Setting hidden of lines very slow

[Kaveh Bazargan via use-livecode]

I have a text field with some 3500 lines of text. I want to ensure all
lines are visible, as I have hidden some before. I use:

repeat with i = 1 the number of lines of fld 1
set the hidden of line i of fld 1 to false
end repeat

This is taking over 1 minute to complete. I have tried removing all styling
from the text so e.g. backgroundcolor is empty, etc. Same result.

Any suggestions pls?

Thank you guys. I am always embarrassed to ask here as I know the answer is

There is another tip here in this thread about

set the hidden of line 1 to -1 of field "the field" to false

As a single command, it might be better.

Yes Andre, that is the line that fixed it, in a split second :-)

But here is a follow-up: Now I want to hide all lines that have no text
style and only show lines with colored text. I use:

repeat with i = 1 to the number of lines of fld 1
if the textcolor of line i of fld "text" is not empty then
set the hidden of line i of fld "text" to false
end if
end repeat

This is taking time too. Any suggestions how to speed this up?

Kaveh,

I would work which lines should be shown and hidden inside a variable
and then replace the whole field...

Hello, André,
I hope you still remember that we met in Las Vegas. I still use HyperCard and wonder if it has become easier to port HC-stacks to LiveCode? Do you know if there are any apps for that? And if not, would it be difficult to write them?
Regards
Ingar

[Bob Sneidar via use-livecode]

I'll jump in here.

Porting/opening Hypercard stacks is a convenience. The primary issue is that Hypercard was optimized to index every text of every card in a stack to make finding information easier. New records? New cards.

Livecode? Not so much. In fact, not at all. There will be performance issues. But at least your field and button layouts will be intact, and you scripting *should* work out of the box.

At that point, your next task will be to refactor your app to switch to a database oriented app with single form layouts as opposed to multiple cards as records. Getting the information out of your cards and into a database, although not difficult, will have to be scripted. So far as I know, there is nothing that can "automagically" do that for you.

I doubt it. IIRC the format was directly dependent on QuickDraw - from
Wikipedia:

Applications using QuickDraw will still run under OS X 10.8
through macOS 10.12; however, the current versions of Xcode
and the macOS SDK do not contain the header files to compile
such programs.

https://en.wikipedia.org/wiki/Apple_QuickDraw


This is one of the benefits I've come to appreciate with open source:
data longevity. When formats and the code needed to operate on them are
free and open, data can never die.

Proprietary formats only live as long as the vendor chooses to support them.

I have a hard drive in my archives filled with data dependent on
software that no longer runs on any modern OS.

Livecode is a program for creating programs.
MacPaint is a program for creating images that as far as I know ran on 68K macs. Not sure it ever ran on PPC Macs. Not sure if MacPaint images can import into Livecode.
Asking if MacPaint works in LC doesn’t make sense to me.

I recognize the importance of asking adequate questions. I don’t know if the one about MacPaint (MP) belongs to that group. But I use MP all the time with SheepShaver and believe that the partial scriptability of MP perhaps was HC’s greatest contribution to interactive use of words and images in thinking. It’s a question of coordinating logic and imagination. Ingar

Great clarification. Thank you. Your question now makes perfect sense to me, and I don’t have the answer for you. Hopefully someone else does.

MacPaint's feature set was pretty limited, by design. It shipped with
Macs as a way to show off bitmap graphics, but simple enough that it
wouldn't compete with third-party offerings.

Is there anything in MacPaint that can't be done with LC's bitmap objects?

<<<<<<<<<<<<<<<<<<<<<<<<<<<•>>>>>>>>>>>>>>>>>>>>>>>>>>>

Hello, Devin!
As confirmed above the International HyperCard Users Group estimated there were 10,000 active HyperCard users worldwide in 2002. Is LC anywhere near that number? Maybe. And if maybe not, why not? A truly successful LC should have been able to attract the 10,000 HC users worldwide and additionally the group of dedicated LC users. Maybe 10,000 of those too? Then we are 20,000? And if not, why not? What magic was lost along the road? HC was the winner. Where is it now? My one is in my Mac, always at hand. 10,000-1=9,999. Im still here, asking for an easier access to LC. If the authoritative guide for converting HyperCard stacks to LiveCode still is Jacque’s tutorial at https://www.hyperactivesw.com/mctutorial/rrtutorialtoc.html, why not elaborate it to the tool, the app needed to make HC accessible "to the rest of us" again? Anybody takes the challenge?

Try working with the styledText property.

```
put the styledText of field "text" into tTextA

# loop through paragraphs
repeat with i = 1 to the number of elements of tTextA
# Check if first run has textcolor set
if tTextA[i]["runs"][1]["style"]["textcolor"] is not empty then
# hide paragraph
put true into tTextA[i]["style"]["hidden"]
end if
end repeat

set the styledText of fld "text" to tTextA
```

If showing *only* lines with colored text means that all others
are hidden then you could use:

...
set hidden of line i of fld "text" to \
(the textcolor of line i of fld "text" is empty)
...

Trevor's script would then read:
...
put (tTextA[i]["runs"][1]["style"]["textcolor"] is empty) \
into tTextA[i]["style"]["hidden"]
...

Here yet another fast method:

on mouseUp
put the millisecs into m1
lock screen; lock messages
put the htmltext of fld 1 into ht
set linedelimiter to "<p"
put the htmltext of fld 1 into ht
replace " hidden" with empty in ht
repeat for each line L in ht
if offset("color=",L)>0 then put "<p" & L after s
else put "<p hidden" & L after s
end repeat
set htmltext of fld 1 to s
put the millisecs-m1 into fld "timing"
end mouseUp

Did not know about textStyle which has opened a whole new world! Thank you
so much for ruining my weekend Trevor. ;-)

hh, I love the first solution, which shows the beauty of LiveCode. But the
speed is the same as before...

i will try htmltext too. A while since I worked with it.

Thanks again.

I was wondering at what stage or how the lines get chosen to be hidden or
not?

[Kaveh Bazargan via use-livecode]

I am simulating a non-contiguous selection of text with a "Find all" button
that sets the style of all found items of text.

Then I want to inspect those "selections" only but showing the paras that
contain them and hiding all other lines. So I have a full view and a
"compact" view that the user can choose by clicking a button

Kaveh,

Well, you learn something every day! I didn't know you could hide a line of text. Pretty cool!

FWIW, the fastest way that I know to remove all text stylings from a field of text is this:

put fld 1 into fld 1

In jQuery it’d be something like $j(‘div #id’).text(); selecting the field’s enclosing div by ID or class.

The equivalent of chunk expressions are ridiculously verbose in JS, but
this one's not bad:

getElementById("id").removeAttribute("style");

Hi all

I have learned a lot here, especially the hint of using styledText. But
there might be a misunderstanding. In my case, it is not necessarily the
whole line that is styled, but a line might *contain* a chunk of text that
is styled, e.g. one word in the middle of the line has textcolor set. So I
am looking to hide any line that contains no textcolor anywhere.

Trevors code contains:
...
if tTextA[i]["runs"][1]["style"]["textcolor"] is not empty then
...

If I understand correctly the ['runs'][1] is looking at the first element
of that line. I need to check that no other elements in the line are styled
either. Before I write a loop that is slow again, any quick way of checking
for a line with no style anywhere?

Thanks all for the great contributions.

K

Why do you need to simulate non-contiguous selections? Set the
listBehavior, multipleHilites, and noncontiguousHilites of the field to
true and then you can do things like:

set the hilitedLines of fld 1 to 1,3,5

But to your original question, you should use:

repeat for each line L in the htmlText of fld 1
-- put some htmlText after a variable based on what L contains
end repeat
-- set the htmlText of fld 1 to the new htmlText

Or if you know what you want to do and don't need to check the existing
textColor and hidden, just:

repeat for each line L in fld 1


Here's an example of what the htmlText looks like for a field where the
first line has a font color and the second line is hidden:

<p><font color="#00FF00">test</font></p>
<p hidden>this</p>
<p>thing</p>

So if you don't need to check the existing state your code would look
something like this:

put 0 into i -- if you need a line count
repeat for each line L in fld 1
add 1 to i -- again, if you need a line count
if <test that says you're coloring this line> then
put "<p><font color=" & quote & "#00FF00" & quote & ">" & L & "</font></p>"
& cr after newHTML
else
put "<p hidden>" & L & "</p>" & cr after newHTML
end if
end repeat
set the htmlText of fld 1 to newHTML

Apologies hh. I can confirm that the htmltext method works beautifully and
blindingly fast. I was going to try it to understand fully first. I now do
and am grateful for the amazing tricks I have learned here. :-)

So we have here two methods:
The htmlText-method and the styledText-method.

There is an interesting result in the speed comparison of the two methods.

Here the htmlText-method is significantly faster with less than at about
1500 short lines, between 1500 and 2500 short lines speed is at about the
same, for more than at about 2500 short lines the styledText-method becomes
significantly faster.

As LC flattens any nested arrays the styledText-method is probably adjustable
and worth the loop through the runs: styledText experts please come in.

## HtmlText-method for any colored text chunk in the line.
on mouseUp
put the millisecs into m1
lock screen; lock messages
set linedelimiter to "<p"
put the htmltext of fld 1 into ht
replace " hidden" with empty in ht
repeat for each line L in ht
if offset("color=",L)>0 then put "<p" & L after s
else put "<p hidden" & L after s
end repeat
set htmltext of fld 1 to s
put the millisecs-m1 into fld "timing"
end mouseUp

## StyledText-method for a whole colorized line.
put the styledText of field "text" into tTextA
# loop through paragraphs
repeat with i = 1 to the number of elements of tTextA
# Check if first run has textcolor set
put (tTextA[i]["runs"][1]["style"]["textcolor"] is empty) \
into tTextA[i]["style"]["hidden"]
end if
end repeat
set the styledText of fld "text" to tTextA```

[Tom Glod via use-livecode]

Can someone explain the seemingly extraordinary performance improvement in
using apparently its "split second" vs "over a minute"

set the hidden of line 1 to - 1 of field 1 to false

vs.

repeat with i = 1 the number of lines of fld 1
set the hidden of line i of fld 1 to false
end repeat

it doesn't seem like the loop would be the bottleneck here, but rather the
work on the field itself....but obviously, I know nothing about this engine
:D

Thanks,

Think about all the steps a computer needs to take to render text in a
field.

Multiply that by the number of lines...

So the first form populates the field only once....since its a single
command so no other states of the field will exist.

Makes perfect sense.

Right, and accessing a field is one of the most expensive operations in LC.

Maybe Richard will post his analogy to the maintenance worker again. I
found it both amusing and informative.

The code will not work if you have htmltext containing the text "color=" like:
<p>To set the color you can use color="#fa3b42"</p>

and you can also shave off some milliseconds in the styledText version by using foreach:

…
repeat for each key aKey in tTextA
      # Check if first run has textcolor set
      put (tTextA[aKey]["runs"][1]["style"]["textcolor"] is empty) \
            into tTextA[aKey]["style"]["hidden"]
 end repeat
…

For me that is always faster than your clever 'offset("color="…' version.

It is a bit strange though that the foreach always seams to be faster. If we try to sum an array with 100 000 element like:

   put 100000 into tNum
   # Create array with random numbers
   repeat with i = 1 to tNum
      put random(100) into tData[i]
   end repeat

   # Sum array by looping with index
   put the long seconds into tStart
   repeat with i = 1 to tNum
      add tData[i] to tSum
   end repeat
   put the long seconds - tStart into tTime1

   #Sum array by using foreach
   put the long seconds into tStart
   repeat for each key aKey in tData
      add tData[aKey] to tSum2
   end repeat
   put the long seconds - tStart into tTime2
   put tTime1 , tTime2, " ratio : " & tTime1 / tTime2

You will see that the second code is almost three times faster than the first one.

<Lesson>If it isn’t important that you process an indexed array in order foreach is always faster!</lesson>

Happy coding!

I know you were demonstrating the difference between "repeat for each
key" and "repeat with i=", and using 'sum' to do so (very effectively).

But for completeness, just in case someone wanted to sum an array, I
would point out that  you could also do

and that would another 4x faster again :-)

"That can't be done" wins always, because the only limit for LC is the sky
(more exactly, sadly, the sky below the 65535-limit for all coordinates).

But there's a lot of features that are not done with LC's bitmap objects.
Even in a comparison with the paint features of HC some are missing (which
of course can be done, because the limit ...).

[J. Landman Gay via use-livecode]

As far as I know, LC includes all the scripted paint commands that HC had,
and adds native color besides. The stacks I've imported that used painting
commands worked with few changes, mostly only needing to slow them down due
to LC's faster engine and more modern CPUs.

The OP wants to emulate MacPaint, so image size limitations probably won't
be an issue.

<<<<<<<<<<<<<<<<<<<<<<<<<<<•>>>>>>>>>>>>>>>>>>>>>>>>>>>



Hello, Devin!

As confirmed above the International HyperCard Users Group estimated there were 10,000 active HyperCard users worldwide in 2002. Is LC anywhere near that number? Maybe. And if maybe not, why not? A truly successful LC should have been able to attract the 10,000 HC users worldwide and additionally the group of dedicated LC users. Maybe 10,000 of those too? Then we are 20,000? And if not, why not? What magic was lost along the road? HC was the winner. Where is it now? My one is in my Mac, always at hand. 10,000-1=9,999. Im still here, asking for an easier access to LC. If the authoritative guide for converting HyperCard stacks to LiveCode still is Jacque’s tutorial at https://www.hyperactivesw.com/mctutorial/rrtutorialtoc.html, why not elaborate it to the tool, the app needed to make HC easily portable to LC and thereby accessible "to the rest of us" again? Anybody takes the challenge?

Ingar

One could make HC's interface in LC. Anyone game?

I once thought about doing it myself...

Someone on the HC list did just that many years ago using MC. I don't think
he ever finished it though, it turned out to be a lot of work and there was
little interest by then.

Did exactly that a couple of years ago . . . .

No takers at the time.

Oh yes, was rather silly of me not to keep this in mind. There is a simple remedy:

put ("color=" is in fld 1) into isInField
if isInField then replace "color=" with numToChar(5) in fld 1 preserving styles
.. do the htmltext-method ..
if isInField replace numToChar(5) with "color=" in fld 1 preserving styles

what doesn't slow down if "color=" is in only a few lines.

This may be true but the above doesn't work for the OP's question: To hide lines with
*any* textcolor property set, not only the textcolor for the whole line.

The styledText method is still very fast with the adjusted version below (make it better!).

For up to at about 2500 short lines the htmlText method is here still faster.
For more than 2500 short lines or if many text lines contain "color=" the styledText method
is faster.

The OP will simply take the version that is faster/better suited for his use case.

Here the two working methods that hide *exactly* the lines (more exactly: paragraphs)
of a field that contain no colored chunk.

-- styledText method
on mouseUp
put the millisecs into m1
lock screen; lock messages
put the styledText of field "text" into st
put st into tTextA
repeat for each key aKey in tTextA
put tTextA[aKey]["runs"] into T
repeat for each key I in T
put (T[I]["style"]["textcolor"] is empty) into tTextA[aKey]["style"]["hidden"]
end repeat
end repeat
set the styledText of fld "text" to tTextA
put the millisecs - m1 into fld "timing"
end mouseUp

-- htmlText method
on mouseUp
put the millisecs into m1
lock screen; lock messages
put ("color=" is in fld 1) into isInField
if isInField then
replace "color=" with numTochar(1) in fld 1 preserving styles
end if
put the htmltext of fld 1 into ht
set linedel to "<p"
put the htmltext of fld 1 into ht
replace " hidden" with empty in ht
repeat for each line L in ht
if offset("color=",L)>0 then
put "<p" & L after s
else put "<p hidden" & L after s
end repeat
set htmltext of fld 1 to s
if isInField then
replace numTochar(1) with "color=" in fld 1 preserving styles
end if
put the millisecs - m1 into fld "timing"
end mouseUp

[hh via use-livecode]

Sorry, the styledText method of my last post had a logic fault
(style-runs without textcolor are ignored).

The following works now for me.

-- styledText method
on mouseUp
put the millisecs into m1
lock screen; lock messages
put the styledText of field "text" into tTextA
repeat for each key aKey in tTextA
put tTextA[aKey]["runs"] into T
put true into isEmpty
repeat for each key I in T
put isEmpty and (T[I]["style"]["textcolor"] is empty) into isEmpty
end repeat
put isEmpty into tTextA[aKey]["style"]["hidden"]
end repeat
set the styledText of fld "text" to tTextA
put the millisecs - m1 into fld "timing"
end mouseUp

-- htmlText method
on mouseUp
put the millisecs into m1
lock screen; lock messages
put ("color=" is in fld 1) into isInField
if isInField then
replace "color=" with numTochar(1) in fld 1 preserving styles
end if
set linedel to "<p"
put the htmltext of fld 1 into ht
replace " hidden" with empty in ht
repeat for each line L in ht
if offset("color=",L)>0 then
put "<p" & L after s
else put "<p hidden" & L after s
end repeat
set htmltext of fld 1 to s
if isInField then
replace numTochar(1) with "color=" in fld 1 preserving styles
end if
put the millisecs - m1 into fld "timing"
end mouseUp
