Array function signatures are not obvious from docs or error messages

[agirardeau]

I expected the example Taskfile below to run echo 1 2 3, printing 1 2 3. Instead I get the following error:

template: :1:13: executing "" at <.ARGS>: wrong type for value; expected string; got []interface {}

Perhaps I'm doing something dumb here (misusing the join function?), but it isn't exactly obvious to me what to change.

Example Taskfile

version: '3'

vars:
  ARGS:
    - '1'
    - '2'
    - '3'

tasks:
  exec:
    cmds:
      - echo {{ join .ARGS ' ' }}

Looks like I was just goofing up the join command, it should have been like this:

{{ join " " .ARGS }}

I think I'll leave this open since there are a couple issues highlighted:

• Taskfile docs here refer to the slim-sprig docs, but these aren't sufficient to determine what the right argument order is (since the slim-sprig docs use a pipe operator)
• The error message doesn't indicate where the array variable is rejected - I thought it was telling me that I couldn't declare an array variable at all, rather than saying the first argument of the join function should not be an array
