[Paul Hibbert]

How can a major UK Mac magazine ignore LiveCode in an article titled "Complete 
guide to coding and programming on a Mac: Best programming languages for Mac 
coders | How to get started as an app developer”.

Link: 
http://www.macworld.co.uk/how-to/mac/complete-guide-coding-programming-apps-mac-3645777/

I’ve left a comment on their page, may help with a few more comments.

If I'd kept using it another year, I'd probably be wealthy now--I had no
clue that the DOS version was actually going to ship in another year, and
dropped my project.

*sigh*

I last used 1.5 . . . but a couple of years ago, I *was* able to import the
stacks to the trial version of the then-current version (4.5?).  I had to
drag out an old MacClassic, restore from a stack of backup disks (an
adventure in itself, finding a copy of the backup program), write to
floppy, convince a FreeBSD machine to read that, and then either burn a cd
or use a usb to get it onto a modern mac . . .

using Sierra

[Dr. Hawkins]

The shared iCloud drive was compelling enough for me to convert to Sierra
without waiting months.  It does a *far* better drive at syncing than Wuala
used to or than SpiderOak does, and without churning cpu and battery on my
laptops.  (pretty much 100% cpu whenever on, and still doesn't finish
updates).

Anyway, I'm noting that scrolling from the magic trackpad seems quirky in
LC 7.

At times, it scrolls insanely fast, and at times it doesn't seem to refocus
properly--eg, in the panes of the application browser.

Are other people seeing the same?

Re: Recursive Script

[Paul Dupuis]

Here is an example:

function listDatagrids pObject
  local dataGridList
  repeat with i=1 to the number of groups of pObject
if grp i of pObject is a datagrid then -- fix this line
  put whatever data on the datagrid & return after dataGridList --
fix this line
else
  put listDataGrids(long ID of grp i of pObject) into childList
  if childList is not empty then put childList & return after
dataGridList
end if
  end repeat
  return dataGridList
end listDataGrids

there are 2 lines you need to fix - one is how to tell a grp is a
datagrid. I recall a property or API you can check, but didn't have the
datagrid PDF handy.
The other is whatever info (short name, long ID, etc. you want for each
datagrid

Call it with the long id of the card. As in:

put listDatagrids(long id of cd x of stack y) into myListOfDatagrids

Re: use "" as an array key

[Bob Sneidar]

sqlYoga handles sql NULL by converting them to the string "NULL". When writing 
back to the table it handles that too. the difference in where clauses is that 
you cannot use equal (=) as an operator. You have to use "is". Also I think in 
an insert or update statement in the set clause you have to use the NULL 
constant and not enclose in single quotes 'NULL' which would be the string.

Being able to use it as an array key is important for being able to
represent real-world data in an array.

It's an important point that "", a 0 character string is not the same
as NULL because we as humans often 'see them' as the same.

Very confusingly, "null" in LiveCode Script is _not_ the same as "NULL" in SQL.

In LiveCode, "null" is shorthand for "numtochar(0)".

LiveCode Script doesn't really have the concept of "no value at all" that is 
modelled by SQL's "NULL".  Most of the syntax fakes it by using the empty 
string, but unfortunately that doesn't work everywhere.

LiveCode Builder has "nothing", which is a proper "no value".

Issues with 'Open Recent File' on LC 8.1.1rc1

[Graham Samuel]

My list of recent files should include a stack I’m working on which I keep in 
DropBox (as is usual, there’s a local copy  of this file on my Mac). But the 
name of this file tends to disappear from the ‘Recent Files’ list, whereas 
stuff that dates back many previous versions of LC is still there, including 
strangely something that was in DropBox several versions ago. This may be a 
bug, but I have not yet got a recipe.

Is anyone else experiencing this? I can’t see anything relevant in the bug 
database.

Recursive Script

[Bob Sneidar]

Hi all. 

Some time back someone had the need to enumerate every datagrid on a card even 
if the datagrids were themselves grouped with other objects. I cannot now find 
that thread, or any stack treating the issue in my downloads folder. It would 
involve recursion because the groupnames is a property of a card and not 
another group. If groups had the groupname properties it would be easy. 

As it is I then have to enumerate all groups and do recursive calls passing the 
current group as the next group to enumerate. If none of that makes sense just 
think, "42". 

My trouble is I am having a difficult time formulating the recursive function, 
and I cannot find recursion anywhere in the Livecode Lessons. I need an example 
of a recursive function.

Re: very often "Scripts externally modified" popup

This sounds like what I was running into where a handler didn't work until I 
copied the text of the script into a text only editor, then copied it back into 
the script. I know there was a difference because after pasting I had to 
recompile. If the scripts are identical you will not get the dirty flag.

Just FYI, mobileLockIdleTimer will prevent the device locking and
turning off the screen, which is a real battery killer. A mobile device
can play audio with the screen off for many, many hours. Of course if
you actually need the screen on, no problem.

On iOS, assuming you have the audio background mode set (in the
info.plist), the device doesn't suspend your app while it's still
playing audio. It may be the case that the way LiveCode works with audio
APIs, or the way you're using them, means you stop playing between
tracks for too long, so the system assumes the audio is finished. Might
be worth further investigation.

Re: Wondering about iOS background tasks

[hlowe]

Bill,

iOS supports local notifications (as supposed to remote notifications) that
work even if the app that created them is no longer running. See:

https://developer.apple.com/library/content/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/Chapters/WhatAreRemoteNotif.html

Basically the app creates a local (device) time-based notification and
registers it with iOS using the LC command 'CreateNewMobileNotification'. 
When the local notification date and time arrives iOS will send the
notification back to the app that created it. If the app is not running iOS
will issue a notification alert to the user, providing the option to
automatically launch the app. In LC the app receives a
'localNotificationReceived' message that includes information about the
notification. The app handles this message (and its associated data) to
process the notification alert.
