Hi all,
Based on the docs, the three following forms should yield the same results:
(format-mode-line `(:propertize #("AB" 1 2 (x 0)) y 0))
(format-mode-line `(:propertize ("A" #("B" 0 1 (x 0))) y 0))
(format-mode-line '(:propertize ("A" (:propertize "B" x 0)) y 0))
But they don't:
(format-mode-line `(:propertize #("AB" 1 2 (x 0)) y 0))
=> #("AB" 0 2 (y 0)) ;; x 0 is dropped
(format-mode-line '(:propertize ("A" (:propertize "B" x 0)) y 0))
⇒ #("AB" 0 1 (y 0) 1 2 (x 0)) ;; y 0 is dropped on 1..2
(format-mode-line `(:propertize ("A" #("B" 0 1 (x 0))) y 0))
⇒ #("AB" 0 1 (y 0) 1 2 (y 0 x 0)) ;; Seems right
Am I misreading the docs?
Clément.
