* Misc

Enable lexical binding, of course...

#+BEGIN_SRC emacs-lisp
;;; -*- lexical-binding: t; -*-
#+END_SRC

#+BEGIN_SRC emacs-lisp
(setq enable-dir-local-variables nil)
#+END_SRC

* Appearance

** Font

Doom exposes five (optional) variables for controlling fonts in Doom. Here are
the three important ones:

- =doom-font=
- =doom-variable-pitch-font=
- =doom-big-font= -- used for =doom-big-font-mode=; use this for presentations
  or streaming.

They all accept either a font-spec, font string (=Input Mono-12=), or xlfd font
string. You generally only need these two:

#+BEGIN_SRC emacs-lisp
(setq doom-font (font-spec :family "Fira Mono Medium" :size 12))
#+END_SRC

** Theme

A list of all doom themes can be found here:

https://github.com/hlissner/emacs-doom-themes

#+BEGIN_SRC emacs-lisp
(setq doom-theme 'doom-one)
#+END_SRC

** Line numbers

Possible values of =display-line-numbers-type= are =nil=, =t=, and ='relative=.

#+BEGIN_SRC emacs-lisp
(setq display-line-numbers-type 'relative)
#+END_SRC

* Programming

** LSP

Doom disables documentation display in child frames by default; I like those, so
re-enable them, and reset [[https://github.com/emacs-lsp/lsp-ui/blob/242dfe859c3497c456eaacfd84942e12419529fe/lsp-ui-doc.el#L84][the defaults]].

#+BEGIN_SRC emacs-lisp
(after! lsp-ui
  (setq lsp-ui-doc-max-width 150)
  (setq lsp-ui-doc-max-height 30)
  (setq lsp-ui-doc-enable t))
#+END_SRC

** Rust

By default =rustic-mode= uses =rls=, I want to use =rust-analyzer= instead.

#+BEGIN_SRC emacs-lisp
(setq rustic-lsp-server 'rust-analyzer)
#+END_SRC

I don't want to enable format-on-save globally in Doom, but having it in rust is
nice.

#+BEGIN_SRC emacs-lisp
(after! rustic
  (setq rustic-format-trigger 'on-save))
#+END_SRC

** C/C++

Setup the default format for C/C++ editing.

#+BEGIN_SRC emacs-lisp
(setq c-default-style "gnu")
(setq c-basic-offset 2)
#+END_SRC

Flycheck never works well for C / C++ without configuration or a CMake build
system. Let's disable it.

#+BEGIN_SRC emacs-lisp
(after! flycheck
  (setq flycheck-global-modes '(not c-mode c++-mode)))
#+END_SRC

* Org mode

** Agenda setup

I want the default agenda view to be a daily view, with a log of what I've done
during the day.

#+BEGIN_SRC emacs-lisp
(after! org
  (setq org-agenda-span 'day)
  (setq org-agenda-start-with-log-mode t))
#+END_SRC

** Journal

For [[https://github.com/bastibe/org-journal][org-journal]] I want weekly entries (the default is ='daily=).

#+BEGIN_SRC emacs-lisp
(after! org-journal
  (setq org-journal-file-type 'weekly))
#+END_SRC

** Doom specific

Doom replaces the default tab behavior on headings, this restores the default
one. Taken from [[https://github.com/hlissner/doom-emacs/tree/develop/modules/lang/org#hacks][here]].

#+BEGIN_SRC emacs-lisp
(after! evil-org
  (remove-hook 'org-tab-first-hook #'+org-cycle-only-current-subtree-h))
#+END_SRC
