#+TITLE: Jose's Emacs Config
Setup property for all code-blocks to tangle by default
#+PROPERTY: header-args:emacs-lisp :tangle yes
* Init
** Package and sources and init
Add MELPA and the https version of elps to the package sources.
This should preferrably be done in the init-file, before this file is loaded to allow for byte-compiling.
#+BEGIN_SRC emacs-lisp :tangle no
(require 'package)
(setq-default package-archives
'(("gnu" . "https://elpa.gnu.org/packages/")
("melpa" . "https://melpa.org/packages/")))
(setq-default package-enable-at-startup nil)
(package-initialize)
#+END_SRC
** Set up use-package and install if missing
This should preferrably be done in the init-file, before this file is loaded to allow for byte-compiling.
#+BEGIN_SRC emacs-lisp :tangle no
(unless (package-installed-p 'use-package)
(progn
(package-refresh-contents)
(package-install 'use-package)))
(require 'use-package)
#+END_SRC
* Utils
** Evil
Because I'm a vimmer.
Install the evil package if it is not installed, and call it once it has loaded.
`evil-want-C-i-jump` to 'nil fixes an issue where evil breaks tabs in org-mode src code
Thank you to this article for the fix: https://jeffkreeftmeijer.com/emacs-evil-org-tab/
#+BEGIN_SRC emacs-lisp
(use-package evil
:ensure t
:init
;; set this to nil because it breaks tabs in org-mode
(setq evil-want-C-i-jump 'nil)
:config
(evil-mode))
#+END_SRC
** pdf-tools
for viewing PDFs in emacs
#+begin_src emacs-lisp
(use-package pdf-tools
:ensure t
:config
(pdf-tools-install))
(add-hook 'pdf-view-mode-hook
(lambda ()
;; Disable line numbers for pdfs
(display-line-numbers-mode -1)
;; Enable midnight mode (dark mode) by default
(pdf-view-midnight-minor-mode 1)))
#+end_src
* Modes
** markdown
Major mode for editing Markdown files
#+begin_src emacs-lisp
(use-package markdown-mode
:ensure)
#+end_src
** nov.el
Major mode for reading EPUBs
#+begin_src emacs-lisp
(use-package nov
:ensure)
#+end_src
* Fixes
** Org Source Code Auto-Indent
By default, src-blocks are auto-indented 2 spaces. This breaks certain languages, as org-mode will continuously add 2 spaces on enter inside of some expressions.
Setting indentation to 0 fixes the issue.
#+BEGIN_SRC emacs-lisp
(setq org-edit-src-content-indentation 0)
#+END_SRC
** Org Inline Images
By default, Org mode displays inline images according to their actual width. By changing this value to nil, org will try to get the width from an ‘#+ATTR.*’ keyword and fall back on the original width if none is found.
#+begin_src emacs-lisp
(setq org-image-actual-width 'nil)
#+end_src
By default, inline images are not displayed, and must be toggled on with *C-c C-x C-v (org-toggle-inline-images)*.
With this we ask for inline images to be displayed at startup.
#+begin_src emacs-lisp
(setq org-startup-with-inline-images t)
#+end_src
** Org Latex Preview
The org latex preview from within org files is too small by default.
#+begin_src emacs-lisp
(setq org-format-latex-options
(plist-put org-format-latex-options
:scale 2))
#+end_src
Org latex preview uses 'divpng by default, which is blurry.
Here we switch to 'dvivgm
#+begin_src emacs-lisp
(setq org-latex-create-formula-image-program 'dvisvgm)
#+end_src
* Looks
** Theme
#+BEGIN_SRC emacs-lisp

#+END_SRC
** Font
#+BEGIN_SRC emacs-lisp

#+END_SRC
* UI
** Starutp Screen
Disable the startup screen
#+BEGIN_SRC emacs-lisp
(setq inhibit-startup-screen t)
(setq inhibit-startup-message t)
(setq inhibit-startup-echo-area-message t)
#+END_SRC
** Bars
Disable the menu bar, tool bar, and scroll bar.
#+BEGIN_SRC emacs-lisp
(menu-bar-mode -1)
(tool-bar-mode -1)
(scroll-bar-mode -1)
#+END_SRC
** Cursor
Disable the blinking cursor
#+BEGIN_SRC emacs-lisp
(blink-cursor-mode -1)
#+END_SRC
** Scrolling
Scroll only one line (instead of jumping like it does by default)
#+BEGIN_SRC emacs-lisp
(setq scroll-conservatively most-positive-fixnum)
#+END_SRC
** Line Numbers
Display line numbers, and let the current line be 0 instead of its actual value
#+BEGIN_SRC emacs-lisp
(setq display-line-numbers-type 'relative
display-line-numbers-current-absolute 'nil)
(global-display-line-numbers-mode t)
#+END_SRC
** Bell
The bell sound is so annoying to me. Disable it.
Future consideration: visible bell is available, but it is big and ugly. Maybe customize in the future.
#+BEGIN_SRC emacs-lisp
(setq ring-bell-function 'ignore)
#+END_SRC
* UX
** Org Agenda
Custom org agenda views
#+begin_src emacs-lisp
(setq org-agenda-custom-commands
'(("w" "my weekly" agenda ""
((org-agenda-span 365)
(org-agenda-time-grid nil)
(org-agenda-repeating-timestamp-show-all t)
(org-agenda-entry-types '(:timestamp :sexp))))
))
#+end_src
* Languages
#+BEGIN_SRC emacs-lisp
(org-babel-do-load-languages
'org-babel-load-languages
'((python . t)))
#+END_SRC
configure python
#+begin_src emacs-lisp
(setq python-indent-offset 4
python-indent-guess-indent-offset 'nil)
#+end_src
