Re: CharToNum Depricated??

[Niggemann, Bernd via use-livecode]

Hi Bob,


Actually I think what I need to do is figure out what the original file
encoding is, and use that when I write out the export file.

I assume that the byte order mark (BOM) is for UTF-8

To see the BOM for UTF-8 make a button and a field named "fText"

Use this script for the button

-
on mouseUp
   local tPath, tContent, tBom, tCollect
   answer file "choose"
   if it is empty then exit mouseUp
   put it into tPath
   if the optionKey is down then
  put url ("binfile:" & tPath) into tContent
  delete line 2 to -1 of tContent
  put textEncode(tContent, "UTF-8") into tContent
   else
  put url ("file:" & tPath) into tContent
  delete line 2 to -1 of tContent
   end if
   put tContent into field "fText"
end mouseUp
-

and see if you see the BOM when you hold down the option key when opening the 
file
If you do not use the option key there should be no BOM at the beginning of the 
text and the text is automatically UTF-8 encoded
Apparently "put url ("file:" & tPath)" is also aware of the encoding of the 
file since it converts it omits the BOM.

Kind regards
Bernd

Re: CharToNum Depricated??

[Niggemann, Bernd via use-livecode]

Hi Bob,

charToNum has been deprecated, I think since LC 7.0

It is replaced by nativeCharToNum() and byteToNum

(As of LC 10.0.0 charToNum maps to nativeCharToNum, see release notes)

This covers the ASCII range.

For unicode you use codepointToNum()

I suspect that the small difference you see in file size is a Byte Order Mark, 
BOM at the beginning of the Konica Minolta address book.

You could try to use "open file" to import the Konica Minolta address book.

open file tFilePath for read
read from file tFilePath until EOF
put it into tData
close file tFilePath

The dictionary states

>From 7.0, it's possible to specify an encoding for the file being
opened. By doing so, you can straight read or write to a file without
having to call textEncode or textDecode; the encoding supported by
open file are the same as these text encoding functions. If no encoding
is provided, then open file tries to read a Byte Order Mark (BOM) exists
at the beginning of the file. In success, the encoding is adapted and the
BOM is ignored.


If my assumption that there is a BOM is correct then after opening and reading 
from the file should give you the same length of the data since the BOM is not 
part of the data.
I guess that is also the reason why SublimeText sees both files as identical. 
It probably also ignores the BOM.

I am just guessing and I am not an expert for these matters but maybe this 
gives you an idea to try.

Kind regard
Bernd

Export snapshot from object gives a nice image that can serve in place of the

Have you tried as "png"? It should make the black corners transparent.

export snapshot from graphic "g1" to image "iDest" as png

I tried your code on MacOS Monterey using LC 9.6.11 and LC 10.0.0 DP-7.
I saw after a short time gibberish and at times empty clipboard content. No 
crash though.
I then changed to 'fullClipboardData' instead of 'ClipboardData' and that 
worked for without a hitch for minutes.

I realise that your main concern is Windows with crashes/freezes. But maybe 
that would help on Windows too.

Re: Property Inspector bug for keys with commas in the key name

[Niggemann, Bernd via use-livecode]

Hi Paul,

I looked a bit further into the problem with commas in key names of custom 
properties.
It turns out that the widget "treeview" has the option to choose a delimiter 
for paths. Default is comma.

If you feel adventurous you could hack the properties inspector fairly easily 
to work with commas in the key names;

Recipe:

open any custom property in the PI

close the PI

Select from Menu "View": Show IDE Stacks in Lists

open Project Browser

Use the project browser to edit the script of 
com.livecode.pi.customprops.behavior

Now add to handler editorInitialize at the end

   -- more code
   set the pathDelimiter of widget 1 of me to tab -- add
end editorInitialize

Now add the line:

set the itemDelimiter to tab

to handlers:

setArrayDataOnPath
setArrayKeyOnPath
deleteArrayKeyOnPath
addArrayKeyOnPath
fetchArrayDataOnPath
keyChangedOnPath


To be sure you can do a search for "item" in the script and every handler that 
refers to "item" needs 

set the itemDelimiter to tab


Reopen the PI for a custom property containing comma in a key name and it 
should work to display key and value in PI and also lets you change the value.

If you want this change to be persistent for that particular version of LC you 
would have to save the changes to com.livecode.pi.customprops.behavior from the 
Script Editor.
Otherwise the next time you start that version of LC the changes would be gone.

I tested shortly and it worked for me. Maybe try this first on a LC version 
that is not your current working version.

I chose tab as delimiter since I doubt that tab will be used in a key name...


Kind regards
Bernd

Property Inspector bug for keys with commas in the key name

[Niggemann, Bernd via use-livecode]

Hi Paul,

The problem with the comma in a customproperty name in the Properties Inspector 
(PI) arises because the PI uses a treeview to display the customproperties. 
More specifically the "hilitedElement" to retrieve the current selection and 
"hilitedElement" has the form:
"A comma delimited list of array keys."

Now you have a comma in your customproperty name and at that point the PI is 
confused as to what is the key and what is the value and fails to display both.

However I wonder if treeview or PI is to blame:

Page 145 of "Livecode User Guide" 9.6.10
Custom Property Names
The name of a custom property must consist of a single word and may contain any 
combination of letters, digits, and underscores (_). The first character must 
be either a letter or an underscore.

Page 113 of "Revolution User Guide 2.0" printed edition from 2004
Custom Property Names
The name of a custom property must consist of a single word and may contain any 
combination of letters, digits, and underscores (_). The first character must 
be either a letter or an underscore.

So I am afraid that treeview could not expect a comma in a customproperty name.

Kind regards
Bernd

> Hey!  ... half an answer is better than none at all.


BTW the background color used for stacks while dragging a control from the 
toolbar is supposedly the "Edition Color"
While I like the blue as "Edition Color" it is a little dark as background 
color.
Just wait until LC offers the "Black Edition"...

While testing the backgroundcolor of stacks when dragging a control from the 
toolbar I was again annoyed that when stacks overlap the target stack for the 
control (usually your frontmost stack = default stack) the background color 
only changes when you leave the rect of a partially overlapping stack although 
your mouse is within the rect of your default/target stack. That in my opinion 
is not the best user interface.
Since I work on a laptop the problem of overlapping stacks is not uncommon.

I had a look at it and made an enhancement request with a proposed fix.

Anyone adventurous enough could test the proposed patch by applying it

Sorry, I did not get that you meant the highlight color of the input field of

I see that you use Window. I am on a Mac. The highlight color for all text in 
LC on a Mac is controlled by "System Preferences" -> "General". and is applied 
system wide to all apps. 
No idea how this is handled on Windows Computers.

For me the backgroundcolor of the input line of the MessageBox is controlled by 
my setting of the backgroundColor of the Script Editor in LC Preferences.
That also changes the backgroundcolor of the input field of single line and

Re: Maximum field size

[Niggemann, Bernd via use-livecode]

I tried to put text into a field on an arm MacBook Pro 32 GB memory, LC 9.6.9 
rc2 running natively. I realise that this is 64 bit.

I took a couple of lines of Lorem Ipsum and put it into a field. Then I put the 
formattedText of that field into the field to force lineFeeds at every visible 
line. 35 lines overall.

I then put that text a million times into a variable.
That variable was put into a field that was a little wider than the originating 
field to avoid line wrapping in the target field and also set the dontWrap of 
the target field to true.

The result:

35.000.000 Lines in the field
1.109.000.000 bytes, roughly 1.1 GigaBytes in the field
525.000.000 Pixel line 1 to -1 formattedHeight
160 seconds to fill field
App Memory Size went up to 17 GB, went down to 480 Mb after clearing the field.

The field could be scrolled although with a lot of Pizza spinning. After some 
fiddling with scrolling down to the end I was able to insert a return after the 
last line. (a bit of pizza)
Blinking cursor in field very slow.
LC slowed down but responded reasonably once the focus was away from the long 
field.

LC did not crash but did not really like that much text in a field.

No more than 32,786 pixels wide for display

If you put lines longer above limits then LC will hang/crash

The amount of lines a field can hold is a lot higher provided the individual 
lines are not too long.

Re: Tab groups broken?

[Niggemann, Bernd via use-livecode]

I have to correct correct myself.


https://developer.apple.com/documentation/appkit/nstabview

shows the familiar blue hilited button in the screenshot of "Date and Time" in 
Preferences.

But if you look at a recent MacOS (12.6.2 Monterey) and go to Preferences and 
look at "Date and Time" you see that the hilited button of tabbiew is not blue 
anymore.
That was what I was looking at.

Re: Tab groups broken?

[Niggemann, Bernd via use-livecode]

Hi Geoff and Mark,

The tab group seems to be in line with Apple's current Human Interface 
Guidelines (HIG) for tabview.

https://developer.apple.com/documentation/appkit/nstabview

The tab group in the lesson Mark linked to is a prior version of the tabview.

What seems to be different from HIG is that the textColor of the selected 
button is not set to black (to change that set the backgroundColor of the tab 
group to black.)
Additionally the buttons are semi transparent which seems to deviate from the 
HIG. There they look opaque.

Kind regards
Bernd

PS mouse messages work for me in the tab buttons which is what I would expect

Paul,

"current" is a synonym of "this".

When you search for "current" you will see "this" among the hits. Click on 
"this" and you will find "current" as a synonym.

LC dictionary does not list the synonyms as separate entries. TinyDictionary 
lists the synonyms thanks to Brian Milby who had the idea and coded that part.
There are about 350 synonyms in LCS.

I thought about why I used behaviors a little more.
What intrigued me was the idea that via a behavior a control was made aware of 
its neighbours. Be it a group or a control it knew where all the other objects 
were. Even dragged them along when needed.
And it worked semi autonomously with a little help from "the owner of this me".

I think that was my main fascination when using behaviors. It was a change of 
perspective from the central perspective to a decentralised perspective.

Actually I was experimenting and wanted to use behaviors dynamically at the 
time when I wrote this. A proof of principle if you want. It worked 
surprisingly well.
That is why I sticked to behaviors. After fixing some edge cases it even 
removes the behaviors correctly...
At the time there were no guides available for LC.

But as of LC 10 Guidelines will be part of the IDE and that looks and works 
really well. (LC uses a backScript)

Hi Bob,

There is an alternative for guide right now

https://livecodeshare.runrev.com/stack/1002/DevGuides-Plugin-Installer

and 10.0.0 DP4 has guides built-in. They look and work really well.

I will not develop bnGuides further since starting LC 10 they will be part of 
the IDE.
I liked the idea to push the concept of behaviors for guides. But maybe a bit 
too far.

Nevertheless the version of bnGuides Matthias linked to  in the Forum is one 
version step ahead of the one in Livecodeshare/Sample Stacks.

M1 Macs and LC 9.6.8 RCs and 10.0.0 RCs

[Niggemann, Bernd via use-livecode]

Sorry if this has been discussed before but I could not find it.

Yesterday I played around with LC 9.6.8 RC2 and 10.0.0 RC4 and wanted to see 
what difference the new Universal build does for speed.

After some testing I finally read the release notes and it states:
Note: Apple architecture support is currently experimental. To run the IDE 
using Apple architecture (on supported machines), you must toggle the Open 
using Rosetta option to off in the LiveCode.app bundle's Get Info pane in 
Finder. To build a standalone with native Apple architecture support you must 
explicitly choose the macOS Apple option in standalone settings.

For me the "Rosetta" box was not checked out of the box but LC ran in Rosetta 
mode.
Which means by default in the "Get Info" for the app "Use Rosetta" is unchecked 
but LC runs using Rosetta. You have to check "using Rosetta" and then right 
away uncheck "using Rosetta"
>From then on LC uses arm64.

I noticed some nice speed increase across all aspects of using LC: what used to 
take 10 seconds now takes 6.5 seconds. That is not bad for checking a box.

This only happens to me if I accidentally double-click on the icon in the

Changes in the topmost window and "applying" them do not change the variable. 
Apparently the lower window with the old values prevents that.

This is not the answer to "Why?" but it sort of does what you want

   local tProperty, tValue, tTarget, tResult
   
   put "dropShadow" into tProperty
   put "color" into tValue

   if the result is empty then
  answer "Property " & tProperty && tValue & " not found"
   else
  answer tProperty && tValue && tResult
   end if
end mouseUp

function fetchProperty pProperty, pValue, pTarget
   local tProp
   put the pProperty of pTarget into tProp
   if tProp is not an array then -- either single value (e.g. width) or empty
  return tProp
   else
  return tProp[pValue] -- either array value or empty

end fetchProperty

Just in case I did not make it clear: the behavior is removed when the 
selection of the dragged is, well, deselected. Independend of dragging.

To see that in the Properties inspector you would have to lock the Properties 
Inspector for that object and after deselecting the object you would have to 
change the tab in the Properties Inspector and go back to the "Behavior" tab to 
see that the behavior is gone.

Bob,
I assume that the behavior that sticks was added after you made the changes to 
bnGuides and that it is not a behavior that was added before you made the 
changes to bnGuides.
Maybe a short test with a new stack and a couple of controls that you inspect 
via Navigator while in Browse Mode.

Then I will have to investigate further because in my testing bnGuides does not 
add a behavior to a control when in "Browse" mode and Navigator or the Project 
Browser selects a control as a feedback for the target.

Not that I can see. bnGuides just stays out of this if Navigator or the Project

If you are in browse mode you will not and can not move controls around for

I think I know what is going on.

Navigator selects the object to indicate the target. That triggers a 
selectedObjectChanged message.

I naively assumed that would only happen when in "Edit mode" i.e. the tool is 
the "pointer tool"


If you add the following conditional to the card script in handler 
revSelectedObjectChanged



on revSelectedObjectChanged
   local tSelected, tSelectedOne

   ## dont set behavior if the tool is not "pointer tool"
   ## i.e. editing layout of controls
   if the tool <> "pointer tool" then
  exit revSelectedObjectChanged
   end if

you should be fine. I will have to put out a new version which catches that.

Bob,

the behavior used by bnGuides is set to a control. If that control already has 
a behavior/behaviors set then bnGuides
sets its behavior to the last in the chain of behaviors and removes it when the 
control is not selected anymore.

Do you have a recipe for an unremoved behavior set by bnGuides?

I have not tested bnGuides when revNavigator is in use. Maybe I should.

Re: oAuth2 window properties

[Niggemann, Bernd via use-livecode]

Hi Bob,

Have a look at "com.livecode.library.oauth2" in the Project Browser when "Show 
IDE Stacks in Lists" is on. That is the (library) stack that displays the 
information in a stack that is build on the fly.
It uses a browser widget to display.
You could change the dimensions of the browser widget. Additionally you could 
try to set the vScrollBar of the widget to false.
>From the dictionary for the browser widget
set the vScrollbar of widget to pEnabled

If you make changes to "com.livecode.library.oauth2" they will not stick: the 
next time you start Livecode they will be gone. If you want to make them 
permanent you would have to change the write permissions for that file in the 
app bundle on a Mac (Windows ??) and save your changes from the Script Editor.

I could not test my suggestions because I don't know anything about oauth2 but 
it should work.

Kind regards
Bernd

Re: Checking the Milliseconds

[Niggemann, Bernd via use-livecode]

I tried this and got pretty constant results except for maybe  the first ten 
iterations. I figured if you just jump in with the milliseconds you would not 
be at the "beginning" of the milliseconds and added a repeat loop to mitigate 
that effect. Furthermore I appended the result to a variable.

---
local last_known_millisecond
local queries = 0
local report
local longSecs, tMs

on mouseUp
   lock screen
   put empty into report
   
   --let it start at a flip of the ms
   repeat
  put the milliseconds into tMs
  if char -1 of tMs is 0 then
 exit repeat
  end if
   end repeat
   
   repeat 1000 times
  put 0 into queries
  put the long seconds into longSecs
  put the milliseconds into last_known_millisecond
  repeat forever
 add 1 to queries
 if the milliseconds = last_known_millisecond  then
next repeat
 else
exit repeat
 end if
  end repeat
  put queries && (the long seconds - longSecs) * 1000  & cr after report
   end repeat
   
   unlock screen
   put report
end mouseUp

I assume you have set the opaque of the polygon graphic to true?
Without "opaque" I do not get any filling, with "opaque" true it always fills

Thank you Trevor for making this available. After testing your library i 
realize what an improvement it is.
And I agree that "ideally any engine improvents would tap into the scroll wheel 
values provided by the OS"


I don't see any difference regarding lineSize. Maybe 
"ObjC_NSEventHasPreciseScrollingDeltas" is true.
Anyway in the comments of the LCB file you mention "row height"
Do you mean "effectiv lineSize" (synonym of borderSize) or "effective 
textHeight"?

I added hScroll to your script (again this is Mac only and needs Trevor's 
library installed)

I tested out the TimeZone library with a couple of randomly chosen timezones - 
and they all came back incorrect (i.e. unchanged from UTC even though the 
timezones should have been different). I know that if you pass in a timezone 
that is not in the local machine's database, it will silently return the UTC 
value - but that's not the case here.

I've now looked at it more closely - some of these timezones give the right 
answer, some give the wrong answer - though they are all in the TimeZones() 
list.


Alex,

After you mentioned the problems with the timezone library I had a look and it 
turns out that some of the timezones on the TimeZones() list are deprecated and 
they resolve to UTZ.
I forgot to post that I bug reported the problem in case anyone runs into it.

Hello Devin,

A rough guess is that she is on Big Sur. There is a known issue where
colorization is lost if the default font (Source Code Pro) is used. If this
is the case, she can try switching to a different font, and the issue will
be fixed.

Kind regards,

It  seems there is a new release of Source Code Pro that removes an 
experimental offending "SVG table with colored glyphs" from the font that 
causes the problem on Big Sur.

https://github.com/adobe-fonts/source-code-pro/releases/tag/2.032R-ro%2F1.052R-it%2F1.012R-VAR

Re: Bug: jumping stack windows (when supress messages is off)

[Niggemann, Bernd via use-livecode]

Hi David,

What I see on Mojave is that e.g. TextEdit or Safari show a similar behavior.
Open  2 windows in TextEdit.  Move one close to the other and they will snap 
into place, if the tops of those two windows are almost horizontally aligned 
they will snap into place.

Same goes for Safari with two windows open. And the  same happens in  the IDE.
If that is what you describe on a single monitor setup then it is an operating 
system thing.

Hi Michael,

This is because the "fixedLineHeight" is turned off by default since a couple

So you either turn "fixedLineHeight" on for the field or you change your code

 -- one line
set the vScroll of fld 1 to the formattedtop of line 60 of field 1 - (the top 
of field 1 + the borderwidth of field 1)

Re: Animation Engine: speed tips

[Niggemann, Bernd via use-livecode]

While not exactly what David asked for but on the topic  of animating multiple 
objects with acceptable speed:

http://forums.livecode.com/viewtopic.php?f=10&t=11726&hilit=sand#p56253

The original poster asked for "sand" particles that should have some sort of 
collision detection and should react to a mouseDown to either attract the 
objects or pushes them away.

It uses _one_ polygon graphic and sets individual points of that graphic 
(separated by an empty line). The points are just x,y coordinates and markers 
make the visual objects of the moving parts.

It manages to animate quite some number of objects depending on the size of the 
markers and some other features that are optional (dropshadow, ounteglow, 
markers filled and antialiasing)

The stack is completely useless but perfect for a rainy day at home. 
Depending on the complexity of the marker graphic it manages to animate 
smoothly (frame rate 18 and up)  from 150 to 1500 (small) objects (you can 
change appearance while the objects are moving.

For me Script profiler returns the handlers in order of time consumed, the top 
one used the most time

Then it reports the number of calls and the cumultive time for each line that 
was called. The times are relative to each other, not the real times without 
the overhead of the profiler. 
But they give a good indication of where the bottlenecks are.

presently it is possible to drag line = rows if you set

put true into pBool
dispatch "mtfAllowLineDragging" to group "modTableField 1" with pBool

Or set it from the helper stack tab "data"

You have to press the optionKey while dragging

Whereas you can extract columns from the data field but you can not set them 
nor drag them.
Again I will have to experiment to see how to eventually implement this.

I am not sure what that is. Are you talking about a spreadsheet like behavior 
with fixed left column and top row?

For sorting you can specify the sort.
However until now I felt that the developer is in control of the format of the 
data.
A predetermined format for a column would mean a lot of error checking on data 
input. I am not sure if it is not better to leave that to the developer.

If you plan to use modTableField in a project feel free to email me and I can 
see if we can work out some modification.

Re: How to find the column and row of a basic tableField

[Niggemann, Bernd via use-livecode]

Sean,

The idea for the script I posted was to be independent of the Livecode provided 
tableField.

My use case was that tab-delimited data was provided in a _regular_ field and 
the user clicks on a cell and the developer wants to know which cell was 
clicked to take action upon that information. That is what modTableField is all 
about. modTableField has an option for the user to fill/change cells within the 
provided tab-delimited matrix.
http://berndniggemann.on-rev.com/mtf/modTableField.zip

To make such a field you use the standard field and set its hGrid and vGrid to 
true. The revtablelibrary frontscript knows nothing about such a field and 
keeps out of it.

If however you want to use the built-in tableField to let the user enter data 
(that is what I gather from your comment) be aware that revTableField is not 
free of bugs.

https://quality.livecode.com/show_bug.cgi?id=21679

That bug may be of interest to you if you want to let the user enter 
information at arbitrary not yet created cells in a revTableField

But then again I may not understand your use case. If I can be of help feel 
free to mail me.

Kind regards
Bernd

How to find the column and row of a basic tableField

[Niggemann, Bernd via use-livecode]

There was a long thread regarding the dataGrid which somehow touched getting 
the row and column of a basic tableField.
I posted this solution also there. Mike Doub found some problems that turned 
out to be due to the fact that "cellEdit" was set to true for the table object.
If "cellEdit" is true then a front script takes over and creates a temporary 
field.

To post my solution to the problem again I start this new thread for clarity. 
The script is an elaboration on a sketchy script by Jacque.

The basic tableField is a regular field which has the option of "cellEditing". 
Apart from that it is a field that uses tab-delimited data to display it in a 
table form. 
hGrid and vGrid show horizontal and vertical dividers.

To get at the column number and the row number to determine the cell the user 
clicked on when the field's lockText is true here is a script that works well 
for me.

To test this make a regular field, name it "tf" and a second field for the 
result named "fRes". Make sure that "cellEdit" of the field is set to false 
(tab "table" in Properties Inspector)

set the script of field "tf" to 

---

Re: DataGrid question...

[Niggemann, Bernd via use-livecode]

Hello Mike,

I cannot reproduce the scrolling nor the failing of reporting.

What I did notice is when I changed the size of the field via the mouse in 
editMode at times switching back to browse mode via command-option-tab the 
field did not focus when clicking on it and it did not report anything. 
Apparently because it is not focused.

Make sure the field is focused by e.g. clicking on the card after resizing and 
then the field.
But there is nothing in the code that I can see that would take focus away from 
the field, nor does the code trigger scrolling.

Kind regards
Bernd

There is an interesting interaction between the scrolling function, the size of
the field, mouseUp or Down.  For my test, when I click the 6th column,
scrolling occurs and the function returns nothing.  If I size the field such
that no scrolling occurs, all works as expected.   If I change the mouseUp to
mouseDown, all works as expected.   I have not spent the time to figure out
what is going on, but these are my observations.

Re: DataGrid question...

[Niggemann, Bernd via use-livecode]

This is a modification of Jaque's script to get the row and column of a locked 
tableField when the user clicks in a cell.

Use tableField whose lockText is true. Set its script to



on mouseUp
   put "Row:" && word 2 of the clickline into tRow
   put "Col:" && getColumn(the clickH) into tColumn
   set the itemDelimiter to tab
   put tRow &cr& tColumn & cr & "ClickH: " & the clickH into field "fRes"
end mouseUp

function getColumn pClickH
   put the tabstops of me into tTabs
   put the num of items in tTabs into tNumStops
   if tNumStops > 1 then
  put last item of tTabs - item -2 of tTabs into tTabWidth
   else
  put item 1 of tTabs into tTabWidth
   end if
   set the itemdel to tab
   put the num of items in line 1 of me into tColumns
   if tNumStops < tColumns then -- add missing tabstops
  repeat with x = tNumStops+1 to tColumns
 put comma & (tTabWidth * x) after tTabs
  end repeat
   end if
   set the itemdel to comma
   put the hScroll of me into tHScroll
   put the borderwidth of me into tBrdr -- tested from 0 to 4
   put the leftMargin of me - 3 into tLeftMarg -- tested from 4 to 12
   put the left of me + tBrdr into tLeftAndBorder
   put tLeftAndBorder - tHScroll - tLeftMarg into tLeftOfItem
   put tLeftAndBorder - tHScroll + tLeftMarg + 1 into tRightOfItem -- + 1 is a 
fudge
   put 0 & comma before tTabs
   repeat with x = 1 to the num of items in tTabs
  if pClickH > (item x of tTabs) + tLeftOfItem and \
pClickH < (item x+1 of tTabs) + tRightOfItem then
 return x
  end if
   end repeat
   return empty
end getColumn



In my testing it works for changed borderWidth and margins, hscrolls and 
vScrolls

If you want to test it take a regular field, set its name to "tf", set its 
script to above script

and from a button apply this


-
on mouseUp
   put "1,2,3,4,5,6" into tLine
   put empty into field "tf"
   replace comma with tab in tLine
   set the itemDelimiter to tab
   repeat 6
  put tLine & cr after tCollect
  repeat with i = 1 to 6
 add 6 to item i of tLine
  end repeat
   end repeat
   delete last char of tCollect
   lock screen
   put tCollect into field "tf"
   set the hGrid of field "tf" to true
   set the vGrid of field "tf" to true
   set the hScrollbar of field "tf" to true
   set the tabStops of field "tf" to 77
   set the lockText of field "tf" to true
   unlock screen
end mouseUp

Here is a link to the latest version of modifiedTableField

berndniggemann.on-rev.com/mtf/modTableField.zip

there is a zip of a demo stack with a helper stack and a .rtf document with the 
API

Use the demo stack to explore modTableField. Have a little patience to explore. 
It shows many options. Please have a look at the API document to get a feeling 
how to address and query modTableField.

If you want to use modTableField in a project copy the group "modTableField 1" 
from the demo stack to your stack and use the API to work with it.

This version is HTML5 safe. There was a superfluous wait in former versions. 
Hermann used tinyDict with his HTML5 demo of an IDE.

tinyDictionary uses modTableField

There are a couple of users that seem quite content with modTableField (thanks 
Jerry for mentioning it)

I would be happy to know if anybody uses modTableField in a project. (aside 
from the people that mailed me before).

If you have questions please feel free to email me.

the styledArray does not include the returns at the end of a line. You have to 
add them if you address chars/codeUnits of the whole text. Initializing 
tTotalChars with -1 lets you add 1 to tTotalChars in each iterations of the 
outer repeat loop. -1 because the first line is not has no preceding return.
Also add 1 to calculate tStartChar otherwise you point to the last char of 
preceding run.

  put -1 into tTotalChars -- note -1
  put 0 into tStartChar
  repeat with i = 1 to the number of elements in tDataA
add 1 to tTotalChars -- account for returns
put tDataA[i]["runs"] into tRunsA

-- note add 1
put tTotalChars - len(tRunA["text"]) +1 into tStartChar -- mark char 1 of target

Additionally in your implementation if the target run with the metadata you 
look for is the last run of the array nothing is returned.

Re: Translate metadata to field content

[Niggemann, Bernd via use-livecode]

In reply to Mark Waddingham's comments


Thank you Mark Waddingham for the improved scripts and the hints as to why they 
improve speed.

I adapted Mark's version for unique occurrence, changed how the position of the 
target word is determined in the target line.
It is not safe to assume that the sum of words of the runs is the number of 
words of the line up to the target word. The reason is that runs are depending 
on formatting and formatting can create a new run in the middle of a word and 
thus increase word count.
I did not opt for Mark's use of codeunits because I had the impression it was 
not faster and makes the code less obvious.

--
local tTextOfRuns
repeat for each key i in tDataA
   local tRunsA
   put tDataA[i]["runs"] into tRunsA
   repeat for each key j in tRunsA
  if tRunsA[j]["metadata"] is tSearchText then
 repeat with m = 1 to j
put tRunsA[m]["text"] after tTextOfRuns
 end repeat
 put the number of words of tTextOfRuns into tNumWords
 put true into tFlagExit
 exit repeat
  end if
   end repeat
   if tFlagExit then
  exit repeat
   end if
end repeat
--
select word tNumWords of line i of field "x"

text consists of 96881 words and 23161 lines of heavily formatted text
(it is the script of RevDataGridLibraryBehaviorsDataGridButtonBehavior copied 
twice into a field as described before)

word# old new version, times in ms

96881 240 110
8 220 100
6 180  60
3 120 125
1  85 125
 1000  50  90
1  50  60

Timing this is a bit tricky. For "repeat with I = 1 to item 2 of the extents" 
it is obvious that time increases with increasing the target word number.

For "repeat for each key I in tDataA" it is not sequential but faster. However 
that also makes for variations in speed depending on the internal state of the 
array structure.

All timings are estimated averages of 5 to 10 measurements . Variability is 
typically about +-5 to 10 milliseconds with outliers.

However the overall speed gain is quite impressive and well worth the change.
I learned a lot about handling larger datasets using arrays, than you.

Kind regards
Bernd

>J. Landman Gay wrote:

>looks like the way to go.

There is no difference to using styledText for this use case. The number of 
lines and the number of words are the same between the  two.

You mentioned that you want to apply this to a huge text field.

I tested with the script of RevDataGridLibraryBehaviorsDataGridButtonBehavior 
which I copied twice into a field. That is about 23,000 lines and about 130,000 
runs.
This found a specific metadata of a word towards the end of the text in word 
80,000 of roughly 100,000 words in about 250 milliseconds (this excludes 
loading but includes hiliting of word and setting scroll, each about 25 ms).

However the loading time of styledText a little more than 300 milliseconds (no 
difference between styledText and formattedStyledText, but htmlText loading of 
this heavily formatted text is 800 ms). 

If you can manage preloading of the styledText into e.g. a script local 
variable at startUp or openCard or first run it would save more than half of 
the processing time.

here is Richard's script which I changed to get the number of words of the line 
with the tagged word, the number of lines are taken from the array.

The tagged word is then: word tNumWords of line (current array key)

-
put item 2 of the extents of tDataA into tExtents
   repeat with i = 1 to tExtents
  put item 2 of the extents of tDataA[i]["runs"] into tCounter
  repeat with j = 1 to tCounter
 if tDataA[i]["runs"][j]["metadata"] is tSearchText then
repeat with m = 1 to j
   add the number of words of tDataA[i]["runs"][m]["text"] to 
tNumWords
end repeat
put true into tFlagExit
exit repeat
 end if
  end repeat
  if tFlagExit then exit repeat
   end repeat
-

select word tNumWords of line i of field "x"

RE: Translate metadata to field content

[Niggemann, Bernd via use-livecode]

My previous post was accidentally marking a part of my response as quoting 
Ralph's question.



This is my response to Ralph's question about the difference between

styledText versus formattedStyledText



>From what I tested it behaves the same as formattedText. I.e. if you have
wrapped text in a field it will keep the wraps when transferring to another
field although the destination field is wide enough to hold the text
unwrapped. Of course formattedText is on raw text and does not include styling.

Whereas formattedText inserts returns at the wrapping formattedStyledText
inserts vertical tabs = ASCII 11.

Thus the number of lines returns the same value when using formattedStyledText
whereas formattedText increases the number of lines if there is any wrapping.

Kind regards
Bernd

Re: Nested numeric lists that include number of parent list item

[Niggemann, Bernd via use-livecode]

I am not aware that listStyle decimal can show other then 1. No further sub 
numbering.

However one could hack it. Although I know you are not particularly fond of 
those hacks...

The code assumes that the listStyle of a field is set (any) will be "skip" 
afterwards and list depth is also set.


--
on mouseUp
   local tDepthValue, tTab, tDepth, tLastDepthValue
   local tIndex, tLeadingSpaces
   lock screen
   put space & space into tLeadingSpaces
   put numToCodePoint(9) into tTab -- not used

   put 0 into tDepthValue
   put 0 into tLastDepthValue

   set the listStyle of line 1 to -1 of field 1 to "skip"

   repeat with i = 1 to the number of lines of field 1
  if line i of field 1 is empty then next repeat
  put the listDepth of line i of field 1 into tDepth
  add 1 to item tDepth of tDepthValue
  if tDepth < the number of items of tLastDepthValue then
 delete item tDepth + 1 to -1 of tDepthValue
  end if
  put tDepthValue into tIndex
  replace comma with "." in tIndex
  put "." after tIndex
  put tIndex & tLeadingSpaces before line i of field 1
  put tDepthValue into tLastDepthValue
   end repeat
end mouseUp


to remove the hack

-
on mouseUp
   set the itemDelimiter to "." & space & space
   lock screen
   repeat with i = 1 to the number of lines of field 1
  if the number of items of line i of field 1 > 1 then
 delete item 1 of line i of field 1
  end if
   end repeat
   unlock screen
end mouseUp
-

It prepends the text with a decimal index. I started with tab as separator but 
it does not look well. Now it is two spaces. One could use non-breaking spaces 
as separators.

Kind regards
Bernd

Re: Diff?

Richard,

Library com.livecode.library.diff was introduce in 9.0

diff library
A new library has been implemented for computing diffs between text sources and 
applying those diffs to text.

https://github.com/livecode/livecode/blob/develop/extensions/script-libraries/diff/diff.livecodescript

I have used it occasionally and it worked well once you get the syntax right 
and find out what it does.
Especially in

DiffCompare(pFrom,pTo,pContext)

how pContext works. It takes a little experimentation.

Re: OMG text processing performance 6.7 - 9.5

[Niggemann, Bernd via use-livecode]

Ben,

If you have access to a business-license you could use "script profiling" on a 
small but representative sample of your data and see where the bottlenecks are. 
If you find any you could try to optimize that part.

"script profiling" adds its own overhead to the processing time (roughly 
doubles it) but if you keep the sample small it is well worth it in my 
experience.

Hello,

With livecode 9.6 I have a strange behavior, when the custom property inspector 
is open, and the script window is open too, the focus shifts from time to time 
to the property title (which I previously displayed). If I don't pay attention, 
I replace the property title with the script I'm writing!

With LV 9.0, I didn't notice this behavior.

I?m the only one with this bug ?

Thanks (and Happy New year !) !

I spoke too soon. When I tested, I hard-coded a value as the filter

elements of the array all start with a 4-character string followed by an
underscore, for example:  ER01_some text here

My variable contains "ER01":

  put tVar & "_*" into tFilter
  filter elements of sArray with tFilter into tNewArray

No go. I've tried a few different iterations. However, this works:

  filter elements of sArray with "ER01_*" into tNewArray


This works for me in 9.0.4 and 9.5 DP1


on mouseUp
   local tErr = "ER01"
   local tArray, tVar, tNewArray

   put (tErr & "_*") into tVar

   repeat with i = 1 to 17
  if i mod 2 is 1 then
 put tErr & "_" & i into tArray[i]
  else
 put i into tArray[i]
  end if
   end repeat
   breakpoint
   filter elements of tArray with tVar into tNewArray
   breakpoint

If anybody is interested in this version please mail me and I will send it. If 
there is enough demand I will update tinyDict on Livecodeshare. Otherwise I 
will update tinyDict when there are more changes/bugfixes.
Currently there is only a fix for a minor display glitch. Not really worth an 
update.

Otherwise please report issues/bugs and I will see if I can fix them.

Kind regards
Bernd
