* 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 my/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 "Iosevka Fixed" :size 10.0 :weight 'medium))
#+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

** Tridactyl mode

#+begin_src emacs-lisp
(defvar tridactylrc-font-lock-keywords
  `(    ;; Line comment
    ("^[\t ]*\\(\"\\)\\(.*\\)$"
     (1 font-lock-comment-delimiter-face)
     (2 font-lock-comment-face))

    ;; Trailing comment
    ("[\t ]+\\(\"\\)\\([^\"\r\n]*\\)$"
     (1 font-lock-comment-delimiter-face)
     (2 font-lock-comment-face))

    ;; String start:
    ("\\(\"[^\n\r\"]*\"\\)\\|\\('[^\n\r]*'\\)"
     (0 font-lock-string-face)) ;; String end;
    ))

(defvar tridactylrc-mode-syntax-table
  (let ((table (make-syntax-table)))
    (modify-syntax-entry ?'  "\"" table)
    (modify-syntax-entry ?\" "<"  table)
    (modify-syntax-entry ?\n ">"  table)
    table))

(define-derived-mode tridactylrc-mode prog-mode "tridactylrc"
  "Major mode for editing tridactylrc configuration files."
  :group 'tridactylrc-mode
  :syntax-table tridactylrc-mode-syntax-table
  (font-lock-add-keywords nil tridactylrc-font-lock-keywords)
  (setq-local comment-start "\"")
  (setq-local comment-end ""))
#+end_src

** 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

*** Enable proc macro support

By default lsp-mode disable these, I want them.

#+begin_src emacs-lisp
(setq lsp-rust-analyzer-experimental-proc-attr-macros t)
(setq lsp-rust-analyzer-proc-macro-enable t)
#+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

** Nix

*** Formatting

Use [[https://github.com/kamadorueda/alejandra][alejandra]] to format Nix code.

#+begin_src emacs-lisp
(set-formatter! 'alejandra "alejandra --quiet" :modes '(nix-mode))
#+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

*** Fancier ellipsis indicator

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

** Logging

Log state changes in a src_org{:LOGBOOK:} drawer so that it doesn't pollute the main content.

#+begin_src emacs-lisp
(after! org
  (setq org-log-into-drawer t))
#+end_src

** Archiving

I don't want to see archival files appearing when listing files in the current
directory, so hide them by default.

#+begin_src emacs-lisp
(after! org
  (setq org-archive-location ".%s_archive::"))
#+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 "Job")
                   (org-agenda-files '("~/org/job.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))))
            )))))
#+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

*** Script to open agenda window automatically

I use this script to automatically open the agenda when pressing a specific key binding in my window manager.

#+begin_src emacs-lisp :tangle "launch-agenda.el"
(find-file org-directory)
(with-selected-window (split-window-horizontally)
  ;; need to wait for the window to appear
  (sleep-for 0.1)
  (org-agenda nil " "))
#+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

*** org-roam-ui

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

#+begin_src emacs-lisp
(use-package! websocket
    :after org-roam)

(use-package! org-roam-ui
    :after org-roam
    :config (setq org-roam-ui-sync-theme t
                  org-roam-ui-follow t
                  org-roam-ui-update-on-save t
                  org-roam-ui-open-on-start t))
#+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 makes some changes to org-id behaviour which I don't like / think are necessary.

#+begin_src emacs-lisp
(after! org
  (setq org-id-locations-file (expand-file-name "~/.config/emacs/.org-id-locations"))
  (setq org-id-locations-file-relative nil))
#+end_src

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

*** Bugfix

Fix a bug with capture mode not working correctly when agenda is opened, stolen
from https://github.com/hlissner/doom-emacs/issues/5714#issuecomment-1018788028

#+begin_src emacs-lisp
(after! org
  (defadvice! dan/+org--restart-mode-h-careful-restart (fn &rest args)
    :around #'+org--restart-mode-h
    (let ((old-org-capture-current-plist (and (bound-and-true-p org-capture-mode)
                                              (bound-and-true-p org-capture-current-plist))))
      (apply fn args)
      (when old-org-capture-current-plist
        (setq-local org-capture-current-plist old-org-capture-current-plist)
        (org-capture-mode +1)))))
#+end_src

* Magit

** Gitlab CI skip flag

This option tells GitLab to skip the CI run for this push, in case I know it's
not ready yet.

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

GitLab push options are documented [[https://docs.gitlab.com/ee/user/project/push_options.html][here]].

** magit-delta

#+begin_src emacs-lisp
(use-package! magit-delta
  :hook (magit-mode . magit-delta-mode))
#+end_src

* Email

#+begin_src emacs-lisp :noweb no-export
(after! mu4e
  <<after-mu4e>>)
#+end_src

** Account configuration

This setting instructs =mu4e= to prompt for login credentials if none are found
when trying to connect to one of the servers that match the regex (see variable
documentation).

#+begin_src emacs-lisp
(setq smtpmail-servers-requiring-authorization "smtp.migadu.com\\|smtp.lrde.epita.fr")
#+end_src

Setup my main email account.

#+begin_src emacs-lisp
(set-email-account! "alarsyo"
  '((mu4e-sent-folder       . "/alarsyo/Sent")
    (mu4e-drafts-folder     . "/alarsyo/Drafts")
    (mu4e-refile-folder     . "/alarsyo/Archive")
    (mu4e-trash-folder      . "/alarsyo/Trash")
    (user-mail-address      . "antoine@alarsyo.net")
    (user-full-name         . "Antoine Martin")
    (mu4e-compose-signature . "Antoine Martin"))
  t)

(set-email-account! "lrde"
  '((mu4e-sent-folder       . "/lrde/Sent")
    (mu4e-drafts-folder     . "/lrde/Drafts")
    (mu4e-trash-folder      . "/lrde/Trash")
    (user-mail-address      . "amartin@lrde.epita.fr")
    (user-full-name         . "Antoine Martin")
    (mu4e-compose-signature . "Antoine Martin"))
  nil)
#+end_src

** Sending mail

I use =msmtp= as a SMTP forwarder

#+begin_src emacs-lisp :noweb-ref after-mu4e :tangle no
(setq sendmail-program (executable-find "msmtp")
      send-mail-function #'smtpmail-send-it
      message-sendmail-f-is-evil t
      message-sendmail-extra-arguments '("--read-envelope-from")
      message-send-mail-function #'message-send-mail-with-sendmail)
#+end_src

** Reading plain text

Ask the =gnus-view= (default viewer used by =mu4e=) to avoid HTML whenever
possible.

#+begin_src emacs-lisp :noweb-ref after-mu4e :tangle no
(add-to-list 'mm-discouraged-alternatives "text/html")
(add-to-list 'mm-discouraged-alternatives "text/richtext")
#+end_src

** Disable =org-msg= by default

Doom adds a hook, making it impossible to disable. This allows us to toggle it
manually.

#+begin_src emacs-lisp
(after! org-msg
  (setq +mu4e-compose-org-msg-toggle-next nil))
#+end_src

** Message quoting style

Has to be duplicated because =mu4e= doesn't use ~message-cite-style~'s values.

#+begin_src emacs-lisp
(defconst message-cite-style-custom
  '((message-cite-function          'message-cite-original-without-signature)
    (message-citation-line-function 'message-insert-formatted-citation-line)
    (message-cite-reply-position    'traditional)
    (message-yank-prefix            "> ")
    (message-yank-cited-prefix      "> ")
    (message-yank-empty-prefix      ">")
    (message-citation-line-format   "%f writes:"))
  "Message citation style used for email. Use with `message-cite-style'.")

(after! message
  (setq message-cite-style message-cite-style-custom
        message-cite-function          'message-cite-original-without-signature
        message-citation-line-function 'message-insert-formatted-citation-line
        message-cite-reply-position    'traditional
        message-yank-prefix            "> "
        message-yank-cited-prefix      "> "
        message-yank-empty-prefix      ">"
        message-citation-line-format   "%f writes:"))
#+end_src

** Disable format=flowed

#+begin_src emacs-lisp :noweb-ref after-mu4e :tangle no
(setq mu4e-compose-format-flowed nil)
#+end_src

** Don't permanently delete when trashing mails

By default =mu4e= sets the =trashed= flag on emails trashed using the =d=
keybinding. This just replaces the action to just move the message to the trash
instead.

See https://github.com/djcb/mu/issues/1136#issuecomment-1066303788, the code
will have to be adapted soon.

#+begin_src emacs-lisp :noweb-ref after-mu4e :tangle no
(setf (alist-get 'trash mu4e-marks)
      (list :char '("d" . "▼")
            :prompt "dtrash"
            :dyn-target (lambda (target msg)

** Enable auto updates
=mu4e= refreshes my email in the background.

#+begin_src emacs-lisp :noweb-ref after-mu4e :tangle no
(setq mu4e-update-interval 900)
#+end_src

If it fetches new mail while I'm browsing some messages, it will refresh the
headers view, potentially loosing context (like some messages that got marked as
read because I skimmed over them, but that I don't want to see disappear yet).
So let's disable this automatic update of headers:

#+begin_src emacs-lisp :noweb-ref after-mu4e :tangle no
(setq mu4e-headers-auto-update nil)
#+end_src

** Ask which address to send with when composing a new mail

#+begin_src emacs-lisp :noweb-ref after-mu4e :tangle no
(setq mu4e-compose-context-policy 'ask)
#+end_src

** Only fetch main directories by default

I have a lot (100+) directories on my main email account, I only want to fetch
the "important" ones (i.e. those coming from real individuals, addressed to me
directly) when I ask for a refresh explicitely (updating everything in the
background is fine the rest of the time).

Let's define a new function that does just that:

#+begin_src emacs-lisp :noweb-ref after-mu4e :tangle no
(defun my/mu4e-update-main-mail-and-index (run-in-background)
  "Get mail for all folders, not just the main ones"
  (interactive "P")
  (let ((mu4e-get-mail-command "mbsync alarsyo-main lrde"))
    (mu4e-update-mail-and-index run-in-background)))
#+end_src

Let's also bind it to =u= in the main view, overriding the default binding
(which I'll remap to =U=).

#+begin_src emacs-lisp :noweb-ref after-mu4e :tangle no
(map! :map mu4e-main-mode-map
      :ne "u" #'my/mu4e-update-main-mail-and-index
      :ne "U" #'mu4e-update-mail-and-index)
#+end_src

** Headers view format

Use "french" date format in header view:

#+begin_src emacs-lisp :noweb-ref after-mu4e :tangle no
(setq mu4e-headers-date-format "%d/%m/%y")
#+end_src

Set the time display to 24h:

#+begin_src emacs-lisp :noweb-ref after-mu4e :tangle no
(setq mu4e-headers-time-format "%T")
#+end_src

Setup the headers view columns how I like them

#+begin_src emacs-lisp :noweb-ref after-mu4e :tangle no
(setq mu4e-headers-fields '((:account-stripe . 1)
                            ;; just enough room for dd/mm/yy or hh:mm:ss
                            (:human-date . 8)
                            (:flags . 6)
                            (:mailing-list . 30)
                            (:from-or-to . 30)
                            (:subject)))
#+end_src

** Message view fields

#+begin_src emacs-lisp :noweb-ref after-mu4e :tangle no
(setq mu4e-view-fields '(:from :to :cc :subject :flags :date :mailing-list :maildir :path :size :tags :attachments :user-agent :signature :decryption))
#+end_src

** Mailing list pretty names

#+begin_src emacs-lisp :noweb-ref after-mu4e :tangle no
(setq mu4e-mailing-list-patterns '("[0-9]+\\.\\(.+\\)\\.gitlab\\.lrde\\.epita\\.fr"
                                   "[0-9]+\\.\\(.+\\)\\.gitlab\\.com"
                                   "\\(.+\\)\\.github\\.com"))
#+end_src

** Fix attachment icon with light theme

#+begin_src emacs-lisp :noweb-ref after-mu4e :tangle no
