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

    The main problem using the smart indentation is that if the XML (or HTML) sits on one line as it may end up coming back from a curl request then gg=G won't do the trick. Instead I have just experienced a good indentation using tidy directly called from VI:

    :!tidy -mi -xml -wrap 0 %

    This basically tells VI to call tidy to cleanup an XML file not wrapping the lines to make them fit on the default 68 characters wide lines. I processed a large 29MB XML file and it took 5 or 6 seconds. I guess for an HTML file the command should therefore be:

    :!tidy -mi -html -wrap 0 %

    As mentioned in comments, tidy is a basic tool which you could find on many base Linux / MacOS systems. Here is the projet's page in case you wish you had it but don't: HTML Tidy.

    I use this script: https://github.com/maksimr/vim-jsbeautify

    In the above link you have all the info:

    1. Install
    2. Configure (copy from the first example)
    3. Run :call HtmlBeautify()

    Does the job beautifully!

    Have you tried using the HTML indentation script on the Vim site?

    You can integrate both tidy and html-beautify automatically by installing the plugin vim-autoformat. After that, you can execute whichever formatter is installed with a single keystroke.

    With filetype indent on inside my .vimrc, Vim indents HTML files quite nicely.

    Simple example with a shiftwidth of 2:

    <html>
  <body>
    <p>
    text
    </p>
  </body>
</html>

    There's several things that all need to be in place. Just to summarize them all in one location:

    Set the following option:

    :filetype indent on
:set filetype=html           # abbrev -  :set ft=html
:set smartindent             # abbrev -  :set si

    Then either move the cursor to the top of the file and indent to the end: gg =G
    Or select the desired text to indent and hit = to indent it.
