Huh? What!?
HackPad is a web application allowing for collaborative document editing and it's awesome.
Alfred is a Mac OS X productivity application that makes all kinds of things just a keystroke away and it's also awesome!
You can install the Alfred workflow by downloading the HackPad.alfredworkflow file and opening it with Alfred.
Invoke Alfred and type hp followed by whatever text you want to search for in HackPad. Alfred will start to list the relevant pads, select one and hit enter and it'll open that pad in your browser.
This workflow needs to know your HackPad API ID and Secret Key in order to make API queries on your behalf. This information can be found by accessing your account settings on the HackPad site.
Trigger Alfred and enter the text hpsettings to trigger the configuration commands. Then type one of id, key or url followed by a space and the value you would like to set for that option.
Note: If you use a custom hackpad URL like lullabot.hackpad.com, you will also need to enter the url into the settings in order for this workflow to work.
The complete command might look something like hpsettings id MYAPIID, then hit enter. If it works, you should see a message displayed on the screen.
