Clipboard manipulation

# Inspired by Andreas Thuresson here is an Espanso expansion that takes selected/highlighted text, triggered by :case, and offers a few manipulation options.

  - trigger: :case
    label: Modify and paste copied text
    replace: '{{output}}'
    vars:
      - name: clipb
        type: clipboard
      - name: script_choice
        type: choice
        params:
          values:
            - label: Uppercase
              id: echo ""{{clipb}}"" | tr [:lower:] [:upper:]
            - label: Lowercase
              id: echo ""{{clipb}}"" | tr [:upper:] [:lower:]
            - label: Initcase
              id: >-
                awk '{for(i=1;i<=NF;i++) $i=toupper(substr($i,1,1))
                tolower(substr($i,2))}1' <<< "{{clipb}}"

                done
