#+STARTUP: overview
#+TITLE: My Emacs
#+CREATOR: Laurens Miers

[[./img/dash_logo.png]]
* Installation
My personal emacs configuration
(Heavily) Inspired by the following configs:
- https://github.com/tuhdo/emacs-c-ide-demo
- https://github.com/daedreth/UncleDavesEmacs
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.
#+BEGIN_SRC emacs-lisp
(defun found-custom-arg (switch)
(let ((found-switch (member switch command-line-args)))
(setq command-line-args (delete switch command-line-args))
found-switch))
#+END_SRC
** 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.
#+BEGIN_SRC emacs-lisp
(setq EXWM_ENABLE nil)
(if (found-custom-arg "-start_wm")
(setq EXWM_ENABLE t)
)
#+END_SRC
* 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/
#+BEGIN_SRC emacs-lisp
(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)
#+END_SRC
* 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...
#+BEGIN_SRC emacs-lisp
(global-set-key (kbd "M-p") 'fill-paragraph)
#+END_SRC
** Macro's
Rebind the macro keys to Fx keys to give them a decent purpose.
#+BEGIN_SRC emacs-lisp
(global-set-key [f9] 'start-kbd-macro)
(global-set-key [f10] 'end-kbd-macro)
(global-set-key [f11] 'call-last-kbd-macro)
#+END_SRC
** Goto-line
Starting with Emacs 23.2, =M-g g= is bound to goto-line.
However, I find this too long. So rebind it:
#+BEGIN_SRC emacs-lisp
(global-set-key (kbd "M-g") 'goto-line)
#+END_SRC
** 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.
#+BEGIN_SRC emacs-lisp
(global-set-key (kbd "C-x r i") 'string-insert-rectangle)
(global-set-key (kbd "C-x r r") 'query-replace-regexp)
#+END_SRC
** 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/]])
#+BEGIN_SRC emacs-lisp
(setq gc-cons-threshold 100000000)
#+END_SRC
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:
#+BEGIN_SRC emacs-lisp
(defalias 'yes-or-no-p 'y-or-n-p)
#+END_SRC
** Emacs fullscreen at startup
#+BEGIN_SRC emacs-lisp
(add-to-list 'default-frame-alist '(fullscreen . maximized))
#+END_SRC
** Enable disabled commands
Some commands are disabled to protect the user.
Narrow-region/page is a really handy feature, enable it:
#+BEGIN_SRC emacs-lisp
(put 'narrow-to-page 'disabled nil)
(put 'narrow-to-region 'disabled nil)
#+END_SRC
** Buffers
Why is this not built-in?
#+BEGIN_SRC emacs-lisp
(defun kill-all-buffers ()
"Kill all buffers without regard for their origin."
(interactive)
(mapc 'kill-buffer (buffer-list)))
#+END_SRC
** Helping vim-users
#+BEGIN_SRC emacs-lisp
(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.")
#+END_SRC
** Backup files
Disable the generation of backup-files, I don't use them.
#+BEGIN_SRC emacs-lisp
(setq make-backup-files nil)
#+END_SRC
** 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.
#+BEGIN_SRC emacs-lisp
(defun move-to-help-window ()
(switch-to-buffer-other-window "*Help*")
)
(add-hook 'help-mode-hook 'move-to-help-window)
#+END_SRC
* Which-key
Display available keybindings in popup:
https://github.com/justbur/emacs-which-key
#+BEGIN_SRC emacs-lisp
(use-package which-key
:ensure t
:config
(which-key-setup-side-window-bottom)
(which-key-mode))
#+END_SRC
* Theme
#+BEGIN_SRC emacs-lisp
(use-package monokai-theme
:ensure t
:init
(load-theme 'monokai t)
)
#+END_SRC
** Highlight line
Highlight line will highlight the current line we are on.
Enable highlight-line globally and replace its background colour.
#+BEGIN_SRC emacs-lisp
(global-hl-line-mode 1)
(set-face-background hl-line-face "dark slate grey")
#+END_SRC
* 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=.
#+BEGIN_SRC emacs-lisp
(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 "")
)
#+END_SRC
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...
#+BEGIN_SRC emacs-lisp

(setq display-time-default-load-average nil)
(display-time-mode 1)
#+END_SRC
* 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.
#+BEGIN_SRC emacs-lisp
(setq kill-ring-max 5000) ; increase kill-ring capacity
(setq kill-whole-line t)
#+END_SRC
** Newline at end-of-file

#+BEGIN_SRC emacs-lisp

#+END_SRC
** Tab-width
Set the default tab width.
#+BEGIN_SRC emacs-lisp

Automatically indent when pressing =RET=.
#+BEGIN_SRC emacs-lisp
(global-set-key (kbd "RET") 'newline-and-indent)
#+END_SRC

Automatically delete trailing whitespace when saving a file.
#+BEGIN_SRC emacs-lisp

#+END_SRC
** Angry faces

#+BEGIN_SRC emacs-lisp

(setq c-basic-offset 4)
#+END_SRC
** Tabs vs spaces
Tabs are evil.
#+BEGIN_SRC emacs-lisp

#+END_SRC

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.
