Setting environment variables in pixi tasks

[ashah03]

Hi! I'd like to be able to set environment variables from a file within pixi tasks, e.g.

[tool.pixi.tasks]
creds = { cmd = "export $(cat env/creds.env | xargs)" }
train = { cmd = "python train.py", depends-on = ["creds"]}

But when I do this, the files are not exported to the shell running train, so I'm having to do

[tool.pixi.tasks]
train = { cmd = "export $(cat env/creds.env | xargs) && python train.py"}

Is there any other workaround? Each of my many tasks will need credentials so don't want to have to copy paste that portion if it can be avoided.

You can add a script to the activation that exports these variables.

activate.sh

export $(cat env/creds.env | xargs)

pyproject.toml

[tool.pixi.activation]
scripts = ["activate.sh"]

The environment isn't persisted over the tasks using the depends-on.
