "Main"','false')

It doesn't generate an error, but neither does it insert anything! There is a 
primary key column that I don't include because it's supposed to auto increment 
automatically if no column/value is supplied.

Re: Simulator woes

[Devin Asay via use-livecode]

Thanks, Paul. I did finally get it working, using the old standby—deleting 
LiveCode preferences and then restarting the simulator. Wish I’d thought to try 
that combination earlier. Thanks for your suggestions.

Devin,

I did just see the same error when launching the simulator for the first time 
(this session), but then I restarted the simulator device and all worked as 
expected, but it was a long laborious process displaying multiple messages.

One trick I’ve used in the past still worked OK. When the simulator does 
finally open, add it’s icon to the dock, now when working on a mobile apps, 
launch the simulator from the dock first, when it does open fully any tests 
sent to the simulator from LC are opened much quicker

LC 9.0.0 (dp11)
Xcode 9.2
Mac OS Sierra 10.13.2

Has something changed?

When I try to test a stack in the simulator I get the “taking a long time to

message “Unable to start simulation: Simulator session timed out.” This happens 
whether or not the simulator is launched when I hit the Test button in LiveCode.

I’ve tried several different versions of LC and Xcode. All the same result. 
Right now I’m on:

Mac OS 10.12.6
LiveCode 9.0.0 DP 11
Xcode 9.2

Is this a new problem that others are seeing? I’m not finding anything in the 
forums, and have a vague memory of a discussion here about this topic. Any help 
greatly appreciated.

Re: ArrayToJSON in LCServer ?

[Devin Asay via use-livecode]

Alex,

My recollection is that for functions in libraries, like this one, you have to 
find the library stack in the IDE installation and copy it to your server then 
‘start using’ it, in the case of a stack, or ‘include’ it in the case of a .lc 
script. (The former is what I’ve done, I believe.) I’ve done this successfully. 
The hard part is figuring out where the library is stashed in the IDE 
installation.

That can't be right - can it ?

Must be something I need to do - but what ?


(*) The dictionary for the array <-> JSON functions don't mention OS or 
Platforms.

My simple test script could be much simpler ...
