Re: arrays with merge

[Terence Heaford]

Also tried it with one space after array as

put merge("SELECT [[tColumns]] FROM '[[tTable]]' [[myArray["test”] ]] 
[[tSortOrder]]") into tSQL

Still got a syntax error.

LC 6.7.5 Mac.

Is there a solution?

All the best

Terry

Re: arrays with merge

Did this and I still get a syntax error.

put merge("SELECT [[tColumns]] FROM '[[tTable]]' [[ myArray["test”] ]] 
[[tSortOrder]]") into tSQL

Any ideas

Thanks

Method 1: Turn it into a 2-liner:


put myArray["test"] into tTest
put merge("SELECT [[tColumns]] FROM '[[tTable]]' [[tTest]] [[tSortOrder]]") 
into tSQL




Method 2: Have the entire string to be merged already stored elsewhere:


put merge(the uSQL of me) into tSQL

or

put merge(url "file:sql.txt") into tSQL


where the custom property "uSQL" or the file "sql.txt" already contains the 
string:

SELECT [[tColumns]] FROM '[[tTable]]' [[myArray["test"]]] [[tSortOrder]]



Method 3: Use a function to represent an array:


local myArray -- make sure this is outside both handlers

function myArray pString
   return myArrayTest[pString]
end myArray

on doStuff
   -- some stuff here
   put merge("SELECT [[tColumns]] FROM '[[tTable]]' [[myArray(test)]] 
[[tSortOrder]]") into tSQL
   -- more stuff here
end doStuff


This last method works as long as the name of the key ("test" in your example) 
isn't a LiveCode reserved word.


Hope this helps! :)

Small typo:

myArrayTest[pString]

should of course be:

myArray[pString]

Re: arrays with merge

[Ali Lloyd]

Hi,

The reason
put merge("SELECT [[tColumns]] FROM '[[tTable]]' [[myArray["test"]]]
[[tSortOrder]]") into tSQL

doesn't work is  the double quote around "test". Merge should work fine
with arrays (I should know because bug 11274 was one of the first I ever
fixed!)

You can either use & and quote to build the correct string

put merge("SELECT [[tColumns]] FROM '[[tTable]]' [[myArray[" & quote & test
& quote & "]]] [[tSortOrder]]") into tSQL

 or put "test" into a variable beforehand

local tTest
put "test' into tTest
put merge("SELECT [[tColumns]] FROM '[[tTable]]' [[myArray[tTest]]]
[[tSortOrder]]") into tSQL

Ali

Re: arrays with merge

[Terence Heaford]

Interestingly it works without quotes around test.

It does work but should it?

This suggests the only reason for quotes in array keys is in case you have a 
two word key?

put merge("SELECT [[tColumns]] FROM '[[tTable]]' [[myArray[test]]] 
[[tSortOrder]]") into tSQL


All the best

Re: arrays with merge

[Ali Lloyd]

Yes, that is LiveCode 'unquoted literal' mechanism -

It is the same as, for example, (if you have strict compilation off)

*put* tTest & "sdfsdf" -- puts tTestsdfsdf into the message box


When a variable has not been declared, any tokens that are not keywords are
treated as strings.

Re: Clock

[BNig]

Roger,

this is probably due to the limited processing power of the android-watch

This is similar to iOS back when I made the scrollers. At the time iPhones
had trouble mixing all the blend modes fast enough.
So I build in a cheat. The command is "makeiOSReady" it is located in the
script of the group. What it does is to make a snapshot of the scroller and
hide all the graphics. What is left on is an image "mock" and layered on top
of this field "fDisplay-Scroll"

For the first 3 of the clock faces try

on mouseUp
   dispatch "makeiOSReady" to group "Hours"
   dispatch "makeiOSReady" to group "Minutes"
   dispatch "makeiOSReady" to group "moveSeconds"
end mouseUp

once you are done with your resizing of the groups because a resize of the
group, e.g. "hours" will remove the image "mock" and you do your resizing on
the graphics.
That is the reason why you issue the "makeiOSReady" command at the end, when
you are done configuring the groups.

This should put considerably less burden on the processor of your
android-watch.

If that does not make it work try disabling the card script that set the
color.

Also you may play with the wait x milliseconds with messages that is issued
twice, once in mouseUP handler and once in "advanceSeconds" handler of the
start/stop button

send "setWheel tHours + 1" to  group "hours"
send "setWheel tMinutes + 1" to  group "Minutes"
send "setWheel tSeconds + 1" to  group "moveSeconds"
  
  wait 5 milliseconds with messages  -- increase the milliseconds to
wait, gives more time.

What I see in the video is very much what took me long to debug and which
turned out to be the wait... being too short.

Note, "makeiOSReady" only works on the non-egg shaped scrollers. For
egg-shaped scrollers I could look into them next week when I am back from a
weekend trip and see if I could tweak them to work more efficient. But there
is a lot of computation going on behind the scene.

Try these suggestion in the given order and see what makes it work. Please
tell us if you get it to work.

Kind regards

Bernd

Re: arrays with merge

[Mike Bonner]

As ali said, the unquoted key is only an issue if there is a declared
variable, at which point the key becomes whatever is in that variable. (or
if its a keyword of course)

I use the "store the string elsewhere" method.  When creating merge strings
for later use, I either create them using the property inspector, or put
them into a field and set a property to the field.

The other option mentioned is pretty helpful.  Put in an unquoted key, and
set the value of it as a variable.  This can be pretty handy because you
can change which key you want to look at on the fly.

The things that I would most like to add to livecode would be strict
compilation being the default, absolute case sensitivity (unless turned off
for comparisons), and strong typing of variables.  Oh, and c-style variable
scoping.

Fully understood. I know you have a bug/enhancement report on this.
What is the status from LiveCode?


Very good new on the Windows front:  somewhere between the last time I 
tested and now, #5886 appears fixed; both currentTime and startTime work 
well in v7.0.5 under Windows 8.1 - many thanks to Panos Merakos at 
RunRev for taking the time to follow up on this one.


   "'start player' ignores currentTime w/dontuseQT"
   

It would be helpful if anyone here has time to test that under Windows 7 
or 8.0 to confirm there are no remaining issues with those versions either.


While reviewing player-related bugs I was also able to confirm that this 
report submitted by another member here is apparently also fixed:


   "Revolution plays WMV files unreliably"


Trevor's comment #4 there notes the engine was using the deprecated MCI 
interface at that time - might that have changed since then?


I tested WMV, MP3, AIFF, and a few other formats, and they seem to play 
well in v7.0.5 under Win 8.1.


I was also unable to reproduce this one, though again it would be 
helpful if others here have a chance to test under Win 7 or 8.0 to confirm:


   "Movies on network volumes can't used with player object"
   


Unfortunately the most popular codecs do not work in 7.0.5 under Win 8.1:

   "Support mp4 and h264 without QuickTime"
   

Still, good progress on the Windows side, and hopefully those codecs can 
be supported without much effort.  The MP4 files I tested with play well 
in the Windows Media Player app, so we know the OS includes the codecs 
needed.



As for Linux, the crasher I reported has been confirmed:
   

I haven't heard anything from the team directly, but the activity on 
#5886 suggests that they're reviewing at least some video issues, and we 
know that crashers tend to get priority.


With any luck, once the crash is resolved we'll be able to make sure 
currentTime and startTime work as well on Linux as they do on Mac and 
Windows now, and with that I'll be able to do what I need with video for 
now.

The 'formattedText' property of a field is a string so the expression:
  the textFont of word 1 to -1 of the formattedText of thFld

Does this:
  T1 = evaluate the formattedText of thFld
  T2 = word 1 to -1 of T1
  return the textFont of T2

Now, because T2 is also a string, the engine tries to interpret it as a 
control reference.


If you want to access properties of the styled text of the field, then 
you need to do so directly on the field itself:

  put the textFont of word 1 to -1 of field thFld

As an aside, you also cannot use 'exists()' on font names - it is only 
for control references. Instead you can use:
  (the textFont of word 1 to -1 of field thFld) is among the lines of 
the fontNames


Hope this helps,

Mark.

Simple .lc Script to INSERT data...?

[JOHN PATTEN]

Hi All,

I must be missing something simple and I can’t find it…

I have a mysql database with one table and one field. Varchar(1000)

I have a LiveCode project with one button and the following code:

on mouseUp
   put urlEncode(the name of target) into tName
   put "object_name=" & tName into ArgList
   --answer ArgList
   post tArgList to URL "http://username.on-rev.com/ipad_1/add_data_2.lc";
end mouseUp


My .lc file looks like this:



The .lc script creates a new record but it never puts the name of the button in 
the object_name field? The record is completely empty.  I was having the same 
problem on a much more complex database and script, so I thought I would super 
simplify but I’m still having the problem.

Does anybody see anything I’m missing?

Thank you!

Re: Simple .lc Script to INSERT data...?

[Matthias Rebbe | M-R-D]

John,

if you post data to a livecode server script then you need to use $_post[] 
instead of $_get

$_get[] is used if you add the parameters to the url like

put  URL ("http://username.on-rev.com/ipad_1/add_datga_2.lc?object_name=“ & 
tName) into tResult

Regards,

Matthias

Re: Simple .lc Script to INSERT data...?

[JOHN PATTEN]

Thanks Matthias,

I did try both ways $_POST and $_GET.  I get the same results; a new record is 
created but the fields are empty.  By the way, the "LiveCode Cloud" tutorials 
show $_POST for inserting new record too.

I’ll keep looking :)

Re: Simple .lc Script to INSERT data...?

[Mike Bonner]

You're putting your data to post into ArgList
And you're posting tArgList

If thats not a typo here, I suspect its the typo culprit there.

Shouldn't it return "empty" then?

OK, I see that's better (I had to go to formatted text at some point
because something else wasn't working.  Or maybe that was before I focused
on words.  I think it was when I was trying to null out the textSize &
textFont of the pasted text to force it to use the field's settings)

(oh, and thFld was actually an id, not a field name)

exists() entered late while debugging it.
word 1 to -1 of  theFld
did it

But I'm still troubled by this plowing through over 150 fields before it
found one it didn't like this on . . .

Re: LiveCode 8 and a new video player?

[Kay C Lan]

This is probably thread drift but video playback is so 20th century.

I had an old acquaintance pass through town and we caught up. He's working
for a start up that's doing something similar to Google Glass. He had a
demo unit to show me. The googles worked with any users phone (or iPod
touch) but of course it was the software that was on show.

He first showed me some 3D games, a roller coaster, etc. Very cool, but I'm
not into games but even I can see they'll make a $illion. I was much more
impressed with the 3D Paul McCartney concert. I could turn around and see
the thousands of fans behind me. I could look up at roof of the stadium, I
could even watch the show. There were even shots taken from on stage, so
again I could look out to the crowd, watch each and any of the musicians or
even Sir Paul himself. My choice. My friend then removed the cover over he
camera lens and then showed me a demo of Augmented Reality (AR). If you
don't know what AR is here's a mediocre demo:

https://www.youtube.com/watch?v=EhTcAvbjwjg

So the basic requirement is that screen is filled with whatever the camera
is seeing, and then there is some 2D image which triggers something else to
be played on top of that 2D image whilst the rest of the screen continues
to show the real world. In the demo I was shown, I was handed a 2.5" cube;
with the naked eye on each of the six sides was a different, simple black
and white line art image. With the phone and the software (the goggles
aren't necessary, but when used it becomes immersive) I had a 3D animated
miniature horse in my hand. As I rotated the cube I could see the walking
horse from any angle; not just the left side, then the right side, then the
bottom etc, but as I slowly rotated the cube the horse also very smoothly
rotated: 45°, 13°, 76.1345° it was very smooth and very cool and everyone
else in the restaurant were still eating their dinner.

He said someone was working on a Harry Potter style game of chess. All the
pieces would be just basic rectangular prisms of appropriate size and
proportion, but every single side would have a unique image, thus every
single piece when viewed through AR device/software would be alive and
unique. Castles would have archers firing arrows from the battlements,
Knights would have individual armour both for them and their horses. Pawns
would be individual foot soldiers, uniformed alike, but still unique and
with personality. Another $illion there.

Now I'm not suggesting that LiveCode needs to be at the forefront of 3D
multimedia and AR; there is no way the next 3D Grand Theft Auto will be
written in LC; this is the territory of dedicated game houses. Obviously 3D
is all the rage, but it doesn't have to be. I've seen some very basic 2D
uses of AR, especially in the real estate industry. A prospective buyer
notices a for sale sign outside a house, or sees an add in the
newspaper/magazine, simply by holding up the mobile device (with
appropriate app installed) to the sign/add, a gallery of 2D photos becomes
available, of every single room of the house, plus views outside the house
from multiple angles. Buttons appear so you can immediately phone or email
the agent; no need to actually read it off the sign/add.

In the 21st Century I see AR as being huge. I don't know what technology is
required to make it work, even on the most basic level, but whatever it is,
LC needs to jump aboard. HyperCard bought us Myst, I'm sure there are lot
of very bright people out there that have very unique and niche ideas on
how AR could be leveraged to bring static objects to life - museums, art
galleries and libraries immediately come to mind. It would be nice if LC
made that easy to happen.

I hope someone is going to tell me, 'oh we could already do that... if only
startTime worked' ;-)

Re: "breakpoint" gets edited out of cut/paste in IDE?

[Kay C Lan]

Defintely not!

I use hard breakpoints almost exclusively and copy and paste scripts from
one object to another within the same stack as well as to different stacks
altogether on a regular basis and I've never seen this.

I'm currently on OS X 10.9.5 LC 6.6.5 and 7.0.5 but I've been copying and
pasting scripts with breakpoints from the Rev 2.0 days and have never
noticed this ever happening. I just did a quick test in 2 new stacks in
7.0.5 and had not problem copying a script with a hard breakpoint across to
the other stack.
