I'd like to be able to write a .swf file that is runnable as a command line app. In other words, I would be able to create actionscript classes which can interact with stdin and stdout, and could then execute that .swf directly in the command line.
I suspect that this isn't really possible. Can anyone confirm that?
EDIT: A couple of the answers pointed out that using Flash for command line work probably isn't the best choice. I wholeheartedly agree in most situations. The reason I am asking about this is because I want to do some AS3 code generation, and reflecting on AS3 classes within the runtime would be easier than parsing the code or walking the intermediary XML that asdoc produces. I'm doing the XML approach now in Ruby, but would love to have a cleaner solution!
Nope--not possible. The best you can do is a standalone app (which can be made in Flash or with a Projector version of flash player, available from the Adobe website).
And why would you want to--Flash is awesome because of the great GUI capabilities. There are plenty of other programming languages that are much better suited for the command line (Python or Ruby or, god forbid, even Perl)
