CSS compiler using the AST provided by css-parse.

css-stringify exports a single function which dumps CSS AST:

var stringify = require('css-stringify');
var parse = require('css-parse');

var ast = parse('body { font-size: 12px; }');

var str = stringify(ast);

To get compressed output pass compress option:

var compressed = stringify(ast, {compress: true});

To get a source map pass sourcemap option:

var ast = parse('body { font-size: 12px; }', {position: true});
var result = stringify(ast, {sourcemap: true});

result.code // string with CSS
result.map // source map

Note that the AST should contain position information (position option of css-parse set to true).

Formats 15,000 lines of CSS (2mb) in 23ms on my macbook air.
