Thanks for sharing Marty. I wonder if this is why I was having SSL issues
with the standalone I built with 9.6.2? I'll play around with the
entitlements and see if that fixes it.

Hi Bernd,

Glad you like it. I originally wrote the extension for use with the
DataView (a more modern DataGrid) which has a "row" concept rather than a
"line" concept. I hadn't applied it to fields before putting together the
test yesterday. You are correct, if should be `textHeight`, not `lineSize`,
in the script.

I came across this thread and thought I would add an additional comment.
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.

Re: clipboardData on Mobile?

2021-01-28 Thread Trevor DeVore via use-livecode
This should be possible using LCB. Years ago I posted code for an external
that copied to clipboard on iOS. I would guess that the APIs would be
straightforward to wrap in LCB for someone motivated enough to do it. Here
is the project:

https://github.com/trevordevore/iosclipboard

I don’t know about Android, but I believe there is a fair amount of Android
LCB code in the livecode GitHub repo that could used for guidance.

I've used MCStringConvertToBytes to convert strings to a value you can pass
in as const char*. I have a hunspell example you can reference.

Here is a link to the Hunspell_spell definition:

https://github.com/hunspell/hunspell/blob/8a2fdfe5a6bb1cbafc04b0c8486abcefd17ad903/src/hunspell/hunspell.h#L69

```
LIBHUNSPELL_DLL_EXPORTED int Hunspell_spell(Hunhandle* pHunspell, const
char*);
```

Here is a link to the LCB code that passes a UTF8 string to Hunspell_spell:

https://github.com/trevordevore/lc-hunspell/blob/master/hunspell.lcb#L150

Here is a link to the MCStringConvertToBytes definition in the LCB file:

You can use binary or script only stacks with Levure. It doesn’t care one
way or the other.  It’s just reading in stack files you add to your app
folder.

It is possible to convert script only stacks to binary, encrypted stacks
and save them using the same file name. 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.

Shoudl LiveCode be calling exit() when terminating a Cocoa app?

2020-08-28 Thread Trevor DeVore via use-livecode
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?

ScreenSteps uses this technique for sending actions from our web app to our
desktop. 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.

Click me

Hopefully this helps you implement the behavior in your own app.

 I don't use HTML deployment myself, but thought I would mention that there

I'm not sure how I missed that. I searched for "script only" in the

Hi Bob,

In fact script-only stacks can have behaviors. 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.

If you need to assign the behavior of the script-only stack to a button
then use method #2.

Spell Checker

2020-04-29 Thread Trevor DeVore via use-livecode
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. All of my public projects are under the MIT
license so enjoy!

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.

Testing spell checking with Hunspell Extension

2020-04-22 Thread Trevor DeVore via use-livecode
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:

Hi Andreas,

I use GutHub for my LiveCode projects but haven’t looked at other services.
I enjoy using it and they recently reduced pricing and made a team account
available for free which is great.

There aren’t any special tools for LiveCode on GitHub that I’m aware of. It
isn’t even recognized as a language by GitHub. At the moment I’m investing
how I might get automated builds working for my Levure apps using GitHub
and CircleCI. I’m in the very early stages of research and haven’t made any
real progress yet.

I love using Tower for my Git GUI. I’ve been very pleased with it.

Thanks for testing. I use `the effective styledText` in a few instances

Hi Mark,

Will this caching of the DPI setting affect accessing the styledtext
property in general on Windows or will it only affect calls to it during
saves?

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.

--
on mouseUp
 put textEncode("eins", "utf8") into tArray[textEncode("äns", "utf8")]
 put textEncode("zwei", "utf8") into tArray[textEncode("zwöi", "utf8")]
 put arraytojson(tArray)
end mouseUp
—

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.

Agreed. 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.

Paul,

I had a similar situation recently where I needed to get some DPI
information about the monitors that wasn't available through my LC main
application. I ended up writing a simple command line tool in Visual Studio
that used the Windows APIs and returned the proper information. I included
that exe with my app and called it from within LC. In your case you would
create a 64-bit command line app and I'm guessing you could find sample
code for such a common API call.

Right. But using ⌘ + Shift + 1 looks much better in the menu to me than ⌘
!. With ⌘ ! the user has to piece together that they need to add SHIFT to
create the ! character. ⌘ + Shift + 1 tells the user every key to press
just by looking at it.

Using Shift + Cmd + 1 as a menu short in LiveCode

2020-03-25 Thread Trevor DeVore via use-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. It shows the following:
File
New ⌘ 1
Open   ⌘ 0
Close   ⌘ W

Thanks for sharing that Mark. I wasn't aware that Microsoft had this
program.

My company recently announced that we are dropping official support for
Windows 7 with our next desktop update. We won't stop it from working but
we will no longer test new features on it. We haven't had anybody write
back requesting that we continue to support it. As a reference, our
customer base is made up of small to medium businesses as well as larger
corporations.

That is good to know. I convert HTML from an outside source to a styledText
array which I then assign to a field. Hopefully that isn’t affected by the
same bug since the listStyle is part of the array. I’ll make sure and test
that particular case though.

Thanks for the suggestion Bernd. 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
:-)

Nested numeric lists that include number of parent list item

2020-02-11 Thread Trevor DeVore via use-livecode
Hi all,

I am working with nested lists in LiveCode using listStyle and listDepth.
When using a "numeric" listStyle I get this output in a field:

1. asdf ajsdf asf
   1. adsfasdfasdf
  1. asdfasdfasdf

I would like to get the following output but I'm not seeing a property that
enables it. Am I missing something or is not possible using listStyle and
listDepth?

1. asdf ajsdf asf
   1.1. adsfasdfasdf
  1.1.1. asdfasdfasdf

I don't see a reason why these new complexities (at least most) can't be
hidden from most users. LC already hides all sorts of things from us that
we don't want to know anything about. Code signing and entitlements aren't
tricky problems to address, at least once you understand the problem. But
it will take time to do the research, design a UI, hook up the UI, and
write the underlying code.

[macOS] Notarization, hardened runtimes, LCB, and executables

2020-02-06 Thread Trevor DeVore via use-livecode
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).

Thanks for the kind words Håkan. I hope that repo is helpful to people who
are exploring LCB.

Folks - If you have access to Mac Status Menu in LC 9.6 (I don't know if it
is available in Community or not) I would suggest using it. That is what i
use in my applications and it works great.

BR - I'm glad you were able to locate the handler you need in the source

I'll toss in an amen to both of these points (testing optimizations, etc.
and tagging releases). I use Tower as my Git GUI with Kaleidoscope for
diffs. I can easily see a diff of all files that have changed between two
releases because I tag the commit that was current at release time of each
version.

That is correct. The SoS is opened, the the scriptonly property of the
stack is set to false, and then it is saved using the same filename. This
is all done in a temporary directory so that the source file isn't modified
at all.

Hi Richard -

One way I use Git is to develop multiple features in tandem without
affecting the version I distribute of my app that I distribute to
customers. 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.

I use SoS extensively but I had never tried using the SB to encrypt them as
I use Levure. The Levure packaging library automatically encrypts script
only stacks for you during the packaging process. While Levure uses the SB
to create the standalone, encrypting the stacks is handled in the Levure
packaging library, not the SB.

I agree that the SB should handle this for you though.

Given how PrintKeys works it would appear that the keys are being removed
from the internal sDataArray array. You can inspect the array yourself by
putting the dgData of the DataGrid into a variable and setting a
breakpoint. Or assign the dgData to a tree widget as Richard suggested.

One nice aspect of LiveCode is that you can inspect all of the code to see
what is going on behind the scenes. 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. Could that be the case?

I've added Windows support and the ability to pass boolean options so that
you can control the behavior of htmltidy when it cleanses the HTML input.
I've added some sample settings to the test stack for testing.

If anybody would like to add Linux support it should just be a matter of
following the build instructions provided by htmltidy and added the
resulting library to an `x86-linux` folder in the code folder:

https://github.com/trevordevore/lc-htmltidy/tree/master/code

You can find a link to the htmltidy build instructions in the product
README:

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

2019-11-26 Thread Trevor DeVore via use-livecode
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.

In my opinion, yes. If for no other reason then that with each library that
is wrapped in LCB I learn what the limitations are in LCB or I learn how to
do something that I didn’t know how to do before. There is a lot of code
out in the world that we could benefit from in LiveCode. Not all have as
nice a command line tool as HTMLTidy. Some don’t have a command line tool
at all. Having lots and lots of example of wrapping C, Objective-C, etc.
will help more people wrap libraries and contribute to the community in the

You’re welcome. I don’t know the solution to your problem with AppleScript.
If you do go the AppleScript route just check that you don’t trigger any
security warnings in later versions of macOS. Maybe that isn’t a big deal
for your app but it is worth checking.

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.

There are definitely other ways to approach the problem I'm trying to
solve. 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.

Help Wrapping HTMLTidy in LCB

2019-11-22 Thread Trevor DeVore via use-livecode
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

2019-10-21 Thread Trevor DeVore via use-livecode
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).

mnemonic working on Windows in LC 9?

2019-10-21 Thread Trevor DeVore via use-livecode
Does using the mnemonic key to display a menu on Windows work for anybody
else in LC 9? I just did the following test and all I hear is a beep:

1. Launch LC 9 on Windows 10.
2. Press the ALT key. The letter represented by the mnemonic setting of
each menu in the Toolbar is underlined.
3. Press the letter of one of the menus (e.g. "F"). All I hear is a beep
when the File menu should appear.

macOS Notarization helper for Levure

2019-10-09 Thread Trevor DeVore via use-livecode
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.

Hmm, looks like the docs need updating. The docs for the `processor` say it
returns the system's CPU chip which is different than how the engine was
compiled. I see there is already a Bug report for it:

Right you are. I think I'll add a "related" entry to `platform` in the docs
that points to `processor`.

2019-10-07 Thread Trevor DeVore via use-livecode
With LiveCode 9.5 one can deploy 32-bit or 64bit Windows applications.
While LiveCode Builder has an `architecture` function that can be used to
detect 64-bit, LiveCode Script does not. Does anybody have a function for
determine 64-bit vs. 32-bit architecture in LCS?

Or for those of us creating commercial applications with LiveCode. I know
the memory leak fixes in 9.0.5 improve my applications performance and
fixes crashes that customers were experiencing.

At the moment I can’t set aside time for my team to do the extra testing
required before moving development to 9.5 so I’m very grateful for 9.0.5.

Creating a great product is a wonderful journey that can go on
indefinitely given the right variables. If LiveCode FM generates lots of
revenue then it will continue on. And hopefully fuel the development of the
underlying technology (LiveCode) that LiveCode FM is built on.

Hi Lagi,

I do not have any additional information about how well the FM project or
the company is doing. 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.

I suspect that the quick updates to LiveCode FM are a sign that the launch
at the FileMaker conference generated a lot of interest and there is some
momentum building there. Perhaps they are trying to quickly fill in the
gaps based on that interest so that they can close more licensing deals? If
that is the case and they can build that revenue source then it should
ultimately be a good thing for those of us who don't use LiveCode FM. It is
unfortunate that LC has to sit mostly idle for so long though.

DataView Paginated Scroll

2019-09-20 Thread Trevor DeVore via use-livecode
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

You can define a url protocol (e.g. myapp://) which can be configured on
Mac or Windows to launch your application. 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.

Hopefully that is enough to get you started.

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

```

If you look at the headers the server is sending back the `content-encoding`

Do you know if the window opens up with the vertical displacement issue or

Thanks for pointing this out Mark. Have you filed a bug report? This is

If you don't get any pure LCS solutions you could use an extension. macOS
has an API for this:

https://developer.apple.com/documentation/appkit/nsworkspace/1529991-isfilepackageatpath?language=objc

I just tested it in my macOS test bed for extensions and it seems to work.
It is the NSWorkspaceIsFilePackageAtPath() handler in this file:

You’re welcome. One thing I forgot to mention - you need to have LC 9.0.5
or 9.5 installed to test the Pocketsphinx example. A bug was fixed related
to passing null to variadic expressions.

For those interested you can find the source code for the projects we
discussed in the LCB FFI Workshop at the San Jose Conference. The
pocketsphinx project is an experiment to get it working and teach some
concepts. The mosquitto project is an example of wrapping an API and making
it available to LiveCode. The demo stack is fully functional and you can
subscribe to and publish messages with other people if they are connected
to the same server.

I just did a quick test involving going through the property inspector for
a group and changing properties. I have confirmed that the following
properties will cause a group that is assigned the layerMode of "container"
to have an effective layerMode of  "static":

- opaque
- showBorder
- showname
- hscrollbar/vscrollbar
- dropShadow, innderShadow, outerGlow, innerGlow, and colorOverlay

In addition, the acceleratedRendering of the stack must be true or the
group will always have an effective layermode of "static".

And the way to verify that the group is actually working in "container"
mode is to check `the effective layermode` of the group. If it isn't
"container" then you have a setting that is incorrect.

My understanding is that the group must have showborder set to false and
opaque set to false.

As do I. But MSI is much easier for IT departments to roll out to all of
the computers at their organization. Or so I’m told by the people in charge
of IT over large organizations. Sometimes we have to do things that are
more work on our end to make life easier for our customers.

Question on automatically generating an MSI file

2019-05-17 Thread Trevor DeVore via use-livecode
Hi all,

I'm wondering about being able to create MSI installers for applications
built with Levure. The goal is to help IT departments easily install and
update an application using Group Policy.

I have never worked with MSI files before and know nothing about them.
Ideally a text file could be generated during the Levure application
packaging process that could be packaged up by whatever tool on Windows
creates MSI files. There are already Levure helpers that do this for Inno
Setup and DropDMG.

Does anyone on this list have a strong working knowledge of MSI and whether
or not this is feasible?

I was reading the RabbitMQ page on the MQTT plugin earlier:
https://rabbitmq.com/mqtt.html

That page says you have to manually enable the plugin in order for it to
work. Once it is enabled there is no reason Mosquitto wouldn't work with
it. They both support MQTT 3.

There is also a RabbitMQ C library that provides support for AMQP. It is
available here:

https://github.com/alanxz/rabbitmq-c

And this page seems to have some information on using it:

https://www.cloudamqp.com/docs/c.html

I haven't looked over the source code to see how easy it would be to wrap
in LCB though.

I decided to look into this further and I eventually found libMosquitto. It
is a C library with an API that that could be wrapped with FFI without too
much trouble (no structs within structs that I had to deal with). With Mark
and Monte's help I now have a library on macOS that can connect to the
test.mosquitto.org server and publish/subscribe to topics. So we should be
able to send messages around to each other during the workshop! Hopefully
there are no surprises on the Windows side...

Thanks for the suggestion Trevix. While I won't be able to spend time on
this particular library perhaps someone else will after the session!

I should also point out that Monte also provided some valuable guidance on
variable types to use with the API and working with variadic arguments.
Lots of good stuff for the workshop.

Thanks for the suggestion Paul. This ended up being a really good example
to work on.

I was hoping to just grab the precompiled DLL for it but the downloadable
version has a bug in it and would just exit whenever I tried to use it.
With Mark Waddingham's help (a lot of it) I now have a basic version
working on both macOS and Windows. Even the macOS version required some
interesting steps so that the dylibs (pocketsphinx and sphinxbase) would
only load the dylibs in the extension's code folder. Wrapping the code was
also an educational experience and has a number of teaching points that I
will bring up in the workshop.

For those of you who offered up other suggestions - I took a look at the
pages you sent but I didn't see any obvious C interfaces and they also look
like much more involved projects. FFI will not work with C++ right now.
