report the faulty character / line / column / offset when no parse trees are generated

[valyrie97]

Is your feature request related to a problem? Please describe. Im trying to catch syntax errors in a custom plaintext file format, and when the parse fails, i simply receive no parse trees, with no information about where it failed.

Describe the solution you'd like I'd like to see a line/column or character index, or something along those lines, that i can use to log to the user where the parsing has failed.
