I am getting a small problem when using  `(cmd-cnum (read-number "context: "))`



Wrong type argument: sequencep, 8

Fair enough.

“read-from-minibuffer” as well as the functions suggested by Stefan
Monnier (“read-number”, “read-string”, …) have a parameter DEFAULT or
DEFAULT-VALUE (or similar) that you may use for that purpose; read their
documentation.

You may also check the return value of “read-from-minibuffer” or
“read-string” and act accordingly:

(let ((read-result (read-from-minibuffer "Prompt: ")))
(if (seq-empty-p read-result)
(setq read-result "default-value")))
