# ranger supports enhanced previews.  If the option "use_preview_script"
# is set to True and this file exists, this script will be called and its
# output is displayed in ranger.  ANSI color codes are supported.

# NOTES: This script is considered a configuration file.  If you upgrade
# ranger, it will be left untouched. (You must update it yourself.)
# Also, ranger disables STDIN here, so interactive scripts won't work properly
