;;
;;; Commentary:

;; This file contains the code for managing your passwords with
;; Org-mode. It is part of org/contrib (see https://orgmode.org/). If
;; you want to contribute with development, or have a problem, do it
;; here: https://bitbucket.org/alfaromurillo/org-passwords.el

;; A basic setup needs to indicate a passwords file, and a dictionary
;; for the random words:

;;   (require 'org-passwords)
;;   (setq org-passwords-file "~/documents/passwords.gpg")
;;   (setq org-passwords-random-words-dictionary "/etc/dictionaries-common/words")

;; Basic usage:

;;   `M-x org-passwords' opens the passwords file in
;;   `org-passwords-mode'.

;;   `M-x org-passwords-generate-password' generates a random string
;;   of numbers, lowercase letters and uppercase letters.

;;   `C-u M-x org-passwords-generate-password' generates a random
;;   string of numbers, lowercase letters, uppercase letters and
;;   symbols.

;;   `M-x org-passwords-random-words' concatenates random words from
;;   the dictionary defined by `org-passwords-random-words-dictionary'
;;   into a string, each word separated by the string defined in
;;   `org-passwords-random-words-separator'.

;;   `C-u M-x org-passwords-random-words' does the same as above, and
;;   also makes substitutions according to
;;   `org-passwords-random-words-substitutions'.

;; It is also useful to set up keybindings for the functions
;; `org-passwords-copy-username', `org-passwords-copy-password' and
;; `org-passwords-open-url' in the `org-passwords-mode', to easily
;; make the passwords and usernames available to the facility for
;; pasting text of the window system (clipboard on X and MS-Windows,
;; pasteboard on Nextstep/Mac OS, etc.), without inserting them in the
;; kill-ring. You can set for example:

;;   (eval-after-load "org-passwords"
;;     '(progn
;;        (define-key org-passwords-mode-map
;; 	 (kbd "C-c u")
;; 	 'org-passwords-copy-username)
;;        (define-key org-passwords-mode-map
;; 	 (kbd "C-c p")
;; 	 'org-passwords-copy-password)
;; 	 (kbd "C-c o")
;; 	 'org-passwords-open-url)))

;; Finally, to enter new passwords, you can use `org-capture' and a
;; minimal template like:

;;   ("p" "password" entry (file "~/documents/passwords.gpg")
;;    "* %^{Title}\n  %^{URL}p %^{USERNAME}p %^{PASSWORD}p")

;; When asked for the password you can then call either
;; `org-passwords-generate-password' or `org-passwords-random-words'.
;; Be sure to enable recursive minibuffers to call those functions
;; from the minibuffer:

;;   (setq enable-recursive-minibuffers t)
