No 'the processor' reports what architecture the engine was built for. 
From the dictionary:



Use the processor function to determine the system architecture. The 
system architecture may either be emulated or the architecture of the 
host CPU. For example, when running the application in an android 
emulator the processor will return the emulated architecture rather than 
the architecture of the host CPU.


Note: Some operating systems have emulators built in. For example, 
Windows has WOW64 which allows x86 executables to run under x86_64 
versions of Windows.

it's more than the zero tutorials we've had on it thus far:

Interesting, and as you say, a good start can be made easily. But it has 
many built-in assumption that may come back to bite you 


on resizeControl -- Allow the user to enjoy whichever orientation -- 
they prefer with responsive design: -- put item 1 of the loc of me 
into tMidX put item 2 of the loc of me into tMidY -- if the width of 
this cd < the height of this cd then -- Portrait: set the loc of grp 
"UserInfo" to \ tMidX, tMidY - (the formattedHeight of grp "UserInfo" 
div 2) set the loc of grp "MembershipInfo" to \ tMidX, tMidY + (the 
formattedHeight of grp "MembershipInfo" div 2) else -- Landscape: set 
the loc of grp "UserInfo" to \ tMidX - (the formattedWidth of grp 
"UserInfo" div 2), tMidY set the loc of grp "MembershipInfo" to \ 
tMidX + (the formattedWidth of grp "MembershipInfo" div 2), tMidY end 
if -- end resizeControl
In Portrait mode, this assumes that the two groups are the same height 
(or nearly so). If they're not, one or other of them will finish up 
bumping against the top (or bottom) of the card.


Similarly, in Landscape, it assumes they are same-ish width, otherwise 
one of them will stick out the side.
*AND* it assumes they are the same height, otherwise the tops will be 
mis-aligned and potentially ugly.

( you could add lines like
put the min(top of grp "MembershipInfo", the top of grp "Userinfo") into 
temp if temp < the top of me + 10 then put the top of me + 10 into temp 
set the top of grp "MembershipInfo" to temp set the top of grp 
"UserInfo" to temp


to the end of the Landscape case).

And there are other assumptions

1. the fields are sized suitable to fit in the width of the narrowest 
device. If a narrow device is small enough, maybe the labels should 
slide around to above its field, rather than be beside it.


2. assumes that you don't want to widen the fields on not-very-narrow 
devices - whether stretching the fields, or increasing spacing between them.


3. In landscape, there may well not be enough width to allow the two 
groups side-by-side (say, on a phone), and you would really prefer to 
have the stacked vertically, even though in Landscape.


4. (perhaps the hardest) if you have text areas (i.e. multi-line 
fields), how do you decide whether to expand vertically depending on the 
height of the card, versus simply allowing vertical scroll bars within 
the field.



In summary - I absolutely agree that LC has everything needed to provide 
responsive layouts, and that with even a modicum of effort (which might 
seem tedious the first few times :-), it can produce layouts which are 
MUCH more responsive than a typical web page/app. But there is a danger 
of thinking it is too easy, and producing semi-responsive designs which 
are not quite good enough.


Things that would help:

1. either a widget or a compound-control for labelled field which wold 
allow the encapsulation for the sizing options for label+field; and 
would allow for labelling above or beside the field depending on 
context, space available and kind of field.


And there are others -library functions or behaviours that will help 
with the common cases - more thought on that tomorrow.


Alex.

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

2020-04-27 Thread 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?

The version almost uniquely identifies every public engine build - the

The platform together with the processor uniquely identify the target it was

As of LC 9.6.0 (dp4) there is support for detecting whether the system is in 
dark or light mode and also a message that signals when the display mode 
changes. This works well and we have successfully added dark mode support to 
our iOS app. However, there appears to be no support for adding a light & dark

bright light mode start up screen. Different dark and light mode startup 
screens are supported by Xcode’s storyboards, which will soon be mandated by 
Apple as the only way to support iOS launch screens. Any idea when this support 
might be available? We were hoping to release an update to our iOS app 
implementing dark mode, as this is a much requested feature, but are now

Is it all that tedious?

Computers have had resizable windows since Mac 1.0, and even HyperCard
stacks could be resize after its first version.

True, in the very olden days we all enjoyed the simplicity of knowing we
never had to accommodate any screen size other than 512x342.  Ah, those
were the days! :)

But 640x480 came along not long after, and it caused much concern among
developers. Suddenly we had to become aware of screen metrics, and
rearrange our layouts to make good use of the available space.

Then 1024x768 came along, and then we had THREE(!) screen sizes to
contend with. Oh the humanity! :)

Then by the early 90s we got over it.  Anticipating multiple screen
sizes became the norm, new tools like SuperCard, OMO, and MetaCard came
along offering true resizable windows, and we learned to respond to
notification that the window had resized so we can adjust our interior
contents nicely.

Flash forward to 2010: iPhone comes out, with the presumption that one
size will satisfy all tastes.  That didn't last long.  History doesn't
always repeat itself, but it often rhymes. :)



As with desktop software, I find it instructive to observe how the best
apps on mobile behave, and then - because those establish user
expectations - do what they do.

And what we see is not all that different from how designers handle
resizable windows on the desktop: some objects stay where they are,
those that make sense to enlarge enlarge, those that make sense to
remain adjacent to something next to them remain adjacent to something
next to them, etc.

If you've written resizeStack handlers at any point in the last 28 years
since MC premiered, you've already learned most of what you need to know
to handle a resizeStack message on a mobile device.

The specifics of how this plays out in your layout will of course depend
entirely on your layout.  But I have found a few things that have
greatly simplified my UI work, chiefly:

- Use Groups Smartly

Relatively recently (a few years ago) the engine now sends a
resizeControl message to groups whenever they're resized by any means,
either user interaction with the pointer tool (as had always been the
case) or via script (the new addition).

This allows us to work with our UIs very cleanly, recognizing that an
app is ultimately a set of rows, and that some rows are divided into
blocks.  When we group controls by their location/purpose logically, we
get to take advantage of a wonderfully simplifying cascading effect with
regard to resizing, which allows us to keep control adjustments local to
their containing group.

Imagine a simple message form, where the rows are:

- Icons for navigating to different screens

- Message, which includes three rows:
   - Subject field
   - Body field
   - Send button

With that, our card script need only bother itself with the general
placement of the two main goups:

on resizeStack x,y
set the rect of grp "Nav" to 0,0,x,40
set the rect of grp "Message" to 0,40,x,y
end resizeStack

And because the groups will get a resizeControl message when that card
script adjust them, each can contain its own handler to take care of its
interior contents.  This might be the script for the Message group:

on resizeControl
set the rect of fld "Subject" to the left of me, the top of me, \
  the right of

ScriptTracker isn’t necessarily incompatible with Levure, but if using that

behaviors which would make it unnecessary.

I have thought about setting up a hybrid project as a test but never have

RE: Counting unique items in a file

I would change the first line below and add one line and one 
parameter(dateTimeColumn). This assumes that the date/time is converted into 
seconds or milliseconds).

add 1 to uNames[item pColumn of l]["Count"]
if item dateTimeColumn of l > uNames[item pColumn of l]["DateTime"] then put 
item dateTimeColumn of l into uNames[item pColumn of l]["DateTime"]

Then the returned array will still have the keys of all unique drivers and each 
key will have 2 keys "Count" and "Datetime"

mouseColor randomly returning "0,0,0"

2020-04-27 Thread Richard Gaskin via use-livecode
For years I've relied on the mouseColor to pick up colors for my 
layouts, but lately I've found something weird:


Most of the time it works, but sometimes it return "0,0,0" over things I 
know aren't black.


For example, this morning it's returning that color of a large block of 
solid light green.


Has anyone else seen oddities with the mousecolor?


Current test environment: LC 9.6dp4, Ubuntu 18.04

Skip,

Haven't tested, but pope about this...

function getUniqueNames inData,pColumn
  put "" into uNames
  set the itemDel to tab
  repeat for each line l in inData
add 1 to uNames[item pColumn of l]
  end repeat
  
  return uNames
end getUniqueNames

You should get back an array keyed by the unique names, and how many instances 
of each one

Re: How to make a mobile app stay alive in the background?

2020-04-27 Thread Graham Samuel via use-livecode
Panos, as usual, this is terrific information! I am applying your advice 
immediately.

Not to start an argument, the statistics you quote don’t accord with my 
personal experience. Almost everyone I know who owns Apple kit has at least one 
phone or iPad that can’t be upgraded to the latest OS version - and these 
devices still work well. In our house for example there are three iPhones, only 
one of which can run 13.x; two iPads, one newish one and another which is back 
at iOS 9 I think (still works for email and browsing, at any rate). However, to 
be practical I will  do as you suggest with my own app.

Thanks for your continued interest in these issues.

Graham

Maybe. The list may be expecting different line endings than AOL provides. What 
we usually see 
when people paste here from the SE is a bunch of markup symbols, but the 
carriage returns 
generally come through okay.

Here's a copy/paste test from my LC editor, let's see what happens:

Re: How to make a mobile app stay alive in the background?

2020-04-27 Thread panagiotis merakos via use-livecode
Hello Graham,

I could not find any *official* source from Apple, as their docs are
scattered around and it is not easy to determine always if a document is
out of date, but from what I understand iOS apps are running in the
background by default since iOS 12+. Given how quickly people are moving
(or forced to move) to using the latest iOS versions, I would not worry if
my app (in the AppStore) only covered iOS 12+:

iOS version stats: (from https://david-smith.org/iosversionstats/)

13.X --> 92.5%
12.X --> 5.1%
11.X --> 0.7%
10.X --> 0.7%
9.X --> 1.0%

For your use case, I think this should work:

- Use LC 9.5.1 and check "Enable Background Execution" and "Location
Updates" in the background modes in the iOS settings. This should allow
your app to receive the "locationChanged" msg even when in background. Then
use an ad-hoc distribution profile to sign your app and deliver it to
specific devices (including pre-ios12) to get some feedback

- When you are ready for publishing the app to the AppStore, just rebuild
it with LC 9.6, using an AppStore distribution profile, and upload it to
the AppStore. You will be able to deliver it to some beta testers via
TestFlight at this point (running iOS 12+)

Hope this helps.

Kind regards,
Panos

Re: How to make a mobile app stay alive in the background?

2020-04-27 Thread Graham Samuel via use-livecode
Panos, thanks for that info. The truth is my particular app has proved such a 
challenge for me in so many different ways that it may never reach its intended 
user population - but on the off-chance that I do finish it, then I think I may 
have to get involved with the Apple App Store, if only to use TestFlight to get 
it out to quite a lot of people. So maybe my announcement at that point will be 
that if your phone only runs earlier versions of iOS, sorry it won’t work 
unless you are willing to use it without ever letting the app go into the 
background - something very awkward in practice if you’re walking for an hour, 
which is what first use is all about. Can you say what is the lowest version of 
iOS is that would allow background working without a problem? Right now in my 
other test device I’m running iOS 13, which must be OK, but are there others, 
11.x and 12. x that would be OK?

Having asked that, please note that ‘running in the background’ seems to mean 
different things to different people, but to me it means continuing to receive 
sensor data while in the background, since as far as I know, such data would be 
unrecoverable if not collected in real time. A good example would be working 
out how far a person has walked. This can only be done by accumulating 
increments of change of location (via GPS) without any serious gaps, so data 
acquisition has to be continuous. There are lots of other examples, specially 
if we’re allowing Bluetooth connected sensors.

Just for completeness I should say that I have asked LC Support to explain 
commands like mergBgTask, as the available documentation does not give examples 
etc. and really does not help the newbie in this area.

Hello all,

Just to add to the discussion that one of Graham's phones runs iOS 10.x, so
in this case, if you need your app to continue running in the background,
you do need to build it with 9.5.1 and check the "enable background
execution" checkbox in the iOS settings. However, you will not be able to
submit this build to the AppStore, as Apple no longer accepts applications
that have this key that is added to the plist if you check "Enable
Background execution". Devices running newer iOS versions will   allow apps
running in the background anyway, so you do not need this key in the plist
- and this is why this key (i.e. the checkbox) was removed in LC 9.6 DP-3.

So, to conclude, given that you are not interested in submitting the app to
the AppStore, I believe you can include this key to the plist (i.e. check
"Enable Background Execution" checkbox), so your app will continue running
in the background in both old and new iOS devices.

Kind regards,
Panos

Thanks Jacque and Mark - very interesting! Your messages told me stuff I did 
not know. mergBgTask looks scary and somewhat unsure of itself, but i’ll try.

What is happening to me is that the app is suspended and effectively stopped 
when it goes into the background. From this state it can only be relaunched, 
showing the splash screen which I had to provide to iOS (this is not a card in 
my stack, just a PNG file insisted on by Apple), so the user does not perceive 
the app to be resuming, but rather restarting. I want them to see the screen 
they last saw when the app was in the foreground. Plenty of apps do this - 
Strava, FitDigits, etc. More importantly they do continue to actually run in 
the background, so that there are for example no gaps in the sensor records 
they are displaying, either via Bluetooth (Heart Rate Monitors for example) or 
direct via the OS (GPS information). I need that facility or my app is dead in 
the water. I don’t have trouble restoring the  app’s status on a restart, as I 
keep updating the status and storing it in the cache area of my app - but that 
doesn’t help with the continuous-monitoring-in-the-background requirement.

BTW, Jacque you said

> You are probably running an older version of LC since that checkbox has been

Perhaps in the latest DP, but it’s there in the latest official version, 9.5.1, 
at least in Indy, which I use.

Will keep trying.

Basically you have to save the user state repeatedly whenever anything
significant changes, in case the app goes dormant.


You actually need to do this regardless of having suspend/resume 
messages as there's no guarantee that (1) you will get them and (2) you 
will be able to execute them long enough to save all current state.


Both mergBgTask and mergNotify provide features to enable managing the 
background task feature of iOS, and the suspend/resume notifications 
though.


Warmest Regards

Mark.

If there is only a single instance, you could:

  replace "(x)" with "(" & someNumber & ")" in myString

If there is more than one instance then each instance would need a unique character inside the 
parentheses.

Maybe. The list may be expecting different line endings than AOL provides. What we usually see

You are probably running an older version of LC since that checkbox has been removed recently. 
iOS now runs all apps in the background, much as Android always has, and if you use that 
checkbox now the App Store will reject your app. The deal is, the OS will keep the app in the 
background until it needs RAM for something else and then it dumps the app. There's no telling 
when that will happen.


This came up yesterday in the forums. The poster wanted his app *not* to run in the background 
after a certain amount of time. We get no messages once the app goes into the background, the 
only message sent is "shutdown" when the app gets wiped by the OS. In the meantime, the app 
becomes inactive if it isn't frontmost.


Other apps seem to be able to manage this better, so it seems there's something available that 
LC doesn't support.


The imperfect workaround, such as it is, is to write everything to disk that the app might 
possibly need if it suddenly stops. When it comes to the front again, reload everything and 
carry on (you'll get an openstack message when that happens.) For example, if your app has a 
login screen then you'd need to store the credentials on disk and automatically log the user in 
when the app restarts. Provide a "log out" button so they can quit on purpose; it would delete 
the credentials from disk so they'd need to log in again next time.


Basically you have to save the user state repeatedly whenever anything significant changes, in 
case the app goes dormant.
