How to get a position of a token from ParseErrorContext

[artempyanykh]

I'm trying to implement error recovery with fslexyacc. I've defined parse_error_rich function. The argument to the function is ctx: ParseErrorContext<GeneratedParser.token>*.

I see that ctx.ParseState has some positional information, but ParseState.ResultRange gives some weird positions not really related to my input, and the rest of the methods requires an int argument, however it's not really clear what sort of argument I should supply or where to get it.

I'm a bit stuck at this point, and would really appreciate an advice!

Version of FsLexYacc: 11.0.0-beta1

*) Actually, getting access to the generated token type inside parse_error_rich is not possible because of the order of type definitions, but that's a different issue.

This is an issue I ran into recently. I am trying to figure out how to get better error information from ParseState too.
