Espanso Integration

In day to day use I use it within espanso. E.g. add this to your .yaml:

  - regex: ":=\\((?P<input>.*)\\)"
    replace: "{{solved}}"
    vars:
      - name: "solved"
        type: "shell"
        params: 
          cmd: "stcalc %ESPANSO_INPUT%"
          shell: "cmd"   

This will turn :=(12 + 23) into 35.
