https://coveralls.io/repos/lepture/mistune/badge.png?branch=master

Features

Pure Python. Tested in Python 2.6+, Python 3.3+ and PyPy.
Very Fast. It is the fastest in all pure Python markdown parsers.
More Features. Table, footnotes, autolink, fenced code etc.

Installation

Installing mistune with pip:

$ pip install mistune

If pip is not available, try easy_install:

$ easy_install mistune

Cython Feature

Mistune can be faster, if you compile with cython:

$ pip install cython mistune

Basic Usage

A simple API that render a markdown formatted text:

import mistune

mistune.markdown('I am using **markdown**')
# output: <p>I am using <strong>markdown</strong></p>

Mistune has all features by default. You don’t have to configure anything.

Renderer

Like misaka/sundown, you can influence the rendering by custom renderers. All you need to do is subclassing a Renderer class.

Here is an example of code highlighting:

import mistune
from pygments import highlight
from pygments.lexers import get_lexer_by_name
from pygments.formatters import HtmlFormatter

class MyRenderer(mistune.Renderer):
    def block_code(self, code, lang):
        if not lang:
            return '\n<pre><code>%s</code></pre>\n' % \
                mistune.escape(code)
        lexer = get_lexer_by_name(lang, stripall=True)
        formatter = HtmlFormatter()
        return highlight(code, lexer, formatter)

renderer = MyRenderer()
md = mistune.Markdown(renderer=renderer)
print(md.render('Some Markdown text.'))

Block Level

Here is a list of block level renderer API:

block_code(code, language=None)
block_quote(text)
block_html(html)
header(text, level, raw=None)
hrule()
list(body, ordered=True)
list_item(text)
paragraph(text)
table(header, body)
table_row(content)
table_cell(content, **flags)

The flags tells you whether it is header with flags['header']. And it also tells you the align with flags['align'].

Span Level

Here is a list of span level renderer API:

autolink(link, is_email=False)
codespan(text)
double_emphasis(text)
emphasis(text)
image(src, title, alt_text)
linebreak()
link(link, title, content)
tag(html)
strikethrough(text)
text(text)

Options

Here is a list of all options that will affect the rendering results:

mistune.markdown(text, escape=True)

md = mistune.Markdown(escape=True)
md.render(text)

escape: if set to True, all raw html tags will be escaped.
hard_wrap: if set to True, it will has GFM line breaks feature.
use_xhtml: if set to True, all tags will be in xhtml, for example: <hr />.
parse_html: parse text in block level html.

Lexers

Sometimes you want to add your own rules to Markdown, such as GitHub Wiki links. You can’t archive this goal with renderers. You will need to deal with the lexers, it would be a little difficult for the first time.

We will take an example for GitHub Wiki links: [[Page 2|Page 2]]. It is an inline grammar, which requires custom InlineGrammar and InlineLexer:

import copy

class MyInlineGrammar(InlineGrammar):
    # it would take a while for creating the right regex
    wiki_link = re.compile(
        r'\[\['                   # [[
        r'([\s\S]+?\|[\s\S]+?)'   # Page 2|Page 2
        r'\]\](?!\])'             # ]]
    )


class MyInlineLexer(InlineLexer):
    default_features = copy.copy(InlineLexer.default_features)

    # Add wiki_link parser to default features
    # you can insert it any place you like
    default_features.insert(3, 'wiki_link')

    def __init__(self, renderer, rules=None, **kwargs):
        if rules is None:
            # use the inline grammar
            rules = MyInlineGrammar()

        super(MyInlineLexer, self).__init__(renderer, rules, **kwargs)

    def output_wiki_link(self, m):
        text = m.group(1)
        alt, link = text.split('|')
        # you can create an custom render
        # you can also return the html if you like
        return self.renderer.wiki_link(alt, link)

You should pass the inline lexer to Markdown parser:

inline=MyInlineLexer(renderer)
markdown = Markdown(renderer, inline=inline)
markdown('[[Link Text|Wiki Link]]')

It is the same with block level lexer. It would take a while to understand the whole mechanism. But you won’t do the trick a lot.
