Adds (mostly) complete -Sl support. While pacman will also print the
version number for the package, packages.gz does not give version
numbers. Using -Si to fetch all that data would also be unthinkable.
Instead of just missing out the version number yay will print
"unknown-version". This is so that tools that expect a version number do
not break.
This makes more sense and falls in line with the structs value which has
always been cleanafter. afterclean is still useable for compatibility
but is undocumented.
Normaly we only pass --config to pacman if the user specifies it on the
command line. Otherwise we let pacman use it's default config location.
If the user has changed pacmanconf in Yay's config file then this could
cause a miss match between the config we use to init alpm and the config
pacman is using.
Bash seperates on whitespace, so the fish completion file
actually works for bash and zsh. So remove the concept of shells
entirley and just use the singular aur_sh.cache file.
If for some reason output without the repository data is needed, the
user could always just pipe it into awk like so
`yay -Pc | awk '{print $1}'`. Or perhaps a --quiet option could be added
where yay will strip the output itself.
The completion cache now updates when installing AUR packages. This is
done as a goroutine with no wait groups. This ensures the program will
never hang if there is a problem.
The completion is stil updated during -Pc but as long as an AUR package
has been installed recently it should not need to update.
The cache will now also wait 7 days instead of 2 before refreshing.
A refresh can be forced using -Pcc.
Currently we do not handle -Sp, this leads to yay trying a proper
install and failing. So instead pass it to pacman and exit. Ideally we
would extend -Sp to include AUR packages but for now don't bother.
As it turns out, the times you need root also tend to be the time you
need to manipulate the database. So the needWait() function can be
removed and repllaced by needRoot()
