+#!/usr/bin/env sh
+# 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
+
+# Meanings of exit codes:
+# code | meaning    | action of ranger
+# -----+------------+-------------------------------------------
+# 0    | success    | success. display stdout as preview
+# 1    | no preview | failure. display no preview at all
+# 2    | plain text | display the plain content of the file
+# 3    | fix width  | success. Don't reload when width changes
+# 4    | fix height | success. Don't reload when height changes
+# 5    | fix both   | success. Don't ever reload
+# 6    | image      | success. display the image $cached points to as an image preview
+# 7    | image      | success. display the file directly as an image
