Special Variable for Current Working Directory

[is-jonreeves]

It would be great to have a "special variable" that reflects the Current Working Directory for its context. I am finding myself trying to use the sh: echo "$PWD" approach lots and this has some issues when running more than once. Right now I find myself working around this issue alot having to use a combination of the list | join and osClean functions to construct the correct Abs Path for my given context.

Example

If a "special variable" called .CWD was implement then, the following would be possible:

version: '3'

tasks:
  example1:
    cmds:
      - echo "{{.CWD}}"    # ---> C:\Users\Jon\Projects\taskfile-test
  example2:
    dir: ../
    cmds:
      - echo "{{.CWD}}"    # ---> C:\Users\Jon\Projects
  example3:
    dir: ../../
    cmds:
      - echo "{{.CWD}}"    # ---> C:\Users\Jon

Workarounds

There are a few ways I've found of doing this today without a built-in special variable, but they feel unnecessary:

Approach 1: Dynamic Variables (glitched right now)

Note the need to append pairs of '' to each sh: usage.

version: '3'
silent: true

vars:
  CWD: { sh: echo $PWD }

tasks:
  example1:
    cmds:
      - echo "{{.CWD}}"    # ---> C:\Users\Jon\Projects\taskfile-test

  example2:
    dir: ../
    vars:
      CWD: { sh: echo $PWD'' }
    cmds:
      - echo "{{.CWD}}"    # ---> C:\Users\Jon\Projects

  example3:
    dir: ../../
    vars:
      CWD: { sh: echo $PWD'''' }
    cmds:
      - echo "{{.CWD}}"    # ---> C:\Users\Jon

Approach 2: String Processing

Really Repetitive and wouldn't support non-relative paths.

version: '3'
silent: true

vars:
  DIR: './'
  CWD: { sh: pwd }

tasks:
  example1:
    dir: '{{.DIR}}'
    cmds:
      - echo "{{.CWD}}"    # ---> C:\Users\Jon\Projects\taskfile-test

  example2:
    dir: '{{.DIR}}'
    vars:
      DIR: ../
      CWD: '{{list .CWD "/" .DIR | join "" | osClean}}'
    cmds:
      - echo "{{.CWD}}"    # ---> C:\Users\Jon\Projects

  example3:
    dir: '{{.DIR}}'
    vars:
      DIR: ../../
      CWD: '{{list .CWD "/" .DIR | join "" | osClean}}'
    cmds:
      - echo "{{.CWD}}"    # ---> C:\Users\Jon

I wholeheartedly agree with this request. I also believe there should be a special variable for $HOME and $USERNAME.

@andreynering I'm happy to look into this as a first PR if you're interested in adding the functionality. I appreciate any thoughts you have on the matter.

Hi @is-jonreeves and @SwitchedToGitlab,

Yep, I this this makes sense to have! 👍

I think we don't need variables for username and home, though. These are available as environment variables, and do not change between task runs.

I just realized this is proposed before.
