Alfred URI Handler
This workflow has one command "au:install". Once you run it, a URI handler for Alfred will be installed. This is used to trigger external triggers in any workflow. The format is:
alfreduri://com.apple.AppleScript.AlfredURIhandler?wf=<workflow Bundle ID>&arg=<arguments>&ext=<external trigger name>
The arguments should be URI encoded (ie: no spaces, but %20 instead). If you update the workflow, you have to re-apply the handler. Also, do not delete the workflow or the functionality will be removed.
I use it to make action links in FoldingText to trigger actions in Alfred.
There is also a "search=<search args>" to open the Alfred prompt with a query. It now works. If you already downloaded and installed the handler, please do it again.
