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

LaTeX
auctex
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).

TeX-Mode
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.

indentation
C-x TAB
Shift block of lines rigidly right or left (indent-rigidly).
TAB
Indent current line "appropriately" in a mode-dependent fashion.
LFD
Perform RET followed by TAB (newline-and-indent).
M-^
Merge two lines (delete-indentation). This would cancel out the effect of LFD.
C-M-o
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).
M-m
Move (forward or back) to the first nonblank character on the current line (back-to-indentation).
C-M-\
Indent several lines to same column (indent-region).
M-i
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.

Replacing with RegExp within (x)emacs
query-replace-regexp <a href=\(.*\)> <a class="ns" href=\1> <a href="http://www.a">a</a> b c <\(/?\)font> <font>\(.*\)<\/font> \1 <font.*>\(.*\)<\/font> <span class="ns">\1</span> <font class="\(.*\)">\(.*\)<\/font> <span class="\1">\2</span> <font size=\(.*\)>\(.*\)<\/font> <span class="\1">\2</span>
pour changer les noms de variables php
/* put here your variable list var1 variabl2 etc... 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 titre image */ /*copy-paste var1 variabl2 etc... */ in emacs, do a: CTRL-ALT-SHIFT-% (query-replace-regexp) ^\(.*\)$ [ENTER] $\1=$_POST['\1']; [ENTER] then try somes, if ok just make ! to change everything the result $var1=$_POST['var1']; $variabl2=$_POST['variabl2']; of course you can do the same with other replacement
Replacing emails with firstname emails
eg you have
John.Doe@soviet.org Mary.Smith@bolchoi.net
and want
John John.Doe@soviet.org Mary Mary.Smith@bolchoi.net
this is the way:
CTRL-SHIFT-ALT-%
^\([A-Z][a-z]*\)\.\([A-Z][a-z]*\)@\(.*\)$ \1 \1.\2@\3
how to introduce a new line with regexp (x)emacs
example: transform a,b,c into a b c use regular expression replacement: alt-ctrl-shift-% type the string you want to replace, eg. , RET alt-J RET ! and it's done! THE OTHER WAY (REPLACE LINES WITH STHING) alt-ctrl-shift-% type the string you want to replace, eg. , alt-J RET THEN THE REPLACEMENT, eg , RET ! a b c WILL become a,b,c
how to print special characters
-> scratch, C-q + caract. (eg tab) esc ^[ return ^M linefeed ^J

How can I get XEmacs to work with UTF-8 files?
- 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:

FTP / SFTP / Tramp
Source: http://www.benjaminbaudouin.com/xemacs-edit-over-ssh (dead link)
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
