Clone and "it"

[Yves COPPE]

Hi list

Something strange with "clone" command :

Mainstack A with 2 subtacks "B" and "C"

In stack "C" , a card named "Movies"
and a btn with the script :
clone player "xxx" of grp "yyy" of cd "movies" of stack "C"
answer the id of it
the answered id is good, it' s the ID of the new created (cloned) player

now in stack "B"
the same script :
clone player "xxx" of grp "yyy" of cd "movies" of stack "C"
answer the id of it
the answer is "0" don't understand...

Can anyone help me ...

thank you.



Amicalement.

RE: Opening a Rev app from a browser?

[Chipp Walters]

Doug,

Check out www.buttongadget.com and download the free trial. Then go to the
buttonsets web page and click on any picture of a button. By just clicking
on the picture, your browser will download a special stack file and launch
buttongadget and load the stack file into it.

Is that what you're looking for? If it is, I think I posted previously the
code to do this (only XP for now -- don't know how to do this on Mac)

Very cool! The first time I tried I got a "timed out" message, but the
second time I got a "welcome" confirmation back with my name.

But does this depend on a rev stack running on the server side?

Right - but if the client is logged into Server A and click on a link for
Server B, your scheme wouldn't work, would it?

Besides, if the user is logged ANYWAY, they wouldn't need this.

I see. So your idea is to keep the Client open and listening, but... how can
it be listening without opening up a socket?

No socket is open on server. Client app is actually listening in a very 
passive way, only when user click the link, server open socket and send 
for it's data, so user is online only when he is trully trying to be 
online. That way, sockets are open on client, server plays client

While we were exchanging this emails, I coded an example. It's called 
silly client.

It's available at http://public.soapdog.org/  it's a file called 
sillyclient.zip

it's a simple client. You can log into 
http://home.soapdog.org:8081/sandbox

this will show a link to check if remote user is running the client. 
pretty cool, it took me 10 minutes to do, it open no socket on server, 
and client got a vey low memory and cpu requirements.

Interesting idea - but this won't help either, for several reasons:

(1) The user can actually use this client to connect to any of many
different servers. So we have no way of guaranteeing that the user is logged
in the particular server with the link ahead of time.

(2) We wouldn't want to tie up potentially thousands of sockets by having
everybody online all the time.

If the client-side app is running beforehand there is no problem already
since all the interaction is in the client. I was hoping to just provide an
alternative way for the user to open the client by clicking on a web link,
and have the client start up, with the user all logged in.

No -I wouldn't do that. This would be a trusted app that a user has
previously, and intentionally, downloaded and set up.

Your English is perfectly fine. I didn't even know I was talking with a
non-native speaker until you mentioned it!

But what I am trying to do seems a bit different. The information you

Doug,

remember when AudioGalaxy was online and they used a combination of 
custom client and web pages? I am not here for making notes about 
piracy, copyrights and how you can screw one's life and starve artists, 
and so on, let's talk about their tech, you launched their page, and by 
that page it controlled a program running on client-side.

I just thought of it now, you can do the same with revHTTPd as long as 
the client-side app is running before the interaction begins, don't 
know what kind of interaction you want, if you want to launch an app, 
that's difficult it's like running any EXE from remote, users hate it 
and it's dangerous. But if you want your server to interact with a 
running app in the client thats easy.

Set up the client side app to listem in a default port, don't know ie: 
8084. When user log onto web page, you've got their IP, make your cgi 
try to connect to client-side app on default port and zap, interaction 
is done. That's really easy, I can set a small demo in couple minutes 
if you need an incentive! :D

But if the scenario you want it to client click a link to an executable 
program, and that program to be downloaded and run on client computer, 
then it's very big risk. Almost all browsers will not allow this 
behaviour or shout you not to do it. If you'll offer a download page of 
your client side app, and launch that app then start interaction life 
is easy. Remember satelite of audio galaxy, it was a very smart 
behaviour, their client standed still waiting for server to connect, 
that connection was initiated when user opened their web page, with a 
client running and their IP, everything is possible, you can even put 
login procedures away and acquire all info from client side app.

don't know if I am clear with this text, I am a native portuguese 
speaking person, also don't know what you're trying to do, but this 
"solution" might be used. I can code a little login demo, an simple 
client, when you open server page, the cgi on the page will look for a 
running client on client side and acquire login data. Would this help 
you?

Re: Filtering with more than 4 types (OSX) - AppleScript Question

[Sarah Reichelt]

Thanks, Sarah.

The result of the "do tScript as Applescript" can be empty, but also 
"execution
error" (if you click on the cancel button for instance).
So, I believe the test :
	if tFile is empty then return empty-- no file chosen

should be
	if (tFile is empty) or (tFile is "execution error") then return empty 
   -- no

How to detect an image or graphic deletion?

[Doug Lerner]

When I move an image or graphic, the moveControl message is sent. Similarly,
when resizing, the resizeControl message is sent.

But when I delete an image or graphic it looks like just rawKeyDown and
backSpaceKey messages are sent.

Isn't there something like a deleteControl message?

Do I just need to write a backSpaceKey handler and check and see if the
target or the selected or whatever was an image or graphic?

revHTTPd is an embedable (hell my english is horrible sometimes)

it is able to serve itself and it's substacs like they were web apps. 
You can try my home revHTTPd server and learn more about it at

with this server you can drive a Rev app in the server or interact with

you pass parameters to them with no fuss. But for a browser to launch a 
Rev app locally (at the client-side) it would be tought, it's like

FlashMX and Runtime Revolution

[Young Paik]

I'm new to the list and new to Runtime Revolution.  Wondering if anyone can 
point me in the right direction regarding FlashMX and Runtime Revolution 
integration (I'm interested in knowing how to "put" Flash into a stack and 
interact with cards).  Thanks.

 In rendering (or creating point lists) I am trying
 to use interval arithmetic and am putting that off
 until some performance changes in Revolution. 
 This method allows tests to work on
 whole zones of pixels in one calculation.
This sounds useful. Could externals helps for
these tasks?
 The line tests will be faster than the arctan2
 tests for this method, because of the ignorance
 involved in interval arithmetic. 
I've read that assembler code is faster than c code.

 In the mean time you might try testing each pixel (I
 assume you mean pixels) in the bounding rect
 of the circle of which the arc is part.
Let's see how much time does this calculation takes.


Al,

Just for an estimate of the time needed for the trial and error 
method, I ran the following handler:

on mouseUp
  put 30 into tAngle
  put 100 into R
  put "" into results
  put the sec into startTime
  startTurtle
  repeat with x = 0 to R
repeat with y = 0 to R
  put raCor(x,y) into ra
  --Test to see if the point x,y is in the wedge.
  if item 1 of ra < R and item 2 of ra < tAngle then put x,y & 
return after results
end repeat
  end repeat
  put results into field 1
  put the sec - starttime
  beep
end mouseUp

It determines all integer coordinates inside a circular wedge of 
radius R (100) and arc tAngle (30 degrees). There are 2,666 points 
and it takes a little over a second to compute.

(The function raCor(x,y) returns the radial coordinates (radius and 
angle) corresponding to the rectangular coordinates x,y.)

Hope this gives you some idea on times.

This seems odd.  I personally haven't seen this happen (maybe it's an issue
with shell) but that doesn't say much.

Two things you might try are 1) try "open process ..." instead of the shell
command, if possible, or 2) create a mini Rev "launcher" app whose sole
purpose is to launch your Word docs and then exit.  It shouldn't matter if
the mini app is affected by the shell lockup since the mini app is separate
from your app stack.

True and if some one need more explainations, i can explain how to run 
MC/Rev backgrounder (console or X11 modes under Linux, graphical mode 
under Panther) applications servers binded, one side, to Apache trough 
a PHP-based sockets listener and, second side, to PostgreSQL trough 
shell calls to psql. I'm running such apps since years (08/2000) with 
great benefits in both terms of processor's idle rate (mostly over 90%) 
and concurrent accesses requests serving (one of those servers handle 
an average of 40/60 connections/second 12/24 hours).
It is just the nature of CGI programming in general. AFAIK Rev is no 
different than other languages like Perl, Python, TCL, etc. in this 
respect.

Solution 1- Switch to an ISP than has more leniency for heavily used 
CGI apps.

Solution 2- Stop using the CGI interface and switch to an application 
server environment, which generally run in persistently in memory. 
This would mean throwing out Rev and rewriting in another language.
Sorry Alex, you are mistaking in about solution 2 : the MC/Rev engine 
is able to do lots more than the documentation describe, in about 
TCP/IP n-tier apps. I did never use it in cgi-mode (because there are 
some fine Apache modules availables for that - perl, php, python,.. - 
and because i needed, at the begining, a solution to serve flat-files 
databases over the web without having to reload the files at each cgi 
call) but as i'm, on the other hand, handling 
JBoss+Tomcat+EJB2+PostgreSQL solutions (Ecole pratique des Hautes 
Etudes - Sorbonne, cases studies only) i can assure that the best of 
the java world is not in the java's engines, but in the multilayers 
design and dev tools (Eclipe and its great debugger, the EJB's 
paradigm, UML,XML, object-relational databases mapping,...).
A modified CGI environment might be able to run Rev scripts, but most 
ISPs don't offer such services as FastCGI or PCGI.

modified CGI environment: FastCGI, PCGI
apache DSOs: PHP, Perl, Python, Ruby, etc.
application servers: ASP (.NET?), Java Servlets, Coldfusion, ZOPE.
As Apache on the webservers market or PostgreSQL on the ACID compliant 
ORDBMS one, JBoss seems to be on the right way to eat WebLogic and 
Websphere...
Hope this helps,

Non-blocking way to open MS Word files?

Hey,

I sent this message to the list a while back but never got a response. I'm
hoping this time I'll fair better. I still haven't been able to come up with
a solution on my own.

I'm writing a Windows app with Rev and need a way to open files with MS Word
from a script in my app. I've been using the shell command with the
parameter as the long path name of the file to launch Word and open the
file. This which works well except that it is blocking, meaning that my Rev
stack does not respond to mouse clicks etc. until the user quits the MS Word
instance that was launched from my script!

Does anybody know a way around this??

Any help would be greatly appreciated.

Thanks in advance,

Essentially what you need to do is write a PHP (or Perl would work)

MetaCard app takes requests and writes them back to the PHP calling 
script, and keeps on running waiting for the next request- a MetaCard

Since PHP is usually installed as a server module (rather than CGI), 
this method will most likely use much less memory. Even generally

Metacard CGI.
Just want to point out that if the ISP is balking at heavy CGI usage it 
is unlikely they are going to allow a long running server/daemon 
process.

I think you would be requiring a dedicated server or dedicated "virtual

Re: Porting PrintReport (was: Re: Windowscript)

[Stephen Quinn Barncard]

I don't know about the Report stack mentioned, but Printreport wasn't 
a collection of WYSIWYG tools, it was a programming language that 
allowed complete control of what gets printed on the page through 
graphic primitives and also allowed as complete an access to the 
mysterious apple print drivers to the point where you could exchange 
a printer configuration with the system. But it was up to the user 
how to manage it.

It was all based on text contained in the data sent to the printer 
through the XCMD. See below for a code dump generated for use by 
Printreport - Backslashes are the escape character, obviously. Tabs 
stops are handled as well as line circle and rectangle primitives and 
some insertion of pict format images. Later when color inkjets 
appeared, I was pleased to find out that the spec included basic 
color... although only through a placed graphic.

I thought that there was a later version; one that included color for text.



This is good. Two actual users of Printreport that
could answer this question:
How different is PrintReport from the stack named
"Report" that you could download from
tools.metacard.com stack?
Thanks in advance.

al

An example of Printreport code is shown below...
First is a statement of margins, then CT = tab stops, stops at 0,30 
and 85 mm, then a region is created then text is drawn inside it, 
etc, etc.

Pretty screwy, but you could do almost anything with it. I have the

No, nothing like that there. That particular "last line" variation simply
does not work for me. However, I *can*

put word 1 of the last line of field "chatField"

and see the first word.

That's why it seems like a parsing error for the

variation.

The integer math of the screen coordinates are

I had thathappen with a CGI.  I changed it so the file contains a timestamp;
if more than 10 seconds old it deletes it and moves on.

With desktop apps its more complicated, since the length of a session is
less predictable.

Could a local UDP or TCP call be used for that instead?

Try 'accept' on some obscure port.  If it fails, assume that another 
app is running.  (Immediately close any connections in the call back, 
should any be made.)  I'd try UDP first.  If you need to listen to a 
port anyway, you are set.

You could try creating and deleting a folder.  This will work faster 
than a file, I think.  If you need some temp files, anyway, put this 
where you put your temp files and put your temp files in there.  You 
may need to work out the rare case of two programs trying to run at the 
same time.

There is probably some shell command you can use.  That may work well, 
since you only need one platform.  This also needs to address the 
problems of two starting at the same time.

If you feel comfortable with two not starting at the same time, then 
you don't have to worry about that.

The openProcesses() function applies to processes opened with 'open 
process'.

Re: Scroll Bar Problem

[Rob Cozens]

Hi Glen,

I have 10 lines being continually placed "into" a field every second.

When I use the horizontal scroll bar it does not stay in the 
position I set it to...on every update it starts back in its default 
state (to the far left).

Is there a way I can have it stay where ever I place it while the 
field is being updated?
on update
  local theXLines
  lock screen
  get the hScroll of field [the target field]
  put theXLines into field [the target field]
  set the hScroll of field [the target field] to it
  unlock screen
  send "update" in 1 second
end update

Also, is there a quick way to sum the second word for the field?

function getSum
  put 0 into theTotal
  repeat for each line targetLine of field [the target field]
add word 2 of targetLine to theTotal
  end repeat
  return theTotal
end getSum

As a matter of fact, I do script resizeStack handlers rather than use the GM.

It is just the nature of CGI programming in general. AFAIK Rev is no 
different than other languages like Perl, Python, TCL, etc. in this 
respect.

Solution 1- Switch to an ISP than has more leniency for heavily used 
CGI apps.

Solution 2- Stop using the CGI interface and switch to an application 
server environment, which generally run in persistently in memory. This 
would mean throwing out Rev and rewriting in another language.

A modified CGI environment might be able to run Rev scripts, but most 
ISPs don't offer such services as FastCGI or PCGI.

modified CGI environment: FastCGI, PCGI
apache DSOs: PHP, Perl, Python, Ruby, etc.
application servers: ASP (.NET?), Java Servlets, Coldfusion, ZOPE.
Hope this helps,

RE: multiple instances of standalone under Windows

[Chipp Walters]

Hi Chris,

Not sure if this will help, but you might check out:

http://www.sysinternals.com/ntw2k/utilities.shtml

there are a number of process utilities there.

We've had some discussions on this list before, and the short answer is "not
easily." You can do things like write a file when you open and delete it
when you close --then check to see if it is there when it launches again,
but this has obvious problems.

Another idea was some sort of intra-application communication. Embed a small
server on your app and ping to see if it's around when it opens -- if true,
then you know somehthings there --still a headache.

Good luck,

best,

Chipp

A handy handler for assisting resizing, allowing you one line per object:

on ObjRect pObj
  local r,i
  put the rect of pObj into r
  repeat with i = 2 to 5
get param(i)
if it is not empty then put it into item (i-1) of r
  end repeat
  set the rect of pObj to r
end ObjRect


on resizeStack x,y
  ObjRect the long id of fld 1, "","",x-200,y-20
  ObjRect the long id of fld 2, the left of fld 1,"",x-20,y-20
  pass resizeStack
end resizeStack

Re: A Positioning Mystery

[Frank Leahy]

Rob,

When you move an object in a group, the bounding rect of the group will 
change, which is what may be affecting you.

If you have geometry on for any of the items in the group, I highly 
recommend you turn them off and do the resizing yourself.  It won't 
take much code to write it yourself, and you won't have any funny 
side-effects.  Go through each item and make sure the geometry is off 
by clicking both the "scale selected object" and "position selected 
object" buttons, and then go back and it again, because I've seen them 
stay on even when you set them off.

I did this, and I've been happier ever since.  Personally I don't trust 
the geometry at all, unless it's position by, or a line that's scaling 
horizontally.  For groups, forget it.

Good luck,

-- Frank

So it seems there is a Rev parsing bug involving "the last line" in my first

Don't think so, because that also works fine for me here. You might want 
to make sure that the last line of your field doesn't contain invisible

those won't show up.

RE: Some strange Rev parsing problem?

[MisterX]

sorry for my ranting, im having parsing problems!

Fixing things over and over for new problems is not fun.
Im currently stalled in bringing a lot of new tools for
Rev and while these pose no problem to develop and debug in MC,
RR is not as fun.

And while the GUI is definitely nicer in Rev, it's tempting to
develop on the nicer platform. Im just not getting the part where
the development part of a development system prevents clean
development. My roulette game went easy, the stupid browser was
2 times harder, buggier due to the debugger, the variable watcher
the replacetext, etc... Go figure!

;)

Note: FruityLoops is the king (like HC) of music making,
its GUI is 99% perfect and it's a pleasure to abuse...

But their patch panel channel IDE is so crappy -
but it's a beauty http://www.flstudio.com -
sorry couldn't find a picture of the channel dashboard
editor but hit the plug-ins link and you'll get the picture
of the "objects"!

I got 33 controls to create for my uc-33 (www.evolution.co.uk),
Assigning a control from the box is as simple as moving the
control on the box you need assigned! But you can't select
more than one control at a time, you can't copy-paste or cmd-d
clone, align, etc... it's a horror! But it's sweet once made!!!

If RR did midi like fruity, it could be the one and
only vst plug-in to have ;)

Re: A Positioning Mystery

[Rob Cozens]

The rect (and therefore the loc) of a group changes every time the 
visible property of a group control with part of its rect outside 
that of any other group control is changed.
Eureka!

If I ...

lock screen
show [a control whose rect encompasses all other controls in the group]
set the loc of [the group]
hide [a control whose rect encompasses all other controls in the group]
[rest of resize statements]
unlock screen
all is well.

However, I'm pretty sure the animation played a part too, as the 
animated image (after animation) has the same rect as the button 
shown & hidden above; so I'm classifying this as a double mystery:

1. The animation caused a change in the position of the animated 
image relative to the other controls in the same group.

2. When the animated image was removed from the group, the second bug bit.

...solved [or explained: I see the workaround and group locs changing 
with control visibility changes as "Mickey Mouse"] with a little help 
from my friends.   :{`)

Re: A Positioning Mystery

2. A resizeStack handler which changes the loc of the group, but 
does not address any controls in the group.
Clue 2:

The rect (and therefore the loc) of a group changes every time the 
visible property of a group control with part of its rect outside 
that of any other group control is changed.

In other words:

Open a stack with grouped controls in the Application Browser.

Click on a group name in the AB, and check its rect & loc.

Change the visibility of a group control whose left, top, right, or 
bottom coordinate lies outside the bounds of all other group controls

Click on a group name in the AB, and check its rect & loc...they WILL 
have changed.

I understand the justification of this...as far as mouse events are 
concerned, the mouse should be considered outside the group when 
outside its visible controls; however, until one understands what's 
going on, it seems counterintuitive that changing the visibility of a 
control should change the loc of the group of which it is a part.

Hi Rob,

Whie I'm not planning on playing detective inside the
Animation Builder, the one thing that crosse my mind
is : of those items are grouped, when you move one
around there's a pretty good chance that you're moving
them in positions that force the group to scroll,
causing the coordinates to change.
I would just not group any of the animated controls.

RevNet fixed

[Richard Gaskin]

Thanks to asistance from libURL meister Dave Cragg, RevNet is back in full
operation.  There's nothing you need to update - the changes were handled in
the downloaded RevNet stack.

Just choose Development->Plugins->GoRevNet as always, and you should be good
to go.

If you experience any issues with RevNet please drop me an email and let me
know.

Some years ago I designed a model and library for working with 
abstractions of drawings and paintings in a functional (that is f() 
manner) way.

In that model the plane could be partitioned by a line or by a circle 
and other shapes.  A pie shape is the union (ANDing) of two line 
partitions and a circle partition.

For this particular case, it might be easier for you to arctan2 points 
relative to the center to see if they are in the right angle range and 
then check the distance to see if that is small enough.

In rendering (or creating point lists) I am trying to use interval 
arithmetic and am putting that off until some performance changes in 
Revolution.  This method allows tests to work on whole zones of pixels 
in one calculation.  The line tests will be faster than the arctan2 
tests for this method, because of the ignorance involved in interval 
arithmetic.  Those who have never heard of interval arithmetic can 
safely skip this paragraph.

In the mean time you might try testing each pixel (I assume you mean 
pixels) in the bounding rect of the circle of which the arc is part.

I worry about whether coordinates are between pixels or in the middle, 
but I might be the only one here that does.

A Positioning Mystery

[Rob Cozens]

I've about exhausted all ideas of how to figure out what is going on 
here...anyone want to be detective of the day?

Actually, I just discovered a clue while writing this...

Scenario:

1. A group on one card of a resizeable stack, consisting of several 
images, buttons with icons, and a field. Clue: One of the images is 
moved by an animation.

2. A resizeStack handler which changes the loc of the group, but does 
not address any controls in the group.

3.  A closeStack handler that resizes the stack to it's original size.

Mystery:  Each time I open and close the stack, the position of the 
animated image changes relative to the other controls in the group.

My guess now is that the animation, which changes the size and 
position of the image, changes the relative positioning of the image 
in relation to other grouped controls as well.

Should be easy enough to test by removing the image from the group 
and positioning the group relative to the image...so I will.

But if I am correct, it seems to me this is an issue of Revolution 
features that work fine individually but start stepping on each 
other's toes when applied together.

Re: Opening a stack *behind* another stack? (take 2)

[Scott Rossi]

> How would I specify that the newly opened stack is behind another stack?

I'm not sure what the desired outcome was in this case, but here is a small
example demonstrating the opening of one stack behind another (uses a
palette stack as the main stack).  In your message box type:

 go url "http://www.tactilemedia.com/download/slider.rev";

The "drawer" stack should always open and remain behind the main stack, but
a palette style foreground stack may not be appropriate for the original
problem.

Even if that's the case, an equal sign is not really a wordy character...
Neither is a quote as far as any dictionary is concerned.

This means that you have to control the parse of any word just in case 
which is a big overhead even for a word count function - RR will get it
wrong again...

I've complained about this to Scott long ago... 

I can't remember how HC handled it but when you call a word a word
and a line a line, the least you can do is respect the language's usage...

For logic and user's sanity sake we dont need a new revolution in 
language...

And the same goes with HTMLtext display... 
I'll just say that what is not ignored (a  tag for example) affects 
the rest of 
the display (links wont display after a ) and you have to dance on 
your 
head stripping the tags and/or their parameters to get HTMLText to display 
normally... 

A new definition for the word 1g"n0r=3 I guess... ;)

Hi Doug,

Have you tried the alternative syntax for "last line",
which is to count back ?
  set the textstyle of word 1 to 2 of line -1 \
  of field "chatField" to bold

Hope this works,

   Or you could do that in one command (mind the line-wrap!):

  set the textStyle of word 1 of line (the number of lines of field 
"chatField") of field "chatField" to bold

   The two-line version is clearly preferable if you *also* do *other* things 
with the last line of the field; otherwise, which way to go is a matter of 
taste.

Hi Developers,

I'm working with geometric stuff now, and before
reinvent the wheel, i feel compeled to ask:
Do you have a function that returns all
the points or coordinates within an arc of
a circle?
Notice for a rectangular area this is
fairly easy, but an area with the shape of an
slice is another thing. Imagine how to get all the
points within a larger version of this arc shape >.
Ideas or suggestions are welcome!

Thanks in advance.

al


Al,

I presume you mean all integer coordinates within the arc. And the 
arc is a slice of pie?

This is crude, but possibly viable.

A little Turtle Graphics (with radial coordinates) might help--of course :-)

If the arc is a piece of pie: Use polar coordinates. Set the origin 
at the apex of the arc.  Test for all x-y integer coordinates within 
a square of side R (radius of the arc)  for their radial coordinates. 
Accept those for which r is less than R and theta is between the arc 
angles.

Is this clear without a figure?

But since you said yours worked I tried:

set the textStyle of word 1 of line 4 of field "chatField" to bold

So it seems there is a Rev parsing bug involving "the last line" in my first

I guess the workaround is either to use htmlText like I ended up doing or

put the number of lines of field "chatField" into nLines
set the textStyle of word 1 of line nLines of field "chatField" to bold

Duane, You will probably have more questions about Valentina than

Porting PrintReport (was: Re: Windowscript)

[Graham Samuel]

On Wed, 28 Jan 2004 12:37:12 -0800, Stephen Quinn Barncard
I'd be happier if he'd bring Printreport to the OSX world, otherwise
I'd still be using his XCMDs... actually for some stacks to difficult
to convert right now, I do and use it every day in Classic.
Even better would be to develop a library for Rev, then everybody
would be happy.
It got to the point that Hypercard was an ideal interface and glue;
but the XCMDs did most of the work.  I would often have over 50 in a
project and still have thousands of them on a CD. Too bad they can't
run in X. It's still PPC code resource - but calls the old APIs...
damn..
But Compilit! - Whoa, Tom Pittman, what a genius...maybe he could
make a cross platform XCMD generator that runs Transcript...
From what I remember of PrintReport, (I used it with SuperCard a few 
years ago now), pretty well all of the functionality could be 
repeated in Transcript, thus making it truly cross-platform. It would 
also be possible to produce a less hard-to-use interface, IMO - I 
would not personally consider trying to reproduce the interface 
itself, which is more in the style of a special language executed by 
a home-grown interpreter rather than a set of functions and 
parameters. I guess the interpreter could be written on top of the 
Transcript version for compatibility reasons, but I very much doubt 
if there would be enough customers to make it worthwhile

A limitation in the Transcript version if written today would be a 
pesky problem that has long worried me - RunRev doesn't give the 
scripter access to printer parameters, particularly the maximum 
printable area on a page; this means that it's impossible to produce 
a sensible routine for handling margins in any kind of reporting or 
printout function. When last I grumbled about this I didn't get much 
support from other listers, but it seems to me an essential function, 
and one which it must be feasible to provide for at least the Mac and 
PC platforms, judging by the various apps out there that exploit this 
information (MS Word for PC and LemkeSoft's Graphic Converter for Mac 
are two that I usually mention).

Others have pointed out that this would probably not be a commercial

Some strange Rev parsing problem?

[Doug Lerner]

Bracketing doesn't help. I've narrowed it down to an even simpler example:

set the textStyle of word 1 of the last line of field "chatField" to bold

does not work even though

set the textStyle of the last line of field "chatField" to bold

does work.

I think setting a single word chunk's textStyle was supposed to work...

Re: Filtering with more than 4 types (OSX)

[Robert Brenstein]

Since the issue of filtering has been discussed 
lately and it is pending to be fixed/improved, 
someone (Eric?) should amend the discussion of 
bug 605 to include support for more than 4 types 
(and also vote for this bug). The fact that the 
default OS procs support only 4 should not limit 
us. After all, in most other development 
environments, one simply writes own filterproc. 
We would not want that such silly restrictions 
stopped users from using Revolution, wouldn't we? 
Rev may need to write a custom proc to support 
types and extensions anyway.

Robert


Hi dreamer,

Just for information, if I remember well, MacOS 
limits the filtering up to 4 types.
A custom proc filter is needed to filter more than 4 types.

But sorry, I don't know how to do simply in Rev.
The only idea I have is to write an external 
that will call the MacOS file selector with a 
custom file proc according to your need.

Regards.
Thierry.

Bonjour à tous les Reveurs,

OSX 10.3
Rev 2.1.2
I want to display a dialog allowing the user to 
choose only pictures i.e BMP,MooV, JPEG, PNG, 
GIF and TIFF (cross platform app).
Only the four first types are considered:

answer file tPrompt with filter 
"MooVJPEGPNGfGIFfTIFFBMP " -- filters correctly 
MooV,JPEG,PNG and GIF while TIFF and BMP files 
are disabled
answer file tPrompt with filter 
"PNGfGIFfTIFFBMP MooVJPEG" -- filters correctly 
PNG, GIF, TIF and BMP while MooV and JPEG files 
are disabled

Any idea to by-pass this apparent limitation?

Mille mercis par avance !

Re: Checklist for getting an app ready for distribution?

[xbury . cs]

I use the explicit variables in MC which find probably 80% of all 
bugs due to misnamed variables, send messages not formated
correctly... Again, this is a great feature I praise for solid scripts...

Check every menu feature from left to right... Or from feature priority
down... Up to you...

Then I give my stack to my mom and she'll do the weirdest things a user 
can
do trying to figure it out and show me about another 50% of errors or 
unclear
features ;))

Another way is to write down the feature list before doing the stack and 
then
checking each one after... Keep a log and check continually. Most 
important
is to recheck after the stack is finished to make sure any last mod doesnt 
affect
previously working scripts... This is lengthier but it's very solid...

I don't know if it's relevant, but several times I've had the
same problem with long expressions, and solved it by putting
parts of the expression into brackets, for instance :

set the textStyle of (word 1 to 2 of the last line of field "chatField" of
stack "chat550") to bold

Another problem might be that "word 1 to 2" can't be used when
setting props, only for retrieving data (get word 1 to 2 of...).
In your example, I would rather use :

repeat with i=1 to 2
   set the textStyle of word i of the last line of field "chatField" of \
   stack "chat550" to bold
end repeat

Checklist for getting an app ready for distribution?

[Frank Leahy]

Hi,

Does anyone have a handy list of things they do before they get a 
product ready for distribution?  Or maybe even a little stack that 
checks a bunch of stuff automatically?  For example, check that fields 
don't have a font and font size set by mistake.  That the stack has a 
font and font size set.  Get a list of which items have colors set 
(could have been set mistakenly for example).  Those types of little 
things as well as any bigger things one should be aware of (such as 
cross-platform issues).

Thanks in advance,
-- Frank

Re: XMLlib does not parse

I am new to XML and try to use rev to read a PAD file. I have a
problem where the revCreateXMLTree function does generate this error:

quite often used, why then does rev not know it?
I don't think Rev's xml parser is the only one 
that doesn't handle Windows-1252 encoding. But 
you're right that it should support it.

As a temporary workaround (until support is 
addded) you could try changing the encoding to 
ISO-8859-1 before using revCreateXMLTree. The two 
encodings are not identical, but they might be 
close enough for many uses.

For example (assuming the xml data is in the tXML variable):

  replace "Windows-1252" with "ISO-8859-1" in tXML
  get revCreateXMLTree(tXML,false,true,false)
Note that this is a crude example for 
illustration. Apart from the encodings not being 
identical (Windows-1252 has additional characters 
to ISO-8859-1), the above script assumes that the 
text being replaced only occurs at the top of the 
xml data. A more "robust" replace function is 
probably necessary for serious application.

export the screen to an invisible image (or to a variable and then to

Thanks, Sarah.

The result of the "do tScript as Applescript" can be empty, but also "execution
error" (if you click on the cancel button for instance).
So, I believe the test :
if tFile is empty then return empty-- no file chosen
>
should be
if (tFile is empty) or (tFile is "execution error") then return empty-- no
file chosen

Re: Filtering with more than 4 types (OSX) - AppleScript

[Éric Chatonet]

Your script for filtering with more than 4 types (OSX) with AppleScript 
(Vol 4, Issue 189) works fine :-)
Many thanks.
When "MooV" is among the filters, then all types recognized by 
QuickTime are displayed : moovies, images and sounds as well!
I do regret this!
Due to system and QT?
