How do I run a system command in a cydget using objective c or javascript?

Question

Hi!

I am trying to run a Ruby script from a cydget (cydget is a framework made by Saurik for writing lockscreens on the iPhone, using cycript, which is a mix of javascript & objc - see http://www.cycript.org/ ) The script will first check to see if a WEBrick server is running, if so it will quietly exit, if not it will start the server. Apparently the iPhone doesn't support NSTask, and I don't know if the cycript implementation of obj-c does or not. (To be honest, I have no clue how obj-c in cycript works at all!) I'm not worried about security, because I'm running 1 specific command: "ruby server.rb", and everything else will be handled through the web server itself.

Is there any way other than NSTask in objective-c, or any way in javascript or HTML that I can run an arbitrary command on the local machine?

Thank you!

Answer 1

You can't fork another process on an iPhone at all (assuming we're talking about a legitimate app developed against Apple's official SDK). No NSTask, no fork()/exec(), no system(), nothing.

So it sounds like the best solution is to just wait - Saurik will be coming out with a way of directly using Ruby in a cydget, but it likely won't be out for a few months... :( I hope it will be worth the wait though!
