Feature Request - Test directory exists

[yonas]

Existing workaround

version: 3

vars:
  tmpdir: /some/path

tasks:
  default:
    preconditions:
      - sh: test -d "{{ .tmpdir }}"
        msg: "Temp directory must exist"
    requires:
      vars:
        - tmpdir
    dir: '{{.tmpdir}}'
    cmds:
      - echo $PWD

Method #1

The existing workaround would be shortened to:

version: 3

vars:
  tmpdir: /some/path

tasks:
  default:
    dir:
      path: '{{.tmpdir}}'
      required: true
    cmds:
      - echo $PWD

Note

• requires is replaced by dir.required
• preconditions check, error message, and program aborting is replaced by dir.required

Using dir as a simple string would continue to work for existing Taskfiles

dir.required defaults to false

Method #2

The existing workaround would be shortened to:

version: 3

vars:
  tmpdir: /some/path

tasks:
  default:
    required-dir: '{{.tmpdir}}'
    cmds:
      - echo $PWD

I prefer method #2, as it's more compact.

With the current method of using sh, which is not a workaround, you can construct any kind of test as a precondition: directory exists, directory not exists, file exists, file not exists ... anything which the shell can do (which is everything).

Now consider the suggestion, which can do one thing, and one thing only. Not ideal.

[yonas]

This feature is not mutually exclusive to precondition.

It actually is ideal since it only does one thing with very little typing.
