## Methods

- ###

  `directive(name, directiveFactory);`

  Register a new directive with the compiler.

  #### Parameters

  Param | Type | Details
  --- | --- | ---
  name | string Object | Name of the directive in camel-case (i.e. `ngBind` which will match as `ng-bind`), or an object map of directives where the keys are the names and the values are the factories.
  directiveFactory | function()Array | An injectable directive factory function. See directive for more info.

  #### Returns

  ng.$compileProvider | Self for chaining.

- ###

  `aHrefSanitizationWhitelist([regexp]);`

  Retrieves or overrides the default regular expression that is used for whitelisting of safe urls during a[href] sanitization.

  The sanitization is a security measure aimed at preventing XSS attacks via html links.

  Any url about to be assigned to a[href] via data-binding is first normalized and turned into an absolute url. Afterwards, the url is matched against the `aHrefSanitizationWhitelist` regular expression. If a match is found, the original url is written into the dom. Otherwise, the absolute url is prefixed with `'unsafe:'` string and only then is it written into the DOM.

  #### Parameters

  Param | Type | Details
  --- | --- | ---
  regexp (optional) | RegExp | New regexp to whitelist urls with.

  #### Returns

  RegExp ng.$compileProvider | Current RegExp if called without value or self for chaining otherwise.

- ###

  `imgSrcSanitizationWhitelist([regexp]);`

  Retrieves or overrides the default regular expression that is used for whitelisting of safe urls during img[src] sanitization.

  The sanitization is a security measure aimed at prevent XSS attacks via html links.

  Any url about to be assigned to img[src] via data-binding is first normalized and turned into an absolute url. Afterwards, the url is matched against the `imgSrcSanitizationWhitelist` regular expression. If a match is found, the original url is written into the dom. Otherwise, the absolute url is prefixed with `'unsafe:'` string and only then is it written into the DOM.

  #### Parameters

  Param | Type | Details
  --- | --- | ---
  regexp (optional) | RegExp | New regexp to whitelist urls with.

  #### Returns

  RegExp ng.$compileProvider | Current RegExp if called without value or self for chaining otherwise.

- ###

  `debugInfoEnabled([enabled]);`

  Call this method to enable/disable various debug runtime information in the compiler such as adding binding information and a reference to the current scope on to DOM elements. If enabled, the compiler will add the following to DOM elements that have been bound to the scope

  - `ng-binding` CSS class
  - `$binding` data property containing an array of the binding expressions

  You may want to disable this in production for a significant performance boost. See Disabling Debug Data for more.

  The default value is true.

  #### Parameters

  Param | Type | Details
  --- | --- | ---
  enabled (optional) | boolean | update the debugInfoEnabled state if provided, otherwise just return the current debugInfoEnabled state

  #### Returns

  * | current value if used as getter or itself (chaining) if used as setter
