Beschreibung:    We will integrate a Cobol Frontend into Eclipse to come up with semantical analyses on Cobol Code.

Preparatory Meeting

Planned for tuesday, January 26th 15:00 in Mi 02.07.034


This lab course will be carried out consolidated during the summer lecture term: Select a convenient date!


Ideally, participants in this course should be familiar with the basics of compiler construction as tought in IN2227 and have profund skills in Java development. As resources, we have several prepared packages:

  1. A step-by-step demonstration project for how to integrate a Java-based language frontend (Scanner/Parser) into Eclipse.
  2. A Cobol tutorial
  3. The official Eclipse FAQ


In this lab course, we will hook a Java based Cobol parser into an IDE (Eclipse). With this plugin, we want to create tools to facilitate practical tasks in program development and maintenance. Recurring practical tasks comprise

  • Integration into an IDE
    • navigation in code
    • finding references
  • Refactoring of code
    • stringent renaming
    • constant propagation/extraction
    • pulling out sections into procedures
    • transform gotos to loops
  • Dataflow analysis in code
    • code slicing depending on data flow
    • preconditions for reachability
    • data size checks
