上述代码你跑成功了吗?是不是还有许多不解的地方?没关系下面有你想要的

开始使用mistune

mistune简单使用

import mistune
mistune.html(YOUR_MARKDOWN_TEXT)

mistune高级用法(自定义mistune)

import mistune
markdown = mistune.create_markdown()
markdown('YOUR_MARKDOWN_TEXT')

参数

参数	释义	默认值	备注
escape	HTML转义	TRUE	默认情况下将html文本转义,如:[1]
plugins	启用的插件功能	None	导入插件后添加到plugins中启用插件,他的传入值为列表,如:[2]
hard_wrap	将每一新行分成<br>	False	启用后md文件中的每一行都会解析成单独一行
renderer	默认选项有AST解析器mistune.AstRenderer()和HTML解析器mistune.HTMLRenderer() , 也可以自定义[3]

mistune中插件

插件使用方法(以 删除线(strikethrough) 为例)

mistune.html() 默认支持strikethrough. 创建自己的markdown实例:

markdown = mistune.create_markdown(plugins=['strikethrough'])

其他创建你自己的markdown实例的方法:

from mistune.plugins import plugin_strikethrough
renderer = mistune.HTMLRenderer()
markdown = mistune.Markdown(renderer, plugins=[plugin_strikethrough])

解析器

使用解析器

你可以使用自己的渲染器来自定义HTML的输出.创建一个mistune.HTMLRenderer的子类:

import mistune
from mistune import escape
class MyRenderer(mistune.HTMLRenderer):
    def codespan(self, text):
        if text.startswith('$') and text.endswith('$'):
            return '<span class="math">' + escape(text) + '</span>'
        return '<code>' + escape(text) + '</code>'
# 使用自定义解析器
markdown = mistune.create_markdown(renderer=MyRenderer())
print(markdown('hi `$a^2=4$`'))

可用的解析器功能列表

1.内联级 inline level

text(self, text)

link(self, link, text=None, title=None)

image(self, src, alt="", title=None)

emphasis(self, text)

strong(self, text)

codespan(self, text)

linebreak(self)

newline(self)

inline_html(self, html)

2.块级 block level

paragraph(self, text)

heading(self, text, level)

heading(self, text, level, tid) # when TOC directive is enabled

thematic_break(self)

block_text(self, text)

block_code(self, code, info=None)

block_quote(self, text)

block_html(self, html)

block_error(self, html)

list(self, text, ordered, level, start=None)

list_item(self, text, level)

3.由删除插件提供 provided by strikethrough plugin

strikethrough(self, text)

4.由表格插件提供 provide by table plugin

table(self, text)

table_head(self, text)

table_body(self, text)

table_row(self, text)

table_cell(self, text, align=None, is_head=False)

5.由注胶插件提供 provided by footnotes plugin

footnote_ref(self, key, index)

footnotes(self, text)

footnote_item(self, text, key, index)

6.确定最终呈现内容(定义输出) Finalize rendered content (define output)

finalize(self, data)

自定义渲染器

Midtune 支持开发者自定义渲染器功能,例如,创建一个代码高亮渲染器

import mistune
from pygments import highlight
from pygments.lexers import get_lexer_by_name
from pygments.formatters import html
class HighlightRenderer(mistune.HTMLRenderer):
    def block_code(self, code, lang=None):
        if lang:
            lexer = get_lexer_by_name(lang, stripall=True)
            formatter = html.HtmlFormatter()
            return highlight(code, lexer, formatter)
        return '<pre><code>' + mistune.escape(code) + '</code></pre>'
markdown = mistune.create_markdown(renderer=HighlightRenderer())
print(markdown('```python\nassert 1 == 1\n```'))

创建插件

Mistune有一些内置插件，您可以查看Mistune/plugins中的源代码，了解如何编写插件。让我们以GitHub Wiki链接为例：

一个mistune插件示例:

# 为Wiki链接定义正则表达式 define regex for Wiki links
import mistune
WIKI_PATTERN = (
    r'\[\['                   # [[
    r'([\s\S]+?\|[\s\S]+?)'   # Page 2|Page 2
    r'\]\](?!\])'             # ]]
)
# 定义如何解析匹配项 define how to parse matched item
def parse_wiki(inline, m, state):
    # ``inline`` is ``md.inline``, see below
    # "m"是匹配的正则表达式项 ``m`` is matched regex item
    text = m.group(1)
    title, link = text.split('|')
    return 'wiki', link, title
# 定义如何渲染HTML define how to render HTML
def render_html_wiki(link, title):
    return f'<a href="https://www.cnblogs.com/lueye/p/{link}">{title}</a>'
def plugin_wiki(md):
    # 这是一个内联语法，因此我们将wiki规则注册到md.inline中
    # this is an inline grammar, so we register wiki rule into md.inline
    # 语法: md.inline.register_rule(name, 正则表达式, 函数[解析匹配项])
    # 注意名字要一直匹配
    md.inline.register_rule('wiki', WIKI_PATTERN, parse_wiki)
    # 将wiki规则添加到活动规则中
    # add wiki rule into active rules
    md.inline.rules.append('wiki')
    # 添加HTML渲染器 add HTML renderer
    if md.renderer.NAME == 'html':
        md.renderer.register('wiki', render_html_wiki)
# 使用这个插件 use this plugin
markdown = mistune.create_markdown(plugins=[plugin_wiki])
