Hello
What command do you run ? Because it works fine when I run task database

IE : DB and NAME are empty (define but empty)

Hey @vmaerten

I see I messed up the reproducer. My bad 🙁 I've updated the example below.

version: '3'

tasks:
  database:
    desc: Open database
    silent: true
    vars:
      NAME: '{{.n}}'
    requires:
      vars:
        - DB: '{{.d}}'
    cmds:
      - |
        echo "{{.DB}}-{{.NAME}}"

IE : DB and NAME are empty (define but empty)

Maybe my misunderstanding comes from the misuse of vars and requires. I want to use variables with a shortcut (like {{.n}} and {{.d}}), where some are required and some are not. In the above NAME is optional, but DB should be required, but I want to call it with task database / task database d=1, which should output 1- (in n is not provided).

Long story short: I cannot use shortcuts like {{.d}} for required variables?

requires.vars is a list of string, it does not accepte any values.
This is incorrect :

    requires:
      vars:
        - DB: '{{.d}}'

This is correct :

    requires:
      vars:
        - DB

About what you are trying to achieve, you can do that :

version: '3'

tasks:
  database:
    desc: Open database
    silent: true
    vars:
      DB: '{{.d}}'
      NAME: '{{.n}}'
    requires:
      vars:
        - d
    cmds:
      - |
        echo "{{.DB}}-{{.NAME}}"

You define two variables DB that will take value from d and NAME that will take value from n
And you also specify that d is required.

Ah okay, I didn't think of trying to use the shortcut value in the requires.vars. I was under the false assumption that requires would use the actual vars name instead of the shortcut value.

Thank you very much for the clarification. 👍
