Qt中使用

需要注意的是Qt对HTM5的支持非常不完整，需要将H5转为H4
HtmlFormatter( full=True, style='colorful', noclasses=True, nobackground=True )这几个参数是必须的，否则不生效，

# coding:utf-8
import json
from typing import Union, Literalfrom pygments import highlight
from pygments.formatters import HtmlFormatter
from pygments.lexers import get_lexer_by_name
