;;^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
;;Common (group based on `GNU Emacs Manual')
;;^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
;;======================================
;;{{-- Important General Concepts
;;[[--Entering Emacs
;;You can also force Emacs to display a file or directory at startup by setting the variable `initial-buffer-choice' to a non-`nil' value.(In that case, even if you specify one or more files on the command line, Emacs opens but does not display them.)
;(setq initial-buffer-choice t)      ;;The value of `initial-buffer-choice' can be either the name of the desired file or directory, or `t', which means to display the `*scratch*' buffer.
(setq inhibit-startup-screen t)	    ;;If the variable `inhibit-startup-screen' is non-`nil', Emacs does not display the startup screen.

;;[[-- Exiting Emacs
;;If the value of the variable `confirm-kill-emacs' is non-`nil', `C-x C-c' assumes that its value is a predicate function, and calls that function.  If the result of the function call is non-`nil', the session is killed, otherwise Emacs continues to run.
(setq confirm-kill-emacs 'yes-or-no-p)

;;======================================
;;{{-- Fundamental Editing Commands
;;[[-- Basic
;;--Inserting Text
;;To insert a non-graphic character, or a character that your keyboard does not support, first "quote" it by typing `C-q' (`quoted-insert').
;;`C-q' followed by any non-graphic character (even `C-g') inserts that character.  For instance, `C-q <DEL>' inserts a literal `DEL' character.
;;`C-q' followed by a sequence of octal digits inserts the character with the specified octal character code.
(setq read-quoted-char-radix 16)    ;;To use decimal or hexadecimal instead of octal, set the variable `read-quoted-char-radix' to 10 or 16.


;;[[-- Minibuffer
(setq resize-mini-windows t)        ;;A value of t means resize them to fit the text displayed in them.
(setq completion-auto-help 'lazy)   ;;Emacs only shows the completion list buffer on the second attempt to complete
(setq history-delete-duplicates t)  ;;adding a new element deletes from the list all other elements that are equal to i
(icomplete-mode t)                  ;;Icomplete mode presents a constantly-updated display that tells you what completions are available for the text you've entered so far
;;<<-- Minibuffer Edit
(setq enable-recursive-minibuffers t)

;;[[-- Help
;;((-- Misc Help
;;--InfoMode
;; C-u C-h i : open a file in info-mode
(defun fun-reopen-in-info-mode ()
  (let ((file-name (buffer-file-name)))
    (kill-buffer (current-buffer))
    (info file-name)
  )
)
(add-to-list 'auto-mode-alist '("\\.info\\'" . fun-reopen-in-info-mode))

;;((-- Help Echo
(setq help-at-pt-display-when-idle t)   ;;To display help text automatically whenever it is available on the character after point


;;======================================
;;{{-- Important Text-Changing Commands
;;[[-- Mark
(delete-selection-mode t)           ;;inserting text while the mark is active causes the selected text to be deleted first

;;[[-- Yanking
;;-- Yanking Earlier Kills
(setq kill-ring-max 200)            ;;The length of the kill ring is controlled by the variable `kill-ring-max'; no more than that many blocks of killed text are saved.

;;[[-- Display
;;--Horizontal Scrolling
(setq hscroll-margin 8)             ;;The variable `hscroll-margin' controls how close point can get to the window's edges before automatic scrolling occurs.

;;--Follow Mode                     ;;"Follow mode" is a minor mode that makes two windows, both showing the same buffer, scroll as a single tall "virtual window."
;(follow-mode t)

;;Highlight Interactively
;(global-highlight-changes-mode t)   ;;Highlight Changes mode is a minor mode that "highlights" the parts of the buffer were changed most recently, by giving that text a different face.
(global-hi-lock-mode t)             ;;Hi Lock mode is a minor mode that highlights text that matches regular expressions you specify.


;;--Displaying Boundaries
(setq default-indicate-buffer-boundaries '((top . left) (bottom . left) (t . nil)))

;;--Useless Whitespace
(setq-default show-trailing-whitespace t)   ;; You can make trailing whitespace at the end of a line visible by setting the buffer-local variable `show-trailing-whitespace' to `t'.

;;--Optional Mode Line
(size-indication-mode t)            ;;When Size Indication mode is enabled, the size of the accessible part of the buffer appears in the mode line
(column-number-mode t)              ;;When Column Number mode is enabled, the column number appears in the mode line
(setq line-number-mode t)           ;;When Line Number mode is enabled, the line number appears in the mode line.

;;--Text Display
;;--Tab
;(setq tab-width 4)                 ;;The number of spaces per tab is controlled by the variable `tab-width', and is made local by changing it
;(setq default-tab-width 4)         ;; controls the default value of `tab-width' for buffers where you have not set it locally.

;;--Cursor Display
(setq visible-cursor t)             ;;Some text terminals offer two different cursors: the normal cursor and the very visible cursor, where the latter may be e.g. bigger or blinking.
(global-hl-line-mode t)             ;;To make the cursor even more visible, you can use HL Line mode, a minor mode that highlights the line containing point.

;;--Line Truncation
;;You can explicitly enable line truncation for a particular buffer with the command `M-x toggle-truncate-lines'.
;(setq-default truncate-lines t)     ;;If variable `truncate-lines' is non-`nil', long lines are truncated; if it is `nil', they are continued onto multiple screen lines.

;;[[-- Search
(setq default-case-fold-search nil) ;;If you set the variable `case-fold-search' to `nil', then all letters must match exactly, including case


;;======================================

;;[[-- Files

(setq backup-directory-alist '(
  ("." . "~/.backup/emacs/")

;;--Automatic Deletion of Backups
;;The two variables `kept-old-versions' and `kept-new-versions' control this deletion.  Their values are, respectively, the number of oldest (lowest-numbered) backups to keep and the number of newest (highest-numbered) ones to keep, each time a new backup is made.  The backups in the middle (excluding those oldest and newest) are the excess middle versions--those backups are deleted.  These variables' values are used when it is time to delete excess versions, just after a new backup version is made; the newly made backup is included in the count in `kept-new-versions'.  By default, both variables are 2.
;;If `delete-old-versions' is `t', Emacs deletes the excess backup files silently.  If it is `nil', the default, Emacs asks you whether it should delete the excess backup versions.
(setq kept-old-versions 2)
