A markdown parser

Project description


A naive markdown parser in pure python.

WARNING: The library will never attempt to do any sanitization on the input. If used for user generated content it is highly recommended to use an external sanitization library.


meltdown currently only supports Python 3.12.

pip install meltdown


from meltdown import MarkdownParser, HtmlProducer

doc = MarkdownParser().parse("# Hello **friends**!")
html = HtmlProducer().produce(doc)


The default HtmlProducer is heavily inspired by pandoc, however, if you are unhappy you can easily write your own producer or if only some formattings are unwanted override the default methods.

In the following example we change the bold formatting form <strong> to <b>:

from meltdown import MarkdownParser, HtmlProducer
from meltdown.Nodes import *
from typing import Self

class CustomHtmlProducer(HtmlProducer):
    def visit_bold(self: Self, node: BoldNode):
        self._output += "<b>"
        for child in node.children:
        self._output += "<b>"

doc = MarkdownParser().parse("# Hello **friends**!")
html = CustomHtmlProducer().produce(doc)


Run all tests

python -m pytest
