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

Re: Converting from unicode to ASCII

I have a stack with an index. When a user clicks a line, a handler

We are now translating some stacks to other languages which require
unicode text. AWS recommends not using accented characters in file
names, so we need to translate the clicktext into plain ASCII.
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.

Re: text manipulation with Chinese characters (unicode): guide?
As mentions, Unicode in a field just works (there is a known issue with

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

Re: formattedRect, formattedLeft, formattedWidth of chunks
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.

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.

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.

Re: More Standalone Building Weirdness...
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.

I asked a similar question back on June 5th under the subject "Unicode
and languages" and Mark Waddingham provided the following answer
(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.

Mora Catalina permissions woes....
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. ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
Re: Platform Divergence
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.

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.

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! On 6/16/2020 6:28 PM, Paul Dupuis via use-livecode wrote: Hi Panos, Thank you very much.

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!

Unicode and languages
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.

Using the apple or android accessibility tools such as Screen reading, for example. I have been periodically looking at assistive technologies for LiveCode built applications on desktop platforms (vs mobile) over the years. Certain OS bases assistive tool like screen magnifiers do work as they are application independent. Unfortunately, screen readers and voice recognition tools generally don't work with LiveCode because the application independent tools look to act on OS native controls which most LC app don't use through out. With LC 9 and the FFI/Widgets it may be possible to build integration libraries for one or more of those assistive tools that require 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 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 '.

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.

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?

AW: Answer dialog enhancement...
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. -- Sent when the mouse is released after clicking -- pMouseButton specifies which mouse button was pressed on mouseUp pMouseButton dontaskagain "on" answer warning "Some message I may not want to see again." with "Cancel" or "OK" titled "A Message" put it into tAnswer put dontaskstatus() into tDontAskAgain dontaskagain "off" -- put "Don't Ask is:"&&tDontAskAgain &&"And button clicked is:"&&tAnswer end mouseUp command dontaskagain pActivate switch pActivate case "on" set the behavior of cd 1 of stack "Answer Dialog" to the long id of btn "DontAskBehavior" of this cd break case "off" set the behavior of cd 1 of stack "Answer Dialog" to empty delete btn "DontAskAgain" of cd 1 of stack "Answer Dialog" break end switch end dontaskagain function dontaskstatus if exists(btn "DontAskAgain" of cd 1 of stack "Answer Dialog") then put the hilite of btn "DontAskAgain" of cd 1 of stack "Answer Dialog" into tDontAskAgain return tDontAskAgain else return false end if end dontaskstatus BEHAVIOR BUTTON SCRIPT after preOpenCard if exists(btn "DontAskAgain" of cd 1 of stack "Answer Dialog") then set the style of btn "DontAskAgain" of cd 1 of stack "Answer Dialog" to "checkbox" set the autoHilite of btn "DontAskAgain" of cd 1 of stack "Answer Dialog" to false set the opaque of btn "DontAskAgain" of cd 1 of stack "Answer Dialog" to false set the threeD of btn "DontAskAgain" of cd 1 of stack "Answer Dialog" to false set the showBorder of btn "DontAskAgain" of cd 1 of stack "Answer Dialog" to false set the hiliteBorder of btn "DontAskAgain" of cd 1 of stack "Answer Dialog" to false set the height of btn "DontAskAgain" of cd 1 of stack "Answer Dialog" to 25 set the width of btn "DontAskAgain" of cd 1 of stack "Answer Dialog" to 120 set the bottomLeft of btn "DontAskAgain" of cd 1 of stack "Answer Dialog" to the bottomLeft of cd 1 of stack "Answer Dialog" else -- setup the templateButton set the style of the templateButton to "checkbox" set the label of the templateButton to "Don't Ask Again." -- create btn "DontAskAgain" in cd 1 of stack "Answer Dialog" -- reset the templateButton -- set the style of btn "DontAskAgain" of cd 1 of stack "Answer Dialog" to "checkbox" set the autoHilite of btn "DontAskAgain" of cd 1 of stack "Answer Dialog" to false set the opaque of btn "DontAskAgain" of cd 1 of stack "Answer Dialog" to false set the threeD of btn "DontAskAgain" of cd 1 of stack "Answer Dialog" to false set the showBorder of btn "DontAskAgain" of cd 1 of stack "Answer Dialog" to false set the hiliteBorder of btn "DontAskAgain" of cd 1 of stack "Answer Dialog" to false set the height of btn "DontAskAgain" of cd 1 of stack "Answer Dialog" to 25 set the width of btn "DontAskAgain" of cd 1 of stack "Answer Dialog" to 120 set the bottomLeft of btn "DontAskAgain" of cd 1 of stack "Answer Dialog" to the bottomLeft of cd 1 of stack "Answer Dialog" end if end preOpenCard before mouseUp pMouseButton -- if the target is the check box, check the box and do not pass mouseUp if the long ID of the target = the long id of btn "DontAskAgain" of cd 1 of stack "Answer Dialog" then set the hilite of btn "DontAskAgain" of cd 1 of stack "Answer Dialog" to not (the hilite of btn "DontAskAgain" of cd 1 of stack "Answer Dialog")

I’ll look into it because I wanted at one point to make an enhanced answer dialog as well. Bob S 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?? ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode

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.

Answer dialog enhancement...
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) ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
AW: specialFolderPath, Microsoft Window, and 64 bits
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.

return the 64-bit applications folder path. I will file an enhancement

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.

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.

At one point we looked at wrapping a C++ interface to the Mozilla code, but we don't have anyone here who has had the time to learn LCB and FFI, I know! We should make the time! It even comes with a command-line script (chardetect) which would allow to compare your detector with that one. However, on further digging it appears that this does not (as it stands) detect MacRoman which is obviously a key requirement here. MacRoman detection is a essential requirement. One of our selling points, since many Universities these days have people on mixed platforms, is that our tool is nearly identical across macOS and Windows to facility researcher collaborations, so we do have people sending files created on their Macs to Windows team members and vice versa, so we have to detect MacRoman and CP1252 on both platforms. There is a stale PR for that though <https://github.com/chardet/chardet/pull/5> so the method used here is obviously possible to extend to that. From what I have read the Python one is a python reimplementation of Mozilla's 'Universal Charset Detector' which, from what I have read, is/was pretty much state of the art - reading through the chardet docs (https://chardet.readthedocs.io/en/latest/how-it-works.html#single-byte-encodings is perhaps the most pertinent) it sounds like its single-byte detectors use 2-byte sequences to try and distinguish. There is a special case for Latin-1 (1252) which is needed because English text looks the same in a large number of encodings - this works by looking for curly quotes and other special symbols by the look of it. (The MacRoman addition in the stale PR above, is also a Latin-1 like special-case - which makes sense as Latin-1 and MacRoman are almost just permutations of each other). My general feeling is that if you already have a process which works to detect the differences between MacRoman and Latin-1, then it is likely largely equivalent to any other means which exists (the accepted answer here <https://stackoverflow.com/questions/4198804/how-to-reliably-guess-the-encoding-between-macroman-cp1252-latin1-utf-8-and> sounds like it pretty much sums up the situation!) so beyond fixing the bug(s) you found recently, you might find that there is nothing more you can do. And we arrive at the same place! Our review of our code, which failed to handle a particular MacRoman detection, and comparing to other encoding guessing algorithms, turned up a couple issues - all fixable in our code, and only one was a encoding guessing issue. In our guessEncoding routine, there was a misspelled variable that was preventing the detection of MacRoman from line ending comparisons from working properly. I'm not sure how this got past our QA, but - as you know - sometimes things do and it did. With that fixed, we getting accurate detection of C1252, MacRoman, ASCII, UTF8, UTF16 BE/LE, and UTF32 BE/LE on our suite of about 30 different test files. We also ran into an edge case of Mac cr (ASCII 13) line ending in UTF8 or UTF16 file needed an adjustment to convert the line ending to linefeeds. So at this point our code is detecting the encoding for and reading text files into LC with a pretty high rate of accuracy. For anyone else needed such code, I will try to pulling into a single library and somehow make it available. All I will ask is that if anyone does us it and improved upon it to share the improvement back. ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
Re: Guessing the encoding of a test file...
Nope. The reason I refer to the routine as "guessEncoding" is that I absolutely know that it is a "guess" based on the presence of nulls and other bytes for UTF files and by statistical sampling for various characters for MacRoman vs CP1252. We also offer a optional way for the user to pick the encoding IF THEY KNOW IT (or I suppose they can keep guessing until they get it right), I'll say it again, I was looking to see if ANY one else had implemented a guessEncoding routine and was willing to share of license for comparison to my own in hopes of either concluding mine is the best it can be OR learning something someone else is doing that improves it a little bit.

Because text encoding is intrinsically arbitrary—see also: the many variations on extended (8-bit) ASCII, the various mutually-incompatible versions of EBCDIC, etc ad nauseam. Seems to me, therefore, that in the general case, human involvement is an *unavoidable necessity* in determining which encoding an arbitrary text document uses. So the goal of any encoding-ID algorithm should *not* be the impossible task of determining that encoding *without* human involvement. Rather, the goal should be to *minimize* that human involvement, make that human involvement as *simple and painless* as practically feasible. So, here goes with some semi-random rambling… Pretty sure the best, most nearly bulletproof way to ID a document's text-encoding involves applying that encoding to the bits of the document, and showing the resulting character-sequence to a human. If there's more than one possibility for the document's encoding, apply all of the possible encodings, and show a human all of the resulting character-sequences. I'm thinking that a good way to do this might be to put up N different text fields in a window, with all of the text fields controlled by one scrollbar, and the human clicks on all of the fields whose content looks good to them. Or maybe the human clicks on all the fields whose output looks *bad* to them? Whichever way works; as long as there *is* some human judgement in there somewhere. Can we assume that once a particular document's text-encoding has been identified, that *all* documents which came from the same source as that document use that particular encoding? If so, that might simplify the continuing workflow; tell the software "This document came from Source X", and the software then uses whichever text-encoding it associates with that source. Even if there's more than one such text-encoding in play, that's at least easier to work with than having to sort thru an arbitrarily large number of text-encodings. Is it possible to tell the software "hey, no character in $ThisSetOfChars will ever appear in this document"? If so, the software should be able to rule out any encoding which ends up putting one of the Forbidden Chars into the decoded character-sequence. Given human error, it may be that the human's input ends up ruling out *any possible* text-encoding. Prolly a good idea to use something akin to fuzzy logic rather than strict Boolean operations. ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode

Re: Guessing the encoding of a test file...
To Sean and Bob, Thank you for your replies. I may not have been clear enough in my original post: We make and sell an App for macOS and Windows. It's uses around the world by researchers (not a lot of them as it is a niche product) on their computers. The research applications allows input of data from text files. The sources of those text files are from various source those researcher have. It would negatively impact our competitiveness in our market if we forced the users to convert their data all to some specific text encoding, so we need to try to "guess" the encoding of those text files. There are many published algorithms for doing this and we have a past contractor of ours take a "best practice" algorithm and create a LCS "guessEncoding function. This replaced a previous guessEncoding function we had that from Richard Gaskin, which while quite good, did not cover as many test cases and the newer more robust one. My main question to the list was: Has anyone out there ALSO written a guessEncoding function they might like to share or license? Why did I ask this? Because I am interested in comparing the accuracy of our current handler to any other that may be available as, users being users, we recently have a user reveal a bug (mis named variable) in our current function that meant it was missing certain edge cases ( and this user has hundreds of text files that need this edge case to be properly recognized as MAcRoman encoding. So that bug has been fixed, but I am still interested in comparing any other giessEncoding routines to our current one to see if we can do better that we current are. To Mark, As always, thank for reading and responding Mark. We're actually doing what you suggest. We had a set of QA test cases (text files in many different line endings and encodings), some intended to fail (such as Windows Code Page's we don't support). We're expanding these and doing a review on macOS and Windows with our app. Ones that fail, that we think shouldn't fail, we will step through the code to see why they fail and if our algorithm can be further enhanced. I can's foresee any algorithm tweaks we can't code ourselves that we'd need LC or USE-LIST assistance for. Back around LiveCode 7, Fraiser said, in response to some correspondence I had with him, that he would consider creating a "guessEncoding" to go along with the Unicode Everywhere work and the new textEncode/textDecode functions. I do understand the reluctance, as a business, to do so, as inevitably there will be some instances where it guesses wrong. Other than LC adding a guessEncoding function using some open source library, I would say the area where LC could be the most help would be with this enhancement https://quality.livecode.com/show_bug.cgi?id=22391 I am under the, perhaps false, impression that isoToMac and macToIso are sort of viewed as functions that may become deprecated and no longer updated in the future.

Re: Guessing the encoding of a test file...
Users of our application may use text files any whatever encoding their local system creates them in. We can not tell them to only create such files with a specific encoding. So, we need to detect the encoding of the text file the user selects. As I mentioned, I have an LC script that implements a encoding guessing algorithm. I am looking for an alternative or better one if someone out there happened to have created one they might like to share or license.

I can still wish it wasn't so though... I am working on a new tool requested by a customer. The crunching and analysis of the research data coding is simple compared to the UI which will probably take me 10 times as long to code and get to look and function "right" on macOS and Windows. ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode

I constantly run into things like we make a button with a label that fits on one platform and then on another the label is too long or a filed is sized to display x lines on this platform but on that platform the line sizes are different! G! It really is infuriating at times. I would love the IDE to help, even by things like showing a bounding box for a button label that takes all platforms checked in the standalone setting into account.

I think the conflict comes from the assumption that having the default be '(Text)' (or the font underlying them) is the correct thing to do. If the field allows user-settable styling (even just font), then I'd suggest that it doesn't need to use the 'default system font for the platform' and you can just choose a sensible default - i.e. it isn't a UI text area from a HIG perspective, it is a user styled text area/document area. As a comparison, TextEdit defaults to Helvetica and WordPad defaults to Calibri or Times New Roman (depending on version I think) [ I can't remember what Notepad uses on Windows 10, something horrendously ugly and bitmap based still, probably! ] My point of view here is mainly motivated by the following... A couple of weeks ago (or maybe longer?) Klaus noticed a really strange problem with text extraction from a PDF printed using LiveCode on macOS - specifically digits did not extract as digits (they looked absolutely fine). [ He seemed to get quite hot-under-the-collar-about-it, but they may have just been his Germanic enthusiasm ;) ]. Changing the font to Courier or Arial solved the problem - digits could be copied as digits again. It wasn't until I ran an internal tool I wrote for Kognition many moons ago on the generated PDF that I figured out what the cause was. The effective font of the offending field was '(System)' - this came out in the PDF as '.SFNSText'. (Note: I still don't quite know why it munges digits - my guess is that it doesn't have a traditional CMAP table). This is a font you won't find listed in the fontNames, nor (I don't think) In FontBook or anywhere else. It is a seemingly highly specialized and custom crafted font designed only for screen display in the macOS UI. Indeed, if I interrogate the NSFont object we get internally when requesting the font for (Text), I get '.AppleSystemUIFont' - which is similarly not appropriate for what you want. TL;DR version: Theme fonts '(...)' should only be used for 'fixed' UI display - they won't print in the same way and cannot be chosen in the same way by name. For text that might be printed, or where the font can be chosen by the user, you should choose sensible default fonts similar to those of the basic apps for styled text entry on the platform the program is running on. Hope this helps, Yes, it does. Lacking a detailed technical understanding of the ridiculous complexity of the macOS (or Windows for that matter), is one reason we used/use HyperCard, SuperCard, MetaCard, Revolution, LiveCode for the past 25+ years for our app development. It *SEEMED* like a reasonable attempt at HIG compliance to set the fonts of our objects to the special names and also *SEEMED* like it was then reasonable to want to show what font was selected in a menu, but it is absolutely true that I was assuming that "(Text) became Segui UI on Windows and Calibri (or whatever) on macOS and NOT something like .AppleSystemUIFont! So, we'll revert our code back to the classic conditional of: switch platform() case "Win32" set the textFont of fld "X" to "Segue UI" -- or whatever seems appropriate set the textFont of fld "Y" to "Segue UI" ... set all the rest of the objects break case "MacOS" set the textFont of fld "X" to "something" break case "next platform" etc. We went down a rabbit hole where, without knowing better, it seemed that the above could be replaced with set the textFont of fld "X" to "(Text)" set the textFont of fld "Y" to "(Text)" etc and eliminate the switch statement entirely. set ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode

My goal was to be able to read somewhere like in the dictionary or user guide or run some code to find out what the actual font is for each of the "specials" on Windows and macOS. To be accurate, your request / report is entirely different from Richard's philosophical question. True. I thought is was on the same topic though, so I responded. You want 'the effective fontName' of a chunk / object to return the actual name of the font which the system is using to render the glyphs - which would be huge departure from its current (very LC-specific) meaning. Also I did not declare it a documentation issue (because it is not). My exact wording was: "I suspect it is possible to get the names of the actual system-provided fonts - but there is no facility in LiveCode for this at present. Please file an enhancement request for this ability." My apology for mis-characterizing what you said. Yes, I interpreted that a "enhancement" for what I wanted, could be delivered by a documentation request and I thought that documenting the fonts corresponding to the fontNames engine directives would be easier that any sort of technical change to the engine - another assumption based on observation of the rate of documentation fixes vs the rate of engine technical fixes. Both are impressive for the size of the team, but doc fixes do seem to out pace technical changes since they are generally easier. This is precisely because the mapping is not fixed. Both Windows and Linux allow the user to change the relevant fonts used at the system level, and macOS uses highly-specialized UI fonts for the purpose (as Klaus and I recently discovered when he was having a problem with text extraction from PDFs printed from LC!). True, and this point negates that a documentation approach would solve what I was looking for. So, my bad for being short sighted in asking for a documentation enhancement. That was a mistake, and I see that now. My current point of view is that this need represents an edge-case, and it is more than likely that changing your approach to whatever it is you believe you need it for means you won't... So, an important question is here why do you need to know the actual font being used when an object is set to render with one of the meta-(theme)- fonts? So here is the simple use-case I ran into. We have a field with an editor toolbar for rich content editing in an app. The field is set to (Text) upon start up, as in: set the textFont of fld "X" to "(Text)" So that the font is initially in the appropriate default font for the platform the app is running on. In the toolbar we also have a Font pup menu with the available fonts listed for the user to change the font they want in the field. It is the UI standard that such a menu SHOW the user the currently selected font. My problem, if I try to follow platfrom UI guidelines by setting the text field's font to (Text), I then can not - say get the effective textFont of fld "X" - to find out which Fontname in the UI standard popup font menu should be checked as the current font. Now in the scheme of our own list of App bugs to fix and enhancements to build, whether the Font menu precisely corresponds to UI standards or not is not at the top of our list, but it still would have been nice not to have conflicting UI standards issues: Using textFont = (Text) gets me the appropriate fonts by platform, but then I can show what the selected font for the field is in a standard UI font menu.

The work is not in revZip - I've worked with it a lot. And, as Richard said, the work is not with revXML - I've used that a lot too and it work very nicely for parsing XML quickly. The work is entirely in mapping those Microsoft XML for Powerpoint elements that can be mapped to corresponding LC elements and mapping all the properties (colors, sizes, etc.) and coding those mapping. A lot of Microsoft stuff can be thrown away. I don't need it as a presentation, just the information in the file. So transitions, effects, presentation timings, etc, can all be ignored.

Re: Powerpoint to LiveCode
Hi Rick, Powerpoint can export to HTML, and while I have not looked at Keynote's HTML export, I think you would be just trading one problem at file parsing for another. Tools like PowerPoint and Keynote export to HTML with CSS, so you can't just: set the htmlText of field x to URL tPresentationFile You'd still have to parse the HTML/CSS into something LiveCode can understand. Again, I know how to do this. My questions is: Has someone already done it or even part of it?

Re: Progressive Web App (PWA)
The answer is EITHER: Use LiveCode SERVER to generate the HTML5 and CCS for the app and layer your own Javascript into it [Much more work, but you can deliver exactly the front end you want - you have to keep track fo what HTML, CSS, and Javascript you use is standards-compliant) OR Use LievCode HTML to deploy your stacks/App as an HTML/CSS/Javascript app.(lLess work, but you are limited to what the HTML builder for LiveCode can produce [mostly, I think there is someone on this list who has posted many example of extending the generated web app with supplemental javascript]) However, in my opinion "intended to work on any platform that uses a standards-compliant browser."

Re: Does any one know what Player "intervals" actually are?
Hi Martin, Thanks for you post/reply. As we are updating our application, all times are being stored in seconds (real number) and converted to and from intervals as needed. Just like you in your application. The old version of our application stored data in user document files. In these files, some data was stored as only intervals, without a timeScale to properly translate back to seconds for newer frameworks. I was hoping there might be some rules I could apply to determine how these interval (only) values could be converted to times without a timescale value. In doing research and contacting LiveCode support, the answer is: They can not (or at least not practically). The only way would be to open the exact same media file in a helper app that is built in an old version of LIveCode that uses Quicktime to get the original Interval for each media file referenced in our user documents that needs intervals converted. This is impractical as we can not expect the installation of Quicktime under Windows any more and older LC helper app will not run under macOS Catalina to name just a few of the obstacles. The table of timescales in my original post is also distorted as many of the media files are the exact same clip, just encoded in another format. I am sure if I sampled a wider variety of clips I would see a much wider range of timeScales. Lastly, my inquiry was also looking to actually understand what "intervals" really are, mostly out of curiosity and interest. I am still curious as to what exactly "intervals" are. LC support just says that they get them from the media frameworks and pass them along.

Does any one know what Player "intervals" actually are?
Or even more specifically, does any one know what player object "intervals" (the values for currentTime, startTime, endTime, timeScale, and duration properties of a player) actually are? Are they frames? Something else? And does anyone know why they vary by Media Framework (i.e Quicktime vs Apple Video Foundation vs DirectShow) For example, the same MP3 file under Quicktime (macOS or Windows) has a timeScale of 600, and under AVF a timeScale of 44100 and under DirectShow a timeScale of 1000. What's more if you get the duration and the timeScale and convert to seconds, the different frameworks give (slightly) different values (largest difference is 3s on a 2m45s MP3) For example, look at the lengthy list of data below: This is timeScale and duration for different file formats by media frameworks.

So, you when you speak of a PWA written in LiveCode, you are either talking about using LiveCode server to generate HTML5, CSS3 and Javascript that forms some application?

Re: the fontnames and special names like (Menu)
Exactly, but this does not answer my question, which is: if I set the textFont of an object , say a button to "(Menu)" and the look at the effective textFont of that same object, I get "(Menu"), so how do I find out what the actual font really is? For example, the default field font on Windows 10 is "Segoe UI", but if I set a the textFont of a fld to "(Text)" and the get the effective textFont of that same field, I get "(Text)" when I would expect to get "Segoe UI".

Running LiveCode Standalones under Crossover on Linux
Hivemind, I have a user who runs the Windows version of my software on Linux using Crossover. Our prior releases all have worked fine. Those releases were build under LiveCode 6.7.11 We just went to a new release built under LiveCode 9.0.5 and this user is getting menus and dialog boxes with no text (none at all) in them. Any chance that someone in the larger LiveCode community has seen this issue and knows what may be going on? We test under Windows 7,8,10 and under macOS 10.9 to 10.15, but not on Linux running Windows emulators. We don't have a Linux system here to even test on, but I'd like to try an help the person. ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
