Re: macOS, is my app active?

2019-11-23 Thread Ken Ray via use-livecode
Klaus,

I have a function that generally works with this AppleScript:

function stsGetFrontmostProcess
  put "tell app `System Events`" & cr & \
  "get (the name of every application process whose frontmost is true) 
as string" & cr & \
  "end tell" into tScript
  replace "`" with quote in tScript
  do tScript as AppleScript
  put the result into tResult
  replace quote with "" in tResult
  return tResult
end stsGetFrontmostProcess

Give that a try and see if it works for you.

Ken

It works here in the IDE on MacOS 10.14.6 and 10.15.1 using LC 9.5.0. or LC 
8.1.10. (I stopped using unstable LC versions a while ago).
Did you try from the IDE?

If it is from the standalone only you could also try to use osascript
via shell:

get shell("osascript " & )
or use "osascript -e " for direct input.

Works all here...

That is what I did too!

Then I went to each line and deleted the
white space until I ended up on the line
above, after that I pressed return so the
text went to its own line and it reformatted
that line properly.  This process should be
done for each line.

Did you save the stack to a before using it? If not, it has no path for the
binaries, which will be installed in folder "WIN" of your stack's folder...

If so, I can't really help as it works here.

The stack is very basic LC Script. You could start with checking whether the
binaries are written out. The rest is simply using shell() with files written
to the temporary folder.

what do you mean by "reformatting"?
I copied this from a TXT file and "pasted unformatted" into my field.

Still -> execution error

I suspect this is a permission thing, maybe I need to grant LC, and my later

permissions in the macOS Settings panel.

So the, little more complex, solution Trevor proposed suddenly looks a lot more

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
future.

Is it really worth the work to do that from LCB?

A while ago I installed HTML tidy 5.6.0 from here
http://binaries.html-tidy.org (the Mac .dmg)

Then I copied the binary "tidy" from /usr/local/bin
compressed to my stack (=231 KByte).
Now I use it from there, running it in the temporary
folder via shell(). Works fine (on any 64bit Mac).

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.

wow, lots of infos, thank you very much, but maybe a little overkill for me.

It would suffice for me to get this little snippet to work:
-
tell application "System Events"
set activeApp to name of first application process whose frontmost is 
true
return activeApp
end tell

Works fine in the AppleScript Editor, but I get "execution error" when DOing

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.

I found this snippet on the net:

tell application "System Events"
set activeApp to name of first application process whose frontmost is 
true
return activeApp
end tell

Works fine in the AppleScript Editor, but I get "execution error" when DOing 
this in LC!?
Any hints appreciated!

macOS, is my app active?

2019-11-23 Thread Klaus major-k via use-livecode
Hi friends,

can we check if our standalone is currently active, means in
the "foreground" or if it is not active? Know what I mean?
If yes, how can we do that? LC? AppleScript?

I want to alert the user if the app is active, but not if the app 
is not active.

Thanks in advance!


Best

Klaus

Re: WebP-Tool v103

2019-11-23 Thread hh via use-livecode
@BR.
There is currently not yet support for mobile (precompiled binaries).
But Android 4.0+ supports the format natively in its browser. See

https://developers.google.com/speed/webp/faq#which_web_browsers_natively_support_webp

The way you could do it on desktop (and probably as soon as supported on 
mobile):

You have only webp resources of the images (as custom props) in the stack.
The binary (could also be installed into temporary folder) converts a webp image
of the stack as soon as it is called to png (for display), on the fly.
In my stack the needed time for that procedure is displayed above the image.
After display you can delete the png -- if converting was fast enough...

@JJS.
This is most probably the reason for that:
The stack contains only the binaries for 64bit machines.
I tested successfully on a 64bit Win10 machine.

See the instructions for using the stack on 32bit machines
(this works here, I tested on a 32bit Win7 machine):

http://forums.livecode.com/viewtopic.php?p=185384#p185384

Hope this was the reason and it's fine now.
