1 aggressive-indent-mode [](http://melpa.org/#/aggressive-indent) [](http://stable.melpa.org/#/aggressive-indent) 2 ====================== 3 4 `electric-indent-mode` is enough to keep your code nicely aligned when 5 all you do is type. However, once you start shifting blocks around, 6 transposing lines, or slurping and barfing sexps, indentation is bound 7 to go wrong. 8 9 **`aggressive-indent-mode`** is a minor mode that keeps your code **always** 10 indented. It reindents after every change, making it more reliable 11 than `electric-indent-mode`. 12 13 ### Demonstration ### 14 15 - An example of Lisp mode (Emacs Lisp): 16  17 18 - An example of non-Lisp mode (C): 19  20 21 ### Instructions ### 22 23 This package is available from Melpa, you may install it by calling 24 25 M-x package-install RET aggressive-indent 26 27 Then activate it with 28 29 (add-hook 'emacs-lisp-mode-hook #'aggressive-indent-mode) 30 (add-hook 'css-mode-hook #'aggressive-indent-mode) 31 32 You can use this hook on any mode you want, `aggressive-indent` is not 33 exclusive to emacs-lisp code. In fact, if you want to turn it on for 34 every programming mode, you can do something like: 35 36 (global-aggressive-indent-mode 1) 37 (add-to-list 'aggressive-indent-excluded-modes 'html-mode) 38 39 #### Manual Installation #### 40 41 If you don't want to install from Melpa, you can download it manually, 42 place it in your `load-path` along with its dependency `cl-lib` (which 43 you should already have if your `emacs-version` is at least 24.3). 44 45 Then require it with: 46 47 (require 'aggressive-indent) 48 49 ### Customization ### 50 51 The variable `aggressive-indent-dont-indent-if` lets you customize 52 when you **don't** want indentation to happen. 53 For instance, if you think it's annoying that lines jump around in 54 `c++-mode` because you haven't typed the `;` yet, you could add the 55 following clause: 56 57 (add-to-list 58 'aggressive-indent-dont-indent-if 59 '(and (derived-mode-p 'c++-mode) 60 (null (string-match "\\([;{}]\\|\\b\\(if\\|for\\|while\\)\\b\\)" 61 (thing-at-point 'line))))) 62 63 ## Contribute ## 64 65 [](https://gratipay.com/Malabarba)
