In this section, we introduce the C++11 header files that make up the Attribute-Flow Parser Library. The remainder of this wiki discuss the details of Attribute-Flow Grammars and the Attribute-Flow Parser Library. Finally, we provide a collection of C++ programs that implement different AFParsers to perform various tasks.

Header File Descriptions

  • parser.h:
    • Defines the BaseParser and Parser classes
    • Defines the parsing engine
    • Defines operator overloads that create AFParser objects
  • parsetree.h:
    • Defines the ParseTree class
    • Represents a parse tree for some input
  • prettyparser.h:
    • Defines the PrettyParser class
    • Allows printing of ParseTree objects to Graphviz Dot and stdout
    • Allows printing of BaseParser objects to stdout
  • tokenizer.h:
    • Defines the Tokenizer class
    • Holds input for AFParser objects
  • flextokenizer.h:
    • Defines the FlexTokenizer class
    • Tokenizes input using Flex
    • Can tokenize string or file descriptor
  • tokenstream.h:
    • Defines the TokenStream and parsing_error class
    • Handles extraction and storing of semantic value into out-flow variable
    • Allows flow variables to be of a non-primitive type
