# Use non-default path for file preview script?
# ranger ships with scope.sh, a script that calls external programs (see
# README.md for dependencies) to preview images, archives, etc.
set preview_script ~/.config/ranger/scope.sh
# Use the external preview script or display simple plain text or image previews?
set use_preview_script true
# Be aware of version control systems and display information.
set vcs_aware false
# Use one of the supported image preview protocols
set preview_images true
# Set the preview image method. Supported methods:
#
# * w3m (default):
# Preview images in full color with the external command "w3mimgpreview"?
# This requires the console web browser "w3m" and a supported terminal.
# It has been successfully tested with "xterm" and "urxvt" without tmux.
#
# * iterm2:
# Preview images in full color using iTerm2 image previews
# (http://iterm2.com/images.html). This requires using iTerm2 compiled
# with image preview support.
#
# This feature relies on the dimensions of the terminal's font. By default, a
# width of 8 and height of 11 are used. To use other values, set the options
# iterm2_font_width and iterm2_font_height to the desired values.
#
# * terminology:
# Previews images in full color in the terminology terminal emulator.
# Supports a wide variety of formats, even vector graphics like svg.
#
# * urxvt:
# Preview images in full color using urxvt image backgrounds. This
# requires using urxvt compiled with pixbuf support.
#
# * urxvt-full:
# The same as urxvt but utilizing not only the preview pane but the
# whole terminal window.
#
# * kitty:
# Preview images in full color using kitty image protocol.
# Requires python PIL or pillow library.
# If ranger does not share the local filesystem with kitty
# the transfer method is changed to encode the whole image;
# while slower, this allows remote previews,
# for example during an ssh session.
# Tmux is unsupported.
#
# * ueberzug:
# Preview images in full color with the external command "ueberzug".
# Images are shown by using a child window.
# Only for users who run X11 in GNU/Linux.
set preview_images_method kitty
# Which colorscheme to use? These colorschemes are available by default:
# default, jungle, snow, solarized
set colorscheme default
# Draw borders around columns? (separators, outline, both, or none)
# Separators are vertical lines between columns.
# Outline draws a box around all the columns.
# Both combines the two.

# 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.
