htmd-py

Python bindings for the htmd Rust library, a fast HTML to Markdown converter.

Installation

pip install htmd-py

Requirements

• Python 3.9+

Options

You can customise the HTML to Markdown conversion with the following options:

• heading_style: Style for headings (values from htmd.HeadingStyle)
• hr_style: Style for horizontal rules (values from htmd.HrStyle)
• br_style: Style for line breaks (values from htmd.BrStyle)
• link_style: Style for links (values from htmd.LinkStyle)
• link_reference_style: Style for referenced links (values from htmd.LinkReferenceStyle)
• code_block_style: Style for code blocks (values from htmd.CodeBlockStyle)
• code_block_fence: Fence style for code blocks (values from htmd.CodeBlockFence)
• bullet_list_marker: Marker for unordered lists (values from htmd.BulletListMarker)
• preformatted_code: Whether to preserve whitespace in inline code (boolean)
• skip_tags: List of HTML tags to skip during conversion (list of strings)

All options are exposed in a simple manner:

import htmd

# Simple conversion with default options
markdown = htmd.convert_html("<h1>Hello World</h1>")
print(markdown)  # "# Hello World"

# Using custom options
options = htmd.Options()
options.heading_style = htmd.HeadingStyle.SETEX
options.bullet_list_marker = htmd.BulletListMarker.DASH
markdown = htmd.convert_html("<h1>Hello World</h1><ul><li>Item 1</li></ul>", options)
print(markdown)

# Skip specific HTML tags
options = htmd.create_options_with_skip_tags(["script", "style"])
markdown = htmd.convert_html("<h1>Hello</h1><script>alert('Hi');</script>", options)
print(markdown)  # "# Hello" (script tag is skipped)

Refer to the htmd docs for all available options.
