Post-render function for curly quotes

  Cool, I was just wondering about the ease of incorporating something like this. A couple of questions:
  
  1) How do you use this? Is postrender a built-in object whose methods are each called every time a passage is rendered?
  2) Is this code compatible with SugarCube?
  
  Thanks!

  You can include this code in any passage tagged as "script".
  I'd call "postrender" a collection of functions rather than methods, as there is no "this" object, but it does work as you describe.

  Yes, if you have a recent version of SugarCube (-2835 or later). In fact, I only tested it with SugarCube, but it should work with the vanilla headers as well.

  Great to know! I'll give it a try in the near future and let you know how it goes.

  I fixed a bug in the earlier code: when there is a double quoted string surrounded by white space, the white space was discarded. This problem is fixed in the new version:

  
postrender.quotes = function(passage, content, task) {
function processTextNodes(node) {
if (node.nodeType == 3) { // text node
node.nodeValue = node.nodeValue
.replace(/\b'/g, '’')
.replace(/'\b/g, '‘')
.replace(/"(\s|$)/g, '”$1')
.replace(/(\s|^)"/g, '$1“');
} else {
for (var i in node.childNodes) {
processTextNodes(node.childNodes[i]);
}
}
}
processTextNodes(passage);
}

  In recent SugarCube releases the replacement with HTML entities no longer works, so I made a new version which uses JavaScript Unicode escape sequences instead:

  
postrender.quotes = function(passage, content, task) {
function processTextNodes(node) {
if (node.nodeType == 3) { // text node
node.nodeValue = node.nodeValue
.replace(/\b'/g, '\u2019')
.replace(/'\b/g, '\u2018')
.replace(/"(\s|$)/g, '\u201D$1')
.replace(/(\s|^)"/g, '$1\u201C');
} else {
for (var i in node.childNodes) {
processTextNodes(node.childNodes[i]);
}
}
}
processTextNodes(passage);
}
