* 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

Here are the [[https://orgmode.org/manual/TODO-Extensions.html#TODO-Extensions][keywords]] I'm using to track task progress. I'm also making use of
some automatic [[https://orgmode.org/manual/Tracking-TODO-state-changes.html#Tracking-TODO-state-changes][state changes]].

| keyword     | meaning                                                                  |
|-------------+--------------------------------------------------------------------------|
| =TODO=      | Self explanatory                                                         |
| =WAITING=   | I'm probably waiting on someone to do something before I can act on this |
| =DONE=      | This task is finished, no longer displayed in the agenda                 |
| =CANCELLED= | This task isn't finished but is no longer relevant                       |

#+BEGIN_SRC emacs-lisp
(after! org
  (setq org-todo-keywords
        '((sequence
           "TODO(t)"
           "WAITING(w@/!)"
           "|"
           "DONE(d!)"
           "CANCELLED(c@/!)")
          (sequence
           "[ ](T)"
           "[-](S)"
           "[?](W)"
           "|"
           "[X](D)"))))
#+END_SRC

Of course I also need to setup [[https://orgmode.org/manual/Capture-templates.html][capture templates]]:

The first one just prompts me for a new task to add to my inbox, I can then
[[https://orgmode.org/guide/Refile-and-Copy.html][refile]] them where I want later.

The second one exists because I like to keep a separate list of articles /
papers / books to read.

#+BEGIN_SRC emacs-lisp
(after! org
  (setq org-capture-templates
        '(("t" "Task" entry (file "inbox.org")
           "* TODO %?")
          ("r" "Reading" entry (file "reading.org")
           "* TODO %x"))))
#+END_SRC

All these tasks, once captured, are then centralized in my [[https://orgmode.org/guide/Agenda-Views.html][agenda view]].

I'm using multiple categories to organize tasks, depending on their triage /
status (inspired by [[https://blog.jethro.dev/posts/org_mode_workflow_preview/]]).

#+BEGIN_SRC emacs-lisp
(after! org-agenda
  (setq org-agenda-custom-commands
        '((" " "Agenda"
           ((agenda ""
                    ((org-agenda-span 'day)
                     (org-agenda-start-day nil)
                     (org-deadline-warning-days 365)))
            (todo "TODO"
                  ((org-agenda-overriding-header "Triage")
                   (org-agenda-files '("~/org/inbox.org"))))
            (todo "TODO"
                  ((org-agenda-overriding-header "School")
                   (org-agenda-files '(
                                       "~/org/image.org"
                                       "~/org/rdi.org"
                                       ))))
            (todo "TODO"
                  ((org-agenda-overriding-header "Tasks")
                   (org-agenda-files '("~/org/tasks.org"))
                   (org-agenda-skip-function '(org-agenda-skip-entry-if 'deadline
                                                                        'scheduled))))
            (todo "TODO"
                  ((org-agenda-files '("~/org/reading.org"))
                   (org-agenda-overriding-header "To Read")))
            )))))
#+END_SRC

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

#+BEGIN_SRC emacs-lisp
(after! org-agenda
  (setq org-agenda-span 'week)
  (setq org-agenda-start-on-weekday 1)
  (setq org-agenda-start-with-log-mode '(clock)))
#+END_SRC

I also remove the block separators in the agenda view:

#+BEGIN_SRC emacs-lisp
(after! org-agenda
  (setq org-agenda-block-separator ""))
#+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-date-format "%A (%d/%m/%Y)")
  (setq org-journal-file-type 'weekly)
  (setq org-journal-file-format "%Y-%m-%d.org")

  ;; see `org-journal-dir-and-format->regex' documentation
  (setq org-journal-file-pattern (org-journal-dir-and-format->regex
                                  org-journal-dir org-journal-file-format))
  (add-to-list 'auto-mode-alist (cons org-journal-file-pattern 'org-journal-mode)))
#+END_SRC

** Org IDs

Org can link to entries using UUIDs, but we need the module to be loaded for
links to work:

#+BEGIN_SRC emacs-lisp
(add-to-list 'org-modules 'org-id)
#+END_SRC

** Roam

Setup for [[https://github.com/jethrokuan/org-roam][org-roam]].

First, set a directory where =org-roam= will index things.

#+BEGIN_SRC emacs-lisp
(setq org-roam-directory (expand-file-name "notes/" org-directory))
#+END_SRC

Customize the capture templates:

- the first one is [[https://github.com/jethrokuan/org-roam/blob/772505ba70c073ebc7905c4fcb8b9cc3759c775a/org-roam-capture.el#L81][the default one]], I just removed the timestamp from the file
  title.
- the second one I use to create new entries about website links, blog posts,
  articles... The ~%x~ in the template is replaced by the content of my X
  clipboard, so I just have to copy the website URL before capturing it.


#+BEGIN_SRC emacs-lisp
(after! org-roam
  (set-face-attribute 'org-roam-link nil :foreground "#CCCC60")
  (setq org-roam-capture-templates
        '(("d" "default" plain (function org-roam-capture--get-point)
           "%?"
           :file-name "${slug}"
           :head "#+TITLE: ${title}\n"
           :unnarrowed t)
          ("w" "website" plain (function org-roam-capture--get-point)
           ""
           :file-name "websites/${slug}"
           :head "#+TITLE: ${title}\n#+ROAM_KEY: %x\n"
           :unnarrowed t))))
#+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
