How do I tidy up an HTML file's indentation in VI?

Question

How do I fix the indentation of his huge html files which was all messed up?

I tried the usual \"gg=G command, which is what I use to fix the indentation of code fil

Answer 1

As tylerl explains above, set the following:

:filetype indent on
:set filetype=html
:set smartindent

However, note that in vim 7.4 the HTML tags html, head, body, and some others are not indented by default. This makes sense, as nearly all content in an HTML file falls under those tags. If you really want to, you can get those tags to be indented like so:

:let g:html_indent_inctags = "html,body,head,tbody" 

See "HTML indenting not working in compiled Vim 7.4, any ideas?" and "alternative html indent script" for more information.
