Re: Retrieving Date and Time From The Internet

[stephen barncard]

 I thought it could be done directly with a time server, and one can!
I did some dicking around with sockets and made this up.

this uses the Daytime Protocol
(RFC-867)

function returnNISTime

  -- returns UTC time in RFC-867 (Daytime) format

  -- sqb @ the house of cubes

  put "time-C.timefreq.bldrdoc.gov:13" into pServerURL

  set the socketTimeoutInterval to 1000

  open socket to pServerURL

  write "" to socket pServerURL

  read from socket pServerURL for 49

  put it into a

  put the result into b

  close socket pServerURL

  delete line 1 of a

  return  a

end returnNISTime


--

put returnNISTime()


returns:


55790 11-08-17 04:57:45 50 0 0 102.3 UTC(NIST) *


note that everything one needs is here, including the year.

This clock data is read directly from a source that is mission critical and
cannot go down.


THe only caveat: if you are on a LAN then you must open up port 13 on the
router

OT: Slideshow Image CMS Best Practice

[Sivakatirswami]

I am using Galleria on our web site.. (galleria aino.se)
I love it... so extensible, customizable, documentation is excellent

I've written some .irev libraries that only need a path to a folder with 
images and adjacent matching text files for captions and then LiveCode 
dynamically builds the slide show web page. It's simple. I have a 
desktop client that people use to create content:


someImage.jpg
someImage.txt  # a caption file

this CMS is really very portable and can be massaged into any kind of 
delivery framework...


I'm just wondering what others think in terms of future CMS and coding 
and issues.  A fork in the road:


1. ALL IMAGES IN ONE FOLDER (thumbnails, 800px wide "large" photo, 
1500px wide "Big Photo"

-- with file name appendages

/centipede-gallery
/images
mother-centipede.jpg #800px wide
mother-centipede.txt# caption
mother-centipede_thumb.jpg #100px wide
mother-centipede_big.jpg  #1500px wide

OR

2) USE Separate Folders AND file name appendages

/centipede-gallery

/images
mother-centipede.jpg #800px wide
mother-centipede.txt# caption
/thumbnails
mother-centipede_thumb.jpg #100px wide
/big
mother-centipede_big.jpg  #1500px wide

Galleria documentation is agnostic (as it should be) but "kinda" points 
to all images in the same folder:


as flat HTML:

div  id="gallery">




or as JSON:

A common misconception and the source of endless problems in applications which 
share data from multiple computers or are run all over the world due to the 
different ways people worked out how to make use of the extra 128 combinations 
that are available (MacRoman, ISO-8859-1, ISO-8859-2,etc and, not forgetting, 
the myriad of Windows Code Pages.

It is just not possible to distinguish between a two consecutive single-byte 
chars and a double-byte char, after all they are just combinations of 16 bits. 
To handle any text, you need to know how the text is encoded. If you haven't 
read http://www.joelonsoftware.com/articles/Unicode.html you probably should. 
It even mentions Bulgaria!

It would be interesting if someone did a "Basic Programming" course for 
the whole planet, using LiveCode.


I think Devin Asay is well positioned this.

We have a new young recruit here at the monastery.

I sent him all the URLS for Devin's materials a the BYU site, for LiveCode.

I think so. Updating the code so that only line 1 of sDataArray[theIndex][pKey]

Notice that some years ago, someone post in this mail list
a stack, where you type text ina field and a script replaced the
letter with an image.

The principle is similar with vector graphics. You just need to store
the vector data somewhere in a stack.

If all you need is the modified date/time of a file from an FTP site, the
MDTM command works well.

put libURLftpCommand("MDTM " & pathToFile, tFtpServer, tFtpUserName,
tFtpUserPassword) into tMDTM
answer tMDTM

The commands like LIST, RETR, etc. that need an open socket won't work with
this form.  Commands which perform an action such as renaming a file work
well, and return a simple result string.

I wish there was a get the detailedFTPfiles command in LC.

Re: ASCII, Unicode and Livecode

[Bernard Devlin]

If you get the htmlText of a char in a unicode mixed field (i.e.
containing single & double byte chars), there is an attribute of the
 tag that tells you the font.  If you get char 1 of a double
byte char, that font attribute of the paragraph tag will (in my
experience) contain "unicode" as item 2 of the font.

Thus, try "put the htmlText of char 1 of fld SomeUnicodeField into msg".

That at least allows one to detect if a char is unicode or not, even
if one only gets hold of one of the two bytes that make up the char.
I think this is the simplest (albeit clumsy) way to detect the nature
of a char in a run of mixed text.

You could try this:

http://www.worldtimeserver.com/current_time_in_CA-QC.aspx

Your time info is here in the html it returns (example):



5:10 PM



Tuesday, August 16, 2011


Eastern Daylight Time (EDT) -0400

Isolate this from the rest of the source and filter out the lines that begin

just select one

A fun challenge.  Here's one option, limited to a single time (US Eastern),
with no guarantee of reliability (can any Web-based service truly claim
this?):

function timeStamp
   put url "http://www.atomictime.net/front.html"; into temp
   wait 500 millisecs with messages

The reason for the dual URLs is the host requires initial access through a
home page.  Only thing I can guess is there's some back-end foolery going on
that's not accessible (at least I can't see anything that's apparent, but
maybe that's just me).

I tried setting my system clock back 2 hours and the page continues to

delivery chain, a number of emails to 'quartam.com' were delayed, going back as 
far as July 22nd, 2011.
Having just 'liberated' those emails, I am working my way through them now. If 
you are still awaiting a reply, do not hesitate to resend it to this yahoo.com 
email address, or the regular quartam.com email addresses, or both.

My apologies for any inconvenience, as a result of the delays caused by this 
mishap.

Thanks, I will build the stack here. I isolated the problem to a carriage
return character in one of the records. The \n character mess up the theData

Re: Double byte trouble

[Mark Schonewille]

Hi Richmond,

I wrote this yesterday already. The availability of byte and char indicate that 
RunRev is aware of this problem. Unfortunately, RunRev hasn't actually taken 
action to solve it yet.

For now, it is just a fact that fields who have the unicodeText property set, 
need two bytes for a character and will return only the first byte of a 
character when you retrieve char 1 of that field.

That said, have you tried getting char 1 of the text of fld x? Does that help?

Andre,

Cant you send me a single stack with a single data grid in it that has the
data causing problems? I should be able to determine the problem based on
the problems you found thus far.

Re: Double byte trouble

[Bob Sneidar]

I'm going to say that if you were to delete the first char of a 2 byte unicode 
char and then put more unicode text after it, things would not go so well, but 
I am just guessing.

Double byte trouble

[Richmond Mathewson]

I did this:

set the useUnicode to true
set the unicodeText of fld "INN" to numToChar(69)

and, unsurprisingly, an 'E' appeared in fld "INN"

when I then did this:

delete char 1 of fld "INN"   'E' vanished; again, unsurprisingly

when I put a spot of unicodeText in my fld "INN"
the "delete char 1" script MADE THE FIRST UNICODE CHAR vanish.

If that is so, why do I have to refer to double-byte unicode chars as 
"chars 1 - 2"

folks, for anyone following this thread, to try to script the rev stacks,
you can break your IDE or introduce real problems. I am doing this because I
have a backup of Trevors original stack, so I can play and if I break

Re: [HELP] Facing a datagrid bug

Update

the sortByKey function calculates a variable theData that is used to compute
the sorting. This variable had a leading CR here in some cases and thus
broke the functions after it. Deleting that line made things work.

I think the bug goes deeper than that. While I solved the drawing problem, I

Malte,

Thank you. I for one would love any Unicode library any one cares to post.
Currently Unicode in LiveCode is one of the technology items that requires a
LOT of fussing with to get anything to work.

I'd also ask Kevin (RunRev) to please consider posting an update on the new
Field object and "Unicode that just works" as we approach the end of Q3 2011
next month. The guestimated time frame for 5.0, the version that will
hopefully contain the new field and Unicode support, was suggested as late
Q4 2011 or Q1 2012. As Q3 2011 comes to an end in September, some update
would really help those of use who have product development plans tied to
that next LiveCode version (or at least the features we hope will be in it).

Re: Retrieving Date and Time From The Internet

[Bob Sneidar]

Okay, I contacted the USNO site via email and requested that they include the 
year in the returned date/time. 

I have a modified script which includes the year, but I caution you that the 
convert command is getting the current year from the system if it is not 
supplied, which defeats the whole purpose of getting the Real Time. We are 
still at the mercy of the system date and whatever the user sets it to. 

Until someone can come up with an HTTP link that returns the year with the date 
and time, or else Livecode supports NTP queries, we are SOL. I have searched 
high and low and cannot find one single web site besides 
http://tycho.usno.navy.mil/cgi-bin/timer.pl that returns anything usable. Leave 
it up to a sailor to get you most of the way there, and then let you swim the 
rest of the way! LOL! (I'm an ex-sailor so I can say that). 

function realTime theFormat, useOffset
   if useOffset is empty then put false into useOffset
   put "http://tycho.usno.navy.mil/cgi-bin/timer.pl"; into theURL
   get url theURL
   put it into theResult
   filter theResult with "*UTC*"
   replace "" with empty in theResult
   put word 1 to 3 of theResult into theResult
   put word 4 of the internet date into theYear -- bummer relies on system 
datetime
   
   if useOffset then
  put word -1 of theResult into theTime
  put word -1 of the internet date into theZoneOffset
  put theZoneOffset /100 into theZoneOffset
  set the itemdelimiter to ":"
  put (item 1 of theTime + theZoneOffset) into item 1 of theTime
  put theTime into word -1 of theResult
   end if
   
   put space & theYear after word 2 of theResult
   
   if theFormat is "seconds" then
  -- not entirely accurate as it returns the same value with the year
  -- as it does without it, leading me to believe the convert command 
  -- is accessing the system datetime to get the year if it is not provided
  convert theResult to seconds
   end if
   
   return theResult
end realTime

put the cUTF8Text of field "ContainsMixedChars" into tUTF8

-->  UTF8 is double byte only when needed and things like the itemdel

put "aoi" after tUTF8

set the cUTF8Text of field "ContainsMixedChars" to tUTF8

ASCII, Unicode and Livecode

[Richmond Mathewson]

So, there I am reading a BBC computer manual (as one does) where I am
informed that the ASCII set consists of 128 chars . . .

. . . that's funny, because I had 256 (i.e. 2 x 128) rumbling around in 
my mind.


As I have to develop a script that determines whether a char is a 
single-byte char or the first half of a double-byte char . . . ouch . . 
. this is probably fairly важно, to use a rather useful Bulgarian word . . .


Messing around in Livecode, I set up a stack with 2 fields; one 
containing a string of ASCII text:


"LAT" Еat my cheese

and the other containing a Unicode string:

"UNIK" 'a Sanskrit word' I won't try to represent here [anyway, a spot 
of juicy double-byted goodness]


then I set up a third field called "C1"

2 buttons; one to get the charToNum for the first char in fld "LAT", and 
one to do the

same for fld "UNIK"

they both contain this sort of script:

on mouseUp
put charToNum(char 1 of fld "LAT") into fld "C1"
end mouseUp

and that's all very jolly, except that

on mouseUp
put charToNum(char 1 of fld "UNIK") into fld "C1"
end mouseUp

returns "9" which is within the ASCII range, so there is no way I can 
use that sort of script to determine what I want to.

I'm not sure if your setup will allow it, but the actual delivery date

Re: Retrieving Date and Time From a Remote Computer

[stephen barncard]

Wouldn't it be better to get time data from a place that's mission-critical
consistent, like the NAVY and WWV? Then you wouldn't have to maintain it or
deal with outages.

Hi Bob,

No, just my office Mac a few kilometres away.  I was thinking of other ways of 
not relying on the date and time settings of users who would FTP data to me.  
If my client app can grab the date and time from my office make, then I have a 
consistent timestamp that I can rely on.

Re: Grabbing the Date and Time From a Time Server on the Internet

[Gregory Lypny]

Hi Bob,

Good summary, Bob.  It summarizes nicely the issues that I’m dealing with in 
creating a client-side student helper app.  Your RealTime function works 
nicely.  The only thing missing is the year, which again, is something that a 
user could set manually.

I've added the following code to the data grid library:

## Default is not to pass in value for pIndexes to draw in which case
  ## we use the base sequence for visible controls to determine indexes
to draw
  if pIndexesToDraw is not empty then
 put itemOffset(item 1 of pIndexesToDraw, sIndexSequencing) - 1 into
theSequence
  else
 put item sTableObjectsA["base sequence for visible controls"] to \
   (sTableObjectsA["base sequence for visible controls"] +
sTableObjectsA["row control count"] - 1) of sIndexSequencing into
pIndexesToDraw
 put sTableObjectsA["base sequence for visible controls"] - 1 into
theSequence
  end if

## AAG: Below I fix a possible bug
  repeat while char 1 of pIndexesToDraw is not a number
 delete char 1 of pIndexesToDraw
 if pIndexesToDraw is empty then
exit repeat
 end if
  end repeat


With that in place, everything starts working.

I think I found it. When sorting ascending, the pIndexesToDraw variable
which contains a comma separated list of indexes, has an extra comma like:

 ,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18

So it fails. I think I might have uncovered a bug somewhere

Re: [HELP] Facing a datagrid bug

[Bob Sneidar]

I am going to say that there are characters in the text that Livecode does not 
expect. But I am guessing. You can try a divide and conquer approach to test 
this. Start by creating two globals. Put half the data into one global and half 
the data into the other. Populate the dataGrid with one half, try to sort. If 
it fails, divide that in two. Rinse and repeat. 

Eventually and before too long you are wither going to find out what the 
offending data is, or the problem will persist proving that it isn't an odd 
character in the data. 

Also, would you mind sending me a stack with the datagrid complete with the 
data? Let's see what happens here. If it's reproducible, it's pandemic. If not, 
it's local. 

Bob

Re: [HELP] Facing a datagrid bug

[Bob Sneidar]

You can override everything about the datagrid. Copy the behavior script to a 
button in your own stack:
set the behavior of button "myBehaviorButton" to the script of the behavior of 
group "dgMyDataGrid"

Then set the behavior of your datagrid to the new button:
set the behavior of group "dgMyDataGrid" to the long ID of button 
"myBehaviorButton"

Now you can make the datagrid pop up grumpy messages every time you sort like, 
"I'm not in the mood." or "You sure are bossy!" if you like. :-)

I have been updating a pdf manual for my LiveCode application which I created
with Screensteps Pro.   It is such a great product.  I had to redo many
screen shots since I had some UI changes.   Piece of cake.  I also decided
to rearrange the order of the sections in the manual and move sections
between two different manuals.  No problem. 

If you are new to LiveCode and haven't yet heard of ScreenSteps you should
try it out.   It is created with LiveCode.

Re: Retrieving Date and Time From a Remote Computer

[Bob Sneidar]

Remote as in a different time zone?? If they are both set to query a time 
server, then the remote mac will ALWAYS have the same time as the local one. If 
it is always in the same time zone, calculate it. 

Apart from that, I suppose you would have to ssh in which means setting up 
firewalls (ick). Or else you would have to set up some kind of server that 
could be queried, but still firewall issues.

Re: Using the Detailed Files Function to Get Info From a Remote Machine

[Andre Garzia]

Gregory,

You can't access remote machines unless they have an FTP server or something
similar or you can mount their volumes as a disk. If you mount the remote
machine volumes, then you can use the detailed files but I think that
appleshare file sharing only works on LAN.

You best option would be to use:

libURLSetFTPListCommand "LIST"
put url "ftp://myserver/files/";

I think LIST is the default choice, so you should already see something
similar to the detailed files. If your remote mac has no FTP server enabled
and it is not on LAN with File Sharing enabled, then unless you have
something running there, you can't get a file listing.

The sorting routines just use the built-in sort command in LiveCode. My
guess is it chokes on the unicode data. I don't think it will choke on UTF-8

You can.

Using the Detailed Files Function to Get Info From a Remote Machine

[Gregory Lypny]

Hello everyone,

Can the Detailed Files function be used to get file information from a remote 
Mac or am I limited to the listing provided by put url (“ftp://...”)?

Gregory

[HELP] Facing a datagrid bug

[Andre Garzia]

Folks,

I am consistently facing a strange bug with the datagrid in 4.6.x in more
than one project. I don't have an exact recipe but I can explain how it
works. I have a datagrid that mimics a table. I am just placing text in
there. Some text columns will have content on just some fields and this
content may have some unicode characters such as accents of some symbols
such as that superscript "o". When clicking the column header to sort the
column, the datagrid will display an dialog box saying error in the script
and die. This happens just for some columns but it is happening in three
projects. It is really hard to debug but I believe it is related to the
routine that sorts the datagrid, I think that down inside that function,
some comparision command fails and the error bubbles up from there.

Anyone seeing something similar?

This is happening here in three different projects all related to database
frontends. I have a card with a list of records. When for example I click
the header of column "Title", it will fail and die. I don't know why. The
datagrid should not fail like that. The array used is a really big one maybe
a megabyte or two worth of information. It is basically text but it may
contain unicode characters. I am using that unidecode trick from the
documentation, the data appears fine in the datagrid.

Also, why can't we override the sorting routines?

Cheers
andre

iOs - images from the foto library

[Malte Brill]

Hi all,

out of academic interest I would like to know if it is possible to set the 
filename of an image to an image resource in the photo library? I guess due to 
the sandboxed nature of iOS apps, the answer is no, but I'd better ask before 
speculating... As far as I can see the only way is mobilePickPhoto "library" 
and then use the imported image, right?

Cheers,

Malte

hmm, very strange indeed!

I never use "snapshot" with a player anyway, since I use Trevors wonderful 
"Enhanced QuickTime External" to export a movieframe to disk:


At least worth a try! :-)

AW: Lion snapshot trouble (was: Lion trouble with quicktime) please confirm

[Tiemo Hollmann TB]

Hi Klaus,

thanks for testing, that didn't do the trick for me, I get irregular
results, the more often I do testing.
I think I found the reason what has changed with Lion. It is related to the
alwaysbuffer property of the player. Setting it to true in my test app did
the trick, but doing the same in my real app, I still get a bluescreen as a
snapshot. Setting it permanently to true, I can't even play videos anymore,
the player object keeps bluescreen too.
Something must have changed with Lion, because my standalone runs fine on
Leopard, but not anymore on Lion.

Confirmed, I get an empty image instead!

But this snytax does work:
...
  Put the rect of player 1into tRect
  Export snapshot from rect (the rect of player "foo") of player "foo" to file 
"export.png" as PNG
...

Lion snapshot trouble (was: Lion trouble with quicktime) please confirm

[Tiemo Hollmann TB]

Ok, I made some more test and the problem doesn't seems to be related to
quicktime, but to the snapshop function on Lion.
I tested with LC 4.6.3 on Lion with the following code:

Put the rect of [image | player | button] "foo" into tRect
Export snapshot from rect tRect to file "export.png" as [PNG | JPEG]

Exporting a snapshot of an image or player object (with assigned image/video
file) results in corrupted image data (stripes, black,...)
Exporting a snapshot of a button works fine as expected.

Could anybody please confirm this as a bug or point me on what I am not
seeing?
Thank you

To me the key is to have your class members identify a number of small
'real' problems that you filter to those you know that LC can quickly solve.
These might take YOU anywhere from 1 - 6 hrs to solve. You might also
discover that a couple of problems fall into the same category, like text
parsing - my favourite ;-) It might then be possible to work with the class
as a whole to solve one problem, then assign homework to apply their new
found knowledge to solve the other.

As an example, I'm interested in buying a second hand car, and I visit two
websites to check out what's available. It's a hassle flicking through the
pages and trying to remember how many kms the 2005 model for $14,990 had. So
for each site I've created a script that takes the data and scrapes it for
only the info I'm interested in: model, year, kms, number of owners,
transmission, price. The data is then stored in a db from which I can group,
compare and order the cars so that I can figure which appear to be better
value for money.

As for lesson 1, I reckon a 100% chance that someone will have a text
manipulation problem so after discussing what people want their computer's
to do, I'd cover how easy it is to work with text in LC. Simple stack, two
fields - one to enter data, the other for output. Start with a button, but
eventually go with 'on closeField'. Show them how they can extract the
first, second, last and char/word/line 24 from the field. How they can add
or remove char/word/line. How char/word/line can be rearranged. If the text
happens to be a list, how they can be referred to as items. How if the data
has any form of consistency, then extraction of specific data is easy; this
can be because it's always on line x, it's always word y, it's always the
word before 'kms', or are the chars immediately after $ - you can avoid grep
and still find the data, that's the great thing about LC. But if you spark
someone's interest, you can always teach them a grep solution too :-)

And just to give you my personal favourite, I'd teach them the switch
statement.

switch (tInput)
   case ("yes")
  hYesHandle
   break
   case ("no")
 hNoHandle
   break
   default
 answer "An answer I wasn't expecting" title "Case Error!"
breakpoint
end switch

I hated nested if-then-else statements which can be extremely hard to
understand, so unless I'm 100% certain that it's yes/no, true/false, or 1/0
, I always use a switch statement similar to above - with the default set to
tell me I'm missing something followed by a breakpoint. As soon as I get a
"maybe" input, I'm prompted that I need extra code, presented with the
Script Editor exactly in the handler where the extra code is needed and the
Variable Pane showing what's in tInput so I can immediately figure out why
the script didn't proceed as expected. For newbie programmers this can save
a huge amount of time wasted (read - turn you off programing frustration)
trying to figure out why the outcome is wrong.

Good luck,

Re: Ideal Unicode?

[Richmond Mathewson]

"Ideal Unicode'

Will never exist for a few simple reasons:

1. Unicode is a moving target (the Unicode commission keep producing 
updated versions).


2. Computers and computer operating systems are moving targets.

If one is prepared to invest one hell of a lot of time (and I have) 
poking around in Livecode one can do almost everything with unicode; 
admittedly often in a cumbersome and counter intuitive sort of way.
