# FZF navigation/previewing/selection plugin for Clifm
# Written by L. Abramovich
# License: GPL2+

# Description: Navigate the filesystem (including files preview and
# selection) with FZF.

# Previews are shown by just hovering on the file. Each generated preview,
# provided it needs to be converted before (e.g. .gif, .pdf and .docx files),
# is cached as image file(s) (using hashes as names) in
# $HOME/.cache/clifm/previews to avoid subsequent convertions and speed up
# thus the whole process.

# A separate script is used for file previewing:
# $HOME/.config/clifm/plugins/BFG.sh

# A configuration file is available:
# $HOME/.config/clifm/plugins/BFG.cfg
# or
# $XDG_DATA_DIRS/clifm/plugins/BFG.cfg (usually /usr/local/share/clifm/plugins/BFG.cfg)

# How the files previewer works?
# 1. The config file is read looking for predefined options and previewing
#     applications.
# 2. Options not defined in the config file are set to the default value.
#     If no opening application for a given file type was defined in the
#     config file, the system is scanned for available applications.
#    NOTE: Determining previewing applications is done only once, when
#     when the fzfnav.sh script starts, instead of each time a file is
#     hovered, which saves a significant amount of time.
# 3. Export this info as environment variables.
# 4. Launch FZF using the BFG.sh script to generate files preview using
#     the information previosuly gathered. This script only takes care of
#     determining file types and executing the corresponding previewing
#     application.

HELP="USAGE
  Type in the prompt to filter the current list of files. Regular expressions are \
allowed.

  Use the --edit command line option to edit the configuration file.

KEYBINDINGS

  * Left: Change to parent directory
  * Right/Enter: Change to the highlighted directory or open the highlighted file
  * Home/end: Change to first/last file in the files list
  * TAB: Select currently highlighted file
  * Ctrl-s: Select all
  * Ctrl-d: Deselect all
  * Ctrl-t: Toggle selection
  * Alt-s: Confirm selection (do it before changing directory or the current selection will be lost)
  * Shift-up/down: Move one line up/down in the preview window
  * Alt-up/down: Move to the beginning/end in the preview window
  * Ctrl-q/Ctrl-c: Change to the last visited directory and exit
  * Esc: Cancel and exit"
