It is, as you said, going to need sin and cos. The X movement would be 30 * 
cos(37/180 * Pi), and the Y movement would be 30 * sin(37/180 * Pi), in your 
example case.

K heres the required parts..

*## takes length and the angle in radians and returns vector as x,y offsets*
function aLenToVector pLen pAngle
return pLen * sin(pAngle),pLen * cos(pAngle)
end aLenToVector

*## takes degrees and changes to radians*
function dToRadians pDegrees
 return pDegrees / 180 * pi
end dToRadians

With those 2 things, you should be able to move your turtle.

The problem is not with drawing the line.

The problem is how, when the turtle's "nose" is pointing at, say, 37 
degrees from the vertical

one can get it to move FORWARD for 30 units.

If you would like the “turtle” to move to the points of the line then, lock 
screen, draw the line, hide the line and unlock the screen before you start 
moving the “turtle”. Then no-one will ever see the line and you can delete last 
graphic once the turtle has stopped moving.

fontLanguage()

2017-01-30 Thread Phil Davis via use-livecode 

Hi folks,

In LC 8.1.2 I have checked 'the fontLanguage' of all my installed fonts 
and get nothing but 'ansi', even for my Arabic fonts. In some previous 
version of LC my experience was different - guess I'll go digging and 
see what I find.


Does anyone have different outcomes with fontLanguage() in 8.1.2?

Thanks -
Phil Davis

Depending on what version of LC you're using,k and if you're using the
widget, or openrevbrowser
look at revBrowserAddJavascriptHandler in the dictionary.

If using the widget, use the dropdown to select the browser widget in the

JavaScript, Browser Object, VR with Hotspots?

2017-01-30 Thread JOHN PATTEN via use-livecode 
Hi All,

I’m not sure if this is possible with Livecode, but I thought I’d ask anyways. 

I have a html5 panorama I created in a trial version of Pano2VR. I posted it up 
here: http://jpatten.on-rev.com/vrjs/index.html 


This pano has one hot spot that just throws a JavaScript alert, “Hello World.”  
So I know I can create a Javascript inside a hotspot in the pano using the 
Pano2VR app.

Here are my questions.

1. Can Livecode intercept the Javascript result in the browser object and act 
on it?  If it can, I’m guessing I could have it return text and then have 
Livecode run an action. Something like…  if varText = “picture 1” then, show 
picture one … else/switch if vartex = "picture 2" then open "picture 2", etc. 
etc. etc.


2. I would like to have hotspots in a panoramic image run JavaScripts that 
LiveCode intercepts, and then act on what it catches to runs scripts in the 
stack. One hot spot might open and image. Another might open a substack, etc. 
etc. all within the LiveCode project. The Browser Object is used only to 
present the panoramic image, and the pano image acts as s pseudo navigation 
object for additional content.

Anybody have a simple example of what the Javascript in the pano might look 
like, as opposed to just an alert? What scripts would I use to capture and act 
on the Javascript in the browser object?

Or, maybe this is not possible…?

Thank you!

Re: Built-in JSON functions not working in standalone

2017-01-30 Thread Monte Goulding via use-livecode 
Hmm… yes the new support library for mergJSON should be now be included in 
standalones if you include mergJSON. Please open a bug report if that’s not the 
case so we can sort the issue out. Note that it will *not* be included via 
search for inclusions.

Cheers

Re: Built-in JSON functions not working in standalone

JSONToArray and ArrayToJSON are both in the dictionary, if these functions
don't do what they're advertised to do, then someone needs to revise the
dictionary

from the Livecode Dictionary:

JSONToArray

Type  function
Syntax  JSONToArray(pJSON)
Associationsws.goulding.script-library.mergjson

Summary
Parse JSON to a LiveCode array

To my knowledge, the functions are not built into Livecode. You may have a 
stack loaded and part of the message path that has those functions there 
already. You will need to add the functions to your project in order to 
parse/encode JSON.

If you would like the “turtle” to move to the points of the line then, lock 
screen, draw the line, hide the line and unlock the screen before you start 
moving the “turtle”. Then no-one will ever see the line and you can delete last 
graphic once the turtle has stopped moving.

Re: Built-in JSON functions not working in standalone

2017-01-30 Thread pink via use-livecode 
I'm basing my comments on what I see in the Livecode Dictionary:

"The mergJSON external itself can not parse JSON to and from
multi-dimensional arrays. This is achieved through JSONToArray and
ArrayToJSON script functions provided in this library. The implementations
in this library are intented to be generally useful in addition to providing
a basis for implementations focussed on edge cases such as ArrayToJSON that
forces a known element to be an object."

The JSONToArray and ArrayToJSON functions are built into Livecode now.
Again, they work fine in the IDE, it is just in the standalone that it
fails.

Yertle the Turtle

2017-01-30 Thread Richmond Mathewson via use-livecode 

Having imported an SVG image of a tortoise into a stack . . .

Being a fan of Seymour Papert . . .

I thought I'd try and implement turtle graphics in Livecode.

But came up against something awkward . . .

[As a caveat, I should like to point out I don't know how the following 
is implemented

in any other languages either]

1. Rotating my turtle widget is easy.

2. But telling the turtle to move forwards or backwards is not easy at all:

In LOGO one can tell the turtle to turn left by, say, 30 degrees, and 
then move forward 20 units.


But in LiveCode, as far as I know, one can either move an object by 
setting 2 coordinates,

or by 'set the loc'.

2.1. Now if I want my turtle, rotated at 30 degrees to move forward by 
20 units I will have to mess
around with SINE and COSINE and probably not end up with the turtle 
moving exactly 20 units at 30

degrees from the vertical.

2.2. I wonder how my turtle will be seen to draw a pen line from the two 
ends of the "line".


Richmond.

JLM, Thanks for the clarification. BR, Another way to do this without using

This has to do with the default behavior of LC and the OS it runs on. By
default, LC mobile apps quit when they are not frontmost. The behavior after
that depends on the OS.

On Android, the LC app will remain in RAM until the OS needs the memory, at
which point it will quit. If the user goes back to the LC app before it has
been removed from memory, the user will return to the place it last left
off. If the app has been removed, it re-launches to its opening screen.

On iOS the app is not retained in RAM, it always quits. Ralph provided the
work-around that allows the app to run in the background. It is not
supported and can fail depending on what the app does. If you use it, test
to make sure it works reliably.

JSONToArray isn't part of mergJSON. It is a handler that you add to a stack
in the message path. See the README:

 Sounds like an easy enough fix.  (or instead of rewriting the thing, you
might be able to read in the item and "replace cr with empty" which I
guess is rewriting, so nevermind!)

Re: Dirty HTTP Launch

2017-01-30 Thread Tom Glod via use-livecode 
the URL is read as an ITEM from a line in a file that was generated by PHP
(which is I am sure where the cr comes from)

PHP code just concatnates label "HTTP Link, item delimiter "=" and the URL
starting with HTTP.

I think I will just write a little repeat loop to rewrite the URL before I
send it off to the launch command.   Gonna try format function too

Re: Built-in JSON functions not working in standalone

2017-01-30 Thread pink via use-livecode 
JSON Library is the LCB library with the command JsonImport and JsonExport.

Those are not the commands that I am using. 

I am using JSONToArray which is part of the mergjson external. I've included
it in builds and I am still stuck.

Re: Built-in JSON functions not working in standalone

2017-01-30 Thread Bob Hall via use-livecode 
The Library needs to be on the inclusion list for it to work in a Standalone. 
In Standalone prefs click General->Select Inclusions for Standalone (note: I do 
not bank on the auto-include feature).

Then click the “Inclusions” icon and wait just a second as the inclusions 
render.

Look for JSON Library and include it. Should work then.

Built-in JSON functions not working in standalone

2017-01-30 Thread pink via use-livecode 
I made a single change in a program that has caused it to stop working:

I switched from using FastJSON  to using the built-in JSONToArray functions. 
To be clear, I'm not talking about JsonImport which I cannot use for other
reasons.

I built standalones for Windows and Linux using LC 8.1.2 Indy, and neither
work.
I've tried searching for inclusions, I'v tried manually selecting inclusions
and including mergJSON in the build.

When I say that they do not work, I mean that any observable instance where
data is retrieved and is then displayed in some manner, the program stops
doing whatever script I have it doing. Again, this is just in the
standalone, everything works fine in the IDE.

Did I miss a step in order to get these functions to work in my standalones?

Looking for advice on database syncing

2017-01-30 Thread pink via use-livecode 
I am working on a new section of my CouchDB library to synchronize a Couch
database with a local array. Before I wade too far in, I wanted to get to
see if my plan makes sense..

I have two questions I'm hoping for input on:
1. Can anyone think of a scenario I am missing?
2. Is there anything missing from the conflict resolution options?

CouchDB uses revision numbers to keep track of changes, so I am trying to
map out all the possible scenarios that should exist.

quick definitions:
   localRev: revision number of the local document from last sync
   serverRev: revision number of the server document
   localDirty: boolean flag that says that the local document has been
edited since last sync  
   
Comparing each document's rev numbers, I envision the following scenarios:
   
1. document is unchanged
localRev = serverRev AND localDirty = false
action: ignore during sync

2. server document is newer
localRev < serverRev AND localDirty = false
action: download latest version

3. document has been edited locally, local copy is the same as server
localRev = serverRev AND localDirty = true
action: upload new version

4. document has been edited locally, BUT server copy is newer
localRev < serverRev AND localDirty = true
action: depends on conflict resolution settings (see below)

5. local document doesn't exist
localRev = empty and serverRev > 0
action: download document

6. local document is new, doesn't exist on server yet
localRev > 0 and serverRev = empty
action: upload document

7. The revision number is generated by the server, so there should be no
reason why localRev > serverRev unless the user has switched to a different
server that has been replicating with the original, and is behind.
action: it's an unlikely scenario... upload local document

8. if the record is marked as deleted locally or on the server, it is
deleted everywhere

Conflict resolution:
These are the options I am planning on for conflict resolution, they will
get passed as a param in the sync function

local: in conflict, keep local, discard server
server: in conflict, keep server, discard local
localmerge: keep local document, insert server document as a subkey in local
document "conflict"
servermerge: keep server document, insert local document as a subkey in
local document "conflict"
keepboth: rename "_id" of local document and upload it, download server
version

RE: Launch URL with Link Back to LC App

2017-01-30 Thread Ralph DiMola via use-livecode 
BR,

This has been described at the ol' "plist hack":
Look at the package contents of the LC.app version your using. Navigate to the 
Contents>Tools>Runtime>iOS folder and set the permissions for write access to 
the "Device-x_x" folders. Then edit the "Settings.plist" files and delete the 2 
lines.. UIApplicationExitsOnSuspend
${APPLICATION_EXITS_ON_SUSPEND}

Rebuild your app. The app will only close if you "Quit" it by LC script or the 
app window is not displayed and iOS needs the memory (although I have never had 
the latter happen)

Hope this helps...

HTML model: Natural Flow

HTML has something we don't:  "natural flow", a set of conventions for 
object placement that are implied and do not need to be specified in 
order to get some form of reasonably useful layout.


HTML also has something else - CSS, The object inheritance model in LC 
allows you to inherit properties (e.g. colour, margins, etc.) for your 
objects - but it doesn't have any easy way to classify together  (I 
wanted to say "group" but that would get confusing :-) a number of 
objects. So in the example here, there were a bunch of buttons ( 
entries) whose properties could be changed consistently by tweaking the 
CSS. I think we lack an equivalently easy way to do it in LC.


Not too long ago we added "behaviours" which allowed us to define a 
script behaviour and attach it to many objects. I think we could benefit 
from an equivalent  'parentAppearance' which would define the properties 
of the parent, and allow those properties to be inherited by the objects 
which specify that parent (over-riding, or rather adding to,  the 
default inheritance via the object / group / card path).


Maybe it's confusing to refer to this as 'appearance' - maybe it should 
simply be any inheritable property - I don't think those are all 
appearance related.
