Activation scripts output is hidden

[nathan-b-flya]

Output written by activation.scripts is not shown when running in pixi run ... or pixi shell.

Minimal example

pixi.toml:

[workspace]
channels = ["conda-forge"]
platforms = ["linux-64"]
requires-pixi = ">=0.71.3"

[activation]
scripts = ["activation.sh"]

[tasks.bonjour]
cmd = "echo Bonjour"

activation.sh:

#!/usr/bin/env bash
echo "-----> ACTIVATION <-----"
# exit 1

---

pixi run ... only shows the output of the task. The activation script output is not shown:

$ pixi run bonjour
✨ Pixi task (bonjour): echo Bonjour
Bonjour

The shell starts, but the activation script output is not shown:

pixi shell

Note: if the activation.sh script fails (exit 1), then -----> ACTIVATION <----- can be seen in the output:

✨ Pixi task (bonjour): echo Bonjour
Error:   × failed to activate environment
  ╰─▶ Failed to run activation script for Default. Status: exit status: 1. Stdout: SHELL=/bin/bash
      ENV_VAR1=...
      ENV_VAR2=...
      ENV_VAR3=...
      ____RATTLER_ENV_START____
      -----> ACTIVATION <-----
      . Stderr: . Script: /usr/bin/env
      echo ____RATTLER_ENV_START____

      export PATH="..."
      export CONDA_*=...
      export PIXI_*=...
      . /path/activation.sh
      echo ____RATTLER_ENV_START____
      /usr/bin/env

Question

Is this the expected behavior?

My use case for this is to have a very lightweight activation script that can print a warning if something is not configured correctly.

Something like:

[activation]
# activation.sh checks that the 'version' and .pixi/setup-version are the same,
# and if not, print a warning suggesting to run 'pixi run setup'
scripts = ["activation.sh"]

[tasks.setup]
depends-on = [
  # a sequence of setup tasks...
  # "setup-something",
  # "setup-whatever",

  # 'version' below has to be incremented everytime the 'setup' task is modified
  # (i.e. a task is added, or an existing sub-task is modified)
  { task = "_setup-mark-done", args = [
    { version = "1" },
  ] },
]
description = "Set of idempotent tasks to setup correctly a workstation."

[tasks._setup-mark-done]
args = ["version"]
cmd = "echo {{ version }}  > .pixi/setup-version"
