Unknown attribute doc

[Wesztman]

I wanted to have a comment on a handy arg to use for one of my command and stumbled upon the doc attribute, but I keep getting "Unknown attribute doc"

# Use 2>&1 | grep -vE '/ports|selector_events|subprocess|base_events|unix_events|sqlmodel' to silence stuff
[doc('Start backend server locally')]
backend *args:
    uv run flash_backend {{args}}

$ just list

error: Unknown attribute `doc`
  ——▶ justfile:32:2
   │
32 │ [doc('Start backend server locally')]
   │  ^^^

Anyone seeing what I'm doing wrong? 🤔

Just 1.21.0-1 installed via apt on WSL2

The [doc] attribute was added in just 1.27.0. Can you upgrade?

Ahh I see, then I need to pick another package manager right? I see in the readme the Ubuntu24 is stuck on 1.21

I'll just install with uv tool install rust-just instead :)
