Re: Quick IDE question

Can you explicitly set the rect of the SE? I do this all the time because I 
have it located on a large vertically oriented monitor adjacent to my main 
screen, and the loc needs to be refreshed now and then depending on other stuff 
I use them for.

Subject: Quick IDE question

Since yesterday, running either LC 9.5.1  or 9.6.0 dp4 on a Mac, every time I 
open the Script Editor window, it overfills my screen, so I can’t see the 
bottom of the window. There are no decorations, so I can’t resize or minimise 
the window; and dragging the window by the title bar doesn’t work either. I’ve 
restarted both versions but no joy. Everything else seems to be working 
normally and the other LC windows have decorations.

I don’t believe I’ve ever seen this before. Does anyone know how I can get out 
of it?

Bill, I think you’re right about the Guide not being searchable. I was going to 
point it out myself, but I began to think that I had used up my grumbling 
allowance, or at least I had not much left and needed to use it for other 
things.

Of course the Giude should be searchable!

Re grumbling - I have always been delighted by the way people on this list come 
to each other’s aid. This ‘invisible college’ is a really essential part of the 
LiveCode experience, I believe. I hope I say ‘thank you’ enough.

Maybe. The list may be expecting different line endings than AOL provides. What 
we usually see 
when people paste here from the SE is a bunch of markup symbols, but the 
carriage returns 
generally come through okay.

Here's a copy/paste test from my LC editor, let's see what happens:

Pay no attention to the previous post, which only dealt with a single integer. 
Sloppy.
THIS old fashioned method works, though:
on mouseUpput offset("(",yourString) into startCharput offset(")", yourString) 
into endCharput random(999) into char (startChar + 1) to (endChar -1) of

If you’re certain that this is the only, or even the first, integer, a regular

I have a very long string.

In the middle-end part of the string I have “(x)” where x represents some 
integer.
it could be (4) or (10) or (5) etc.

I just want to replace the number inside the () with whatever other number I 
need to.

I have been trying to find an easy way to do this.  Ideally a wildcard 
character like ? or *
would probably do it, but after going through the dictionary and getting lost

The ‘is strictly’ operators allow you to detect what the actual internal 
storage type of a value is. Some things generate numbers which are stored as 
int32s but most will store them as doubles - arithmetic operators included.

I don’t know what the docs say about ‘is strictly an integer’ but the operators 
themselves are definitely doing as they should so the docs might need some 
refinement :)

Mark

P.S. The ‘is strictly’ operators were not really added for general use as they 
are tied to internal mechanisms. They were added to help with doing faithful 
export of values (lcVCS way back IIRC).

Re: Groups placed on cards

I am intrigued that you have a particular stack where this (standard) behavior 
does not happen. Can you change the group script at each instance? Can you 
change the locs of the controls that comprise it? That sort of thing.
Such a stack might be of real interest to the team.

Re: Groups placed on cards

[dunbarx--- via use-livecode]

Peter.
If you have a stack with one card, create a group, and set the 
backGroundBehavior of the group, then any new card you create will 
automatically contain a copy of the group.
If you already have a stack with multiple cards, and create a group somewhere, 
then if you want to copy it to other cards it to be done with the "place" 
command.
You can always add or delete groups with LC gadgetry.
What you really asked, though, was whether the same group that appears on 
multiple cards can each have unique scripts based on the particular instance of 
any of them. I am not sure that group scripts can be so compartmentalized. That 
is why I invited others to chime in. The workaround I mentioned is just that, a 
workaround, unless some combination of properties will allow the "same" group 
to hold its own unique script.

Re: Groups placed on cards

[dunbarx--- via use-livecode]

Hi.
You can certainly create a group and set its backgroundbehjavior, then "place" 
it on any or all existing cards. This assumes that the group comes after the 
multi-card stack. Then any changes to the physical structure of your group will 
appear in all instances.
But I am not sure how you would separate the scripts of such a group. Others 
may know better.
You can always, however, tailor the group script to detect the card it is on,

Subject: Groups placed on cards

Hi,

I have a stack with multiple cards (not part of a background) and I want to 
place a group on each card—the same group--AND be able to edit a single group 
script.  And ideally, I would be able to configure as needed the controls of 
all instances of the group from a single location.

For example, I have a glossary in a separate stack in another window, but now 
want to incorporate that stack to display as a pop-down in the main stack 
window on each (non-background) card. 

In testing, I’m seeing each placement of the group now as a new object.

This is for both Mac and Windows.

What would be my options to manage this?

Thanks,

Peter Bogdanoff

Re: Visual Effect

[dunbarx--- via use-livecode]

Hi.
I never use visual effects, but I think you may need to go to the dictionary.
One thing it says is:
 "The visual effect command affects only navigation within a window. If you 
want to create a transition effect when moving between stacks, use the go...in 
window form of the go command :
visual effect wipe downgo stack Index in window Part 2 -- replaces stack on

I’m having trouble wrapping my head around visual effects. I’ trying to hide 
and show stacks using visual effects. 

Consider this in a button:

on mouseUp
  wait 1 second
  set the visible of homeStack() to false 
  lock screen
  set the visible of homeStack() to true
  unlock screen with visual effect reveal down very slow
  breakpoint
end mouseUp

homestack() simply returns the file path of the main stack, which this button 
is on. 

The visual result is indistinguishable from simply showing and hiding the 
stack.

Re: Long Standing Issue with the defaultStack

[dunbarx--- via use-livecode]

Hi.
I know that doing the simplest things, breathing, going down to the message 
box, can upset the defaultStack. I see this often when trying to change 
properties in open inspector(s).
My example may have been unfair to your issue, because I wound it so tightly 
within a single short handler. There was no room for fiddling around, by you or 
LC.
When one is roaming around the IDE, I think I have seen the same things you 
have.

Not sure at this point. When I open a sub stack called “Devices” (or any sub 
stack) of my main stack “Forms Generator” and I enter “put the defaultStack” in 
the message box, I get “Forms Generator”. 

If I put the command “put the defaultStack” in the last line of the openStack 
handler of stack devices, I get “Devices”. 

Right afterwards, if I enter “put the defaultStack” in the message box, I get 
“Forms Generator” again! 

Not entirely sure what is doing it. Had the same issue with another much 
simpler stack. If I went invisible to a database setup stack, then went back to 
the stack that called it, the defaultStack remained the database setup stack, 
and THAT wasn’t even a sub stack! 

Until I can figure out what is causing it, I cannot trust the defaultStack.

Hi all. 

I think I have stumbled across what appears to be a bug. When I open a sub 
stack from a main stack script, the main stack remains the defaultStack. This 
is causing any number of issues with me. I have a closeStackRequest handler for 
instance that auto saves the stack. It never gets triggered because the 
closeStack message never gets sent to it! 

If I open a stack, shouldn’t THAT STACK become the default, barring modal or 
system stacks?

Re: Tab In Field

A bit of LC lore from the dictionary:

If the user presses the  key while editing a field, normally the
insertion point moves to the next control whose traversalOn property is
true. If the tabStops property is not empty, the user can enter tab
characters in the field. Each time the Tab key is pressed, the insertion
point moves to the next tab stop on the current line.

Hi.
I may not really understand what you want, but doesn't the "Find string" 
variant solve your problem?
If you have a field 1 with "cat" on line 1, with "cât" on line 2 and "cat" on 
line 3, that is, the line 2 "cat" has charToNum(137) in place of the standard 
"a".
on mouseUpfind string numToChar(137) in fld 1put the number of words in char 1 
to word 2 of the foundChunk of fld 1 into tempanswer "Word" && temp && "="&& 
word temp of fld 1end mouseUp
The point being that once you have the result of "find String", you can 
engineer all the other stuff you need, such as the words that contain the odd 
char, the lines they reside in, etc.

Hi,

I have a text search that in which I’m trying to improve the UI.

I have this text:

Edgard Varèse (Poème électronique) was a pioneer in the application of tape 
recording technology to composition.

The search database, built with Scott McDonald’s rrpSearch plugin, can only be 
searched using the exact characters. So, I’m building a supplementary array of 
words with alternate spellings that the user might type in the search box. I 
would reference the array to get an equivalent word and so provide the user 
with a usable result.

So if the user types in “poeme” — I would find “poeme” in the array and its 
equivalent “Poème” and I would actually search for “Poème” — and the user would 
get a result that included “Poème”.


So I want to build this array of word equivalents. The search database is built 
by rrpSearch from text on cards, so I have to go back to these cards to get my 
data. I’m using the find command to search cards to find every instance of  “è” 
or “é” or “ü” or “î” or whatever. There are many non-English words in the text. 
The foundText function should give me the words that contain that 
character—except it doesn’t in every case. It only finds words that BEGIN with 
the search text. So

électronique — found (char begins the word)
Varèse — not found (char is in middle of the word)
Poème — not found (char is in middle of the word)

I’m using “find” and “the foundText” which returns the whole word that contains 
the search character. No other form of find will return the whole word. The 
dictionary for foundText:



Is there another relatively simple way to get the whole word in which the 
desired characters live? There are dozens of fields on thousands of cards to 
search.

(I realize that there are far better ways to handle a search, and in the 
future, I will have a database that I will design myself--but not yet.)

Thanks,

Peter Bogdanoff

Re: Stacks and Custom properties

[dunbarx--- via use-livecode]

Sure. Any object that has an inspector, and that means everything, can hold 
custom properties. Open the stack inspector and check it out.
The trick is to know where to place these things. It depends on what is going 
to need them. In a sense, you might think they ought to fall into some sort of 
"message hierarchy", but since they are always explicitly referenced, this is 
not strictly true. You generally place them according you your own sense of 
structure.

Never in the IDE, frequently in the iOS standalone, sometimes in the Android 
app. It seems to 
depend on how long you use the app. I have never had a crash because I do unit 
testing and then 
quit. The testers pound on it hard and they get most of the crashes because 
they're at it for 
hours. On the other hand, my client took the Android app to a trade show and 
demo'ed it for 8 
hours a day and never crashed. So maybe it's device-dependent? Who knows. My 
primary tester has 
a budget Moto phone, my client has a Pixel 2. That's why I'm thinking it may be 
memory-related.

Both intermittent, not reproducible on demand, and never consistent. A logger 
would probably be 
difficult to deal with on a mobile device, but more importantly, it could only 
tell us what 
actions the user took before the crash. Since we've tried repeating the same 
actions many times 
without any problem, there's really nothing to point a finger at.

The earliest build I did was in 9.0-something but the testers never got the 
mobile app until I 
built with 9.5.1 so I'm not sure. I should have said "goes back at least to 
9.5.1."

Curry.
We are all fortunate in that you found the culprit in a single command in a 
line of code.
It crashes LC 9.5.1 in Mac OS. If I change the second parameter (tDel) to a 
single char, all is well,
The issues I am having with my project occur in random places in different 
handlers at random times.
This is not stopping me. Saving often allows me to forge ahead, with good

Chiming in again since it dovetails with today's work:

Crashing bugs (and others) sometimes require a missing 
factor/context/detail in the original real-world project that is tricky 
to reproduce in independent test stacks. You have to compensate for that.

I filed this crasher today, but had to use a slightly more "extreme" 
example compared to the original real-project-crasher to get 100%

Re: Diagnosing a crasher (was Re: Quality, reputation, and improving both)

[dunbarx--- via use-livecode]

Richard.
 I will keep a eye out to see if something I do or some particular section of 
code which causes a crash. 
I have no issue with sending you my stack; it is only for internal use. But 
there are many handlers in many controls on many cards, all in a mainStack and 
a handful of substacks. I do feel, though, that the problem occurs when 
handlers in the mainStack are being worked on.
So I am fascinated; how would you even start? It isn't one handler that causes 
the problem. You would not even know how to use the thing, and therefore could 
not really put it through its paces.
I feel this would be a waste of your time, and though the offer is priceless, I 
have always felt that, in particular, your time is far more priceless.

Apparently I was mistaken.  When I read:

  "I must add that I am working mainly on a single project when this
    happens, and am conditioned to save often. The other projects I
    have currently do not exhibit this at all, though that may be
    simply due to the fact that I am involved in them much less
    intensely.
    I suppose it is less worrisome that this is a problem in only a
    single project, than if it happened here and there, everywhere.

...I got the impression that it was a problem in only one single 
project, less worrisome than if it happened in others.

Do you see a pattern to the crashes that might lead to a recipe?

Software is code. I already have the engine code.

I'm of the opinion that crashers are something that ideally should never 
happen in any scripting language.  So even if there's something we can 
change in your code to eliminate the crash, I'd still submit a bug 
report to see if a more graceful degradation is possible.

You're not obliged to accept the help.


 > In fact, none of those "outside LC" gadgets have ever caused a crash.

That may be useful diagnostic info.  What is an "'outside LC' gadget"?


 > The bugaboo is inside somewhere; I do not believe it is something I
 > wrote.

If you wrote nothing no crash would occur. :)

I'm not interested in seeking blame, only in seeking solutions.  And as 
I've said above, if there needs to a be any sort blaming we can always 
blame crashes on the engine.  So even if we find a workaround in which 
we change your script to stop the crash, that it resulted in a crash and 
not an error dialog implies an opportunity to further refine LC's 
exception handling.  And along the way you'd see the end to a 
long-standing crasher that's been interrupting your workflow.


 > Can I say "bugaboo" which is not a bug, but rather something that just
 > bugs me?

Sure, feel free to say anything you like.  But to me, any crash in any 
scripting language is a serious issue that merits further diagnosis.

If I can help diagnose this one I'd be happy to lend a hand.

Crashers are of course serious, but the good news is that you're only 
seeing it in one project.  Feel free to email me directly if you're in a 
position to allow me to review the errant code, and I'll see what we can 
do to both find a workaround to keep your progress moving along well,

Richard.
This happens all over the place, and seems to occur only after the stack has 
been fiddled with for a while. I cannot imagine that anything can be gleaned 
from the code base, which is 9000 lines of straight LC, with only a smattering 
of printing, printing to PDF, creating text files and reading and writing to 
them.
In fact, none of those "outside LC" gadgets have ever caused a crash. The 
bugaboo is inside somewhere; I do not believe it is something I wrote.
I have seen this in my other projects. They are not free of this issue. They 
just are not worked as hard,
Can I say "bugaboo" which is not a bug, but rather something that just bugs me?
I save often, and thereby save myself a lot of trouble.

Most of us share that concern.  To assess the issue soberly compels us 
to examine the nature and sources of reputation.

Reputation is only partly a reflection of actual technical fitness. The 
rest is a mix of factors that lie far outside of computer science, into 
the realms of psychology, sociology, and political science.

This thread is a good example:  What might have seemed at first like a 
bug in LC turned out to be a limitation inherent in the nature of PDF 
itself.

On the forums we see a another, with surprising frequency:  when the 
behavior of a script is not understood, the poster will sometimes 
surmise that the cause is somehow file format corruption. Many cases 
turn out to be just syntax errors, and IIRC few or none of those have 
turned out to be file format corruption.

We see a similar pattern with the documentation: many posts point to a 
need for additional information being added to the docs, with 
recommendations for learning basics linking to any of a wide range of 
resources spread out across the web, but on further examination we find 
that the fairly comprehensive 655-page User Guide included with the 
install hadn't yet been consulted at all.


None of this is to suggest that LiveCode is the world's first 
million-line code base that's completely bug-free.

But neither is it a roach motel when we consider the scope and 
complexity of the system with common metrics like bugs/kloc.


In the vast gulf between needlessly contentious allegations of 
"apologists" at one extreme and "Henny Pennys" on the other is a middle 
ground where meaningful product improvement can actually happen:

- Let questions be questions:  When an unexpected outcome is observed, 
we can keep an open mind about possible causes until the issue is 
diagnosed.  If we keep telling new users in advance that every 
unexpected outcome is a bug in LC they'll eventually believe it, even in 
the many cases where that isn't true.

- Let learning happen right in the box: We are blessed with a great many 
contributions from community members all across the web.  But to be 
clear, many of these predate the expanded documentation effort the team 
undertook several versions ago.  Moreover, those written after LC 
adopted an open source workflow missed the opportunity for greater 
readership, keeping them in a relatively small corner of the 
possibly-discoverable web rather than submitting them to the core docs 
every user is directed to right in the Help menu.  The docs are good, 
and can always be made even better.  We can help. Of course we want to 
see as much LC info everywhere, but core basics might just as well be in 
the box, and we do a good service to the learner to let them know when 
they already are.

- Let pre-release builds realize their value:  use them, whenever 
practical.  Putting off trying a new version until after Stable is the 
one choice that guarantees any issues affecting your specific work won't 
be fixed in that version.  We know from our own experiences and decades 
of industry literature that the earlier in the process bugs are 
identified, the less impact they have, and thus the total systemic cost 
to address them is much lower.


These are just suggestions, and certainly not any attempt at 
establishing any sort of "rules".  I have no authority to require anyone 
to do anything, nor would I even try, as I understand that from time to 
time there can be good reason to ignore each of these, and any other 

Re: text copied form LC generated PDF, WTF?

[dunbarx--- via use-livecode]

@Curry, mainly.
The easy one. WTF has lost most of its bite due to simple continued usage. As 
Lenny Bruce noted 60 years ago, if you use a bad word often enough, it loses 
its badness.
The hard one. Several threads on the forum have bemoaned what is labeled an 
overarching bug issue in LC. There have been calls for a complete halt to 
development until most of the existing ones are squashed. For my part, I only 
notice that LC 9x crashes intermittently, though regularly. I must add that I 
am working mainly on a single project when this happens, and am conditioned to 
save often. The other projects I have currently do not exhibit this at all, 
though that may be simply due to the fact that I am involved in them much less 
intensely.
I suppose it is less worrisome that this is a problem in only a single project, 
than if it happened here and there, everywhere. At least I tell myself that.
I am really only concerned that LC not get a reputation for being unstable. 
That would turn off new users long before they ever actually experienced such a 
thing.

 > Not to forget SpreadLib. ;)

Since you mention it, SpreadLib is not forgotten at all! Proud that 
SpreadLib was first, and is best, of its type. SpreadOut, especially, 
has come a long way since last public release. Looking forward very much 
to that update.

Most addons have progressed with features and fixes privately, and are 
waiting for official release, but releases take some time in themselves, 
and client deadlines always have to come first. We have some clients 
here that could vouch for both parts of that statement. :)

(I'm physically handicapped with some taxing health limitations, thus my 
active time is finite, determined by actual daily energy/strength and 
endurance, without anywhere near as much choice or freedom over my 
remaining time as most people take for granted. So clients get heavy 
priority, but addons are never forgotten and the work continues. Nor is 
this list ever forgotten, although I can't afford to be very vocal here 
beyond the occasional quick joke or brief comment. Mostly I'm a reader! 
Not by choice.)

LC's "infinite bugs" increasing in tempo since LC7 and frequent breaking 
changes have outpaced me at times, providing an ever-shifting foundation 
for building upon. Breaking things is usually easier and faster than 
cleaning up. In fact, I've devoted an amazing amount of my entire career 
to finding, documenting, and developing high-quality workarounds for 
these IDE and engine bugs - and it seems that we're just getting started.

But here's the good news - I'm adjusting strategies and tactics to that 
reality, having finally accepted it as the norm to expect now and 
perhaps forever. So I'm also developing new tools to gain the upper hand 
again in this Age of IDE Bugs, and therefore confident that I will 
indeed have the last laugh on this subject of my delayed progress (ha 
ha) and get addon updates back on a much more regular schedule, among 
other things that are likely to cause a big splash - perhaps even shake 
up the industry a bit! :D

Another high priority for update release this year is WordReport - quite 
a lot of inquiries lately, which are pushing it toward the top of my 
list. Yep, it's coming, and it's going to reach new heights. Thanks to 
all for your feedback and support! Exciting things are on the way.

--

About the subject of copying and pasting to/from LC, here's a current 
bug that's easy to workaround, but also easy to forget to workaround - 
and can cause mayhem:

https://quality.livecode.com/show_bug.cgi?id=22172

--

BTW, it's a tad difficult to completely ignore "WTF" posts, and my post 
here was a joke on two levels, the first of which Klaus immediately 
acknowledged.

But the second level had a more serious undercurrent, and it's why I 
posted a reply in the first place: is WTF considered completely 
squeaky-clean and shock-free nowadays? Has it, along with its component 
words, been completely sanitized for all ages and audiences? And if so, 
then logically: why unfailingly abbreviate, without ever using the 
component words every now and then for variety, and also why not use 
something a little more risque and exciting than a plain-old 
unprovocative WTF? :)

Thus the WTF file format, since it is so often mentioned here lately.

Take care and enjoy coding, everyone

Re: the fontnames and special names like (Menu)

Here is some unhelpful information from the dictionary:
The list of font names includes a set of special-purpose names which 
automatically select the matching font for the platform. You can use these to 
request "the font used for buttons" without having to hard-code 
platform-specific font names. These fonts are:   
   - (Text) - the font used for fields and other controls with editable content 
   - (Menu) - the font used for menu items
   - (Message) - the font used for buttons, labels and other communication from 
the app
   - (Styled Text) - the font used by default for rich text
   - (System) - the font for controls not covered by another category
   - (Tooltip) - the font used for displaying tooltips
   - (Default) - selects one of the UI fonts automatically based on the control

The fontnames() function returns certain special font names like:

(Styled Text)
(Menu)
(Text)
(Message)
(Tooltip)
(System)

How do I find out what fonts these really are on a given platform. The 
effective textFont does not seem to work.

For example the following code on Windows 10,

set the textFont of fld 1 to "(Text)"
put the effective textFont of fld 1

outputs "(Text)" when I would have expected it to output "Segoe UI"

Is this a bug?

Re: Automating User Input

[dunbarx--- via use-livecode]

Bob may have much of what you are asking for.
Many years ago I made a form filling stack. The user clicked on various 
controls an/or images, and either a popup of available options or a dialog 
appeared. It worked as if each image, say, was its own popUp. Once the 
selection was made, the user was brought to the next step. If that step 
sequence was not hard-coded, it was left to the user to select that next step.
Not sure about your UI, but this sort of thing is simple to implement in LC.

Is this going to be strictly an LC app or are you going to try and use the 
browser in LC? I have functions that "remember" things typed into a field, and 
auto-complete based on what the user types. The weakness is of course that if 
you have words that are very similar, especially at the beginning, you would 
need to type a lot before you ever got to the unique word you were looking for. 

I can modify the script so that hitting the right or left (up or down??) arrows 
will cycle through the matches.

Hi all. 

I n a tab button on a Mac, for some reason in the IDE, the text of the first 
tab is green and subsequent tabs are red. In a standalone, the text of the 
first button is YELLOW! No colors or effects are applied. 

Obviously not a show stopper, but people are asking me what the significance 
is. I have not found a property where I could change that (which might actually 
be cool!)

Using text only script behavior files has advantages and disadvantages. One

 Your app could easily become like some horrendous-humongous PHP or JS 
framework with 100's of "dependencies."

behavior_Story.livecodescript     
    # which is assigned to the stack, handled the UI/UX for stack

This approach requires a lot "Switch cases" as you may be targeting the UI/UX 
of many different groups  on the card or different cards. 

So far I am happy that I am having to  debug  just two scripts to manage 
"everything" 

But I have question on "closeControl" for which there may be many groups on a

is it "Switchable?"  and can we use it in a single behavior that "looks at"

We might as well use "on closeCard"

Hi.
"SetControl" doesn't take a parameter, as far as I know, so a switch control 
structure would have to be managed by hand, perhaps looping through all the 
groups (or other controls of interest) on the card that one just navigated away 
from.

Re: LiveCode won't recognize my stack

Hi.

I have two monitors as well. And I use a key combination and a plug-in to
reset the loc of the very stacks you mentioned, plus the SE. These change
each time I save a stack. 

The point being that I never have a problem saving, only that I have to
reset the loc of the topStack and the others each time I do.

More than worth it to have two monitors, though.

This is most likely because you haven't got the stackFiles property set 
up, or the defaultFolder is not what you are expecting it to be - i.e. 
the engine cannot find the stack with filename "LicenseKey.IW" relative 
to the current folder.

The IDE still uses the form of 'answer file' which specifies a 
creator/filetype and an extension. I suspect either one of:

  A) the creator/filetype is actually recognised by more recent versions 
of macOS (i.e. they are ignored completely - I don't recall a report 
against Mojave, but it is entirely possible Catalina no longer supports 
them)

  B) The file has just lost its creator/filetype and thus is being 
filtered out (this can happen if a file is archived via a format which 
doesn't support these attributes, or has transmitted through an FS which 
doesn't).

Use All Files and select it that way, as you have been doing :)

9.6 dp1, in the message path different independent groups are not encapsulated.

button "starWidget"
-- has no script
-- is not a part of any group

Stack script:

on mouseup
          put the short name of the target
          put the short name of the target into tTarget
          switch tTarget
                  case(s) # various button names

          end switch
end mouseup

# the card are several groups,
# each with its own mouse handlers

# I click on button "starWidget"
-- nothing happens…hmm, no errors either…
# start profiling scripts (new trick I found)
# click on button "starWidget"
# stop profiling scripts:
          # Voila! the mouseup was trapped by one the other groups, as if they 
were in the message path.

Is there any way around this? Meanwhile I have to plug into every button 
explicit handlers. Tedious, make debugging painful…

Re: Achilles Heel of Livecode

I used Compile-it forever. It was faster than the compiled v.2x HC by orders of 
magnitude.
But, and this is hardly a fair test, I get over 8 million passes per second

The point is, how much more speed can be garnered if a new complier was

Remember Compile-It for Hypercard?  Perhaps
we need something similar for LiveCode that
would run at standalone creation time, or
whenever we request it for that extra-speed.

I know the system took a big hit with Unicode,
so how about the option to turn it off for programs
requiring super speed?

Just my 2 cents.  :-)

Re: How do I select graphics that are on top of each other with mousedown?

[dunbarx--- via use-livecode]

The "mouseControl" is very straightforward. The "target" would work just as 
well. In the card script:
on mouseUp  answer the targetend mouseUp

But for a line graphic, you must click right on the line, or the function will 
not work. In other words, the extent of each graphic is the same, but only the 
lines themselves will respond.This solves the problem discussed below, sort of.
Grouping them will not help.
This harkens back to just the opposite problem, discussed a couple of years 
ago, where it was desired that a click somewhere within the "extent" of the 
graphic would trigger an event.

Re: Identifying Un-used functions and commands

Jacque,
Ah. You may be right.
So, Steve, which way, or do you need both? The methodology is basically the 
same.

I think he wants it the other way around, identifying handlers and 
functions that aren't called by any other handler. I've done this, but only 
one at a time, by searching for the handler name across all open stacks. If 
the only occurrence is the handler itself ("on/function whatever", ) then 
it's unused.

The method here would probably be to get a list of all handlers and 
functions and then do a global search for instances of each. If there's one 
or more that isn't the handler declaration, it's used.

Re: Identifying Un-used functions and commands

[dunbarx--- via use-livecode]

Hi.
This was posted a couple of weeks ago, no?
I suggested then that you could write a short handler that loops through all 
the scripts in all the controls on all the cards, and isolate words that are 
not preceded by either "command", "on" or "function". In this way you might 
see, for example, that "myGadget3" may be present in scripts here and there, 
but there is no "on myGadget3" anywhere. Then you will have found an unused 
handler call.
This may require tweaking. For example, LC will compile, say:
"on         myGadget3"  -- spaces galore

Since there is code in the script editor that knows the location of any command

well on your way to developing a way to grok it. Also, GLX2 has a 
"clairvoyance" (Auto-Complete) function that is handler aware. I suspect Mark 
Wieder developed a method for getting a list of all handlers in a stack that is

Re: remove DEFAULTMENUBAR?

[dunbarx--- via use-livecode]

Hi Klaus. 

I never have worked at all with this group, and was surprised that it was a LC 
stack in the first place. 

So I do not know why one cannot set it to empty, except maybe that something 
inside LC prevents that. 

On a completely tangential note, my defaultMenubar contains ten buttons, the 
first one being button "File", and the last one (after button "help") being 
button "divider". No idea where that button is, or what it does.

Re: Y coordinate for a line of text

[dunbarx--- via use-livecode]

I misStated this completely. The point being that no property of the field 
itself should be a factor at all, not its loc or rect, for example. Only the Y 
value of the selectedLine is pertinent.
Glad you have what you need, but I still do not see the value of the 
selectedLoc. This depends on the loc of the field, and otherwise has no 
relationship to the field itself, that is, the Y coordinate within that field.

Re: Identifying Un-used functions and commands

[dunbarx--- via use-livecode]

Hi.
"unused functions and commands"?
Do you mean handlers that exist in a script somewhere but are never called from 
anywhere?
I suppose you can search all scripts, and if a certain handler name does not 
appear without being prepended by either "on" & space(s) or "function" & 
space(s) then you can say that handler is never called.

Re: Learning from scratch - any recommendations?

I am with Richmond, mainly.
I hate to learn another language. That is why I live in the United States.
LC, if you introduce only a  handful or three of native words, controls and 
concepts, is accessible to anyone with a real desire to learn this sort of 
thing. Even a first grader; they just need more mentoring. Even someone who did 
not know they would like to build stuff in software.
The trick is the engagement, to make it seem cool and fun.

I have a radical disagreement with Scratch and its ilk as, while it does
allow one to run up simple computer games, it does not let users see the
"guts" of a program, and seems not to give children transferrable skill for
non-block programming languages. I have successfully started kids from 9
years old and upward on programming with both BBC BASIC and Livecode.

Now I see what you see. I cannot be sure I did not mess up the procedure

It is possible you have not placed a blinking cursor into the inspector field?

That works here as advertized, no formatted text after using the shortcut or 
menu!
Problem, the text does not get into the field on the card!

And when I switch back to the "stacled text" tab of the inspector, the pasted 
text is also gone!?
Too funky!?

Re: Learning from scratch - any recommendations?

[dunbarx--- via use-livecode]

Hi.
I have taught several newbies. I always start with a simple app, like an 
address book. I show how controls are created, and how scripts are built. 
During that process, I am off in the weeds, writing short handlers showing how 
the cursor can trigger things like mouseEnter or mouseMove, these messages 
having nothing to do with the task at hand, but  rather similar to what we are 
working on.
This is all way before the message hierarchy or anything intermediate like 
that. The point is to get them hooked, and that can only happen if the basic 
simple things appear accessible and comfortable. If you are good at this, it 
will also appear to be fun.

Subject: Learning from scratch - any recommendations?

Hi all

I have been approached by one of my family to ask what would be the first steps 
for someone (a young adult) to enable them to enter the world of app design and 
programming. Obviously I need to ask more questions myself, such as whether 
this would be to get a job, or simply as an educational exercise, or maybe to 
provide a launchpad for a startup idea. However, even at this stage, of course 
my thoughts turned to LiveCode.

So my question to the community is, how would such a person start off - 
assuming they’re intelligent, very familiar with consumer-level technology such 
as smart phones, tablets, laptop computers for study etc. and social media, but 
probably have never seen or thought about what is involved in designing, 
implementing and publishing an app (I would just say “a program”, but that 
shows how old I am) on any platform? If it is LC (and why not?), are the 
published lessons sufficient? What is the view of those on this list who do 
actually teach this stuff? 

The trouble for me is that I have been around all this for 50 years (more, to 
be truthful) and so can’t project myself well into the mind of that kind of 
newbie. One guess is that one way to start would be to find a cheap hardware 
platform (probably an Android tablet) and try to use the LC Community Edition 
to allow me to create something for that; but that idea may be stupid, 
particularly as one would need a different platform to actually do the 
development work.

Hoping for some insights

Graham

Re: Red Dot Breakpoint Crashes

[dunbarx--- via use-livecode]

Just an aside.
I never experienced a "crash" of any kind with a red dot. I only found that, 
after editing a script with a dot in place, it had become disabled as if it was 
not there at all, and execution proceeded right past it. If I deleted it and 
put it back, it worked fine again. But that hardly recommends the original dot.

it might start off printing say 14 reports per minute after a few minutes it's

Re: Push Card

[dunbarx--- via use-livecode]

I still maintain a HC server stack, accessible by clients over a network, of 
many thousands of cards. Access to any of them using the "find" command is 
virtually instantaneous.
It is LC that starts to visibly slow after about 2000 cards. Someone like 
Richard or Jacque may know a bit about why that is, but I assume that LC simply 
carries much more baggage.
It must be remembered that HC was designed to run on a 1MB Mac. Color was out 
of the question, and the routines for finding stuff was considered 
revolutionary and was carefully guarded.

Subject: Re: Push Card

Hi Andrew,

I think the problem is having very many cards—in the thousands, each with text, 
images, etc.—that I experience slowdowns. The stack taking a long time to open, 
save, go to cards, and just wanting to freeze for awhile.

When I changed my method to just a few cards with the text and the data used to 
display it stored in arrays, page loading is lighting fast. Creating fields and 
buttons, formatting them and filling with text on the fly, then deleting them 
when I load the next “page" is really fast. I put images on a web server that I 
pre-download to memory so they display quickly when needed is also part of the 
plan. These images could otherwise be stored as files on disk, or in a LC 
stack. Images in a LC stack can be referenced by using a button and setting its 
icon to ID of the stored image.

Using these kinds of techniques I went from a 600 MB collection of stacks down 
60 MB— 1/3 text and other data, 1/3 images used as thumbnail images embedded in 
text fields, and 1/3 the LC engine runtime, and I moved several hundred MB of 
images to the server.

LC is really fast with small stacks, and it’s really convenient just to lay out 
bunches of cards with stuff, but after  awhile, LC just isn’t fast anymore.

Re: Push Card

[dunbarx--- via use-livecode]

This goes back to 1987. The HC team assumed that most people would navigate
like crazy, think rolodex, and being able to retrace ones history would be a
very useful tool.

There should be a "clear recent" command, so that the piles of cards in that
history can be eliminated. But LC has things that make this simple, the
"recentCards" and "recentNames" properties.

Re: Button scripts

[dunbarx--- via use-livecode]

Hi.
The "target" tells LC which control received a message. If you had a script in 
the card, something like:
on mouseUp
set the bordercolor of the Target to "orange"
set the showBorder of the target to "true"
--- do somethingend mouseUp
You would not only have quotes in places you ought to, but need only that one 
handler in your stack.
Note that oftentimes you do not want EVERY button to react that way. There are 
two ways around that.
1- Trap "mouseUp" in the offending button.2- Set a property of some sort in 
those buttons, such that (pseudo):
on mouseUp
if the name of the target has some nice property thenset the bordercolor of the 
Target to "orange"...

Substacks are below (Hi, Jacque) the mainStack which own them in the message
hierarchy. Try this:

Make a new stack, name it "Main1". Make a sub stack of that stack, and name
it "Sub1". Put this into the script of the main stack:

on mouseUp
  answer "Main" && random(99)
end mouseUp

Now put this into the script of the subStack:

on mouseUp
  answer "Sub" && random(99)
  -- pass mouseDown
end mouseUp

If you click in the mainStack, you will get "Main...". If you click in the
subStack, you will get "Sub..." If you uncomment the "pass" statement in the
subStack, and click in the subStack, you will get both.

So like any object in the hierarchy, you have to manage your messages.

Re: Stacks and Sub Stacks

[dunbarx--- via use-livecode]

Hi.
You probably mean script-only stacks.
Substacks are just stacks, but they live in the same file as the mainStack. It 
helps with organization, and when you save one, you save them all. You can only 
have one mainStack, but as many subStacks as you like.
For me, I have projects that use substacks for, say, data entry. The subStack 
is built just for that purpose.
When making a standalone, substacks are included in the final package.
Just practice a bit.

When I copy-paste an image from one card to the next with the menu and a

when I copy-paste with CMD-C, CMD-P the resultant image is a solid black

Re: Help with an algorithm...

[dunbarx--- via use-livecode]

Hi.
This seems like a good case for arrays (pseudo):
You have to create an array for each parent. The only way i see to find those 
is to go through the list looking for lines that DO NOT start with a space. If 
you work from the bottom up, since children are always at the bottom and they 
always have spaces in front, you can find the lastMost parent.
Set the itemDel to that parent, and isolate the last item. This will be a list 
of children of that parent.
See if there is a corresponding parent in the new list, and isolate that "item" 
list of children.
Run through the children of the old list and see if they live in the new list. 
If they do, add them:The array part is something like:
put oldChildren & return & newChildren into allChildrenrepeat for each line 
tLine in allChildrenput tLine into myArray[tLine]

Delete the last item of the old list and do it again. This way the last item 
can be isolated directly.

Today is not my coding day. I have a problem I should be able to design 
a solution for an am struggling. Clearly I am missing "something"

I have 2 lists (LISTNEW and LISTOLD) of the following format:

ParentA
Child 1
Child 2
etc.
ParentB
Child 1
etc.
etc.

The parents are in alphabetical sorted order, the children may not be in 
sorted order

I need to hunt through LISTOLD comparing the LISTOLD Parents to the 
LISTNEW Parents
   FOR any LISTOLD Parent present in LISTNEW, check the Children of the 
matching Parents and add any Child for the LISTOLD Parent that is not 
already under its matching LISTNEW Parent
   FOR any LISTOLD Parent NOT in LISTNEW, I can ignore the Parent and 
its Children

I can not seem to write an approach to solve this today. Does any body 
have some code so solve this they may be willing to share?

Re: Draw a line that follows an object

A million ways to escape. One could substitute this for the optionKey the line:
if the mouse  is down then...end if
That assumes that the drawing is always done with the mouse held down. Not sure 
about that. And since "send in time" releases control to the machine 
constantly, one could add an escape handler downStream triggered by just about 
anything.
Much depends on the way the author wants this thing to work.

Re: Groups do not receive mouseEnter messages?

[dunbarx--- via use-livecode]

Confirmed here.
I have never really tried any of the things you mentioned, but no messages at 
all are sent to the group I just made.  Interestingly, and consistent so far, 
double clicking within the group boundary, but not in any child control, opens 
the inspector for the card.
So although the dictionary talks about many properties of groups, and states 
that it is a control in its own right, it does not seem to have much body 
outside of its children. This even though one can make the group red as a beet. 
The "object" certainly exists, and has a multitude of properties. It just 
doesn't seem to be quite there.

Subject: Groups do not receive mouseEnter messages?

In LC9.0.5rc1 under Windows, I have a test stack with 2 opaque groups 
with show borders  - one covering the top half of the card and one 
covering the bottom half of the card. In side the top group are a couple 
buttons with plenty of white space around them and inside the bottom 
group are a couple of graphic objects with plenty of white space around 
them.

The buttons and graphics have no scripts (currently). Each group has an 
"on mouseEnter" handler that "choose browse tool" for the top group and 
"choose pointer tool" for the bottom group.  The simple idea being when 
the user moves the mouse into the bottom group, the pointer tool is 
chosen so they could click on and resize the graphics. And when the 
mouse enter the top group, the browse tool is chosen so the user can 
click on the buttons without selecting them.

Neither group seems to receive the mouseEnter messages. Instead, the 
groups mouseEnter handler is executed for the top group only when the 
mouse is moved over one of the buttons (which has no mouseEnter handler 
and so the message is passed to the group) and likewise, the bottom 
groups mouseEnter handler is executed only when the mouse is moved over 
one of the graphics.

Do GROUPs not receive mouseEnter directly? This seems like a bug?Or is 
there some trick (property settings) for a group to receive mouseEnter 
messages?

Re: Help with drawing in LiveCode...

Again, my drawing gadget creates, sizes, places and dimensions graphics, 
simulating a CAD drawing.
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.

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: Help with drawing in LiveCode...

[dunbarx--- via use-livecode]

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 
than, say, AutoCad or SoldWorks would produce.
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.

Hi.

The "screenMouseLoc" is a property, but the "mouseLoc" is a function.You

Why this was wrought this way is anybody's guess. I recommend that you make
a library gadget that automatically takes the open LC window properties and
does the math. Then your "newMouseLoc" property can be local to the window.

Re: Live search box

[dunbarx via use-livecode]

Hi.

When you change an ordinary property, you set it to a new value:

set the width of btn 3 to 50.

A custom property is "filled" in the same way:

set the rawText of me to chapterOneOfDonQuixote

Custom properties are created just like variables; you just do it. Try this.
make a new button named "XYZ", and:

set the albertEinstein of btn "XYZ" to "E=MC^2"

Now go into the property inspector and look at the custom property pane. Or
you can always:

answer the albertEinstein of btn "XYZ".

Custom properties can hold any value of any kind of any size. They survive
sessions, unlike global variables, and do not have to be declared.

Go practice.

Hi.

This is fun to do. Make two fields. In the target field, the one you will
type into, set a custom property "rawText" to some long list of words,
perhaps chapter 1 of your favorite novel. It is a good idea to strip all
punctation from that text before setting the prop.

In that field, place this handler:

on keyDown tKey
   if the length of me > 2 then put line lineOffset(me,the rawText of me) of
the rawText of me into fld 2
   pass keydown
end keyDown

Re: Splitting long elements into two lines in an Option Menu

[dunbarx via use-livecode]

Hi.

If I were you, with the task you laid out, I would not use an option menu.
It is not good with wide menuItems, and it is not natural, if even possible,
to select multiple lines in the way you want.

Use a list field instead. A field has many properties that are denied an
optionMenu, which is really just a button.

You can have multiple lines selected, by trapping "mouseUp", say, and with
the clickLine, select the following line as well. Or the following five. Or
the previous. That sort of thing. A field just is far more able in this
regard.

You do get all three buttons enabled. But the thinking is likely along the
lines of: "That guy enabled the group, right? That means enable the group, 
which includes all its member controls, right?"

Or something like that.

I think this has merit, and I would just set a custom property to restore
the disabled controls.

Re: Enable/disable Group enables/disables all children

[dunbarx via use-livecode]

Does it make it more palatable to think about it the other way around? There
should be no real difference:

You have a group where one button is already enabled, and one already
disabled.

By disabling the group, should the enabled button stay enabled?

i would say this is expected behavior.

If you disable a control in a group, and then enable the group, LC assumes
you want to, er, enable the group, and that means all members of that group.

So as you mentioned, make a gadget that stores the states of all the
members, and resets when the group is enabled.

There must be something different in our setups. All I did was write a 
rawkeyUp handler to return the value of my mouse's right-click. Either you 
get a different value with that action, or something in your machine is 
intercepting that "message" before LC does. 

This was a while ago, so I had forgotten. (No "oops" emoticon in the
use-list) I have a configurable mouse, and set the right-click to simulate
"F4". Jacque uses, I think, something like "Cmd-Tab", which is similar to
how we used to toggle tools in HC. I did something like that for a while,
until I changed to using my mouse.
