I’m currently in the process of writing functions to interact with
Systemd directly through StumpWM. For now, not much work is done, but
it’s a start.
First of all, I have the following function that lists all the system
or user services.
#+begin_src lisp
(defun systemd-get-services (&key user-p)
"Collect all systemd services running.
If USER-P is t, collect user services, otherwise collect system
services.
The value returned is a list of lists. The first element is the
service’s name, the second is its load state, the third the high-level
activation state of the service, and the fourth its low-level
activation state."
(mapcar (lambda (elt)
(multiple-value-bind (_ result)
(ppcre:scan-to-strings "(.*\\.service) *([^ ]+) *([^ ]+) *([^ ]+).*"
elt)
result))
(ppcre:split
" *\\n●? *"
(ppcre:regex-replace
"^ *"
(run-shell-command (concat "systemctl list-units --type service --all -q"
(if user-p " --user" ""))
t)
""))))
#+end_src
The only command I have right now is for listing the system or user
services with ~message~. Unfortunately, if there are too many services,
the list will overflow the screen. I do not know how to fix that yet.
I set the timeout to 600 seconds in order to have all the time in the
world to read the services list. It goes away as soon as something
else appears, such as a ~s-SPC C-g~ since I have ~which-key-mode~ enabled.
#+begin_src lisp
(defcommand systemd-list-services (user-p) ((:y-or-n "User services? "))
(let ((stumpwm::*timeout-wait* 600))
(message (format nil "~{~a~^~&~}"
(mapcar (lambda (service)
(let ((name (aref service 0))
(load (aref service 1))
