Cant read `meta` from Tree or Token? about lark HOT 5 CLOSED

Well, you have to set propagate_positions=True to enable the Tree meta .

Ahh thanks so much @erezsh :) Really appreciate that you took the time. I did not spot that in the docs... I searched for a bunch of things along the lines of "metadata" but i guess thats no substitute for carefully reading the whole thing

I changed

lgram = Lark(grammar_text, propagate_positions=True)

and

print(f"Comment: line Token({line=}) Tree({meta.line=})")

Comment: line Token(line=53) Tree(meta.line=2)
exponent
Comment: line Token(line=53) Tree(meta.line=4)

Now I get the correct line when reading the metadata from the Tree(meta.line), but interestingly the same seemingly incorrect result when reading Token(line). Probably i will need to do some more careful reading 😕

I'm sure you'll figure it out.

I suggest starting with a minimal example and debugging it. (minimal grammar, minimal input)

If you have it, but still can't figure it out, paste it here and I'll take a look.

Ahhh now I get it... of course, Token(line) is the line that the rule comment was declared in the grammar 🤦‍♂️
