State becomes broken after failure

import lark
import lark.indenter

class PythonIndenter(lark.indenter.Indenter):
    NL_type = '_NEWLINE'
    OPEN_PAREN_types = ['LPAR', 'LSQB', 'LBRACE']
    CLOSE_PAREN_types = ['RPAR', 'RSQB', 'RBRACE']
    INDENT_type = '_INDENT'
    DEDENT_type = '_DEDENT'
    tab_len = 8

# This is workaround.
#    def process(self, stream):
#        lark.indenter.Indenter.__init__(self)
#        yield from lark.indenter.Indenter.process(self, stream)

parser = lark.Lark.open('python3.lark', parser='lalr', start='file_input', postlex=PythonIndenter())

c = """
for i in ssss.sss:
    print(i)
        print(i)
"""

try:
    tree = parser.parse(c)
except:
    pass

c = """
for i in ssss.sss:
    print(i)
"""
tree = parser.parse(c)
print(tree)

I guess this code is self-describing. After a failure, parser breaks itself (but there is a workaround).

Good catch! Pushed a fix to master

Oh yeah… My bad. Fixed it now, thanks!
