Re: [OT] EULA and legality

[Ken Corey]

We all know companies make the T's & C's to suit themselves as much as 
possible, giving as little as possible while gaining as much as possible.


I feel that EULAs, copyright and patent laws have gone well beyond too 
far. They have gone so far that corporations are far more important than 
people, than facts, than truth (not capitalised).  Their lawyers rewrite 
history, twist laws, and jeopardise markets.


They are morally indefensible in this day where we must use technology 
to get things done.


Personally, I don't pay too awful much attention to EULAs. I prefer 
common sense. Personal use, don't destroy other's businesses.  I do wish 
others felt the same way.


The thing that worries me the most here is that when every new medium 
came along (printed sheet music, player pianos, radio, TV, cassette 
tapes, fax machines, telephones, computers, internet) the entrenched 
media moguls have railed against the tech, and tried to protect their world.


Every time before this, they've been utterly defeated by reality and 
common sense.


This time, I'm afraid they're winning.  Closed shops, licensed software, 
UEFI limited hardware, hardware you can't open, copyright extended 
beyond all reason, IP used as a weapon of business.


Pretty soon we'll all have to pay Apple royalty for breathing iAir.

Feh.

I think the only thing keeping the corporates honest is Linux in all its 
forms.  Without Linux, there'd be no Android and Apple would well and 
truly own the tech world. *shiver*


Once Linux is killed off, I'm going to start growing turnips.

property contained within the book is,
 generally, restricted by copyright saying whether I can copy bits
of it, resell it, lend it to friends,
 lend it while charging a fee for its use, and so on. However, the
copyright restrictions do not tell me
 where I can read the book (in the bath?) or how (standing on my
head?).

2. I am running Mac Snow Leopard in VMplayer on Non-Apple hardware.

Before I continue, I should point out that as I own a physical install
disk for Mac OS Snow Leopard
I don't feel MORALLY wrong running the software it contains in VMplayer.
I am running software I own
in one instance and do not feel that because I bought Ferrari hubcaps
for my Lada I should be forced
to buy a Ferrari.

3. Other people on the Use-List must face similar questions.

4. I really wonder if this belongs in the same category as the previous
set of postings about
 software piracy - I don't feel it does.

A. How legally binding is a EULA?

B. I have connected to Apple via software upgrade, so, one assumes, they
are well aware that at
 least one person "out there" is violating the EULA.

C. Anybody can purchase software online or in a shop without background
checks to see whether
 one has the necessary hardware to keep to the EULA.

Of course this can extend to Livecode, and all the products we folk are
doing our best to produce
with it.

There are also some 'funny' rumours flying about that Microsoft are
doing some deals with PC makers that will lock the machines in some way
so that they will only function with Microsoft Operating Systems, rather
than Linux, UNIX, Haiku and so on.

Re: pirate version of my book...

I have always had an inkling that the best way to beat piracy is
1) to give users a reason to keep contacting you (regularly upgraded 
content/capabilities).

2) making it /easy/, even automatic in your app, to contact you.

Both of which Runrev has gotten fairly right, at least for those of us 
on the dev track.


I wonder if that's why you didn't find bootleg copies out there?

Re: pirate version of my book...

Real numbers will be hard to come by obviously, but androidpit seems to 
claim that they provide for those in eastern europe and russia (and 
maybe down into the far east for all I know), as they claim to have set 
up deals with merchant providers in those countries.


Android pit seem to be working all the angles.  You must deposit money 
with them (in multiples of $5, I think), and purchase out of those 
funds...so there's a tidy profit in the tied-up funds sitting in their 
account.


Incidentally, the app we released was on sale for $199.99, the max the 
Google play store will accept in the US. On AndroidPit it was available 
for $239.99.  As if they needed even /more/ markup!?!


Then, you must install an androidpit installer app, setting your device 
to allow apps from unknown sources.


So, it's illegal there, and it's /easier/ and *cheaper* on Google Play.

I guess that I'm saying they probably aren't taking a huge bite out of 
most people's earnings.


Gads, I *hope* people aren't stupid enough to buy from them, at least in 
the markets Google Play inhabits.

Yep.

Two days after releasing my app on the Google Play store, it showed up

It's possible to port libcurl to android:

Why version 4.0 specifically?  Why not version 3.0, or 2.0, or 5.0?


I used the word 'say'.

I would like it if Runrev offered all previous whole-number versions

that NO SUPPORT is offered


Offered or not people who pay expect (with some justification) to be 
supported.


There's the unwritten implication that version 2.0 is just as good as it 
ever was.


That's true if running on Windows XP SP1 or OSX 10.1, but as these 
operating systems have changed I'd expect things to break.  Therefore, 
releasing old solid number versions would start to consume resources again.


Remember GOG.com?  "Good Old Games"?  They didn't just let you download 
the bits of old games, they rereleased them, suggesting at a minimum 
recompiling, but likely testing and the whole lot again.



It would bring RunRev some modest revenue from people who have neither
the money to invest in the latest version, nor the requirements to have it.


I disagree.  While it might bring in money, you'd have to work to 
convince me that there'd be enough revenue to pay for itself, while also 
reducing the numbers of people that pay for the new versions of the 
software.


But, I'm humble enough to admit I can be (and am often) wrong.

Why not propose to runrev that you'll finance the release of older 
versions of software?  If it's a money spinner, you'll do okay out of 
it, and runrev won't have the support issues for old versions of the 
software?

Re: LC Android FC on Samsung s 3 sph-l 710. Android version 4.0.4

[Ken Corey]

FWIW, the same behaviour I saw before. (Samsung Galaxy Tab 2 10", 4.0.4 
stock, with the default Samsung keyboard.)


When predictive text is on, no text entered shows in the text entry 
widget.  Turn off predictive text, and you're off and running.


Just as a data point, I installed SwiftKey 3 and tried that.  No 
problems at all.


I had logcat going the whole time, and again, didn't see anything untoward.

I went through selecting one of the rows returned, and the map was 
pulled up, as well as trying to add the phone number to my contact list 
(since it couldn't be called on the tab).


Not an in-depth testing session, but it certainly would have thrown up a 
problem if it were going to.


Just for grins, I tried it on my Nexus 7 running Jelly bean.  Sure 
enough, it crashes upon launch, so I can't tell if the input would hvae 
worked there.


Best of luck.

I don't have that device either.  I was going to try it on my Samsung 
Galaxy Tab 2 10", but the app wasn't available for my tablet.


So, I made a new stack, dragged a text entry widget onto it, and 
launched it on the tablet.


I only have the Samsung keyboard installed.

When predictive text is on, the word never appears in the input.

With predictive text off, the text appears as expected.

No FC here, but not acceptable behaviour either.

I was watching logcat, and didn't see anything immediately obvious there.

I'm not given the option of going back to a google keyboard on this 
device, so I can't provide any more info...sorry.

Oh, the program demonstrably functioned, but if it did not meet with

the design goals.


So it would seem that the initial design,coding and delivery is no more 
than half the ideal process.  There needs to be a feedback loop where 
the user interaction is observed, quantified, and learned from to 
improve the app.

Re: The Screen Density Conundrum

[Ken Corey]

I'll vote for scaling upon first load.

We've forgotten something here. When we get away from being tied to 
pixels, we can give our users more choice.


My 72 year old father will want the chrome of an application (as well as 
the content) visually much larger on the screen (pixel density and 
screen size notwithstanding) than I would...and my 9 year old son, with 
incredibly sharp eyes, can make out the pixels on a retina screen.


So, conceptually speaking here, we'd need to add a parameter to the end:

objSize = ((orgObjSize * screenSize)/pixelDensity) * userPreferredSize

As I have started using reading glasses, and my eyes get worse, this 
will become ever more of an issue, I suspect.

Re: Is it really this hard to print currency values?

[Ken Corey]

It's actually stickier than that, depending on how far and wide your 
currency must be displayed...


Currency can be 1-3 characters ($ or GBP, if you see what I mean)...and 
many of the single letter currency symbols require unicode...take the 
euro "€" for example.  On windows it's alt-0128 (on the keypad).


The thousands separator is '.' in the US, but it's ',' in many parts of 
the world (Europe).


The decimal separator seems to always be the opposite of the thousands 
separator (if the TS is ',', then the decimal is '.').


And how is it formatted if the number goes negative?  (1234.00)?  -1234.56?

I'd probably try something regexpy here...let's see...

Anyway, if you're talking just the US, how about:

put 12345.67 into q
put "" into retval

Re: Old timey data entry GUI problem

[Ken Corey]

I'm not sure what kind of tourney you've got there, but why in heaven's 
name do all 4 numbers have to be entered each time?


Surely the id is known before-hand...and likely the table and partner 
number too, otherwise how is this event scheduled?  All of this should 
be entered before the event happens, I'd have thought.


So really, the only thing that needs to be entered is the points.

Now I'm just thinking out loud here...but what's your point range? Is 
there a limited number of points that could be scored? Is there a chance 
this could be done on a slider?  Even if not, a single entry is not as 
painful as entering 4 numbers.


Further, why does it have to be a page per entry?  Why not a table 
format so that the data entry person doesn't have to leave a page?


Finally, with a table format I'd forgo the mouse altogether.  When the 
data entry person presses  in any of the fields, that row of the 
table could be submitted or stored.


The bigger question in my mind though is how are all these tallied at 
the end?  4 people entering numbers means 4 computers, perhaps all 
reporting the results to a web server? Do the numbers need to be 
communicated between computers so that the data entry person on computer 
1 see what is entered on computer 2?


How were you thinking of tackling the data gathering once entered?

I know it's sacriledge to say so here, but what about the data entry 
people each entering the scores into an excel spreadsheet, and then the 
4 spreadsheets be joined at a single computer?  Lower tech than a 
custom-written solution, but all data entry folks know how to run Excel, 
and how to copy/paste from 4 sheets into one.

Hi everyone



Sorry for the wall of text, here's a short version:

I am developing a software for a charity tourney. I need typists to enter 4 
numbers about 200 times within 30 minutes (or so). See screenshot of what I got 
right now: http://i.imgur.com/G7Fgg.png

I have no experience with such a situation at all. My question is: How can I 
enable the typists to be very quick, but also make sure that they won't 
accidentally submit a false or partial entry to the database?



Much more details:

There's about 200 players in the tourney, and rounds are between 30 and 45 
minutes. Each of the player hands in a slip of paper as a tally after each 
round. Four numbers from these slips should then be entered into a database by 
typists. People cost money, so the less typists needed, the better. That means 
the form has to be geared towards fast data entry, because they need to finish 
in time for when the next round ends and new slips start to come in.

In my current GUI, I have four fields, with some restrictions and so on. After the fields 
have been filled out, the typists have to press a "Save" button with the mouse. 
The problem with this is of course that changing a hand from the keyboard to the mouse is 
just generally slow.

Some thoughts about how to approach this more efficiently:

- Use the enter key on the numpad, but only when in the last field.
--   I fear this could lead to some accidental entries.

- Use enter key and pop up a dialog, so that the enter key has to be pressed 
twice...
--   People would probably start to always hit twice automatically, making 
the entry take longer with no benefit.
--   But then, dialogs in LC can take variable time to pop up, making

- Force them to press shift (or other key) and return at the same time.
--   "Smart" users could start to hold shift down all the time, because 
that is easier.

- On a different note, maybe have a second person reads the numbers to a typist?
--   I feel that would make error checking after the entry too hard.
--   Several reader/typist pairs would confuse each other.




I know that some of you guys worked with data entry for decades, and that text 
only interfaces used to be all the rave. So I'm sure there are best practices, 
or often used approaches for something like this?

Thank you for reading
Björnke

Re: The future of LiveCode

[Ken Corey]

I've already gone on too long, so apologies to all.

But, it seems to me there's a manpower shortage.  There's lots of work, 
and not enough engineers/coders/documentors/etc to meet it.


What about volunteers?  I'd /happily/ code up solutions to my troubles 
(no header access for http calls on mobile, I'm looking at you) if I had 
access to the source code.  I wouldn't need access to the lot either, 
just enough of a test harness to develop the code.


I'd sign a non-disclosure, and waive all rights to the code submission, 
if I were granted next year's licensing fees paid.


That is, of course, only when the code is accepted by runrev as being of 
high-enough quality to meet RunRev's needs, so there'd be little risk on 
their part.


I figure I've got enough C experience on many platforms to be able to 
make that kind of contribution.


For other folks, perhaps documentation is their thing, or helping to 
code more tutorials is more appropriate.


I respect Runrev and Co, and submit that their jobs do need to be 
protected...  I'm not suggesting open-sourcing the lot...but there's an 
amazing amount of latent talent in the folks on this mailing list.  I'm 
surprised more of them aren't being tapped to work on choice morsels.

Re: The future of LiveCode

[Ken Corey]

The problem I had when I was starting LiveCode is that the information 
is scattered all over here and there.


I was interested in LiveCode for mobile development.  I started with the 
User Guide.


I wanted to create a button on the screen.  Okay, so create a new Main 
stack, drag the button out, drop it on the stack, boy this is /easy/!


Let's try a few things on the desktop.  Man, piece of cake!  Now, let's 
try it on the iPhone.


Oh..uh..I have to configure the standalone settings.  Where's that 
documented?  Not the User Guide.  I searched high and low before someone 
suggested the iOS release notes.


Well, that's helpful. Okay, start digging around there. Oh, in 5.5.1, my 
iOS Release Notes are greyed out.  hrm.


Try the dictionary.  Well, that helps me learn about buttons, but isn't 
much good for standalones.


Hrm, Okay, ask a question on the forums.  Well, that is hit or miss. 
Just play with the form until I get something working.  Thank goodness 
I'd done a little ObjectiveC work before.


Okay, finally got the app on the iPhone...wait a minute!?! WTF? A Motif 
button!?!


I think I found out about the iphone* calls when I hit this mailing 
list.  This mailing list seems to be quite good, usually, for information.


Later I wanted to do things for Android, and only then found out about 
the mobile* calls, which may/may not work on iPhone.


So, to recap, if I want to find out about a feature, I need to check:
1) User Guide
2) platform release notes, if applicable
3) Dictionary
4) the forums
5) the mailing lists
6) the example code and the tutorials
7) the academies
8) RevOnline might have examples too...maybe.

Oh bother! Now when I hit a roadblock I generally Google it first, as 
that seems to be the fastest way to learn about something.


Bottom Line, you simply can't say "Oh, we have a User Guide, if only 
you'd read it."


And all that was just for a button on iOS.  Try finding documentation on 
an accepted, approved, normal way to create a library!


The User Guide is a necessary part of the study of LiveCode, but only a 
part.


Perhaps Colin's book will plug the gaps, but my intuition says it will 
simply be yet another source of information that Colin will struggle to 
keep pace with LiveCode.


Hey, at this rate, we'll hit double digits of information sources soon!

Re: Threading or similar in LiveCode

[Ken Corey]

Send can mimic this behaviour.

You wouldn't want each car in its own 'thread', to be sure, as send has 
a certain amount of overhead...but it's a simple matter to set up 
recurring events:


on animate
  --do some animation stuff here
  -- if your drawing loop can take a variable amount of time
  -- then you'll want to get a little more clever about how long
  -- to wait before sending the next animate method
  send animate to me in 150 milliseconds
end animate

on preOpenCard
  -- do any setup necessary when opening the card:
  -- resizing graphics, etc
end preOpenCard

on openCard
  -- handle open card tasks

  -- start the animation
  send animate to me in 0 milliseconds
end openCard

If no such equivalent exists are there ways round this? For example
using sub-stacks etc each one behaving like a "fake thread"?

Re: Non-blocking transfers ...

[Ken Corey]

I've written a small asynchronous HTTP library based on rresocket that 
allows for access to headers.


Your code looks like this:

on openCard
  httpGet "http://my.url.path/blah","callBackFunctionName";
  [...]
end openCard

on callBackFunctionName
  [...]
  put httpBuildCookies() into tCookie
end callBackFunctionName

[...]
  -- somewhere later in the code
  set httpHeaders to tCookie
  httpGet "http://blah","newcallback"; -- this will have the cookies

Only problem is that rresocket doesn't work on Android, and I wanted to 
support Android, so I had to come up with another way to accomplish this.


Therefore, this library is a very rough outline.  It works, for some 
definition of works, but has not been stress tested, and I didn't 
explore it.


I can package it up in a few weeks, if anyone is interested.

Re: Raspberry PI

[Ken Corey]

Hrm...communication would seem to be a given already, isn't it? Can't 
LiveCode access RS-232 serial (real or emulated over USB) already?


The reason I'm excited about this kind of thing?  Friday my daughter 
came home from school for the summer with a set of DVD's with the 
software she had been using at school.  For each of these DVD's, her 
school must have paid some amount of money.  (Let's say £20 for the sake 
of it).


That presumes lots of things (we have a windows PC, it is powerful 
enough, there's space available on the machines, and the nous to be able 
to install it), not to mention suggesting tech support from school.


If any of those assumptions is wrong, it's money lost.

Purely as a hypothetical, let's say that there's an educational version 
of LiveCode running on the RPI, that supports a limited number of 
stacks/restricted functionality (no standalones?), etc, installed on 
RPI's at school that the kids are familiar with using already. (Of 
course, the stacks created with the ed version would have to be 
compatible with and expandable if they bought the full LiveCode IDE).


There were 30 kids in my daughter's year.  So, instead of £600, all the 
kids in that year could conceivably bring home the whole computer and 
the software stack for, say, £1500.  That would mean:
1) the school *knows* the software will work on the RPI, as it has been 
all year.
2) the kids are familiar with it, and can show off all their work to 
their parents.
3) It would seed LiveCode out there so that there /would/ be people who 
had seen or used it before.
4) runrev would see, I don't know...£300 or so (up to 10x that for a big 
school). Now multiply that by hundreds of schools?

5) benefits of scale allow the price of LiveCode to come down.

So, not hugely profitable, but gets that foot in the door. Seems if you 
can get a leg into the LEA for these schools, it'd be a no-brainer, and 
would be self-funding.


Heck, I'd kick into a kickstarter project just to see it demoed.

My kids' school is talking about getting iPads for all the kids. Now 
*that* I find distressing, as it is simply indoctrinating them into the 
"Apple *is* God, just shut-up-and-consume, don't program" mentality.


I already have to tell them 'no' when we walk by a sweets display at the 
grocer's.  Now I'm going to have to convince the little darlings that 
no, I cannot give them "just another" £1.99 for Angry Birds Space.


If they had their own RPI's, I could turn to them and say, with a 
straight face, "Why don't you *make* it yourself?"


Now, you get kids programming on the RPI, with the GPIO ports out for 
all to see, and I'd expect that a large percentage will want to play 
with that connector bit as well, coming into the Maker gestalt through 
the back door.


Though I personally, understand the draw of LiveCode being at a 
MakerFaire, I just don't see the business case for it.  Someone who paid 
£25 for a computer isn't going to spend hundreds on a full-blown 
IDE...and I can't see a way to sell to all RPI owners.  There's just no 
margin left on the darned things.


Again, I'm not Kevin, but I can't see the MakerFaire crowd paying his 
employee's salaries.

I still think Livecode needs to show up at a Maker Faire in a big way
working with Arduino, Leonardo, Raspberry PI, and Phidgets to then be
embraced by that community first. That is happening now in a very
small way. Livecode is such a natural match for these devices and the
people who use/buy them. I think getting that kind of leverage will
go a long way towards getting accepted in academic circles.

Well, I'm sure Kevin and crew have thought about it.

There's naught we can do from the user side.  Runrev just needs to see

That delay seems to be the best choice...how else can you tell if the

In a web browser, sometimes you don't care about scrolling, you can try 
to remove the wait this way:


http://cubiq.org/remove-onclick-delay-on-webkit-for-iphone

Or you can respond to the touchstart events, rather than the click events.

I built a label with multiple lines, put "1 2 3/n2 3 4/n3 4 5" into it 
and ran this line of code on it:


   add 1 to word 2 of line 2 of field "field"

It worked just as you'd expect it to.

However, this seems a very slow way to do it.

Hashes work a treat for this kind of thing.

on mouseUp
   -- keep track of how many times each word is used.
   repeat for each word tWord in field "txt"
  add 1 to tHash[tWord]
   end repeat

   -- print overview
   put the number of lines in field "txt" into field "numlines"
   put the number of words in field "txt" into field "numwords"
   put the number of lines in the keys of tHash into field "numuniq"

   -- print details
   repeat for each line tLine in the keys of tHash
 put tLine&" "&tHash[tLine]&CR after field "result"
   end repeat
end mouseUp

Simpler, and I'd wager significantly faster.

on mouseUp
put empty into field "Results"
repeat for each word tWord in field "Source"

   if tWord is among the words of field "Results" then

Re: iOS features

[Ken Corey]

1) Yes, *but* you have no access to headers sent back from a POST.

Much of the functionality you'd be looking for is provided by libURL, 
which is not supported (at least yet) on iOS and Android. (Please, 
/someone/ prove me wrong!)


So, if you're using a cookie-based authentication token as I did, you're 
going to have to work around somehow. iOS and to a greater degree 
Android have limitations on what you can do with http...to the point 
that I wrote some code to sit on top of the iOS socket external and 
perform correct http gets/puts...but then found you can't have externals 
on Android.


2) Theoretically yes, but I've not done it.
3) Theoretically yes, but I've not done it.
4) Not enough question to answer in full.  If the filesystem is mounted 
already, then probably (I've only retrieved files using http). If your 
files are made available with a local http server, then yes.


Trial version: seems to have most functionality (certainly enough to 
test the basics of your app), but you get a splash screen in the 
standalones you produce, and your app only runs for a short period of 
time before timing out.


Download the trial, and play with it.  Perhaps you'll like it.  If you 
run into specific questions, the folks on this list are quite helpful 
usually.

3) Ability to download files from a FTP server to the local app directory

4) Ability to copy files from a computer on the local network to the local

And what is possible with the free trial of Livecode Mobile - can we run in

Re: Is there a way to get an "exitGroup" behavior when someone clicks a non-group field

[Ken Corey]

Okay, here's a brute force approach for what I think you're asking 
about.  Put this in the card script.


You will need to deal with each special group you have like this.

local ingroup

on handleEnterGroup
   -- handle entering the group
   log "handleEnter"
end handleEnterGroup

on handleExitGroup
   -- handle exiting the group
   log "handleExit"
end handleExitGroup

on mousemove x,y
   if x,y is within the rect of grp "test" then
  if ingroup is false then
 put true into ingroup
 handleEnterGroup
  end if
   else
  if ingroup is true then
put false into ingroup
handleExitGroup
  end if
   end if
end mousemove

That take care of what you want to do?

Re: Standalone won't run

[Ken Corey]

Does your code get a chance to run at all?  If so, you can put alerts in 
to announce how far the app gets before it's crashing.


on preOpenStack
  answer "preOpenStack"
  [...regular code...]
end preOpenStack

on openStack
  answer "openStack"
  [...regular...]
end openStack

and so on.  If LiveCode is running at all before crashing, you get a 
chance to find the bug.


I'm finding with my stacks is that the preOpenCard and openCard handlers 
get run much less in the IDE during development.  I'd start by taking a 
hard look at those.


Richard, I don't think it's the executable bit, as the problem seems to 
be on both platforms, and the computers both are *trying* to run the 
standalone.  That wouldn't happen if the executable bit weren't set.

Even better: several Turtle graphics libraries, bezier graphics, and 
more.  Thanks for the link, I might never have found his website.


This proves my point completely.

RunRev shouldn't bother re-implementing the stuff Jim (and you) have 
done.  They should make sure it's easier to share it in the first place 
(by making sure RevOnline is easy to use to share).


I would have found resources in RevOnline. In fact, the first thing I 
did when I saw Jim's post was to go to RevOnline and see if anyone had 
uploaded information about a Turtle library...and of course they hadn't.


Apple (and Google and soon Microsoft) has been showing everyone that 
built-in stores are important.  It'd be a shame to let this one that 
RunRev has built, and people have started to use, languish.

Lovely analysis, and most accessible...

...but...you've provided great examples of turtle graphics in your stack.

Why should Mr. Miller and crew implement turtle graphics when it's quite 
possible for an enterprising teacher such as yourself to provide a 
library that does the same thing? (At least for the people you teach.)


Now, there'd be extra points for the RunRev team if they pushed a little 
harder on instructions for how to make a library to put into RevOnline, 
so future students could learn from it.


And I understand that there's trouble with RevOnline and uploading for 
them to work on too.


I'd rather they spent the time it would take to make native turtle 
graphics and spent it fixing RevOnline, and making sure we can all share.

Re: Works sometimes -- but not other times

[Ken Corey]

Uh...why are you using the on idle handler? Searching and showing a 
picture isn't something you're going to want to do a lot of times, it's 
something that is directly tied to keystrokes...and you're only going to 
want to do it once per keystroke. Also you feel it's causing a race 
condition...and if that is the case it's always best to not code 
yourself into that corner if you can help it.


That said, I'd guess that there's a problem with 'me' not being set to 
what you'd expect in the on idle handler.


But again, why can't this all be done in the keyDown handler? Fill the 
list, check for the end condition, display the photo if needed, done. 
(I'd write some code, but haven't had my coffee yet...:^)


on idle gets called regularly (how regularly is icontrolled by 
idleRate/idleTicks).  Is the list of users going to change in any way 
other than a keystroke?

Re: LiveCode 5.5.1 Released

[Ken Corey]

Here, here.  I'd definitely vote for this.

I mean, it's *so* bloody close:

1) Drop a label on your app that's inactive so you can see it, but it 
doesn't block events.


2) Define an error handler that prints the error message to the label 
(and truncates the label at xx lines).


All of this is possible in the existing Livecode, it's just translating 
the gobbeldygook into english that's troublesome. I've got a permanent 
bookmark to http://runrev.info/error.html, and it's pathetic that a 
third party needs to support such a tool.


If it can be done in the IDE, why can't that code be a library that's 
loaded for debugging in the device, and not loaded for release?

Perhaps I as a user can not view files nor folders within or under the

Then, I go to Computer / Programs / RunRev / Livecode 5.5 / June 2012

Now I can make a working LiveCode folder in my documents folder. So, I

Try setting the defaultFolder, writing your files, and see what happens.

mergDataGridScroller Control?

[Ken Corey]

Hi All,

In one of my projects, I was looking to create a DataGrid that works 
under iOS.


I managed to do it, and the performance was fine in the simulator, and 
at 320x480 on my iPad 2, but at full 1024x768 resolution on the iPad 2 
the performance was abominable.


When I asked the list, nobody had any suggestions, as the problem seemed 
to be a "group within a group" issue.


Today I noticed that Monte Goulding has a control called 
"mergDataGridScroller", and that it puts a datagrid into a scroller on 
iOS, and has a scripted solution on Android.


So, the obvious questions:
1) Is this better than my putting a datagrid into an iScroller on iOS?
2) does Android have its own native scroller now in LC5.5?
3) Monte, any plans to update this control for the later versions of LC?
4) I'm not sure...but is that control covered by a mergext license?

Thanks,

-Ken

Once you've got the data for the shape of each country at whatever level 
of detail you like, you can put the points into a grc, and make outlines 
of countries.  The grc can receive mouse events, etc.


Hope that helps.

Fairly tangentially, I don't know if you've seen it but the latest

worth the money. Each example is a less than 5 minute example, and they 
demo some pretty powerful stuff.


Perhaps even more powerful than the details of what they're showing, is 
the speed at which one is able to develop in LiveCode.  The Game Academy

How many developers have taken the path of converting
this stack from XML to other formats?

Searching the web, I found many free and paid converters from XML

Free XML to SWF
http://www.swixkit.com/

Paid XML to PDF, XPS, POSTSCRIPT, TIFF, Silverlight, Word, PowerPoint
http://www.ecrion.com/

So, my question could be stated in this form:
Have you written a specific Stack to XML script to
convert a stack to another file format?


XML is just a fancy, human-readable, way to format data.

A stack is more than just data, it encapsulates behaviours too. (Yes, 
you /could/ embed behaviour as data, but you'd need to translate it back 
again at a later date to be behaviour again.


For PDF, POSTSCRIPT, TIFF, and all the other static formats, you can get 
most of that right this second by taking a snapshot of your interface 
and embed the image in the format of your choice. (read about "export 
snapshot" in the dictionary).


Converting a stack to XML loses the behaviours.

As far as translation to other environments where there's enough 
language support you've got to come up with a business case.


I don't get out of bed in the morning without a business case.  To make 
it interesting, it must:

1) address a market that's not being addressed
2) or allow programming in 10% or less of the time it takes now

Learning to program in other environments is bound to be faster than 
writing something that understands how to write code for other 
environments...so I imagine you're going to have a hard sell here.

Perhaps you should be a little more aggressive with your icons.

To start with, point *all* images at a single holding pattern that is 
shipped with your app.


Then, in the code that displays a cell in the datagrid, do a 
asynchronous request to download that file, and replace the holding 
image with the downloaded one.


Once it's downloaded, it's local, and can be referenced quickly.

With LC it's much fewer lines of code than you'd think, and sounds

The image (each about 15bk) is fetched from  a web server.   So i set the filename of the 
image to the  "http:.." url.
When i scroll the records the scrolling stops several times, although all 
images seemed to be loaded.
When i use local files then the scrolling is smooth.
Is there something i can do?


Surely you don't want to fetch an image (even a small one) each time it 
needs to be displayed.


Why not download the images to specialFolderPath(documents), at which 
point you're local, so you can point your datagrid at them there?

Re: Age & Anniversary Calculations

What is the 'best' way to perform these 2 calculations with LiveCode?


'convert' just rocks.  Here's a couple of throwaways to show you how I'd 
approach it.  They probably aren't exactly what you need, but you'll get 
the idea.



1) Calculate a person's age, given a birthdate:


This one is a pain, as I ran it on Windows, and birthdays before 1970 
weren't natively handled.  I think this does the trick.

---
on mouseUp
   -- put the birthday into tBd,
   -- on windows, can't do before 1970!
   put "May 21 1965" into tBd

   -- handle < 1970 (is this just on windows?)
   set the itemdel to " "
   put item 3 of tBd into tBYear
   if tBYear < 12 then
  add 2000 to tBYear
   else if tBYear < 100 then
  add 1900 to tBYear
   end if
   put 0 into tBYearOffset

   if tBYear < 1970 then
  put 1970 - tBYear into tBYearOffset
  put 1970 into item 3 of tBd
   end if

   -- back to out regularly scheduled code
   set the itemdel to ","
   convert tBd to dateItems
   if the result is not empty then
  put "Got an error:"&the result
   else
  put the long time into tNow
  convert tNow to dateItems

  subtract tBYearOffset from item 1 of tBd

  put item 1 of tNow - item 1 of tBd into tBirthdays
  answer "You've had "&tBirthdays&" birthdays."
   end if
end mouseUp
---


2) Calculate whether an *anniversary* falls within a time frame - ie., within a 
week, within 2 weeks, within a month of today:


Something like this perhaps (written as in a button script)...watch out 
for wrapping:

---
on mouseUp
   -- get now as 2012,5,21,9,12,20,2 - today's date/time/day number
   put the long time into tNow
   convert  tNow to dateItems

   -- find out this year's anniversary, replace '7' and '8' as needed
   put tNow into tAnniv
   put 6 into item 2 of tAnniv
   put 8 into item 3 of tAnniv

   -- find out distance between...
   convert tNow to seconds
   convert tAnniv to seconds
   put tAnniv - tNow into tDiff
   if tDiff < 0 then
  answer "Already passed!"
   else
  convert tDiff to dateItems
  answer "it's in "&item 2 of tDiff&" months, "&item 3 of tDiff \
&" days, "&item 4 of tDiff&" hours."
   end if

   -- difference is shown as - 1970,2,18,0,0,0,4
   -- Ignore the year, as we purposely
end mouseUp
---

Hope this helps.

Re: SHIFTkey "Fun"

[Ken Corey]

Yes, there's no raw key access on MacOS

Why not code around it? Much as I'd like RunRev to respond to each and 
every request, it makes sense for them to fix the things we cannot do, 
rather than doing it the way we'd like.


In the stack script:
-
on openStack
  keysensor
end openStack

on keysensor
  if shiftKey() is down then
send "rawKeyDown "&65505 to this card in 0 milliseconds
  end if
  if controlKey() is down then
-- set this code "right"
send "rawKeyDown "&65506 to this card in 0 milliseconds   
  end if  if commandKey() is down then
-- set this code "right"
send "rawKeyDown "&65507 to this card in 0 milliseconds   
  end if  if shiftKey() is down then
-- set this code "right"
send "rawKeyDown "&65508 to this card in 0 milliseconds   
  end if

  -- change this to tradeoff cpu usage/responsiveness
  send "keysensor" to me in 200 milliseconds
end keysensor
-

On your card, create a field called 'log' with 20 or more lines, and put 
this code in the card's script:

-
on rawKeyDown RAWK
  put the milliseconds&" "&RAWK&cr before field log
  put (line 1 to 20 of field "log") into field "log"
end rawKeyDown
-

Doesn't that accomplish most of what you wanted in an admittedly 
bass-ackwards way?

I've checked that the debug mode is checked on my environment.  It is.

I've noticed that there are situations where existing breakpoints from

Click on the blue circle in a square to stop debugging.
Change the code.
If I've got a breakpoint I care about, I must unclick it, and reclick it 
for it to break.
Click on a field in my app window (it's a Windows 7 machine, so that 
click should also go through to the field I'm clicking on.)

Click on the field again.  No input cursor.
Click on the script Editor.
Click on the field again. (now the field has a flashing cursor).

Test the code.

It doesn't stop me, and now I am doing it automatically...but still it's 
frustrating.


I'm on Windows 7 64 bit, Livecode 5.5.1 dp2 (though I've seen this

Re: [TO] HTML5

[Ken Corey]

* When will the fact that my website is NOT written in HTML5 will
browsers
be unable to cope with it? *


What you're asking:
Whicih is better: HTML4 or HTML5?

The question needs to be refined.  It's like asking:
Which is better: Mac or PC?  Emacs or Vi?

There's no point in these questions, and nobody here is going to be able 
to give you useful input.


The better question is:
What version of HTML would I get the best return from?  That you can 
attempt to calculate in terms of money.


Translating to HTML5 has a cost in development time.  What that cost is 
depends on the current state of your web site, and what state to change 
to.  You haven't told us either of these at all, so there's no way for 
us to make suggestions on this point.


Not translating to HTML5 perhaps has a cost in lost opportunities, 
(though I don't know what those might be for you), or lost customers 
whose browsers don't handle HTML5 (so you'd have a cost to 
regain/convert/find new customers)


You need to either take all the measurements of browser types and OS 
used on your site to try to answer this one.  Without knowing what 
percentage of your user base uses old browsers, how could anyone on this 
list give you an answer?


Best of luck.

Hi Rod,

I don't have documentation, but I have to imagine the GPS takes up

Perhaps. I don't know enough to say.

Is there an easy way to test this?


My guess about it is that the outer group is being handled as a
texture, and as the inner group is changing that would mean the outer
groups texture has to be completely updated. If the outer group was
known to jut be a container, it wouldn't be processed as a texture,
but the inner groups would, and should perform well.

Meanwhile, what render settings are you using? If I'm right about the
issue, setting the acceleratedRendering to false might improve the
performance.


I set a toggle so I could set it to true or false at will, and didn't 
notice any difference between them.

Datagrid in scroller on iOS update speed?

[Ken Corey]

Hi All,

I've got a datagrid inside of an scroller on iOS.  I wouldn't call the 
datagrid complex, but there are 4 fields, varying height, and the rows 
are alternately coloured.


When it was shown on the screen at 320x480 it was fairly responsive., 
even on the device.


Of course, that looks funny on an ipad.

When I increase the size of everything on the screen, the response is 
sluggish indeed.


Are there any tricks for improving the speed of datagrids in scrollers I 
should be aware of? Any specific areas to look at?

Bug in custom fonts on iOS?

[Ken Corey]

Hi All,

I was wanting to add a little nicety to my iOS app, so I used three fonts:

Myriad Pro Regular.ttf
Myriad Pro Bold condensed.ttf
Myriad Pro Italic.ttf

So, I duly copied the files into the Copy Files pane of the Standalone 
Settings dialog, and then tried to run on the simulator.


No joy.  Only one of the fonts would appear.

After a bit of searching, I found David William's lesson about fonts on 
the runrev web site.  When I downloaded it, installed the fonts, and ran 
it on the iPad simulator, sure enough, only one of the fonts was listed: 
Myriad Pro (though Myriad Pro Cond was displayed in the window).


Doing a 'Get Info' for those fonts, they all come up with names like this:

Myriad Pro-Cond
Myriad Pro-Bold
Myriad Pro-Italic
etc...

Using my calibrated eye, the hyphen between 'Myriad Pro' and 'Cond' 
looks like an em-dash.  Could that break things?


Has anyone else seen this problem?  (bonus: anyone have a work around?)

Different row templates for a datagrid?

[Ken Corey]

Hi All,

I'm starting to think about the possibility of using my app on a Retina 
iOS device.


The central feature of my app is a datagrid that was originally designed 
for the older iOS screens.


I could just let it pixel double, but that just doesn't seem right, somehow.

After reading the datagrid documentation, it seems to me thta the 
"right" way to handle multiple resolutions is to have another, hidden, 
datagrid that has the right row template for a retina-class device, and 
if I detect that I'm on such a device, I'll use that template instead of 
mine.


Does that sound about right?

When they work, they can provide outstanding qualities (no installation

However, they are brittle, dependant upon fluctuating browser 
technology, firewall technology, always being online, rely on 
device/O.S. features being expressed in a browser, etc.


There are cases where web apps make sense...and if you find a niche like 
that more power to you, but I cannot believe that native apps are going 
away any time soon.


The iOS situation makes that abundantly clear. Web apps are 
significantly esier to write than native apps for many tasks. You can 
deploy them without Apple having a word to say about them. Thanks to 
Apple's WebKit efforts they look and work remarkably well...and yet...

Yes, it all helps!

The solution, for me, was to:
1) add this to my card where the group was:
on scrollerDidScroll OffsetX, OffsetY
  set "dgScrollbarDragV "&OffsetY to group ""
  set "dgScrollbarDragH "&OffsetX to group ""
end scrollerDidScroll
2) ensure that the rect and contentRect properties start correctly:
iphoneControlSet sScrollerId, "contentRect", (0,0,320,2500)
iphoneControlSet sScrollerId, "rect","0,0,320,460"
3) Use your maximum tip to set the height of both the datagrid and the 
contentRect of the scroller.
4) I don't know what the effect was, but the datagrid's position was

I was ready to decide it just couldn't be done in LiveCode when it was

Re: datagrid in iOS scroller (improved questions)

Hi Michael,

Thanks for writing.

The symptom is that when I touch and drag to scroll the formatted area
of the dataGris scrolls up too without revealing any more of the details
of itself.


Ah, that's better.  After a night's sleep, I can (hopefully) express 
myself better.


The symptom is that scroll events are used to set the hScroll and 
vScroll of the group, which moves the contents up.


What I want to do is forward the "scrollerDidScroll" method on to the 
datagrid, and let the datagrid handle the scrolling instead of moving a 
group.


Of course, the datagrid needs to be able to talk back to the scroller to 
tell it how big it is, where it is in the total height of its content, etc.


Added wrinkle: The datagrid does not have fixed-height rows.  They are 
variable.  That means that if I'm at the top of a 50 element datagrid, 
and displaying 10, the size of the other 40 haven't been created yet, 
and so I don't know how big they'll be.  I guess I could shoot for an 
average height, and just guess.


So I guess my improved questions would be:
1) How do I send scrollerDidScroll events into a datagrid?
2) How do I tell the scroller how big the datagrid is?
3) BONUS: if I don't have fixed height rows in the datagrid, how can I 
figure out how tall the datagrid is in total?

datagrid in iOS scroller

[Ken Corey]

Okay, so I decided to devote myself to a little toy project: download a 
list, display it to the user, and filter according to tags.  Precisely 
the sort of thing I'd want a high-level language for, and LiveCode 
should be ideal, as I want it on Android devices as well!


Okay, so I dig around and find dataGrid.  Brilliant, it does exactly 
what I want.


I spend the day figuring out how to make custom templates, populate 
things from a script, filter according to my custom needs, everything. 
Fantastic!


Okay, let's run it on iOS.  Oh rats.  That motif scrollbar has to go.

Okay, let's dig around a bit more.  Find a thread on the forums 
"DataGrid and a native Scroller".


After playing around with it, it seems to only work with a table 
datagrid, not a form datagrid.  Oh dear.


The symptom is that a limited amount of the datagrid is rendered at the 
beginning. When scrolled, that is painfully obvious.


Can anyone here save me from dataGrid purgatory?  Is there an easy 
solution, or should I just dive back into iOS tables?

Put the script into a button, and then for each image you create set the

I once saw a beginner write a c program like this:

blah(broken code;

}

She wondered why it didn't do anything.  When I told her to remove the

Turning off SSL Certificate Validation sounds an awful lot like "it

Font of menu on the Mac?

[Ken Corey]

Hi All,

I have an oddball problem.

I'm using a custom font to display cursive english writing.  This uses 
unicode characters, and non-standard glyphs (e.g. the left square 
bracket character U005B is a character to join between letters, not a 
bracket).


I would like to write a little tool to let me easily compare joins 
between letters.


I thought of three letters in a label like this:
  left-letter join-letter right-letter

To control this just needs 3 option menus, which when selected updates 
the label...


So I set the option buttons, and with the help of this brilliantly 
written article:

http://livecode.byu.edu/unicode/unicodeInRev.php
Have the correct letters showing in my option buttons (mostly).

However, on the Mac, when I do a pull down, it reverts to the system 
font, which shows "incorrect" characters (for my purposes).


Is there a way to control the font of menus on the Mac?

-Ken

Ctrl-Shift, right click did it!
Thank you!


My pleasure!

One other thing: I *never* use the 'Apply' button any more.  I always 
apply by using the 'Ctrl-S' save function. (Of course, it's Command-S on 
Macs).


That way, when I bork the IDE, or do something silly with 'answer' or 
'modal' or whatever, I am 10 seconds away from restarting LiveCode and 
being right where I was.  This happens often enough that IMNSHO the 
'Apply' button should simply be removed.


I've been burned a few times by programming for 1/2 an hour, hitting 
'Apply' and not saving, only for the IDE to lock, break, obscure itself 
with too many dialogs, or some other such thing. Teeth-gritting kinds of 
stuff.

I just had a quick play around...

On my machine (Windows 7, LiveCode 5.x), I can bring up a new main 
stack, and set it to be modal (it has no buttons to close, remove or 
anything).


Hold Ctrl-Shift, right click in the window, and you'll get a menu, where 
you can change the 'Stack Mode' to toplevel, where your controls come back.


(On my Mac, it seems to be Command-Ctrl-Shift left-click).

Well, transferring the app from one physical machine to another might

Could the screen resolution change if the user plugs in the Apple TV

Could it be possible for the user to change resolution (rotation)?

If there's use cases where the format changes that we know about, seems 
to make sense to assume that the screen is rather a temporary window, 
not a permanent fixture.

Directories on iOS?

[Ken Corey]

Hi All,

I found a /hugely/ useful error message just now.

My app is called "WriteOn.app", at least for the moment.

Hi All,

I'm hoping someone can help.

I called 'create folder' with the path to my app on my iPad:
/var/mobile/Applications/706ECCCF-DC1D-42F1-B71E-F3D96610DAEF/WriteOn.app/Downloaded

The error in 'the result' is "can't create that directory". Just lovely. 
Might as well put the "engine" light on my iPad. It would tell me as much.


Can anyone shed a tiny bit more light on that error message?
It /shouldn't/ be permissions, because it's within my app's sandbox.
It can't be space, as I've got 2.4GB remaining.
It shouldn't be rights, as the standalone downloads to the iPad just 
fine and is attempting to run when this error happens.
I don't have AFAICT any other app using the same signature (but that 
shouldn't matter anyway, should it)?


Are there any other reasons why one can't create a folder on iOS from 
within LiveCode?


Thanks,

-Ken

Re: Spinning object animation

[Ken Corey]

The frames of the vase are in the opposite order of the globe. 
Rearrange the frames in the opposite order (I did it in GIMP in < 1 
minute).  For the vase, frame 2 becomes frame 12, frame 3 becomes 11, 
4->10, 5->9, 6->8.  It's just swapping the two frames.


Also, the movement felt wrong to me.  If you started moving towards the 
right, but now are moving back towards the left, shouldn't the item you 
appear to have grabbed also be moving towards the left?  Something like 
this:


on mouseMove x,y
   if tMouse = 1  then
  put trunc((tLoc-x)/5) into tDiff

  put (tImageFrame + tDiff) mod (the framecount of img 1) \
into tCFrame

  if tCFrame<0 then
 add the framecount of img 1 to tCFrame
  end if
  set the currentframe of img 1 to tCFrame
   end if
end mouseMove

Android LiveCode and ARM Linux will have a common linux-based core. Of

But I'd *love* to be able to sell to a customer a "throw-away" computer. 
 Buy the software for $40 and we'll throw in the computer to run it on! 
 Open-source, and unlocked.


Once the RPi foundation proves that it can ramp up to meet demand, I'd

If the hardware isn't going to cost anything, where are they going to 
make any money at all?

Sounds to me like you're in active ftp mode...which is strange as 
passive mode is the default.

Try:
libURLSetFTPMode "passive"

If that doesn't work, try
libURLSetFTPMode "active"

I've not played with FTP in LiveCode, but I'd bet that solves this one.
