Wow, that's fast.  So I decided to compare it to an implementation of Dar's
second suggestion, which I've been using for a long time. The test I tried
yields times very different from Richard's.  Even though my machine is a
dual 2 GHz G5, function "Shortlist" took almost a hundred times longer than
Richard reported.  I wonder why the times are so different.
But the other function ran almost 70 times faster than function "Shortlist."
Indeed it did. My earlier test was bunk -- can I use jet lag as my 
excuse today?  :)

Here's the latest test below -- the array version is indeed orders of 
magnitude faster.

But one note from Ken raises a question -- Ken wrote:
Unfortunately this is something that will be executed in a
loop several thousand times, so even at 25ms * 2000 that
ends up being 50 seconds, which is way too long.
You've probably already consider this, but is there a way you can reduce 
the number of iterations?

Editing standalone

[Cornelia Brunner]

I am an education researcher building little applications for non-commercial
uses (not a programmer) and I have I have just done a really stupid thing
and replaced my folder with the original .rev file in it with a folder
containing the standalone (Mac). Now I need to edit the application but I no
longer have the .rev file. Is there a way to re-open the standalone inside
Revolution? I would greatly appreciate any help, any work-around that lets
me get back inside the application without having to start all over. And I
HAVE learned my lesson!

It's certainly possible; there were some problems in earlier versions

If you want to give it another try, let me know off-list what the 
problems are (or, probably better, join the Pythoncard mail list at 
http://lists.sourceforge.net/lists/listinfo/pythoncard-users  and if you

e.g Example exists so name new entery to Example(2), Example(2) exists so

any ideas woold be appreciated thanx.
 

Here's a simple function (and test script - you need a field "inField"

local lList = "ss, tt, ss(1), ss(2),"   -- start with some values 
already there
on mouseUp
 put field "inField" into t

QT player question

Hello all -
I expect this is an easy question, but I can't seem to see how to do 
it!How do I see if a player is playing?

The playrate property always returns 1 (I want to play movies at normal 
speed) I had thought it might return "0" if the movie was not playing.  
The movie() function only seems to work with video clips, not player 
objects.  So I can't say "if the movie is done..."

I need the equivalent of a "playing()" function that would return true 
or false.

If the application is writing to the console instead of to stdout,

Watch very hard :-)
The playrate property always returns 1 (I want to play movies at

The playrate determines the plaback speed of your movie and 0 means 
that a playing
movie is currently paused ;-)

I had thought it might return "0" if the movie was not playing.
The movie() function only seems to work with video clips, not player 
objects.  So I can't say "if the movie is done..."

I need the equivalent of a "playing()" function that would return true 
or false.
Since there is no direct way to dtermine what you want, use a little 
trick:

function movie_is_playing
  put the currenttime of player xyz into ct
  wait 10 millisecs
  return (the currenttime fo player xyz < ct)
 ##will be true if the movie is inded playing, else will be false
end movie_is_playing
Here i just check 2 different "times" and see if they are identical or 
not...

Hope that helps...

Cornelia,
I don't know of any way of opening the stack once compiled. You may at 
least be able to recover the text in fields and custom properties and 
perhaps even some of the scripts by opening the application bundle 
(appName>Contents>MacOS>StackName) in a text editor like BBedit, or 
even in a web browser or in MS Word.

[ANN] #012 How-To stack: Asking password

[Éric Chatonet]

Hi everyone,
How-To stack #012: Asking password
Shows how to ask a password in a customary field.
Usually, the job is done using 2 fields, one of which is hidden.
Here a custom property stored in the field is used as a substitute for 
the usual 2nd hidden field.
This way makes it easy to copy/paste the scripted field into any stack 
where it will work immediatly :-)

This algorithm assumes that every item in the exclusion list is

either list, and that both lists are in ascending numeric order:

Re: Python and Rev

[Joel Guillod]

Anybody familiar with Ruby or WideStudio?
Personnaly I use Eclipse + PyDev + Ant + wxDesigner for GUI (I am 
trying it currently) + wxPython (i.e. a wrapper for the wxWidgets as 
the multiplatform GUI). At first a bit more complex than Revolution or 
RealBasic IDE but opensource, much more reliable and quick fixes by the 
wide developers' community, object oriented with more complex data 
structures and many important modules ready to use (xslt, database, 
sockets, easy C/C++ externals, ...). Like others I will probably keep 
Rev for some programming but the most important - and the most 
difficult - is to use the right tool for the right thing...!


Rev allows AppleScript via the "do ... as AppleScript" command.
Perhaps this could be extended to support things like
do ... as Python
do ...
Why not? But under MacOSX 3.x you just have to run the following script:
  put "print 'hello'" into thePythonScript
  put shell("python -c " "e& thePythonScript & quote)
(also similar for ruby...).

Detecting the stack that have the mouse pointer

[Alejandro Tejada]

Hi Developers,

I have a mousemove handler in
a frontscript. 
This mousemove handler puts the X,Y
position in the message box and i want
to know the mode of the stack over which
the mouse pointer is.
Toplevel stacks have a mode of 1
palettes, modeless stacks and modal stack
have different numbers.

for example:

i expect that when i move the mouse over
a stack, appears in the message box:

35,79 stack "mytoplevelstack" mode 1

or

10,10 stack "myCustomstack" mode 2

How could i do this without clicking on
the stack?

Thanks in advance.

One way is to replace your mouseMove handler with a looping script that
checks every line in the openStacks.  Something like:

 on checkMode
  put the openStacks into tList
  repeat for each line L in tList
if within(stack L,the screenMouseLoc) then put the mode of stack L
  end repeat
  send "checkMode" to me in 50 millisecs
 end checkMode

You also might be able to limit the check to a few stacks.

Can't you just say:

  put the mode of the mouseStack

??

I tested it this way - put this script into a button:

on mouseUp
  CheckIt
end mouseUp

on CheckIt
  if the commandKey is down then exit CheckIt
  if the mouseStack <> "" then
put the short name of the mouseStack && (the mode of the mouseStack)
  end if
  send "CheckIt" to me in 50 milliseconds
end CheckIt

Click the button, and start moving over different stacks - you should see it
change accordingly. Hold down the Command key to make it stop.

It's not "faster" or "slower". The earlier comparison compared two 
functions - "Shortlist" and "difference". "difference" is the code that 
uses arrays and delete variable - i.e. the second of the suggested 
methods from Dar, and also suggested by Monte.

Combining the previous stats and the new one, (i.e. extrapolating and 
guessing) you get something like
old Shortlist : 300
new code (and variants) : 200 + / - a bit
difference : 15

i.e. all the methods that loop through making use of the fact that the 
data in each list is sorted are significantly faster than using "among 
the lines of", but much slower than using the arrays.

Given the problems with that one, I'm curious: how does something like 
this compare (this version only requires that both lists are in 
ascending numeric order):

looks like just another variant - I'm guessing it will be 200ms give or 
take a bit, and don't feel the need to know exactly how much plus or 
minus; the array method is clearly the one to use.

Thanks a lot Scott and Ken

My oversight of the mouseStack
only means that i've not used
this function before. 

But it's very useful for recreating 
an interface in RR/MC.

There is no doubt. I have to practice
more frecuently this area of development,
(along with sockets, cgi, binary data
reading and writing, game programming,
databases, customproperties sets, etc...)

Shrinking Mac stack

[J. Landman Gay]

I am still having the problem where the bottom of a stack gets cut off 
on Mac standalone builds when the stack contains a menu bar. This has

The way I avoid this issue is to place the menu in a substack and reference
it from there.

If anyone's interested in making their plugin 'altPlugin compatible' 
they can check out:

http://www.altuit.com/webs/altuit2/altPluginCover/CreateyourownPlugins.htm
The advantage of using altPlugins is the ease at which you can release 
updates w/out having to put any update code in your plugin.

For those who are wondering what an altPlugin is, it's just any old 
stack, which can open with a click of the mouse. AltPlugins can reside 
anywhere on your hard disk, or if you drop them in the altPlugs folder 
(contained in the plugin folder) they are auto-added to the toolbar.

More about them can be found at:

Anything we might addrress in the Rev interoperability initiative?

Sounds like a great idea! Jerry Daniels will soon be releasing a whole

I bow to your experience.
In that case, I'd look for a way to keep sets in the db in a form that 
is handy for their use.  If use is primarily set operations, I'd look 
toward optimizing that, and choosing the representation for that 
optimization.  I think that leaves out an array as representation.

Precisely. The growing number of tool suites in the Rev community is 
what led to the creation of the RevInterop initiative.

Currently each toolkit uses its own method of identifying the info 
needed for updates, integration, etc., but if we could take the time to 
draft one universal standard then all tools could ideally be fully 
interchangeable without futher modification.

The initial rought draft identifies a number of common elements needed 
by all plugins, including author, copyright, URL, and more.  Since most 
of these types of data were already identified by Dublin Core, we've 
light-heartedly adopted the name of "Edinburgh Core" for these properties.

That initial rough draft and a sample library stack with placeholder 
properties are available at:


All input from plugin developers is appreciated.  No such initiative can 
be useful in a vacuum. :)

That depends on how you write the queries, how busy the server is, how 
much information needs to be shuttled between the client and the 
server, and various other factors.

Also, an ad hoc query against an SQL server needs to be parse, planned, 
and executed by the server each time it is sent.  A complex query may 
be better handled as a stored procedure, so that it can be pre-planned; 
this will cut down on execution time later on.  If you are dealing with 
a large amount of information, processing it on the server may cut down 
on time spent transmitting info across a slower network which will 
later be eliminated anyway.  Additionally, depending on the operations 
being performed, the server may be able to take advantage of indexes, 
etc. that the client will not have access to.

Now as far as using the SQL server to maintain lists, if you can store 
each entry as a separate row in a table, for example (based on 
PostgreSQL and untested; may or may not be the most efficient queries 
in some cases):

CREATE TABLE myLists
(
listID INTEGER NOT NULL,
listValue TEXT
);
CREATE INDEX ndxMyLists ON myLists (listID, listValue);

Now to retrieve a list in sorted order by value:
SELECT listValue FROM myLists WHERE (listID = 1) ORDER BY listValue;
To perform an intersection operation between two lists:
SELECT DISTINCT listValue FROM myLists WHERE (listID = 1) AND 
(listValue IN (SELECT listValue FROM myLists WHERE (listID = 2

To perform a union operation between two lists:
(SELECT listValue FROM myLists WHERE (listID = 1)) UNION (SELECT 
listValue FROM myLists WHERE (listID = 2))

**or**
SELECT DISTINCT listValue FROM myLists WHERE ((listID = 1) OR (listID = 
2))

To perform a set difference:
SELECT listValue FROM myLists WHERE (listID = 1) AND NOT (listValue IN 
(SELECT listValue FROM myLists WHERE (listID = 2)))

Note that this set difference is only different from my suggestion for 
intersection by a single NOT operator...

I missed the original post, what else did you need to be able to do?
BTW, one of the issues with using mySQL like this is its lack of 
support for stored procedures, or have they added this capability yet?  
Even pure SQL stored procedures would be fine for most of this stuff...

Re: Shrinking Mac stack

[Chipp Walters]

Hi Jacque,
Hope this helps:
(from an earlier post:)
For those of you who've come lately to this, the problem was simple. How 
to add menus for both Mac and PC to an existing stack *without* ever 
resizing the existing stack.

As you all probably know, the minute you add a menu to a stack, it's 
height is recalculated whenever it opens on a different platform. The 
reason is that the menubar is 'on the card' for the PC, but at the top 
of the screen for the Mac. So, when viewing the stack on the Mac, the 
stack is automatically reduced in height by the amount of the menubar 
(thus screwing up my carefully rendered screen layout;-).

bummer, especially if you don't want this behavior.
So, Richard's idea was pretty straightforward:
set the editmenu property of the stack to true
hide the menu group
So, here's how it works: When the stack is opened up on the Mac, because 
the editmenu prop is true, the menus appear at the top of the card and 
not in the menubar. But a little known fact (only Richard knows it 
apparently as it's not documented) is that the menus will appear in the 
menubar if the menuGrp is hidden! So, just hide the group and then show 
it if the platform is Win32.

Works like a charm...and no resizing of the stack whatsoever.
Cool, and thanks Richard!

If the DB is properly indexed, there is no way that Transcript should 
be able to perform that kind of sort faster than the DB server.  An SQL 
server should be able to use an index to perform that kind of sort 
substantially faster than it could be done by a generic sorting 
algorithm, such as what Rev would need to use with its 'sort' command.

The only major exception is when the client is distributed among 
multiple computers (different people accessing the server 
simultaneously with the client on separate machines per user) and the 
database server is on hardware which is being very heavily used.  In 
this case, the client may be able to sort the incoming data faster than 
the DB can, only due to the server being slowed down by a heavy 
processing load of multiple other users.  However, there would need to 
be a rather extreme number of users for a correctly indexed database to 
slow down to this point, at least with a query like that one, since the 
index should allow the server to just read off the needed data in a 
sorted order to begin with, rather than needing to take any extra steps 
to sort it at all.  Complex views might complicate the matter somewhat, 
but last time I checked, MySQL did not support views (a somewhat 
strange omission for such a popular db server...)

Re: How to get the difference between two lists?

[jbv]

I must confess that I'm much more fluent in Transcript than in
SQL, so productivity-wise, I feel more confortable writing
complex transcript than complex SQL...
Nevertheless I'm working on a project involving a table with
23,000 entries (so far) and 35 fields in each (total weight 5Mb)
that makes heavy use of indexes. I have SQL requests involving
at least 5 to 7 fields, that extract 12 to 20 flds, and on which I
perform successive sorts.

for instance :
SELECT A, B, C, D, E, F, G FROM myTable WHERE A>10 AND B>A AND H>G
etc...

the selection can reach 1000 to 1500 lines

and then :
sort lines of myRequest ascending international by item 6 of each
sort lines of myRequest ascending numeric by item 5 of each
sort lines of myRequest ascending numeric by item 4 of each
sort lines of myRequest ascending international by item 2 of each
etc

and then further processing, like grouping lines in which item 1
contains similar values to be displayed in different tables in a
HTML page and / or comparing values of item 6 of each line with
a set of values already stored in a field of another table, etc.

then build (rather complex) HTML pages by reading template
txt files and replacing certain kew words with HTML code build
in the same script around data from the db...
---

I didn't perform any speed test, but the general feeling is that cgi
requests are performed significantly faster when most sorting /
processing is done in Transcript than in SQL...

I also have a client web app (made with Rev) that accesses the
same db / server, and the feeling is the same...

I hadn't seen this in a while but not more than 10 minutes after 
reading this I noticed this on an app we are testing right now.  I 
don't see it on my development computer but it does happen on another 
computer here at the office.  So the bug is still alive and well.

In the case I'm looking at right now the card height is reported 
correctly and my controls resize to the visible size of the stack but 
the bottom 21 pixels of the stack are just white (my graphics/controls 
are cut off).  When I switch to use the stack height to resize controls 
then my controls resize just above the 21 pixels that are white.

So it would appear that Revolution is displaying the window equal to 
the height of the card but only drawing controls into a height equal to 
the height of the stack.

Re: How to get the difference between two lists?

[Brian Yennie]

I'm sure all of this is application specific, but generally speaking if 
you are pulling data from MySQL and _then_ sorting it in Transcript 
faster than in-database, there is probably something non-optimal about 
the database schema or queries. Generally speaking, when I'm working on 
a web application that needs to handle a lot of hits, it's a huge red 
flag if I have to post-sort anything out of the database. That's not to 
say Rev can't take the wheel and do a pretty good job (kudos to Rev), 
but I can't remember an instance where I couldn't make more of an 
impact working on the database side of things.

With that said, if it's a factor of needing to do _other_ things in Rev 
at the same time, programming efficiency, etc- then it's a perfectly 
fine solution.

I would be shocked to find that Rev is better optimized for sorting 
than MySQL in any general sense. I'm wondering if it's worth pulling 
out any more specifics that someone can share about their table 
structures, queries, etc?

Please note I don't mean that sorting should literally be offloaded 
back to the database- but that there is almost always a fast way to get 
it that way in the first place, especially if we're just dealing with 
recID lookups and sorts.

Re: Table Field

[zack]

Sorry,

I would like it to display like a spreadsheet, With columns and rows
appearing in the cells Instead it is just displaying in one long string.

The fields are delimitated by TAB and the records are makes with a RETURN.

Field1  Field2  field3
etc etc etc

But when put myVariable into field "my Table field" I get one long string.
It is not split up into the cells as I expected.

Is Rev looking for different delimiters?

You need to set the properties of the field to behave like a table.  
You can do this using the "Table" page of the Property Inspector for 
the field, or (assuming you have Rev 2.5 or newer) you can simply drag 
out a "Table Field" from the toolbar rather than an ordinary "Field" 
(the Table Field icon is right next to the Field icon).

You can control column widths using the tabStops property, which is 
also available from the Table page of the Property Inspector.

Copying a background from one card to another *duplcates* the

the author intends for the background to be shared so that changes 
to the background made from any card will be reflected in all other 
cards on which the background appears. To make that happen, the 
group must be set to behave as a background.
Actually, this isn't so - a group can be shared without having its 
backgroundBehavior property set to true. Shared groups worked fine 
even before the backgroundBehavior property was added to the 
language. What backgroundBehavior does is cause shared groups to be 
automatically placed on new cards, as well as tweaking the message 
path for the group so it matches HyperCard's behavior more closely.

(My only excuse for not documenting that "place" turns on 
backgroundBehavior is that no one told me about the change, and I 
didn't stumble across it on my own when the property was added. If I 
had been told about it, I would have argued that it was a bug, not a 
feature. Commands shouldn't spew side effects like that, even if 
they're documented. As it is, apparently if you want a shared group 
whose backgroundBehavior property is false, you need to remember to 
reset the property after every time you place the group on a card.)

The whole situation with backgroundBehavior is confusing. It was 
added in order to better emulate HyperCard backgrounds, which it 
does, but there were collateral changes (for example, changes to what 
"the backgroundNames" means) that resulted in, IMHO, a mess.

Toggle Listbehavior

[Sivakatirswami]

I want to toggle the listbehavior of a fld with a simple check btn:
on mouseUp
  set the listbehavior of fld "ToDo" to the hilite of me
end mouseUp
problem: it works to set listbehavior to true but
unchecking leaves "orphaned to true props" :
locktext  ## remains set to true
dontwrap  ## remains set to true
is this a bug? If setting listbehavior to true turns these properties 
on, then should they not be turned off if they were not on in the first 
place? The following is of course a simple work around, but I was 
thinking perhaps there was an issue with setting listbehavior to false. 
Or is this expected behavior...

on mouseUp
  put "locktext,dontwrap,listbehavior" into tProps
  repeat for each item x in tProps
  set the x of fld "ToDo" to the hilite of me
  end repeat
end mouseUp

Re: Toggle Listbehavior

[Brian Yennie]

Sivakatirswami,
I think what you are finding is that these properties are only "linked" 
by means of the Rev IDE. They are in fact totally independent, it's 
just that the IDE emulates certain types of "canned" objects by 
sometimes locking multiple properties together.

As such, your workaround is actually the proper use, I believe.

It doesn't seem like a bug to me. The listbehavior can't work without 
both locktext and dontwrap also set; if they aren't set, you don't have 
listbehavior. However, both locktext and dontwrap can be used 
independently regardless of listbehavior, so I think it makes sense to 
leave them on when listbehavior is turned off.

I took a break and tried my hand at this.
The function using offset did better than array element deletion in 
some cases.  The function using replaceText() did poorly for medium 
size lists and bailed out for large lists to be removed.  I think there 
is something fishy (that is n^2) in replaceText().  The last one was my 
attempt to avoid 'line n' and is similar to Frank's, I think.  It was 
still a little bit slower than array element deletion in my tests.

function shortListDar2 pList, pExcludeList
  local resultList = ""
  put lf before pList
  put 0 into lastUsedChar
  if char -1 of pList is not lf then put lf after pList
  repeat for each line ex in pExcludeList
put lf & ex & lf into exWithLF

if it is not zero then
  put char lastUsedChar+1 to lastUsedChar+it of pList after 
resultList
  put lastUsedChar + it + length(exWithLF) - 1 into lastUsedChar
end if
  end repeat
  put char lastUsedChar+1 to -1 of pList after resultList
  return char 2 to -2 of resultList
end shortListDar2

  put lf & "10" after pExcludeList
  put line 1 of pExcludeList into checkLine
  put 1 into charOffset
  repeat for each line listLine in pList
repeat while checkLine < listLine
  add length(checkLine)+1 to charOffset
  put line 1 of (char charoffset to charoffset+20 of pExcludeList)
