js.check.sasslint.mk

# Adds a 'check-sasslint' internal target to run 'sasslint'
# over YP_SASSLINT_FILES (defaults to all committed and staged *.sass and *.scss files).
# The 'check-sasslint' target is automatically added to the 'check' target via YP_CHECK_TARGETS.
#
# The sasslint executable is lazy-found inside node_modules/.bin and $PATH.
# The arguments to the sasslint executable can be changed via SASSLINT_ARGS.
#
# For convenience, specific files can be ignored
# via grep arguments given to YP_SASSLINT_FILES_IGNORE:
# YP_SASSLINT_FILES_IGNORE += \
#	-e "^path/to/dir/" \
#	-e "^path/to/file$" \
#
# NOTE transcrypted files are automatically ignored.
