Selectors

[ThatXliner]

Kind of like your other project plyplus, I think Lark might benefit from CSS-ish queries and selectors. Because, AFIAK, writing a transformer/visitor is the only way to interact with the tree officially.

Can you give me examples of situations or tasks which would be best done with selectors?

My experience was that they weren't that useful, and most of the time could be replaced with find_data or scan_values.

[ThatXliner]

Oh ok. But finding tokens would be nice. There's no issue for that, right?

[MegaIng]

.... That is what scan_values is there for.

[ThatXliner]

Huh? lark.Tree doesn't have a scan_values. At least in the docs...

[erezsh]

@ThatXliner You're right, it's not documented. I will add it now
