- * @ngdoc function
- * @name angular.compile
- * @function
- *
- * @description
- * Compiles a piece of HTML string or DOM into a template and produces a template function, which
- * can then be used to link {@link angular.scope scope} and the template together.
- *
- * The compilation is a process of walking the DOM tree and trying to match DOM elements to
- * {@link angular.markup markup}, {@link angular.attrMarkup attrMarkup},
- * {@link angular.widget widgets}, and {@link angular.directive directives}. For each match it
- * executes corresponding markup, attrMarkup, widget or directive template function and collects the
- * instance functions into a single template function which is then returned.
- *
- * The template function can then be used once to produce the view or as it is the case with
- * {@link angular.widget.@ng:repeat repeater} many-times, in which case each call results in a view
- * that is a DOM clone of the original template.
- *
- <pre>
- // compile the entire window.document and give me the scope bound to this template.
- var rootScope = angular.compile(window.document)();
-
- // compile a piece of html
- var rootScope2 = angular.compile('<div ng:click="clicked = true">click me</div>')();
-
- // compile a piece of html and retain reference to both the dom and scope
- var template = angular.element('<div ng:click="clicked = true">click me</div>'),
- scope = angular.compile(template)();
- // at this point template was transformed into a view
- </pre>
- *
- *
- * @param {string|DOMElement} element Element or HTML to compile into a template function.
- * @returns {function(scope[, cloneAttachFn])} a template function which is used to bind template
- * (a DOM element/tree) to a scope. Where:
- *
- * * `scope` - A {@link angular.scope Scope} to bind to.
- * * `cloneAttachFn` - If `cloneAttachFn` is provided, then the link function will clone the
- * `template` and call the `cloneAttachFn` function allowing the caller to attach the
- * cloned elements to the DOM document at the appropriate place. The `cloneAttachFn` is
- * called as: <br/> `cloneAttachFn(clonedElement, scope)` where:
- *
- * * `clonedElement` - is a clone of the original `element` passed into the compiler.
- * * `scope` - is the current scope with which the linking function is working with.
- *
- * Calling the template function returns the element of the template. It is either the original element
- * passed in, or the clone of the element if the `cloneAttachFn` is provided.
- *
- * It is important to understand that the returned scope is "linked" to the view DOM, but no linking
- * (instance) functions registered by {@link angular.directive directives} or
- * {@link angular.widget widgets} found in the template have been executed yet. This means that the
- * view is likely empty and doesn't contain any values that result from evaluation on the scope. To
- * bring the view to life, the scope needs to run through a $digest phase which typically is done by
- * Angular automatically, except for the case when an application is being
- * {@link guide/dev_guide.bootstrap.manual_bootstrap} manually bootstrapped, in which case the
- * $digest phase must be invoked by calling {@link angular.scope.$apply}.
- *
- * If you need access to the bound view, there are two ways to do it:
- *
- * - If you are not asking the linking function to clone the template, create the DOM element(s)
- * before you send them to the compiler and keep this reference around.
- * <pre>
- * var scope = angular.injector()('$rootScope');
- * var element = angular.compile('<p>{{total}}</p>')(scope);
- * </pre>
- *
- * - if on the other hand, you need the element to be cloned, the view reference from the original
- * example would not point to the clone, but rather to the original template that was cloned. In
- * this case, you can access the clone via the cloneAttachFn:
- * <pre>
- * var original = angular.element('<p>{{total}}</p>'),
- * scope = someParentScope.$new(),
- * clone;
- *
- * angular.compile(original)(scope, function(clonedElement, scope) {
- * clone = clonedElement;
- * //attach the clone to DOM document at the right place
- * });
- *
- * //now we have reference to the cloned DOM via `clone`
- * </pre>
- *
- *
- * Compiler Methods For Widgets and Directives:
- *
- * The following methods are available for use when you write your own widgets, directives,
- * and markup. (Recall that the compile function's this is a reference to the compiler.)
- *
- * `compile(element)` - returns linker -
- * Invoke a new instance of the compiler to compile a DOM element and return a linker function.
- * You can apply the linker function to the original element or a clone of the original element.
- * The linker function returns a scope.
- *
- * * `comment(commentText)` - returns element - Create a comment element.
- *
- * * `element(elementName)` - returns element - Create an element by name.
- *
- * * `text(text)` - returns element - Create a text element.
- *
- * * `descend([set])` - returns descend state (true or false). Get or set the current descend
- * state. If true the compiler will descend to children elements.
- *
- * * `directives([set])` - returns directive state (true or false). Get or set the current
- * directives processing state. The compiler will process directives only when directives set to
- * true.
- *
- * For information on how the compiler works, see the
- * {@link guide/dev_guide.compiler Angular HTML Compiler} section of the Developer Guide.
