+# vim: ft=cfg
+#
+# This is the configuration file of "rifle", ranger's file executor/opener.
+# Each line consists of conditions and a command.  For each line the conditions
+# are checked and if they are met, the respective command is run.
+#
+# Syntax:
+#   <condition1> , <condition2> , ... = command
+#
+# The command can contain these environment variables:
+#   $1-$9 | The n-th selected file
+#   $@    | All selected files
+#
+# If you use the special command "ask", rifle will ask you what program to run.
+#
+# Prefixing a condition with "!" will negate its result.
+# These conditions are currently supported:
+#   match <regexp> | The regexp matches $1
+#   ext <regexp>   | The regexp matches the extension of $1
+#   mime <regexp>  | The regexp matches the mime type of $1
+#   name <regexp>  | The regexp matches the basename of $1
+#   path <regexp>  | The regexp matches the absolute path of $1
+#   has <program>  | The program is installed (i.e. located in $PATH)
+#   env <variable> | The environment variable "variable" is non-empty
+#   file           | $1 is a file
+#   directory      | $1 is a directory
+#   number <n>     | change the number of this command to n
+#   terminal       | stdin, stderr and stdout are connected to a terminal
+#   X              | A graphical environment is available (darwin, Xorg, or Wayland)
+#
+# There are also pseudo-conditions which have a "side effect":
+#   flag <flags>  | Change how the program is run. See below.
+#   label <label> | Assign a label or name to the command so it can
+#                 | be started with :open_with <label> in ranger
+#                 | or `rifle -p <label>` in the standalone executable.
+#   else          | Always true.
+#
+# Flags are single characters which slightly transform the command:
+#   f | Fork the program, make it run in the background.
+#     |   New command = setsid $command >& /dev/null &
+#   r | Execute the command with root permissions
+#     |   New command = sudo $command
+#   t | Run the program in a new terminal.  If $TERMCMD is not defined,
+#     | rifle will attempt to extract it from $TERM.
+#     |   New command = $TERMCMD -e $command
+# Note: The "New command" serves only as an illustration, the exact
+# implementation may differ.
+# Note: When using rifle in ranger, there is an additional flag "c" for
+# only running the current file even if you have marked multiple files.
