Re: Go to card has become slow

[Richard Gaskin via use-livecode]

Great test set, Neville. Thanks for posting that link.

The hardware on my Linux and Win boxes is so different I don't have a 
strong opinion there. But I did modify your main test script to see what 
I might learn from isolating the file I/O from the stack serialization:


on mouseUp
  put word 2 of the long name of stack "data" into fName
  replace quote with "" in fName
  if the shiftKey is "up" then
put the long seconds into t0
save stack "data"
put the long seconds - t0 into t1
put "saving data took " && t1 && "seconds" into fld "timeInfo"
put 0.01*(the length of URL ("file:" & fName)) && "MB" into fld 
"lengthInfo"

  else
put url ("binfile:") into tData
put the long seconds into t
put tData into url ("binfile:"& fName)
put the long seconds - t
  end if
end mouseUp

So I ran your tool, making a stack with 300 cards, which produces a file 
a bit over 8MB.  These are my times:


Ubuntu 18.04 w/SSD
Stack: 0.097182
File:  0.008475

Windows 10 w/HDD
Stack: 8.183708
File:  0.014

Even with the differences in the hardware, it looks like the bottleneck 
is in the stack serialization, and the file I/O seems good.


Anyone here in a position to run Neville's test with this modification 
on similarly-configured systems but different OSes?

I don’t know why the test stacks I supplied disappeared from the QC bug report.

You need the SlowSave.livecode and the data.livecode stacks. They are both 
small, but SlowSave creates a large stack with 300 cards and the lorem ipsum 
text data to build an 8 MB stack, and displays the timing for saving. On my 
MacBook Air it takes 0.13 seconds to save; on Windows 10 installations I have 
seen times from 3 seconds to 10 seconds.

In this test, the stack has just 300 cards, 1 field on each, and lots of ascii 
text (so there should be no problems converting to utf-8 before saving in the 
unlikely event that is happening, and in any case would happen on all 
platforms). I haven’t tested stacks with large numbers of controls or large 
images rather than large text data.

Other apps on Windows 10 certainly don’t display this behaviour, which  
indicates it is a LC problem not a Windows problem. Antivirus software and 
Defender were off during the test. I was under the impression that saving files 
from LC, rather than stacks, was not slower than normal, but Bob’s recently 
experience with saving data to a database may contradict that.

Some people have had trouble verifying my observations (other LC Forum users have confirmed). QC originally could not confirm the bug until they tried it “on an older PC”. However one of my users recently updated to a *very* fast HP box; it cut the save time down significantly but was still at least 20 times slower than on a typical Mac, ie almost usable. So maybe it has something to do with the Windows installation, though the ones I used were stock standard. I can’t see how fonts could be involved, for example.

Agreed. Focusing on a field if you need to is simple and can be achieved
using one line of code. Plus, by coding it you don’t have to worry about
the wrong field obtaining focus if you change the layering order of
controls later on.

I have workarounds, I just don't want to have to use them. Selecting nothing or setting the 
hilitedline, either one, you still have to set up some handlers to do it. They don't work in an 
openCard handler, you have to reset after that.

The workaround is tedious: on preOpenCard, set traversalOn to false, send a

will catch the message and do the deed.

I want a property or setting that lets me turn off this default behavior. It's 
annoying and disruptive, and has been there since day one.

Re: Building a Board Game

[Devin Asay via use-livecode]

Roger,

Rather than moving an object, think about using button icons.  This is the 
basic process:

- on mouseDown: check the icon of the target, set the icon of a hidden, moving 
button to the same icon, set the icon of the target to 0, set a 
flag—isDragging--to true, show the hidden button

- on mouseMove: if isDragging is true, set the loc of the moving button to the 
mouseLoc

- on mouseUp: figure out which square you’re over, set the icon of that button 
to the icon of the moving button, hide moving button, set isDragging to false.

I made a rudimentary chess game that uses this technique, check it out here:

http://dight310.byu.edu/lesson_materials/07-arrays/chessGame-final-key.livecode

Click the Clear Board and Setup Game buttons first to set up the game board 
array. Game state handlers are in the card script; game piece moving handlers 
are in the game board group script.

Hope this helps.

Devin

Re: Building a Board Game

[Bob Sneidar via use-livecode]

Just brainstorming, you would have to intercept mouseMove and then have a 
tolerance of points to your grid. Say three points. Assuming your grid starts 
at the top left of the window, you would div the top of the object with the 
vertical grid width, check for tolerance above and below, then set the object’s 
top to the nearest gridline. You will also need to set the mouseLoc by the same 
amount, or else capture the mouseLoc on mouseDown, record the distance from the 
top left of the object, then after setting the top left of the object, opined 
the mouseLoc to the object again. Do the same with left, and also with bottom 
and right if need be.

Re: Building a Board Game

[Tore Nilsen via use-livecode]

What I do is to make a grid of named rectangles (they may or may not be 
visible). I put the names of these into a variable or an array. On mouseUp I 
traverse the variabel/array to check if the mouseLoc is within any of the 
rectangles. When there is a match I set the loc of the grabbed control to the 
loc of the matching rectangle.

I will put in a pull request after the release for adding the iconFill property 
now that is does not change the default behavior. I know it's been asked and

The PR is now merged into develop and will be in the next DP.  It only adds the

work up a PR for the other piece, but I’m not sure about how that one works 
without downloading and testing (sounds like an option to hide the label on

Building a Board Game

RE: HilitedItem of a navbar

[Ralph DiMola via use-livecode]

I have changed my version to leave the selected it default to 1. This will not 
change the original behavior but allow you to set it to 0 by script or in the 
PI. Of course one can set it to zero in a preopencard handler so it initially 
displays with no item selected.
I added a property call iconFill that is defaulted to off so the widget will 
still retain the original behavior. If this property is set to true by script 
or ticked in the PI then the icon will fill the height of the widget if the 
label is set to empty. So...

1) The hiliteditem can be set to zero so no item is highlighted
2) The default hiliteditem has not been changed.
3) The PI allows you to decrement the select item index to zero.
4) If the label of an item is empty and the iconFill property is set to true 
then the icon is centered vertically and fills the height the same as when 
"icon only" is selected.

New version is available for evaluation at:

The PR is now merged into develop and will be in the next DP.  It only adds the

work up a PR for the other piece, but I’m not sure about how that one works

Re: Go to card has become slow

[Bob Sneidar via use-livecode]

Richard, I can verify that my mainStack is pretty big in terms of objects and 
code. When I create a standalone for Windows however, it breaks out all the 
substacks into individual stacks, and the saving just the mainStack in a 
Windows standalone still takes longer than saving the entire Mainstack with 
Substacks on the Mac. 

As a countermeasure, I suppose I can work on getting all the scripts I can 
moved into script only behaviors. I still make extensive use of Datagrids 
however which have a lot of objects. Most of my substacks have multiple grids 
and the main stack has 7. 

I will also say that I have seen a considerable speed difference between Mac 
and Windows when expanding a fairly large zip file contains lots of individual 
files and folders (copier firmware to be exact), so I do not thing the issue is 
with the LC engine, or at least not entirely. It’s so prevalent that I don’t 
even use windows to expand these files anymore.

Thank you for the link to that report, Nevile.  While I have been a 
subscriber to it I also follow many reports, so your link is very helpful.


I was eager to run the test stack there, but discovered there isn't one. 
 I don't mind creating one, but it would be helpful to know what's 
required.


Have you seen any difference between a stack with little content but a 
large number of objects vs one with a small number of objects but a lot 
of text or images?


Once I can reproduce the test, I'll modify it to isolate the time 
devoted to stack files separately from other file I/O for 
equivalently-sized files.

Re: Getting started with geographical coordinates

[Graham Samuel via use-livecode]

Thanks for everyone who has helped with this so far. I have now looked at and 
tested LC scripts for three different functions for finding the distance - I 
left one well-known one out (Vincenty) as it’s very complex (it even includes 
iteration) and I think not justified by what I’m trying to do. As I’m concerned 
with relatively small distances (up to a few kilometres), I can include a 
Pythagoras calculation (officially called "Equirectangular approximation”), 
which doesn’t take account of the curvature of the Earth. My tests have 
involved real coordinates of places I’ve visited, so can be verified using 
local maps etc.

What I have found is that the different methods are all good for my purposes, 
but for me the very simple Pythagoras calculation which involves only two maths 
functions, gives results which are consistently less than one percent different 
from the far more complex Haversine and even Vincenty calculations. 
Incidentally I get differences in Haversine between my implementation (based on 
Ralph’s, thanks) and Chris Veness’s (movable-type)  Javascript version - I’m 
pretty sure this is due to differences in precision in the underlying maths 
functions, but I don’t plan to look any further into that!

Just FYI, here’s the Pythagoras method. The inputs are assumed to be numerical 
GPS-style coordinates, which is what one gets from interrogating a GPS-aware 
device in LC. The result is in kilometres.

constant R=6371 -- the radius of the earth in kilometres
constant k1 = 0.01745329 -- that's pi/180

function distancePythag lat1,lon1,lat2,lon2
-- Calculate Distance between to points using Equirectangular approximation
-- Assuming a (local) flat surface, using Pythagoras. Won't work when Earth's 
curvature is significant
   local x,y
   put k1*lat1 into lat1
   put k1*lat2 into lat2
   put k1*lon1 into lon1
   put k1*lon2 into lon2
   put (lon2-lon1) * cos((lat1+lat2)/2) into x
   put (lat2 - lat1) into y
   return sqrt(x*x+y*y)*R
end distancePythag
