      Parses the given file and returns the dependency information that it contained.
      DependencyInfo parseFile​(java.lang.String filePath, java.lang.String closureRelativePath, java.lang.String fileContents)
      Parses the given file and returns the dependency information that it contained.
      protected boolean parseLine​(java.lang.String line)
      Parses a line of JavaScript, extracting goog.provide and goog.require information.
      JsFileParser setIncludeGoogBase​(boolean include)
      Sets whether we should create implicit provides and requires of the root namespace.

      • 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.
      • parseFile

        public DependencyInfo parseFile​(java.lang.String filePath,
                                        java.lang.String closureRelativePath)
                                 throws java.io.IOException
        Parses the given file and returns the dependency information that it contained.
        Parameters:
        filePath - Path to the file to parse.
        closureRelativePath - Path of the file relative to closure.
        Returns:
        A DependencyInfo containing all provides/requires found in the file.
        Throws:
        java.io.IOException - Thrown if there was an problem reading the given file.
