The coolest thing somebody did with WebStar was to integrate it with HyperCard so you could actually publish live INTERACTIVE HyperCard stacks on the web, that you could see as images you could click on to follow links, and followed by html form elements corresponding to the text fields, radio buttons, checkboxes, drop down menus, scrolling lists, etc in the HyperCard stack that you could use in the browser to interactive with live HyperCard pages!
That was the earliest easiest way that non-programmers and even kids could both not just create graphical web pages, but publish live interactive apps on the web!
The following is taken from the LiveCard web site
(http://www.royalsoftware.com):
"LiveCard is a HyperCard add-on that enables remote users to browse
and interact with HyperCard files, called "stacks", on your web
server. Once installed, you'll be able to serve any HyperCard stack
without extensive preparation - often with no preparation at all.
This means you have all the advantages of HyperCard as part of your
server solution, plus you can now serve those stacks to anyone on
the Web, regardless of whether they're using a text- or
graphics-based browser and regardless of their platform: Macintosh,
Windows, UNIX, whatever."
"LiveCard implements a CGI (Common Gateway Interface) between
Macintosh servers, such as WebStar, and HyperCard. It makes the
HyperCard interface available as high-resolution, compressed
image-maps and HTML form elements, and transforms user gestures in a
web browser to a format HyperCard can understand. LiveCard
translates between HTML, HTTP, and HyperCard "on the fly," requiring
little or no preparation of the HyperCard stack. LiveCard generates
HTML dynamically - as stack content and functionality changes, these
changes are reflected live in the remote users browser."
What does this mean for you? Well, if you have access to a Macintosh
web server running WebStar, MacHTTP, or similar server software that
is cgi-aware, you can serve your stacks using LiveCard. LiveCard can
generate an HTML forms page using the text fields on the card, an
image map with stack graphics and buttons that responds to user
clicks (although the buttons can't highlight), or a combination of
the two. In addition, each generated page has a header and footer
that can be set by scripting...and is HTML aware. This gives an
incredible amount of flexibility.
Note that LiveCard requires a Macintosh web server (not really a
criticism... I love Mac servers...but you do have to have access to
the server, and it *has* to be a Mac, since LiveCard is
HyperCard-based). And to fully realize the potential of LiveCard,
you need to learn some new commands...but there aren't too many, and
they make sense. Plus, the examples provided are very helpful. At
this point in time LiveCard has a limited ability to work with
QuickTime...you can kludge your way around the limitations, but if
your stack relies on a lot of QuickTime, you have to do some serious
modifications. Rumor has it that future versions will have more
QuickTime functionality. But for static graphics (color spoken
here!), there are no modifications.
Where LiveCard really shines is in the area of forms and databases.
I created a stack to be used for a course I was teaching...very
simple, with about 5 text fields for the students name, college,
major, and a topic they were interested in. I then just dragged this
stack into my server folder where LiveCard resides. That was it. I
called up my page on a browser (remember, any browser, any
platform), went to the LiveCard page, clicked on the link to my
stack (automatically created by LiveCard), and there was a
forms-based page with all of the fields...including their labels. I
filled the page out and hit submit. Voila...the data appeared on the
stack residing on my server. Now that is cool.
Pros: Can serve your stack mostly without modification. Can use
externals in the stack. Browser is *completely* platform independent
since a plug-in is not required. Data can be easily transferred
between web page and stack. Leverages existing HyperCard stacks,
especially databases and order processing.
Cons: Requires a Macintosh web server. Limited ability to work with
QuickTime. Can be a tad slow. Lose button highlights and card
transitions.
3. Convert your stack to a SuperCard project. Allegiant (makers of
SuperCard - http://www.allegiant.com) has recently released
Roadster, which is a plug-in for Netscape navigator. Roadster is in
public beta at this time (December '96), and is available for both
Mac *AND* Windows 95. Can anyone say cross-platform? Before you get
too excited, remember that you first have to convert your HyperCard
stack into a SuperCard project. This is fairly painless
however...unless you use externals. Externals present two problems
for the SuperCard/Roadster approach...they don't always convert, and
more importantly, at this time Roadster does not support *any*
XCMD's. This is due to security concerns (you could do some nasty
damage to a client computer...kinda like a java applet gone bad). A
future intranet version of Roadster may show up that supports
externals. Another potential problem is that Roadster only supports
a single window. Now this might not be a problem for HyperCarders,
since one window is the norm. But for dedicated SuperCard people
that have grown used to multiple windows in projects, some tinkering
has to be done.
Since Roadster is a plug-in, you get some more good news and bad
news. The bad news is that people have to download the plug-in and
install it into their Netscape Plug-ins folder before they can view
your project. The good news is the plug-in is free, and your project
runs in the browser exactly as it does on the desktop...buttons
highlight, transitions work, etc... And perhaps even more
importantly, Roadster is available for Windows, so you can finally
get your stack into the hands of the unfortunate Intel-laden masses.
Pros: Project looks and runs just like on the desktop.
Cross-platform. Ability to transfer information via forms commands.
Ability to cache and preload graphics. Very good with external media
such as QuickTime, audio, etc.
Cons: Have to convert your stack. Browser requires plug-in. Lose all
functionality of externals.
