With your shell script and garbling characters, I think a combination
of quoting the path and writing a handler to replace these characters
with the escaped form would be part of the way to solving your
problem. Add that to the alias method and you're probably some way
there.

I've been using various means to get the resource path of my app

the last few years, the most useful being "resource path of main

Other ways include variations on "path to me". These all seem to

the path of the app when it is first launched, which theoretically
should be
fine. Unfortunately, I have found that a small number of users like
to move
apps while they're running, which invalidates the resource path
determined
at launch time. And then many of the "do shell script" calls in my
apps go
haywire as the files they're referring to are not in the right place.
Does anyone have an idiot-proof way to determine the app bundle path
in real
time that would be practical for on-the-fly location of resources to
be used
in do shell script calls? Right now, I found I can sort of handle the
situation by doing a "path to me" call within a try block at top level
handlers in my script, and when it fails, I put up a dialog telling
the user
the app was moved and needs to be quit now. But if there's an
efficient way
to avoid the situation altogether, that would be even better.
I've also been running into users who skip the advice to install my
apps
directly in /Applications and stick them in folders with names like
"~~
Bill's <freakin> Wonderful! $oftware Folder ~~", which wreaks havoc
with do
shell script when it tries to refer to resources in the app bundle,
but I
think that is best handled with a warning at launch time, since I
can detect
it right away. But if anyone has ideas on that, I'd like to hear
them as
well. Generally, the judicious application of quotes (or quoted
form of)
can handle most meta-character that have special meaning in the UNIX
shell,
but there are some oddball situations.
Thanks,
Craig
