Programming Languages: Concepts and Implementation

10.11 Chapter Summary

The main elements of an interpreter language implementation are:

• a read-eval-print loop user interface (e.g., main_func)

• a front end (i.e., scanner and parser, e.g., parser.parse)

• an abstract-syntax data type (e.g., the expression data type TreeNode)

• an interpreter (e.g., the evaluate_expr function)

• supporting data types/structures and libraries (e.g., environment)

Figure 10.4 and Table 10.2 indicate the dependencies between the versions of Camille developed in this chapter, including the programming exercises. Table 10.3 summarizes the concepts and features implemented in the progressive versions of Camille developed in this chapter, including the programming exercises. Table 10.4 outlines the configuration options available ...
