Call External Trigger Output
The Call External Trigger object adds the ability to call a workflow's External Trigger directly. From Alfred 4.1, it is now also possible to set an External Identifier directly on a workflow object.
Take a look at the example workflow called "Call External Trigger" built into the Workflows preferences to see an example in action of how this object can be used to simulate a function / callback.
Why use the "Call External Trigger"?
This has several advantages over the previous way of calling an external trigger using AppleScript.
-
By not using AppleScript, there is no external dependency on the Alfred app name or version.
-
Call External Trigger can be configured to call an external trigger on 'self', meaning no dependency on the current workflow bundle id.
-
Not only can the input argument be passed through to the external trigger, but also all of the current stream variables.
-
Significantly higher performance, as these calls are made internally and directly as per any other workflow stream connection.
