zsh has a completion system, activated by pressing tab:llama@llama:~$ git st<Tab>Completing main porcelain commandstash      -- stash away changes to dirty working directorystatus     -- show working-tree statusCompleting plumbing internal helper commandstripspace -- filter out empty linesAll I've been able to figure out is that this comes from the script /usr/share/zsh/functions/Completion/Unix/_git, where _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).There are many other existing questions about this for bash, but I haven't found anything explaining how to achieve this with zsh.
How can I programmatically access zsh completion?
