;;; +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
|

|
||

;; 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.
