Love the coffee icon!<p>Growl notifications are also available in Jitter, my custom alternative to `coffee -cwo`: <a href="https://github.com/TrevorBurnham/jitter" rel="nofollow">https://github.com/TrevorBurnham/jitter</a><p>Jitter has a couple of other little perks: It watches for new source files as well as changes to existing source files; it can run tests after each compilation; and it never replaces JS files with identical JS files (keeping timestamps intact).
One alternative that works for me is vim, with the syntastic plugin (<a href="https://github.com/scrooloose/syntastic" rel="nofollow">https://github.com/scrooloose/syntastic</a>). It comes with a coffee syntax checker.
