Alpaca

Alpaca is a command line utility for building Alfred workflow bundles.

An alpaca project is an alpaca.yml file that defines the workflow, alongside any supporting files, such as scripts or images.

Note: Alpaca is still in the proof-of-concept phase. Huge portions of Alfred functionality are unimplemented.

Schema

Example

This workflow uses a trigger "say" to say words passed as arguments. For example, the user might type "say hello world" into Alfred.

name: Say

objects:
  trigger:
    type: keyword
    config:
      keyword: say
      argument: required
    then: say

  say:
    type: script
    config:
      script:
        content: say {query}
        type: bash

Root Schema

• name The name of the project
• version The version of the project
• author The author of the project (i.e. Jonathan Clem <jonathan@example.com>)
• bundle-id The Alfred workflow bundle ID
• description A short description of the workflow
• readme A longer description of the workflow, seen when users import it
• url A homepage URL for the workflow
• icon A project-relative path to an icon to use for the worflow
• variables A map of variable names and their default values
• object An map of objects in the Alfred workflow. Each key is an object name.
