is there a way to specify dotenv_path as a recipe argument?

[willie]

I know I can do just dotenv_path="some.env" recipe, but I'd like it to be obvious for callers when they call just --list.

dotenv-path is a just setting, so it cannot take a recipe parameter directly. On current just, you can make the path visible in just --list with a wrapper recipe:

run env_file:
    @just --dotenv-path {{quote(env_file)}} _run

_run:
    @echo "$TEST_VALUE"

With a POSIX/Bash recipe shell, just --list shows run env_file, and just run test.env loads the chosen file before _run. I verified this on just 1.58.0, including a filename with spaces.
