#+TITLE: Tom-Emacs Interface #+STARTUP: showall This is my personal Emacs configuration. The name was inspired by "Ghost in the Shell 2: Man-Machine Interface and Ryan Rix's "Complete Computing Environment". To start off, first I need to enable lexical binding. #+BEGIN_SRC emacs-lisp :padline no ;; -*- lexical-binding: t; -*- #+END_SRC * Package configuration Require package.el since I immediately start using its variables and functions anyway, no need to delay loading. #+BEGIN_SRC emacs-lisp (require 'package) #+END_SRC Add the MELPA and org package archives because I like living on the bleeding edge. This should be done both at run-time and compile-time so I can install packages at compile time. #+BEGIN_SRC emacs-lisp (eval-and-compile (add-to-list 'package-archives '("melpa" . "https://melpa.org/packages/")) (add-to-list 'package-archives '("org" . "http://orgmode.org/elpa/"))) #+END_SRC Add the directory with my mode-specific configuration files to the load path. #+BEGIN_SRC emacs-lisp (add-to-list 'load-path (locate-user-emacs-file "init/")) #+END_SRC Add all my vendored packages to the load path. #+BEGIN_SRC emacs-lisp (eval-and-compile (mapc (lambda (d) (add-to-list 'load-path d)) (directory-files (locate-user-emacs-file "vendor-lisp/") t "^[^.]"))) #+END_SRC Initialize package.el so that packages can be loaded and used. This also needs to be done at both run-time and compile-time so packages can be installed at compile-time. #+BEGIN_SRC emacs-lisp (eval-and-compile (package-initialize)) #+END_SRC Some actions produce a lot of output that is usually uninteresting during compilation. However, this information may be crucial when an error occurs. So for these actions I can use this macro, which stores all sent messages in a temporary buffer and prints them when an error occurs, and hides them when it doesn't. #+BEGIN_SRC emacs-lisp (defmacro silently (title &rest body) "Only output something when an error occurs. Prefix with TITLE any output that occurs while executing BODY, but only when an error occurs, otherwise discard it." (declare (indent 1)) (let ((buffer-var (cl-gensym)) (error-var (cl-gensym))) `(with-temp-buffer (let ((,buffer-var (current-buffer))) (cl-letf (((symbol-function 'message) (lambda (msg &rest args) (with-current-buffer ,buffer-var (insert " " (apply 'format msg args) "\n"))))) (condition-case ,error-var (progn ,@body) (error (princ ,(concat title " output:\n")) (princ (with-current-buffer ,buffer-var (buffer-string))) (princ "Error:\n") (princ " ") (princ (cadr ,error-var)) (princ "\n")))))))) #+END_SRC Refresh the package contents so packages can be installed from all configured archives. Don't do this at run-time because it slows down the process too much. #+BEGIN_SRC emacs-lisp (eval-when-compile (let* ((not-installed (seq-remove 'package-installed-p package-selected-packages)) (available (seq-filter (lambda (p) (assq p package-archive-contents)) not-installed)) (difference (- (length not-installed) (length available)))) (when (> difference 0) (silently "Refresh packages" (package-refresh-contents))) (when available (mapc (lambda (p) (package-install p t)) available)))) #+END_SRC * Site lisp Setup everything so that any autoloads in ~site-lisp/~ get loaded and can be used. #+BEGIN_SRC emacs-lisp (eval-and-compile (add-to-list 'load-path (locate-user-emacs-file "site-lisp/")) (let ((loaddefs (locate-user-emacs-file "site-lisp/site-autoloads.el"))) (when (file-exists-p loaddefs) (load loaddefs)))) #+END_SRC * Helper functions I have some helper functions stored away in a separate file. #+BEGIN_SRC emacs-lisp (require 'oni-helpers) #+END_SRC * Backups I don't like having every directory filled with "filename~" files. So instead of saving backup files to the same directory, save them to a special one instead. #+BEGIN_SRC emacs-lisp (setq backup-directory-alist `((".*" . ,(oni:data-location "backup-files/")))) #+END_SRC * Auto saves I prefer to keep all autosave files in a single directory so they don't clog up my filesystem so much. Usually these files get deleted, but sometimes they don't, and I don't think they look pretty. Add it to the end of the list because the default value stores auto-saves for remote files in /tmp, which is fine by me. #+BEGIN_SRC emacs-lisp (add-to-list 'auto-save-file-name-transforms `(".*" ,(oni:data-location "auto-save-files/") t) :append) #+END_SRC Place the files which contain the auto save files in a similar directory. #+BEGIN_SRC emacs-lisp (setq auto-save-list-file-prefix (oni:data-location "auto-save-list/.saves-")) #+END_SRC * Tabs Generally I prefer using spaces over tabs. Especially for lisp-like languages. #+BEGIN_SRC emacs-lisp (setq-default indent-tabs-mode nil) #+END_SRC A tab-width of 8 is too wide for me, and 2 is too narrow. 4 is just right. #+BEGIN_SRC emacs-lisp (setq-default tab-width 4) #+END_SRC * Inhibit startup screen I've been using Emacs long enough not to need the startup screen anymore. I don't see it on my PC where I start Emacs in daemon mode, but on my laptop I always start it normally, so it gets in the way. #+BEGIN_SRC emacs-lisp (setq inhibit-startup-screen t) #+END_SRC * Font Set the default font to a more pleasing one, in my opinion, with a better size as well. #+BEGIN_SRC emacs-lisp (add-to-list 'default-frame-alist '(font . "Fantasque Sans Mono-15")) #+END_SRC * Internal border For aesthetics I like to have a thick border on the inside of my Emacs window. I have the same border in URxvt, but I haven't found out how to add it to Conkeror yet. #+BEGIN_SRC emacs-lisp (add-to-list 'default-frame-alist '(internal-border-width . 15)) #+END_SRC * Menu bar I don't use the menu bar, so it just takes up space. #+BEGIN_SRC emacs-lisp (menu-bar-mode -1) #+END_SRC * Tool bar I don't use the tool bar, so it just takes up space. #+BEGIN_SRC emacs-lisp (tool-bar-mode -1) #+END_SRC * Scroll bar I don't use the scroll bar to either navigate my buffers or see whereabouts I am, so they just take up space. #+BEGIN_SRC emacs-lisp (scroll-bar-mode -1) #+END_SRC * Cursor Use a bar cursor instead of a box. #+BEGIN_SRC emacs-lisp (setq-default cursor-type '(bar . 2)) #+END_SRC * Whitespace I hate it when trailing whitespace is left around a file. I've been using this for years, and apart from having some trouble working with people who don't pay attention to it, it has worked flawlessly. #+BEGIN_SRC emacs-lisp (require 'destroy-trailing-whitespace) (global-destroy-trailing-whitespace-mode) #+END_SRC Having a final newline at the end of the file is always a good idea. Some programs just don't work without it and others produce some strange results. Github diffs are an example. #+BEGIN_SRC emacs-lisp (setq require-final-newline t) #+END_SRC * Long lines By default Emacs wraps long lines around to the next line when they reach the far end of the window. However I prefer to have them truncated instead. #+BEGIN_SRC emacs-lisp (setq-default truncate-lines t) #+END_SRC * Theme #+BEGIN_SRC emacs-lisp (add-to-list 'custom-theme-load-path (concat user-emacs-directory "vendor-lisp/yoshi-theme")) (load-theme 'yoshi :no-confirm) #+END_SRC * Diminish I really don't need to see some of the minor modes. #+BEGIN_SRC emacs-lisp (require 'diminish) #+END_SRC * Ivy Ivy is a completing read implementation that offers choises vertically. I'm surprised how much I like it. I've tried Swiper before and I didn't like that so much. Since I immediately use and enable Ivy, there's no need to autoload it, so require it to keep the byte-compiler quiet. #+BEGIN_SRC emacs-lisp (require 'ivy) #+END_SRC Don't show that ivy is enabled in the mode-line. It's enabled globally and I'll notice it from other things anyway (like it showing up). #+BEGIN_SRC emacs-lisp (diminish 'ivy-mode) #+END_SRC Enable fuzzy matching in Ivy. #+BEGIN_SRC emacs-lisp (setq ivy-re-builders-alist '((t . ivy--regex-fuzzy)) ivy-initial-inputs-alist nil) #+END_SRC Enable Ivy. #+BEGIN_SRC emacs-lisp (ivy-mode) #+END_SRC * Counsel Counsel is a group of functions that use Ivy to specialize on certain built-in commands, such as M-x. Since I enable Counsel mode immediately, there's no point in leaving it to be autoloaded. Requiring it keeps the byte-compiler happy. #+BEGIN_SRC emacs-lisp (require 'counsel) #+END_SRC Hide dotfiles in =counsel-find-file=. #+BEGIN_SRC emacs-lisp (setq counsel-find-file-ignore-regexp (rx (or (and bos ".") (and ".zwc" eos)))) #+END_SRC Enable Counsel. #+BEGIN_SRC emacs-lisp (counsel-mode) #+END_SRC Don't show that counsel is enabled in the mode-line. It's enabled globally and I'll notice whenever I press M-x for example. #+BEGIN_SRC emacs-lisp (diminish 'counsel-mode) #+END_SRC * Bookmarks Save bookmarks in my data directory so my =user-emacs-directory= is less cluttered. #+BEGIN_SRC emacs-lisp (eval-when-compile (require 'bookmark)) (setq bookmark-default-file (oni:data-location "bookmarks")) #+END_SRC * Personal info Set some personal info for, for example, Gnus to use. #+BEGIN_SRC emacs-lisp (setq user-full-name "Tom Willemse" user-mail-address "tom@ryuslash.org") #+END_SRC * Automatic alignment Emacs has some powerful automatic alignment features. #+BEGIN_SRC emacs-lisp (eval-when-compile (require 'align)) #+END_SRC ** CSS Align CSS files like so: #+BEGIN_SRC css body { color: #ffffff; } .some-class { background-color: #ffffff; } #some-id { width: 200px; } .some-more-class { color: #ffffff; background-color: #ffffff; width: 200px; } #+END_SRC #+BEGIN_SRC emacs-lisp (with-eval-after-load 'align ;; Keep these in order.

It can feel rather strict and uncomfortable at first, but once you get the hang of using it, you won't want to live without it. Don't show that paredit is enabled, it should be obvious from the effects it has.

I prefer the original situation because my muscle-memory still remembers to use C-j for newline-and-indent behaviour. #+BEGIN_SRC emacs-lisp (defun oni:switch-newline-keys () "Switch the C-j and RET keys in the local buffer."
