Templates
=========
This example shows how to use Lark's templates to achieve cleaner grammars
"""
from lark import Lark
grammar = r"""
start: list | dict
list: "[" _seperated{atom, ","} "]"
dict: "{" _seperated{key_value, ","} "}"
key_value: atom ":" atom
_seperated{x, sep}: x (sep x)* // Define a sequence of 'x sep x sep x ...'
atom: NUMBER | ESCAPED_STRING
%import common (NUMBER, ESCAPED_STRING, WS)
%ignore WS

print(parser.parse('[1, "a", 2]'))
print(parser.parse('{"a": 2, "b": 6}')) |
