Pacman install optional dependencies

Guys is there a way of installing packages using pacman in such a way that it prompts you about all the optional dependencies before installing just like pamac does?

I think it writes it during the installation process.

You could probably write a wrapper using ``expac -S '%O\n' $pkg''. You might want to take care of cases where there is more than one package of a single name.

That should be a small %o in the expac format. And there'd be no need to deduplicate the output as pacman will handle this itself:

# install all optional dependencies (as explicit) for pkgs 1-3 that are already installed:
expac -Q %o $pkg1 $pkg2 $pkg3 | pacman -S -
# install package and all of it's optional dependencies:
expac -S "%n %o" $pkg | pacman -S -

If prompts for individual optional dependencies are desired, some more complexity is required, i believe.

Such as

typeset -a os
for o in `expac -S '%o\n' $pkgs`
do
  read -p "Install ${o}? " r
  [[ ${r,,} =~ ^y(|e|es)$ ]] && os+=( $o )
done

pacman -S $pkgs ${os[@]}

This assumes that no package name exists twice in the configured repositories.

A capital %O could be used to additionally list the respective reason on each prompt.

Edit: Fixed usage of whole array. Alternatively, a normal variable with spaces would suffice.
