You can use a stack with a field in it for converting to htmlText, or 
run the html through the templateField.

Re: HTML entity escaping?

[David Bovill via use-livecode]

Hi Devin, yes that would work for an app - but this is for Livecode server
- I'm not sure but is there a way to do that with revIgniter - ie create a
field by script and use the functionality that way - this is the old hack
I'm using / found - if anyone finds it useful / can improve on it ( i
should probably use arrays):

Re: Get RGB color of a specific screen location

[hh via use-livecode]

Looking again at your problem my experiences with both statistics
and images say that the *median* would be a better average than
the *arithmeticMean*. So you could try and compare both averages
(more exactly: location parameters of your WxH-color-distribution).

local t="temp"

-- hL,vL is the topleft of the pixel-rect on your screen
-- the width  of the pixel-rect is w. W is an integer >= 1.
-- the height of the pixel-rect is h. H is an integer >= 1.
-- tp is the average method "median" or (default:) "arithmeticMean"
-- average is taken from the pixel-colors of rect (hL,vL,hL+w,vL+h)
--
function averageColor w,h,hL,vL,tp
   export snapshot from rect (hL,vL,hL+w,vL+h) to img t as PNG
   put the imagedata of img t into iData
   put the alphadata of img t into aData
   repeat with i=1 to w*h
  put byteToNum(byte 4*i-2 of iData) into redA[i]
  put byteToNum(byte 4*i-1 of iData) into greenA[i]
  put byteToNum(byte 4*i   of iData) into blueA[i]
  put byteToNum(byte i of aData) into alphaA[i]
   end repeat
   if tp is "median" then
  return trunc(median(redA)),trunc(median(greenA)), \
 trunc(median(blueA)),trunc(median(alphaA))
   else
  return trunc(avg(redA)),trunc(avg(greenA)), \
 trunc(avg(blueA)),trunc(avg(alphaA))
   end if
end averageColor

-- usage example:
on mouseUp
   lock screen; lock messages
   put 5 into w0; put 5 into h0
   put -w0+the left of this stack into sL 
   put -h0+the top of this stack into sT -- = without window bar
   
   if there is no img "temp" then create invisible img t
   if there is no field t then
  create fld t
  set rect of fld t to (0,0,128,23)
  set botleft of fld t to the botright of me
   end if
   if there is no grc t then
  create grc t
  set opaque of grc t to true
  set rect of grc t to (0,0,23,23)
  set botright of grc t to the botleft of me
   end if
   
   put averageColor(w0,h0,sL,sT,"median") into x --> returns r,g,b,alpha
    use x, for example:
   set backColor of grc t to item 1 to 3 of x
   --set blendlevel of grc t to round(100*(1-(item 4 of x)/255)) -- if wanted
   put x into fld t
   unlock screen; unlock messages
end mouseUp

Re: Get RGB color of a specific screen location

[Beat Cornaz via use-livecode]

I have used the export snapshot and then the averaging. Works great. I had
forgotten about the export function (have been away from coding for 3
years).
I also had to implement Phil Davis' "set the screenMouseLoc to
globalLoc(tLocWithinMyStack)".
The average I got first (with only the mouseLoc) was offsetted to where I
clicked. Now it purs :-)

Thanks again, Beat

It is in fact an interesting question how much of the IDE can be "ported"
to a HTML5 standalone. Currently we are at the level of a non-debugging
message box. If somebody is willing to dive deeper into this -- I have
currently too many other projects...

> And also has code folding...

That's done by the codeMirror editor. All I had to do for that editor was
to write the setup, implement the communication with the standalone and
roughly define a language file "livecodescript".

And code folding is not at the high level of *bn's code folding* in the
IDE's script editor ;-)

Re: TestInStandalone v_100

[Niggemann, Bernd via use-livecode]

Hello Hermann,

this is a super HTML5 stack. It lets one easily test what works and does not 
work in HTML5 stacks.
Anyone interested in HTML5 stacks should at least have a look at it.

At times it is hard to believe that it is "just" a HTML5 stack, it seems like a 
little IDE in its own.

And also has code folding...

Thank you

Bernd

Checking xml string

[jbv via use-livecode]

Hi list,
Does anyone has a function that would remove "ghost tags" from
an xml string, for instance a  tag when there's no 
tag before ? More generally, a script that checks the consistency
of an xml string and points errors would do perhaps ?
Thanks in advance.
jbv

Re: windows defender issues? & other AV issues?

[Matthias Rebbe via use-livecode]

The whole discussion made me remembering that on my Mac i noticed a really 
significant performance loss in SE when outputting large data in message box.
When this is happening i can hear my fans boosting and the cpu temperature is 
increasing.

As soon as i close the message box or empty it the SE is responsive again,the 
temperature is lowering and the fans go into normal mode.

This script for example
repeat 2
put "12asdfadsfasdfasdfasfasdf3453"  after tOut
end repeat
put tout

is able to force this behaviour on an iMac 4Ghz i7 with 32GB ram.

Just test with LC9.0.2
