Incorrect syntax tree

[y912765390]

Hi I'm looking at ast online parsing using our parsing method here. But if the text is wrong halfway through, and the grammar crashes, I wonder if we can make something like ANTlR4 so that this node or its parent node is the wrong node without affecting the generation of the entire other syntax tree

Hello. @y912765390

Yes you can have fault tolerance with Chevrotain based Parsers.

• https://sap.github.io/chevrotain/docs/features/fault_tolerance.html

One point to consider is that this Java Parser uses very advanced lookahead logic
to keep the grammar implementation closely aligned with the official Java specifications.
I am uncertain how this advanced lookedahead logic would interact with the error recovery / fault tolerance capabilities...

Cheers.
