;;; 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)))

(defun my-create-org-fc-word-card ()
  "Inserts and initialzes an org-fc double card with a word and its
translation at point."
  (interactive)
  (let* ((engw (read-from-minibuffer "Enter English word: "))
         (rusw (read-from-minibuffer "Enter Russian word: ")))
    (insert "* " engw)
    (newline)
    (insert rusw)
    (previous-line)
