Re: Japanese (unicode?) text problem

[Tore Nilsen]

Internally LiveCode uses UTF-16. You can try to decode your text from UTF-8 
like this:


put url tUrl into tTextToDecode
put textDecode(tTextToDecode,”UTF-8") into field “indices"

Re: Japanese (unicode?) text problem

[Tim Selander]

Hi Nicolas,

Finally something I can answer!

I have found that you need to use 'open file' because that let's you 
specify the file's encoding.


Assume the path to your file is in tFile, these lines should work:

  open file tFile for utf8  read
  read from file tFile until end
  put it into fld "indices"
  close file tFile

If there is a more elegant way, I'm sure the pros will chime in!

Malte Brill stack

[Alejandro Tejada]

Hi All,

Many years ago, Malte Brill posted
a stack (or script) that shows how
to use images within text fields to
simulate a game display board.

In his sample text field, you could
type a word and automatically, each
letter was converted to a bitmap image
of the letter typed.

Probably, Malte created this stack
for one of his games, but I have lose
the reference of the message date and
stack's name.

Does anyone keeps a copy of this stack
or could find the date of publishing,
among your backups?

Many Thanks in advance!

Alejandro

Japanese (unicode?) text problem

[Nicolas Cueto]

​With Notepad++​, created a new file, pasted English and Japanese text, set
encoding to UTF-8,  then saved as .txt. (Confirmed the file by opening with
Windows' "Notepad".)

Next, in LC8.1 ran this button script:

on mouseUp
   put empty into field "indices"
   set the itemdel to quote
   put item 2 of the long name of this stack into tDataPath
   set the itemdel to "/"
   delete the last item of tDataPath
   put "/Data/bilingual.txt" after tDataPath
   put "file:" & tDataPath  into tURL
   put url tURL into field "indices"
end mouseUp

The text appears in the field, but with Japanese text garbled.

What am I doing wrong?

Thanks.

Richard,

Does this bug report match what you’re seeing?

http://quality.livecode.com/show_bug.cgi?id=18292

It’s been confirmed, but I think if you could add your comments to the bug 
report it could help the engineering team pin it down and fix it.

Regards,

Devin

Re: Fast way to retrieve a range of data

This should be pretty fast if I understand your criteria well enough..

put field "yourfield" into tData
filter lines of tData with ("2" & tab & 54 & tab & "*")

Re: Fast Algorithm to Determine Average Brightness of an Image

[Sannyasin Brahmanathaswami]

@ HH

OK I will "bite" on your idea.  but I have never examined or processed the 
imagedata. Please scrutinize my code below.  But there is a major caveat with 
your original code (see below)

I think I got it correct. 

but there is a huge difference on the result between the 1 X 1 and the 12 X 9

I have a late afternoon shot of the sun setting over the ocean. your original 
function returns

148.981481 # which seems too low…

But if I did this correctly (I may not have)

I get 

192.33  # which seems a lot more correct visually because this is bright 
image.

average across 12x 9 = 108 px = 432 bytes of image data.

did I do something wrong here. (disclaimer… this could probably be 
optimized…but still very fast)


function avgBrightness theImage
   --lock screen; lock messages
   
   if there is no img ii then create img ii
   set resizeQuality of img ii to "best"
   
   put the width of img 1 into tOrigWidth
   put the height of img 1 into tOrigHeight
   
   set width of img ii to tOrigWidth
   set height of img ii to tOrigHeight
   
   set imagedata of img ii to the imagedata of img theImage
   
   put 12 into tNewWidth
   
   # Scale down proportinally
   set the width of img ii to tNewWidth
   put  round ( (tOrigHeight*tNewWidth)/tOrigWidth) into tNewHeight
   set height of img ii to tNewHeight
   
   --set width of img ii to 1
   --set height of img ii to 1
   
   put the imagedata of img ii into iData
   
   put tNewWidth * tNewHeight * 4 into tNoPixelBytes
   
   delete img ii
   
   # get beyond first byte otherwise mod 4 returns bogus value

   put (byteToNum(byte 2 of iData) & "," &\
   byteToNum(byte 3 of iData) & "," &\
   byteToNum(byte 4 of iData) & ",")   into tAllPixelColorValues
   
   repeat with x = 5 to tNoPixelBytes
  if x mod 4 = 1 then next repeat # skip this one, all zeros here.
  put byteToNum(byte x of iData) &"," after tAllPixelColorValues
   end repeat

   put empty into item -1 of tAllPixelColorValues # remove last empty itm
   
  return avg (tAllPixelColorValues)
  unlock screen; unlock messages
   end avgBrightness
BR


But if you use your original code  and do not delete img ii, a different value 
is returned than if you uncomment that line.. if you delete img ii you get a 
different value.



function avgBrightness1 theImage
   --lock screen; lock messages
   
  if there is no img ii then create img ii
  set resizeQuality of img ii to "best"
  
  put the width of img 1 into tOrigWidth
  put the height of img 1 into tOrigHeight
  
  set imagedata of img ii to the imagedata of img theImage
  set width of img ii to 1
  set height of img ii to 1
 put the imagedata of img ii into iData
 --delete img ii
  return avg (byteToNum(byte 2 of iData), \
byteToNum(byte 3 of iData), \
byteToNum(byte 4 of iData))
  --unlock screen; unlock messages
end avgBrightness1

Also, what will be still fast enough, you could think about 
scaling down _proportional_ to 3x2 pixels (or 12x8 pixels)
and then applying the above weighted mean on these few pixels.

p.s. I checked: The one-pixel color is by LC built from the
arithmetic mean of the color channels, nearly as fast as an external!

Thanks Richard, that does answer my question.  Repeating for each line in

Tool palette and Inspector disappearing in LC8.1?

[Richard Burkett]

I probably have a number of bugs to file when I get some time to search the 
bugs database and do it, but has anyone else noticed that the tool palette 
disappears from time to time? I have an app I’m working on with a lot of 
substacks with their own menus, and I often work with a script open and the 
message box visible, and sometimes with the Inspector open, too. I’ve found 
that after enough time working, sometimes I can no longer open the Inspector, 
but more frequently the Tool Palette disappears and I have to click on the 
Message Box to return from the Browse mode to the LC editing cursor and then 
try to show the Tool Palette (which doesn’t always work when choosing the 
menu). It’s really annoyingly frequent. There are a lot of great things in LC 
8.1, but the editing interface isn’t exactly one of them.

Re: Fast Algorithm to Determine Average Brightness of an Image

There is still one option that uses a weighted grayLevel-mean
(I use these weights in imageJIT). This would reflect more
than simple averaging that one wants a dark/light decision.

return (0.1*byteToNum(byte 2 of iData) \
  + 0.6*byteToNum(byte 3 of iData) \
  + 0.3*byteToNum(byte 4 of iData))

Also, what will be still fast enough, you could think about

However, there *are* a couple of things that aren't working in release

this evening. What isn't working currently is that folding scripts don't
update the line numbers.

Re: ANN: new glx2 script editor now on line

[Bob Sneidar]

False alarm. I was misremembering that GLX2 had clairvoyance for variable 
names, but that was a feature of another script editor now long defunct.

Re: "lightening" a color

[Bob Sneidar]

Lots of graphic affects on Macs, but Win seems to lack some of that 
functionality. I will put something in front of the background, like a grapic 
object, then change the opacity of the graphic object. Makes selecting things 
with a mouse lasso impossible tho'

Re: Bug or Feature - Tranparent Buttons Non-Responsive

We discussed this issue before under the heading of "Grabbing Image

Transparent buttons have always responded to a click in any part of the 
rectangle. If it isn't happening in LC 8 then I'd call it a bug. I just tried 
it here though and it seemed to work okay, at least on desktop. Is it different 
on mobile?

Re: Silly Text Field Question

[Peter Reid]

Thanks Mike & Richmond.

Mike – your solution provides the behaviour I'm after but does seem to live on 
the edge of a runaway loop!  I increased the millisec delay from 1 to 5 to try 
to reduce the potential for a runaway situation:

local sHilitedelay

on openField
   if sHilitedelay is empty then put the millisec into sHilitedelay
   if the millisec - sHilitedelay > 5 then send "hiliteText" to the target in 0 
millisec
end openField

on hiliteText
  select the text of the target
  put the millisec into sHilitedelay
end hiliteText


Richmond – your solution matches the keyboard tabbing behaviour I'm after but 
not the mouse selection behaviour.


My own further idea was the following in the card script:

on openField
   -- on tabbing into a field highlight its current content:
   hiliteText
end openField

on mouseEnter
   -- on mousing into/across a field highlight its current content:
   hiliteText
end mouseEnter

on hiliteText
   put the id of the target into tID
   if there is a field id tID then
  -- select the text of field objects only:
  select the text of the target
   end if
end hiliteText

The above almost does what I want, but not quite. This method allows the user 
to use either the tab key on the keyboard or the mouse pointer to select 
another field. As the new field is selected, its current content is hilited 
ready to be replaced by any keystrokes.

Note that the user must simply move the mouse pointer into (or across) the new 
field but NOT click into it. When the user does click the mouse, it behaves 
normally and places the insertion point in the current content at the position 
of the mouse pointer at the moment of the click.

As with Mike's approach, the script for this behaviour is in the card script to 
provide the default behaviour for all fields on the card.

Re: Fast Algorithm to Determine Average Brightness of an Image

[Sannyasin Brahmanathaswami]

@ hh

That works!

fascinating. Though what is bright not bright, is, as you say, "not sharp" 

Images that return a value > 100 still seem bright enough to warrant darker 
type… 

and of course you may have e.g. very dark stone mountains (taking up 1/3 of the 
composition space at the bottom half of the image) with a very bright, blue 
clear sky… 

So "average brightness" has only so much utility in terms of choosing a color 
brightness for an overlay.

But, this is still very useful function.  Thank you!

  get url ("file:"& tFile)

...does the same as:

  open file tFile for read
  read from file until EOF
  close file tFile

It's just more convenient than using the three-line method (which can be 
very useful if you need for fine-grained control over the read, such as 
reading in chunks or from a particular offset).


Unless your files are much bigger than 100 MBs you should find loading 
them into memory well worth the effort for the time saved parsing them thee.

RE: What's everyone working on this month? (September 2016)

[Ralph DiMola]

I am migrating all my mobile apps from 6.7.x to LC 8.1.0. I am impressed with 
LC 8 so far now that I am into it heavy. No IDE crashes or lockups on Win 10 
and El Capitan so far. IDE load times are as fast if not faster than LC6. iOS 
builds are using Xcode 7.3.1. I have submitted a couple of bug reports and will 
have at least 1 more, but I have been able to work around them for now. The 
first app (with a few minor issues) is running OK on Android, iOS 9 and iOS 10. 
Now on to the next app. Been some long nights and a lot of "answer"s but I live 
for this. Lots of tea with honey...

Question: On the Mac the LC app is read-only now, what is the current procedure 
for modifying the plists?

Re: How to extract specific columns/line items from a CSV file?

[Keith Clarke]

Thanks Mike (& Craig) for confirming that iteration of some sort is the way to 
go. 

It’s interesting that the url container can be addressed directly, instead of 
loading the file - I’d not seen that before. I’m currently pulling each file 
into a regular variable, so will probably stick with that as only a few 
(existing) lines of code would be saved and the net overall effect on timing / 
resources is probably marginal if the file gets loaded behind the scenes anyway.

As the column names/numbers vary by CSV file name - which I have built-out in a 
ColumnsOfInterest field - it looks like I’ll also be safe to iterate through 
these items to build the row extraction line dynamically, too.

Great, thanks again - I have a direction of travel.
Best,
Keith..

What Mike said. The reason he said it is this:

 I made a 1,000,000 line CSV  dataset. I extracted two random columns from
it. The new 1,000,000 line dataset took 33 ticks.

Re: How to extract specific columns/line items from a CSV file?

[Mike Bonner]

If a file you can do this..

repeat for each line tline in url "file:yourfilename.csv"
 put item 1 of tLine & comma & item 3 of tline & comma & item 15 of tLine &
return after tExtracted
end repeat
delete the last char of tExtracted -- remove the extraneous return

Or you can put them into an array or whatever. It should be VERY fast.  If
the files are very large, you can instead open the file for read, read a
line, extract the data as above, and repeat till the end of the file. I
think using repeat for each with a file url loads the whole thing at once
then goes line to line, but I'm not sure of that.

Re: error building iOS standalone with LiveCode 8.1

[panagiotis merakos]

Since the crash occurs before the code signing takes place, I do not think
it is caused by the second workaround. I would suggest you upload another
archive that includes the audio files. The crash log would be helpful, as
well. If I remember correctly, on OSX the crash logs should be stored in
/Users/your_username/Library/Application Support/RunRev/Crash Logs.
One last thing to try: Does the crash occur when using a different stack
and adding the same assets in the Copy Files section?

Re: Silly Text Field Question

[Richmond]

Well, I missed something as well.

I just put this script in the cardScript:

on openCard
   set the autoTab of fld "f1" to true
   set the autoTab of fld "f2" to true
   set the autoTab of fld "f3" to true
   set the autoTab of fld "f4" to true
end openCard

and everything works . . . even if I did lose my temper several times.

1. When the user presses the tab key on the keyboard, the next field is

2. If the user uses the mouse to click into a different text field, the current

What's happening is that I can get 1. to work but every time the user

click occurred.

So far I've got the following in the card script to provide the same behaviour

on openField
  hiliteText
end openField

on hiliteText
  put the id of the target into tID
  if there is a field id tID then
select the text of the target

end hiliteText

Any suggestions please?

How to extract specific columns/line items from a CSV file?

[Keith Clarke]

Hi folks,
I’ve a large number of sizeable CSV files from each of which I need to extract 
just 2 or 3 specific columns. Creating nested iterations through every item in 
every line seems somewhat inefficient - as does loading each full file into 
memory - so I feel I must be missing a trick here.

Does Livecode support any elegant way of directly manipulating or ‘querying’ 
(like SQL) delimited data, to extract numbered (or named) columns/items - such 
as 1(Id), 3(Name) & 15(Summary) - from in each line from a CSV container or 
direct from a file/URL? 
Best,

Re: Fast Algorithm to Determine Average Brightness of an Image

[hh]

You could try the following function. It is "dirty" (the definition
of 'brightness' is also unsharp!), but it is very fast.

local ii="tmp-1.414214"

-- uses the average color intensity of the pixel
-- resulting from scaling down to a 1x1 image
function avgBrightness theImage
  lock screen; lock messages
  if there is no img ii then create img ii
  set resizeQuality of img ii to "best"
  set width of img ii to the width of img 1
  set height of img ii to the height of img 1
  set imagedata of img ii to the imagedata of theImage
  set width of img ii to 1
  set height of img ii to 1
  put the imagedata of img ii into iData
  delete img ii
  return avg (byteToNum(byte 2 of iData), \
byteToNum(byte 3 of iData), \
byteToNum(byte 4 of iData))
  unlock screen; unlock messages
end avgBrightness

Re: Silly Text Field Question

[Richmond]

Maybe I'm being a bit thick, but . . .

I have a stack with four textFields and this script in the cardScript:

on tabkey
   put the id of the selected fld into FLDN
   set the selected fld FLDN to not the selected fld FLDN
end tabkey

Which means that every time I press my TAB key the selection point 
(cursor) hops along

to the next field.

What I seem quite unable to do susequently, is select the text of the 
field the cursor is within.

I know I'm missing the obvious but I just can't figure out how to get the 
following behaviour with text fields...

1. When the user presses the tab key on the keyboard, the next field is 
selected and the current content of the next field is selected (so any typing 
replaces all the content).

2. If the user uses the mouse to click into a different text field, the current 
content of the next field is selected and behaves just like 1.

What's happening is that I can get 1. to work but every time the user 
mouse-clicks into a different field, that target field gets selected but its 
content is deselected and the I-bar insertion point is placed where the mouse 
click occurred.

So far I've got the following in the card script to provide the same behaviour 
for all the fields on it:

on openField
  hiliteText
end openField

on hiliteText
  put the id of the target into tID
  if there is a field id tID then
select the text of the target
  end if
end hiliteText

Any suggestions please?

Re: error building iOS standalone with LiveCode 8.1

[Chris Sheffield]

The crash is consistent, yes, even after applying the second workaround. Like I 
said, it appears to be happening during the file copy process, before the code 
signing even takes place.

If it would be helpful, I can upload another archive to my dropbox that 
includes those audio files. I didn’t include them before because it makes 
everything so huge. But I’m happy to do that if you’d like. As an alternative, 
is there a crash report somewhere that I can look at and/or send you that might 
be helpful?

Another thought I had, as another possible work around, was to build the app 
without all those audio files, then copy them into the app bundle after it’s 
built, then re-sign the app. But I’m not having much luck doing that either… 
After the re-signing process I get errors when trying to install on a device, 
about entitlements not being valid and/or the app itself cannot be verified.

Thanks,
Chris

Re: Fast Algorithm to Determine Average Brightness of an Image

[Rick Harrison]

Hi Sannyasin,

Based on my previous experiences trying to process
images with LC pixel by pixel, I would have to say no.
LC is too slow for this kind of processing.

You would probably have to use a routine written in
some other language like Objective C, or C++, etc.

If anyone else has had a different experience with this type
of image processing in LC please chime in!

Thanks,

Rick

That did the trick on the error, however, now LC is crashing when I try to 
create a build and include all the files in the app. In addition to my images 
folder, which contains quite a few png images, I also have a folder that 
contains *a lot* of mp3 files (to be exact, 8624 of them). Somewhere during the

Fast Algorithm to Determine Average Brightness of an Image

[Sannyasin Brahmanathaswami]

Use Case:

I want to place puzzle tiles on top of an image. We take a field, put a grc 
behind it, take a snapshot, crop each word off at -1000, -1000 and then 
scramble the tiles to make a puzzle… all this works really well. So I decided 
to dress it up a bit more: we dynamically choose a color for the foreground of 
the field in RGB range of 0-135 for all three colors → This gets us dark type… 
then add 100 to all the colors and this gets us a color for the bkgnd grc which 
is the same hue, but brighter (well, that depends on your preferred brand HSV, 
HSL, HSB LAB color theory, it's not that simple… but, close enough for this 
context)  tiles look great.. color is randomized for each puzzle with the 
caveat of an occasional "ugly" (in relation to the nature photo in the 
background)  but still… cool..

OK I thought hmmm we could also use light type with dark background and I got 
this working… too much fun..

Switch sUserColorRange 
case "darkType"
set the itemdelimiter to "," # just to be safe
put randomInRange(0,135) into tRGB
put comma & randomInRange(0,135) after tRGB
put comma & randomInRange(0,135) after tRGB
set the backgroundcolor of grc "startHere" to tRGB
set the foregroundcolor of fld _Quote to tRGB
# same hue for background, but light
repeat for each item tHue in tRGB
put tHue+ (115) & comma after tTileBkgndRGB
end repeat
delete char -1 of tTileBkgndRGB
set the backgroundColor of grc quoteBkgnd to tTileBkgndRGB
break
case "lightType"
set the itemdelimiter to "," # just to be safe
put randomInRange(136,255) into tRGB
put comma & randomInRange(136,255) after tRGB
put comma & randomInRange(136,255) after tRGB
set the backgroundcolor of grc "startHere" to tRGB  ## oops need to fix this… 
too light, disappears
set the foregroundcolor of fld _Quote to tRGB
# same hue for background, but light
repeat for each item tHue in tRGB
put tHue- (115) & comma after tTileBkgndRGB
end repeat
delete char -1 of tTileBkgndRGB
set the backgroundColor of grc quoteBkgnd to tTileBkgndRGB
end Switch

The incoming nature photo that is the backdrop for the puzzle is a random 
selection. The above is predicated on a user choice/save-as-setting, but a 
preferred algorithm would be:

Determine average overall brightness of the image. If below 130 on a scale of 
1-255, then use light colored type on dark tile… if >130 then use dark type on 
light tiles

So is there a fast, efficient way to analyze a 1200 X 800 px image to get this 
average brightness value.

Re: LiveCode interface to SCORM /LIT

[William Prothero]

Martin:
It’s actually LTI here is a link:
http://www.imsglobal.org/activity/learning-tools-interoperability 


There is another protocol that is getting support in the US called “Common 
Cartridge”. Link:
https://www.imsglobal.org/cc/ccfaqs.html#37 


Common cartridge seems to have been built in response to the shortcomings of 
SCORM. SCORM is most useful for training, while Common Cartridge and LTI are 
more oriented toward higher ed, with more features necessary for assessment of 
student learning.

If an investment is to be made in developing software to interface with an LMS, 
I hope they can interface with a variety of popular platforms, like Moodle, 
Blackboard, Canvas, and others I haven’t come across.

Best,
Bill

I am interested integrating my app with an LMS but felt there were too many

Could this be another approach to integrating LiveCode and an LMS?

Todd,
There's another LMS interface gaining some use, called "Common Cartridge". It 
addresses shortcomings that SCORM has for assessment of learning and will 
probably displace SCORM in higher Ed.

Re: Silly Text Field Question

[Mike Bonner]

Try this..

local sHilitedelay

on openField

-- sHilitedelay is used to avoid a weird side effect when regaining stack
focus
-- by clicking on a field in the card.  If a field other than the
previously selected
-- is clicked, it can start a runaway loop. The delay solves this problem.
-- when experimenting you might put in a "if the shiftkey is down then exit
to top"
-- so you can break out of the loop if necessary, though the delay does
appear to solve it fine.
   if sHilitedelay is empty then put the millisec into sHilitedelay

-- use send in time so that all the housekeeping is completed before you
try to hilite
   if the millisec - sHilitedelay > 1 then send "hiliteText" to the target
in 0 millisec

end openField

on hiliteText
   select the text of the target
   put the millisec into sHilitedelay
end hiliteText

Re: Xcode 8 / iOS 10 support coming in 8.1.1

[Randy Hengst]

Panos,

Thank you for the help. I’ve finished rebuilding and submitting the updates to 
Apple.

I received the same error message with multiple apps. But, I cannot reliably 
recreate the problem. I’ll continue to pay attention to this issue as I 
continue to migrate to LC 8.x

be well,
randy

 Hi Randy,
 
 The version of Xcode you choose in [Preferences -> Mobile support] only
 decides which version of the iOS SDK will be used to *build* the iOS
 standalone app.
 
 In the Standalone Application Settings, you can choose the minimum iOS
 version you want your app to *run* in.
 
 So you set this option to "8.0 or later"
 
 Best regards,
 Panos

Re: error building iOS standalone with LiveCode 8.1

[panagiotis merakos]

Hi Chris,

I just tested with your stack in LC 8.1.1 RC-1 (not public) and I confirm I
still get the "resource fork, Finder information, or similar detritus not
allowed” error when building an iOS standalone. After further
investigation, it seems this is caused *only* if you add the "Internet" or
"tsNet" inclusion in the "Inclusions" pane. I will change the status of
http://quality.livecode.com/show_bug.cgi?id=18135 back to IN_PROGRESS.

Best,
Panos

Re: Dumb question about files on a server

Oh Jacque, you’ve been so kind to me over Zygodact and other things, and I’ve 
been so slow, that I didn’t dare ask! However, you are of course spot on. 
Thanks.

Silly Text Field Question

[Peter Reid]

I know I'm missing the obvious but I just can't figure out how to get the 
following behaviour with text fields...

1. When the user presses the tab key on the keyboard, the next field is 
selected and the current content of the next field is selected (so any typing 
replaces all the content).

2. If the user uses the mouse to click into a different text field, the current 
content of the next field is selected and behaves just like 1.

What's happening is that I can get 1. to work but every time the user 
mouse-clicks into a different field, that target field gets selected but its 
content is deselected and the I-bar insertion point is placed where the mouse 
click occurred.

So far I've got the following in the card script to provide the same behaviour 
for all the fields on it:

on openField
 hiliteText
end openField

on hiliteText
 put the id of the target into tID
 if there is a field id tID then
   select the text of the target
 end if
end hiliteText

Any suggestions please?

Peter
