Editor Emacs
From Apache OpenOffice Wiki
This page is about (X)Emacs, editor and kitchen sink, and the only real one, for that matter.
Emacs and Cscope
Emacs has a premade file for cscope, generally packaged with cscope. So adding
;;cscope integration (require 'xcscope)
(to your .emacs, normally) is enough to activate it. Major shortcut are :
- Find-symbol : C-c s s
- Find-global-definition : C-c s g
- Next-symbol : C-c s n

Useful Keyboard Macros
Here is a macro for inserting include-guards for auto-generated UNO headers. If you typed
#include <com/sun/star/module/XInterfaceName.hpp>
you can call the following keyboard macro:
(fset 'bm-make-default-ifndef [home ?\C-s ?< ?\C- ?\C-s ?> left ?\M-w home ?\C-m up ?# ?i ?f ?n ?d ?e ?f ? ?_ ?\C-y ?_ ?\C- home C-right right ?\M-x ?r ?e ?p ?l ?a ?c ?e ?- ?s ?t ?r ?i ?n ?g ?\C-m ?/ ?\C-m ?_ ?\C-m end ?\C- home C-right right ?\C-x ?\C-u end ?\C- home C-right right ?\M-x ?r ?e ?p ?l ?a ?c ?e ?- ?s ?t ?r ?i ?n ?g ?\C-m ?. ?\C-m ?_ ?\C-m home down end ?\C-m ?# ?e ?n ?d ?i ?f home up])
to get the following:
#ifndef _COM_SUN_STAR_MODULE_XINTERFACENAME_HPP_ #include <com/sun/star/module/XInterfaceName.hpp> #endif
C++ Mode for OOo Development
This is what I (bm) use for developing OOo sources in Emacs. The only thing that bothers me from time to time is that when having large templates, the indentation is not very good. I have not found a solution for that.

Keywords for Syntax Highlighting
What is also useful are some keywords that can be used for syntax-highlighting (font-locking).

Some font definitions for additional Keywords
In the above section there are some faces used, that are not part of the default set of font-locking faces. The definitions are here. You can customize them, of course, if you do not like the colors.
