I've built a fair number of multimedia CBTs in Rev/MC, as has Sun
Microsystems and others.

If the features you need have been requested by enough people, I'd be
surprised if they weren't prioritized appropriately.

CSS is a browser specification.  I haven't worked in Director for years, but
I don't recall that market-leading multimedia tool supporting CSS, or many
other browser specifications either.

I'm not sure how Director engine compensates for the OS differences in font
metrics, but Rev offers the Profile Manager which lets you apply OS-specific
settings for objects.

Just how big?  I've released a number of OS X apps and have not had that
reported here.

Given my experience with the folks at RunRev and MetaCard, I'm confident
that any reproducible bug of that nature will be addressed in the next
release.  

All software always has bugs. 100% of serious bugs I've reported in the Rev
engine have been fixed or are actively in progress toward a fix.  And giving
credit where due, I've never seen anyone match the turnaround time for bug
fixes with the consistent speed of Scott Raney (MetaCard Corp.), and Tuviah
Snyder (whose done wonders with some of the multimedia support -- QT and
otherwise -- in the engine).

I can find few tools which export RTF that don't also export HTML.  For me
it does what I need and lets me move on to other things.

I understand from your series of posts on the matter that RTF is important
to you.  If enough other people need it I'm sure the Rev team will
prioritize it appropriately.  I've never seen them turn down a thousand
sales because they simply didn't feel like adding a particular feature. :)

Why doesn't someone craft a Transcript lib for importing RTF?  Geoff -- got
some time on your hands? :)

If I'm not mistaken RTF is a proprietary Microsoft format.  They do not
require licensing fees, but they do control the specification.

For this reason the modern open standard for internationalization is Unicode
(see <http://www.w3.org/International/>), as implemented in the open
standard for SGML and its offspring HTML.

Rev currently has a very modest level of support for Unicode, and it's my
understanding that a more complete implementation which will handle
double-byte characters is in the works.

...if you paste that in a Rev field and get the htmlText, you get:

  <p>Ä Ü Ö ß, ë ì î ñ
  ó ò û Æ ÿ Â Á</p>

Which of those is not translated correctly?

You got a word processor that handles <backgroundcolor>?  :)

But seriously, the only significant difference I've found is that browsers
are designed to render text in relative sizes, while Rev/MC does what you're
asking for:  it works in fixed pixel sizes.

MetaCard predates CSS, so when it was time to implement an ASCII format for
describing text attributes within the engine they chose a solution that
works well within the engine: fonts are specified by pixel size.

If you need to export styled text for other applications you'll need to come
up with a solution for the target app.  For example, if you're exporting to
a relative-text-size app like a browser, you can do a replace on the font
strings to render them however you like.  If you want pixel-specific text
sizes that will work across all browsers (IE seems to handle MC HTML fine as
it is) you can generate CSS definitions for your output header.  And since
CSS supports a corollary to backgroundcolor you can have that too.  :)

If it turns out that a lot of users need to export for browsers, let's
continue this on the xtalk list where discussion of the details of such
language additions are handled.

My post was weak in its distinction.  Yes, an "application" is an executable
file, so any EXE would apply.  The distinction I was after was "multimedia
application" (like the excellent Rosetta Stone series) as opposed to what we
might call "production application", the traditional world of things like
word processors, spreadsheets, CAD, and other categories which we could
characterize as producing a tangible user-created output.

In this sense, "production applications" can be seen as specialized
authoring tools:  with a word processor you author a novel, with a
spreadsheet you author a business model, with CAD you author maps, etc.  I
think it's this sort of thinking behind Appleton's comment about "a tool
that creates authoring systems".

Of course it would be silly to author a full-fledged word processor in Rev,
with so many great ones out there.  A "production application" development
tool like Rev is best applied for vertical market solutions for which C++
would be cost-prohibitive, or at best less cost-advantageous.

There are an uncountable number of software categories that are well-suited
for something like Rev, with a million more waiting to be discovered.

You might be able to make a mapping program using Director, but Director was
never designed as a general "production application" development
environment, so I suspect it'd be more work than using something built for
the job like Rev.

Nothing, but if you need to hire programmers for Director and not for Rev
that makes a powerful statement about the accessibility of each product.

Submit a reproducible recipe with your bug report and work on other aspects
of your program while they resolve it.

If you have needs that are better addressed by another tool, only you can
make that determination based on the unique requirements of the project at
hand.

Are these script errors or hard crashes?  If the latter, submit a recipe for
reproducing the error and the Rev team can address it for you.  If it's in
the scripts it takes more work. :)

A monochrome single-window architecture with a limited object model that

Ten times the development cycle, half the runtime speed.  Or as a friend

Yes, HC requires a lot of HC-specific externals.
When OS X no longer boots into Classic will they have time?
...

And the standard for operating systems is Microsoft Windows.  ;)

The standard for diagramming is Visio.  Does that mean no other
diagramming/CAD/concept mapping tool can have any value, no matter how well
it addresses a specific need?

No single tool does everything in every category better than all others.

While the size of an installed user base plays a useful role in making
choices,  the smart developer also does a critical analysis of the
requirements of the project at hand vs. the features available in each tool.

> A assume that not all german speaking developer are idiots

Germans are some of the best gadgeteers in history.  GoLive was and largely
still is developed by a team of Germans, and IMHO it's a work of genius.
And of course there are the classic Mercedes....

Spread the word, brother.  Helping humanity save millions of hours with true
rapid development....

(wow, have I been having too much fun with this tool or what?)
