+#!/bin/sh
+# Compatible with ranger 1.6.0 through 1.7.*
+#
+# This script searches image files in a directory, opens them all with sxiv and
+# sets the first argument to the first image displayed by sxiv.
+#
+# This is supposed to be used in rifle.conf as a workaround for the fact that
+# sxiv takes no file name arguments for the first image, just the number.  Copy
+# this file somewhere into your $PATH and add this at the top of rifle.conf:
+#
+#   mime ^image, has sxiv, X, flag f = path/to/this/script -- "$@"
+#
+# Implementation notes: this script is quite slow because of POSIX limitations
+# and portability concerns. First calling the shell function 'abspath' is
+# quicker than calling 'realpath' because it would fork a whole process, which
+# is slow. Second, we need to append a file list to sxiv, which can only be done
+# properly in two ways: arrays (which are not POSIX) or \0 sperated
+# strings. Unfortunately, assigning \0 to a variable is not POSIX either (will
+# not work in dash and others), so we cannot store the result of listfiles to a
+# variable.
