Re: using the map widget

[William Prothero via use-livecode]

Herman made an excellent stack that demos the use of Google Maps. I have a link 
to it here:
http://earthlearningsolutions.org/google-static-maps-demo/ 

You need to get an API key from Google, but the demo shows how to set it up. 
This may  be more useful than the widget, as there is a lot of documentation by 
Google on how to set it up, which is pretty easy.
Best,
Bill

Thanks, Brian. I didn’t think of that previously, but I now find that it

Re: How to find the offset of the last instance of a repeating character in a string?

If that is all you are after then I think setting the itemDelimiter to
"/" and separating the 'item -1' (page) from 'items 1 to -2' (path)
would give you a very simple a readable solution.  The only problem is
if you have the unlikely but not impossible situation where you have
paths that contain no pages.  Because of the known gotcha with LC and
how it counts items when the last item is empty you may need to
include and 'if' statement.

Try this, create a new Stack with a field and a button.

Into the field load the following text:

https://www.my.org/assets/general/february/
https://www.my.org/assets/general/march/
https://www.my.org/assets/general/april/2018.zip
https://www.my.org/assets/general/may/2018.zip
https://www.my.org/assets/general/june/2018.zip
https://www.my.org/assets/general/july/2018.zip
https://www.my.org/assets/general/july/2017.html
https://www.my.org/assets/general/july/2016.text
https://www.my.org/assets/general/july/2015.jpg
https://www.my.org/assets/general/august/2018.zip
https://www.my.org/assets/general/september/2018.zip
https://www.my.org/assets/general/october/2018.zip
https://www.my.org/assets/general/november/
https://www.my.org/assets/general/december/

Into the button load the following script (be careful of line breaks
there are 16 lines of code):

on mouseUp
   put fld 1 into tText
   set the itemDelimiter to "/"
   repeat for each line tLine in tText
  if (char -1 of tLine = "/") then --usual problem with dealing
with empty last items
 put empty into tPath[tLine]
  else
 if (tPath[item 1 to -2 of tLine] = empty) then  --initial entry
put item -1 of tLine into tPath[item 1 to -2 of tLine]
 else  --multiple entries
put tPath[item 1 to -2 of tLine] & cr & item -1 of tLine
into tPath[item 1 to -2 of tLine]
 end if
  end if
   end repeat
   breakpoint
end mouseUp

There is breakpoint at the end so the script will pause and you can
inspect the variables.  You'll see that an array is created with each
unique path as a key and each page its element.  In the case of 'july'
you will see that four pages are all listed, one per line.

From there it should open a world of possibilities to arrange, sort
and sift through the paths.

Continual iOS Simulator Problems

Hi Folks,

I’m on a Mac with OS 10.14 and using LC 9.0.0 Indy, and I have the green square 
indication in LC prefs with SDK 11.2. 

I can’t get the simulator to work with test target set to simulator 11.2. It 
simply takes too long to open and then crashes if I persist.

In fact, it seems to me that I’ve had this problem with the simulator not 
working in previous versions as well.

Any help or suggestions are greatly appreciated.

api code in the inclusions and have looked at the example given in the
livecode article but so far it has not worked.  Does anyone have an example
of using it in an app?  What I want is to be able to retrieve the current
location (lat and long) and then use that to present

my map in the map widget.  I would have hoped it would be fairly straight
forward but I have never actually seen an example of script that works..  I
would appreciate any help anyone might have.

Re: Hmmm - no compilation error ?

[Monte Goulding via use-livecode]

The parser is often lenient at the end of statements like this. 

In the case of the return statement it first looks for the expression to return 
then checks if the next token is either `for` or `with`. If it isn’t either of 
those it doesn’t look any further or throw an error.

Really we should have a general check for extra stuff after parsing statements 
but we don’t. Stuff like that can also be a bit risky to add as all of a sudden 
a lot of scripts that work perfectly well might not compile.

Cheers

Monte

Hmmm - no compilation error ?

[Alex Tweedly via use-livecode]

I accidentally typed the equivalent of

function x p
   return return p
end x

i.e. I had the word "return" in there twice.

And it didn't give me an error on compilation, and also didn't just 
ignore the repeated word, it simply returned a blank line.


Does it seem like this is a bug ?  Is the parser too lenient ?

(LC 9.0.0, and 8.1.5 tested)


O - and while testing it out for this email, I tried to type

ask "a" & x(3) & "b"

but instead I did

ask "a"  x(3) & "b"
(i.e. missing an '&')

and that too didn't give an error; it simply ignored the extra part of 
the line. !?


Thanks

Alex.

That will only give him the item, not the character position. But it's a start. 
You can now get the number of characters of item 1 to -2 of pText +1. I didn't 
know the text you were searching had regular delimiters, and you were searching 
for the last delimiter. That makes things *much* easier.

Re: Is it not possible to write to the user preference folder in Mojave?

[Bob Sneidar via use-livecode]

Sounds like more onerous sandboxing. I see why it's necessary, but I have a 
simpler and more elegant solution: Have an international moratorium on all 
malicious hackers where the penalty is a life sentence on the frozen moon Rura 
Penthe. By that I mean hard labor. Until we get tough, and I mean really REALLY 
tough on offenders, and leave them with no place to hide, what we get in the 
end is devices we ourselves are locked out of, and then hackers seem to be able 
to get in anyway. 

Makes me crazy. So much for the golden age of the Internet, where compassion 
and tolerance flows from our mutually gained respect and understanding for all 
cultures and peoples. I like to say that the Internet is less like an 
Information Superhighway, and more like the wild, wild west with bands of 
highwaymen poised to waylay the unarmed and unsuspecting traveler. If I taught 
a computer class, that would be the first thing I would press home about shared 
computing.

Re: How to find the offset of the last instance of a repeating character in a string?

[Bob Sneidar via use-livecode]

In dBase/Foxpro they had an AT function synonymous (roughly) with our offset 
function. They also had a RAT (Reverse AT) function. I needed something like 
this many moons ago. 

What I did to get all occurrences is I have a "pointer" variable I maintain 
with the position of the first character after the last instance of the string 
found. But to get the actual position in the original text, you have to add the 
pointer to the offset like so:

put 0 into tPointer
repeat
put offset(tVar, tTextChunk, tPointer) into tNextPos
if tNextPos = 0 then exit repeat
add tPointer to tNextPos
put char tNextPos to tNextPos + length(tVar) of tTextChunk into 
aFoundChunks [tNextPos] [length(tVar)]
put tNextPos + length(tVar) +1 into tPointer
end repeat

Something along those lines. Not tested, but you get the idea.

Re: Mysteries of Me

[Bob Sneidar via use-livecode]

Me always refers to the object the script belongs to. It doesn't matter which 
handler it is. A script running in a behavior is like running an instance of 
the target object (the object with the behavior set). This allows for multiple 
objects with the same behavior (think datagrids calling get the dgData in other 
dataGrids and you will immediately see why this would be necessary). This me 
refers to the actual behavior object, NOT the "instance object" as it were. 

As far as a backscript, are you saying you have a backscript object with a 
behavior assigned to it??

There was a discussion on this topic on the list a few years ago, and I saved 
these functions in my script library:

From Peter Brigham:
These are utility functions I use constantly for text processing. 
Offsets(str,cntr) returns a comma-delimited list of all the offsets of str in 
ctnr. Lineoffsets(str,cntr) does the same with lineoffsets. Then you can 
interate over the list of offsets to do whatever you want to each instance of 
str in cntr. I keep them in a utility stack that is in the stackinuse, so it is 
available to all stacks. I don't use regex, as I have never gotten the regex 
syntax to stick in my head firmly enough to find it natural, and in any case 
doing it by script turns out to be as fast or faster.

Peter's lineOffsets function returns a line number for each found char offset. 
I added a function that returns only unique line numbers.

function offsets str,cntr
-- returns a comma-delimited list of
-- all the offsets of str in cntr
put "" into oList
put 0 into startPoint
repeat
put offset(str,cntr,startPoint) into os
if os = 0 then exit repeat
add os to startPoint
put startPoint & "," after oList
end repeat
if oList = "" then return "0"
return item 1 to -1 of oList
end offsets

function lineOffsetsAll str,cntr
-- returns a comma-delimited list of
-- all the lineoffsets of str in cntr
# (returns a line number for ALL instances)
put offsets(str,cntr) into charList
if charList = "0" then return "0"
put the number of items of charList into nbr
put "" into oList
repeat for each item n in charList
put the number of lines of (char 1 to n of cntr) \
& "," after oList
end repeat
return item 1 to -1 of oList
end lineOffsetsAll

# added by Devin Asay
function lineOffsets pStr,pSearchTxt
# (returns only unique line numbers)
put empty into tList
put 0 into tStartLine
repeat 
put lineOffset(pStr,pSearchTxt,tStartLine) into tLineNum
if tLineNum = 0 then exit repeat
add tLineNum to tStartLine
put tStartLine & "," after tList
end repeat
if tList is empty then return "0"
return item 1 to -1 of tList
end lineOffsets

Hope this helps.

How to find the offset of the last instance of a repeating character in a string?

[Keith Clarke via use-livecode]

Folks,
Is there a simple way to find the offset of a character from the ‘right’ end of 
a string, rather than the beginning - or alternatively get a list of all 
occurrences?

I’m trying to separate paths & pages from a list of URLs and so looking to 
identify the position of the last ‘/‘ character.

Thanks & regards,
Keith

Mysteries of Me

[Sannyasin Brahmanathaswami via use-livecode]

I thought I had a grip on "me"

But in a script that is assigned to a stack, one assumes that "me"
refers to stack itself.
But the auto-suggestion on the SE popup menu generates an error on the
following line:
*
on openstack
   put url ("binfile:" & path_Modules()& "listen/collection.json") into
tContainer
   put JSONToArray(tContainer) into sCollectionA   
   
   # must have net connection, otherwise take to My Audio
   if not connectivity_PingServer() then
  dialog_CustomMsg "No internet connection? Going to off-line library."
  [ERROR:}go card [on tab on auto-suggestion] "listen-my-audio" of me
   end if
end openstack

# I have to use:
*
**on openstack
   put url ("binfile:" & path_Modules()& "listen/collection.json") into
tContainer
   put JSONToArray(tContainer) into sCollectionA   
   
   # must have net connection, otherwise take to My Audio
   if not **connectivity_PingServer()** then
  dialog_CustomMsg "No internet connection? Going to off-line library."
  go to card "listen-my-audio" of this stack
   end if
end openstack

#Then the SE will compile the script*
# Why is "me" generating an error?
# It should not be a suggestion if it is.

Dictionary says:

*"The *me* keyword is a reference to the object whosescript contains the
current handler. If *me* is executed in behavior script, then *me*
refers to the object that is executing the behavior script."

on openStack ... "me" ... one would think, refer to cards in the stack?

Could it be that the function

 **connectivity_PingServer()

is called from a back script -- which has no binary "cards" such**

That’s fair enough. Rotating a phone so the bottom of the portrait phone is now

right middle too, for the benefit of left-handed people.

Re: Is it not possible to write to the user preference folder in Mojave?

[Paul Dupuis via use-livecode]

We make and sell a couple of research applications developed in
LiveCode. Increasingly, on both OSX and Windows, we are running into to
customers who's permissions prevent out app from writing to locations
that were once (in older OS versions) writable. In some cases, this has
been due to changes the OS manufacturer (Microsoft, Apple) have made and
in more cases,, institutions, business, universities, etc. are locking
down computers on their networks even more than in the past. In the
cases of increased institutional lock down, local IT staff have often
been able to adjust the permissions. Increasingly (as with the next
release of our main app) we have moved to creating a folder in
specialFolderPath("Documents") for our company and placing all app files
in their as it is the one of the only fully cross platform places to be
both read and writable.

Should that be "far left center" or "far-left or right center" ?
Are people consistent enough about rotating 90'  anti-clockwise, or do 
they (like me) sometimes rotate the other way ?

Re: how to properly use the fullscreenmode and screen scaling

[Colin Holgate via use-livecode]

No comment about the main code you showed, but what you said about showAll 
isn’t quite right. All of the card will always be visible. On devices wider 
than the horizontal ratio of the card, extra content will be revealed from off 
of the left and right of the card, the height of the card will fill the height 
of the device screen. On devices that are a narrower ratio than the horizontal 
ratio of the card, extra content is revealed from off of the top and bottom of 
the card, the width of the card will fill the width of the device screen. No 
combination should ever crop into the card area.

The easiest way to use showAll is to have all of the important things within 
the card window, then have enough extra stuff off all edges. Until recently I 
would make the card window be 16:9, and have enough content above and below the 
card to cope with iPad. That approach worked well for all devices from iPhone 5 
to iPad (16:9 to 4:3, using landscape as an example). With the super wide 
recent Samsung phones (and Pixel 3 too), and the even wider iPhone X, the ratio 
gets as high as 19.5:9.

Now my approach is to have a 16:9 card, extra content up to 4:3 as before, but 
now extra content off the left and right to reach a ratio of 20:9. My typical 
16:9 size is 1024x576, and 20:9 gives a familiar looking 1280x576.

So, card window of 1024x576 and all important objects within that space, extra 
background above and below the card, to give 1024x768, and extra content off 
the left and right to give 1280x576. You could of course have backgrounds that 
are 1280x768, that would do no harm. The parts in the corners will never be 
seen.

On top of all that you may well want to place some things using code, but 
remember that the later Android phones, and the iPhone X, have a notch, so 
don’t place things at the far left center of a landscape app.

Re: Numbering lines

[Alex Tweedly via use-livecode]

Yeah, I said something that was wrong - and I did apologize and will 
happily do so again. And I managed to get "two people with one stone" 
and mis-describe both your and Geoff's valuable inputs.


So I apologize again to both of you, and anyone else I inadvertently 
knocked on the way past.


But, as you say, the important thing is that David got a couple of good 
answers, and anyone searching this thread in a few years time will see 
the answer, and not the human frailty of communication :-)

Alex,

you and JLG are important LiveCoders. What you say has double weight.
 From that alone you should double check what you claim to be true.

Wrong assertions are no argument against a method but speed is one,
of course.

Anyway, it is fine that David G. has now a fast way to do his work.

Re: Numbering lines

[David V Glasgow via use-livecode]

Thanks to everyone who helped me on this.  Apologies if I misdirected the 
discussion, but even that was very instructive.

My mouth hung open when I saw the cost of updating the progress bar every time 
through a loop.  

I guess I have become sloppy about time saving because most operations seem 
‘quick enough’ to me …and also it seems counterintuitive that adding a 
conditional line inside the loop would speed things up.  Useful information on 
arrays too.

Cheers,

David G

The first two sentences are a praise, in every culture.

The third sentence is a simple advice, no "lecture".
If it is an insult for you (or Alex) then I deeply apologize.

Although I don't understand what's "insulting" with that.
It can't be the fact that I gave that advice: What's objectively
wrong that's wrong, no matter who said it.

You don't really want that ...
