Hi all,
I made a workflow to allow easily generating filename slugs with Alfred 2. All the details, screenshots and download are here: http://mattgemmell.com/2013/03/26/generating-filename-slugs-with-alfred-2/
'Slugs' are URL/filename-safe versions of strings, commonly used for filenames or in permalinks or CMS systems. So, for example, "Alfred 2 is fab!" would become "alfred-2-is-fab".
My workflow allows setting a default filename-extension (which you can always override on a case-by-case basis), and offers plain, date-prefixed, and date-and-time-prefixed versions of slugs. See the blog post for more.
Hope you find it useful.
Cheers,
-Matt
