* Misc

** Lexical bindings

Enable lexical binding, of course...

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

** Dir local variables

Disable these because I don't use them and don't want to get prompted by them in
some projects.

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

** Taking SVG screenshots

Since Emacs 27, we can take SVG screenshots! Emacs needs to be built with
=cairo= to support this.

#+begin_src emacs-lisp
(defun screenshot-svg ()
  "Save a screenshot of the current frame as an SVG image.
Saves to a temp file and puts the filename in the kill ring."
  (interactive)
  (let* ((filename (make-temp-file "Emacs" nil ".svg"))
         (data (x-export-frames nil 'svg)))
    (with-temp-file filename
      (insert data))
    (kill-new filename)
    (message filename)))
#+end_src

* Theme

** Main 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-solarized-light)
#+END_SRC

** Dark theme toggle

I've come to prefer using a light theme during the day, and a dark theme at
night. Using a dark theme with daylight leads to cranking up the screen
brightness, which hurts my eyes more than using the light theme.

Set my light and dark themes:

#+BEGIN_SRC emacs-lisp
(setq my/light-theme doom-theme
      my/dark-theme 'doom-one)
#+END_SRC

Function to toggle between the two easily:

#+BEGIN_SRC emacs-lisp
(defun my/toggle-dark-theme ()
  (interactive)
  (if (eq my/dark-theme doom-theme)
      (load-theme my/light-theme t)
    (load-theme my/dark-theme t)))
#+END_SRC

Bind this to =SPC t d=:

#+BEGIN_SRC emacs-lisp
(map! :leader
      (:prefix-map ("t" . "toggle")
       :desc "Dark theme" "d" #'my/toggle-dark-theme))
#+END_SRC

** 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 "Input Mono Narrow" :size 12 :style 'regular))
#+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

** Battery indicator

I'm on a laptop, so let's display my battery in the modeline:

#+BEGIN_SRC emacs-lisp
(display-battery-mode 1)
#+END_SRC

* Programming

** Smart parens

Disable smart parens because half of the time it doesn't do what I want:

#+BEGIN_SRC emacs-lisp
(remove-hook 'doom-first-buffer-hook #'smartparens-global-mode)
#+END_SRC

** Rust

*** Column width

=rustfmt= limits lines to 100 characters, let's display it correctly.

#+BEGIN_SRC emacs-lisp
(add-hook! rustic-mode
  (set-fill-column 100))
#+END_SRC

*** Run clippy in rust-analyzer

The default is ~"check"~, but I want clippy lints as well.

#+begin_src emacs-lisp
(setq lsp-rust-analyzer-cargo-watch-command "clippy")
#+end_src

** C/C++

*** Default style

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

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

* Org mode

** Directory

Set a default directory for all my org-mode files.

#+BEGIN_SRC emacs-lisp
(setq org-directory "~/org/")
#+END_SRC

** Appearance

*** Disable fancy stars

#+BEGIN_SRC emacs-lisp
(remove-hook 'org-mode-hook #'org-superstar-mode)
#+END_SRC

*** Don't hide leading stars

Currently doesn't work due to [[https://github.com/hlissner/doom-emacs/issues/3076][hlissner/doom-emacs#3076]]

#+BEGIN_SRC emacs-lisp
(after! org
  (setq org-hide-leading-stars nil
        org-startup-indented nil
        org-adapt-indentation nil))
#+END_SRC

*** Fancier ellipsis indicator

#+BEGIN_SRC emacs-lisp
(setq org-ellipsis " ▼ ")
#+END_SRC

** Agenda setup

*** Default task keywords

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                                         |
| =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)"
           "|"
           "DONE(d!)"
           "CANCELLED(c@/!)")
          (sequence
           "[ ](T)"
           "|"
           "[X](D)"))))
#+END_SRC

*** Org capture setup

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" "New entry" entry (file "inbox.org")
           "* TODO %?")
          ("T" "Task" entry (file+headline "tasks.org" "Misc")
           "* TODO %?")
          ("r" "Reading" entry (file "reading.org")
           "* TODO %x"
           :immediate-finish t)
          ("w" "Watching" entry (file "watching.org")
           "* TODO %x"
           :immediate-finish t))))
#+END_SRC

I also change [[https://github.com/hlissner/doom-emacs/blob/134554dd69d9b1cea3d2190422de580fddf40ecd/modules/config/default/%2Bevil-bindings.el#L265][the default Doom binding]] for ~#'org-capture~ to be =SPC x= instead
of =SPC X=. Also need to rebind what was [[https://github.com/hlissner/doom-emacs/blob/134554dd69d9b1cea3d2190422de580fddf40ecd/modules/config/default/%2Bevil-bindings.el#L264][previously bound]] to =SPC x=, to =SPC
X=.

#+BEGIN_SRC emacs-lisp
(map! :leader
      :desc "Org Capture"           "x" #'org-capture
      :desc "Pop up scratch buffer" "X" #'doom/open-scratch-buffer)
#+END_SRC

*** Main agenda view

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"
                                       ))
                   (org-agenda-skip-function '(org-agenda-skip-entry-if 'deadline
                                                                        'scheduled))))
            (todo "TODO"
                  ((org-agenda-overriding-header "Assistant")
                   (org-agenda-files '("~/org/assistant.org"))
                   (org-agenda-skip-function '(org-agenda-skip-entry-if 'deadline
                                                                        'scheduled))))
            (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/watching.org"))
                   (org-agenda-overriding-header "To Watch")))
            (todo "TODO"
                  ((org-agenda-files '("~/org/reading.org"))
                   (org-agenda-overriding-header "To Read")))
            (todo "TODO"
                  ((org-agenda-files '("~/org/notes.org"))
                   (org-agenda-overriding-header "Note Taking")))
            (todo "TODO"
                  ((org-agenda-files '("~/org/project.org"))
                   (org-agenda-overriding-header "Personal projects")))
            )))))
#+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

*** Habits

Let's enable the =org-habit= module:

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

*** Save all org buffers shortcut

By default bound to =C-x C-s=, rebind it to =SPC m s= in =org-agenda-mode= :

#+BEGIN_SRC emacs-lisp
(map! :after org-agenda
      :map org-agenda-mode-map
      :localleader
      "s" #'org-save-all-org-buffers)
#+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]].

*** Roam Directory

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

*** Graph browser

Instruct =org-roam= to use =firefox-developer-edition= to open the graph:

#+BEGIN_SRC emacs-lisp
(setq org-roam-graph-viewer (executable-find "firefox-developer-edition"))
#+END_SRC

*** Roam link font face

Change link color for =org-roam= links, to distinguish them from standard Org
links:

#+BEGIN_SRC emacs-lisp
(after! org-roam
  (set-face-attribute 'org-roam-link nil :foreground "#FF8860"))
#+END_SRC

*** Roam capture template

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
  (setq org-roam-capture-templates
        '(("d" "default" plain (function org-roam-capture--get-point)
           "%?"
           :file-name "${slug}"
           :head "#+TITLE: ${title}\n"
           :unnarrowed t)
          ("i" "instant" plain (function org-roam-capture--get-point)
           "%?"
           :file-name "${slug}"
           :head "#+TITLE: ${title}\n"
           :unnarrowed t
           :immediate-finish t)
          ("w" "website" plain (function org-roam-capture--get-point)
           ""
           :file-name "websites/${slug}"
           :head "#+TITLE: ${title}\n#+ROAM_KEY: %x\n"
           :unnarrowed t)
          ("p" "paper" plain (function org-roam-capture--get-point)
           "%?"
           :file-name "papers/${slug}"
           :head "#+TITLE: ${title}\n"
           :unnarrowed t))))
#+END_SRC

**** Roam daily capture templates

Also setup daily captures templates, mainly used to store them in a =journal/=
directory instead of at the root.

#+BEGIN_SRC emacs-lisp
(after! org-roam
  (setq org-roam-dailies-capture-templates
        '(("d" "daily" plain (function org-roam-capture--get-point)
           ""
           :immediate-finish t
           :file-name "journal/%<%Y-%m-%d>"
           :head "#+TITLE: %<%Y-%m-%d>"))))
#+END_SRC

*** Org Roam Server

=org-roam-server= provides a fancy JS interface to visualize the graph. Just
needs to be loaded, along with its dependency =simple-httpd=.

#+BEGIN_SRC emacs-lisp
(use-package! simple-httpd)
(use-package! org-roam-server)
#+END_SRC

** Export backends

Sometimes I need to export an Org subtree to a file, which is quite easy with
the =org= export backend. It doesn't seem to be enabled by default, so let's add
it to the list:

#+BEGIN_SRC emacs-lisp
(after! org
  (add-to-list 'org-export-backends 'org))
#+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

* Magit

#+BEGIN_SRC emacs-lisp
(after! magit
  (transient-append-suffix 'magit-push "-n"
    '(4 "-s" "Skip GitLab CI" "--push-option=ci.skip")))
#+END_SRC
