(back to ProgrammingNotes)
Emacs is more than an editor - it's a lifestyle. I spent years using vi but have fairly recently started to make the investment to join the cult. I prefer emacs to IDE's because I feel that the investment in time that I spend learning it will be more likely to pay off because emacs has been around for a long time and will continue to be around for a long time. Also, more of the smartest people I've worked with have used emacs than all other development environments combined (although lately Eclipse is gaining).
Packages - here's a great idea; a package manager for emacs (like cpan for perl):
http://tromey.com/elpa/
C style - p.322
M-x c-set-style
GNU|K&R|BSD|Stroustrup|Whitesmith|Ellemtel
Vovida code appears to use
Stroustrup
.
Tabs - to replace tabs with spaces mark a region then
M-x untabify
(
M-x tabify
goes the other way). Useful variables related to tabs are
-
indent-tabs-mode
- t
for spaces, nil
for tabs
-
tab-width
- number of spaces per tab
-
c-tab-always-indent
- if t
, will always indent a line of code. if nil
, will indent only if you hit the tab key at the beginning of the line.
You can embed these commands in a comment on the first line of a file. Let's say you want to interact with files created by people using Eclipse with its completely retarded default config of hard 4-character tabs. Just make sure that this text is somewhere on the first line of the file, either inside a
/* ... */
or after a
//
:
-*- indent-tabs-mode: t; tab-width: 4 -*-
Ant - to use ant instead of make to compile programs inside emacs, you'll want to run ant with the
-emacs
flag which makes the output more plain but allows emacs to find error messages. The easy way to do this is to add
(custom-set-variables '(compile-command "ant -emacs"))
to your .emacs file.
Compiling -
M-x compile
, then
C-x `
(i.e. back-tick) to go to the next error.
Code Browsing -
http://ecb.sourceforge.net/ I haven't played with this package yet but it looks good
Java - a good integrated development environment for Java is JDEE at
http://jdee.sourceforge.net/. It's not that easy to install (it has lots of dependencies).
SQL - yes, there's a mode for editing SQL queries:

DOS - If you have to edit DOS files (which is likely if you program for a living
![wink wink](http://caboteria.org/wiki/pub/TWiki/SmiliesPlugin/wink.gif)
) then Emacs works very well indeed. You can use it to translate into DOS or Unix format :
C-x RET f unix RET
or
C-x RET f dos RET
(don't forget to save the file after you do). For more info see the
manual.
XSLT -

Mac - there are a few places to get emacs for the mac:
Windows - you can use cygwin's bash as a shell within emacs by putting
c:\cygwin\bin
in your windows path before running emacs.
