;;; Commentary:
;;
;; This file contains some functions which I use to improve the presentation
;; of buffers displayed in Aside windows.


;;; Code:

(defun aside-hook-enable-truncate-lines ()
  "Enables line truncation, without displaying a message about it."
  (let ((inhibit-message t))
    (toggle-truncate-lines 1)))

(defun aside-hook-disable-display-line-numbers-mode ()
  "Call command ‘display-line-numbers-mode’ to disable line numbers."
  (when (fboundp 'display-line-numbers-mode)
    (display-line-numbers-mode -1)))

(defun aside-hook-change-default-face-pitch ()
  "Make the default face inherit from ‘variable-pitch’."
  (face-remap-add-relative 'default :inherit 'variable-pitch))

(defun aside-hook-change-default-face-height ()
  "Change the height of the default face in the current buffer."
  (face-remap-add-relative 'default :height aside-default-face-height))

(defgroup aside ()
  "Options for Aside side windows.")

(defcustom aside-default-face-height 120
  "The default face height to use in buffers in a side window.
Used in ‘aside-hook-change-default-face-height’."
  :group 'aside
  :type 'integer)

(provide 'aside-hook-functions)
