add pacman fuzzy finder

[Saad-Dev-8]

just like 'yayf' i just created a pacman fuzzy finder named 'pacf'.
i optimize it to be fast and lightweight plus it has multi selection for installing multiple packages
here is the pacman fuzzy finder:

fuzzy_pacman() {
  selected=$(comm -23 <(pacman -Slq | sort) <(pacman -Qq | sort) |
    cat - <(pacman -Qq | awk '{printf "%-30s \033[32m[installed]\033[0m\n", $1}') |
    fzf --ansi --multi --layout=reverse \
      --preview '
        pacman -Si $(awk "{print \$1}" <<< {}) 2>/dev/null | \
        bat --plain --language=ini --style=plain --color=always | \
        sed -r "
          s/(Installed Size|Name|Version|Depends On|Optional Deps|Maintainer|Repository|Licenses|URL)/\x1b[96;1m\1\x1b[0m/g
        "
      ' --preview-window=right:60% | awk '{print $1}' | paste -sd " " -)

  if [[ -n "$selected" ]]; then
    echo -e "\033[32mInstalling packages:\033[0m $selected"
    sudo pacman -S ${selected// / }
  else echo "No packages selected."; fi
}

alias pacf='fuzzy_pacman'

Works great, I compacted it a bit and added some safety with 'command pacman' for example. (also some opinionated changes).

fuzzy_pacman(){ 
  local sel SHELL=bash; sel=$(comm -23 <(command pacman -Slq | sort) <(command pacman -Qq | sort) |
    cat - <(command pacman -Qq | awk '{printf "%-30s \033[32m[installed]\033[0m\n", $1}') |
    fzf --ansi -m --style=full --cycle --border --height=~100% --inline-info -0 --layout=reverse-list \
      --preview '
        command pacman -Si $(awk "{print \$1}" <<< {}) 2>/dev/null | \
        command bat -p --language=ini --color=always | \
        sed -r "s/(Installed Size|Name|Version|Depends On|Optional Deps|Maintainer|Repository|Licenses|URL)/\x1b[96;1m\1\x1b[0m/g"
      ' --preview-window=right:60%:wrap | awk '{print $1}' | paste -sd " " -)
  [[ -n $sel ]] && { printf '%b\n' "\e[32mInstalling packages:\e[0m $sel"; \
    sudo pacman -S ${sel// / } --noconfirm --needed; } || printf '%s\n' "No packages selected."
}
alias pacf='fuzzy_pacman'

here it is in skim/sk

fusky_pacman(){ 
  local sel SHELL=bash; sel=$(comm -23 <(command pacman -Slq | sort) <(command pacman -Qq | sort) |
    cat - <(command pacman -Qq | awk '{printf "%-30s \033[32m[installed]\033[0m\n", $1}') |
    sk --ansi -m --cycle --border --inline-info --height=~100% -0 --layout=reverse-list \
      --preview '
        command pacman -Si $(awk "{print \$1}" <<< {}) 2>/dev/null | \
        command bat -p --language=ini --color=always | \
        sed -r "s/(Installed Size|Name|Version|Depends On|Optional Deps|Maintainer|Repository|Licenses|URL)/\x1b[96;1m\1\x1b[0m/g"
      ' --preview-window=right:60%:wrap | awk '{print $1}' | paste -sd " " -)
  [[ -n $sel ]] && { printf '%b\n' "\e[32mInstalling packages:\e[0m $sel"; \
    sudo pacman -S ${sel// / } --noconfirm --needed; } || printf '%s\n' "No packages selected."
}
alias pacsk='fusky_pacman'

the ~ in height is for auto detecting your terminal size, -m is just shortened --multi, I personally prefer reverse-list, -0 is for exiting when no results are there
