[3.39.0] Environment variable seen as command

[Firesphere]

• Task version:
  3.39.0

• Operating system:
  MacOS Sonoma 14.6.1

• Experiments enabled:
  TASK_X_MAP_VARIABLES=1

Having the following .env.local file:

PROJECTS='~/Projects/test-projects/'

And the following task:

tasks:
  project:binaries:watch:*: # This task is in the root because of watcher issues outside of the root Taskfile
    aliases: [s:b:w:*]
    vars:
      DAEMON: '{{index .MATCH 0}}'
      CALLTASK: 'demo:supervisor:reload:{{.DAEMON}}'
    env:
      BASEFOLDER: ${PROJECTS}
    sources: 
      - '{{.BASEFOLDER}}/build/**/*'
      - '{{.BASEFOLDER}}/src/**/*'
    watch: true
    cmds:
      - task: '{{.CALLTASK}}'

And the call copies the build binary to the docker container, and runs a supervisor reload

On 3.38.x, this was working fine.

On 3.39.0, I get the following error:

"{PROJECTS}": executable file not found in $PATH
task: Command "{PROJECTS}" failed: exit status 127

Same when using vars instead of env, or trying to do echo ${PROJECTS} as a command. Each option tells me the command {PROJECTS}

Hi !
Can you try to provide a minimal reproduction example ?

I am on linux (and Zsh) and it seems to work fine :

❯ TASK_X_MAP_VARIABELS=1 taskd -d ../reproductions/github/1812 project:binaries:watch:test                                                          
task: Started watching for tasks: project:binaries:watch:test
task: Task "demo:supervisor:reload:test" does not exist
task: Failed to run task "project:binaries:watch:*": task: Task "demo:supervisor:reload:test" does not exist

Here you go, I am pretty sure this should cover the entire scenario :)

When running task prj:bin:w:test (I've shortened the task naming, for easier typing :D ), I get

$: TASK_X_MAP_VARIABLES=1 task prj:bin:w:test             
task: Started watching for tasks: prj:bin:w:test
"{PROJECTS}": executable file not found in $PATH
task: Command "{PROJECTS}" failed: exit status 127

I just upgraded to MacOS 15.0.0, but it still occurs.

With TASK_X_MAP_VARIABLES=1, the $ is used to declare dynamic variable (cf : https://taskfile.dev/experiments/map-variables/#dynamic-variables)
So, with map variable experiment proposal 1 it's the expected behavior.

Please note that this is an experiment and it may change in the future.

I am not sure with you need env but according to your example, this should work :

tasks:
  project:binaries:watch:*: # This task is in the root because of watcher issues outside of the root Taskfile
    aliases: [s:b:w:*]
    vars:
      DAEMON: '{{index .MATCH 0}}'
      CALLTASK: 'demo:supervisor:reload:{{.DAEMON}}'
      BASEFOLDER:  '{{.PROJECTS}}'
    sources: 
      - '{{.BASEFOLDER}}/build/**/*'
      - '{{.BASEFOLDER}}/src/**/*'
    watch: true
    cmds:
      - task: '{{.CALLTASK}}'
