#+TITLE: Doom Emacs Configuration File

* Installation

Execute ~doom sync~ after modifying this file to tangle it to ~config.el~.

Dependencies:
- Doom Emacs: ~git~ ~ripgrep~, ~fd-find~
- ~lilypond-mode~: ~LilyPond~
- ~:app everywhere~: ~xwininfo~, ~xdotool~, ~xclip~, ~xprop~
- Font: Source Code Pro
Individual packages may have other optional dependencies. Execute ~doom doctor~ to find out.

The following block of comments is from the default configuration.

#+begin_src emacs-lisp
;;; $DOOMDIR/config.el -*- lexical-binding: t; -*-

;; Place your private configuration here! Remember, you do not need to run 'doom
;; sync' after modifying this file!

;; Whenever you reconfigure a package, make sure to wrap your config in an
;; `after!' block, otherwise Doom's defaults may override your settings. E.g.
;;
;;   (after! PACKAGE
;;     (setq x y))
;;
;; The exceptions to this rule:
;;
;;   - Setting file/directory variables (like `org-directory')
;;   - Setting variables which explicitly tell you to set them before their
;;     package is loaded (see 'C-h v VARIABLE' to look up their documentation).
;;   - Setting doom variables (which start with 'doom-' or '+').
;;
;; Here are some additional functions/macros that will help you configure Doom.
;;
;; - `load!' for loading external *.el files relative to this one
;; - `use-package!' for configuring packages
;; - `after!' for running code after a package has loaded
;; - `add-load-path!' for adding directories to the `load-path', relative to
;;   this file. Emacs searches the `load-path' when you load packages with
;;   `require' or `use-package'.
;; - `map!' for binding new keys
;;
;; To get information about any of these functions/macros, move the cursor over
;; the highlighted symbol at press 'K' (non-evil users must press 'C-c c k').
;; This will open documentation for it, including demos of how they are used.
;; Alternatively, use `C-h o' to look up a symbol (functions, variables, faces,
;; etc).
;;
;; You can also try 'gd' (or 'C-c c d') to jump to their definition and see how
;; they are implemented.
#+end_src

These packages are loaded into ~packages.el~. The following comments are provided by default.

#+begin_src emacs-lisp :tangle packages.el
;; -*- no-byte-compile: t; -*-
;;; $DOOMDIR/packages.el

;; To install a package with Doom you must declare them here and run 'doom sync'
;; on the command line, then restart Emacs for the changes to take effect -- or
;; use 'M-x doom/reload'.


;; To install SOME-PACKAGE from MELPA, ELPA or emacsmirror:
;(package! some-package)

;; To install a package directly from a remote git repo, you must specify a
;; `:recipe'. You'll find documentation on what `:recipe' accepts here:
;; https://github.com/radian-software/straight.el#the-recipe-format
;(package! another-package
;  :recipe (:host github :repo "username/repo"))

;; If the package you are trying to install does not contain a PACKAGENAME.el
;; file, or is located in a subdirectory of the repo, you'll need to specify
;; `:files' in the `:recipe':
;(package! this-package
;  :recipe (:host github :repo "username/repo"
;           :files ("some-file.el" "src/lisp/*.el")))

;; If you'd like to disable a package included with Doom, you can do so here
;; with the `:disable' property:
;(package! builtin-package :disable t)

;; You can override the recipe of a built in package without having to specify
;; all the properties for `:recipe'. These will inherit the rest of its recipe
;; from Doom or MELPA/ELPA/Emacsmirror:
;(package! builtin-package :recipe (:nonrecursive t))
;(package! builtin-package-2 :recipe (:repo "myfork/package"))

;; Specify a `:branch' to install a package from a particular branch or tag.
;; This is required for some packages whose default branch isn't 'master' (which
;; our package manager can't deal with; see radian-software/straight.el#279)
;(package! builtin-package :recipe (:branch "develop"))

;; Use `:pin' to specify a particular commit to install.
;(package! builtin-package :pin "1a2b3c4d5e")


;; Doom's packages are pinned to a specific commit and updated from release to
;; release. The `unpin!' macro allows you to unpin single packages...
;(unpin! pinned-package)
;; ...or multiple packages
;(unpin! pinned-package another-pinned-package)
;; ...Or *all* packages (NOT RECOMMENDED; will likely break things)
;(unpin! t)
#+end_src


* User specific settings

Some functionality uses this to identify you, e.g. GPG configuration, email
clients, file templates and snippets. It is optional. This could be changed to
rely on system environment variables.

#+begin_src emacs-lisp
(setq
	user-full-name "Leni Aniva"
	user-mail-address "v@leni.sh")
#+end_src

If you use ~org~ and don't want your org files in the default location below,
change ~org-directory~. It must be set before org loads!

#+begin_src emacs-lisp
(setq org-directory "~/org/")
#+end_src

* Interface

** Key Bindings

Modifications to the default key bindings to mimic spacemacs

- ~SPC SPC~ is mapped to ~M-x~ (~#'execute-extended-command~)
- ~SPC !~ is mapped to ~M-!~ (~#'shell-command~)
- ~SPC :~ is mapped to ~M-:~ (~#'eval-expression~)
- ~,~ is mapped to the local (major mode) leader ~,~
- ~SPC b 0~ deletes the current buffer and window like Spacemacs ~SPC b x~

#+begin_src emacs-lisp
(setq doom-localleader-key ",")
(map! :leader
	:desc "Execute shell command"
	"!" #'shell-command)
(map! :leader
	:desc "Execute extended command (emacs M-x)"
	"SPC" #'execute-extended-command)
(map! :leader
	:desc "Evaluate expression (emacs M-:)"
	":" #'eval-expression)
(map! :leader
	:desc "Kill buffer and window"
	"b 0" #'kill-buffer-and-window)
(map! :leader
	(:prefix ("S" . "Set")
	 :desc "Input method" "i" #'set-input-method
	))
(map! :nvi "C" nil) ; remove this one weird binding

(map! "<f12>" #'toggle-input-method)

(global-set-key (kbd "M-|") (kbd "|"))
(global-set-key (kbd "C-M-¥") (kbd "C-\\"))
#+end_src

** Font settings

Doom exposes five (optional) variables for controlling fonts in Doom:

- ~doom-font~ -- the primary font to use
- ~doom-variable-pitch-font~ -- a non-monospace font (where applicable)
- ~doom-big-font~ -- used for ~doom-big-font-mode~; use this for
  presentations or streaming.
- ~doom-unicode-font~ -- for unicode glyphs
- ~doom-serif-font~ -- for the ~fixed-pitch-serif~ face

See ~C-h v doom-font~ for documentation and more examples of what they
accept.

If you or Emacs can't find your font, use ~M-x describe-font~ to look them up,
~M-x eval-region~ to execute ELisp code, and ~M-x doom/reload-font~ to refresh
your font settings. If Emacs still can't find your font, it likely wasn't
installed correctly. Font issues are rarely Doom issues!

There are two ways to load a theme. Both assume the theme is installed and
available. You can either set ~doom-theme~ or manually load a theme with the
~load-theme~ function.

#+begin_src emacs-lisp
(setq
	default-font "Source Code Pro"
	default-font-size 14.0
	doom-font (font-spec
		:family default-font
		:size default-font-size
		:weight 'semi-light)
	doom-variable-pitch-font (font-spec
		:family default-font
		:size (+ default-font-size 1.0))
	doom-unicode-font (font-spec
		:family default-font
		:size default-font-size)
	doom-theme 'doom-lantern)
;(add-to-list 'default-frame-alist '(alpha . 90))

** Splash Screen

#+begin_src emacs-lisp

	(let* (
			(banner (with-temp-buffer
				(insert-file-contents "~/.config/doom/banner.txt")
				(split-string (buffer-string) "\n" t)))
			(longest-line (apply #'max (mapcar #'length banner)))
		)
		(put-text-property
			(point)
			(dolist (line banner (point))
				(insert

(setq +doom-dashboard-ascii-banner-fn #'custom/doom-banner)
(set-face-font 'doom-dashboard-banner (font-spec :family "Source Code Pro" :foundry "ADBO"))
#+end_src

** Line numbers

This determines the style of line numbers in effect. If set to ~nil~, line
numbers are disabled. For relative line numbers, set this to ~relative~.

#+begin_src emacs-lisp
(setq display-line-numbers-type 'relative)
#+end_src

** Indentation Style Hooks

** Shells

#+begin_quote
Fish (and possibly other non-POSIX shells) is known to inject garbage
output into some of the child processes that Emacs spawns. Many Emacs
packages/utilities will choke on this output, causing unpredictable
issues.
#+end_quote

Here we set the default shell to ~bash~ but the vterm shell to the system
~$SHELL~ variable.

#+begin_src emacs-lisp
(setq shell-file-name (executable-find "bash"))
(setq vterm-shell (getenv "SHELL"))

*** LaTeX

The target indentation style of ~LaTeX~ is as follows:

#+begin_src tex :tangle no
\section{A section}
% No indent here

\begin{enumerate}[1.]
\item Some item 1. Note that item is not indented.

	Item 1 continued. 1 level of indentation.
\item
	\begin{tikzpicture}[
			xscale=2,yscale=3
		]
		\node[dot] (x) at (0,0);
		\node[dot] (y) at (0,1);
		\draw (x) -- (y)
			\node[midway,fill=white] {$f$};
	\end{tikzpicture}
\end{enumerate}
#+end_src

The ~SPC m c~ command which by default binds to ~TeX-command-run-all~ is
modified so it runs in the directory of the nearest ~.latexmkrc~ file or the
projectile root, whichever is closer. If a ~.latexmkrc~ file is not found, we
fall back to the current directory. We improve this below by decreeing that all
compilation has to happen with the ~.latexmkrc~ file's directory as PWD.
#+begin_src emacs-lisp
(defun custom/TeX-root-directory (start)
	(let* (
		(dir-latexmkrc (projectile-locate-dominating-file start ".latexmkrc"))
		(dir-projectile (projectile-project-root))
		(is-latexmk-child-of-projectile (and dir-projectile dir-latexmkrc
			(string-match-p (regexp-quote dir-projectile) dir-latexmkrc))))
		(cond
			((and dir-latexmkrc is-latexmk-child-of-projectile) dir-latexmkrc)
			(dir-projectile dir-projectile)
			(t start))))
(defun custom/TeX-master-directory-filter (dir-master)
	(custom/TeX-root-directory dir-master))
(defun custom/TeX-master-file-filter (file-master)
	(concat
		(string-remove-prefix (custom/TeX-root-directory default-directory) default-directory)

(advice-add 'TeX-master-file      :filter-return #'custom/TeX-master-file-filter)
#+end_src


For some reason the keymap binding has to use ~LaTeX-mode-map~ or ~TeX-mode-map~
instead of ~latex-mode-map~. Also some original keybindings are removed so they
can be displayed correctly in prompts. See e.g. ~tex-buf.el~ for an example.

When unbinding these keys, use ~:g~ flag to ensure no extraneous keys are
introduced.

*** Emacs IPython Notebook (ein)

Adapted from [[https://gist.github.com/millejoh/8632402a11384a3a0949fa350a1a271b]]

Usage: Since ~ein:notebooklist-mode~, ~ein:markdown-mode~, and
~ein:traceback-mode~ are major modes, their hotkeys are triggered by the local
leader ~,~ / ~SPC m~. However the ~ein:notebook-mode~ and
~ein:notebook-multilang-mode~ are minor modes and they are triggered by ~C-c~
instead of ~,~.

FIXME: Cleanup ~ein:markdown-mode-map~.
