f3: fork of fff (Fucking Fast File-Manager)

Most text in the following is the original text of @dylanaraps repo. I changed only things regarded to image preview with sixel

Almost all credits go to @dylanaraps!

• It's Fucking Fast 🚀
• Minimal (only requires bash and coreutils)
• Smooth Scrolling (using vim keybindings)
• Works on Linux, BSD, macOS, Haiku etc.
• Supports LS_COLORS!
• File Operations (copy, paste, cut, ranger style bulk rename, etc)
• Instant as you type search
• Tab completion for all commands!
• Automatic CD on exit (see setup)
• Works as a file picker in vim/neovim (link)!
• Display images with sixel and chafa!
• Supports $CDPATH.

  • Not needed on macos and Haiku.
  • Customizable (if not using xdg-open): $FFF_OPENER.

Dependencies for image display

• chafa
• a terminal which can display sixel graphics
• xdotool for X.
• fbset for the framebuffer.

Installation

Manual

1. Download f3.
   • Git: https://codeberg.org/lukeflo/f3
2. Change working directory to f3.
   • cd f3
3. Run make install inside the script directory to install the script.
   • El Capitan: make PREFIX=/usr/local install
   • Haiku: make PREFIX="$(finddir B_USER_NONPACKAGED_DIRECTORY)" MANDIR='$(PREFIX)/documentation/man' DOCDIR='$(PREFIX)/documentation/fff' install
   • OpenIndiana: gmake install
   • MinGW/MSys: make -i install
   • NOTE: You may have to run this as root.

NOTE: fff can be uninstalled easily using make uninstall. This removes all of files from your system.

CD on Exit

Bash and Zsh

# Add this to your .bashrc, .zshrc or equivalent.
# Run 'fff' with 'f' or whatever you decide to name the function.
f() {
    fff "$@"
    cd "$(cat "${XDG_CACHE_HOME:=${HOME}/.cache}/fff/.fff_d")"
}

Fish

# Add this to you config.fish or equivalent.
# Fish don't support recursive calls so use f function
function f
    fff $argv
    set -q XDG_CACHE_HOME; or set XDG_CACHE_HOME $HOME/.cache
    cd (cat $XDG_CACHE_HOME/fff/.fff_d)
end

Customizing the keybindings.

Keybindings

This is the list of full keybindings along with their default values. You only need to modify the keybindings that you'd like to change from the default. fff will run perfectly fine without any of these defined.

### Moving around.

# Go to child directory.
export FFF_KEY_CHILD1="l"
export FFF_KEY_CHILD2=$'\e[C' # Right Arrow
export FFF_KEY_CHILD3=""      # Enter / Return

# Go to parent directory.
export FFF_KEY_PARENT1="h"
export FFF_KEY_PARENT2=$'\e[D' # Left Arrow
export FFF_KEY_PARENT3=$'\177' # Backspace
export FFF_KEY_PARENT4=$'\b'   # Backspace (Older terminals)

# Go to previous directory.
export FFF_KEY_PREVIOUS="-"

# Search.
export FFF_KEY_SEARCH="/"

# Spawn a shell.
export FFF_KEY_SHELL="!"

# Scroll down.
export FFF_KEY_SCROLL_DOWN1="j"
export FFF_KEY_SCROLL_DOWN2=$'\e[B' # Down Arrow

# Scroll up.
export FFF_KEY_SCROLL_UP1="k"
export FFF_KEY_SCROLL_UP2=$'\e[A'   # Up Arrow

# Go to top and bottom.
export FFF_KEY_TO_TOP="g"
export FFF_KEY_TO_BOTTOM="G"

# Go to dirs.
export FFF_KEY_GO_DIR=":"
export FFF_KEY_GO_HOME="~"
export FFF_KEY_GO_TRASH="t"
export FFF_KEY_REFRESH="e"

### File operations.

export FFF_KEY_YANK="y"
export FFF_KEY_MOVE="m"
export FFF_KEY_TRASH="d"
export FFF_KEY_LINK="s"
export FFF_KEY_BULK_RENAME="b"

export FFF_KEY_YANK_ALL="Y"
export FFF_KEY_MOVE_ALL="M"
export FFF_KEY_TRASH_ALL="D"
export FFF_KEY_LINK_ALL="S"
export FFF_KEY_BULK_RENAME_ALL="B"

export FFF_KEY_PASTE="p"
export FFF_KEY_CLEAR="c"

export FFF_KEY_RENAME="r"
export FFF_KEY_MKDIR="n"
export FFF_KEY_MKFILE="f"
export FFF_KEY_IMAGE="i" # display image with w3m-img

### Miscellaneous

# Show file attributes.
export FFF_KEY_ATTRIBUTES="x"

# Toggle executable flag.
export FFF_KEY_EXECUTABLE="X"

# Toggle hidden files.
export FFF_KEY_HIDDEN="."

Disabling keybindings.

You can't unset keybindings by making their value ''. What you need to do is change their value to off.

Example:

# KEY_GO_TRASH was bound to 't', now its unset.
export FFF_KEY_GO_TRASH="off"

# KEY_MKFILE is now set to 't' and its original
# keybinding is also unset 'f'.
export FFF_KEY_MKFILE="t"

Dealing with conflicting keybindings.

When rebinding a key in fff make sure you don't have two bindings with the same value. You can avoid this by setting the other conflicting key-binding to something else or by changing its value to off.

How to figure out special keys.

Below is a tiny script I've written which will tell you the exact value to use. It automates the deciphering of special key escape sequences to the exact value fff needs. Save this to a file and run it. Give it a key-press and it'll spit out the exact value needed.

#!/usr/bin/env bash
# Output the key-binding values for 'fff'.
key() {
    case "$1" in
        # Backspace.
        $'\b'|$'\177')
            printf '%s\n' "key: \$'\\b' or \$'\\177'"
        ;;

        # Escape Sequences.
        $'\e')
            read -rsn 2
            printf '%s %q\n' "key:" "${1}${REPLY}"
        ;;

        # Return / Enter.
        "")
            printf '%s\n' "key: \" \""
        ;;

        # Everything else.
        *)
            printf '%s %q\n' "key:" "$1"
        ;;
    esac
}

read -srn 1 && key "$REPLY"

Using fff in vim/neovim as a file picker
