  • Method Details

    • setIncludeGoogBase

      public JsFileParser setIncludeGoogBase(boolean include)
      Sets whether we should create implicit provides and requires of the root namespace. When generating deps files, you do not want this behavior. Deps files need base.js to run anyway, so they don't need information about it. When generating abstract build graphs, you probably do want this behavior. It will create an implicit dependency of all files with provides/requires on base.js.
      Returns:
      this for easy chaining.
