RE: Speed test in LC application

[Ralph DiMola via use-livecode]

I see some unexplainable delays from an app to a LC web service on on-rev
that I have not started to debug yet. I almost looks like a DNS resolution
delay. I am going to WireShark the lan and see what's going on. I will let
you know what I find.

Subject: Speed test in LC application

Hi,

I'm sometimes having trouble with my application downloading audio and image
files from a remote server when they are requested. I'm thinking of adding
some diagnostic tools to the application to see what is going on and I would
like to know if anyone has experience with this and can give me advice.

My application, "Music in the Air," a music exploration/history program for
music students is heavily dependent on audio and image files being
downloaded from a remote server (currently Amazon AWS) while the user
peruses the program. The user chooses a musical work to view and play and
immediately the program downloads 2 to 100+ image files (gifs averaging 50
KB each) of the musical notation. When the user start the audio playing, the
program loads the player with a remote audio file (10-50 MB). This library
of audio and images is 2 GB+, so the need to store and serve it as needed.

However, users are reporting that possibly 10-15% of the time the music
stalls while playing at the beginning, pointing to some bottleneck in their
Internet connection or local network. These users are usually on a fast,
high-capacity university network, getting files from a robust server, so
they shouldn't normally see this happen, and I would like to track down what
is going on. Also when this program is published, it will be deployed to
areas of the world where an Internet connection is not so robust. So I'm
thinking more and more that it would be vitally important to include tests
within the program to monitor and report, if necessary, on the user's
ongoing connection and bandwidth while the program is being used and send me
diagnostics when there are problems.

Does anyone have any experience with this kind of thing that I could draw
upon or employ?

Color Conversion - RGB to HSV and back... (almost)

[Alejandro Tejada via use-livecode]

Hi Mike,

Many thanks for posting a link to your
compilation stack: Master Library.

How many new LiveCode users are aware of this
wonderful resource? Thanks again for posting this.

Sorry for replying so late, but recently I am not feeling well.
Food intoxication is my educated guess... :(
Because of this, I have been posting only to the forums,
where I could edit or delete my own messages that
do not say what I meant. :)

Your HSV and RGB conversion functions works great
with only a few changes:

In Function HSVtoRGB this line:

put var_2  var_R
should be
put var_2 into var_R

and

put abs(trunc(var_R * 255)) into R  //RGB results from 0 to 255
put abs(trunc(var_G * 255)) into G
put abs(trunc(var_B * 255)) into B

works better if we replace trunc() for round().

After this small change, HSV is converted
back to RGB with 100% precision. :D

By the way, I posted a stack in the forums
that converts RGB colors of an image to
HSV colors. After this conversion, JPEG
compression artifacts become much more
evident and some strange patches of color
appears in the most unexpected places. :o

You could download the stack from this forum thread:
http://forums.livecode.com/viewtopic.php?f=10=29172

Now, I am looking for some script that allows
users to replace all 6 HSV color and their 7 gradients
(red to orange, orange to yellow, yellow to green
green to cyan, cyan to blue, blue to magenta,
magenta to red ) with colors of their own selection.

Have a nice weekend.
Keep up your Great Work!

Al

mouseMove & backgoundBehavior

[Jim Lambert via use-livecode]

Make a group that is smaller than your card.
Place this in the group’s script:
on mousemove newMouseH, newMouseV
put newMouseH, newMouseV
end mousemove

When the cursor moves around within the group the current mouseLoc is put into 
the message box. When the cursor moves outside of the group the mouseloc is no 
longer placed into the message box.

Next set the backgroundBehaviour of the group to TRUE.

Now wherever the cursor is within the CARD the mouseLoc is placed in the 
message box regardless of whether the cursor is within or without the rect of 
the group.

The dictionary states, "The mouseMove message is sent to the control the mouse 
pointer is over, or to the card if no control is under the mouse pointer.”

It is true that a background group is not 'officially' on a card (rather it’s 
on the background in HyperCard parlance.) But why would the mousemove message 
get passed to the card when the mouse is outside of the background group 
containing that handler?

Is this a bug or expected behavior?

Thanks,
Jim Lambert

Re: on tabKey - what field contains the blinking curser?

[Roger Eller via use-livecode]

When I tab to the next field, I want to select after the field content, or
in other words place the blinking bar at the end of whatever is already
there.  By default, it is placing it in front of the field content.

One way:

on openfield
  put the name of the target
end openfield

I'm not sure if you want to trap a message though. The selectedField 
will return identification if you're querying from inside another handler.

Re: Swiping between cards - metaphor end-of-the-road?

[Sannyasin Brahmanathaswami via use-livecode]

This is an important subject, I've been meaning to write this for a couple of 
weeks, but Richard got here first.

our current app.

(if anyone is interested I can send you the git repo link off line…it is 
public;  I just don't want to post It public)

use click and swipe "everywhere"

the model is simple: group of rows (smaller groups) whole "portal" group is 
scrollable

each row is a "hyper link" to 
a) a dynamic rebuild of the card with differernt rows
b) open another *module.livecode binary stack
c) open a stack that has a browser widget on it the URL to view pass to it 
dynamically.

Seeims simple enough, works great on desk top… so much promise for a highly 
scalable modular app. 

 but are are getting major failures on mobile and I have been wrestling for 
weeks with the the simple problem of just opening and closing stacks without 
crashing or render issuea (mostly on Android) and performance (super slow on 
some android devices) Once any given stack is actually opened and rendering 
correctly, it works great.  

Anyway, the need to respond to a touch/aka/mouseup  OR swipe the group up and 
down.

That's the tricky bit

Currently we are (pseudo code)

 using locals to get the tStartLoc on mousedown and using

if the  abs(the endloc) > 10  # assume swipe
else
assume tap: fire the hyper link

I'm having issue with this. can't quite figure out why, but I have to tap twice 
to fire the touch event… could be the code needs top be optimized there.  and 
standard mouse/widget/icon/image with just a mouseup alone, fires instantly.

This is not exactly focusing on the card metaphor… but the issues are the same. 
(I think)  Because you might want to trap the touch on a card and not actually 
swipe left or right, group up/down/sideways


Suffice it so say we do need improvements here.  I have a lot of design 
requirements that would use this algorithm

all modern apps do this… verycommon now to load (sometimes over load IMHO) a 
single interface with scrolling groups going sideways… all of which are 
basically create a giant TOC/Index to dive into some other screen/list/listen 
to music (Spotify is a very good model)


" While apps are generally built in
a hierarchical fashion, there are instances where
horizontal navigation can flatten vertical hierarchies
and make access to related data items faster and more
enjoyable."


Anyone else doing the 

touch or swipe  thing?  on a scrolling group/card can you share your code 
methods for this?  I would like to test and improve what we have if possible.

Button where appropriate, swiping where appropriate.


iOS:
Use touch gestures to create fluidity. Make it easy to move
through your interface with minimum friction. For example,
you could let people swipe from the side of the screen to
return to the previous screen.




Android:
Efficient navigation is one of the cornerstones of a
well-designed app. While apps are generally built in
a hierarchical fashion, there are instances where
horizontal navigation can flatten vertical hierarchies
and make access to related data items faster and more
enjoyable. Swipe views allow the user to efficiently
move from item to item using a simple gesture and
thereby make browsing and consuming data a more
fluent experience.

Does it run arm-emulation automatically or do we need to warn it?

The parts I use that are processor-intensive are running in the browser widget,

I suppose it's related, but indirectly.  That request is for access to 
iOS-specific gesture APIs.  Those should be accessible through FFI, no?


Either way, the gestures themselves are only part of the challenge.  In 
fact, for card swiping we need only one, a swipe. The bigger part is 
handling the dual-card render during the gesture.

Button where appropriate, swiping where appropriate.


iOS:
   Use touch gestures to create fluidity. Make it easy to move
   through your interface with minimum friction. For example,
   you could let people swipe from the side of the screen to
   return to the previous screen.



Android:
   Efficient navigation is one of the cornerstones of a
   well-designed app. While apps are generally built in
   a hierarchical fashion, there are instances where
   horizontal navigation can flatten vertical hierarchies
   and make access to related data items faster and more
   enjoyable. Swipe views allow the user to efficiently
   move from item to item using a simple gesture and
   thereby make browsing and consuming data a more
   fluent experience.

Swiping between cards - metaphor end-of-the-road?

[Richard Gaskin via use-livecode]

I stumbled across this thread and it got me thinking:
http://forums.livecode.com/viewtopic.php?f=7=29184

LC has cards, which are great for many things but somewhat limited.

For example, as the OP asks about there: how does one swipe between them?

That seems a perfectly reasonable expectation, given what cards are and 
the central role they play in LC's object model and language.


And yet we don't really have any way of doing that.

Doing it right on mobile would mean some drag-triggered transition which 
responds to the drag movement itself, and could be canceled if the user 
releases their finger before a certain mid-screen threshold is reached.


Of course we can do that with groups, but consider what that means:

We'd have to construct all of our layouts on a single card, and have 
some means of moving the groups on and off screen as needed, both during 
development and at runtime.


All doable, and not too much of a brain-bender.

But it's work.  And non-obvious to newcomers.  And even for experienced 
devs it's tedious.


And at that point, the beautiful simplicity of the card metaphor breaks 
down.  Indeed, it's no longer even relevant because we're not using 
cards at all, but groups on a single card.


At that point, some of the advantage of choosing LiveCode is lost, 
because one of the most central elements of its object model is no 
longer a best fit for today's designs.


Modern UIs (most mobile and increasingly on desktop as well) benefit 
from providing a sense of unifying flow with, among other things, 
interactive drag actions as transitions between screen layouts.


I was considering putting in a feature request for a new drag 
transition, but before I do I think we need some design work to figure 
out exactly what it should do and how we work with it.


It's not even a transition per se, since those are discrete visual 
operations performed after a user action has been completed (e.g., a 
mouses click or a menu selection).


This seems perhaps a good candidate for a property, maybe something like 
"the dragTransitions" of a stack.  When true, any drag actions not 
handled by any script would be handled by the engine by dragging a 
transition from card to card according to the direction of the drag.


That may be too simplistic, though. Do we really want free travel 
between all cards in a stack?  If not, how do we specify what happens in 
response to a drag when we want a card-to-card transition?

Re: Make numberFormat even better

[Mike Kerner via use-livecode]

Whenever we decide we're done with this, someone needs to send me the code
and I'll throw it up on github, since I'd like to have a central repo for
helpful code, especially since with git and levure we have a pretty easy
way of adding those modules to our projects.

That does look very nice indeed.  If that formatting is factored in a 
way that would lend itself to a generalized behavior script for fields, 
and if Curry or Hugh were inclined to contribute some existing code it 
would help the project get a running start.

In more popular languages like Python or R, or pretty much any open 
source tool (among programming languages that would be nearly all of 
them), what we commonly see is one person with an itch to scratch writes 
a something to fit their needs, posts it to a code-sharing repository 
like Github, and others come along an augment it.  Over time it grows 
into an ever more mature, robust, general-purpose solution, but even out 
of the starting gate it's useful, and only gets better over time.


A small project of this scope wouldn't need hundreds of developers. I 
can't imagine more than half a dozen contributing to it.  Most of the 
coding could be done by one person in less than a day.


Where more eyeballs may be most useful would be in the design.  The 
property names need to make sense, and ideally there would be ways to 
use this for list columns in addition to individual fields, so we'd need 
to come up with a sensible way to handle that.


We'd probably want to ask ourselves if this should be a function or a 
property?


As a property it feels most natural, applying formatting specs to a 
given object.  But there are tradeoffs there, including being able to 
have only one behavior script applied to an object, and the issue with 
getProp and setProp being unreliable in any environment in which the 
lockMessages might be set to true.


As a function it would be far simpler to design, but would require the 
user to code for it, rather than having it be a property you set once 
and never need to think about it again.


There may be other options too.

And the choice of whether such a library be written in LC Script or LC 
Builder.  The latter offers direct support for documentation and 
Inspector options (though it would certainly be useful to see those 
options available for LC Script as well, though that's another discussion).


We could brainstorm those design aspects here and now if we want.

By design LC does not allow overriding built-in functions the way 
HyperCard used to.  When I asked Dr. Raney about this decision, he asked 
me to observe the execution speed difference between the two, and noted 
that his token table was kept very trim with this decision.  He also 
invited me to come up with a case in which it was truly necessary to 
override built-in functions as opposed to using a new name for the new 
function.  In all these years I couldn't come up with one.


So in short, I think a new name for new functionality may be best.

To be included in the LC install it needs to be good, and if implemented 
as a function it may perhaps eventually be included with the other 
handlers currently in the revCommon lib.


But that would require that it be field-tested, so early adopters would 
first use it as a library or behavior they download and install.


It may be that the engine team may later borrow some of the design from 
the scripted version for inclusion in the engine.  But until Mark 
Waddingham posts "Yes, we have time and will do that this week" we'll 
need to consider options that aren't dependent on the engine team.  And 
as Curry and Hugh have shown, these things can be done by a single 
person in script, valuable even as add-ons.



[I was tempted to write a rant about package managers here, about how 
every popular language has one and we don't, and the relationship 
between platform adoption and the ease with which one can find and use 
extensions.but that's probably best left for another thread.]

At the bottom of the "Contributing" page for the LC code base there are 
links to C++ style guides:

I don't know of such a guide for scripted contributions.  That would be

Re: Make numberFormat even better AND Cognitive Load

[prothero--- via use-livecode]

Folks,
This thread addresses two issues with numbers. The main issue being discussed 
is the display of numbers. This is very important and the main point of 
diddling with numberformat. I like the idea of making a behavior we can all use 
to format numbers in a variety of ways.

The other one is the internal representation of numbers in the engine. 
Currently, it seems there are either strings or numbers and the engine converts 
between the two, depending on rules that it carries internally. It's partially 
my bad that this issue got incorporated into this thread. But where I saw the 
problem was in the discussion of array keys and how the engine treated a[1] 
different from a[01]. It's really the way arrays work and that the keys are 
really text, not numbers (at least, that's what I understand from the 
discussion). I use arrays a lot and love them for this. They become a bit 
inconvenient when all I want is a numerically indexed array without gaps. But 
it's only a minor issue for me. When it comes to integers, I only need to 
decide whether to round or trunc a value. 

When speed issues arise, the most transparent way of dealing with this would be 
to declare an integer type variable, and the engine would then treat all 
instances of that variable as an integer. We already declare variables as local 
or global, and I see no conflict with the xTalk language philosophy in adding 
that property to a variable.

Ok, I'll shut up about this for now. Sorry to unfocus the thread.

Best,
Bill P

Make numberFormat even better

[Roland Huettmann via use-livecode]

Thank you, Richard, Curry, Mark...

It is a very nice approach that Curry already realized: and it is available:
http://curryk.com/ck-num-format.pngn better

But what I do not yet understand is how to make a joint effort with
hundreds of developers ))) available to ALL of us in practical terms --
seamlessly.

For any newbie and for those using formatting all the time, do we have to
load a separate library or would it be supported out of the IDE? For
example, could the numberFormat or format() functions be overwritten so
that simply using LiveCode Script it would work the way we defined and this
out of the engine?

Or is it a new function? And could it be shipped with the product if
approved? Again, we are thinking of Excel style formatting that any user,
even non-programmers, often enough know about.

And how can we contribute? Is it a joint effort where someone is delegating
the task? Or is it the work of someone taking the time to write it for ALL
of us? And, also I wrote about this, I feel a bit shy to think that I could
provide code that would or could really be seen as a viable contribution. I
do not know what really makes LiveCode Script be quality code?

Is there any guide telling that such LiveCode Script following certain
style and rules and using the best performant way will be accepted as
"quality code"?

I know about naming variables (naming conventions), and I assume that
comments could also follow style (comments disabling parts of code,
comments to the code, etc.), and even possibly assigning variable names
that are common to everybody -- for example, I have a style to always name
sames types of variables the same way: For example for variables containing
file information: tFileName (with extension), tFilePath (full absolute
path), tFolderPath (without ending slash), tShortFileName (without
extension), tFileExtension (just the extension), or i, j, k... as counters.
Because I am lazy, I find such conventions (for private use, or for
community use) very helpful. I assume there are 30-50 standardized names
that could be shared to make code easily readable and that also newbies
should know about.

Then, again to be practical, how would we name fields and how would we name
custom properties indicating how code should work with a field and format
such field?

Assumed, there is a currency style field with a format such as
"$#,###.00":=  "$1,000.00" where a style property would be set for this
field. This field also serves as a database field and should "know" to
which data source it is connected and also may know in which order database
fields appear. That is another custom property. So, a command saving to the
database would look up all such fields, convert strings to numbers the
database understands, already know the underlying database field name
without any further scripting, and simply saves whatever is there. And,
yes, there is a behavior script assigned to such field - and it depends
whether data is entered manually, or it is put into the field through a
script.

Another field could present a scientific notation and accept and display
scientific notations.

This can grow to become a very dynamic behavior when strictly following a
certain style that is used by everybody.

Or am I thinking into the wrong direction?

I am not worrying doing it for myself. I am more thinking when we are
offering this as an adopted standard.

With dates, there is always a problem in Central Europe because the system
date displays a date string that is not seen by the engine to be a date. It
is NOT a date for LiveCode Script. Here, we have DD/MM/YYY or DD.MM..
So, I must always convert such date anyway to allow LiveCode testing it to
be a valid date. For SQLite and other databases we need it to be
"-MM-DD" and internally we might just use the seconds.

Then, adding field "A" of type date to field "B" of type date (or
variables/arrays representing such fields) should result in a new date
without even having to think.

And I assume it would be best for users setting the field format using a
context menu clicking on the field in questions and setting such behavior
and formatting options -- if this is not part of the Property Inspector.
Such context menu could open some Settings pane when needed.

Or can we, should we, simple users, modify the Property Inspector?

I assume it would be best if someone following the guides and with deep
experience would implement while the rest of us could contribute with
testing, discussing, etc. ?

And because of all this, and for joint work especially, I would really
appreciate more standards, more guides for "best practice", even strict
rules -- not to make things not work when breaking such rules, but to make
things easier and more transparent in the other 99% of cases.

An anomaly in the "read from file" command?

[Quentin Long via use-livecode]

First off, thanks to Alan Stenhouse for zeroing in on my filter-related 
mistake. Any number fo people *could* have done so, but it was Alan who 
actually did the deed. So, yay Alan!

Second: I discovered something odd as a result of another mistake I made. My 
mistake:

ask file "What do you want to read?"
put it into DisFile
read from file DisFile until EOF
put it into fld "This Field"

What went into field "This Field" was the contents of the *variable* DisFile, 
*not* the contents of the *file* whose name is stored in the variable DisFile. 
This is because of how the pseudo-variable "it" behaves, i suspect.

My mistake was that I didn't *open* file DisFile before reading it, of course. 
And once I did open the file, the reading went on normally, and the contents of 
the field did indeed end up in the field "This Field". So, bad on me for not 
opening the file first, good on me for recognizing & fixing that lapse without 
external assistance. But I do have a question:

Why didn't I get an error message when I tried to read from a file that hadn't 
been opened yet? Shouldn't LiveCode have gotten fussy about that?
