Since you come from a SuperCard background could
you answer a question for me?
I am a registered owner of SuperCard 4.6 and SuperEdit 4.6.
The Xtend section allows you to export externals. I contacted
SuperCard Support and they said I could use the SuperCard
externals in other programs that use externals as long as I
abide by the EULA. That is not a problem.
I exported a external and tried to use it in Revolution and could
not get it to work. The next thing I was going to try is to make a
empty external for LiveCode naming it the same as the external
I want to use and from SuperCard install it into the resource by
changing the type from .bundle to .txt and then change the type
back to .bundle. I have done that without making the empty
external so I have not actually tried it yet. Is that the proper
way to install a SuperCard external in Rev or is it not possible
at all to use them in Rev?
I'm very familiar with SC externals indeed: I started Fourth World in
1994 primarily as a vendor of SuperCard add-ons, with a catalog of
externals written by myself and many others, including one of the
current co-owners of SC, Mark Lucas.
Even back in those days, not all externals could be used across the
various apps that supported the HyperCard externals interface. The
SuperCard Internals Toolbox, for example, included many APIs not found
in HyperCard, so many of the best SC externals couldn't run in HC (or
OMO, or Microphone, or any of the other apps that supported the original
HC externals interface).
The migration from 68x to PPC compounded the compatibility issue, as has
the move from PPC to Intel. Today, even SC itself can only run a subset
of all the externals ever written for it; I don't think anything I'd
ever published can be run with SC today.
With LC, the externals API is very different, so even if you had an
Intel-compatible external and only needed to run it on Mac, it would
still need to be recompiled to use the LiveCode externals APIs.
Fortunately, at least for the work I do, aside from the database
externals included with LC I rarely use any at all. Most of the things
I'd written externals for in SC are included in LiveCode itself.
Which externals from Xtend do you need?
I'll bet there are LiveCode equivalents for most of them, or easily
written using LiveCode itself.
