vars no longer run sh

[Firesphere]

• Task version: 3.39.2
• Operating system: MacOS 15 & MacOS 14.latest
• Experiments enabled: TASK_X_MAP_VARIABLES=1

Vars, such as this:

version: '3'

tasks:
  test:
    cmds:
      - echo {{.GIT_COMMIT}}
    vars:
      GIT_COMMIT:
        sh: git log -n 1 --format=%h

Now return

$ task test
map[sh:git log -n 1 --format=%h]

instead of the expected evaluated value.

I believe this is expected behavior.

According to Map Variables Experiment, you are using proposal 1 (TASK_X_MAP_VARIABLES=1) which "removes support for the sh and ref keywords in favour of a new syntax"

[Firesphere]

Hmmm, I must've overlooked that when I was looking if it did affect the sh .
Cool, my bad, I'll see how I can fix it a different way :)

@mgbowman is correct. You need to use the $ prefix instead of sh: to execute dynamic variables when TASK_X_MAP_VARIABLES=1. See https://taskfile.dev/next/experiments/map-variables/

Alternatively, you can use TASK_X_MAP_VARIABLES=2 and the behavior of sh: stays the same. Of course, you would need to define any maps using the alternative syntax instead.

Casual reminder that both these experiments could be removed in favor of the other (or neither) in the future. We're still looking for feedback on both from users in #1585.
