;;; 99-misc.el --- My miscellaneous functions. -*- no-byte-compile: t; lexical-binding: t; -*-

;;; Description:
;; This file contains my miscellaneous functions and their key binding code.
;; Some of those functions were written by me, some of them are taken from the
;; internet.

;;; Code:

(defun my/resize-margins-to-fill ()
  "Set the current buffer margins so that its width is equal to the fill
column."
  (interactive)
  (let ((margin-size (/ (- (frame-width) fill-column) 2)))
    (set-window-margins nil margin-size margin-size)))

(defun my/reset-margins ()
  "Removes margins from the current buffer."
  (interactive)
  (set-window-margins nil nil nil))

(defun my/insert-buffer-name ()
  "Inserts the name of the current buffer at point."
  (interactive)
  (let ((name (buffer-name)))
    (insert name)))

(setq margins-map (make-sparse-keymap))
(keymap-set margins-map "f" 'my/resize-margins-to-fill)
(keymap-set margins-map "r" 'my/reset-margins)

(keymap-set mode-specific-map "C-m" margins-map)
(keymap-set mode-specific-map "b" 'my/insert-buffer-name)
