{{.TASK}} remains in task listing

[MarioSchwalbe]

Versions

• Task version: v3.14.0
• Operating System: Mac OS X 10.15.7

Example Taskfile showing the issue

version: '3'

tasks:
  DoesNotWork:
    desc:  DoesNotWork
    label: '{{.TASK}}'
    cmds:
      - echo "PARAM = '{{ .PARAM | trim }}'"

  DoesWork:
    desc:  DoesWork
    label: '{{.TASK}}'
    cmds:
      - echo "PARAM = '{{ .PARAM | default "" | trim }}'"

Run:

$ task -l
task: Available tasks for this project:
* {{.TASK}}: 	DoesNotWork
* DoesWork: 	DoesWork

Notes:

• Both tasks are intended to be called from the command-line but also embedded within other tasks by passing their task name as variable TASK.
• The task DoesNotWork fails if run without the parameter (which is expected):

  $ task DoesNotWork
  template: :1:27: executing "" at <trim>: invalid value; expected string
  

  The task DoesWork would work due to the provided default.

However, this should not affect the output of task -l. Or is this a hidden feature to validate the correctness of tasks? Like: If it looks like {{.TASK}}, some default is missing.

Hi @MarioSchwalbe, thanks for reporting this bug.

IIRC templating is skipped completely for --list.

We already have a more lightweight variation of the function that does templating (which is faster because it skips shell commands from running). We could consider doing that for this use case as well.

It seems that this is not a problem anymore on the current release.

I'm closing this. If anyone continue to experience this issue, let me know.
