Earley doesn't always pinpoint line & number of parse error about lark HOT 10 CLOSED

Oh yeah, for sure. It worked perfectly. Thank you much!!!

from lark.

Just pushed a fix to master. It was easier to solve than I anticipated. I'm closing the issue, but feel free to reopen it if there is still an issue.

Sorry to bug, but I thought the line/col number would be added in these messages:

File "/home/sgerasenko/lark/lark/parsers/xearley.py", line 150, in parse
    raise ParseError('Incomplete parse: Could not find a solution to input')
lark.common.ParseError: Incomplete parse: Could not find a solution to input

Did I misunderstand something?

from lark.

Okay, it might be a bit more challenging, but I'll give it a try.

from lark.

I changed this exception to be more informative / actionable. Please try the latest version at master and let me know if the new exception info is sufficient.

from lark.

It's a bit better because it tells me what it was expecting:

lark.common.ParseError: Unexpected end of input! Expecting a terminal of: []

but no line number right? The challenge is that my input file is ~1300 lines long and to understand where it failed requires something like removing half of the file, seeing if the error is gone, removing the half of what was left, etc. I can get by though if it's too difficult. Thanks for the effort!

from lark.

Yes, I see. It's a difficult error to report, because it's not completely clear, when it occurs, at which point did the parse go wrong. I'll see if I can do better.

Btw, are you getting Expecting a terminal of: [] ? That list isn't supposed to be empty.

from lark.

I generated that error by putting some garbage in my input -- just to see what the error would look like. No special meaning there.

from lark.

accidentally put what was meant for issue 44 here -- ignore this.

It's been two years (wow!), so I'm closing this issue. If this is still of interest, feel free to reopen or open a new issue, and I will try to give it more attention.
