# Remove packages from a conda channel. See the
# rules/fsl-ci-management-rules.yml:clear-public-channel and
# clear-private-channel jobs.
# Exactly one of the CLEAR_ALL, CLEAR_OLD, or PATTERN variables must be
# set - if not, or if more than one of these variables are set, the job
# exits without doing anything.
# If the CLEAR_ALL variable is set, *all* packages are removed.
# If the CLEAR_OLD variable is set, all except the most recent version
# of each package is removed.
# The PATTERN variable may be a semi-colon- separated list of glob-style
# patterns which indicate the packages to be deleted. For example, to
# remove all packages starting with "abc-", and all packages with
# "-misc" in their name:
# PATTERN="abc-*;*-misc*"
# Each pattern is matched against the conda package file names in each
# of the channel platform directories (i.e. noarch, linux-64, osx-64,
# etc), and all matching package files are removed.
# The DRY_RUN variable has a default value of "true". It must be
# manually set to "false" in order for packages to be removed. When
# DRY_RUN is "true", no package files are removed - instead, the package
# files that would be removed are printed to standard output.
