Was there a version 0.96?

I am in the midst of updating and migrating a very old project to .NET 6 and beyond. It is using version 0.96 of Irony, which I cannot find any record of on the internet (which is a concern).

However, when I upgrade, it complains that the Parent field being used on ParseTreeNode does not exist. Looking through the various GitHub repositories of Irony, I can’t find any record of this field ever existing.

Having a peek, I can see that ParseTreeNode.ParentNode was being set within the GetResultNode method in the ReduceParserAction class.

Does anyone have any knowledge of this field ever existing? Did the previous developers just roll their own and forget to document it?

Hi,
can't say for sure what happened at these old times. I would just recommend to move to latest version (it is quite stable, nothing changed for years), and figure out all necessary changes, by try/fail/try again -succeed process. It's not worth investigating how this change happened in Irony, just modify the code to most likely alternative - I bet the ParentNode is a replacement/rename. in the end, it should all work. Good luck.

Thank you for the response.

There is a secondary activity to merge two parts of our code base that use Irony to the same code path and can see one does not use this enigmatic field but is achieving loosely the same results so will have to perform this task.
