Hi,

I'd like to know if I may use your script for inclusion in the Grails package for Ubuntu. The package is almost ready to go out, and then I came across your script. It might be very nice to add this to the package. Has it been maintained at all. Is it tested against 1.3.x?

Cheers,
Marco.

Hi Marco,

you can use it if you want, but as it is based on he original script by others (see my blog post at http://blog.jetztgrad.net/2010/01/updated-bash-completion-script-for-osx-and-grails-1-1-1-2/ for some pointers) you might ask them as well.
I haven't tested it against Grails 1.3.x, so you might need to give it a try. Also it's tested only with Mac OSX. If it does work on Ubuntu, fine, if not, you might want to use the original script (again see my blog post).

Regards,

Wolfgang
