Tutorial 2 Altering Markdown Rendering

Lets use files:

ImageExtension.py

from markdown.treeprocessors import Treeprocessor
from markdown.extensions import Extension


class InlineImageProcessor(Treeprocessor):
    def run(self, root):
        # Modify the HTML here
        print("Hello world")


class ImageExtension(Extension):
    def __init__(self, **kwargs):
        self.config = {'hosts' : [[], 'List of approved hosts']}
        super(ImageExtension, self).__init__(**kwargs)

    def extendMarkdown(self, md):
        md.treeprocessors.register(InlineImageProcessor(md), 'inlineimageprocessor', 15)

input.md

![a local image](/path/to/image.jpg "A title.")

![a remote image](http://example.com/image.jpg  "A title.")

test.py

import markdown
import sys
with open("input.md", "r", encoding="utf-8") as input_file:
    input = input_file.read()

from ImageExtension import ImageExtension
html = markdown.markdown(input, extensions=[ImageExtension()])
print(html)

Run with python test.py > test.html and open html file in browser or text editor
