+   *  
+   *  $traversableInfo
+   *  @define mutability
+   *  @define traversableInfo
+   *  This is a base trait of all kinds of $mutability Scala collections. It
+   *  implements the behavior common to all collections, in terms of a method
+   *  `foreach` with signature:
+   * {{{
+   *     def foreach[U](f: Elem => U): Unit
+   * }}}
+   *  Collection classes mixing in this trait provide a concrete 
+   *  `foreach` method which traverses all the
+   *  elements contained in the collection, applying a given function to each.
+   *  They also need to provide a method `newBuilder`
+   *  which creates a builder for collections of the same kind.
+   *  
+   *  A traversable class might or might not have two properties: strictness
+   *  and orderedness. Neither is represented as a type.
+   *  
+   *  The instances of a strict collection class have all their elements
+   *  computed before they can be used as values. By contrast, instances of
+   *  a non-strict collection class may defer computation of some of their
+   *  elements until after the instance is available as a value.
+   *  A typical example of a non-strict collection class is a
+   *  <a href="../immutable/Stream.html" target="ContentFrame">
+   *  `scala.collection.immutable.Stream`</a>.
+   *  A more general class of examples are `TraversableViews`.
+   *  
+   *  If a collection is an instance of an ordered collection class, traversing
+   *  its elements with `foreach` will always visit elements in the
+   *  same order, even for different runs of the program. If the class is not
+   *  ordered, `foreach` can visit elements in different orders for
+   *  different runs (but it will keep the same order in the same run).'
+   * 
+   *  A typical example of a collection class which is not ordered is a
+   *  `HashMap` of objects. The traversal order for hash maps will
+   *  depend on the hash codes of its elements, and these hash codes might
+   *  differ from one run to the next. By contrast, a `LinkedHashMap`
+   *  is ordered because it's `foreach` method visits elements in the
+   *  order they were inserted into the `HashMap`.

HTML mixed mode

+ + + +

The HTML mixed mode depends on the XML, JavaScript, and CSS modes.

+ +

It takes an optional mode configuration + option, scriptTypes, which can be used to add custom + behavior for specific <script type="..."> tags. If + given, it should hold an array of {matches, mode} + objects, where matches is a string or regexp that + matches the script type, and mode is + either null, for script types that should stay in + HTML mode, or a mode + spec corresponding to the mode that should be used for the + script.

+ +

MIME types defined: text/html + (redefined, only takes effect if you load this parser after the + XML parser).

+ +

JavaScript mode

+ + +

+// Demo code (the actual new parser character stream implementation)
+
+function StringStream(string) {
+  this.pos = 0;
+  this.string = string;
+}
+
+StringStream.prototype = {
+  done: function() {return this.pos >= this.string.length;},
+  peek: function() {return this.string.charAt(this.pos);},
+  next: function() {
+    if (this.pos < this.string.length)
+      return this.string.charAt(this.pos++);
+  },
+  eat: function(match) {
+    var ch = this.string.charAt(this.pos);
+    if (typeof match == "string") var ok = ch == match;
+    else var ok = ch && match.test ? match.test(ch) : match(ch);
+    if (ok) {this.pos++; return ch;}
+  },
+  eatWhile: function(match) {
+    var start = this.pos;
+    while (this.eat(match));
+    if (this.pos > start) return this.string.slice(start, this.pos);
+  },
+  backUp: function(n) {this.pos -= n;},
+  column: function() {return this.pos;},
+  eatSpace: function() {
+    var start = this.pos;
+    while (/\s/.test(this.string.charAt(this.pos))) this.pos++;
+    return this.pos - start;
+  },
+  match: function(pattern, consume, caseInsensitive) {
+    if (typeof pattern == "string") {
+      function cased(str) {return caseInsensitive ? str.toLowerCase() : str;}
+      if (cased(this.string).indexOf(cased(pattern), this.pos) == this.pos) {
+        if (consume !== false) this.pos += str.length;
+        return true;
+      }
+    }
+    else {
+      var match = this.string.slice(this.pos).match(pattern);
+      if (match && consume !== false) this.pos += match[0].length;
+      return match;
+    }
+  }
+};
+

+ + + +

+ JavaScript mode supports several configuration options: +

json which will set the mode to expect JSON + data rather than a JavaScript program.
jsonld which will set the mode to expect + JSON-LD linked data rather + than a JavaScript program (demo).
typescript which will activate additional + syntax highlighting and some other things for TypeScript code + (demo).
statementIndent which (given a number) will + determine the amount of indentation to use for statements + continued on a new line.

+ +

MIME types defined: text/javascript, application/json, application/ld+json, text/typescript, application/typescript.
