wrap_line_length
Type: Number
Default value: 0 (disabled)
Maximum characters per line. 0 disables, max is 250.

unformatted
Type: String|Array

Attention: Make sure you play around with the settings and view the HTML in the browser. Pay special attention to whitespace around links and other inline elements, such as <strong> and <span>. If you specify a list of elements to remain unformatted, you will definitely need to make sure that whitepace is rendering the way you want it to.

Custom Options
You can also specify the options in the Gruntfile if you wish, like this:
prettify: options: indent: 2 indent_char: ' ' wrap_line_length: 78 brace_style: 'expand' unformatted: 'a' 'sub' 'sup' 'b' 'i' 'u' ...Example configurations for prettifying one file at a time, or entire directories of files:
prettify: options: config: '.prettifyrc' // Prettify a directory of files all: expand: true cwd: 'test/actual/ugly/' ext: '.html' src: '*.html' dest: 'test/actual/pretty/' // Or prettify one file at a time using the "files object" format files: 'pretty/index.html': 'ugly/index.html' // Or the "compact" src-dest format one: src: 'test/actual/ugly/index.html' dest: 'test/actual/pretty/index.html' See the [grunt][] docs for more information about task configuration.
