Subject: bug#28844: 26.0.90; display-line-numbers-mode should call window-configuration-change-hook
Date: Sun, 15 Oct 2017 17:56:43 +1000 [thread overview]
Message-ID: <1508054203.3504379.1139170720.0D0E99E9@webmail.messagingengine.com> (raw)
Activating/deactivating display-line-numbers-mode alters the window configuration and so should call window-configuration-change-hook but does not.
From the Emacs NEWS file:
> Lisp programs that need to know how much screen estate is used up for
> line-number display in a window can use the new function
> 'line-number-display-width'.
This is nice, but in order to use this, we need to know when to act upon it, e.g. when display-line-numbers-mode affects the window configuration. Or, if there is a more appropriate hook.
To reproduce:
1. emacs -Q
2. add a hook to window-configuration-change-hook
3. M-x display-line-numbers-mode
Expected results:
Hook added should run when enabling display-line-numbers.
Actual results:
Hook is not run.
Configuration:
GNU Emacs 26.0.90 (build 1, x86_64-apple-darwin17.0.0) of 2017-10-15
macOS 10.13 (17A405)
MacBook Pro (Retina, 15-inch, Mid 2015)
2.2 GHz Intel Core i7
16 GB 1600 MHz DDR3
Intel Iris Pro 1536 MB
