This is a literate init file holding my Emacs configuration. It is initially loaded by a bootstrap file that lives at ~/.emacs.d/init.el; after the initial bootstrapping it writes itself to ~/.emacs.el. Since ~/.emacs.el takes priority over ~/.emacs.d/init.el, after the initial bootstrapping process the tangled ~/.emacs.el file will get loaded without needing to load the bootstrap file first.

Prelude

Enables lexical binding for everything in init.el:

  ;;;  -*- lexical-binding: t; -*-

Garbage collection

Some GC tweaks "borrowed" from Doom emacs.

Turn off GC during init and restore it afterwards:

  (setq gc-cons-threshold most-positive-fixnum
	gc-cons-percentage 0.6)

  (add-hook 'emacs-startup-hook
      (lambda ()
	(setq gc-cons-threshold 100000000
	      gc-cons-percentage 0.1)))

Also suppress GC for 1 second after the minibuffer is active to avoid stuttering autocompletion and other GC hangups:

  (defun defer-garbage-collection ()
    (setq gc-cons-threshold most-positive-fixnum))

  (defun restore-garbage-collection ()
    (run-at-time
     1 nil (lambda () (setq gc-cons-threshold 100000000))))

  (add-hook 'minibuffer-setup-hook #'defer-garbage-collection)
  (add-hook 'minibuffer-exit-hook #'restore-garbage-collection)

Unset file-handler-alist during initialization

Another optimization from Doom Emacs.

  (defvar file-name-handler-alist-backup file-name-handler-alist)
  (setq file-name-handler-alist nil)
  (add-hook 'emacs-startup-hook
	    (lambda ()
	      (setq file-name-handler-alist file-name-handler-alist-backup)))

Variables

  (setq vc-follow-symlinks t
        frame-resize-pixelwise t
        tab-always-indent 'complete
        enable-recursive-minibuffers t
        read-process-output-max (* 1024 1024)
        bookmark-save-flag 1)
  (setq-default indent-tabs-mode nil)

Default directory

  (cd "~")

Packages

Load straight.el to manage package installation:

  (defvar bootstrap-version)
  (unless (boundp 'bootstrapping-init)
   (let ((bootstrap-file
	 (expand-file-name "straight/repos/straight.el/bootstrap.el" user-emacs-directory))
	(bootstrap-version 5))
    (unless (file-exists-p bootstrap-file)
      (with-current-buffer
	  (url-retrieve-synchronously
	   "https://raw.githubusercontent.com/raxod502/straight.el/develop/install.el"
	   'silent 'inhibit-cookies)
	(goto-char (point-max))
	(eval-print-last-sexp)))
    (load bootstrap-file nil 'nomessage)))

`use-package` is a macro that simplifies installing and loading packages.

  (straight-use-package 'use-package)
  (setq straight-use-package-by-default t)

Utility functions

  (defun find-library-readme (library)
    (interactive (list (read-library-name)))
    (let* ((dir (file-name-directory (file-truename (find-library-name library))))
           (doc (car (directory-files dir t "\\(readme\\|README\\)\\..*"))))
      (if (not doc)
          (error "No README found")
        (find-file doc)
        (when (eq major-mode 'markdown-mode)
          (markdown-view-mode)))))

Benchmarking

`benchmark-init` does what it says on the box. This sets it up to benchmark my init time and then disable benchmarking after init completes.

  (use-package benchmark-init
    :config
    (add-hook 'after-init-hook 'benchmark-init/deactivate))

General

Better keybinding.

  (use-package general
    :init
    (setq general-override-states '(insert
				    emacs
				    hybrid
				    normal
				    visual
				    motion
				    operator
				    replace)))

Which-key

`which-key` makes keybindings discoverable.

  (use-package which-key
    :config
    (which-key-mode))

This function defines a prefix group for `which-key` so that it doesn't display `prefix`.

  (defun jdormit/define-prefix (binding name)
    (which-key-add-key-based-replacements
      (concat leader " " binding)
      name)
    (which-key-add-key-based-replacements
      (concat "," " " binding)
      name))

Evil Mode

Because I like modal editing and dislike RSI.

  (use-package evil
    :init
    (setq evil-want-keybinding nil)
    :config
    (evil-mode 1))

Make undo not undo paragraphs at a time:

  (setq evil-want-fine-undo t)

Add a convenience function for making buffer-local ex-commands:

  (defun evil-ex-define-local-cmd (cmd function)
    (set (make-local-variable 'evil-ex-commands) (copy-tree evil-ex-commands))
    (evil-ex-define-cmd cmd function))

evil-collection

A collection of evil bindings for various modes

  (use-package evil-collection
    :after (evil)
    :hook ((after-init . evil-collection-init))
    :config
    (setq evil-collection-company-use-tng nil))

leader key

Use the spacebar as a leader key in evil-mode's normal state and in various other modes:

  (defconst leader "SPC")
  (general-define-key
   :keymaps 'override
   :states '(normal visual motion)
   "SPC" nil)
  (general-create-definer leader-def-key
    :keymaps 'override
    :states '(normal visual motion)
    :prefix leader
    :prefix-map 'leader-map)
  (jdormit/define-prefix "?" "help")
  (leader-def-key "?" help-map)

evil-snipe

  (use-package evil-snipe
    :after (evil)
    :config
    (evil-snipe-mode 1)
    (evil-snipe-override-mode 1)
    (add-to-list 'evil-snipe-disabled-modes 'dired-mode)
    (add-to-list 'evil-snipe-disabled-modes 'structlog-mode)
    (with-eval-after-load 'magit
      (add-hook 'magit-mode-hook 'turn-off-evil-snipe-override-mode))
    (with-eval-after-load 'prodigy
      (add-hook 'prodigy-mode-hook 'turn-off-evil-snipe-mode))
    (with-eval-after-load 'pass
      (add-hook 'pass-mode-hook 'turn-off-evil-snipe-mode)))

evil-commentary

Adds Evil commands to comment out lines of code:

  (use-package evil-commentary
    :after (evil)
    :hook ((prog-mode . evil-commentary-mode)))

Additional keybindings

  (general-def 'normal "zM" #'hs-hide-level :keymaps 'override)
  (general-def 'normal "z=" #'text-scale-increase :keymaps 'override)
  (general-def 'normal "z-" #'text-scale-decrease :keymaps 'override)
  (general-def 'normal "z0" #'text-scale-adjust :keymaps 'override)
  (general-def 'normal view-mode-map "0" nil :keymaps 'override)
  (general-def 'normal prodigy-view-mode-map "0" nil :keymaps 'override)
  (general-def 'normal messages-buffer-mode-map "SPC" leader-map :keymaps 'override)

Hydra

Hydras are convenient keybinding menus.

  (use-package hydra
    :defer t)

Syncthing

I put lots of stuff in Dropbox, but the actual folder location differs on my different computers. This function resolves to the Dropbox directory:

  (defcustom syncthing-path (expand-file-name "~/Sync")
    "The absolute path to the Syncthing directory"
    :type 'directory)

  (defun syncthing-directory (&optional path)
    (f-join syncthing-path (s-chop-prefix (f-path-separator) (or path ""))))

Org Mode

Notes, agenda, calendar, blogging, journaling, etc.

Loaded early to avoid a version clash.

First, a function to get my notes directory:

  (defun org-directory (&optional path)
    "Returns the directory for my org notes, appends PATH if given"
    (f-join (syncthing-directory "org")
            (s-chop-prefix (f-path-separator) (or path ""))))
  (use-package org
    :straight org-plus-contrib
    :commands (org-element-map)
    :mode (("\\.org\\'" . org-mode))
    :init
    (jdormit/define-prefix "o" "org")
    (leader-def-key "oa" 'org-agenda)
    (leader-def-key "oc" 'org-capture)
    :config
    (defun agenda-files (&optional file)
      (let ((agenda-dir (org-directory)))
        (if file
            (concat (file-name-as-directory agenda-dir) file)
          agenda-dir)))

Exporting

HTML

Export to HTML:

  (use-package htmlize
    :commands htmlize-buffer)

Don't put section numbers in front of headers:

  (setq org-export-with-section-numbers nil)

Disable the preamble and postamble:

  (setq org-html-preamble nil
	org-html-postamble nil)

Redefine org-html-src-block to wrap code blocks in <pre><code> and language class for use by highlight.js:

  (defun org-html-src-block (src-block _contents info)
    "Transcode a SRC-BLOCK element from Org to HTML.
  CONTENTS holds the contents of the item.  INFO is a plist holding
  contextual information."

Display inline images after executing a source block:

  (add-hook 'org-babel-after-execute-hook
      (lambda ()

Enable async source block execution. Note: this execute the contents of the source block in a separate Emacs process, so blocks that rely on anything defined in init.org or the current Emacs process won't work as expected.

  (use-package ob-async
    :straight (ob-async :host github :repo "astahlman/ob-async")
    :defer t
    :hook (org-mode . (lambda () (require 'ob-async))))

Filter out the "u" from unicode results in org tabels returned from Python source blocks:

  If the results look like a list or tuple, then convert them into an

Doom themes

  (use-package doom-themes)

  (use-package doom-modeline)
  (doom-modeline-mode 1)

Ewal theme

  (use-package doom-ewal-themes
    :straight (doom-ewal-themes
	       :host github
	       :repo "jdormit/doom-ewal-themes"
	       :files ("themes" :defaults)))

Customization File

I don't want anything to write to my init.el, so save customizations in a separate file:

  (setq custom-file (expand-file-name "custom.el" user-emacs-directory))
  (load custom-file t)

Path

`exec-path-from-shell` uses Bash to set MANPATH, PATH, and exec-path from those defined in the user's shell config. This won't work on Windows.

  (use-package exec-path-from-shell
    :if (memq window-system '(mac ns x))
    :config
    (setq exec-path-from-shell-variables '("PATH" "MANPATH" "LEDGER_FILE" "LOLA_HOME"
                                           "MODELS_HOME" "LOLA_TRAVEL_SERVICE_HOME" "WORKON_HOME"
                                           "PIPENV_VERBOSITY" "PIPENV_DONT_LOAD_ENV"
                                           "PIPENV_MAX_DEPTH" "PYENV_ROOT")
          exec-path-from-shell-check-startup-files nil)
    (exec-path-from-shell-initialize))

Autocompletion

There seems to be some contention about whether autocomplete or company are better autocomplete packages. I'm going with company for now because the maintainer seems nicer…

  (use-package company
    :commands (company-complete
               company-mode)
    :hook ((prog-mode . company-mode))
    :config
    (setq company-idle-delay 0.3))

  (general-def "C-M-i" #'company-complete)
  (general-def "M-<tab>" #'company-complete)

Multiple cursors

  (use-package evil-mc
    :defer 0
    :config

      "M-n" #'evil-mc-make-and-goto-next-cursor
      "M-p" #'evil-mc-make-and-goto-prev-cursor
      "C-n" #'evil-mc-make-and-goto-next-match
      "C-t" #'evil-mc-skip-and-goto-next-match

    :config
    (evil-multiedit-default-keybinds))

Transient

A framework for creating Magit-style popups:

  (use-package transient
    :commands (define-transient-command))

Magit

Magit is objectively the best Git interface.

  (use-package magit
    :commands (magit-status
               magit-blame
               magit-find-file
               magit-name-local-branch))

  (leader-def-key "gs" #'magit-status)
  (leader-def-key "gg" #'magit-file-dispatch)
  (leader-def-key "gf" #'magit-find-file)

Use ido-mode for completion within Magit:

;;  (setq magit-completing-read-function 'magit-ido-completing-read)

Forge

Forge is an extension for Magit that lets it interact with code forges (e.g. GitHub).

  (use-package forge
    :after (magit)
    :config
    (add-to-list 'forge-alist '("git.jeremydormitzer.com"

     "q" #'quit-window)
    :custom
    (forge-owned-accounts '((jdormit . (remote-name "jdormit")))))

evil-magit

Evil keybindings for magit!

  (use-package evil-magit
    :after (evil magit)
    :config
    (with-eval-after-load 'magit
      (require 'evil-magit))
    :general
    ('normal magit-mode-map "SPC" leader-map))

Transient

  (setq transient-default-level 7)

git-link

Open files in Git forges (GitHub, GitLab, etc.):

  (use-package git-link
    :commands (git-link)
    :init
    (defun git-link-copy ()
      (interactive)
      (let ((git-link-open-in-browser nil))
        (call-interactively 'git-link)))
    (leader-def-key "gl" #'git-link)
    (leader-def-key "gy" #'git-link-copy)
    :custom
    (git-link-open-in-browser t)
    (git-link-remote-alist '(("git.sr.ht" git-link-sourcehut)
                             ("github" git-link-github)
                             ("bitbucket" git-link-bitbucket)
                             ("gitorious" git-link-gitorious)
                             ("gitlab" git-link-gitlab)
                             ("visualstudio\\|azure" git-link-azure)
                             ("git.jeremydormitzer.com" git-link-bitbucket))))

with-editor

A utility from the author of Magit to run shell commands using the current Emacs instance as $EDITOR.

  (shell-command-with-editor-mode)
  (add-hook 'shell-mode-hook #'with-editor-export-editor)
  (add-hook 'term-exec-hook #'with-editor-export-editor)
  (add-hook 'eshell-mode-hook #'with-editor-export-editor)

Password Store

Interfacing with Pass, the "standard Unix password manager". This should also be loaded before `exec-path-from-shell`.

  (defun password-store-synchronize ()
    (interactive)
    (with-editor-async-shell-command "pass git pull && pass git push"))

  (use-package password-store
    :defer t
    :if (executable-find "pass")
    :config
    (setq password-store-password-length 20)
    :init
    (leader-def-key "P" 'password-store-copy)
    (epa-file-enable))

  (use-package pass
    :if (executable-find "pass")
    :commands pass
    :general
    ('(normal motion visual) pass-mode-map "S" #'password-store-synchronize))

  (leader-def-key "ap" #'pass)

  (setq auth-sources '("~/.authinfo" password-store))

Load path

For machine or user specific libraries:

  (add-to-list 'load-path (expand-file-name "~/site-lisp"))

And for global ones:

  (add-to-list 'load-path "/usr/local/share/emacs/site-lisp")

Utilities

Reading a file as a string:

  (defun read-file (path)
    "Returns the contents of the file as a string"
    (with-temp-buffer
      (insert-file-contents path)
      (buffer-string)))

Opening a file as sudo:

  (defun sudo-find-file (file-name)
    "Like find file, but opens the file as root."
    (interactive "F")
    (let ((tramp-file-name (concat "/sudo::" (expand-file-name file-name))))
      (find-file tramp-file-name)))

Recursive assoc for nested alists:

  (defun assoc-recursive (alist &rest keys)
    "Recursively find KEYs in ALIST."
    (while keys
      (setq alist (cdr (assoc (pop keys) alist))))
    alist)

Format a millis timestamp into human-readable form:

  (defun format-epoch-millis (millis)
     (interactive "nTimestamp: ")
     (message (format-time-string "%F %r" (/ millis 1000))))

The same but for seconds:

  (defun format-epoch-seconds (seconds)
     (interactive "nTimestamp: ")
     (message (format-time-string "%F %r" seconds)))

Checking if a buffer contains a string:

  (defun buffer-contains-substring (string)
    (save-excursion
      (save-match-data
	(goto-char (point-min))
	(search-forward string nil t))))

Pretty-print JSON:

  (defun pprint-json (raw-json)
    (with-temp-buffer
      (insert raw-json)
      (json-pretty-print (point-min) (point-max))
      (buffer-substring (point-min) (point-max))))

Load environment variables into Emacs from a shell script:

  (cl-defun extract-vars-from-env-file (file &key dir)
    "Extracts an alist of variable name to value from
     a bash script that exports environment variables."
    (let ((file (expand-file-name file))
	  (var-re "\\(.+?\\)=\\(.+\\)$")
	  (env '()))
      (with-temp-buffer
	(cd (expand-file-name (or dir (file-name-directory file))))
	(insert (shell-command-to-string (concat "source "
						 (shell-quote-argument file)
						 " > /dev/null && env")))
	(goto-char (point-min))
	(save-match-data
	  (while (re-search-forward var-re nil t)
	    (push (cons (match-string 1) (match-string 2)) env))))
      env))

  (defun source-env-file (file)
    (interactive "fFile: \n")
    (let ((env (extract-vars-from-env-file file)))
      (dolist (binding env)
	(setenv (car binding) (cdr binding)))))

  (cl-defmacro with-env-from-file (file &rest body)
    (declare (indent 1))
    (let ((env-var (make-symbol "the-env"))
	  (path-var (make-symbol "the-path")))
      `(let* ((,env-var (extract-vars-from-env-file ,file))
	      (,path-var (assoc "PATH" ,env-var))
	      (exec-path
	       (if ,path-var
		   (append (split-string (cdr ,path-var) ":") exec-path)
		 exec-path))
	      (process-environment
	       (append
		(mapcar
		 (lambda (elt) (format "%s=%s" (car elt) (cdr elt)))
		 ,env-var)
		process-environment)))
	 ,@body)))

  (cl-defun call-with-env-from-file (file callback &key dir)
    (let* ((env (extract-vars-from-env-file file :dir dir))
	   (path (assoc "PATH" env))
	   (exec-path
	    (if path
		(append (split-string (cdr path) ":") exec-path)
	      exec-path))
	   (process-environment
	    (append (mapcar (lambda (elt) (format "%s=%s" (car elt) (cdr elt))) env)
		    process-environment)))
      (funcall callback)))

  (defmacro with-env (env &rest body)
    (declare (indent 1))
    `(let* ((process-environment
	     (append
	      (mapcar
	       (lambda (elt) (format "%s=%s" (car elt) (cdr elt)))
	       ,env)
	      process-environment)))
       ,@body))

Convenience macro to run some code in a particular default-directory:

  (defmacro with-default-directory (dir &rest body)
    (declare (indent 1))
    `(let ((default-directory ,dir))
       ,@body))
  (defun random-alnum (&optional n)
    (let* ((n-chars (or n 1))
	   (alnum "abcdefghijklmnopqrstuvwxyz0123456789")
	   (result ""))
      (dotimes (_ n-chars result)
	(let ((i (% (abs (random)) (length alnum))))
	  (setq result
		(concat result (substring alnum i (1+ i))))))))

A handy function to colorize a buffer with ANSI escape characters in it:

  (defun ansi-color (&optional begin end)
    (interactive)
    (let ((begin (or begin (point-min)))
	  (end (or end (point-max)))
	  (inhibit-read-only t))
      (ansi-color-apply-on-region begin end)))

Persisting variables between session

The idea behind this is pretty simple - variables get persisted in ~/.emacs.d/<persisted-vars-file> as a plist of (variable-name variable-value).

  (defvar persisted-vars-file "~/.emacs.d/persisted-vars")

This function retrieves the plist of persisted variables or nil if it doesn't exist:

  (defun get-persisted-plist ()
      (let ((file (expand-file-name persisted-vars-file)))
        (when (file-exists-p file)
          (let ((vars-plist-str (read-file file)))
            (unless (string= vars-plist-str "")
              (car (read-from-string vars-plist-str)))))))

This function retrieves a persisted variable:

  (defun get-persisted-var (var-name)
    "Retrieves the value of persisted variable `var-name`, or nil if not found"
    (let ((vars-plist (get-persisted-plist)))
      (when vars-plist
        (plist-get vars-plist var-name))))

And this function persists a variable:

    (defun persist-variable (var-name value)
      (let ((file (expand-file-name persisted-vars-file))
            (vars-plist (get-persisted-plist)))
        (if vars-plist
            (progn
              (plist-put vars-plist var-name value)
              (write-region
               (prin1-to-string vars-plist) nil file))
          (let ((vars-plist `(,var-name ,value)))
            (write-region
             (prin1-to-string vars-plist) nil file)))))

Process handling

Some utilities for calling out to other processes.

  (defun make-process-sentinel (success err)
    "Makes a process sentinel that calls `success` on success and `err` on error"
    (lambda (proc event)
      (cond ((string-match-p "finished" event) (funcall success))
	    (t (funcall err)))))

  (defun make-success-err-msg-sentinel (buf success-msg err-msg &optional kill-on-err)
    (make-process-sentinel
     (lambda ()
       (message success-msg)
       (kill-buffer buf))
     (lambda ()
       (message err-msg)
       (when kill-on-err
	 (kill-buffer buf)))))

A function to call a process passing some string as stdin and returning the process output:

  (defun make-process-fn (program &rest args)
    "Returns a function that, when called, call `program` with arguments `args`,
     passing the function argument as stdin"
    (lambda (&optional input)
      (with-temp-buffer
	(if input
	    (progn
	      (insert input)
	      (apply #'call-process-region (point-min) (point-max) program t t nil args))
	  (apply #'call-process program nil t nil args))
	(buffer-substring-no-properties (point-min) (point-max)))))

The same function but for commands that need to run in a shell:

  (defun make-shell-fn (program &rest args)
    "Returns a function that, when called, calls `program` in a shell
     with arguments `args`, passing the function argument as stdin"
    (lambda (&optional input)
      (let ((cmd (combine-and-quote-strings `(,program ,@args))))
	(with-temp-buffer
	 (if input
	     (progn
	       (insert input)
	       (call-shell-region (point-min) (point-max) cmd t t))
	   (call-process-shell-command cmd nil t))
	 (buffer-substring-no-properties (point-min) (point-max))))))

Running a shell command as sudo:

  (defun sudo-shell-command (command)
    (with-temp-buffer
      (cd "/sudo::/")
      (shell-command command)))

Buffer switch hooks

I want to be able to run code whenever I switch to a buffer running certain modes. The code to run is stored in a alist mapping mode names to lists of code to run (stored as a raw data structure to be eval'ed):

  (defvar buffer-mode-hooks '())

To add a new hook, push the code to run onto the correct list:

  (defun add-buffer-mode-hook (mode fn)
    (if-let ((existing-entry (assoc mode buffer-mode-hooks)))
	(push fn (cdr existing-entry))
      (let ((new-entry `(,mode . (,fn))))
	(push new-entry buffer-mode-hooks))))

Whenever the buffer changes, look up the major-mode to see if there is any code to run:

  (defun run-buffer-mode-hooks ()
    (when-let ((entry (assoc major-mode buffer-mode-hooks)))
      (dolist (fn (cdr entry))
	(funcall fn))))

  (add-hook 'buffer-list-update-hook #'run-buffer-mode-hooks)

Aliases

  (defalias 'doc 'describe-symbol)

Miscellaneous

  (setq warning-suppress-types
	'((undo discard-info)))

Init File

A function to reload my init file. It reloads the major mode after the init file is loaded to rebind keymappings.

  (defun reload-init-file ()
    (interactive)
    (load-file "~/.emacs.d/jdormit-init.el")
    (funcall major-mode))

And another one to edit it:

  (defun find-init-file ()
    (interactive)
    (find-file "~/.emacs.d/init.org"))

Keybindings

These are general keybindings; those specific to certain packages are in the sections for those packages.

In some modes I want vanilla Emacs bindings:

  (with-eval-after-load 'evil
    (add-to-list 'evil-emacs-state-modes 'benchmark-init/tabulated-mode)
    (add-to-list 'evil-emacs-state-modes 'benchmark-init/tree-mode)
    (add-to-list 'evil-emacs-state-modes 'cider-stacktrace-mode)
    (add-to-list 'evil-emacs-state-modes 'geiser-debug-mode)

Buffer commands

A function to switch to previous buffer from this blog post:

  (defun switch-to-previous-buffer ()
    "Switch to previously open buffer.
  Repeated invocations toggle between the two most recently open buffers."
    (interactive)
    (switch-to-buffer (other-buffer (current-buffer) 1)))

  (leader-def-key "TAB" 'switch-to-previous-buffer)

A function to kill all buffers except the current one from EmacsWiki:

  (defun kill-other-buffers ()
    "Kill all other buffers."
    (interactive)
    (mapc 'kill-buffer (delq (current-buffer) (buffer-list))))
  (jdormit/define-prefix "b" "buffer")
  (leader-def-key "bb" #'switch-to-buffer)
  (leader-def-key "bn" #'next-buffer)
  (leader-def-key "bp" #'previous-buffer)
  (leader-def-key "bd" #'kill-buffer)
  (leader-def-key "bm" #'kill-other-buffers)
  (leader-def-key "br" #'rename-buffer)

Frame commands

  (jdormit/define-prefix "F" "frame")
  (leader-def-key "Fn" #'make-frame-command)
  (leader-def-key "Fo" #'other-frame)
  (leader-def-key "Fm" #'delete-other-frames)
  (leader-def-key "Fd" #'delete-frame)

Running shell commands

  (leader-def-key "!" 'shell-command)
  (leader-def-key "|" 'shell-command-on-region)

Toggles

Like in Spacemacs, put all toggle commands behind a prefix:

  (jdormit/define-prefix "t" "toggle")

Toggles about line truncation:

  (leader-def-key "tt" 'toggle-truncate-lines)
  (leader-def-key "tT" 'visual-line-mode)
  (leader-def-key "tf" 'auto-fill-mode)

Toggle lisp debugging:

  (leader-def-key "td" 'toggle-debug-on-error)

Shells/REPLs

Emacs has a shell for every mood!

  (jdormit/define-prefix "s" "shells/REPLs")
  (leader-def-key "ss" 'shell)
  (leader-def-key "si" 'ielm)
  (leader-def-key "se" 'eshell)
  (leader-def-key "sa" 'ansi-term)

    :straight (:host github :repo "janpath/evil-numbers")
    :general
    ((normal visual motion) "g+" 'evil-numbers/inc-at-pt)
    ((normal visual motion) "g-" 'evil-numbers/dec-at-pt)
    ((normal visual motion) "g C-+" 'evil-numbers/inc-at-pt-incremental)
    ((normal visual motion) "g C--" 'evil-numbers/dec-at-pt-incremental))

Winner

Winner is a minor mode that keeps an undo/redo history of the window configuration:

  (winner-mode 1)
  (leader-def-key "wn" #'winner-redo)
  (leader-def-key "wp" #'winner-undo)

Buffer move

A handy package to shift buffers between open windows:

  (use-package buffer-move
    :general
    ("C-S-j" #'buf-move-down)
    ("C-S-k" #'buf-move-up)

xref

After I select an xref reference, I want the xref buffer closed:

  (defun xref-goto-xref-and-quit ()
    (interactive)
    (xref-goto-xref t))
  (general-def 'normal xref--xref-buffer-mode-map "RET"
    #'xref-goto-xref-and-quit :keymaps 'override)

Don't prompt for an identifier for these xref commands:

  (setq xref-prompt-for-identifier
	'(not xref-find-definitions
	      xref-find-definitions-other-window
	      xref-find-definitions-other-frame

Speedbar

Speedbar is cool but having it open in a separate frame is annoying. This makes it open in a side window in the same frame:

  (use-package sr-speedbar
    :commands (sr-speedbar-toggle
	       sr-speedbar-open
	       sr-speedbar-select-window
	       sr-speedbar-exist-p)
    :general
    (speedbar-mode-map "q" #'sr-speedbar-close))

  (defun switch-to-speedbar ()
    (interactive)
    (unless (sr-speedbar-exist-p)
      (sr-speedbar-open))
    (sr-speedbar-select-window))

  (leader-def-key "S" #'switch-to-speedbar)

Trailing whitespace

ws-butler deletes trailing whitespace on lines that you touch, but leaves other lines alone:

  (use-package ws-butler
    :straight (ws-butler :host github :repo "lewang/ws-butler")
    :hook ((prod-mode . ws-butler-mode)))

Whitespace Visualation

  (setq whitespace-line-column 80
	whitespace-style '(face lines-tail))
  (leader-def-key "tw" #'whitespace-mode)

Line Numbers

Toggle line numbers:

  (setq display-line-numbers-type 'visual)
  (leader-def-key "tn" 'display-line-numbers-mode)

Toggle line numbering mode (normal or relative):

  (defun toggle-line-number-mode ()
    (interactive)
    (when display-line-numbers
      (if (eq display-line-numbers 'visual)
	  (progn
	    (setq display-line-numbers t)
	    (setq display-line-numbers-type t))
	(progn
	  (setq display-line-numbers 'visual)
	  (setq display-line-numbers-type 'visual)))))

  (leader-def-key "tr" #'toggle-line-number-mode)

Display line numbers by default in code and org-mode buffers:

  (add-hook 'prog-mode-hook #'display-line-numbers-mode)
  (add-hook 'org-mode-hook #'display-line-numbers-mode)

Amx

A better M-x.

  (use-package amx
    :config
    (amx-mode))

Olivetti Mode

Olivetti is a minor mode for a nice writing environment.

  (use-package olivetti
    :config
    (setq-default olivetti-body-width 100)
    (setq olivetti-body-width 100)
    :commands olivetti-mode)

  (leader-def-key "to" 'olivetti-mode)

Winum

This package includes functions to switch windows by number.

  (defun winum-assign-0-to-dired-sidebar ()
    (when (equal major-mode 'dired-sidebar-mode) 10))

  (use-package winum
    :config
    (winum-mode)
    (add-to-list 'winum-assign-functions #'winum-assign-0-to-dired-sidebar)
    (leader-def-key "0" 'winum-select-window-0-or-10)
    (leader-def-key "1" 'winum-select-window-1)
    (leader-def-key "2" 'winum-select-window-2)
    (leader-def-key "3" 'winum-select-window-3)
    (leader-def-key "4" 'winum-select-window-4)
    (leader-def-key "5" 'winum-select-window-5)
    (leader-def-key "6" 'winum-select-window-6)
    (leader-def-key "7" 'winum-select-window-7)
    (leader-def-key "8" 'winum-select-window-8)
    (leader-def-key "9" 'winum-select-window-9))

I don't want which-key display "lambda" for the descriptions of these, so set a custom display function. This is stolen from Spacemacs.

  (push '(("\\(.*\\) 0" . "select-window-0") . ("\\1 0..9" . "window 0..9"))
        which-key-replacement-alist)
  (push '((nil . "select-window-[1-9]") . t) which-key-replacement-alist)

Backups and Autosaves

Store backups and autosaves in a centralized place. This should really be the default…

  (make-directory (expand-file-name "~/.emacs.d/autosaves") t)
  (setq auto-save-file-name-transforms '((".*" "~/.emacs.d/autosaves" t)))
  (setq backup-directory-alist '(("." . "~/.emacs.d/backups")))

Smartparens/Parinfer

Smartparens enables structured editing of s-expressions and other pairs:

  (use-package smartparens

Mode line

UI

Get rid of the janky buttons:

  (tool-bar-mode -1)

And the menu bar:

  (menu-bar-mode -1)

And the ugly scroll bars:

  (set-scroll-bar-mode nil)

Use variable-pitch-mode in text modes:

  (add-hook 'text-mode-hook (lambda () (variable-pitch-mode)))
  (add-hook 'w3m-mode-hook (lambda () (variable-pitch-mode)))

Always use buffer-face-mode in code and text buffers:

  (add-hook 'prog-mode-hook #'buffer-face-mode)
  (add-hook 'text-mode-hook #'buffer-face-mode)

Display the column number in programming modes:

  (add-hook 'prog-mode-hook #'column-number-mode)

Disable the bell:

  (setq ring-bell-function 'ignore)

Render stuff differently based on whether or not we are graphical:

  (defun graphical-setup ()
    (when (display-graphic-p (selected-frame))
      (message "Running graphically")))

  (defun non-graphical-setup ()
    (when (not (display-graphic-p (selected-frame)))
      (message "Running in terminal")
      (menu-bar-mode -1)))

  (defun do-graphical-non-graphical-setup ()
    (graphical-setup)
    (non-graphical-setup))

  (add-hook 'window-setup-hook #'do-graphical-non-graphical-setup)

Try to make the background normal colored in the terminal:

  (defvar no-background-in-tty-faces '(default line-number magit-section-highlight))

  (defun on-frame-open (frame)
    (unless (display-graphic-p frame)
      (menu-bar-mode -1)
      (dolist (face no-background-in-tty-faces)

      (dolist (face no-background-in-tty-faces)
	(set-face-background face "unspecified" (selected-frame)))))

  (add-hook 'window-setup-hook #'on-after-init)

Keybindings:

  (leader-def-key "Fw" 'jdormit/set-frame-width)
  (leader-def-key "Fh" 'jdormit/set-frame-height)
  (leader-def-key "Fs" 'jdormit/set-frame-size)

Transpose Frame

A handy utility that reverse the current frame window split (vertical to horizontal or vice-versa):

  (use-package transpose-frame
    :defer t
    :init
    (leader-def-key "wt" 'transpose-frame))

EShell

Easy keybinding to open EShell:

  (defun open-eshell (&optional arg)

    (if (and (fboundp 'projectile-project-root)
	     (projectile-project-root))
	(projectile-run-eshell arg)
      (eshell arg)))

  (leader-def-key "'" 'open-eshell)

Make EShell's tab completion work like Bash's:

  (setq eshell-cmpl-cycle-completions nil)

Add additional useful modules:

  (with-eval-after-load 'esh-module
    (add-to-list 'eshell-modules-list 'eshell-tramp))

  (with-eval-after-load 'eshell
    (require 'esh-module))

Prefer Lisp commands to external programs:

  (setq eshell-prefer-lisp-functions t
        eshell-prefer-lisp-variables t)

Enable password caching:

  (setq password-cache t
        password-cache-expiry 120)

Destroy shell buffers created by eshell when the process dies::

  (setq eshell-destroy-buffer-when-process-dies t)

Visual programs:

  (defun eshell-setup ()
    (add-to-list 'eshell-visual-commands "crawl")
    (add-to-list 'eshell-visual-commands "ssh")
    (add-to-list 'eshell-visual-subcommands '("kubectl" "exec"))
    (add-to-list 'eshell-visual-subcommands '("k" "exec")))

  (add-hook 'eshell-mode-hook #'eshell-setup)

And a function to run any program visually:

  (defun eshell/v (&rest args)
    (apply #'eshell-exec-visual args))

Load .dir-locals.el when switching directories:

  (add-hook 'eshell-mode-hook #'hack-dir-local-variables-non-file-buffer)
  (add-hook 'eshell-after-prompt-hook #'hack-dir-local-variables-non-file-buffer)

A function to properly clear the eshell:

  (defun clear-eshell (&optional prefix)
    (interactive)
    (let ((input (eshell-get-old-input)))
      (eshell/clear-scrollback)
      (eshell-emit-prompt)
      (insert input)))

  (add-hook 'eshell-mode-hook
   (lambda () (general-def eshell-mode-map "C-c C-o" #'clear-eshell)))

Some aliases:

  (defvar eshell-aliases nil
    "Aliases loaded when Eshell starts")

  (setq eshell-aliases
        '(("root" . "cd (projectile-project-root)")))

  (add-hook

Python

General

  (leader-def-key "sp" #'run-python)
  (add-hook 'python-mode-hook #'disable-tab-insert)

ISort is a Python utility to sort imports:

  (use-package py-isort
    :commands (py-isort-buffer py-isort-region)
    :config
    (setq py-isort-options '("-m=3"))
    :general
    (python-mode-map "C-c C-i" #'py-isort-buffer))

Run black on the current buffer:

  (general-def 'normal python-mode-map "C-M-\\" #'format-all-buffer)

sphinx-doc.el automatically generates doc strings for Python functions (and updates existing ones!):

  (use-package sphinx-doc
    :hook ((python-mode . sphinx-doc-mode)))

Dev environment/IDE stuff

Support pyvenv within Emacs:

  (use-package pyvenv
    :defer 0
    :commands (pyvenv-mode
               pyvenv-tracking-mode
               pyvenv-workon
               pyvenv-activate
               pyvenv-track-virtualenv)
    :config
    (pyvenv-mode)
    (pyvenv-tracking-mode))

  (defun eshell/workon (name)
    (pyvenv-workon name))

  (defun eshell/activate (dir)
    (pyvenv-activate dir))

  (defun eshell/deactivate ()
    (pyvenv-deactivate))

And support pyenv (NOT pyvenv) to change Python versions:

  (use-package pyenv-mode
    :defer t)

Use the LSP python client:

  (use-package lsp-python-ms
    :init
    (setq lsp-python-ms-auto-install-server t)
    (defun python-lsp ()
      (require 'lsp-python-ms)
      (lsp-deferred))
    :hook
    (python-mode . python-lsp)
    :general
    (python-mode-map "C-c C-d" #'lsp-describe-thing-at-point))

  (general-def 'normal python-mode-map "C-c C-d" #'lsp-describe-thing-at-point)

Override the flycheck python-mypy checker to run in the right directory:

  (flycheck-define-checker python-mypy
    "Mypy syntax and type checker.  Requires mypy>=0.580.

  See URL `http://mypy-lang.org/'."
    :command ("mypy"

                         (projectile-compilation-dir)))

Autoflake

Autoflake is a tool that removes unused imports and variables from Python code:

  (defvar autoflake-args '()
    "Arguments to pass to the autoflake command.

  See URL `https://pypi.org/project/autoflake' for options.")

  (defun autoflake (arg)
    (interactive "P")
    (let ((autoflake-cmd (or (executable-find "autoflake")
			     (error "Autoflake executable not found")))
	  (file (cond
		 ((or arg (not buffer-file-name))
		  (read-file-name "Run autoflake on file: "))
		 (buffer-file-name buffer-file-name)
		 (:else (error "Invalid file for autoflake")))))
      (apply #'call-process autoflake-cmd nil nil nil
	     (append autoflake-args (list "--in-place" file)))))

Testing

python-pytest.el integrates Pytest with Emacs:

  (use-package  python-pytest
    :commands (python-pytest-popup
	       python-pytest--current-defun)
    :general
    (python-mode-map "C-c t p" #'python-pytest-popup)
    ((normal motion visual) python-pytest-mode-map "g r" #'python-pytest-repeat)
    ((normal motion visual) python-pytest-mode-map "q" #'quit-window))

    (run-lisp (expand-file-name "~/.virtualenvs/hy/bin/hy")))

Go

Basic support:

  (use-package go-mode
    :mode (("\\.go\\'" . go-mode)))

LSP support - requires go-langserver.

  (add-hook 'go-mode-hook #'lsp-deferred)

Clojure

Start with clojure-mode:

  (use-package clojure-mode
    :mode (("\\.clj\\'" . clojure-mode)
           ("\\.cljs\\'" . clojurescript-mode)
           ("\\.cljc\\'" . clojurec-mode)

      (:= 3)
      (:+ 3)
      (match 1)
      (for-all 2)
      (checking 2)))

Add flycheck support:

  (use-package flycheck-clj-kondo
    :after (clojure-mode)
    :if (executable-find "clj-kondo")
    :ensure t)

Sprinkle in some CIDER:

Scheme

Tell emacs about file extensions which should activate scheme-mode:

  (add-to-list 'auto-mode-alist '("\\.guile\\'" . scheme-mode))
  (add-to-list 'auto-mode-alist '("\\.rkt\\'" . scheme-mode))

Geiser is a Scheme IDE for Emacs that supports a bunch of common Scheme implementations.

  (use-package geiser
    :commands (run-geiser)

    (setq geiser-active-implementations
          (cl-reduce (lambda (acc val)

                           (cons val acc)
                         acc))
                     '(guile racket chicken chez mit chibi gambit)
                     :initial-value nil))
    :general
    (geiser-mode-map 'normal

                     "M-," 'geiser-pop-symbol-stack)
    (geiser-debug-mode-map "SPC" leader-map))

And a handy shortcut to hop into a Geiser REPL:

  (leader-def-key "sg" 'run-geiser)

Common Lisp

SLIME is a set of modes and utilities for writing Common Lisp in Emacs. Quicklisp is the de-facto Common Lisp package manager. It comes with some Emacs bindings.

  (use-package php-mode
    :mode "\\.php\\'")

  (use-package mmm-mode
    :after php-mode)

Geben is an interface to XDebug allowing debugging PHP in Emacs:

  (use-package geben
    :commands (geben))

Some keybindings to start and end Geben:

  (general-def php-mode-map "C-c C-d" #'geben)
  (general-def php-mode-map "C-c C-q" #'geben-end)

An Eshell alias to start PHP using XDebug:

  (add-hook 'eshell-mode-hook
	    (lambda ()
	      (eshell/alias "php-debug"
			    "php -d xdebug.remote_enable=on -d xdebug.remote_host=127.0.0.1 -d xdebug.remote_port=9000 -d xdebug.remote_handler=dbgp -d xdebug.idekey=geben -d xdebug.remote_autostart=On $*")))

LSP for PHP requires php-language-server to be installed in ~/.composer:

  (add-hook 'php-mode-hook #'lsp-deferred)

YAML

  (use-package yaml-mode
    :mode ("//.yml//'"))

Pharen

Pharen is a Lisp that compiles to PHP. It looks a lot like Clojure.

  (add-to-list 'auto-mode-alist '("\\.phn\\'" . clojure-mode))

Bash

Use LSP if bash-language-server is installed.

  (when (executable-find "bash-language-server")
    (add-hook 'sh-mode-hook #'lsp-deferred))

Ruby

  (add-hook 'ruby-mode-hook #'lsp-deferred)

Rust

  (use-package rust-mode
    :mode "\\.rs\\'"
    :general
    (rust-mode-map "C-c <tab>" #'rust-format-buffer)
    :config
    (add-hook 'rust-mode-hook #'lsp-deferred))


  (use-package cargo
    :after (rust-mode)
    :config
    (add-hook 'rust-mode-hook #'cargo-minor-mode))

XML

Set up hideshow for nXML mode:

  (add-hook 'nxml-mode-hook #'hs-minor-mode)

  (add-to-list 'hs-special-modes-alist
	       '(nxml-mode
		 "<!--\\|<[^/>]*[^/]>" ;; regexp for start block
		 "-->\\|</[^/>]*[^/]>" ;; regexp for end block
		 "<!--"
		 nxml-forward-element
		 nil))

A function to format XML using tidy or xmllint if available, falling back to sgml-pretty-print:

  (defun xml-pretty-print ()
    (interactive)
    (let ((start (if (region-active-p) (region-beginning) (point-min)))
	  (end (if (region-active-p) (region-end) (point-max))))
      (cond
       ((executable-find "tidy")
	(shell-command-on-region start end "tidy -wrap 88 -q -i -xml" nil t))
       ((executable-find "xmllint")
	(shell-command-on-region start end "xmllint --format -" nil t))
       (t (sgml-pretty-print start end)))))

  (general-def nxml-mode-map "C-M-\\" #'xml-pretty-print)

CSVs

  (use-package csv-mode
    :mode "\\.csv\\'")

Markdown

  (use-package markdown-mode
    :commands (markdown-mode gfm-mode)
    :mode (("README\\.md\\'" . gfm-mode)
           ("\\.md\\'" . markdown-mode)
           ("\\.markdown\\'" . markdown-mode))
    :init (setq markdown-command "pandoc"))

Edit-indirect allows markdown-mode to edit source blocks in separate buffers:

  (use-package edit-indirect
    :defer t)

IELM

Enable lexical scoping in IELM:

  (add-hook 'ielm-mode-hook
            #'(lambda ()
                (interactive)
                (setq lexical-binding t)))

Ledger Mode

This mode requires that ledger be installed on the system.

  (use-package ledger-mode
    :mode "\\.ledger\\'"
    :config
    (add-to-list 'evil-emacs-state-modes 'ledger-report-mode)
    (general-def ledger-report-mode-map "SPC" leader-map)
    (add-hook 'ledger-mode-hook
	      (lambda ()
		(variable-pitch-mode 0)))
    (add-hook 'ledger-report-mode-hook
	      (lambda ()
		(variable-pitch-mode 0))))

Org mode links

First, keep a reference to filename of the .epub before nov.el blows it away:

  (defvar nov-epub-file)
  (add-hook 'nov-mode-hook
            #'(lambda ()
                (message "epub file: " buffer-file-name)
                (setq nov-epub-file buffer-file-name)))

That reference lets us construct a link back to the .epub:

  (defun org-epub-store-link ()
    (when (eq major-mode 'nov-mode)
      (let ((epub-name (alist-get 'title nov-metadata)))
        (org-store-link-props
         :type "file"
         :link (concat "file://" nov-epub-file)))))

  (add-hook 'org-store-link-functions 'org-epub-store-link)

Dashboard

Instead of the GNU Emacs buffer on startup, display a cool dashboard:

  (use-package dashboard
    :general
    (dashboard-mode-map "SPC" leader-map)
    :config
    (with-eval-after-load 'evil
      (add-to-list 'evil-emacs-state-modes 'dashboard-mode))
    (setq dashboard-items '((recents . 5)
			    (projects . 5))
	  dashboard-startup-banner 'official
	  dashboard-set-heading-icons t
	  dashboard-set-file-icons t
	  dashboard-set-navigator t))

  (dashboard-setup-startup-hook)

And hide some files from the recentf list:

  (with-eval-after-load 'recentf
    (setq recentf-exclude '(".*gcal.org"
                            #'backup-file-name-p)))

Email

I use mu/mu4e as my email client.

First, add it to the load path:

  (defvar mu4e-load-path)
  (setq mu4e-load-path
        (cond
         ((file-exists-p "/usr/local/share/emacs/site-lisp/mu/mu4e")
          "/usr/local/share/emacs/site-lisp/mu/mu4e")
         ((file-exists-p "/usr/share/emacs/site-lisp/mu4e")
          "/usr/share/emacs/site-lisp/mu4e")))
  (add-to-list 'load-path mu4e-load-path)

Then set up autoloads on the entry functions:

  (autoload 'mu4e (concat mu4e-load-path "/mu4e.el") nil t)
  (autoload 'mu4e-update-index (concat mu4e-load-path "/mu4e.el") nil t)

Then configure it:

  (with-eval-after-load 'mu4e
    (setq

Mu4e uses shr to render HTML emails. Unfortunately the shr function that sets faces in the rendered document has a bug: it appends the shr faces to the existing face-list, rather than prepending the shr face. This means that e.g. links don't actually get rendered correctly if there is some non-link face already on the text. The fix:

  (with-eval-after-load 'shr

Crontab

Magit ships with a cool utility called with-editor that lets you run a shell command using the current Emacs instance as $EDITOR. This means we can define a command to edit the crontab with the current Emacs instance:

  (defun edit-crontab ()
