Unable to get the parsed tree data when statement is incomplete

[jillyj]

Generated parser: kestrelParser.zip

Code

function handle_errors(e) { return true; }

  try {
    treeData = parser.parse("proc2 =", null, handle_errors).children[0];
  } catch (e) {
    console.debug("uncaught error:", e)
  }

Expected: can get treeData after parsing even if the statement is incomplete.

Well, before parsing is complete, there is no single tree, but several fragments of trees.

You can find them in the instance of the parser state, ParserState.value_stack (https://github.com/lark-parser/lark/blob/master/lark/parsers/lalr_parser.py#L92).

If you have an idea on how to make an API out of that, let me know.

Ok, I got it. I'll get the data from ParserState.value_stack. Thanks!

Happy to help.
