Hi Grace,
The Emacs Lisp package, cc-mode, handles the indenting of code coded in any
of the C family of languages, including Java. cc-mode uses spaces to indent
code, although this is not obvious as cc-mode binds the TAB key to an
indent command. Thus, when you type the TAB key, you are invoking this
command, which inserts spaces into the current line, with the number of
spaces being determined by the syntactic element at the current cursor
position and by the current indentation style. You can customize just about
every aspect of cc-mode, including what indentation style is used, whether
spaces or tabs are inserted, etc.
The JDE sets up cc-mode to do standard Java indentation, using cc-mode's
defaults for indentation character (SPACE) and Java indentation style. You
don't have to do anything in your .emacs file to get default Java
indentation. If you want to customize any aspect of indentation, you should
read the cc-mode info file and follow the instructions there. Any
customization code should be put in a jde-mode hook function defined in
your .emacs file. See the JDE FAQ at the JDE website for more information.
If you have specific questions, please feel free to post them to me or the
JDE mailing list.
I am copying my reply to the JDE mailing list in case someone more
knowledgable than I about indentation may have something to add to or
correct in what I have said.
Good luck,
Paul
