Global vars: & env: are not interpolated in tasks: desc: fields

[itnok]

• Task version: 3
• Operating system: darwin / macOS
• Experiments enabled: No
• Example Taskfile.yaml to reproduce the issue:

---
version: "3"

env:
  SOME_STATIC_ENV: "ful"
  SOME_DYNAMIC_ENV:
    sh: echo "beauti"

vars:
  SOME_STATIC_VAR: "o "
  SOME_DYNAMIC_VAR:
    sh: echo "hell"

tasks:
  not-helpful:
    desc: {{ .SOME_DYNAMIC_VAR }}{{ .SOME_STATIC_VAR }}{{ .SOME_DYNAMIC_ENV }}{{ .SOME_STATIC_ENV }} {{ OS }} world
    cmds:
      - true

Expected output:

hello beautiful darwin world

Output:

hellful darwin world

Variable interpolation works well, but it seems that desc: does not support interpolation for neither vars: or env: variables that are "dynamically" generated (or more likely vars: and env: are not computed before desc: interpolation happens?). I am looking for this to try to make my tasks a little more generic... (similar to #276 but not limited to Golang templates)

This same issue exists with both the desc: and prompt: fields. I'd like to be able to run something like:

ENVIROMENT=prod task deploy

But the prompt comes back looking like:

You are about to deploy to ${ENVIROMENT}, continue? [y/N]

Instead of the desired:

You are about to deploy to prod, continue? [y/N]

@itnok in desc (and prompt), you can interpolate static variables but not dynamic variables. This is intentional, mainly for better performance, as this command is used for autocomplete.

@clarson99 this is working actually :

version: "3"

tasks:
  deploy
    prompt: 'You are about to deploy to {{.ENV}}'
    cmds:
      - true
