Semantic correctness of structural editing
Tadeusz Gruźlewski, Zbigniew Weiss · ACM SIGPLAN Notices · 1991
Typical structural editor provides for syntax correctness of an edited text. In this paper some problems are discussed that arise when the semantic analysis is to be included in the tasks of a structural editor. The solution to these problems, already implemented in Modelang editor, is presented. It is based on the concept of multistage editing operations and application of default values. Several examples are given to show how the editor should deal with basic Pascal constructs in order to preserve full semantic accuracy. Additionally, two solutions are proposed to the problem of name maintenance within the structural editor. Structural editing versus conditional compilation is also considered.
