    Edit

    +In this section I define some useful packages for editing. First of all, one of +the coolest packages out there is undo-tree. It allows you to navigate through +the undo history in a tree (because GNU Emacs is cool and keeps track of undo +actions in a tree structure instead of in a stack). This package is included in +recent versions of GNU Emacs. +

    + +
    + +
    (with-eval-after-load 'undo-tree
+  (global-undo-tree-mode 1)
+
+  (setq undo-tree-visualizer-diff t
+        undo-tree-visualizer-timestamps t
+        undo-tree-visualizer-relative-timestamps t)
+
+  (diminish 'undo-tree-mode)
+
+  (with-eval-after-load 'evil-leader
+    (evil-leader/set-key
+      "u" 'undo-tree-visualize)))
+
    +
    + +

    +Another important package is flycheck, which is an on-the-fly syntax checking +extension. This works with lots of languages with proper glue code. +

    + +
    + +
    (use-package let-alist
+  :ensure t)
+
+(use-package flycheck
+  :ensure t
+  :diminish
+  :config
+  (add-hook 'after-init-hook 'global-flycheck-mode)
+
+  ;; Only show the errors buffer if it isn't there and if I'm saving the
+  ;; buffer.
+  (setq flycheck-emacs-lisp-load-path 'inherit)
+  (setq flycheck-check-syntax-automatically '(mode-enabled save))
+  (setq flycheck-display-errors-function
+    #'flycheck-display-error-messages-unless-error-list))
+
    +
    + +

    +A recurring issue in speeches and presentations is that when showing something +with your editor, you have to increase/decrease the fonts. I use the +default-text-scale package for this. +

    + +
    + +
    (use-package default-text-scale
+  :ensure t
+  :config
+  (global-set-key (kbd "C-+") 'default-text-scale-increase)
+  (global-set-key (kbd "C--") 'default-text-scale-decrease))
+
    +
    + +

    +Some languages use some delimiters a lot (e.g. lisp languages and +parenthesis). For this reason I'm using the rainbow-delimiters package, which +properly highlights each level in a different way (provided that your theme +supports it). +

    + +
    + +
    (use-package rainbow-delimiters
+  :ensure t)
+
    +
    + +

    +I never use the mouse. +

    + +
    + +
    (use-package disable-mouse
+  :ensure t
+  :config
+  (global-disable-mouse-mode)
+  (setq global-disable-mouse-mode-lighter ""))
+
    +
    + +

    +Sometimes you begin typing a prefix, but then you forget the following +chord. For this reason which-key was created. It will show the available +commands for the current chord as a list. +

    + +
    + +
    (use-package which-key
+  :ensure t)
+
    +
    + +

    +For some modes it is important to count the number of words in the text. For +this, we have wc-mode. +

    + +
    + +
    (use-package wc-mode
+  :ensure t)
+
    +
    + +

    +Next on the list, we have writeroom-mode. I honestly don't use this package +that often, but it's cool to have a distraction-free screen from time to time. +

    + +
    + +
    (use-package writeroom-mode
+  :ensure t)
+
    +
    + +

    +The expand-region package is an extension that is based on a Vim one, which +expands the region of selection with a single key chord. Even if evil covers +most of my uses, it's convenient to have this tool anyways. +

    + +
    + +
    (use-package expand-region
+  :ensure t
+  :config
+
+  ; Set C-e as the expand command (mnemonic: expand). This command will
+  ; supercede the evil binding for "move one line", which I never use anyways.
+  (global-set-key (kbd "\C-e") 'er/expand-region)
+  (with-eval-after-load 'evil
+    (define-key evil-normal-state-map (kbd "\C-e") 'er/expand-region)
+    (define-key evil-visual-state-map (kbd "\C-e") 'er/expand-region)))
+
+(defun er/add-text-mode-expansions ()
+  "This way we can also expand the region into paragraphs & pages in text mode.
+Directly taken from: https://github.com/magnars/expand-region.el."
+
+  (set (make-local-variable 'er/try-expand-list) (append
+                                                  er/try-expand-list
+                                                  '(mark-paragraph
+                                                    mark-page))))
+
+(add-hook 'text-mode-hook 'er/add-text-mode-expansions)
+
    +
    + +

    +Editing files as root is a bit of a pain because usually the root user doesn't +have the same configuration as the current one, and attempting to do so can be +messy. So, instead of that, we could advice the find-file function so if the +file is not writable by the current user, then GNU Emacs will ask for editing +this same file as root: +

    + +
    + +
    (defadvice find-file (after find-file-sudo activate)
+  "Find file as root if necessary."
+  (if (and buffer-file-name
+           (not (file-writable-p buffer-file-name)))
+    (if (yes-or-no-p "Do you want to edit this file as root?")
+        (find-alternate-file (concat "/sudo:root@localhost:" buffer-file-name)))))
+
    +
    + +

    +YASnippet allows people to define shortcuts for writing some common blocks. +Moreover, it comes with a set of builtin snippets already. Since I don't +remember some of these snippets, I've mapped , h to +yas-describe-tables, which shows the available snippets in another buffer. +

    + +
    + +
    (use-package yasnippet
+  :ensure t
+  :diminish yas-minor-mode
+  :init (yas-global-mode)
+  :config
+  (yas-global-mode 1)
+  (with-eval-after-load 'evil-leader
+    (evil-leader/set-key "h" 'yas-describe-tables)))
