John has started some initial work on a Java/Eclipse variant of Prolint. This variant of Prolint has the advantage of easy access to ProRefactor's output - especially its symbol tables and scoping information.
Questions about getting the original Prolint into Eclipse, and other "project direction" type questions, are completely unanswered. It's all very open for you to dive in, write some code, and help determine how best to make Prolint an integral part of working with 4GL/ABL in Eclipse and OpenEdge Architect.
Here's what has been done so far:
The Prolint actions in the Navigation view's menu can be executed against any combination of projects, folders, and files.
Since it relies heavily on ProRefactor, it is currently kept in the ProRefactor project repository.
