A set of Python applications run by a Cylc suite using a shared environment in tasks. This script installs the environment in the suite.
#!/bin/bash
#------------------------------------------------------------------------------
# This script is used by a Python project that is also a Cylc suite.
# An initial task in the suite runs this script to build and install the Python
# project and its environment in a self-contained Conda environment under
# `~/cylc-run/SUITE/share/condaenv/`.
# Subsequent tasks activates this environnment using:
# set +u
# . "${USER_CONDA_PROFILE}"
# conda activate "${SUITE_CONDA_ENV}"
# set -u
# ------------------------------------------------------------------------------
# Note: "conda" does not work with "set -u"
