Subject: bug#32640: 26.1; Make `kill-process' a command
Date: Wed, 5 Sep 2018 21:32:53 +1200 [thread overview]
Message-ID: <c1c3fc1e-2134-b819-142c-b2e23901745e@orcon.net.nz> (raw)
[-- Attachment #1: Type: text/plain, Size: 142 bytes --]
Not being able to use M-x kill-process (especially for killing
the current buffer's process) is something which has annoyed me
periodically.
[-- Attachment #2: kill-process-interactive.el --]

;; Make `kill-process' a command.
;; (put 'kill-process 'interactive-form '(interactive))
(put 'kill-process 'interactive-form
'(interactive (kill-process-read-arg)))
(defun kill-process-read-arg ()
"Obtain arguments interactively for `kill-process'."
;; Currently supports only the PROCESS argument.
;; Must either return a list containing a process, or signal an error.
;; (Returning `nil' would mean the current buffer's process.)
(unless (fboundp 'process-list)
(error "Asynchronous subprocesses are not supported on this system"))
;; Local function to return cons of a complete-able name, and the
;; associated process object, for use with `completing-read'.
(cl-flet ((procitem

(let ((pid (process-id p))
(procname (process-name p))
(procbuf (process-buffer p)))
(and (eq (process-type p) 'real)
(cons (if procbuf
(format "%s (%s) in buffer %s"
procname pid

(format "%s (%s)" procname pid))

;; Perform `completing-read' for a process.
