The decision: command conditionally selects one of multiple potential outcomes.

Syntax

start:
  decision:
    outcome/weekend:
      if@bool: {{'now'|date('l') in ['Saturday','Sunday'] ? 'yes'}}
      then:
        return:
          output: It is the weekend.
    outcome/weekday:
      then:
        return:
          output: It is a weekday.

outcome:

A decision has multiple outcome: commands. The first matching outcome is used.

Each outcome must have a unique name.

An outcome with no if: key always matches, so a bare outcome at the end of a decision is the default – outcome/weekday: above. If no outcome matches and there's no default, none of the then: blocks run, execution continues with the next command, and nothing is logged.

An outcome: can also be used on its own, without a decision, to make a single sequence of commands conditional.
