# Helpers for defining environment variables for CircleCI.
|
|
#
|
|
# In CircleCI, each step runs in a new shell. The way to share ENV variables across steps is to
|
|
# export them from `$BASH_ENV`, which is automatically sourced at the beginning of every step (for
|
|
# the default `bash` shell).
|
|
#
|
|
# See also https://circleci.com/docs/2.0/env-vars/#using-bash_env-to-set-environment-variables.
