I suggest that he use the one thing about an app that a user
can modify, that is, its Finder comments. Luckily Spotlight in Mac
OS X 10.4 gives us a very convenient API to get the value of
whatever the user has set by choosing the app in the Finder, doing a
Get Info, and typing a string into Comments.
thats an interesting solution, but i would be using Comments which
aren't Comments, they're Args. i think the CFblahArg key hack is
cleaner.
So let's just make this the extra args field for his purposes.
Change main to appMain (to move it aside) and write a new main like this:
uh oh, you just broke something: i have to have a special main for OSX.
This extracts the Finder comments, parses them into an arg list, and
calls your old main with the argc and argv it expects. It's
#ifdefed so that when compiled on a non-Mac platform it's basically
a one-stack-frame pass-through.
i really appreciate this solution and the time you spent coding a
case for it, but i honestly think that i'd be going down the wrong
path to bork the Comments namespace, when i could isolate the args
into the Info.plist key namespaces, and not end up altering the
purpose of other aspects of the Finder interface..
Code tested and works, but cleanup and error-checking are left as an
exercise for the reader. Note that this does not do all the quoting
and globbing that a shell would; you can go to town with that if you
want. It considers every space a delimiter; you can do more
sophisticated scanning on the string if you choose
(CFStringCreateArrayBySeparatingStrings looked convenient).
Mac OS X 10.4 only.
heh heh. thanks for the idea; i've chosen the CFblahArgs key as a
home for my argv, and i'm moving on ..
