I'm not really a Mac guy so I haven't played with Alfred, but from what I understand it's a launcher of sorts. Will it run executables that are in PATH with supplied arguments? If so, then you should be good to go. Or is there potential for tighter integration? What do you have in mind?

It can run shell commands directly by just prefixing them with > which then opens Terminal and runs the line. What I'd love is an extension (basically just a shell script) that would provide shortcuts to interact with it.

I really loathe 1Password, KeePass, LastPass etc. but what they do is provide me with a FAST way to get to my passwords.

If I could do this with Alfred and this app it would be killer:

pass find ycomb (and then it gives you results that match this and if you hit enter it copies the password to the clipboard) pass add [name/url] [password] pass rm [name/url]

etc. If only I knew how to code this. :)

Just poked at some random extension on the Alfred webpage. Looks like it's two plists and a png inside a zip archive that has a .alfredextension suffix. The plists have a pretty comprehensible XML format, and it should be easy enough to adapt one of these. Copy an existing one, edit the files and tinker around. Shouldn't take very long to do.

Shoot me an email (posted bottom of the page) if you have any success with this.

I haven't slept in a couple of days otherwise I'd take a crack at it myself, but Alfred extensions accept shell scripts. Just typing > in the Alfred bar gives you access to the shell, but I suppose you could use a script for more advanced automation (i.e. take this file/webpage/whatever and autofill).
