Acerca de este documento

Este documento está hecho en org-mode y es tanto mi configuración de emacs como la explicación de esta. Más información sobre esto aquí.

Mi idea es que termine siendo más o menos un tutorial de emacs, tal vez extendido con los articulos del blog. A ver como sale. Se puede instalar mi configuración de emacs del siguiente modo:

git clone https://daemons.it/cgit/dotfiles
cd dotfiles
./instala.sh emacs

Que hace esto exactamente? Básicamente, instalar todos los paquetes y scripts mencionados en este documento. De un modo más extendido, lo que hace el script de instala.sh es esto (la explicación en los comentarios):

# Establece el directorio de las configuraciones, lo crea y las copia ahí
EMACSDIR="$HOME/.emacs.d"
mkdir -p $EMACSDIR
ln -sf $(pwd)/emacs.d/{init.el,init-literate.org} $EMACSDIR

# crear private-literate.org si no existe para que no se queje init.el
if [[ ! -e $EMACSDIR/private-literate.org ]]
then
    echo -e "* Vacio\n#+BEGIN_SRC lisp\n#+END_SRC" > $EMACSDIR/private-literate.org
fi

# Instalar todos los paquetes de emacs
emacs -Q --batch --eval "(load-file \""$EMACSDIR/"init.el\")"
emacs -Q --batch --eval "(load-file \""$EMACSDIR/"init-literate.el\")"
emacs -Q --batch --eval "(load-file \"/tmp/powerline.el\"))"

# Por algún motivo al compilar desde el-get mete una ruta incorrecta en org-loaddefs.el
sed -i "s,org-mode-maint/lisp/,,g" $EMACSDIR/el-get/org-mode-maint/lisp/org-loaddefs.el

# Necesito permiso de superusuario para copiar los scripts capture y demacs en /usr/local/bin/
sudo ln -sf $(pwd)/emacs.d/{capture,demacs} /usr/local/bin/

Configuración Genérica

En esta sección se tocará la configuración que tenga que ver con el manejo general de emacs. Yo suelo arrancar emacs usando un script que llamo demacs. En el llamo a emacs en modo demonio para que quede corriendo en segundo plano y luego abro emacsclient. Que ventajas tiene esto? Si por lo que sea petan las X, emacs sigue corriendo, por ejemplo. O que puedo no tener ninguna ventana de emacs abierta y aún así no perder las ventanas que hay en ellas. O mejor aún, que puedo usarlo desde terminal como editor de mutt.

El script que uso es el siguiente:

#!/bin/bash

USERID=`id -u`
if [[ ! -e /tmp/emacs$USERID/server ]]
then
    emacs --daemon
    emacsclient -c -n -e '(load-file "/tmp/powerline.el")' -e "(org-agenda-list)"
else
    emacsclient -c -n -e "(org-agenda-list)"
fi

Me gusta que nada más abrirlo, me muestre la agenda, por eso está el (org-agenda-list). El load-file al fichero del powerline es debido a que emacs al lanzarse en modo demonio, es como si se lanzase en modo terminal, por lo que hay ciertos paquetes que los carga como tal. Y dado que el powerline que uso es un poco especialito, si no se arranca desde la gui, se ve feo. Por ello la primera vez que se ejecute el emacsclient, evalua el powerline.

Iniciar paquetes elpa/melpa/marmalade

Ahora mismo el repositorio de marmalade está comentado por que da un error al usarlo con https. Uso el de ojab.ru, que es un proxy a marmalade.

(setq package-archives '(("gnu" . "https://elpa.gnu.org/packages/")
                         ;;("marmalade" . "https://marmalade-repo.org/packages/")
                         ("marmalade" . "https://ojab.ru/marmalade/")
                         ("melpa" . "https://melpa.org/packages/")))
(package-initialize)

Actualizar paquetes

(package-refresh-contents)

Asegurarse de que use-package y el-get estan instalados y los inicializa

;; Comprueba si use-package está instalado, sinó lo instala desde los repositorios
(unless (require 'use-package nil 'noerror)
  (package-install 'use-package))

(require 'use-package)

;; Añade la ruta de el-get
(add-to-list 'load-path (concat user-emacs-directory "el-get/el-get/"))

;; Comprueba si el-get está instalado, sinó lo instala desde un gist
(unless (require 'el-get nil 'noerror)
  ;; comprobar si existe el fichero a descargar, si existe no lo descarga
  (if (not (file-exists-p "/tmp/el-get-install.el"))
      (url-copy-file "https://raw.githubusercontent.com/dimitri/el-get/master/el-get-install.el" "/tmp/el-get-install.el"))
  (load-file "/tmp/el-get-install.el"))

(use-package el-get)
Hábitos
(use-package org-habit
  :init
  (add-to-list 'org-modules 'org-habit)
    :config
    (setq org-habit-preceding-days 7
          org-habit-following-days 0
          org-habit-graph-column 50
          org-habit-show-habits-only-for-today t
          org-habit-show-all-today t))

Moverse por el buffer

Subir y bajar párrafos:

(global-set-key "\M-p" 'backward-paragraph)
(global-set-key "\M-n" 'forward-paragraph)

Establecer nombre y correo

Al exportar en org-mode, por ejemplo, coge estos valores.

(setq user-full-name "drymer"
      user-mail-address "drymer [ EN ] autistici.org")

Abrir cómo buffer inicial

(setq initial-buffer-choice "~/Documentos/org/index.org")

Iniciar cómo servidor

De este modo puedo usar emacsclient desde la terminal y la sesión de emacs existente.

(server-start)

Destacar el par coincidente

(show-paren-mode)

Auto-guardado

Es bastante molesto que te vaya dejando la mierda por ahí, mejor en un directorio conjunto.

(defvar backup-dir (expand-file-name (concat user-emacs-directory "backup/")))

(setq backup-directory-alist (list (cons ".*" backup-dir)))
(setq auto-save-list-file-prefix autosave-dir)
(setq auto-save-file-name-transforms `((".*" ,autosave-dir t)))
(setq tramp-backup-directory-alist backup-directory-alist)
(setq tramp-auto-save-directory autosave-dir)

Modo por defecto

Al abrir un archivo o bufer sin algún modo asociado, se abrirá en modo texto.

(setq major-mode 'text-mode)

Acepta 'y' o 'n' cuando pide 'yes' o 'no'

(fset 'yes-or-no-p 'y-or-n-p)

Lenguaje por defecto en emacs y org-mode

(setq current-language-environment "Spanish")
(setq org-export-default-language "es")

Moverse por ventanas con shift

No funciona en org-mode.

Formato de las columnas de númeracion

Por defecto no se activan, hay que hacerlo a mano con M-x linum-mode.

  (setq linum-format "%4d \u2502 ")

Ventana limpia

Sin scroll bar, menu bar ni tool bar.

  (tool-bar-mode -1)
  (scroll-bar-mode -1)
  (menu-bar-mode -1)

UTF-8

  (prefer-coding-system       'utf-8)
  (set-default-coding-systems 'utf-8)
  (set-terminal-coding-system 'utf-8)
  (set-keyboard-coding-system 'utf-8)
  (setq x-select-request-type '(UTF8_STRING COMPOUND_TEXT TEXT STRING))

Tipo de fuente

  (custom-set-faces '(default ((t (:family "DejaVu Sans Mono" :foundry "unknown" :slant normal :weight normal :height 107 :width normal)))))

Partir buffers de manera más bonita

(add-to-list 'default-frame-alist '(height . 40))
(add-to-list 'default-frame-alist '(width . 90))

Scroll

Similar a la manera de vim. No tengo claro en que se diferencia, pero me gusta cómo funciona.

  (setq scroll-step            1
      scroll-conservatively  10000)

  (setq scroll-margin 80
      scroll-conservatively 3000
      scroll-up-aggressively 0.02
      scroll-down-aggressively 0.02)

Configuración por modos o lenguajes

JSON

Los archivos cuyo nombre termine por los mencionados abajo, usarán json-mode.

  (use-package json-mode
       :mode "\\.json\\'"
       :ensure t)

Haskel

Lo usé un tiempo para xmonad, pero ya no está activo.

     (use-package haskell-mode
       :config
       (add-hook 'haskell-mode-hook 'turn-on-haskell-doc-mode)
       (add-hook 'haskell-mode-hook 'turn-on-haskell-indentation)
       (add-hook 'haskell-mode-hook 'haskell-font-lock-symbols t)
       (put 'downcase-region 'disabled nil)
       :ensure t
       )

Markdown

Cargar markdown-mode, usar utf-8 al exportar y asociar el modo a las extensiones ".md" y ".markdown".

  (use-package markdown-mode
    :init
    (setq markdown-xhtml-header-content "<meta http-equiv='Content-Type' content='text/html; charset=utf-8' />")
    :mode "\\.md\\'"
    :ensure t
    )

Python

La configuración de elpy:

(if (not (el-get-package-installed-p 'elpy))
    (el-get 'sync 'elpy))

(use-package elpy
  :init
  (setq elpy-modules '(elpy-module-sane-defaults elpy-module-company elpy-module-eldoc elpy-module-pyvenv))
  (add-hook 'python-mode-hook 'flycheck-mode)
  (setq elpy-rpc-backend "jedi")
  :config
  (add-to-list 'ivy-completing-read-handlers-alist '(elpy-doc . completing-read-default)) ;; véase https://github.com/abo-abo/swiper/issues/892
  (elpy-enable))

Este paquete muestra una ralla que marca los 79 carácteres, para cumplir con el pep8.

  (use-package fill-column-indicator
    :init
    (setq fci-rule-color "purple")
    (setq fci-rule-column 79)
    (add-hook 'python-mode-hook 'fci-mode)
    :ensure t
    )

Corrección con flycheck, mejor que flymake:

  (use-package flycheck
    :config
    (setq flycheck-global-modes '(python-mode))
    (global-flycheck-mode)
    :diminish flycheck-mode
    :ensure t
    )

Configura virtualenvwrapper para eshell, lo que habilita la orden workon y demás.

  (use-package virtualenvwrapper
    :init
    (setq venv-location "~/.virtualenvs/")
    (venv-initialize-eshell)
    :ensure t
  )

web-mode

No lo he mirado mucho ya que apenas lo uso, es un copia-pega.

  (defun my-setup-php ()
    (web-mode)
    (make-local-variable 'web-mode-code-indent-offset)
    (make-local-variable 'web-mode-markup-indent-offset)

    (setq web-mode-code-indent-offset 4)
    (setq web-mode-css-indent-offset 2)
    (setq web-mode-markup-indent-offset 2))

  (add-to-list 'auto-mode-alist '("\\.php$" . my-setup-php))

  (setq web-mode-ac-sources-alist
        '(("css" . (ac-source-words-in-buffer ac-source-css-property))

                              ac-source-dictionary))))

  (add-to-list 'auto-mode-alist '("\\.php$" . my-setup-php))

DockerFile

Editar archivos DockerFile.

  (use-package dockerfile-mode
    :mode "Dockerfile\\'"
    :ensure t)

kivy-mode

Si el paquete no está instalado, lo instala mediante el-get.

  (use-package kivy-mode
    :mode "\\.kv\\'"
    :ensure t
  )

gnu-social-mode

  • Definir archivo de notas para org-capture
      (setq org-default-notes-file "~/Documentos/org/notas.org")
    
  • Estados de los objetos de las listas

    Todas las secuencias anteriores al símbolo | son tareas que no se consideran terminadas, al contrario de las que estan después de este.

    Los estados que tienen el símbolo @ son los que, al escogerlos, abren un buffer preguntando si se quiere añadir alguna nota respecto al cambio de estado. Las que tienen el símbolo !, en cambio, crean una estampa de tiempo, para dejar constancia de cuando se ha cambiado a ese estado.

      (setq org-todo-keywords
            '((sequence "TODO(t)" "NEXT(n)" "IN-PROGRESS(p@/!)" "WAITING(w@/!)" "|" "DONE(d!)" "CANCELED(c@)")))
    
  • Refile

    Mover un arbol debajo de otro del mismo fichero o de los archivos de las agendas.

      (setq org-refile-targets '((nil :maxlevel . 10) (org-agenda-files . (:maxlevel . 4))))
    
  • Caldav

    Lo tengo funcionando con owncloud. Si no está instalado, lo instala con el-get. Esta parte no es real, como son cosas "sensibles", van en un fichero a parte. Pero seria algo así:

      (unless (require 'org-caldav nil 'noerror)
        (el-get-install 'org-caldav))
    
      (use-package org-caldav
        :init
        (setq org-caldav-url "http://caldav.ejemplo/")
        (setq org-caldav-calendar-id "org")
        (setq org-caldav-files '("~/Documentos/org/index.org" "~/Documentos/org/index.org_archive" "~/Documentos/org/notas.org"))
        (setq org-caldav-inbox '(id "c14f-42fe-a358-648240e73991"))
        (setq org-caldav-save-directory "~/Documentos/org/")
        )
    

    Esto es un workaround para un bug raro de url-cookie:

  • Configuración del calendario
      (setq org-icalendar-timezone "Europe/Madrid")
    
  • calfw

    Paquete para ver las tareas de org-mode en un formato de calendario más típico. Los arrays son sólo traducciones. Si el paquete no está instalado, lo instala mediante el-get.

  • Tareas repetitivas

    Las tareas marcadas para repetirse, al marcarlas cómo DONE vuelven al estado TODO y añade un timestamp del dia y la hora.

      (setq org-log-repeat 'time)
    
  • Cambiar el formato de CLOCKTABLE

    Por defecto, al pasar de las 24 horas dedicadas, lo mostrará cómo 1d. Con el siguiente snippet, seguirá mostrando horas.

      (setq org-time-clocksum-format
            '(:hours "%d" :require-hours t :minutes ":%02d" :require-minutes t))
    
  • Quitar tags de la agenda
    (setq org-agenda-remove-tags t)
    
Edición, diseño y varios
  • Atajos de teclado

  • Configuracion de bloques de código

    La primera linea formatea el código cómo si se tratase de código nativo, la segunda indenta acorde al código.

      (setq org-src-fontify-natively t)
      (setq org-src-tab-acts-natively t)
      (setq org-src-preserve-indentation t)
      (setq org-edit-src-content-indentation 0)
    
  • Elementos de marcado

    La primera línea esconde los símbolos y aplica el marcado, y la segunda cambia el color a los elementos de marcado que empiezan por =.

Añadir soporte para editar archivos en docker

Usar del siguiente modo: /docker:drunk_bardeen:/etc/passwd. Sacado de la wiki de emacs. Se puede usar el siguiente alias en bash para ver el nombre del container en ejecución:

alias dname="docker ps | perl -we 'use strict; $_ = <>; m/^(.*)NAMES/ or die; my $offset = length($1); while(<>) {substr($_, 0, $offset, q()); chomp; for(split m/\\W+/) {print qq($_:\n)} }'"

Desactivado de momento, no tengo docker en este pc.

(push
 (cons
  "docker"
  '((tramp-login-program "docker")
    (tramp-login-args (("exec" "-it") ("%h") ("/bin/bash")))
    (tramp-remote-shell "/bin/sh")
    (tramp-remote-shell-args ("-i") ("-c"))))
 tramp-methods)

  "(tramp-completion-handle-file-name-all-completions \"\" \"/docker:\" returns
