Headline

A metaprogramming-oriented implementation based on Language:Rascal

Motivation

This contribution serves as an example of how Rascal can be used to create language implementations and IDEs. We show that one can quickly implement a wide range of features with only small amounts of code. Feature:Hierarchical company is implemented as the basic data model in AST form. Feature:Cut is implement as an AST transformation. Feature:Total is implemented as an AST visit. Feature:Parsing is implemented by parsing based on a grammar from which an SGLL parser is generated. (The same syntax as in Contribution:antlrParser is used.) Feature:Visualization is implemented such that the company structure is visualized as a tree and nodes provide info on employer salary with the node size correlating with salary. Editing-related features are implemented through IDE support: editor, syntax highlighting, markers, error messages, folding, outline view.
