Change the comment marker to <!-- process --><!-- /process -->

$ htmlprocessor file-to-process.html -o processed/file.html --comment-marker process

List option

Create a list of files that were replaced and use that list to streamline the build process.

Note: This new option does not affect in any way the previous existing functionality (i.e. it's backward compatible).

$ htmlprocessor file-to-process.html -o processed/file.html --list wrk/replacement.list

Assumning you have this code in an HTML (or JSP)

  .
  .
  .
  <!-- build:css content/myApplication.min.css -->
  <link rel="stylesheet" href="js/bower_components/bootstrap/dist/css/bootstrap.css" />
  <link rel="stylesheet" href="content/bootstrap-responsive.min.css" needed />
  <link rel="stylesheet" href="content/styles.css" />
  <link rel="stylesheet" href="content/myApplicationStyles.css" />
  <!--/build-->
  .
  .
  .
  <!-- build:js js/myApplication.min.js -->
  <script src="js/bower_components/jquery/dist/jquery.js"></script>
  <script src="js/bower_components/angular/angular.js"></script>
  <script src="js/bower_components/angular-route/angular-route.js"></script>

  <!-- App libs -->
  <script src="app/app.js"></script>
  <script src="app/filters/filters.js"></script>
  <script src="app/controllers/applications.js"></script>
  <!--/build-->
  .
  .
  .

The file "wrk/replacement.list" will contain something like this:

file-to-process.html:js/bower_components/bootstrap/dist/css/bootstrap.css
file-to-process.html:content/bootstrap-responsive.min.css
file-to-process.html:content/styles.css
file-to-process.html:content/myApplicationStyles.css
file-to-process.html:js/bower_components/jquery/dist/jquery.js
file-to-process.html:js/bower_components/angular/angular.js
file-to-process.html:js/bower_components/angular-route/angular-route.js
file-to-process.html:app/app.js
file-to-process.html:app/filters/filters.js
file-to-process.html:app/controllers/applications.js

And you can use these commands to concatenate and eventually minify without having to update the build to tell it where it should pickup each files. Also, in this way it orders the global file content in the same manner as your individual includes originally were.

sh -c "cat `cat wrk/replacement.list | grep '\.js$' | cut -d: -f2` > dist/js/myApplication.js"
sh -c "cat `cat wrk/replacement.list | grep '\.css$' | cut -d: -f2` > dist/css/myApplication.css"

If you processed more than a single "html" file, you can change the grep like this:

... | grep 'file-to-process.html:.*\.js$' | ... > dist/js/myApplication.js
... | grep 'other-file-to-process.html:.*\.js$' | ... > dist/js/myApplicationOther.js

The originating file name is included in the list file for that very purpose.
