Paul,

I have somewhere a stack demonstrating how to use a second datagrid

with the main datagrid when the rows are scrolled.

If you may interested I can share it.




Very interested!

Given everyone's responses, I was just about to code something up myself 
using two Datagids for consistency in user interface.


Thank you!

specialFolderPath, Microsoft Window, and 64 bits

[Paul Dupuis via use-livecode]

On Windows, the SpecialFolderPath function can use Constant Special Item 
ID List (CSIDL) values, but since Windows Vista, developer were supposed 
to switch to using the Microsoft Known Folder ID system instead (I just 
learned this, so there's that!) (see 
https://docs.microsoft.com/en-us/windows/win32/shell/knownfolderid)


Under CSIDL, specialFolderPath("38") is the equivalent of 
CSIDL_PROGRAM_FILES or C:\Program Files\ on older systems or C:\Program 
Files (x86)\ on Windows 8 or 10 (for 32 bit apps)


Under KNOWNFOLDERID, this is FOLDERID_ProgramFiles and there is a 
seconds KNOWNFOLDERID, FOLDERID_ProgramFilesX64 that on 64 bit Window 8 
and 10 gets you the 64 bit app installation folder, typically C:\Program 
Files\



Under LiveCode 9.x.x (up to 9.6.0dp3) I can see no way to obtain the 
64bit application installation folder using SpecialFolderPath? Does 
anyone know if this is correct or am I missing something?


And does anyone know if LC plans to update the specialFolderPath 
function on Windows to use KNOWNFOLDERID? Or if it currently uses 
KNOWNFOLDERID (for all I know).



My use case is that I need to check both the 32 bit app installation 
folder and the 64 bit app installation folder to see if a particular app 
is installed (either the 32 or 64 bit version could be present) and I 
would rather NOT hard code the paths since we do run into non-standard 
installations among our customer base.

Is your app running as 32-bit?

Just to note (looking at the MSDN reference you mentioned):

FOLDERID_ProgramFilesX64
This value is not supported on 32-bit operating systems. It also is 
not supported for 32-bit applications running on 64-bit operating 
systems. Attempting to use FOLDERID_ProgramFilesX64 in either 
situation results in an error. See Remarks for more information.


So even if we did move to FOLDERIDs it wouldn't make much difference 
if the app is 32-bit as 32-bit apps won't return 64-bit related OS 
paths (it seems).


If the app is running as 64-bit then I think the relevant CSIDLs 
return the right thing?


Warmest Regards,

Mark.



Okay, I was running LC960dp3 (32 bit) so I downloaded LC960dp2 (64 bit) 
[I chose dp2 only because I didn't want 32 and 64 bits of the same 
version installed in case of some unknown conflict). Reran my paths test 
and your DO get different results!


Most interestingly:
specialFolderPath(38) = C:/Program Files is the 64 bot applications folder
and
specialFolderPath(42) = C:/Program Files (x86) is teh 32 bit 
applications folder


So, if I am using LC to build a Windows 64 bit standalone that 64 bit 
standalone can get BOTH the 64 bit Programs folder path AND the 32 bit 
Program folders path to check for the presence of a 3rd party 
application that could be installed as either 32 or 64 bit.


HOWEVER, if I have built a 32-Bit LC standalone, that can not get the 
path for the 64 bit Programs folder. It can ONLY get the path for the 32 
bit Programs folder


A little disappointing. My use case remains. My app (currently 32 bit)  
needs to check if a 3rd party app is installed. That 3rd party app could 
be have either a 32 bit version or a 64 bit version installed. I would 
like to use some sort of "specialFolderPath" precisely so it a user has 
a non standard installation I get the correct paths.


In at least one actual customer instance we have - out customer is 
running our app on a Microsoft Terminal Server and users get a remote 
desktop access to the server to run our app. In this specific case, 
REGISTRY queries get the users local registery on the CLIENT, but PATH

that exe with my app and called it from within LC. In your case you would

AW: specialFolderPath, Microsoft Window, and 64 bits

[Paul Dupuis via use-livecode]

So, I think I may have answered by own question.

IF my app is 32 bit THEN
   specialFolderPath(38) returns the 32 bit app folder (C:\Program 
Files (x86)\)

  and
   specialFolderPath(42) returns the 32 bit app folder (C:\Program 
Files (x86)\)


IF my app is 64 bit THEN
   specialFolderPath(38) returns the 64 bit app folder (C:\Program Files\)
  and
   specialFolderPath(42) returns the 32 bit app folder (C:\Program 
Files (x86)\)


I don't want to change to building a 64-bit Windows version of my - 
mostly because we are just not geared up to QA test for that and 32 bit 
builds.


My main concerns is where the Window OS is installed to a not standard 
volume, so you have something like:


D:\Program Files\
or
\\system07\C$\Program Files\
or
etc.

However, I can write a custom function to get the 32 bit path 
(C:\Program Files (x86)\) and take everything before "Program Files" as 
the VOLUME\ or \\SERVER\VOLUME\ and just put it in front of the 64 bit 
Program Files folder name to get a correct 64 bit path.


I don't believe that the 64bit Program Files and 32 Bit Program Files 
folders can be on different volumes.


Both Mark and Trevor's suggestions of Shell environment variables OR LCB 
wrapped windows API) (respectively) potentially offer a more stable and 
reliable solution that my thought above and I'll look into them.


Thank you all who responded.

Answer dialog enhancement...

[Paul Dupuis via use-livecode]

Here is another attempt to not reinvent the wheel:

We, like a lot of people, use:

answer [/iconType/]/prompt/[with/button1/[or/buttons/]] 
[titled/windowTitle/] [as sheet]


And we use the various iconTypes to who error, warning, or informational 
icons. We have a lot of these that are caution dialogs (are you sure 
that... sort of thing). We'd like to move to the (now) common UI 
convention of having a "Do not show this again." check box in the dialog 
combined with a set of saved preferences for whether the used indicated 
it should not be shown again. We already have a preferences system in place.


I am seeking if someone has already written code to ADD a "Do not ask 
this again." check box to the existing Answer Dialog, so you could do 
something like:


DontShowAgain "on"
answer warning "Are you sure you want to quit before saving?" with 
"Save" or "Quit" titled "Are You Sure?"

put it into tResponse
put line x of the dalogData into tDontShowAgain
DontShowAgain "off"

where a handler DontShowAgain creates and positions a check box in the 
existing Answer Dialog and adds a script to put the result in the 
dialogData (or some means to check it afterwards)


Alternatively, if no one has glued this onto the existing Answer Dialog 
has anyone created a custom Answer Dialog with a Do Not Show Again check 
box that has the same general capabilities (icon type by platform 
(Win/OSX), html text prompts, named buttons, and windowTitle as parameters)

Yes. That is easy enough. Turn on "Show IDE Stacks in List" from the 
"View" menu and there are the Answer and Ask Dialogs.


Then you need to work out how the Answer command passes its data via 
"the dialogData" property into order to create an alternative calling 
routine that sets up the Don't Ask Again check box


You could copy the Answer to your own project  and in the Standalone 
Settings switch to Manual Inclusions and exclude the Answer Dialog. Then 
I believe the answer command will use the copy of the dialog in your 
project. Then you need to add the button, change the resizeStack 
handlers accordingly, script its show and hide, add code to get the 
return value


AND remember to see if the dialog needs updates with each new release of 
LiveCode.


That is why I asked if anyone has already done it so as to not re-invent 
the wheel.

I'm thinking that if I need to roll my own, then my approach might be to 
write a handler that adds or removes the button by script from the 
standard Answer Dialog. That was if LC Corporate every makes changed to 
the dialog, your project inherits them with a new built under a new 
version of the engine.


If you copy the dialog, then you either need to rename it and maintain 
it or do manual Inclusions and exclude the engine from conflicting with 
your copy.


I was thinking something like:

on mouseUp
  dontaskagain "on","Do not show this message again."
  answer warning "Some message I may not want to see again." with 
"Cancel" or "OK" titled "A Message"

  put it into tAnswer
  dontaskagain "off"
end mouseUp

command dontaskagain pActivate, pLabel
  -- usage:
  -- dontaskagain "on|off" [, ]
  --   dontaskagain "on","Do not show this message again."
  --   answer warning "Some message I may not want to see again." with 
"Cancel" or "OK" titled "A Message"

  --   put it into tAnswer
  --   dontaskagain "off"

  switch pActivate
    case "on"
  -- setup the templateButton
  set the style of the templateButton to "checkbox"
  set the label of the templateButton to pLabel
  set the width of the templateButton to the formattedWidth of the 
templateButton

  set the height of the templateButton to 23
  --
  create btn "DontAskAgain" in cd 1 of stack "Answer Dialog"
  --
  reset the templateButton
  break
    case "off"
  delete btn "DontAskAgain" of cd 1 of stack "Answer Dialog"
  break
  end switch
end dontaskagain

This adds the checkbox or removes it to the built in Answer Dialog 
dynamically. The problem is pre-positioning the checkbox. The dialog has 
a preOpenCard handler that does the position and if I position it ahead 
of time the code it the preOpenCard changes things


I think I need to insert a openCard handler into the stack dynamically, 
which would execute after preOpenCard, that positions the check box OR


attach a behavior script with an "after preOpenCard" handler, but I 
don't understand exactly how to do that??

AW: Answer dialog enhancement...

[Paul Dupuis via use-livecode]

So I have a working mechanism to add a "Don't Ask Again" check box to 
the existing standard Answer Dialog on the fly. I offer it up to the 
community for anyone who needs it and for anyone who may want to improve 
the code. The scripts are below. There is a sample usage you can place 
in a clickable button and below that is a BEHAVIOR script that must be 
in button whose name matches what is used in the clickable button.


This is the first time I have really found a use for the "before" and 
"after" handlers. What a great addition to LiveCode!


Essentially, I add a behavior to the card of the standard "Answer 
Dialog" that positions and cleans up the Don't Ask Again check box AFTER 
the proOpenCard handler has positioned everything else AND a BEFORE 
mouseUp handler to trap clicks for changing the checkbox hilite that 
would otherwise close the dialog and return a clicked button name.


I needed to set a number of properties for the checkbox because the 
preOpenCard treats ANY button in the Answer Dialog like regular buttons 
and hides those not in use by making them 1px in size and moving them 
off screen. I may not have needed to change every property I did, but I 
didn't have the time to go through the Answer Dialog card script to 
determine exactly what properties those scripts were changing that I 
needed to reset.


I think it would be great in LC, Ltd. could fold this into the standard 
'answer' command some how.

Apple is absolutely working towards iOS and macOS being highly similar. 
However, if you're hoping that brings increased simplicity of

them of unification is to get macOS app into the same exclusivity an app 
store as iOS. Currently deployment of macOS apps can be through the 
macOS App store or outside of it. iOS app must be through the App store. 
Apple wants to gradually migrate the macOS base to the point where they 
can say macOS apps will only be available through the App store as well. 
Then they can drive the same developer changes on OSX that they do on 
iOS and take their same 30% cut.

OT: How to graph a specific data set?

[Paul Dupuis via use-livecode]

This is NOT a "How to do this in LiveCode" question.

I have a data set (below), produced by a LiveCode program and the data 
is exported to Excel.


I am trying to figure out:

1) What the "best" style of graph to visualize this data is? I thought 
perhaps a "Bubble Chart" but  - in Excel at least - does not seem to 
work for this data.



2) After determining the "best" chart style is, what charting tool (if 
not Excel) can generate that style of chart for this data?


Any tips anyone may have would be very welcome.

The data set is below. This shows that "A" intersects with B once and C 
intersects with J 4 times (as example of how to read the data). I have 
replaced the actual labels (text strings for rows and columns) with the 
English alphabet for simplicity.

I am trying to visually call attention to those intersections with high

However, the labels that I replaced with the alphabet for

may equally be fascinated when a pair has NO intersections in the data.

I need some DataGrid performance help

[Paul Dupuis via use-livecode]

I have a datagid operation that should be fast that is taking a long 
time and I don't understand why.


I use a datagrid to display a table of data as part of an analysis. The 
columns are file names and the rows are selected phrases found in those 
files. The first column is the list of phrases (162 in this example). 
The remaining columns are all the file name (254 in this example). So 
each cell (2 to 254) represents a count of the number of times the 
phrase (in column 1 of the row) was found the the file that column 
represents.


I have the following code:

  set the dgColumnWidth[tRowColumnName]  of grp 
"rwMatrixObj_DataGrid" to 200
  set the dgColumnAlignment[tRowColumnName]  of grp 
"rwMatrixObj_DataGrid" to "left"
  set the dgColumnSortType[tRowColumnName]   of grp 
"rwMatrixObj_DataGrid" to "text"
  set the dgColumnIsEditable[tRowColumnName] of grp 
"rwMatrixObj_DataGrid" to false

  repeat with i=2 to the number of lines in tColumnNames
    put line i of tColumnNames into tColumnName
    set the dgColumnTooltip[tColumnName]    of grp 
"rwMatrixObj_DataGrid" to tColumnName
    set the dgColumnWidth[tColumnName]  of grp 
"rwMatrixObj_DataGrid" to 75
    set the dgColumnAlignment[tColumnName]  of grp 
"rwMatrixObj_DataGrid" to "right"
    set the dgColumnSortType[tColumnName]   of grp 
"rwMatrixObj_DataGrid" to "numeric"
    set the dgColumnSortDirection[tColumnName] of grp 
"rwMatrixObj_DataGrid" to "descending"
    set the dgColumnIsEditable[tColumnName] of grp 
"rwMatrixObj_DataGrid" to false

  end repeat

The first time this executes it takes just under 3 minutes for this size 
of data (254 columns). However, the second and each successive time in 
the same session it takes just under 30 minutes!


Any idea why it would take so long?

Thoughts on how to speed it up?

I realize that I could use: 'set the dgProp["column widths"] of grp  
to ' as a single set action vs a loop where 
I am using 'set the dgColumnWidth[tColumnName] of grp  to 
'.


However, there are only Datagid properties so set attributes for ALL 
columns for alignments, visibility, widths, and labels. Therefore, I 
have to use a loop anyway to set the tooltip, sorttype, sortdirection, 
end editability


The column names (in the variable tColumnNames) are file names. Some are 
long (longest is 113 characters) and some contain assorted punctuation. 
I wonder is the column NAMES should be somehting plain ASCII and short 
and the column LABELS contain the file names?


This is all in LiveCode 9.5.1 on Windows. Timing is approximately the 
same in a Standalone or the IDE.


Anyway, if anyone has a good idea of what is taking this 30 minutes, 
ideas would be very welcome!

This I did not know. Thank you.


Instead of having them in the loop, prepare the column size, columns label,
etc and uses the table properties existing for setting all the values at
once. In this case the refresh of the datagrid is internally made only one
time.


This I did know. As I said in my initial message:

SO, while I can change the code to set the column ALIGNMENTS and WIDTHS 
all at once, I am still stuck setting the TOOLTIP, SORTTYPE, 
SORTDIRECTION, and EDITABILITY column by column in a repeat loop. So 
what do I do about setting the TOOLTIPs? There is NO 'set the 
dgProp["column tooltips"] of grp  to '


Obviously, I can just TRY using LOCK MESSAGES (as Paul Hibbert 
suggested), but I am concerned that may cause more problems that it 
solves. Does anyone KNOW for sure?

Slightly off topic, but I have run into time where I wish I could lock a 
specific message or set of messages. Something like:


Lock messages for "mouseUp,mouseDown"

Generally, like so many many things in LiveCode, you can code this with 
a flag in the handlers or a bunch of alternatives. However, I still find 
myself running into this now and then.

Reduced to a consistent 1.5 to 2 minutes by revising the setting of 
datagrid column properties


the columns themselves, widths, and alignments set all at one. Tooltips, 
sort type and sort direction set in a loop in revised code.


I still do not understand why in the original code, when 1st set in a 
session it took 3 min and on subsequent updates in the same session, it 
took 30 minutes. The datagrid must be slow erasing certain properties 
for updating.


Thank you to everyone who responded with advice.

Drawing a blank on simple code...

[Paul Dupuis via use-livecode]

I have a set of custom properties in stack "X", a lot of which begin 
with "options_"


I want to loop through them and get the values, so I have:

  local tDisplayList
  put the customKeys of stack "X" into tProperties
  filter lines of tProperties with "options_*"
  if tProperties is empty then exit to top

  repeat for each line tLine in tProperties
    put the customKeys[tLine] of stack "X" into tProp

    -- do stuff here
  end repeat


When I walk through this code in the debugger, I see that tProperties 
gets a list of the names of all custom properties in the "X" stack. YEA!


Then I see that that list correctly gets filtered to just those that 
begin with "options_" YEA!


Then I see the in the repeat loop the variable "tLine" get the name of 
each "options" property in succession. YEA!


PROBLEM: put the customKeys[tLine] of stack "X" into tProp DOES NOT 
fetch the value of the indicated property into tProp


I know this is simple - and I have coded it before - but I can seem to 
find my past code in prior projects and obviously am missing something.

So I assume these are members of a customPropertySet, whose name I'll

Actually, the custom properties were NOT part of a customPropertySet, 
but were custom properties in the DEFAULT property set AND I apparently 
either never knew or had forgotten that you can not use array notation 
to set custom properties in the default property set since the default 
property set has no name. I could put the  customer properties array in 
an array variable and get the values that way, but to set them I had to 
construct a DO command. They all really should be moved to a custom 
property set (called "options" for example), but I don't have the time 
to change that much code.

I have been periodically looking at assistive technologies for LiveCode

Certain OS bases assistive tool like screen magnifiers do work as they 
are application independent. Unfortunately, screen readers and voice

most LC app don't use through out.


With LC 9 and the FFI/Widgets it may be possible to build integration

application specific integration, but I don't think anyone has done it.


For mobile ADA compliance, you best bet is to test your app with 
whatever OS level assistive tools are provided with iOS and Android or 
look in the associated App store for application independent assistive 
app to test with your app.


If you mobile uses all native controls it *may* work better with OS or 
3rd party assistive tool, but that is a guess. I have no mobile app 
experience.

Unicode and languages

[Paul Dupuis via use-livecode]

In all the added stuff the LC7 and higher Unicode engine includes, is 
there any way to determine the LANGUAGE of a range of text?


USE-CASE

We have a tool that helps researchers transcribe text from digital 
media. It is used internationally. We have added spell checking using 
lclSpell form Live Code Labs, a LiveCode store add-on.


For lclSpell, we only have Dictionaries for a small set of languages. 
You can build you own Dictionaries for lclSpell, but we'll still only 
have Dictionaries for a small subset of the languages people transcribe 
in. We also have people who do BOTH transcription AND translations.


For example, transcribing a Chinese language media recording, typing in 
the Simplified or Traditional Chinese characters AND then translate it 
to English, typing the English translation after the transcription.


With lclSpell (or I suspect ANY LiveCode compatible spell checker) if 
you try to spell check a reasonably large chunk of text that is NOT in 
the same language as your Dictionary, it ties up LiveCode forever, or at 
least such a long time and most people would force-quit. It is after all 
marking every word as misspelled and trying to do whatever it does to 
determine  that.


Now, you can react, that the researcher should just KNOW better than to 
do Spell check a text in a language that is not their loaded Dictionary! 
However, people are people, and will do such things and expect software 
to protect them from their own mistakes. Also, with mixed transcription 
and translation, you do want to spell check the English part and skip 
the Chinese (if you do not have a Chinese Dictionary)


So, we're looking for a way to detect the LANGUAGE of a range of text, 
in a LiveCode field, to be able to then determine whether it matches the 
current (or any available) dictionary or not and act accordingly.


There is a "fontLanguage" function in LC, but that seem to predate 
Unicode Everywhere and seem pretty useless now.


For example. in a new stack, with a single scrolling field, we paste in 
a Chinese text and then execute:


put the fontLanguage of (the effective textfont of char 1 to -1 of fld 1)

and get "ansi". Even you you set the range (char 2 to 3) that is 
specifically Chinese (no white space), it still returns "ansi". The 
textFont returns empty and the effective textFont returns "Segue UI"


I don't even know if language exists in the IBM Unicode engine as some 
exportable property a future version of LiveCode could expose.


Any clever ideas or thoughts on this problem are welcome.

Unicode doesn't deal in languages but 'scripts' e.g. English and 
French are both written in the Latin script, whereas Ukrainian can be 
written in either the Latin or Cyrillic script.


LiveCode gives you access to the unicode properties of all codepoints 
(as held by ICU) via the 'codepointProperty(codepoint, property)' 
function.


e.g. codepointProperty("A", "Script") => "Latin"
 codepointProperty(numToCodepoint(0x03B1), "Script") => "Greek"

This might at least help to cut out trying to spellcheck things which 
are definitely not the languages you do have dictionaries for.


Warmest Regards,

Mark.



Thank you Mark!

That is a least a start as to minimizing the problem for our customers. 
We can make a table of Scripts to Dictionaries and at least prevent 
erroneous spell checking of Chinese with an English Dictionary!

Possible Catalina problem...

[Paul Dupuis via use-livecode]

We have run into a possible problem. Researchware makes two 
applications, HyperRESEARCH and HyperTRANSCRIBE. We have new forthcoming 
versions of both built on LiveCode 9.5.1.


These two applications are code signed and the DMG is code signed, 
notarized, and stapled for Catalina. They both work fine on testing on 
macOS ranging from Mavericks (10.9) to Mojave (10.14).


We also only have a single Catalina system to test on. On that single 
system, each application seems to work fine, but if we run them at the 
same time, the second app to launch throws a script error on startup - 
and it looks like it may be related to network actions on startup.


We have a TON more testing to do, but I wanted to ask if anyone have 
seen ANY Catalina specific problems running multiple LiveCode 
standalones at the same time?


Our hope is that this is a problem SPECIFIC to our single Catalina mac 
and not a LC Engine or tsNet Catalina specific bug of some sort. To know 
that some one else has run multiple LC 9 standalones at the same time on 
Catalina and seen no errors would be kind of encouraging right now.

Hi Paul,

I have started three LiveCode standalones on Catalina with no problems. But

If you like, I can test your apps on my MacBook with Catalina in order to check 
if the problems are replicable.

Catalina Entitlements or Permissions (was Possible Catalina problem)

[Paul Dupuis via use-livecode]

We're having some macOS Catalina permissions/entitlements issues

We have applications that we deliver for Catalina where the application 
(LiveCode standalone) is code-signed. It is then packaged in an 
installers (LiveCode standalone) and the installer is code signed. That 
is then placed in a DMG, which is code-signed, notarized, and stapled.


This has worked for us since October when Catalina was released.

It still works, except sometimes, after successful downloading and 
installation, when the applications is first launched, Catalina does not 
ask for the permissions the Application needs. Instead certain handler 
throw an execution error. The handlers that produce the errors on 
startup when Catalina fails to ask for permissions have the following in 
common:


The set the defaultFolder to folders such as:

/Library/PreferencePanes
/Users//Library/Preferences -- this is using the code: the 
home folder & "/Library/PreferencePanes/"

or
/private/var/folders/fj/0llnt4vs44vfzy4r97k_wngcgp/T/TemporaryItems 
-- this is 'the temporary folder' on Mojave or Catalina. On Mavericks 
and earlier teh temporaty folder was 
/Users//Library/Caches/TemporaryItems


After setting the defaultFolder, the code gets 'the files' or 'the 
folders' and fails (actually we've not pinned down whether it fails on 
set the defaultFolder OR on the call to 'the files/folders')


Going to Apple (menu) > System Preferences (menu item) > Security & 
Privacy (control) > Privacy (tab) and selecting Full Disk Access and 
adding our applications prevents these errors from occuring.


The issue is clearly with Catalina failing to detect and ask for the 
correct permissions. This is a known issue a number of developers have 
run into. See https://forums.developer.apple.com/thread/125438 as one 
example where an Apple support person admits that detecting what 
permissions a process is requesting that is tied back to your user 
visible app (something Apple calls 'responsibility tracking') is really 
hard.


For iOS and Android, you can specify entitlements or requested 
permissions in the Standalone Builder Settings. How do you do this for 
macOS Catalina?


Does anyone know if there is a way to specify entitlements for a macOS 
desktop app built in LiveCode? I have been googling and googling and can 
seem to find anything. I found one discussion on stackExchange that seem 
to imply that the PLIST file could be edited to specify entitlements. I 
have tried the Apple Developer site, but SO MUCH of it is orient towards 
people with lots of Apple Developer experience and focuses of C and 
SWIFT and Apple specific technologies I don't understand.


I can edit the XML in a PLIST file in the standalone bundle IF I only 
knew what to add?

Re: Catalina Entitlements or Permissions (was Possible Catalina problem)

[Paul Dupuis via use-livecode]

Hi Panos,

Thank you very much. The discussion in the bug entry answered  lot of my 
questions. I have one last thing I hope you or someone can point me two, 
which is a list of Apple macOS "entitlements"


From the bug entry I see:

com.apple.security.device.audio-input

com.apple.security.device.camera


I need to figure out the ones for email access, finder integration 
(drag/drop), internet access, and disk access.


We've seen Catalina ask the user for:

1. HyperRESEARCH requests access to the Internet (if Apple Firewall is
   turned on). - We assume this is because out app needs to check for
   new versions and updates and for license management.
2. HyperRESEARCH requests access to the "Finder". - We assume this is
   to receive AppleEvents (system messages) if a Study file is double
   clicked or dragged and dropped on HyperRESEARCH to open the Study.
3. HyperRESEARCH requests access to your "Contacts". We assume this is
   for access to send an email for an error report if an error occurs.
   Our App does not accessing any names or addresses.

I have tried Google for macOS or Catalina and entitlements but all I 
seem to be able to find is articles from the user's perspective, not 
developers information.

Re: Catalina Entitlements or Permissions (was Possible Catalina problem)

[Paul Dupuis via use-livecode]

Arghh!

So I am Googling and Googling and hunting around the Apple Developer 
site to try to find a comprehensive list of macOS entitlements so I can 
code sign my app with the the entitlements my app needs to not generate 
errors under Catalina.


I want to execute: codesign --verbose --deep --force --sign 
"" --entitlements 
 
with an entitlements.plist file with entitlemenst to grant my app 
certain disk access, internet access, email access, and finder integration.


Finally, I find this article that basically says Apple has no 
comprehensive list - their published developer documentation has not 
kept up with the additions they have been making in point release 
updates to macOS: 
https://eclecticlight.co/2019/02/26/entitlements-how-apps-get-back-what-theyve-given-up/


The lack of an up-to-date comprehensive entitlements list was apparently 
bad enough that a guy by the name of Jonathan Levin built a database to 
keep track of them since Apple couldn't (or wouldn't), so at least there 
is this hand database at http://newosxbook.com/ent.jl


Now, if only I could figure out from the database which ones I need to add.

Perhaps, it is time to switch to Mark Talluto's suggestion to use 
AppWrapper!

Re: Platform Divergence

[Paul Dupuis via use-livecode]

We make and sell a desktop application (Windows and macOS) for a niche 
research market. I expect when Apple does their migration to a common 
processor and OS, Apple Developer's will have to go through all of Apple 
hoops for all their platforms.Most of our customer don't care about UI 
widget animations. They want the app to do certain functions and do them 
well and quickly to work with their data. As long as the UI is 
effective, whether it conforms precisely to Microsoft or Apple UI 
guidelines is secondary. So, even if you only care about desktops, your 
app will have to be sold through Apple's single App Store, conform to 
all screen sizes on all their devices, and follow all their UI 
guidelines, etc.


At that point, given that Windows is 2/3rd of our market and macOS 
1/3rd, we'll drop support for macOS sadly. I say sadly because our 
application originated way back in the late 1980 as a HyperCard App for 
MacOS.


But, to your point, your concern IS valid for those people wanting Apps 
from you that they insist MUST conform to all of Apple's esoteric 
requirements. It is likely it will become increasingly harder for the 
LiveCode ideal of develop once and deploy everywhere.

This year’s WWDC shows Apple is moving to a unified ‘system' for all their 
products: Mac, iPhone, iPad, Apple Watch, AppleTV.
The Apple development environment promises to produce a single app capable of 
running on all, or almost all, of Apple devices. This unification promises to 
be quite convenient for Apple developers.

In contrast, over the last decade or so there has been an ever increasing 
divergence in UX between major operating systems: Apple, Windows, Linux, 
Android. The days when systems were so similar that you could rely on the 
commonality of a handful of UI elements across platforms seems over to me. 
That’s troubling because such commonality is fundamental to LiveCode’s approach 
- write once, run everywhere.

In watching WWDC sessions it’s pretty clear that even simple UI elements have 
become more like UX elements having intrinsic and complex properties, such as 
certain visual and behavioral animations. Users readily learn to expect these 
behaviors. Yet such things are increasing difficult to fake with LiveCode’s 
basic palette of objects.

Enter LiveCode Builder and LC Widgets. They offer the promise of 
platform-specific UI elements - a promise fulfilled with some simple elements 
like iOS Native Button or Android Native Field. But I’m concerned that as 
platforms diverge in the interface experiences they present to users, that LC 
and LC developers will have difficulty satisfying users' divergent expectations.

Is my concern valid?

Mora Catalina permissions woes....

[Paul Dupuis via use-livecode]

List Folks: A head up of a Catalina issue:

If your code signed Standalone is trying to access stacks that are 
OUTSIDE the app bundle under Catalina, sometimes Catalina will not 
properly detect your apps need for access. You will not get an "App 
wants access to blah blah: Allow or Deny" dialogs and you app will throw 
a script error (if you have assumed successful access and not coded for 
errors)


In our case, we have the App (bundle) and a folder of stacks that sits 
next to it, both in a containing folder that is what is installed where 
the user installs it. So


FOLDER: OurAppFolder
> OurApp.app
>FOLDER: OurStacks
>> Some library stacks

We construct a full path to each library stack in "OurStacks" in a 
variable called tLibrary and when we execute

if there is a file tLibrary then
  start using tLibrary
end if
for the 1st library, we get a script error on the start using statement. 
The test for existence does return true.


start: can't find object

If you go to Apple (menu) > System Preferences (menu item) > Security & 
Privacy (panel) > Privacy (tab) > Full Disk Access and grant 
"OurApp.app" access, then subsequent launches work flawlessly.


This is clearly a Catalina entitlements/permissions issue.

We have distilled a test stack and have seen the error occur multiple 
times. The problem is we have not found a recipe that reproduces the 
error 100% reliably.


I have seen discussions that suggest Apple has provided NO entitlement 
you can code sign your app with to allow full disk access. They see 
individual folder access (like Documents, Desktop, etc.) and Full Disk 
Access (which subsumes all individual folder access) as being only 
grantable by the user.


QUESTIONS:

1) Any one else run into any situations where Catalina is failing to 
detect and ask for ANY given entitlement?


2) Any one else run into failures in detecting and asking for disk 
access entitlements?


3) If you have this problem, do you you tell customers to grant the app 
full disk access before running it? If so, how do you phrase that in a 
way that makes them comfortable and works?


4) Does anyone know of an entitlement for macOS Catalina that allows 
full disk access? Or even access to say the Applications folder?



P.S. If we can produce a recipe that is reliable, we will file a bug 
report on this. At the very least, LC may want to update "start using" 
to return an error code so you don't have to trap it with a try...end 
try block.

I asked a similar question back on June 5th under the subject "Unicode

(essentially the fontLanguages function no longer applies)


--
Unicode doesn't deal in languages but 'scripts' e.g. English and French 
are both written in the Latin script, whereas Ukrainian can be written 
in either the Latin or Cyrillic script.


LiveCode gives you access to the unicode properties of all codepoints 
(as held by ICU) via the 'codepointProperty(codepoint, property)' function.


e.g. codepointProperty("A", "Script") => "Latin"
 codepointProperty(numToCodepoint(0x03B1), "Script") => "Greek"

This might at least help to cut out trying to spellcheck things which 
are definitely not the languages you do have dictionaries for.

In general, I am more of a Windows person than a macOS person, but one

More Standalone Building Weirdness...

[Paul Dupuis via use-livecode]

I have a stack that when I build into a Windows Standalone (only 
Windows) in LC 9.6.0 under Windows, the dialog that says "Attaching 
Engine..." never finishes.


The Standalone gets built and runs properly, but the "Attaching 
engine..." dialog in the building process never finishes (waiting over 
an hour for a tiny stack) and I have to bring up teh Task Manager and 
force the LiveCode app to exit.


Anyone seen anything like this? Have any idea what causes it?

Since the app does get built and runs fine, and I am under a deadline, I 
don't really have time to troubleshoot it. It is easier to just force LC 
to exit, but if someone has seen this and knows the cause, please let me 
know.


Thanks in advance.

Re: More Standalone Building Weirdness...

[Paul Dupuis via use-livecode]

The stack where building a Windows Standalone just stays on "Attaching 
Engine..." forever had no 'closeStack' handlers at all.


I added the following:

on closeStack
   -build close issue--
   if the environment is "development" and \
 there is a stack "revStandaloneProgress" and \
 the mode of stack "revStandaloneProgress" > 0 then
  exit closeStack
   end if
   ---
   pass closeStack
end closeStack

An there was no change in behavior. Under LC960 (I have not tried other 
versions), it builds the standalone, but then just remains on "Attaching 
engine..." and I have to force LC to exit.


If no one else has seen anything like this, then it is probably 
something about the stack. I don't have problems building other 
standalones in LC960.

It was in one of the release notes.

Maybe that is holding your build to complete



on shutdownRequest
answer question "Are you sure you want to stop?" with "Y" or "N"
if it is "Y" then
   pass shutdownRequest
end if
end shutdownRequest

on closeStack
-build close issue--
if the environment is "development" and \
  there is a stack "revStandaloneProgress" and \
  the mode of stack "revStandaloneProgress" > 0 then
   exit closeStack
end if
---
lock messages
quit --triggers shutdownrequestmessage, if not handled then it hangs
pass closeStack
end closeStack

Old stack will not save or save as...

[Paul Dupuis via use-livecode]

I have a really old stack (the file ends in .mc for Metacard)

When I open it in LiveCode, the save and save as are disabled in the 
File menu. This us under Windows and the same in LC 4.6.4, LC 6.7.11 and 
in LC 9.6.0, the Save and Save As are enabled, but when I select the 
stack and try to Save As... it thinks it is saving "revRefactor" not my 
stack.


My stack opens and I can see and edit UI objects, properties and 
scripts. I just don't seem to be able to save it.


Just changing the extension to .rev or .livecode makes the stack 
unreadable in LC464, but it will still open in LC960, but still can save 
or save as (File menu items greyed out)


Anyone seen this? Know what to do?

Good guess, but no winner. However, your suggestion did put me on to the 
answer.


The stack was set to "modeless". If I execute in the message box

save stack "XYZ" as "C:/Users/MyUser/Desktop/XYZ.livecode" -- no lock. 
No error, but no save.


However, after I execute in the message box:

topLevel "XYZ" -- everything now works. The File save and save as menus 
items as enable and behave correctly.


Why I can't save or save as a modeless stack in IDE is a mystery to me.

It is also a mystery to me how Bob suggesting "suppress messages" led my 
brain to look at a stacks Modality, but it did, so thank you Bob!

Re: Playing movies in LC_ Docs??

[Paul Dupuis via use-livecode]

Yes, there is a lot of information that circulates on the forums or 
lists or in people's head that probably should be in the LC documentation


In the LC9.x.x series, the Player supports any audio or video formats 
supported by Apple Video Foundation (AVF) on macOS - google the apple 
developer docs for AVF formats supported by macOS version. The Player 
supports any audio of video formats supported by DirectShow on Windows. 
Google DirectShow formats supported to find those.


NOTE while there is over lap, there are also formats supported only on 
one platform or the other.


Also, unfortunately, if you are planning on doing anything more complex 
that placing a video in a player and letting the user play it, you 
should search the LiveCode quality center for player bugs - there are 
many dozens. Some minor, some more serious.

formattedRect, formattedLeft, formattedWidth of chunks

[Paul Dupuis via use-livecode]

Just a heads up to anyone else out there who may be having VERY hard to 
track down crashes in LC 9.x.x.


The following functions: formattedRect, formattedLeft, formattedWidth 
when operating on chunk expressions (i.e. char X to Y of field Z) can 
cause an engine crash for certain field content.


This is present in all versions of LC 9.x.x (actual back to some version 
of LC8)


The issue is when the chuck contains tab characters.

See https://quality.livecode.com/show_bug.cgi?id=22882

FYI: formattedTop and formattedHeight of chunks still work.

Re: formattedRect, formattedLeft, formattedWidth of chunks

[Paul Dupuis via use-livecode]

If you control the content, it is probably not an issue. In our case, 
the content and the ranges (char x to y) are set by the people that use 
our product - we have no control - so we end up with customer's trying 
to do their research and suddenly our product hard crashes, sometimes 
resulting in lost work. They don't understand why since bunches of other 
documents they are working with all process fine. Even the document that 
is causing the crash may seem fine UNTIL they add a bookmarked range 
that includes the tabs. As tabs are invisible in MS-Word and a lot of 
MS-Word user are not really skilled at formatting, they may end up with 
tabs in their documents that they are not even aware they are there.


This one really was a pain to track down as we had to get a customer, 
with the crashing, who was willing to provide their whole research study 
so we could reproducethe error in-house and then tracing it down in the 
IDE took a very long time to go through the 1000's of lines of code to 
find the crash on the 'formattedRect' call.

Re: text manipulation with Chinese characters (unicode): guide?

[Paul Dupuis via use-livecode]

As mentions, Unicode in a field just works (there is a known issue with 
Thai word breaks and another with printing Hindi)


If you want to get Chinese (traditional or simplified) into a field, you 
can:


1)  get the text from a Utf8 ot utf16 text file and textDecode it i.e 
put url ("file:"&filepath) into tContent; put 
textDecode(tContent,"utf8") into fld "someField"
2) get the text from an RTF file, like the above, but set the rtfText of 
the field to the imported rtf data
3) use a 3rd party library, like Wordlib (see the livecode store) to 
read Microsoft Word .docx or Open Office .odt files

We are now translating some stacks to other languages which require

Is there a good way to do that without using a lookup table or 
metadata? The file names doesn't need to make sense syntactically. For 
example,


   l’Académie française -> lAcademiefrancaise.livecode

...or similar, whatever works. The user will never see the file name.



You should probably use the same model as LiveCOde uses to match files 
names returned from the files("detailed-utf8") function:


urlEncode(textEncode(normalizeText(,"NFC"),"utf8"))

Converts:
Russian-русский-Lipsum.docx

To:
Russian-%D1%80%D1%83%D1%81%D1%81%D0%BA%D0%B8%D0%B9-Lipsum.docx

For what your doing, I think that using:

urlEncode(textEncode(,"utf8")) -> gets 

and

textDecode(urlDecode(),"utf8") -> gets 

should be enough.

Accessing files on a local network file server - BEST PRACTICE?

[Paul Dupuis via use-livecode]

This question may have an obvious answer, but I am brain dead today, so 
here goes:


I have a app installed with some customers in a Windows network 
environment. They have all their laptops set so that their Home 
directories are on a local network server.


So, where as on a local laptop, specialFolderPath("documents") might 
return "C:/Users//Documents" as the path, for them 
specialFolderPath("documents") returns something like 
"//s1.somedomain.com/mountPoint//Documents"


We save a number of folders and files in the user's Documents folder. In 
some cases, if the file is not present (i.e. if there is a file tFile is 
false) we regenerate the file from a default.


Sometime, the server is offline or the user is disconnected from the 
network.


What is a good way to differentiate between:

1) one of these files is not present so must be regenerated, i.e

if there is not a file (specialFolderPath("documents")&slash&tFilename) then
  -- regenerate the file tFile at location specialFolderPath("documents")

Versus

2) The Server (//s1.somedomain.com/ is disconnected to down?

So that in case (1) , we regenerate the file and in case (2) we present 
a warning that the server is disconnected or down?


Mu gut says this should be simple, but I just can not wrap my brain 
around it today.

I know very little about Windows network addresses, but from the 
example you gave, I'd check to see if (slash-delimited) item 1 of the

Thanks for thought.

In a Windows server environment (i.e many corporation, government 
agencies, etc.), computer are often set so tat their specific "User" 
directories (Documents, Desktop, "Home", etc.) at on a server rather 
than local disk. So a path to a file called "somefile.txt" is a user's 
Documents folder looks like:


//s1.somedomain.com/mountPoint//Documents/somefile.txt

The question is, if you execute the line of  LiveCode script:

if there is a file 
"//s1.somedomain.com/mountPoint//Documents/somefile.txt" then

  -- true
else
  -- false
end if

In the "true" case, the file is there, which means the server and 
network are both accessible. Yea! proceed with whatever.


In the "false" case, you do not know whether the FILE is missing OR the 
NETWORK is disconnected or the SERVER is down.


It is in the "false" case that I am looking for approaches (if there are 
any) to tell the difference between

1) the file is missing
and
2) the network or server is down.

Bernard has a suggestion of keeping an invisible file. Being hidden, it 
is unlike that it could be removed by intent or accident and so, if the 
file I am looking for "somefile.txt" does not exists, I could test for 
the hidden file. If that exists, I know my file is missing and the 
server and network are still up. If the hidden file also does not 
exists, the server or network is "probably" down.


I could probably improve on Bernard's suggestion by testing for:

if there is a folder "//s1.somedomain.com/mountPoint/" then
  -- the server is up
else
  -- the server or network is down OR or the user has been fired and 
their account delete!

end if

I was hoping someone out there had actually dealt with LiveCode working 
with files on a Windows network server and have a definite approach. 
Maybe testing for the user's folder is the definitive way OR the 
mountPoint folder may be even better?

Re: Accessing files on a local network file server - BEST PRACTICE?

[Paul Dupuis via use-livecode]

Thanks Bob,

Yes, the error messages you get on a failed file open are pretty generic.

I am thinking that whether Mac or Win, the key is to check for whether 
there is a folder:


/volumes/mountpoint/ (osx)
or
//server/mountpoint/ (win)

For a given path tPath, I can tell if it is a windows server bu looking 
at the 1st two characters of tPath and if they are // then I can try t 
pull off //server/mountpoint and test for a folder by that name exists.


However, on OSX,

/volumes/mountpoint/ looks just like any local path.

I can see how it would be helpful if the result contained “path not

Re: Problem an Repeat Loop

something like this? It might be easier to help if you explained what 
you are trying to do. Have all the cards in this stack been created 
already? i.e. do you have sTotalSceneCount cards? Does each card contain 
a field called "mainText" and an image called "slideImage"?


set the itemDelimiter to “|”
repeat with x = 2 to sTotalSceneCount

Re: Canvas Limited to 32767

[Paul Dupuis via use-livecode]

You would think with 32K px at 72px/inch being like 450 inches that the 
32K limit would not be an issue, but I have run into it as well


I have written a custom graph (like a bar graph for example sake) that 
is generally fine with most customer data. However, on one customer data 
set it started blowing up. It turns out that one of the bars was "huge" 
(an the order of 400k px) at the zoom level where they could see the 
details in the remaining bars. So, in this case the researchers wanted 
to "zoom" in on noise in a larger data set, causing that larger data to 
become huge in a graph.


And yes, you can code in bounds limits and attaching labels to indicate 
a bar is out of bound or exceeds display area, etc., but I do agree that 
for a number of applications having a large drawing area would be a big 
improvement.

Is this for the weird recommended mobile workaround of putting a text field

Re: formattedwidth/height does not work with some fonts

[Paul Dupuis via use-livecode]

It is different symptoms from this bug 
(https://quality.livecode.com/show_bug.cgi?id=22882) but it could be 
related in the code?


I recommend filing a bug report and I will be happy to add a note 
connecting the two bugs. The more issues found surrounding "the 
formattedWhatever" functions, the more likely we may see action at 
fixing them sooner rather than later.

Re: Bug: jumping stack windows (when supress messages is off)

Window 10 has a snap to feature on by default that will try to snap any

moves close to a screen edge. I have not explored the feature fully, so 
I am not sure of the details.

Open 2 windows in TextEdit. Move one close to the other and they will snap into

will snap into place.

Same goes for Safari with two windows open. And the same happens in the IDE.
If that is what you describe on a single monitor setup then it is an operating

Slightly OT: Windows Code Signing

[Paul Dupuis via use-livecode]

My Windows Code signing cert for signing LiveCode standalones has expired.

I purchased it from instantsll.com (3 year) which has become sectigo.com 
and it appears that they never moved over old accounts since my prior 
username, email, and password do not work nor does the email work for 
password recovery.


So I bought a new one from comodosslstore.com (which turns out is also 
sectigo.com). Verification was quick and automate - no problem.


Now my cert is ready, but the download/install instructions requires 
Internet Explorer 11 or Firefox 68 or older (Firefox is at version 82 
and Microsoft Edge is what comes with Windows 10 not Internet Explorer 11


Their support documentation is conflicting and terrible (IMHO).

It is not too late to cancel the order and buy elsewhere. Does anyone 
have a recommendation for a supplier of Windows Code Signing certs that 
have a simple and straight forward process for buying AND getting the 
.p12 file you ultimately need for code signing?


This is kind of urgent since we are unable to sign until we get a new cert.

Re: Slightly OT: Windows Code Signing

[Paul Dupuis via use-livecode]

Thank you Matthias,

I did notice the unexpectedly large price on Sectigo direct and purchase 
a 3 year through comodosslstore.com for about $212.50 USD, so at an okay 
price for me. Mine is just a plain signing cert, not the EV.


What I ran into that was very frustrating was the browser requirements. 
You would think - especially with the vagueness of browsers supporting 
certain features - that they would make an app to do their own CSR 
generation at the start of the process and the same app can do the 
download at the end


I do not have any older version of IE (on VMs or otherwise). I did 
download Firefox 68 (current release is 82!, but 68 is only from early 
2019) but could not get it to work. Finally I was able to download my 
cert via Safari under Mojave and move it to my Windows 10 via Dropbox 
and under Windows 10 use the MMC (Microsoft Management Console) to 
import it and export it in p12 (.pfk) format for use in signing 
Standalones. Success, but what a pain to go through.


If anyone has found a Issuer that will just let you download the code 
signing cert as a .p12 pr .pfk file, I'd like to know.

Hi Paul,

first of all buying directly through Sectigo is expensive. If you purchase from

I've  purchased in July a 3year code signing certificate ( not the ELV) for 207 
Euro for all 3 years. The certifcate was also delivered by Sectigo. And i was 
able to download the certificate on my Windows 10 VM with Internet Explorer, if 
i remember right. I even cannot remember that a special version of Mozilla was 
required.
They only mentioned, that you cannot fetch your certificate with MS Edge, 
Chrome and Safari.
I've did the complete purchase process on my Windows 10 VM.

Re: Windows startup issue

[Paul Dupuis via use-livecode]

The first things is to determine what the error codes mean. I forget off 
teh top of my head, but I things of the first 2 numbers one is a line 
number and the other an error code?


Hopefully someone can chime in who knows for sure. Knowing the errors 
will tell you more about what the likely cause may be.


I suspect it is some sort of permissions issue. In all most all 
instances where we have run into a weird startup issue with just one 
customer, it has turned out to be permissions related. For example, does 
you application create any preferences or license files or temporary 
files? Or try to save anything to disk behind the scenes (i.e. not a 
user driven file save dialog)? If so, chances are the place you are 
trying to write to is read-only.


It could be many other things, but this has been the most common issue 
like this we've run into.

I've been using my own error-reporting for so long I can't recall 
seeing the default standalone handling.


I have made a couple of quickies where I just used LC's error 
reporting, but clumsy as that design is at least the output from the 
"Send Report" button is more useful than the raw list of triplet 
integers.


How has such ungraceful error handling become acceptable?

Why is the least useful thing the easiest for new developers to do?

Shouldn't it be easy for LC devs to deliver a great application 
experience?




One big thing that LC could do to let developer's improve error handling 
and standalone troubleshooting would be to include the 
"scriptExecutionErrors" in Standalones. I know it is along list, but 
would it really add that many more bytes to Standalones relative to the 
current engine size?


I know you can replicate having the error text present by copying the 
scriptExecutionErrors to a custom property in your standalone, but then 
you have to be sure to update it with each engine release. To just have 
it included when you build a standalone would be much better.

I imagine that they could be added to the Inclusions - if on automatic, 
use of the "scriptExecutionErrors" in your code would lead to automatic

Re: Big Sur bugs

[Paul Dupuis via use-livecode]

So Big Sur was released on the 12th. It is not our in user's hands.

Does anyone (or LiveCode corporate) have any update about Big Sur 
compatibility? We have customer's inquiring. We can not afford the time 
to jump through Apple's hoops for any of their beta versions. Now that 
the release is out, we can start testing our apps with it IF we can get 
it installed over one of our Catalina VMs but it would be nice to know 
what testing LC Ltd has done or others have done?

Re: Big Sur bugs

Panos,

Thank you for the rapid-response update!

The link you provide presents me with the error "There is no with the id 
'97748'. " Just knowing a compatible LC release is on its way in 9.6.1 
is a help, but I'd love to see the list of bugs if there is an alternate 
URL to view them.

Hello Paul,

Here are the bugs that have been discovered so far, either by LC users or
by us (LiveCode Ltd):

https://quality.livecode.com/buglist.cgi?regetlastlist=97748

The 2 serious ones have been addressed and are to be tested in our
pre-release build. There are another 2 cosmetic bugs, and one that seems to
affect only the new ARM Macs.

These bugfixes are expected to appear in the upcoming release of LC 9.6.2
RC-1.

Kind regards,

Re: Big Sur bugs

[Paul Dupuis via use-livecode]

No, however, I am running Big Sur in a Virtual Box VM under macOS 
Mojave. All other Big Sur features and functions appear to work fine in 
the VM (we just can not afford Apple hardware for every version of their 
OS from Mavericks to Big Sur. VM's are a lot more versatile as they can 
be clones, snapshotted, and restored when things get messed up)


If I try to just double click on the video under Big Sure, it opens the 
Quicktime Player (?) and I get a "unknown error occurred (-101).


I am glad to hear it is working for you Panos - very glad. Both our 
commercial apps depend on the player object and I was in a panic! I'd 
ask anyone following this thread to please take time to test media under 
Big Sur.


I would be ecstatic to learn in is a VM issue. We'll then move to our 
backup of installing on a partition for a dual (actually more than dual 
as we have about 5 version of macOS each on its own partition) boot system.

Re: Getting a real number from scientific notation

[Paul Dupuis via use-livecode]

So, if you want to concert form scientific notation to a real number, 
you can use the "format" function (see dictionary). Example:


putformat("%1.0f",4.21911E+11) -- outputs 42191100

Is that shat yo are looking for?

Hi friends,

see subject.

I have some values in a CSV with this notation
According to the dictionary I tried:
on mouseUp pMouseButton
   put "4.21911E+11" into tSN
   set itemdel to "+"
   put char 1 to -2 of item 2 of tSN into t1
   put item 2 of tSN into t2
   put t1*10^t2 into tRes
   #x*10^y.
end mouseUp

But tRes is also in scientific notation ->  1e+11
When I set a breakpoint and doubleclick that value
the little popup palette shows a real number however!?

What am I missing and is this the correct way to do what I need?

Thanks a lot in advance!

All this is why I prefer format() over numberFormat. The function is 
more versatile and you get exactly what you specify with less guess work.

LC9.6.2rc build issues?

[Paul Dupuis via use-livecode]

So, I have a large applications. Under 9.6.1 STABLE I open the main 
stack and build the standalone (Windows and macOS) without issue.


I just tried it under 9.6.2rc1 and I get an infinite loop of "duplicate 
stacks" errors and it keeps trying to reload the app over and over?!?!? 
I had to force quit (on Windows 10).


Any one else have any problems?

Re: LC9.6.2rc build issues?

[Paul Dupuis via use-livecode]

okay, this did not happen the next time I tried. The first time I have 
made a number of changes to two substacks in the mainstack (and saved) 
and then tried building the standalone and got the errors and loop.


The second time I made no changes. I just opened the mainstack (and let 
the app startup) and then build the standalones using 962rc1 and it worked.


I have to try making changes again and see if I can get the issue to 
repeat itself.

Now trying to repeat the build issue in LC962rc1, I made an edit to a 
button script. Applied the change, closed the substack window (getting 
prompted to save my changes), and the LC just exited.


Then trying a 3rd time, everything worked as expected.

Maybe it was a bad preferences file that fixed itself or  gremlins!

My client is running Big Sur and says that changing cards in a stack

sometimes the background image. The first few cards are fairly normal, 
but as she pages through the stack it gets slower.


I had her watch Activity Monitor and CPU usage goes up as she 
navigates through cards. At first the display is fairly normal but 
each successive card change increases CPU useage a little bit. She 
stopped when usage got to about 50% when she said it was unusable. 
This was in the IDE. She says the standalone is even slower.


Has anyone seen this? On Mojave and Catalina everything is fine.



I had a weird display issue where a transition between two cards left 
with one card semi-transparent behind the new card. It was also slow. I 
have a visual effect dissolve between these two cards I removed the 
visual effect and changing between the cards was fast and clean.


Examine any visual effect transitions you may have between cards.

You can search the Livecode Quality center for Big Sur bugs. As I recall 
the 3 main ones were:


1) A bug with custom window shapes (not an issue if you do not use any 
custom window shapes)
2) A bug with the highlights on tabbed buttons (not an issue if you do 
not use tabbed buttons - also there was a script work-around available)

3) An issue with dialogs displayed "as sheet"

These bugs are resent under Big Sur (regardless of whether you are on 
the M1 chip or Intel) in LC 9.6.1 and are fixed in 9.6.2rc1


Again, search the https://quality.livecode.com/ for "big sur" for details

Re: Building a Standalone MacOS App in 9.6.1

[Paul Dupuis via use-livecode]

macOS Catalina or Big Sur apps have to be code signed AND notarized. You 
must have the command line tools installed and there is a non-trivial 
number of commands you have to execute to prepare you app for code 
signing, then code sign it, and then notarize it, including obtaining an 
app specific password from Apple.


Livecode has a pretty decent tutorial on their web site on the whole 
lengthy process.

Catalina

Many errors. Perhaps someone could shed some light.

This error is the first. "replacing existing signature xcrun: error active 
developer path”

I did see a comment on the LC Forum that suggested

sudo xcode-select —install, to install the command line tools.

I carried this out, still no luck.

Installed 9.6.1 RC1. Still no luck.

Is it necessary to have Xcode installed for this to work?


Thanks

Terry

I can happily build a MacOS app without code signing or notarizing the app from 
Big Sur and Catilina. I guess this is needed for an iOS app, but then again you 
cannot build an iOS app with LiveCode Community




Sorry, I thought you meant building a macOS app to deploy to other 
people rather than for your own use on your own computer. Gatekeeper 
will throw a ton of obstacles and warnings for any app not signed and 
notarized that you download and try to install on Catalina or Big Sur. 
Technically, there is probably some way to instruct people how to 
circumvent Gatekeeper objections.

Re: LC & Mac M1 Chip

[Paul Dupuis via use-livecode]

I know the mothership does not like to estimate release dates, but does 
anyone have a sense of when LC 9.6.2 STABLE may be out? And more 
importantly, whether it will come with 'official' support for the M1 
hardware or at least a fix for this apparent M1 specific bug: 
https://quality.livecode.com/show_bug.cgi?id=23013


We're getting a certain amount of pressure for our primary app to 
support the Big Sur and the new hardware. LC9.6.2rc1 address our main 
Big Sur issues (not that there were many), but the dashes in menus on M1 
(#23013) concerns me as we have several customer who have said they are 
upgrading to M1 laptops.

Re: LC & Mac M1 Chip

[Paul Dupuis via use-livecode]

Andre and Panos,

Thank you both. That given us some confidence we can release under LC 
9.6.2rc1 so that customers can go ahead with their M! Big Sur systems as 
they want to.

Hi Panos,

Just updated https://quality.livecode.com/show_bug.cgi?id=22955 with a

I can't reproduce the bug, I guess it is fixed.

Hello all,

Just a clarification - the bug about dashes in menus in standalones on Big
Sur is:

https://quality.livecode.com/show_bug.cgi?id=23009

and not https://quality.livecode.com/show_bug.cgi?id=23013

BTW, could someone that has a M1 Mac confirm that in the LC 9.6.2 RC-1 IDE
there are no dashes in front of the menus - in other words that this bug is
fixed:
https://quality.livecode.com/show_bug.cgi?id=22955

Thank you!

Kind regards,

Yes; important to support! I'm looking in that direction too. It'll be
popular, plus it's what I can afford. Many people in the same boat.

(Backstory: Apple's biz model forces Apple to force us to spend on
hardware. The mobile herd sticks with Apple, so the dev herd does too,
so wallets must open and notes must rain down. But not satisfied yet
with the rain from software tweaks, so now hardware tweaks too.)

I'm planning to get an M1 Mac this year, to get back on the bleeding
edge for a while. It's time. My old Mac hardware is still perfectly
good, it was well-built and has zero issues, but finally has been pushed
into what will soon be an untenable corner by the combo of new OS to
support and new chip to support. But the older Mac will continue to
serve for testing and for transition dev if needed.

  > a sense of when LC 9.6.2 STABLE may be out?

Could be roughly predicted, maybe, by looking at what they are working
on. I actually agree with LC's anti release date policy; announcing firm
dates is just begging for another issue to pop up. But since Apple's biz
model places so much pressure on devs to keep up, a sense would be good.
Especially since third-party addons and widgets also have to keep up
with our ecosystem.

(Another backstory: Don't forget the stable/stable linguistic play; I've
seen RCs here that were actually more "stable" than the final, because
glitches, regressions, and extra bugs are sometimes - perhaps often -
introduced in the very process of fixing bugs. Depending on a stable to
be stable is a gamble, and depending on the specific features in an app,
there are times when the RC is more reliable. Nevertheless I really hate
to publish anything with an RC; only when forced to do so.)

BTW, Paul knows all of this very well. I'm just replying publicly in
case the backstories will benefit other readers here in the process. :)

Best wishes,

Curry Kenworthy

Re: lock screen

[Paul Dupuis via use-livecode]

When I have a handler that needs to lock the screen I will often do the 
following


begins handler

put the lockScreen into tPreserveLockScreen
if not tPreserveLockScreen then lock screen
...
code
...
if not tPreserveLockScreen then unlock screen

end handler

Code in our main LC app is large enough that there are instances where 
the some code that calls the handler needs to lock the screen and other 
code that call it does not, but the handler always wants to hide changed 
until done.



On 1/22/2021 9:24 AM, Craig newman via use-livecode wrote:

Something else you might want to to know, though it may only be academic.

LockScreen commands are queued. So if you lock the screen twice, you have to 
explicitly unlock twice in order to clear the locked state.

It does not matter what happens in the flow of code in terms of screen locking, 
whether other command or function calls are made. The queue rules throughout. 
All is reset at idle time.

I’m sure someone else can be more clear, but when the engine gets to an idle 
state then locks should be cleared.  In your example, it would probably clear 
at the end of that mouseUp handler, but aTest would completely run with the 
screen locked.

Is there only one state for the screen, either locked or not locked and when is 
that state changed.

---
on mouseUp

lock screen

aTest

end mouseUp


on aTest

— is the screen still locked here

end aTest



At what point is unlock screen called by livecode without me calling it 
directly.

The docs say when all pending handlers have completed but what exactly is a 
pending handler.

Comments for Properties in the Property Inspector?

[Paul Dupuis via use-livecode]

Random Thought of the Day:

Does anyone else wish that custom properties had an optional comment 
field that could be viewed in the Property Inspector (PI)?


I realize you can always comment properties in the code where you use 
them, but I find myself often in the PI looking at a Property that has, 
say an enumerated set of values, and I don't remember what all the 
values are, nor do I remember exactly where in the many stacks of code 
the property is first documented. I find myself wishing each custom 
property has a comment field.


I suppose I could create a library of setProp and getProp handlers for 
every property I might like to document and document the values or 
constraints there. I suppose if I am doing that extra degree of work 
then I could enforce any constraints on the customer property in the 
getProp and setProp handlers, but that seems like a non-trivial extra 
amount of work just to remember that the custom property should only 
have values of X, Y, and Z.


Thoughts?

Re: Stack check-out/check-in

[Paul Dupuis via use-livecode]

If the could storage the stack is on has write access, the easiest 
mechanism is a file based flag.


When the stack is launched, if checks:

if there is a file  then
  -- the stack is already open, so exit
else
   put empty into URL ("file:"&) -- creates a empty file to 
mark as open

end

and  when the stack exists remove the file

on quit
  delete file 
end quit

Or something like that. I do not have LC open to check my code above.

need to prevent them from opening a 2nd instance of the stack on the other 
computer so that Dropbox (or other cloud sync service) does not create a

If there is not a way to tell, has anyone created some sort of stack
