                     (projects . 5)
                     (agenda . 5)))
  (initial-buffer-choice (lambda () (get-buffer-create "*dashboard*")))

4.3. Load general

(use-package general)

4.4. Completion Framework

4.4.1. Selectrum

Use selectrum for a nicer completion buffer. Github

(use-package selectrum

  (:keymaps 'selectrum-minibuffer-map
   "C-j" 'selectrum-next-candidate
   "C-k" 'selectrum-previous-candidate))

4.4.2. Completion Style: Orderless

Use the orderless package to manage how filtering is done in the completion buffer. Github

(use-package orderless
  :custom (completion-styles '(orderless)))

4.4.3. Consult

Use consult to get some nicer commands for certain things. Github

(use-package consult
  (:states '(normal visual insert emacs)
           :prefix "SPC"
           :non-normal-prefix "C-SPC"
           :keymaps 'override
           ;; yank pop
           "yp" 'consult-yank-pop
                 ;; errors
           "El" 'consult-flymake))

4.4.5. Marginalia Icons

(use-package all-the-icons)
(use-package all-the-icons-completion
  :init (all-the-icons-completion-marginalia-setup))

4.4.6. Old Ivy configuration

  1. Ivy

    Let's use ivy as the completion framework. It's nice and simple

    ;; (use-package ivy
    ;;   :diminish
    ;;   :bind (:map ivy-minibuffer-map
    ;;            ("TAB" . ivy-alt-done) ; make ivy more vim friendly
    ;;            ("C-j" . ivy-next-line)
    ;;            ("C-k" . ivy-previous-line)
    ;;            ("C-h" . ivy-backward-delete-char)
    ;;            :map ivy-switch-buffer-map
    ;;            ("C-k" . ivy-previous-line)
    ;;            ("C-d" . ivy-switch-buffer-kill))
    ;;   :custom
    ;;   ((ivy-count-format "")
    ;;    (ivy-use-virtual-buffer t)
    ;;    (ivy-initial-inputs-alist nil))
    ;;   :config
    ;;   (ivy-mode 1))
  2. Ivy Rich


    ;; (use-package all-the-icons-ivy-rich
    ;;   :init (all-the-icons-ivy-rich-mode 1))

    Adds some nice extra information to ivy buffers

    ;; (use-package ivy-rich
    ;;   :diminish
    ;;   :after (ivy)
    ;;   :config
    ;;   (ivy-rich-mode 1))
  3. Counsel
    ;; (use-package counsel)
  4. Swiper
    ;; (use-package swiper)
  5. Prescient

    Prescient mode for ivy makes ivy use sorting by recents instead of whatever other order ivy uses by default.

    ;; (use-package ivy-prescient
    ;;   :config
    ;;   (ivy-prescient-mode))

4.5. Helpful

Provides prettier help functions

(use-package helpful
  (:states '(normal visual emacs)

           "d." 'helpful-symbol
           "df" 'helpful-function
           "dv" 'helpful-variable

           "dc" 'helpful-command)
  (defvar read-symbol-positions-list nil))

4.6. Keybindings

4.6.1. Which key

;; use which-key package so that keybindings are easier to rememeber
(use-package which-key
  :config (which-key-mode))

4.6.2. Evil

  1. Basic evil
    (use-package evil
      (setq evil-want-keybinding nil)
      (setq evil-want-C-u-scroll t)
      (evil-want-C-i-jump nil)
      :config (evil-mode 1) ;; activate evil mode
      ;; set the colors of the cursor
      (setq evil-emacs-state-cursor '("#fb4933" box)) 
      (setq evil-normal-state-cursor '("#fabd2f" box))
      (setq evil-visual-state-cursor '("#83a598" box))
      (setq evil-insert-state-cursor '("#b8bb26" bar))
      (setq evil-replace-state-cursor '("#fb4933" box))
      (setq evil-operator-state-cursor '("#d3869b" hollow))

      (evil-collection-calendar-want-org-bindings t)
      (evil-collection-setup-minibuffer nil)
  3. Evil Surround

    Provide nice keybindings for surrounding phrases with delimiters

    (use-package evil-surround

       :states 'visual
       "s" 'evil-surround-region)
      ;; make the mode active everywhere
      (global-evil-surround-mode 1))

       "Td" '(sgt/load-theme-dark :which-key "Dark")
       "Tc" '(load-theme :which-key "Custom"))

4.7. Undo tree

The default undo behavior in emacs is quite confusing. Use undo-tree instead.

(use-package undo-tree
  (undo-tree-auto-save-history nil)
  (global-undo-tree-mode 1))

4.8. Ranger

  ;; Optionally replace the key help with a completing-read interface
  (setq prefix-help-command #'embark-prefix-help-command)

  ;; Hide the mode line of the Embark live/completions buffers

;; Consult users will also want the embark-consult package.
(use-package embark-consult
  :ensure t
  :after (embark consult)
  :demand t ; only necessary if you have the hook below
  ;; if you want to have consult previews as you move around an
  ;; auto-updating embark collect buffer
  (embark-collect-mode . consult-preview-at-point-mode))

5. Development

5.1. Compiling

(use-package compile
  :straight nil
  (compilation-scroll-output t))

5.2. Commenting

Better commenting with evil-nerd-commenter

(use-package evil-nerd-commenter
  :after (evil evil-collection)
  (:states '(normal visual)
           "gc" 'evilnc-comment-operator))

5.3. Completion at point

I'm trying out corfu in place of company.

(use-package corfu
  (:keymap 'corfu-map
            :states '(insert normal emacs)
            "C-j" 'corfu-next
            "C-k" 'corfu-previous
            "M-d" 'corfu-show-documentation)

  (corfu-auto t)
  (corfu-echo-documentation t)
  (corfu-cycle t)
  (lsp-completion-provider :none)

  :init (corfu-global-mode))

Get documentation in my corfu completions.

(use-package corfu-doc
  :straight (corfu-doc :type git :host github :repo "galeo/corfu-doc")
  :after corfu
  :general (:keymaps 'corfu-map
                     ;; This is a manual toggle for the documentation window.
                     [remap corfu-show-documentation] #'corfu-doc-toggle

  (corfu-doc-delay 0.5)
  (corfu-doc-max-width 70)
  (corfu-doc-max-height 20)
  (corfu-echo-documentation t)

5.4. Project Management

5.4.1. Projectile

(use-package projectile
  :diminish projectile-mode
  :config (projectile-mode)
   :states '(normal visual insert emacs)
   :prefix "SPC"
   :non-normal-prefix "C-SPC"

   "p" '(:ignore t :which-key "Projects")
   "pf" 'project-find-file
   ;; "pa" 'projectile-add-known-project

;; (use-package counsel-projectile

5.4.2. Project.el

(use-package project

   "p'" 'project-eshell
   "pc" 'project-compile
   "p!" 'project-shell-command
   "p&" 'project-async-shell-command))

Tell project.el how to find the root of rust projects. This method is pretty slow rn. I should find a way to speed this up. Maybe caching the results would work?

(defun sgt/project-try-cargo-toml (dir)
  "Try to locate a Rust project."
  (let ((found (locate-dominating-file dir "Cargo.toml")))
     (if (stringp found)`(transient . ,found) nil)))

;; Try rust projects before version-control (vc) projects

5.10.2. Eshell custom functions

Function that goes up one directory. This will be bound to C-h

(defun sgt/eshell-up-dir ()
  (eshell/cd "..")

5.10.3. Some eshell keybindings.

EShell only loads its keybindings after the mode is loaded. This is annoying and means that we have to load custom keybindings using a hook.

(defun sgt/setup-eshell-keybindings ()
  (projectile-mode -1)
   :keymaps 'eshell-mode-map
   :states '(normal visual insert)
   "C-l" 'eshell/clear

   :states '(normal visual)
   :prefix ","
   "k" 'eshell-life-is-too-much
   "t" 'eshell-truncate-buffer))
(use-package eshell
  :hook (eshell-mode . sgt/setup-eshell-keybindings)
  ;; some stuff to attempt to speed up eshell + tramp
  (setq remote-file-name-inhibit-cache nil)
  (setq vc-ignore-dir-regexp (format "%s\\|%s"
  (setq tramp-verbose 6))
(use-package eshell-syntax-highlighting
  :after esh-mode
  ;; Enable in all Eshell buffers.
  (eshell-syntax-highlighting-global-mode +1))

5.10.4. TRAMP shell configuration

By default, TRAMP doesn't respect the remote path. This makes it hard to actually use an SSH session with EShell because no software if available.

(require 'tramp)
(add-to-list 'tramp-remote-path 'tramp-own-remote-path)
(setq tramp-default-method "ssh")

5.10.5. Mac configuration

(use-package exec-path-from-shell
