OpenXSpell aims to bring comprehensive and flexible open source spell checking to the Mac OS X platform. The project was born of a frustration with the limitations of the native AppleSpell spell checking service which provides support for only a very limited number of languages. OpenXSpell makes use of the excellent Enchant library, which makes it possible to use a number of different spell checking back-ends, including Aspell, ISpell, MySpell, and Hunspell.
iHook is a graphical frontend for any command-line executable. It gives scripts a pleasant Aqua face, and allows script writers to provide graphical feedback without having to learn one of the higher APIs available for Mac OS X. iHook accomplishes this through its ability to understand a set of directives. When a script writes an iHook Directive to stdout, iHook will modify its own interface based on the content of the Directive. In this way, a simple shell script can have an Aqua interface, complete with a progress bar and drawer. When launched in the Finder, iHook prompts the user to choose a script to run; iHook also accepts file drops on its icon, and will attempt to run the dropped file. When no user is logged in, iHook tries to execute /etc/logout.hook. This makes iHook highly useful as an interface for Mac OS X LogoutHooks.
