# Wrapper to run shellcheck with configurations used by swupd project and
# doing necessary changes to validate bats files

# Ignored checks:
#  - SC1008: This shebang was unrecognized.
#    We need to skip this check when processing bats tests because the shebang
#    is not a shell.
# - SC2119: Use foo "$@" if function's $1 should mean script's $1.
#   We need to skip this check because in many ocassions we use functions
#   that are not expecting arguments, but still shellcheck will detect this
#   as error because the show_help which is called from all functions uses $@
