Re: Datagrid internal error
32,767 is the max for width as well. If there are enough columns it is possible that the DataGrid is rendering a group that exceeds this limit and hence the error. The DataGrid works around the limit when rendering rows, but not when rendering columns. I suppose a quick test would be to create a DataGrid with 330 columns that are at least 100 pixels wide and see if you get the same error. -- Trevor DeVore ScreenSteps On Mon, Aug 8, 2022 at 12:36 PM Ralph DiMola via use-livecode < use-livecode@lists.runrev.com> wrote: > Paul, > > The max height of a field is 32,767 pixels.

You can set the `related table joins` (or just `joins`) property of a SQL Query Object.

Automating LiveCode builds with Github Actions?
Hello, I would like to automate the following sequential steps using Github Actions and I'm wondering if anyone has experience automating LiveCode with Github Actions that they could share. 1. Open a stack in LiveCode and send a message to it. This would be for building a Levure application. 2. Build an MSI file using Wix 3. Build an exe installer with Inno Setup. The end result would be the ability to create MSI and exe installers from a LIveCode application from a central location (Github) either manually or as part of another workflow. -- Trevor DeVore ScreenSteps ___ 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 have successfully built Windows executables on macOS three times with 9.6.4. The only issue I experienced was with tsNet business.

If you look at the helper.yml file you see this: ``` libraries: - filename: undoManager.livecodescript frontscripts: - filename: field_edits_undo.livecodescript autoload: false ``` What that means is that you should `start using stack "undoManager.livecodescript"` when your app starts up and `put there is a stack "field_edits_undo.livecodescript" into tStackIsNoInMemory`. (Note that it is left as an exercise to the reader to determine the full path to those stacks when being used in your app.) The `field_edits_undo.livecodescript` stack just needs to be in memory so that `undoManager.livecodescript` can insert it into the front whenever the user is editing text in a field. -- Trevor DeVore ScreenSteps www.screensteps.com ___ 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

Changes to revsecurity.dylib in LC 9.6.2?
This is a question for the LIveCode engineers. Did anything change with how revsecurity.dylib is built for LC 9.6.2 compared to previous versions of LC? I just built my application using LC 9.6.2 RC-5 in order to test. I'm packaging the app with Levure, which uses the Standalone Builder. The app works just fine when built with LC 9.6.1 RC 1 and it works in the LC 9.6.2 RC-5 IDE. The app also works when run on Windows. But when I run the application on macOS encryption calls fails with the error "ssl library not found". Looking at the Console logs on macOS I see this error default 12:49:42.154433-0500 kernel /Users/xyz/path-to-app/Contents/MacOS/revsecurity.dylib: Possible race detected. Rejecting. A search for "Possible race detected. Rejecting" lead me to this thread where an Apple engineer asked if the file that was loading is "built against a modern macOS SDK (10.9 or later)?" (there is no answer yet). https://developer.apple.com/forums/thread/677250 I'm going to do some further testing where I swap out the old revsecurity.dylib and also try running the app prior to signing and notarization. I'll provide an update once I am able to run those tests. -- Trevor DeVore ScreenSteps www.screensteps.com ___ 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

We also agree that they shouldn't try to write solutions for all possible ways that someone may need to distribute a standalone. My 2 cents is that LiveCode should provide a way for 3rd parties to expand on what happens when a standalone is being built. This is more than just turning off an option. Turning off an option would introduce an absence of behavior. I'm suggesting the addition of behavior that can occur during key points of the standalone building process. Perhaps all use cases can adequately be handled with the messages that are already sent once when a standalone builder finishes (e.g. savingStandalone and standaloneSaved). But, perhaps the standalone building process would be better served with additional, more granular callbacks, and maybe those callbacks are sent to a target other than the stack being saved. That is what I would like to be considered when modernizing the Standalone Builder. -- Trevor DeVore ScreenSteps www.screensteps.com ___ 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

For example, when packaging an app with Levure you can add in Helpers to further customize the output generated when packaging an app for distribution. In addition to handling signing, notarizing, and stapling, one can generate a DMG using DropDMG, create an InnoSetup installer script, creat a WIX installer script (creates a Windows installer file that IT departments love), etc. LiveCode doesn't need to build support for all of these in the SB, but it should provide hooks so that plugins can further customize the process. -- Trevor DeVore ScreenSteps www.screensteps.com ___ 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

The scrolling can be improved further by using the scroll event values provided by the operating system. On macOS it is simple enough to get the true scroll values from the scroll event using NSEvent.scrollingDeltaX and NSEvent.scrollingDeltaY. It is possible to get those values using LCB as demonstrated in the mac_scroll_wheel.lcb extension that is included with the DataView control I've made available. Here is a link to the source code: https://github.com/trevordevore/levurehelper-dataview/blob/develop/mac_scroll_wheel.lcb Anyone who is interested and running macOS can download the compiled version of the extension and test it out in the sample stack. 1) Visit the following link and click the "Download" button https://github.com/trevordevore/levurehelper-dataview/blob/develop/mac_scroll_wheel.lcm 2) Then run this in the Message Box and select the .lcm file to load it: answer file "Select Extension";load extension from file it;put the result 3) Add this script to any field you want to test with: on rawKeyDown pKey if pKey = "65308" or pKey = "65309" then set the vscroll of me to the vscroll of me - item 2 of macCurrentEventScrollValues(the effective linesize of me) else pass rawKeyDown end if end rawKeyDown On my computer I see the best results in the test stack from the bug report using this method. Ideally any engine improvements would tap into the scroll wheel values provided by the OS. -- Trevor DeVore ScreenSteps ___ 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

The Levure app packaging scripts will do this when you package up an app. So you get the benefit of script only stacks during development and the protection of encrypted when you distribute. -- Trevor DeVore ScreenSteps > ___ 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
Shoudl LiveCode be calling exit() when terminating a Cocoa app?
Hi all, This is probably a question for someone from the LC team who works on the engine. If anyone else is familiar with how LC quits on macOS please chime in though. Scenario: I am running tests with the Sparkle.framework on macOS (which I already use) with the goal of silently and automatically downloading updates for an application that will be installed the next time the user quits the application. You can see similar behavior in apps such as Slack. Sparkle support: Sparkle supports this type of behavior if you set some properties. It checks and downloads an update to the local cache and then installs the update when the hosting app graceful terminates. Problem: I have confirmed that Sparkle downloads the updates to the cache but the update is never installed when I quit. I'm wondering if this is due to the use of exit(t_exit_code) in -applicationWillTerminate in mac-core.mm. Additional Info: While researching the problem I found an issue in the Sparkle Github project which had some interesting information in it. The author of the issue mentions that the app terminates by calling exit(0): https://github.com/sparkle-project/Sparkle/issues/1047#issuecomment-298029934 The maintainer says that Sparkle only supports graceful termination via Cocoa notification: https://github.com/sparkle-project/Sparkle/issues/1047#issuecomment-298041354 So I started looking through the LiveCode source code to see how LiveCode terminates an app when `quit` is called in LiveCode Script. If found mac-core.mm which has the main run loop which calls `[NSApp terminate: self];` when it is time to quit: https://github.com/livecode/livecode/blob/develop/engine/src/mac-core.mm#L360 That looks right. But farther down in applicationWillTerminate I found a call to `exit(t_exit_code)`; https://github.com/livecode/livecode/blob/develop/engine/src/mac-core.mm#L416 I'm wondering if that call to exit() is what is causing problems as my understanding is that exit() immediately causes an app to terminate. Perhaps exit() should only be called if t_exit_code > 0? -- Trevor DeVore ScreenSteps www.screensteps.com ___ 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

Extensive testing has been done on macOS and Windows. The Levure framework has the file_system helper which does most of the work for you on Windows, macOS, and iOS so you can look at that code for guidance. You can find the source code at the link below. I will link to specific code examples below as well. https://github.com/trevordevore/levure/tree/develop/framework/helpers/file_system There are three parts that make up a working solution - registration, processing requests, and triggering requests. Here is a description of each. Hopefully I'm not missing anything. I coded this a long time in Levure and haven't had to think about it much since. 1. Tell the operating system your app can handle a url protocol. ## Windows You will need to modify the registry. Here is a link to the command that updates the registry in the file_system helper: https://github.com/trevordevore/levure/blob/develop/framework/helpers/file_system/file_system.livecodescript#L193 The command uses levureStandaloneFilename(), a framework function that returns the full path to the standalone application. Just replace that with a similar function so that you can add the full path to your app to the registry. This command can be called each time your application launches if you want to make sure that the version the user just launched is the one the OS will send a url request to. ## macOS and iOS Add the URL protocol you want to add to your Info.plist file. It will look something like this (taken from the ScreenSteps Info.plist file) : http://www.apple.com/DTDs/PropertyList-1.0.dtd;> ... OTHER STUFF CFBundleURLName ScreenSteps URL CFBundleURLSchemes x-screensteps-app screensteps screensteps-4 2. Process URL requests sent by the OS to your app ## Windows Process `relaunch` command, extract command line arguments looking for url. `relaunch` is handled within main Levure script: https://github.com/trevordevore/levure/blob/develop/framework/levure.livecodescript#L46 The file_system helper processes the parameters though: https://github.com/trevordevore/levure/blob/develop/framework/levure.livecodescript#L46 ## macOS Process the appleEvent with pClass "GURL" AND pID "GURL". https://github.com/trevordevore/levure/blob/develop/framework/helpers/file_system/file_system.livecodescript#L111 ## iOS Process `urlWakeUp`. https://github.com/trevordevore/levure/blob/develop/framework/helpers/file_system/file_system.livecodescript#L65 3. Triggering requests Triggering requests is as simple as using your custom protocol in an tag in your web page.

There are two ways you can assign the behavior: 1) Define the behavior within the script-only stack itself. script "My script-only stack" with behavior "A Stack Name" Just make sure that the stack being assigned as the behavior is loaded into memory when you load the script-only stack. 2) After loading the script-only stack into memory set the behavior property.

Spell Checker
Hi folks, FYI I've published a Github repo with a spell checker. The code is code I've been developing for a spell checker replacement in apps I develop for macOS and Windows. It uses NSSpellChecker on macOS and Hunspell on Windows. If some kind soul wants to compile a Hunspell 1.6.2 .so library for Linux the it would support Linux as well (I don't develop for Linux). The url where you can go to learn about it, download it, or contribute to it <—-! is here: https://github.com/trevordevore/spell_checker Instructions for using it in your LiveCode app are at the bottom of the page. The latest release, along with the LCE files for installing some extensions that are required, can be found on the Releases page: https://github.com/trevordevore/spell_checker/releases For those adding the spell checker to a Levure application no need to install the extensions. The repo is in Helper format and you can add the folder to the Helpers folder in your app. Just make sure you are using the newly released version 0.9.4 of the Levure framework in your app which allows Helpers to define where .dll, .so, .dylibs, and the like should be packaged up when building a standalone. Release notes for each version can be found here: https://github.com/trevordevore/levure/releases P.S. I've updated my signature with links to my Github repos that relate to LiveCode and LiveCode Builder.

To clarify, my guide wasn’t really script length. It was scripts in buttons that only called a handler in the group, card, or stack script (which would be SOS). So something like this: on mouseUp pBtnNum if pBtnNum is 1 then uiDoSomething end if end mouseUp It seemed counter productive to have SOS stacks for every button. After a couple of rounds of refactoring I’ve changed my approach. I only use SublimeText to work on code and when searching for handlers the ones stored as part of the stack wouldn’t show up. In the above example I now leave the button script empty and move the mouseUp to the group the button is in. The mouseUp in the group branches based on the target. This approach allows me to do a search and replace in all code within SublimeText if I need to. Since I organize the UI into groups of controls with their own behavior scripts no single mouseUp handler becomes too unwieldy. It isn’t like there is one script that is branching for every possible button click on the card. Regarding the question of whether or not you would want to use Script Tracker with Levure - Levure doesn’t really care :-) Levure has excellent support for workflows that use script-only stacks. If you choose to it can encrypt all of them when packing up a standalone. But it doesn’t require it at all. Levure will happily work with any sort of stack file you add. For example, one could add their existing stacks to a Levure app and start leveraging the available Helpers (spell check, notary, auto update, installer builders, etc.) without extracting any scripts to script-only stacks. - - Trevor DeVore ScreenSteps > ___ 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
Testing spell checking with Hunspell Extension
Hi Everyone, I've been working on an LCB extension which wraps the Hunspell library. This library is used for spell checking. https://en.wikipedia.org/wiki/Hunspell I have finished a first pass that works on my Windows 8 and 10 installations with LiveCode 9.6dp-4 32 and 64-bit. I would be interested in having some other people test it out to see if it works for them. I'm hoping that those with Windows versions of LiveCode that support LCB could test it out and see if everything works in the test stack. The Github repo is at the url below and there is a section titled "Testing" which explains the steps. https://github.com/trevordevore/lc-hunspell The extension is available under an MIT license and it would be nice to have some others look over the code, make some improvements, compile a Linux .so, etc. The repo includes a French dictionary for testing. There are lots of dictionaries available for Hunspell, however. I've downloaded dictionaries from https://extensions.openoffice.org before. I also came across this github repo today which has a large list of 90 compatible dictionaries: https://github.com/wooorm/dictionaries -- Trevor DeVore ScreenSteps www.screensteps.com ___ 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

Correct? Yes. The data and keys are not UTF-8 encoded.
Desired? No.
Try encoding the keys and data as UTF-8 before passing to arraytojson.
Arraytojson() uses the mergJSON external and requires UTF-8 data.

You can refer to the following report I filed on the current state of JSON
in LiveCode (which is not good). In my work I use both the JSON Library and
mergJSON as described in the report.

Focusing on a field if you need to is simple and can be achieved using one line of code. Plus, by coding it you don’t have to worry about the wrong field obtaining focus if you change the layering order of controls later on. - - Trevor DeVore ScreenSteps > ___ 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

Using Shift + Cmd + 1 as a menu short in LiveCode
Hi all, I tried assigning Shift + Cmd + 1 to a menu shortcut in LiveCode but LiveCode insists on using Cmd + 1 instead. I would like to insist that it use Shift + Cmd + 1, just as I entered it :-) Anyone know how to trick LiveCode into using what I entered? I know Shift + Cmd + 1 can be used as XCode uses this key combination for a shortcut in the Windows menu. I'm currently testing on macOS 10.14. Simple Recipe: 1) Create a new stack 2) Open the Menu Builder 3) Create a new menu bar 4) Select File > New and check the Cmd and Shift checkboxes then type 1 into the shortcut field. 5) Test the menu.

I appreciate you taking the time. You are right though, I'm not particularly fond of hacks in the field control when the field is being used as a text editor (which is my use case). Here is the reason why. When writing a text editor it doesn't take long for the hacks to get out of hand and you end up with a control that becomes hard to add features to and hard to perform maintenance on. In addition, the field stops behaving or looking the way a user expects a text editor to work. For example, if I were to add the hack for displaying nested numeric lists I would need to add a hack for keeping track of other list styles the user might select elsewhere in the field. I would also have to deal with incorrect indentation for multi-line list items because the text would appear flush with the list numbers. Then I would need to add a hack to handle deletion of characters properly since the numbers are part of the actual text rather than an ornament that is added by the engine. There is this ripple effect which always makes me wish I hadn't implemented the hack :-) -- Trevor DeVore ScreenSteps www.screensteps.com ___ 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

[macOS] Notarization, hardened runtimes, LCB, and executables
Hey list, I just spent a good portion of the last few days troubleshooting some notarization errors I started receiving. I'm going to document what I did so that someone else out there might benefit. # The Original Problem I have been notarizing my application for a while now without any issues. This week an error message started coming back from Apple: "The executable does not have the hardened runtime enabled.". (I found the error my looking at the log file that Levure creates when packaging an application. It contains the responses from the Apple notarization service which in turn contain a url pointing to a detailed report of why an app fails notarization.) A search led me to the following web page which tells me to pass the `--options=runtime` to the `codesign` command line call to fix this issue. https://developer.apple.com/documentation/xcode/notarizing_macos_software_before_distribution/resolving_common_notarization_issues?language=objc Easy enough. I updated the Levure packager script (see links below) that packages up applications so that it will automatically sign the app bundle and the files inside using this option as part of the packaging process. I ran into some problems when trying to sign the Sparkle.framework that ships with my app. It has an Autoupdate.app app inside of the `./Content/Resources` folder which in turn contains a `filop` executable that wasn't being signed. I had to spend some time making additional improvements to the Levure packager script so that it would dig down into the necessary folders looking for files that need signing. After making the necessary changes so that all files were properly signed application was successfully notarized by Apple. Phew! # The Problem Caused By The Solution To The Problem Unfortunately the solution of hardening the runtime uncovered yet another problem. My application started throwing an error when trying to load some LCB code. The LiveCode engine was unable to bind to some Foreign Function Interface definitions in one of my LCB files. The problematic binding is defined as follows: private foreign handler C_CurrentKbdLayoutInputSource() returns ObjcId binds to "c:Carbon.framework>TISCopyCurrentKeyboardLayoutInputSource" # Entitlements Since none of my code had changed I looked in the Console application to see if there were any error messages. I saw a message in the console about my app needing the `com.apple.security.automation.apple-events` permission so I chased that red herring for a while. As part of my research I came across entitlements. Entitlements are a way for you to tell macOS that your app needs special permissions. I've used them before in the Mac App Store but not for apps used outside the store. The following web page lists the entitlements that are available for a macOS app: https://developer.apple.com/documentation/bundleresources/entitlements/com_apple_security_cs_disable-library-validation?language=objc As I scanned through the list a couple of the options caught my eye. For instance, `com.apple.security.cs.allow-dyld-environment-variables` sounds like something that might apply to LCB. My first test involved assigning a number of entitlements to my app to see if it would launch. Sure enough it did. I then started removing entitlements until I found the smallest list that would work. Here is the final entitlement file that I came up with that allowed my LCB code to run without causing an error or causing a spinning beach ball of doom: http://www.apple.com/DTDs/PropertyList-1.0.dtd;> com.apple.security.cs.allow-unsigned-executable-memory com.apple.security.cs.allow-dyld-environment-variables The above XML goes in a file with the same name as my app with an `.entitlements` extension. That file is added to the `./Contents/Resources` folder of the app bundle and Levure then uses that file when signing the app. Learn more: https://github.com/trevordevore/levure/wiki/How-do-I-include-additional-files-and-folders-in-my-application-builds%3F#copy-files-into-the-contentsresources-folder-of-your-packaged-macos-application This same entitlements file also fixed a problem I was seeing with the browser widget in my app. It too would lock up. # Mostly Smooth Sailing With a hardened runtime and the proper entitlements in place my LiveCode app was being notarized successfully AND launching. Good times! Feeling confident I decided to merge in a branch I had been working on that included an executable created using pyinstaller so I could send it off to QA. That didn't go well. After packaging up the app I did a quick test to make sure the new feature worked on my machine. It didn't. The error message was about some code trying to execute that wasn't signed and some note about library validation or something or other (I didn't write it down). After some searches I found some other people who experienced similar problems with executables built with pyinstaller (and some other installers I believe).

I love how I can silo my own work on features as well as the flexibility to see detailed history of changes throughout the life of my application. I use the Git commit notes and the ease with which you can review changes in those commits a number of times when trying to track down at what point a bug was introduced. Here is an example of how I silo work I'm doing right now. If you looked at my Git repo earlier today you would see the following branches: - master - develop - tkd-htmltidy - tkd-remove-answer-types - tkd-mammoth - tkd-hires-annotations `master` always has the release version of the code. `develop` is code that has been developed, tested, and is ready to go into the next release. I will create builds from this branch to send to customers who want early access to a feature or bug fix. All other branches are features that are being worked on but which are not finished and require more testing. Some of those branches exist for an afternoon. Some last for a month or more. Today I merged in `tkd-htmltidy` and tkd-remove-answer-types` into `develop` as they were finished and are ready to send to customers who need early access. When I squashed and merged those branches in there were a number of changes which had been made in the develop branch since I had started `tkd-htmltidy`. Those changes were seamless blended together without any problem, even though there were changes changes made in some of the same files. In addition, because I squashed the merge, all of the changes that went into the addition of HTML Tidy are seen as one commit in my `develop` branch. I made dozens of commits during development but was able to make one clean commit when I was all done and ready to merge the changes with the main code branch. This makes for a clean history that is easier to review later on. I will continue to work on the tkd-hires-annotations and tkd-mammoth branches as they aren't done yet and require more revisions. But once they are ready I perform the same squash and merge. If I want an internal tester or a customer to test those features out before they are ready I can do that too. I can use the Git rebase feature to bring in all changes to `develop` that have been made since I created a particular branch. That means the tester is using the latest version of the app along with the new feature I'm working on. One last example. Let's say that a nasty bug turns up while I'm working on `develop` and need to get a release out to customers right away. I can go to master, create a new branch from that code, make the fix, and package up a new installer. I can merge that fix into `develop` as well so that it will be included in a future update. I think the scenarios I describe above are my favorite reasons for using Git as they make my daily development and management of the code easier. -- Trevor DeVore ScreenSteps www.screensteps.com ___ 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

For PrintKeys you can get to the script that has it in one of two ways: edit script of behavior of behavior of selobj() edit script of stack "RevDataGridLibraryBehaviorsDataGridButtonBehavior" This is the PrintKeys handler: ``` command PrintKeys pArray if pArray is not an array then put sDataArray into pArray put _PrintKeys(pArray) end PrintKeys ``` And here is the _PrintKeys() function: ``` private function _PrintKeys @pArray, pDimension if pDimension is empty then put 0 into pDimension local theKeys, theText, theTempArray put the keys of pArray into theKeys sort theKeys numeric repeat for each line theKey in theKeys if pArray[theKey] is an array then put _printCharXTimes(space, pDimension * 5) & theKey & cr after theText put pArray[theKey] into theTempArray put _PrintKeys(theTempArray, pDimension + 1) after theText else put _printCharXTimes(space, pDimension * 5) & theKey & ":" && "`" & pArray[theKey] & "`" & cr after theText end if end repeat return theText end _PrintKeys ``` As you can see, PrintKeys prints off every key and value in the sDataArray array. sDataArray contains the array that you, the developer, assigned to the DataGrid using a property such as dgData or dgText. PrintKeys doesn't take into account the columns you've created in your DataGrid. That is a separate property. So my guess is that you are populating the DataGrid with data that only has 10 columns.

I don't know of a way to check this from within LiveCode using existing
tools. There is an API for checking which is documented here:
https://developer.apple.com/documentation/uikit/uitraitcollection/1651063-userinterfacestyle?language=objc
It should be possible to wrap that API using LiveCode Builder. From what
I've read, I think you also need to respond to a trailCollectionDidChange
message in case the user changes the setting while your app is open:
https://developer.apple.com/documentation/uikit/uitraitenvironment/1623516-traitcollectiondidchange?language=objc
The easier (temporary) solution would be to tell the OS to use light
appearance for your app. It looks like there is an Info.plist key that you
can add which will force your app to use the light appearance. Perhaps that
will help in your situation?

Adding `the caller` to LiveCode Script
About 15 years ago Dar Scott added a feature request to have a function that returns the long ID of the caller's caller's object: https://quality.livecode.com/show_bug.cgi?id=1954 Two years ago LiveCode Builder added `the caller` which does just that, but only in LCB. If anyone is looking for a contribution to make to the engine I am throwing this out there as something to consider: Add `the caller` to LCS. Why is this useful? When writing handlers that send callback messages it is sometimes desirable to send the message to the object that called the handler. For example, let's say I have a library that makes REST calls to a server API. This calls are asynchronous so a handler in the library will need to notify the caller that the request is finished. If a handler from the library was called from a card then I might want the callback to be sent to the card. If a handler was called from a group then I might want the callback to be sent to the group. The current solution is to pass the long id of the object you want the callback sent to as a parameter to the library handlers. For example: restAPIGetObjects tId, the long id of me # callback will sent to me If you aren't using password protected stacks then you can use `the executioncontexts` to get the information you need to determine the caller. But when a stack is password protected the necessary information isn't included in `the executioncontexts`. I have a recent real world example. I rewrote the REST API interface in an application I work on to use behaviors that I attach to cards in my UI stacks. The design allows me to segment REST calls made within a specific object (card or group) so that callbacks and cleanup are very simple to manage. The need to pass the long id of the caller as a parameter if I want the callback for a specific handler to be sent to a group on the card shouldn't be part of a handlers parameter list, however. -- Trevor DeVore ScreenSteps www.screensteps.com ___ 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

Apple provides API calls to do this and wrapping Objective-C APIs is pretty
straightforward. The APIs you are interested in:
Get frontmost app:
https://developer.apple.com/documentation/appkit/nsworkspace/1532097-frontmostapplication?language=objc
Get bundle identifier of frontmost app:
https://developer.apple.com/documentation/appkit/nsrunningapplication/1529140-bundleidentifier?language=objc
I have a macOS LCB "playground" repo where I test a number of things out
and upload them for others to see. Take a look at
the NSWorkspaceGetFrontmostApplication function:
https://github.com/trevordevore/lc-macos-toolset/blob/master/NSWorkspace/nsworkspace.lcb#L133
You can call it like this:
```
put NSWorkspaceGetFrontmostApplication("bundle id")
```
If I run the function from within LiveCode it returns "com.runrev.livecode".
If I run the following in the message box and switch to Chrome it returns
"com.google.Chrome":
```
wait 1 second;put NSWorkspaceGetFrontmostApplication("bundle id")
```
So I would think it would do what you want. You would, however, need to
compile the nsworkspace.lcb and load the resulting extension in your app.
Here are some quick instructions in case you want to try:
1. Download and unzip repo using "Clone or Download" link found at
https://github.com/trevordevore/lc-macos-toolset
2. Launch LC 9 and open the Extension Builder (EB) from Tools > Extension
Builder menu.
3. Click on the folder icon in top right of EB window and select the
./NSWorkspace/nsworkspace.lcb file.
4. Click on play button in bottom left of EB window.
5. Test `wait 1 second;put NSWorkspaceGetFrontmostApplication("bundle id")`
in the message box. It should return a value.
6. Look in the ./NSWorkspace folder for the module.2.lcm file. This is the
file that can be renamed, added to your application folder, and loaded
using `load extension`.
Regarding step 6 - If you don't want to store your extension externally to
your application you can also use the "+" button in the EB to install the
extension in your LC environment. Now the extension will load whenever you
launch LC and you can select "NSWorkspace" in the Standalone Builder
Inclusions tab so that the extension is bundled with your executable.

In fact, in other areas of my app I will extract parts of HTML by without relying on revXML. In this particular case I already have some LC code that parses HTML placed on the clipboard and converts it into data structure used by the application. This was originally implemented using the revXML callback feature (no tree is created in memory) and that API has worked well for the conversions I need to make. HTML may be placed on the clipboard when copying text and images from web browsers or by our good friend Microsoft Word. Microsoft Word places some very "interesting" HTML on the clipboard that needs to be massaged quite a bit before running it through revXML. There is a speed hit that occurs when running some of the regex patterns on the Word HTML that are used to strip out some markup and do things such as add quotes around attributes. Given the code that I have in place already, I would prefer to leverage HTMLTidy rather than fix every potential "gotcha" or spend time trying to optimize the code. I'm betting that HTMLTidy can do it better and faster given how mature it is. -- Trevor DeVore ScreenSteps www.screensteps.com ___ 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
Help Wrapping HTMLTidy in LCB
Hello,
While looking at solutions for converting HTML into XHTML that can be
parsed by revXML I decided to test HTMLTidy which has an option to output
the input as XHTML. While I could bundle up the tidy command line tool and
include it with my app, I prefer to wrap things up in LCB if possible.
Unfortunately I haven't gotten very far with HTMLTidy and I'm
hoping someone else might be able to figure out what I'm doing wrong. If
you are up for loading up an LCB project in LC 9 on macOS and looking at
some C files then please read on:
RESOURCES
- Github repo with LCB file, a test stack, and compiled HTMLTidy dylib for
testing on macOS: https://github.com/trevordevore/lc-htmltidy
- HTMLTidy github repo where source files are located:
https://github.com/htacg/tidy-html5
WHAT WORKS
In the htmltidy.lcb file I've wrapped some of the simple APIs that return
strings: tidyReleaseDate(), tidyLibraryVersion(), and tidyPlatform(). Those
all work.
WHAT DOESN'T WORK?
tidyHTMLToXHTML() in the htmltidy.lcb file has some test code in it that
isn't working. As a test I want to call `tidyOptGetIdForName()` from the
htmltidy C library and get a valid value returned. I expect the following
code to log `0` but it is logging `104`. I don't think I am creating
the Ctmbstr pointer properly but I don't really know. Here is code from the
htmltidy.lcb file along with links to the ctmbstr definition in the
HTMLTidy source code:
```
variable tCStr as Pointer
-- Attempting to create a Ctmbstr from a LiveCode string
-- ctmbstr:
https://github.com/htacg/tidy-html5/blob/next/include/tidyplatform.h#L607
MCStringConvertToCString("TidyUnknownOption", tCStr)
-- The next handler is logging `104` which is N_TIDY_OPTIONS (error)
-- Appears that tCStr is not the right format.
log c_tidyOptGetIdForName(tCStr)
```
MCStringConvertToCString is defined as follows in the htmltidy.lcb file:
```
foreign handler MCStringConvertToCString(in pString as String, out rCString
as Pointer) returns CBool binds to ""
```
If anyone can provide some pointers or a PR I would really appreciate it.

Effective rect of stacks on Windows 10
I am looking for input from people who are using `the effective rect of stack` and the values it reports on Windows. I have some code that uses the effective rect of a group to determine if the stack is still on the screen after the user moves the stack or when restoring window positions when an app relaunches. On Windows 10 I just noticed that `the effective rect of stack` includes the drop shadow that appears along the left, bottom, and right of a window on Windows 10. For my use case including the shadows in the `effective rect of stack` serves no value. I'm wondering if someone has a use case where it is helpful to have the drop shadow included in `the effective rect`? Here is how you can check behavior if you are interested: EXPECTED RESULT: The effective rect of a stack on Windows would return the rect of the stack that includes stack borders and title bar. OBSERVED RESULT: The effective rect includes the drop shadow of the window in the rect. RECIPE: 1. Create a new stack 2. Set the topleft of the stack to 0,0 3. `put the effective rect of this stack`. The left of the rect will be a negative value. 4. `set the effective topleft of this stack to 0,0`. The left of the stack will be offset by the negative value from (3). -- Trevor DeVore ScreenSteps www.screensteps.com ___ 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

macOS Notarization helper for Levure
Hi all, After reading the article by Matthias on notarization* I put together a helper for Levure that will notarize a DMG image when you package your Levure application. Here is the link: https://github.com/trevordevore/levurehelper-macos_notary To use it you will need to update to version 0.9.2 of Levure which I released today. Here are the release notes: https://github.com/trevordevore/levure/releases/tag/v0.9.2.0 If you need help creating a DMG of your app then the dropDMG helper can take care of that if you have dropDMG: https://github.com/trevordevore/levurehelper-dropDMG Of course, someone could write a helper that uses Apple's command line tools to create a DMG as well. * http://lessons.livecode.com/m/4071/l/1122100-codesigning-and-notarizing-your-lc-standalone-for-distribution-outside-the-mac-appstore -- Trevor DeVore ScreenSteps www.screensteps.com ___ 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

The last update I received was what others heard at the LiveCode Conference. My thoughts are based on what I think I would do if I was in their place. While I make my business decisions based on what LiveCode can do now (a wise senior engineer once counseled me not to base my business on what other companies *might* do), I am very interested in the company's health as the LiveCode platform affects my ability to deliver great software using LiveCode in the future. LiveCode is a very ambitious project. The number of platforms they are trying to support requires an enormous amount of planning, programming, and other resources to create, maintain, and improve. I am heavily invested in LiveCode as a platform so I want very much for the company to have healthy revenue streams. Based on what I've heard, the LiveCode FM product addresses a very important problem that companies are willing to pay recurring licensing fees to overcome. It is a wonderful thing when a company can find a large pool of customers that have a problem they are willing pay to them you to solve. So while I'm less enthusiastic about development on LiveCode slowing down right now, I support the company pursuing this opportunity. -- Trevor DeVore ScreenSteps www.screensteps.com ___ 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

Perhaps they are trying to quickly fill in the gaps based on that interest so that they can close more licensing deals?

DataView Paginated Scroll
Howdy folks, I've uploaded a new behavior built on top of the DataView which facilities progressively loading paginated API data as you scroll. I needed this for an application and I've tried to abstract it and document it so that it might be useful to others. It is called DataView Paginated Scroll. For those who use APIs that return "pages" of results (e.g. records 1-20 of 760 records) this extension of the DataView control greatly simplifies knowing when to ask the server for more records. For example, if the user scrolls to the end of the DataView you don't need all of the results in between the beginning and end. You just need the last page. The DataView is intelligent in that regard and only requests the lats page of results to display. I've updated the DataView Demo project on GitHub with a Pokemon tab that uses an publicly available API that lists Pokemon. You can find the demo repo here: https://github.com/trevordevore/dataview_demo/tree/master The actual DataView Paginated Scroll helper repo is here: https://github.com/trevordevore/levurehelper-dataview_paginated_scroll -- Trevor DeVore ScreenSteps www.screensteps.com ___ 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

This works with links in a browser so that a web page can contain a link that launchers your application. I don't know if it will work from a PDF file, though. It may depend on the PDF viewer or other variables. It is probably worth trying as you can embed the "page" number in the url. On Windows you need to update the Windows Registry. Here is a link to some code in a library that ships with Levure that will set the appropriate values in the registry: https://github.com/trevordevore/levure/blob/develop/framework/helpers/file_system/file_system.livecodescript#L193 You can run this code when your application first launches. On Mac/iOS you need to add some keys to your Info.plist file. The README for the library has an example: https://github.com/trevordevore/levure/tree/develop/framework/helpers/file_system#url-protocols Once you've set the registry/Info.plist files up (you will need to launch the app at least once on macOS so it picks up the settings in the plist file) your app will be launched when the URL protocol is triggered. On macOS you will handle an appleEvent. You can look at the code in the library for hints: https://github.com/trevordevore/levure/blob/develop/framework/helpers/file_system/file_system.livecodescript#L83 For Windows you can read the `commandArguments` when the app launches or, if the application is already running, handle the `relaunch` command and use the parameters passed to it.

Re: Stop Integer Coercion to Scientific Notation in JSON

While ArrayToJSON does fix the problem you are experiencing, it does
introduce additional problems. Try the following code:
```
on mouseUp
put 1 is 1 into tValueA["root"]["boolean_1"]
put 1 is 0 into tValueA["root"]["boolean_2"]
put null into tValueA["root"]["null_1"]
put "100" into tValueA["root"]["text"]
put 100+0 into tValueA["root"]["number"]
put ArrayToJSON(tValueA)
end mouseUp
```
The output is as follows:
```
{
"root": {
"boolean_2": false,
"text": 100,
"null_1": "",
"boolean_1": true,
"number": 100
}
}
```
ArrayToJSON won't ever quote numbers, even if the variable in LiveCode has
the number stored as a string (and not an integer or a real). Imagine a
user enters the string "100" into a text field and then your app sends that
value to a JSON API. If you send an integer to a JSON API that is expecting
a string you will most likely get an error.
The output would more appropriately be rendered this way:
```
{
"root": {
"boolean_2": false,
"text": "100",
"null_1": null,
"boolean_1": true,
"number": 100
}
}
```
Here is a variation on ArrayToJSON that renders the more appropriate output:
```
function ArrayToJSON pArray,pForceRootType,pPretty
local tKey, e
repeat for each key tKey in pArray
if pArray[tKey] is an array then
put "}"(pArray[tKey]) into pArray[tKey]
else if pArray[tKey] is NULL then
put "null" into pArray[tKey]
else if pArray[tKey] is strictly a boolean \
or pArray[tKey] is strictly an integer \
or pArray[tKey] is strictly a real then
put pArray[tKey] into pArray[tKey]
else
# treat as a string
put "}}"[tKey] into pArray[tKey]
end if
end repeat
return(mergJSONEncode("pArray",pForceRootType,pPretty))
end ArrayToJSON
```
In my projects I use this modified version of ArrayToJSON to export JSON
and a wrapper around JsonImport to import JSON. In my experience that gets
me the closest to expected values. Unfortunately JsonImport is rather slow,
but it is more accurate. I don't recall all of the nuances as to why though.
Here is my wrapper around JsonImmport:
```
function _importJSON pJSON
# zero width joiner breaks JSON Importer
# http://quality.livecode.com/show_bug.cgi?id=19691
replace numtoCodePoint("0x200D") with empty in pJSON
return JsonImport(pJSON)
end _importJSON
```
