;;; +finger.el --- Finger bugfix -*- lexical-binding: t; -*-
;;; Commentary:
;; `net-utils' defines `finger', which purportedly consults
;; `finger-X.500-host-regexps' to determine what hosts to only send a username
;; to. I've found that that is not the case, and so I've patched it. At some
;; point I'll submit this to Emacs itself.
;;; Code:
(require 'net-utils) ; this requires everything else I'll need.
(require 'seq)
(defun finger (user host)
"Finger USER on HOST.
This command uses `finger-X.500-host-regexps'
and `network-connection-service-alist', which see."
;; One of those great interactive statements that's actually
;; longer than the function call! The idea is that if the user
;; uses a string like "pbreton@cs.umb.edu", we won't ask for the
;; host name. If we don't see an "@", we'll prompt for the host.

(let* ((answer (read-from-minibuffer "Finger User: "
(net-utils-url-at-point)))

(list (substring answer 0 index)
