convert env var defined in .env as variable

[kernel164]

os: macos
Task version: 3.0.0

.env

XYZ=1

Taskfile.yml

version: "3"
dotenv: [".env"]
vars:
  XYZ: 
    sh: echo "$XYZ"
tasks:
  test:
    cmds: 
      - echo "{{ .XYZ }}" # is empty always
      - echo "$XYZ" # echo 1
      #- echo "{{ split "." $XYZ }}" # fails can't use env var inside go template

Output:

task test
task: echo ""

task: echo "$XYZ"
1

Hi @kernel164,

Thanks for reporting, this is indeed a bug

[duboiss]

I don't really know if this has a relation but:

APP_ENV=dev

dotenv: ['.env']

env:
    ...

vars:
    ENV: $APP_ENV

tasks:
    hmm:
        cmds:
            - echo $APP_ENV

"APP_ENV": executable file not found in $PATH

Same if I replace echo $APP_ENV by echo "{{.ENV}}" or echo {{.ENV}}.

I need to initialize a global variable with an .env value (default bahavior).
Because this Tasfkile.yml will be shared by several people, some will want to assign a fixed value like "dev" or "prod" instead of basing it on the .env APP_ENV.

I believe I have the same issue as well. Looks like environment variables are not usable within vars.
Also variables defined in .env files cannot be used within

env:
    INCREMENTAL: $APP_ENV/build

where .env contains: APP_ENV=/home/path

This is quite crucial if you only want to have environment specific variables in .env and all variables derived from that in the script.

Otherwise you'll have to do this in the .env file:

APP_ENV=/home/path
INCREMENTAL=$APP_ENV/build

Fixed in master

Thanks a lot for working on this! I've just tested this and looks like it is broken in the way I'm trying to use this.

this works:

.env:

TEST=/home/test/.local/bin

Taskfile.yml:

version: '3'

dotenv: ['.env']

env:
  TEST1: X$TEST/.local/bin

tasks:
  test:
    cmds:
      - echo $TEST1

However when removing the X from the TEST1: line, it breaks.

I get the following error message:

stat /home/<...>/Developer/test/TEST/.local/bin: no such file or directory
task: Command "TEST/.local/bin" in taskvars file failed: exit status 127

I did not dig deep in the code to understand why this is happening, maybe you got an idea.

Thanks in advance!
