zsh has a completion system, activated by pressing tab:
llama@llama:~$ git st<Tab> Completing main porcelain command stash -- stash away changes to dirty working directory status -- show working-tree status Completing plumbing internal helper command stripspace -- filter out empty lines
All I've been able to figure out is that this comes from the script
_git is the completion command being called.
Assuming I know the name of the completion function (e.g.
_git), how could I get the output of what would happen if I entered a certain string and pressed tab? Essentially, I'm trying to take an input of ex.
git st and get the output above (programmatically, from a script).
