One of Rev's great characteristics is its portability. A Rev standalone
doesn't need a setup. If you create an app in Windows, you can easily
load up the same project in Macintosh, create a new standalone, and
provided no adjustments to the handling of the file system are needed,
the app will run just as well on Mac as it does on Windows. Great!
But, to use a phrase I know Dan loves, there is a fly in the ointment.
The Windows file system is different to the Macintosh file system is
different to the Linux file system is different to the ..... So if your
app makes heavy use of the file system, to run it anywhere, you either
have to make it detect and adjust to the specific operating system it is
running on, or you have to produce different versions of the app for use
on different operating systems. Damn!
Please correct me if I am wrong. One very easy way around this problem
is to use Linux. And only Linux. You don't need to install Linux on your
HD, or Rev/Linux for that matter. Get yourself a pendrive. If you want
to, you can get one with Linux (e.g. Mandriva) already installed on it.
Personally, I prefer to install my own version of Puppy Linux on the
pendrive. It is so easy that even I can do it very quickly with no
hassle at all. Just follow the simple instructions at the Puppy site. So
now you can carry the operating system, Rev/Linux and your apps around
in your pocket. And you really do only have to create a single version
of your app. By this method, Rev is not "cross-platform", it is the
operating system itself which is "cross-computer"!
Strangely, a great number of quite modern computers cannot be booted
directly from the USB device. In practice, though, this problem is very
small. In Puppy, it takes about 1 minute to produce a fat16 diskette for
Windows. Use this to boot your pendrive. In other pre-prepared systems
(e.g. Mandriva) you can create a CD to do the boot (possibly for
Macintosh too, I can't quite remember).
