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.

Installation

Download the latest release, or:

$ go get github.com/jclem/alpaca

Usage

alpaca pack <dir>

Pack an Alpaca project into an Alfred workflow. The workflow will be output into the current directory.

$ alpaca pack .

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
