I continue to use F-Script occasionally to investigate how programs work internally. The framework itself has been updated to handle the changes in OS X Mavericks. However, the developer tools included with Xcode 5 swap out the gdb debugger for lldb, breaking the injection script again. After playing around with the automator action some more, here's what I came up with that works on Mavericks.
I wanted to use the very handy F-Script environment to snoop around inside an application. F-Script can be injected into running applications by using gdb, which of course works fine, but they also provide a services-menu item for performing the injection. Due to several changes in OS X 10.7 Lion, the automator workflow that came with F-Script to perform this did not work.
I reworked the injector service so it works on Lion and doesn't leave behind (or even create) any temp files.
