How to remove :hover styles from your stylesheets without messing up complex, useful rules like: .ok, .not-ok:hover, .also-ok { ... } FYI relies on UnderscoreJS to user _.reject(), but that's clearly a writable function

gistfile1.coffee

if 'createTouch' of document
  ignore = /:hover\b/
  try
    for stylesheet in document.styleSheets
      idxsToDelete = []
      # detect hover rules
      for rule, idx in stylesheet.cssRules
        if rule.type is CSSRule.STYLE_RULE and ignore.test(rule.selectorText)
          newSelector = _.reject rule.selectorText.split(","), (s) -> ignore.test s
          if newSelector.length > 0
            newRule = newSelector.join(",").concat rule.cssText.substr(rule.cssText.indexOf("{"))
            stylesheet.deleteRule idx
            stylesheet.insertRule newRule, idx
          else
            idxsToDelete.unshift idx
      # delete hover rules
      stylesheet.deleteRule idx for idx in idxsToDelete
