Emacs / Xemacs

C'est Kaspar (comprennent ceux qui le connaissent) qui m'a initié, en 1998, à cet éditeur irremplaçable, lorsque eclipse, quanta, nvu ou autre éditeur graphique ne suffit plus et en évitant le rupestre vim

The EmacsWiki is dedicated to documenting and discussing EmacsAndXEmacs and EmacsLisp. See the MissionStatement for more information.

AUCTeX is an extensible package for writing and formatting TeX files in GNU Emacs and XEmacs. It supports many different TeX macro packages, including AMS-TeX, LaTeX, Texinfo, ConTeXt, and docTeX (dtx files).

Emacs provides special major modes for editing files written in TeX and its related formats. TeX is a powerful text formatter written by Donald Knuth; like GNU Emacs, it is free software. LaTeX is a simplified input format for TeX, implemented using TeX macros. DocTeX is a special file format in which the LaTeX sources are written, combining sources with documentation. SliTeX is an obsolete special form of LaTeX.

Utile pour recharger un programme édité ailleurs (si on bosse avec plusieurs éditeurs simultanément sur un même fichier:

M-x revert-buffer (if you want you can bind it to a key), or use a more practice trick: use C-x C-v RET.

    Shift block of lines rigidly right or left (indent-rigidly). 

    Indent current line "appropriately" in a mode-dependent fashion. 
    Perform RET followed by TAB (newline-and-indent). 
    Merge two lines (delete-indentation). This would cancel out the effect of LFD. 
    Split line at point; text on the line after point becomes a new line indented to the same column that it now starts in (split-line). 
    Move (forward or back) to the first nonblank character on the current line (back-to-indentation). 
    Indent several lines to same column (indent-region). 

    Indent from point to the next prespecified tab stop column (tab-to-tab-stop). 
M-x indent-relative
    Indent from point to under an indentation point in the previous line.

Astuces / Tips

pour changer de thème, p. ex. pour avoir un fond sombre

 ALT-X customize-themes

<a href=\(.*\)>
<a class="ns" href=\1>

<a href="http://www.a">a</a>


<span class="ns">\1</span>

<font class="\(.*\)">\(.*\)<\/font>
<span class="\1">\2</span>

<font size=\(.*\)>\(.*\)<\/font>
<span class="\1">\2</span>
/* put here your variable list


note: you can get it with a command like
ex. your form has lines like

<input type="text" name="titre" size="60">
<input type="checkbox" name="image" value="1">

cat yourForm.php | sed 's|^.*name="||g' | sed 's|".*$||g'

will return

in emacs, do a:
CTRL-ALT-SHIFT-% (query-replace-regexp)
then try somes, if ok just make ! to change everything

the result

of course you can do the same with other replacement

eg you have

and want


this is the way:


\1   \1.\2@\3

use regular expression replacement:
type the string you want to replace, eg. ,
and it's done!

type the string you want to replace, eg. ,

WILL become
-> scratch, C-q + caract. (eg tab)
esc ^[
return ^M
linefeed ^J

for ubuntu:

sudo apt-get install php-mode php-elisp html-helper-mode css-mode

pour cakephp & ses fichus fichiers “views” *.ctp:

radeff@radeff-desktop:~$ gedit .xemacs/init.el

(add-to-list 'auto-mode-alist '(“\\.ctp$” . php-mode))

et relancer xemacs

  • Set up XEmacs so that it autodetects UTF-8 encoded files.
  • In the case of starting a new file in a non-UTF-8 locale, set the file coding system to UTF-8 using C-x RET f.
  • If running XEmacs in non-graphical mode in a UTF-8 xterm, set the terminal coding system to UTF-8 using C-x RET t.

If you want XEmacs to load UTF-8 files correctly, add the following lines to your ~/.xemacs/init.el:

(require 'un-define) (set-coding-priority-list '(utf-8)) (set-coding-category-system 'utf-8 'utf-8)

ci-dessus pas terrible, il faut mieux utiliser la solution suivante:


If you want XEmacs to load UTF-8 files correctly, add the following lines to your ~/.xemacs/init.el:

(require 'un-define)
(set-coding-priority-list '(utf-8))
(set-coding-category-system 'utf-8 'utf-8)
C-x esc esc
before commands: esc p
ESC < followed by C-x ESC ESC
esc <
esc >

Grâce au package TRAMP (Transparent Remote Access, Multiple Protocols), il est possible d’éditer des fichiers distants via SSH par exemple.

Installation (Debian) :

apt-get install tramp

Utilisation :

  • Avec xemacs :
    xemacs /[ssh/user@host]/chemin/fichier
  • Avec emacs :
    emacs /ssh:user@host:/chemin/fichier

Remarque :

Ajoutez (setq tramp-default-method “ssh”) dans votre ~/.xemacs/custom.el pour de pas avoir à préciser la méthode ssh
