scriptタグの中身をprettyprintする

README.md

jQuery と google-code-prettify が必要

pputil.js

// #!prettyprint <- この行のあるスクリプトが対象
$(function() {
    var count = 0;
    $("script").each(function(i, e) {
        var source = e.text;
        if (source.indexOf("#!"+"prettyprint") === -1) return;
        
        source = source.replace(/\/\/\s*<!\[CDATA\[/, "");
        source = source.replace(/\/\/\s*\]\]>/, "");
        source = source.replace(/<!\-\-/, "");
        source = source.replace(/\/\/\s*-->/, "");
        source = source.replace(new RegExp("//\\s*#!"+"prettyprint.*$", "gm"), "");
        source = source.replace(/^\s*$/gm, "");
        source = source.replace(/^\n/, "");
        
        $(document.createElement("pre"))
            .addClass("prettyprint")
            .text(source)
            .insertAfter(e);
        count += 1;
    });
    if (count > 0) prettyPrint();
});
