Hi,
I just wanted to let you know that I started to rework the PetitParser browser.
There are several things that have changed:
- it is modular, currently being formed of 3 distinct browsers. To give them a try (I also attached a couple of screenshots): PPAllParsersBrowser open. PPParserBrowser openOn: PPArithmeticParser. PPParserInspector openOn: PPArithmeticParser new.
- it only relies on the Glamour mechanisms without state in the implementation code. This was more of a validation that the engine is expressive enough
- it has a slightly different layout
- the Mondrian map can be used as a navigation, so clicking on a node will focus the browser on that production.
- it uses a tree widget for the debugger so we can scale for large debugging traces
What is still to do: - install the associated instance variable for each newly created production. - introduce parser renaming refactoring. This would entail triggering both a method and an instance var rename. - add the possibility to remove a production. This would entail removing a method and the corresponding instance var. - make the morph graph view interactive. - add a new grammar class. - integrate tests for each production. This would involve being able to browse tests associated to a production, run, add and remove them.
If these would work, we would have a true IDE and for most parts we would not need the Smalltalk editor for building parsers. But, I could use some help on the todos left, especially on the refactorings.
Cheers, Doru
