#+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
