Hi Howard

I've written an external for iOS. It's a bonus when you buy mergZXing my iOS 
barcode reader external. See http://goulding.ws/merzxing

Cheers

Re: MP3 Tag Editor

Glad it worked out. I didn't check the stack I linked you to, I thought it
had specs on the stack, like libJson.


Who put Mark's ON-rev site back up? I thought it disappeared.Or is he
an on-rev pioneer with a forever plan?

yes I too was impressed with his strict adherence to specs in all his
stacks.

Thanks Stephen!

The Late Mark Smith? Hmm I missed his transition...
Hope he is well after stepping through The Big Door.
Or perhaps he will come back soon and be join the next generation of 
LiveCoders.


I got it... fantastic... and for those looking for documentation  I 
found this in the archives:


http://marksmith.on-rev.com/revstuff/files/

and the

id3Lib.zip  

contains documentation. I recall now I used his UUID functions years ago.

Looking at ID2.org  is an eye opener... some incredibly awesome options and it 
looks the Mark's
functions cover all frame options defined to date.

saving lyrics with the song could be a real plus.

Re: standalone not quitting on Win7

Hi Mark,

> That script looks familiar :-)

Thought it might be yours. Knew it couldn't be mine -- somewhat over my head!

And you were right. Now, after I removed the database drivers from
Externals on my nonWin7 machine, the standalone won't close there
either. Will verify this on my Win7 once I get home from work.

Thanks!

Re: standalone not quitting on Win7

[Mark Schonewille]

Hi Nicolas,

That script looks familiar :-) Do you do any error checking in your standalone? 
If, for example, you're not including database drivers, revOpenDatabases() will 
cause an error and your app will not quit. You need to adjust your script a 
little by removing the irrelevant parts.

standalone not quitting on Win7

[Nicolas Cueto]

Hello,

A standalone can quit on pre-Win7 but not on Win7.

Here's the relevant scripts for the card and the stack:

on closeStackRequest
   lock messages
   -- MySql
   put revOpenDatabases() into myDatabases
   repeat for each item myBase in myDatabases
  revCloseDatabase myBase
   end repeat
   -- stop using stacks
   put the stacksInUse into myStacks
   repeat for each line myStack in myStacks
  stop using stack myStack
   end repeat
   -- stacks
   put the openStacks into myStacks
   put "message box,home,tool,Message Box,revTools,revMenubar" & comma
& the short name of me into myDontClose
   repeat for each line myStack in myStacks
  if myStack is not among the items of myDontClose then close stack myStack
   end repeat
   -- messages
   put the pendingmessages into myMsgs
   repeat for each line myMsg in myMsgs
  cancel item 1 of myMsg
   end repeat
   set the backdrop to none
   unlock messages
   if the environment is not "development" then
  pass closeStackRequest
   end if
end closeStackRequest

on closeStack
   quit
end closeStack


Any ideas?   Thanks.

Bizarrely, once you've got your HD in the sidebar you can navigate to your

To permanently reveal the ~/Library folder, in Terminal:

There is on the desktop, but I don't know about iOS… on the desktop you'd add a 
custom URL protocol to the info.plist file of the standalone by adding this 
inside the first  tag (I'm using a fictitious "MyApp" application here):

CFBundleURLTypes


CFBundleURLName
MyApp URL
CFBundleURLSchemes

myapp

LSIsAppleDefaultForScheme




This would cause the MyApp application to launch whenever the url "myapp://" 
was executed. Not sure if this works on iOS, but perhaps you could try it?

Re: Find nearest color in an RGB list

[Nonsanity]

Both look like good suggestions for getting the closest color a human would
think is a "match", but both involve converting Livecode's native RGB to
another format. I may be wrong, but I don't think those conversions are
available built-in. I'm sure functions have been written to do this many
times, but it's not trivial to do from scratch. If you can get one, then
the following code will still work - It'll just work better. (Replace the
r, g, b variable names with the appropriate letters for clarity.)

Depending on your use case, you may not need to be that human-accurate, in
which case you can do the same calculation in RGB space. The square root
calculation in your two solutions is a way to get the distance between any
two points in three dimensional space. All three color formats have three
values, so they can all be pictured as a cube of space with colors as
points within that space. Your starting color is in there too, and you just
have to check the distance from it to all the other color points, and
return the shortest.

I'm typing this in a mail program, so it is untested...

function Distance3D( x1, y1, z1, x2, y2, z2 )
return sqrt( (x1-x2)*(x1-x2) + (y1-y2)*(y1-y2) + (z1-z2)*(z1-z2) )
end Distance3D

function GetClosestColor( r, g, b )
put 9 into ClosestDist
put r &"," g &","& b into ClosestColor
repeat for each line c of gColorList
get Distance3D( r, g, b, item 1 of c, item 2 of c, item 3 of c )
if it < ClosestDist then
put it into ClosestDist
put c into ClosestColor
end if
end repeat
return ClosestColor
end GetClosestColor


You'd have your colors in gColorList like this:
32,32,128
255,255,255
0,0,0
128,128,256
(etc)

Re: OS X Lion

[Marty Knapp]

Pete -  Use the "Go" menu in the Finder, while holding down the option 
key - that makes it show in the menu.


Marty

A while back there was a discussion on the changes in access privileges to
some directories in Lion, I believe mainly to do the system Library
directory.

Yesterday, I went through the process of installing an LC app on Lion for
the first time, and also experiencing Lion for the first time.  I don't
need to access the system Library directory but I do need to put a
Preferences file in the user's Library/Preferences folder which I assume is
still the place for preferences files to go.

Pre-Lion, I would just click on the icon for my Home directory, then
navigate to Library/Preferences in the Finder.  In Lion, I could not find a
home directory icon to click on, nor could I find an icon representing the
computer's hard drive, either on the desktop or in any Finder windows that
I could see.

I should say I do not have a real installation process for this app, it's
something I put together quickly for a friend, so I was simply copying
files from a CD to his computer.  We didn't have much time to do the
install so I wasn't able to poke around Lion to see if there is a way for a
user (a System Admin user of course) to get to the Library/Preferences
folder.

Hopefully someone can give me some guidance on this.  I'm also left to
wonder if my application will be able to access the preferences file even
if I manage to put it into /Library/Preferences.

Thanks,

Re: Sorting Advice

[Pete]

Hi Marty,
I'm not too familiar with the sort command but it sounds like you could use
the each keyword and write a custom function to return the concatenated
values of items 1 and 2 (zero padding item 2 so you could sort works on
text), thus sorting in 1 pass.   I have no idea whether it would be any
quicker than two passes.

Find nearest color in an RGB list

[Michael Doub]

I have a list of RGB colors that represent different color samples.   I need to 
create a function that will return the closest perceived RGB entry in the list 
when supplied a single RGB value.  Is anyone aware of a library or some sample 
code that would help with this task?

>From searching I found the follow two suggestions for solving this problem.  
>Neither are not intuitively obvious to the casual observer...namely me. ;-)


1) "Convert RGB to  CIE Lab color space, then compute the distance in that 
space ( deltaE = sqrt(deltaL^2 + deltaA^2 + deltaB^2).  Colors with the lowest 
deltaE are the most perceptually similar to each other."

2) "Convert to RGB to HSL and consider an HSL color value a vector and define a 
weighted modulus function for the vector like this:
modulus = sqrt(a*H1*H1 + b*S1*S1 + c*L1*L1);  where a,b,c are weights you 
should decide based on your visual definition of what creates a bigger 
difference in perceived color - a 1% change in Hue or a 1% change in 
Saturation.  I would suggest you use a = b = 0.5 and c = 1 Finally, find out 
the range your modulus would take and define similar colors to be those which 
have their moduli very close to each other (say 5%)"

Regards,
   Mike

I've been effectively locked out for quite a while now. It won't even 
recognize my password any more, and resetting it didn't work. I have a 
bug report, which has been confirmed, but it doesn't specifically 
address user contributions.


Anyone else having issues may want to add comments:

I can confirm that Rev Online is down here, too. So are the user comments in 
the Dictionary in the IDE. IIRC they are on the same server. I've sent a note 
to support asking about it.

Re: Sorting Advice

[Marty Knapp]

OK, so I'm good. Just though I might be missing something. Thanks Stephen.

Marty

I think one has to make multiple passes - the doc say for "sort container":

*The sort container command is a stable sort. This means that if the
sortKey for two items or lines is the same, sorting does not change their
order, so you can do two successive sorts to create subcategories within
the major sort categories.*
*
*
* Tip: To create a custom sort order, use the eachkeyword to pass each line
or item to a custom function. The valuereturned by the function is used as
the sort key for that line or item. Note that it is not currently possible
to debug custom sort functions, and doing so could make the IDE unstable.
It is recommended to use logging messages instead.*
