Re: Setting conditional breakpoints

[Tom Glod via use-livecode]

oh you can open up the engine to do other handlers by using "in time"

I use it all the time..I have a message checking hotkeys clipboard
changes and it works beautifully.


on CheckIfVisible
if the visible of defaultstack = true then
send "CheckIfVisible" to defaultstack in 100 milliseconds
else
end if
end CheckIfVisible

Re: Setting conditional breakpoints

Set a breakpoint, right click it, choose condition, and fill out the 
dialog. That's how I usually do it.

Re: Filter an array by content

[J. Landman Gay via use-livecode]

Mark Talluto's bug is exactly what I see. It may be related to a certain 
type of scripting, or a particular sequence of commands. I crashed several 
times in a row within a minute of a restart, so maybe the handler I was 
debugging was to blame.

On Mac, a huge dialog appears with the crash log in it. I select all, copy,

there's a system log (like Console displays on Mac) it's probably in there.



(And is it worthwhile me getting some of them to add to the bug reports?)


Good question. I've uploaded maybe 20-25 of them so far. I don't always 
bother any more.


Now that I've discovered breakpoints don't crash as long as I don't step 
through, I was able to see what's going on.


I was wrong. Not more than a few minutes ago I crashed after stopping at 
multiple breakpoints. It doesn't seem to matter if they're red-dot or 
typed. However, it seems to take more repetitions before the crash if you 
don't do any stepping.


Hmmm - I find I have no choice but to step through; the editor/debugger so 
often "freezes" (i.e. when I scroll the text, the line numbers don't scroll 
at the same time).


I see that all the time. If you step over, the dot location fixes itself at 
least here. Until the crash, anyway. It doesn't crash right away, it seems 
to be a cumulative thing, so you get a few chances before everything goes down.


This has really been crippling my productivity. I'm sure it's a very 
elusive thing to track down but I hope they can find it. If no one else has 
a problem, it may be something script-related that both you and I are doing.



So I can't just set another breakpoint further down - I have to step over 
for a while until the place at which I want to set the breakpoint scrolls 
itself into view.


If you have experienced crashes during debugging, take a look at 
https://quality.livecode.com/show_bug.cgi?id=22130 and

Re: Setting conditional breakpoints

That would be true if the engine was multithreaded. As it is, I am trying to 
find the line of script that is changing the property, and until the script 
terminates, no other script can run.

Re: Setting conditional breakpoints

OK looks like setting a breakpoint on a property change like the visible of a 
stack can't be done. Might be a nice addition though. Let's say you have a 
custom property that keeps getting corrupted (by which I mean it contains bad 
data) and you want to catch it in the act. Wouldn't it be nice to be able to 
set a breakpoint for a property like you can for a variable? 

I'll file an enhancement request.

Hi all. 

How do I set a conditional breakpoint based upon a property? I tried using the 
visible of stack "Forms Generator" is true, but I cannot enable the breakpoint 
and it says there is no condition, even though there it is!

so often "freezes" (i.e. when I scroll the text, the line numbers don't 
scroll at the same time). So I can't just set another breakpoint further 
down - I have to step over for a while until the place at which I want 
to set the breakpoint scrolls itself into view.


If you have experienced crashes during debugging, take a look at 
https://quality.livecode.com/show_bug.cgi?id=22130 and

Re: Help with drawing in LiveCode...

You are still focused on tool switching and control selecting. That is fine, 
but is that the main and only issue for you? We can work on that, the goal 
being that you modify the current behavior of LC to the behavior of the old one 
you are used to.
I do not need that, since the entirety of my drawing is created under script 
control. So may I request that you post to the forum? I am much more 
comfortable there, and we can all propose handlers that will restore the old 
way.
Did you try the handler I posted earlier? It is a good start.

I implemented a fairly complex drawing module to a stack we use all the time. 
It isn't CAD, but it looks like it, albeit rather less professional looking

We send these drawings out daily to clients. They are based on data calculated 
within the stack, and use graphic objects galore.
But our drawings are one-way, that is, once drawn, they are complete, and are 
forwarded as PDF's. You are looking to be able to manipulate objects (in CAD 
parlance) live on screen. In a CAD environment an object that has been selected 
remains so, regardless of tool or property changes, until either nothing is 
selected or one or more (other or additional) objects are explicitly selected.
This should not be a problem, once some tools are in place, such as the one you 
are asking for with auto re-selection of controls based on recent activity. But 
that is just gadgetry, and once set up, should allow you to do whatever you 
want to.
I would be glad to show you what I make, if that will at least give you an idea 
of how far you can take drawing in LC. But remember, LC is not a drawing or CAD 
program. But you can make it act like one. You just have to change some of the 
built-in rules.
Craig


Thank you. You example sounds closes to what I am looking for. The old
stack I have uses a technique of switching the tool from the browse tool
(when a user need to click on tool icons or menus or whatever to the
appropriate vector drawing tool when the mouse is over the drawing area,
including the pointer tool for selecting, dragging, or resizing existing
graphic objects created using other tools.

The difference is, in the old stack under LC4.6.4 of an object is
selected (say a rectangle) and the tool is set back to browse to click
on a color palette (or whatever), the object remains selected. However,
under LC9 it does not. Or if it is something in the old code of the
stack I can't figure out what. That's why I am looking for an example to
learn from.

I'd appreciate taking a look at your stack.

Re: Filter an array by content

[J. Landman Gay via use-livecode]

Found the problem. My script local was being emptied for some reason, so 
there was nothing to filter. After repopulating all data it worked.


My only excuse is that I've been avoiding stepping through the debugger 
because LC has been crashing when I do that. I've sent in many crash 
logs but it's only recently I've discovered it happens only with Step 
Over. It's hard to believe no one else has seen this, which I've been 
seeing since LC 9 first came out, but that's why I didn't know what was 
in the variable. Now that I've discovered breakpoints don't crash as 
long as I don't step through, I was able to see what's going on.


If you have experienced crashes during debugging, take a look at 
https://quality.livecode.com/show_bug.cgi?id=22130 and 
https://quality.livecode.com/show_bug.cgi?id=21876

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

This works for me in 9.0.4 and 9.5 DP1

local tArray, tVar, tNewArray

put (tErr & "_*") into tVar

Re: Filter an array by content

Hi Bob,

It sounds like your library is something I could benefit from :-)

I know it's been mentioned on the list before, but I've lost track of 
where to get it from, and  a quick search didn't turn anything up. Could 
you please send a reminder (either to the list or direct to me if you 
prefer).


Thanks

Alex.

Hi Tom.

So the little benchmarking I did originally showed that my method was a little 
longer, as I still have to iterate once through the array to populate the 
database. Where it really shines is that you can do complex queries, as well as 
multiple column sorts before converting back to an array. Also, if you need to 
make multiple passes at the data, the speed of course exceeds iterating through 
the array again and again. Finally, since it's in a database, it's persistent 
through idle, whereas an array would have to be stored in a script local or a 
property if you needed it across runtime sessions.

I have a tendency to think that any operation i perform to convert an

items in the dataset. But for my particular use at the moment, I find LC
performance to be excellent.

Bob I'm interested in your library..mostly learning the point at which
it makes sense to do that conversion and what kind of speedups can

I wonder whether explicitly specifying "wildcard pattern" would fix this.

(I misread your query as referring to arrays with numeric elements, not arrays 
with numeric keys. Thus, my fascination with the new "where" where one can use 
"each > 22.2". Even with your use, "where" might be interesting.)

Re: Filter an array by content

[J. Landman Gay via use-livecode]

I spoke too soon. When I tested, I hard-coded a value as the filter 
string. But when I use a variable, it fails as it did before. The 
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

Even with no matches though, Tom was right. Looping through the keys 
takes 0.03 milliseconds. Filtering takes 0.22 ms.

Thanks to all for the replies. Monte, I didn't see your post until Tom 
quoted it, for some reason it didn't arrive here.


At any rate, I'd already tried "filter elements of..." and it failed 
which is why I posted. But I must have had my filter wrong because I 
just tried it again and it worked. So that part's solved.


And I found something interesting: when I filter a numeric array, the 
keys remain attached and since they are numeric, they're in order. Fancy 
that. :)


All is well. Thanks guys.
