See `uglifyjs --acorn` in the docs.  `acorn` can also produce mozilla AST which can be fed into uglify via:\r\n\r\n    acorn test.js | uglifyjs --spidermonkey\r\n\r\nBe aware that the version of acorn specified in uglify's package.json is out of date. A standalone acorn is probably the way to go.\r\n\r\nBut in the end, this syntax stuff is not a pre-requisite for this newline/linefeed issue. Just something you may want to keep in mind for future standards compliance work... or not."}}
