Eventually, a successor for HyperCard?

Me too, as a DreamCard user (and former HyperCard then MetaCard user) I
was sent areminder from Revolution -- and I wonder was to do...

Also, I don't understand the purpose of "or update your Dreamcard
license for one more year." since there is NO more update!

Re: Read from StnIn from POST is still broken?

[Pierre Sahores]

Hello Katir,

I did'nt have the opportunity to test this for a while but what works  
100% fine (we went spoken about before if i right remember) is to  
stick a PHP sockets listener in front of your Rev CGI script or Rev  
backgrounder stack based app. A very reliable way to do Rev able to  
support very heavy write-mode transactions traffic. After height  
years in using this design, i never had a socket brokken in only one  
of my running production's apps. At this time, i just know that 800  
connections/second is the top-stressed level one of my apps has  
sometime to support and, in this situation, all worked always as  
expected without any "accident" (Athlon XP Pro 800, 1Go RAM, Suse- 
Linux from september 2000 to september 20005 - Mac OS X 10.3.9, 1Go  
Ram, G4 box since september 2005).


See as a reminder of the second way to go, the "paper" and  
downloadable example app at , my little xDSL test and home mac mini server.


Kind Regards,

Pierre

Re: resizable stack with Mac unresizable with Windows

I didn't test this in 2.7, but in earlier versions there used to be a

Since you're including all default decorations plus metal while there

Right. There's the point. When you buy something like Hypercard, or

like a parameterized PowerPoint. The feature-comparison page on the

on Windows parts of text printed repeatedly instead of once

[André . Bisseret]

Hi !
In the app. I am developping, each card includes several fields 
(author, title,  texte, références). In a printing procedure I wrote a 
function (formatfldToPrint) that picks the texts of these fields (with 
their htmlText) and arranges them as a single document in a hidden 
field « fldToPrint » (not all with the same font and size).


Thanks to the Dan Schafer’ SmartEBook on printing I have improved my 
first draft and the following script is working very well now on Mac :


 on imprimer
  set the cursor to watch
  formatfldToPrint
  set the printmargins to 72,25,25,50
  revShowPrintDialog true,true
  put tab & "Page " & "<%pageNumber%>"  into footer
  revPrintText (the htmlText of fld "fldToPrint"),,footer
  reset cursors
end imprimer

But I got problems when testing on Windows. I hope I will solve several 
of them thanks to insights I collected on the Mail Archive, but I did 
not find anything on the following problem :


For a document that is printed on 2 pages with Mac, I get 7 pages with 
Windows. With Windows, the text is repeated something like 5 times.


Not sure I will be enough clear because it is difficult to explain 
(especially with my english, not really fluent :-((, but well, I am 
doing my best :-))


On the first two pages, the text is printed only up to a certain line 
(near the end of the text) then, reprinted, but starting from a certain 
line in the middle of the text up to the end, then, again, reprinted 
from another line in the middle of the text up to the end, etc (4 
times).


Moreover, on the first page, last line is crunched and on the second 
page the first one is also crunched ; it is the same line (same 
content) that appears as if it has been cut in two slices( in length), 
the upper slice printed at the bottom of page one (juste before the 
footer) the inferior slice printed at the top of page 2.
This slicing does not appear again on the following pages (3 to 7) that 
begin and end normally.


I cant imagine why such repetitions are occuring ??

I would much appreciate if someone could help me understand this 
phenomenon ? (and of course better along with a suggested solution :-).


Best regards from Grenoble

Re: The End of Dreamcard?

[Stephen Barncard]

Close. 19 years ago. I remember it came in the box with the new SE20 
for A&M studios. I was attempting to build an app with Z-Basic at the 
time, and not getting anywhere...then discovering this thing.. 
what's this... some kind of add-in hardware card? ha ha


From Wikipedia:
HyperCard was created by Bill Atkinson and initially released in 
August 1987, with the understanding that Atkinson would give 
HyperCard to Apple only if they promised to release it for free on 
all Macs. Apple timed its release to coincide with the MacWorld 
Conference & Expo in Boston, Massachusetts to guarantee maximum 
publicity. HyperCard was a huge hit almost instantly.


Many people who thought they would never be able to program a 
computer started using HyperCard for all sorts of automation and 
prototyping tasks, a surprise even to its creator.


Apple itself never seemed to understand what HyperCard was. 
Management saw that it was being used by a huge number of people, 
internally and externally, and bug reports and upgrade suggestions 
continued to flow in demonstrating it had a wide variety of users. 
However it was also free, which made it difficult to justify 
dedicating engineering resources to improving it. Unwilling, or 
unable, to see that HyperCard was making the Macintosh platform, as a 
whole, much more interesting to the market, management let it 
languish.

If you update DreamCard now, you will get engine updates for the length of
that update period. A lot of what makes Revolution what it is, is in the
engine.

Re: Locking Messages

[Rob Cozens]

Hi Bridger,


I have a stack (Which I will call Stack 1) that
makes another stack (I will call it Stack 2), copies a card from some
other stack running in the background (which I call Stack 3) and sends
the new stack with the copied card all over the network where it is
added to whatever stack sees it.  The problem is that sometimes the
card on Stack 2 has unexpected handler in it that cause random errors
when I am working with it.  I realize I can lock the messages, but
that locks the messages for the Stack 1 also, which I cannot do.  Is
there any way of keeping messages from being passed to Stack 2,
without locking the messages from Stack 1?



I am not sure exactly what you are describing.

If Stack 2 is created on-the-fly, where does the "unexpected" handler 
come from?  The card copied from Stack 3?


Do you have handlers with identical names in Stack 1 and 2?

If Stacks 1, 2, & 3 are all your creations, you should be able to avoid 
any duplication.


If the error is caused by broadcasting a message (eg: doWhatever), 
perhaps the problem can be avoided by directing the message to the 
correct object (eg: send "doWhatever" to card 1 of stack "Stack 1").

Re: Scrollbar to drag through a movie?

Hi Jim,

Is is possible to drag smoothly through the video frames of a movie  
using  a scrollbar?


with version 2.6.1 this is only possible when the QT controller is  
visible

OR
(if the controller is not visible) when the movie is already  
playing...?!


This was possible with earlier versions of Rev :-/

But with Rev 2.7 this is possible again :-)

Just set the startvalue of your slider to 0 and the endvalue to the  
duration of the player...


on scrollbardrag tValue
  set the currenttime of player xyz to tValue
end scrollbardrag

C'est ca :-)

I can drag to a current time and then start from that point, but I  
would like to see the frames shuttle by as I drag the thumb.


Hope that helps...

sorry, but I do not have an answer, but I, personally, consider this

If the chunk contains more than one font, the chunk's textFont

But even if the textfont is identical and only the styles are "mixed"  
I get

put the textfont of line 1 of fld 1 -> "mixed

Re: Locking Messages

[Bridger Maxwell]

Hey,
  Sorry I wasn't very clear on my question.  I have made a stack (Stack 1)
that copies a card from any stack running in the background (Stack 3),
pastes it on another stack that was just made (Stack 2), and sends stack 2
over the network where the card that was added to any stack that intercepts
it.  It is made to be able to add any card to any stack.  The thing is a
card may have a handler in it that is triggered, that refers to an object on
another card.  Because it has been seperated from the rest of the stack, it
can't find that object and it causes errors.  Once it is inserted into the
new stack it should stop causing errors, but until then I need to lock the
messages to the stack holding the card so it doesn't trigger anything.  I
can't really predict what handlers will be triggered, or what the errors are
going to be so I can't just intercept them beforehand.  Any ideas?

No Openstack ..... !

[Francis Nugent Dixon]

Hi from Paris,

I have just run into my first Platform problem, but in fact,
my problem started on my Mac, and hasn't gone away !.
I finished developing a stack on my Mac. During development,
I couldn't get it to run the OpenStack script (why I don't know).
I found that when using Stack Runner, OpenStack WAS executed,
so while I was testing on the Mac, each time I loaded, I executed
the openStack command from the message box, and execution
was fine (dirty but fine !). I imagined that DreamCard Player on
the PC would work the same way as Stack Runner on the Mac.

Unfortunately, when I execute the stack on my PC using the
DreamCard player, OpenStack is NOT executed, and so my
stack serves no purpose, because I initialize global variables
which are essential for execution.

So, back to the Mac to create a button to execute openStack,
then back to the PC. When I click on the button on the PC,
nothing happens, so I am back to square one. What is going
wrong, or more specifically, what am I doing wrong ?

-Francis

It sounds like a platform-related script error that is causing the 
handler to abort. Can you post your openstack handler here?

Jeff,

Actually, we saw this happen when doing an osx <> XP transfer.

The one was the 'regular' file that we couldn't open, the other was

Neither was functional :-(

Thanks, though!

So use StackRunner (which beats the pants off the Dreamcard player

Re: The End of Dreamcard? -- but life after death?

[jeffrey reynolds]

Man i am feeling old... I created Apples first educational CD-ROM  
(Earth Explorer - a multimedia environmental encyclopedia for jr high  
kids) when they decided to get into the CD-ROM business in the early  
90s using hypercard. they were amazed that a sophisticated multimedia  
product could be developed with hypercard. i had a meeting with  
higher ups at Apple to assure them that it was possible... their  
testing dept. finally confirmed that it worked and was relatively bug  
free! It struck me funny i had to sell the idea to Apple. in contrast  
the PC version (done in VB) took about 4x the person-hours to  
complete the software and that was with the content being squeaky  
clean (the mac version was 6 months ahead and did all the content  
testing) and content being exported to them exactly how they wanted  
it (i got it in all sorts of various forms that i used HC to convert  
to the final formats i needed--one of HC, strongest points). They had  
about 8 fat bug binders, i had about 2 and that included all the  
content bugs! The other guys were pro programmers with degrees and  
much better programmers than me (i was a molecular biologist and self  
taught programmer).


when i was designing the product i had mocked it up in hc and the  
company developing it was planning on programming it in C, but then  
when the mock up was doing 90% of what needed to be done I proposed  
me just doing it in HC. Boy did that get a laugh from the programming  
dept at first. but then they shut up when they realized that yes the  
prototype did just about everything that it needed to be done just  
fine (what was left was minor stuff that we took care of with a  
couple of custom externals) and the budget and timeline was a  
fraction of doing it all in C.


oh and it will still run today, even under classic. funny thing is  
cdroms are now getting very popular back in schools (they are finding  
the internet is not the solution to all educational content delivery  
-- realities of working in a school) and the product may be dusted  
off, content updated and new software done with revolution!


Just shows you what was possible with that quirky little piece of  
software. I dont think Apple fully realized how much HC was a part of  
the success of Apple in general. Apple survived on the fringes by the  
undying passion of users that things like HC kept going. Without them  
they would have never gotten a big enough market share to hold on or  
enough reasons why their hardware was at a premium price w/o the  
evangelists selling it so hard and passionately.


I think the lesson here is that there are options to make great stuff  
out of older things like stuff created in dreamcard. yes the simple,  
cheap gui building system like HC wont be there, but the work done in  
it can be moved forward and useful. No system lasts for ever, but  
moving stuff forward is possible and can really pull some rabbits out  
of the hat...


cheers,

jeff reynolds

Hi Jacqueline,

You wanted my "openStack" script, so here it is.
But I can't see anything in there that can cause

It works perfectly well when I type "OpenStack" in the
message box (on my Mac).

Thanks for looking.

Good guess, but Director/Videoworks didn't add a scripting language

No, and if there was a Bill A. from PARC who premiered a product at

Re: The End of Dreamcard?

[Dan Shafer]

I have no inside info on this, so I'm more or less guessing but here's my
take.

Dreamcard was a "crippled Rev." It straddled the lines of an inventive user
and a professional developer but the lines were blurred and the audiences
and messages so different that it created as much confusion as it did
anything else.

So RR decided to replace DC with two paths. If you want the power of Rev,
buy Rev. (My guess -- and I reiterate my caveat -- is that they'll make this
upgrade very attractive from a price standpoint because they have nothing to
gain by driving away DC users who are basically happy). The alternate path
is you want to use a Rev product that's more like the old HC and somewhat
like multimedia authoring tools, so you buy Media at a much lower price
point but you limit yourself to certain types of apps.

I think the company has created a bit of a difficult-to-decode message on
the main rev media page because of this statement: "*Revolution
Media's*simplicity makes it ideal for creating software utilities
quickly and
easily. You can conceptualize a project or solution, but what is the
fastest, most productive way to turn your ideas into software? Its *Revolution
Media*." That makes it sound like Media will include the full Transcript
language, which then begs the question of the real differences between the
products. Then on the detail  page there's this somewhat confusing tidbit:

"Use Revolution, the English like, built-in language, to add the *step by
step logic *of your concept to your creation." I suspect -- but again my
caveat -- that this is just a mistake, that the language is called
Transcript, not Revolution (which would be devilishly confusing, no?).

In the end, the important thing I think is that DC users now have to decide
whether they are fish or fowl and head down the path that suits them best.
Probably not a bad move for the company; Media sounds like a truly
consumer-appealing product.

Well, I didn't feel confused at all. Dreamcard is, or was, "crippled"  
only in two ways: no standalones, no Oracle-type dbs. Not significant  
drawbacks for someone building open-source academic tutorial apps.  
And while the (if I recall correctly) $60 academic price, for someone  
with no institutional or corporate budget to call upon, wasn't  
nothing -- wasn't, in other words, as attractive as the price of  
something like Python + wxPython. which I use to build other academic  
tutorial apps; as as Hypercard for that matter -- it was worth it, if  
what you wanted to do was specifically Hypercard-like. I had an old  
Hypercard tutorial I wanted to modernize, and doing it in Python  
would have been perhaps more work than it was worth.


As for attractive upgrade prices for Studio, the best I have seen so  
far is $200. It does not attract me.


Whether it's a wise business move on Rev's part I suppose I can't  
judge, and I really don't care. Unless I've misunderstood something  
in the deal, or in Media -- and I certainly agree that the p.r. has  
been confusing -- I'll be waving bye-bye to Rev toot sweet. (Or keep  
using the old one? I don't think so, except for the occasional jiffy  
stack. Or pay $50 for a final year of upgrades to the engine? High  
price for a dead-end street.)


Get out your handkerchiefs? Of course not. The question, for Rev, is  
whether users like me are as trivial a proportion, and as trivial a  
segment, of their market as they *appear* to think. I'm holding my  
fire until I understand better. But that's the way it looks so far.

Re: The End of Dreamcard?

[Dennis Brown]

I was not impressed with the new plan either.  I own Studio, but  
bought DC when they first offered it because it was an economical way  
to stay up to date.  I had no interest in compiling my apps.  Most of  
the nifty upgrades to the language are eye candy that real app  
developers might appreciate, but my personal needs are more simple,  
but I really appreciate the bug fixes.  I bought the first SuperCard  
cross grade offering of Revolution when it first came out, and have  
only used it a lot in the last year.   I just wanted a good XTalk  
interpreter environment to make my own inventive tools, but I need  
speed to crunch a lot of numbers and Rev was faster than my  
SuperCard.  I found DC to exactly match my needs as a personal  
programming tool --no confusion at all.


I appreciated the one year extension offer (which I purchased),  
because it gives me another year of upgrades, at a price I was  
expecting to pay each year, in which to evaluate my changing needs  
and to evaluate if Media is sufficient for me.  I am sure it would  
work fine for me.  However, I am not so sure about this backdrop  
stuff.  I don't have any programs that take over my screen on my  
desktop.  I keep a lot of programs open at the same time on two  
monitors.  If it blanks them out, I will most likely keep using DC  
until it won't run on my machine anymore, then decide if I want to  
update Studio or go back to SuperCard, or something else.  However,  
by that time Rev may have a whole new plan and product slate.


My point is this, the good Rev folks gave me a reasonable option to  
continue the way I was and decide later.  I don't feel like I have  
been trapped in a corner, and have to decide what to do now.  I have  
time on my side.


I do hope Media is successful in making Rev more accessible to a  
larger audience.  I will give it a test run after it comes out.  My  
personal opinion though is that having a programming UI like  
Constellation makes it much easier to use Transcript.  The Rev folks  
might want to rethink that end of things for their entry level app.

Well, I didn't feel confused at all. Dreamcard is, or was,  
"crippled" only in two ways: no standalones, no Oracle-type dbs.  
Not significant drawbacks for someone building open-source academic  
tutorial apps. And while the (if I recall correctly) $60 academic  
price, for someone with no institutional or corporate budget to  
call upon, wasn't nothing -- wasn't, in other words, as attractive  
as the price of something like Python + wxPython. which I use to  
build other academic tutorial apps; as as Hypercard for that matter  
-- it was worth it, if what you wanted to do was specifically  
Hypercard-like. I had an old Hypercard tutorial I wanted to  
modernize, and doing it in Python would have been perhaps more work  
than it was worth.


As for attractive upgrade prices for Studio, the best I have seen  
so far is $200. It does not attract me.


Whether it's a wise business move on Rev's part I suppose I can't  
judge, and I really don't care. Unless I've misunderstood something  
in the deal, or in Media -- and I certainly agree that the p.r. has  
been confusing -- I'll be waving bye-bye to Rev toot sweet. (Or  
keep using the old one? I don't think so, except for the occasional  
jiffy stack. Or pay $50 for a final year of upgrades to the engine?  
High price for a dead-end street.)


Get out your handkerchiefs? Of course not. The question, for Rev,  
is whether users like me are as trivial a proportion, and as  
trivial a segment, of their market as they *appear* to think. I'm  
holding my fire until I understand better. But that's the way it  
looks so far.

Hi Jacqueline,

You wanted my "openStack" script, so here it is.
But I can't see anything in there that can cause

It works perfectly well when I type "OpenStack" in the
message box (on my Mac).


I'm not sure why it works on Mac either, actually, but maybe I am 
misinterpreting the script. You have many variables that are not defined:


myImpExpFileName
myDataFolderName
myPrintFileName

etc. Do you have fields that are named those things? If so, put them in 
quotation marks, like this:


if exists(field "MyImpExpFileName") then...

If you do not have fields named MyImpExpFileName, etc. then those lines 
of script will never execute. But you say they work on Mac, so maybe you 
do have fields named that way.


This looks wrong to me too:

  put "\Revolution\" into GVStackPath...

Paths in Revolution always use forward slashes, so it should be:

  put "/Revolution/" into GVStackPath

same as on Macs. This might be why the script does not work on Windows.

For a test, try making a simple stack with a simple openStack script. 
Maybe like this:


 on openstack
   put "Openstack sent"
 end openstack

Then run the stack on Windows. You should see "openstack sent" displayed 
in the message box. That means the message was sent properly.


Finally, try putting a breakpoint next to one of the lines in your 
openstack handler. When you open the stack on Windows, you should drop 
into the debugger when it finds that breakpoint. Then you can step 
through each line to see what is going wrong.


If you do not drop into the debugger, then you are right, the openstack 
message is probably not being sent to your stack. That usually means 
another script has blocked it somewhere, maybe in a frontscript.

Windows file visibility

[Marty Knapp]

I've been playing with a recipe from the Scripter's Scrapbook 
(setFileVisibility) but I can't seem to make it work on my XP machine. I 
poked around on Google but didn't find anything that really helped.


basically I'm doing this:
#creating a text file
#then attempt to make it invisible:

put "attrib +h" && thePathToMyFile into commandString
get shell commandString

But my file remains visible. Perhaps this works on older versions of 
Windows? My Windows skills are pretty basic, so I may be missing 
something simple.


Thanks for any help,
Marty Knapp

Marty,

You may just be conflicting with your OS settings. Do you have XP folder 
options set to show hidden files? Another possibility is that you are 
using a / rather than a \ as the path folder delimiter. Any time you use 
shell on Windows, you need to replace "/" with "\" in commandString before 
executing the get shell command.

Hey Roger,

I tried the delimiter both ways and checked (and reset) my folder

"Hidden" is not checked after I've run the shell command on it . . .

Perhaps Run Rev are trying to confuse us all - you can read these two
quotes from the same page at http://revstudio.runrev.com/easy.php  :

'Then use Transcript, Revolution's built-in scripting language, to add

Are there any spaces in thePathToMyFile? If so, try enclosing it in

Way to do RegEx substring replacements?

[Jim Witte]

Is there a way in Revolution (2.0.3) to do a RegEx find and replace  
using one of the sub-expressions, like finding


() ([^x]*)x.*

and replacing by

\1\t\2

directly without having to use matchText to extract the  
subexpressions and then construct the line? (Yes, I know this should  
be in Perl, Python, or something else - that's next after the  
prototype is done)

Re: The End of Dreamcard?

Ah, those were heady days... I was at that Boston MacWorld (visiting 
on my first trip from Australia). Someone recommended that I go check 
out this new "HyperCard" and I saw Bill Atkinson presenting it. I ended 
up scoring an "ACME Bowling" team jacket (which was the HyperCard 
developer team official apparel. Ended up working at Apple, developing 
HyperCard toolkits, templates etc...


Ya gotta love that I was able to open some of my developer tool stacks 
from that time in Rev and it still all worked.

Many HC fans know that HyperCard was originally designed without a

Which multimedia authoring tool had a scripting language and premiered
at the Boston expo the year before HC was released?

See if the "replaceText" function does what you want.

Stripping trailing spaces from a string

get matchText(theExpr, "(.*)\s*", theExpr)

where theExpr is "0025E95C mov  r5, r0 "

--For the price -- roughly half of what Hypercard last sold for --  it
seems fair enough.  Can you do mySQL and CGIs in PowerPoint? (not being
nasty: I really don't know but doubt it as I don't think it has a

As for templates, I, for one, am doing the Snoopy dance.  Hypercard had

Not that I know of, but I am curious why this is needed.

Be careful that you only have one possible match and that you consider
'greedy' and case sensitive when applying RegEx since \1  and \2 may not be
what you expect.

If given that there is only one possible way to get a match then it is not
really a problem to use two lines to produce the result:

put matchText(lineOfText, "(?Ui)(...)([^x]*)x.*",v1,v2) into vTrueFalse
if vTrueFalse = "true" then
   put v1 & tab & v2 into outputStr
else
   answer "Match not successful, take alternate actions"
end if

Why is this an issue for you?
Do you mean that you want to do more than one replacement in a single text
block?  In that case, I use matchChunk & a repeat loop & temp variables.

>(Yes, I know this should
> be in Perl, Python, or something else - that's next after the

Not sure what you mean by this.  I use RegEx quite often in Rev routines, as
well as filter, replace, replaceText.

Here's a version I have that trims whitespace from both sides of a string,
and includes 'normal' whitespace, along with hard spaces (watch word wraps):

function trim pWhat
  local dummy,tRetVal
  if the platform is "MacOS" then put "\xca" into tHardSpc
  else put "\xa0" into tHardSpc
  get matchText(pWhat, "(?s)^(\s|" & tHardSpc & ")*(.*?)(\s|" & tHardSpc &
")*$",dummy,tRetVal)
  return tRetVal
end trim

However using RegEx for trimming is not the fastest approach, although the
difference between 0.0391 ticks for the RegEx version vs. 0.0004 ticks for
the fastest version is not recognizable unless you have to do it thousands
of times...

   put "(.*[^\s])" into regEx --trims spaces from right
  get matchText(strr,regEx,strr)

Basically says capture the whole string and come back until the character is
not a "word delimiter", not necessarily a space.  If you only want spaces to
qualify then use

put "(.*[^\ ])" into regEx --trims spaces from right
(note the space char after the "\")


put "([^\s]+)" into RegEx  --matches only the first word

Basically says capture the characters as long as it is not a "word
delimiter".


Ken has MUCH better experience and even gives time trial results :-)
