olovDEPRECATION NOTICE - SO LONG AND THANKS FOR ALL THE BITS
ng-annotate is not maintained any longer.
Please check out its successor instead: babel-plugin-angularjs-annotate
Please don't open any issues or pull requests on ng-annotate. No new releaseses will be made.
Feel free to fork the repo and publish your modified version if you want to. More info about the deprecation can be found in Issue #245: The future of ng-annotate.
ng-annotate 
ng-annotate adds and removes AngularJS dependency injection annotations.
Write your code without annotations and mark-up functions to be annotated
with the "ngInject" directive prologue, just like you would
"use strict". This must be at the beginning of your function.
$ cat source.js
angular.module("MyMod").controller("MyCtrl", function($scope, $timeout) {
"ngInject";
...
});Then run ng-annotate as a build-step to produce this intermediary, annotated, result (later sent to the minifier of choice):
$ ng-annotate -a source.js
angular.module("MyMod").controller("MyCtrl", ["$scope", "$timeout", function($scope, $timeout) {
"ngInject";
...
}]);Your minifier will most likely retain the "ngInject" prologues so use sed
or a regexp in your build toolchain to get rid of those on the ng-annotate output.
sed example: ng-annotate -a source.js | sed "s/[\"']ngInject[\"'];*//g".
JavaScript regexp example: source.replace(/["']ngInject["'];*/g, "").
You can also use ng-annotate to rebuild or remove existing annotations. Rebuilding is useful if you like to check-in the annotated version of your source code. When refactoring, just change parameter names once and let ng-annotate rebuild the annotations. Removing is useful if you want to de-annotate an existing codebase that came with checked-in annotations
Installation and usage
npm install -g ng-annotateThen run it as ng-annotate OPTIONS <file>. The errors (if any) will go to stderr,
the transpiled output to stdout.
The simplest usage is ng-annotate -a infile.js > outfile.js.
See OPTIONS.md for command-line documentation.
ng-annotate can be used as a library, see OPTIONS.md for its API.
Implicit matching of common code forms
ng-annotate uses static analysis to detect common AngularJS code patterns. When
this works it means that you do not need to mark-up functions with "ngInject".
For a lot of code bases this works very well (use ng-strict-di to simplify
debugging when it doesn't) but for others it is less reliable and you may prefer
to use "ngInject" instead. For more information about implicit matching see
IMPLICIT.md.
Explicit annotations with ngInject
The recommended function foo($scope) { "ngInject"; ... } can be exchanged
for /*@ngInject*/ function foo($scope) { ... } or
ngInject(function foo($scope) { ... }). If you use the latter form then
then add function ngInject(v) { return v } somewhere in your codebase or process
away the ngInject function call in your build step.
Suppressing false positives with ngNoInject
The /*@ngInject*/, ngInject(..) and "ngInject" siblings have three cousins that
are used for the opposite purpose, suppressing an annotation that ng-annotate added
incorrectly (a "false positive"). They are called /*@ngNoInject*/, ngNoInject(..)
and "ngNoInject" and do exactly what you think they do.
ES6 and TypeScript support
ng-annotate supports ES5 as input so run it with the output from Babel, Traceur,
TypeScript (tsc) and the likes. Use "ngInject" on functions you want annotated.
Your transpiler should preserve directive prologues, if not please file a bug on it.
Highly recommended: enable ng-strict-di
<div ng-app="myApp" ng-strict-di>
Do that in your ng-annotate processed (but not minified) builds and AngularJS will let you know if there are any missing dependency injection annotations. ng-strict-di is available in AngularJS 1.3 or later.

Changes
See CHANGES.md.
Build and test
ng-annotate is written in ES6 constlet style and uses defs.js to transpile to ES5. See BUILD.md for build and test instructions.
