Installation

My personal emacs configuration

(Heavily) Inspired by the following configs:

This configuration requires the installation of :

  • the GNU global package (for gtags)
  • clang (for ivory)
  • cmake (for ivory)
  • llvm-libs (for cmake, somehow not a dependency on Manjaro when installing cmake)
  • Use python-pip to install requirements for elpy: pip install jedi flake8 importmagic autopep8 yapf
  • ditaa (for ascii to image generation in org-mode)

When first checking out this config, run irony-install-server to make and install the irony-server.

Utils

Custom command line arguments

Return if a custom command line arguments was found. If it was found, we delete it from the list of command line arguments.

(defun found-custom-arg (switch)
  (let ((found-switch (member switch command-line-args)))
    (setq command-line-args (delete switch command-line-args))
    found-switch))

Global variables

Some package behave strangely if we have custom command line parameters. F.e. Dashboard assumes you are directly opening a file so it won't load the dashboard.

So, we remove our custom variables from the command line arguments and set global 'flags'. These flags will enable/disable parts of the config.

(setq EXWM_ENABLE nil)

(if (found-custom-arg "-start_wm")
  (setq EXWM_ENABLE t)
)

Term

Toggle between char- and line-mode

Courtesy goes to https://joelmccracken.github.io/entries/switching-between-term-mode-and-line-mode-in-emacs-term/

(require 'term)

(defun jnm/term-toggle-mode ()
  "Toggles term between line mode and char mode"
  (interactive)
  (if (term-in-line-mode)
      (term-char-mode)
    (term-line-mode)))

(define-key term-mode-map (kbd "C-c C-j") 'jnm/term-toggle-mode)
(define-key term-mode-map (kbd "C-c C-k") 'jnm/term-toggle-mode)

(define-key term-raw-map (kbd "C-c C-j") 'jnm/term-toggle-mode)
(define-key term-raw-map (kbd "C-c C-k") 'jnm/term-toggle-mode)

Resize frame

Minor-mode to easily resize frames (works with EXWM (firefox, …)). Courtesy goes to kuanyui (https://gist.github.com/kuanyui/65a408d393871048771c):

General stuff

Unsorted

Collection of stuff that needs to be sorted…someday….maybe…

(global-set-key (kbd "M-p") 'fill-paragraph)

Macro's

Rebind the macro keys to Fx keys to give them a decent purpose.

(global-set-key [f9]  'start-kbd-macro)
(global-set-key [f10]  'end-kbd-macro)
(global-set-key [f11]  'call-last-kbd-macro)

Goto-line

Starting with Emacs 23.2, M-g g is bound to goto-line. However, I find this too long. So rebind it:

(global-set-key (kbd "M-g") 'goto-line)

Rectangle

Most rectangle functions are by default mapped to something like C-x r (other-char). I use string-insert-rectangle and query-replace-regexp quite a lot, so rebind it to something easy to remember.

(global-set-key (kbd "C-x r i") 'string-insert-rectangle)
(global-set-key (kbd "C-x r r") 'query-replace-regexp)

Garbage collection (gc)

I used to have the following enabled in my init to increase the gc threshold to speed-up emacs startup: (stolen from http://bling.github.io/blog/2016/01/18/why-are-you-changing-gc-cons-threshold/)

(setq gc-cons-threshold 100000000)

But according to this: https://lists.gnu.org/archive/html/help-gnu-emacs/2007-06/msg00243.html , it is no longer necessary. But I found that I still have to do this to speed up emacs.

Yes-or-no questions

Because I'm lazy, important yes-or-no questions can be answered with y-or-n:

(defalias 'yes-or-no-p 'y-or-n-p)

Emacs fullscreen at startup

(add-to-list 'default-frame-alist '(fullscreen . maximized))

Enable disabled commands

Some commands are disabled to protect the user. Narrow-region/page is a really handy feature, enable it:

(put 'narrow-to-page 'disabled nil)
(put 'narrow-to-region 'disabled nil)

Buffers

Why is this not built-in?

(defun kill-all-buffers ()
  "Kill all buffers without regard for their origin."
  (interactive)
  (mapc 'kill-buffer (buffer-list)))

Helping vim-users

(defconst wq "This is not vi!  Use C-x C-c instead.")
(defconst w "This is not vi!  Use C-x C-s instead.")
(defconst q! "This is EMACS not vi!  Use C-x C-c instead.")
(defconst wq! "This is EMACS not vi!  Use C-x C-c instead.")

Backup files

Disable the generation of backup-files, I don't use them.

(setq make-backup-files nil)

Describe key

Describe key will open a new buffer with the relevant information. However, it stays in the current window and opens a new window with the help-info, forcing you to switch buffers to close the help window. This small function just switches the focus to the newly opened window so we can close it more easily.

(defun move-to-help-window ()
  (switch-to-buffer-other-window "*Help*")
)
(add-hook 'help-mode-hook 'move-to-help-window)

Which-key

Display available keybindings in popup: https://github.com/justbur/emacs-which-key

(use-package which-key
  :ensure t
  :config
    (which-key-setup-side-window-bottom)
    (which-key-mode))

Theme

(use-package monokai-theme
  :ensure t
  :init
    (load-theme 'monokai t)

)

Highlight line

Highlight line will highlight the current line we are on. Enable highlight-line globally and replace its background colour.

(global-hl-line-mode 1)
(set-face-background hl-line-face "dark slate grey")

Dashboard

I use the dashboard as start screen. Since I like it to give me a list of recent files, we need to enable recentf-mode.

(use-package dashboard
  :ensure t
  :init
    (recentf-mode 1)
  :config
    (dashboard-setup-startup-hook)
    (setq dashboard-startup-banner "~/.emacs.d/img/dash_logo.png")
    (setq dashboard-items '((recents  . 10)
                            (bookmarks . 5)
                            ))
    (setq dashboard-banner-logo-title "")
)

Important to note, dashboard-setup-startup-hook will not display the dashboard when command-line arguments are provided. It assumes the command line arguments are filenames and skips showing the dashboard.

Zygospore

Revert C-x 1 by pressing C-x 1 again: https://github.com/louiskottmann/zygospore.el

FYI: At one point, used this together with sr-speedbar. They did not play well together…

(use-package zygospore
  :ensure t
  :config
    (global-set-key (kbd "C-x 1") 'zygospore-toggle-delete-other-windows)
)

Mode-line

Clock

  (setq display-time-24hr-format t)
  (setq display-time-format "%H:%M - %d %b %Y")
  (setq display-time-default-load-average nil)

  (display-time-mode 1)

Editing settings

Kill-ring customization

Setting kill-whole-line to non-nil means when we execute C-k at the beginning of a line will the entire line including the following newline will be deleted.

(setq kill-ring-max 5000) ; increase kill-ring capacity
(setq kill-whole-line t)

Newline at end-of-file

(setq mode-require-final-newline t) ; add a newline to end of file

Enable column numbers

(setq column-number-mode 1)

Look-and-feel modifications

Remove scroll-, tool- and menu-bar. I don't use them so free some space.

(scroll-bar-mode -1)
(tool-bar-mode -1)
(menu-bar-mode -1)

Tab-width

Set the default tab width.

(setq-default tab-width 4)

Automatic indent

Automatically indent when pressing RET.

(global-set-key (kbd "RET") 'newline-and-indent)

Delete trailing whitespace

Automatically delete trailing whitespace when saving a file.

(add-hook 'before-save-hook 'delete-trailing-whitespace)

Angry faces

;; make angry face to get my attention
(setq prog-modes '(c++-mode python-mode erlang-mode java-mode c-mode emacs-lisp-mode scheme-mode prog-mode))
(make-face 'font-lock-angry-face)
(modify-face 'font-lock-angry-face "Red" "Yellow" nil t nil t nil nil)

;; Add keywords to recognize to angry face
(mapc (lambda (mode)
		(font-lock-add-keywords

(mapc (lambda (mode)
		(font-lock-add-keywords
		 mode
		 '(("\\<\\(TODO\\)" 1 'font-lock-angry-face t)))
		)
	  prog-modes)

C Coding settings

Some basic C-coding settings (style, indentation offset, …).

;; default coding style
(setq c-default-style "linux")

;; sane indentation offset
(setq c-basic-offset 4)

Tabs vs spaces

Tabs are evil.

(setq-default indent-tabs-mode nil)

Undo-tree

Undo with C-/.

(use-package undo-tree
  :ensure t
  :config
    (global-undo-tree-mode)
)

Volatile highlights

Show/highlight changes when doing undo/yanks/kills/…

https://github.com/k-talo/volatile-highlights.el

(use-package volatile-highlights
  :ensure t

iedit

Highlight occurences of symbol and replace them simultanously. Shortkey: C-;

https://github.com/victorhge/iedit

(use-package smartparens
  :ensure t

    (require 'smartparens-config)
    (show-smartparens-global-mode t)
    (smartparens-global-mode t)

Expand-region

Expand region increases the selected region by semantic units. I also enable pending-delete-mode, this means when we mark a region and start typing, the text within the mark is deleted with the new typed text and the mark disappears.

https://github.com/magnars/expand-region.el

(use-package expand-region
   :ensure t

     (pending-delete-mode t)

Windooze

;; Windows performance tweaks

(when (boundp 'w32-pipe-read-delay)
  (setq w32-pipe-read-delay 0))
;; Set the buffer size to 64K on Windows (from the original 4K)
(when (boundp 'w32-pipe-buffer-size)
  (setq irony-server-w32-pipe-buffer-size (* 64 1024)))

;; Set pipe delay to 0 to reduce latency of irony
(setq w32-pipe-read-delay 0)

;; From "setting up irony mode on Windows" :
;; Make sure the path to clang.dll is in emacs' exec_path and shell PATH.
(setenv "PATH"
        (concat
         "C:\\msys64\\usr\\bin" ";"
         "C:\\msys64\\mingw64\\bin" ";"
         (getenv "PATH")
         )

Windows

Splitting

After you split a window, your focus remains in the previous one. Credit goes to https://github.com/daedreth/UncleDavesEmacs

(defun split-and-follow-horizontally ()
  (interactive)
  (split-window-below)
  (balance-windows)
  (other-window 1))
(global-set-key (kbd "C-x 2") 'split-and-follow-horizontally)

(defun split-and-follow-vertically ()
  (interactive)
  (split-window-right)
  (balance-windows)
  (other-window 1))
(global-set-key (kbd "C-x 3") 'split-and-follow-vertically)

Switching

https://github.com/dimitri/switch-window

Explanation for different config when EXWM is in the README on the github.

(use-package switch-window
  :ensure t
  :config
    (setq switch-window-input-style 'minibuffer)
    (setq switch-window-increase 6)
    (setq switch-window-threshold 2)
    (setq switch-window-shortcut-style 'qwerty)
    (setq switch-window-qwerty-shortcuts
        '("a" "s" "d" "f" "j" "k" "l" "i" "o"))
    (setq switch-window-multiple-frames t)

    (if EXWM_ENABLE
      (progn
        (setq switch-window-input-style 'minibuffer)
      )
    )




  :bind
    ("C-x o" . switch-window))

When using exwm, have a look at this: https://github.com/dimitri/switch-window/pull/62

Multi-frame rebindings (OBSOLETE with switch-window)

Sometimes I have multiple emacs-frames open. In the past, I preferred that the normal C-x o can deal with this but this is used by switch-window now.

;; ;; Use C-x o to switch to other frame when using multi-monitor
;; (global-set-key (kbd "C-x o") 'next-multiframe-window)

Now that next-multiframe-window is bound to C-x o, Bind C-x p to previous-multiframe-window.

;; (global-set-key (kbd "\C-x p") 'previous-multiframe-window)
