Auto formatting for vi?

Question

Does an auto-formatting tool exist for vi that'll allow me to define per language preferences?

edit: I'm not looking for syntax highlighting. I'm looking for something that will apply formatting rules to my code. (Like brace positioning, spaces around oeprators, etc)

Answer 1

Well, there's Vim which comes with a lot of languages covered already and which is easy to customize per language.

Answer 2

Vim has tons of support for filetype-specific customisations. You might find what you are looking for in there.

Answer 3

You can add a file in ~/.vim/ftplugin/ for each file type. For example, set ~/.vim/ftplugin/c.vim to

set tabstop=2 shiftwidth=2

This sets your indentation for C files to two spaces.
