Integrated into your own project

from Ruikowa.ObjectRegex.ASTDef import Ast
from Ruikowa.ErrorHandler import ErrorHandler
from Ruikowa.ObjectRegex.MetaInfo import MetaInfo
from Ruikowa.ObjectRegex.Tokenizer import Tokenizer

from <your own generated parser module> import <top parser>, token_table


import typing as t

def token_func(src_code: str) -> t.Iterable[Tokenizer]:
    return Tokenizer.from_raw_strings(src_code, token_table, ({<the names of tokenizers you would ignore>}, {<the string contents of tokenizers you would ignore>}))

parser = ErrorHandler(<top parser>.match, token_func)

def parse(filename: str) -> Ast:

    return parser.from_file(filename)


print(parse(<filename of your dsl source code>))
