What does the -> mean here:

(interactive 
  (list 
    (-> (dap--completing-read "Select configuration template: "
          (-mapcat #'funcall dap-launch-configuration-providers)
          'cl-first nil t))))

It's the name of a Lisp macro provided by library dash.el. Checkout C-h f.

    Could you please elaborate by providing what `C-h f` shows for `->`? Thx. Bonus points for explaining what it does in the question's example. – Drew Nov 17 '20 at 04:54
