any2htpy 0.1.2

a HTML/SVG/MathML to htpy converter

any2htpy

any2htpy is a principled converter for HTML/SVG and MathML to htpy inspired by html2htpy, the built-in tool for htpy.

Unlike html2htpy any2htpy uses a feature-complete HTML parser called justhtml.

Features

• adheres to SVG and MathML
• preserves case-sensitive attributes such as SVG viewBox
• preserves SVG path commands and other non-class attribute values with spaces
• tries best-effort DOM for malformed HTML
• properly preserves whitespace for respective tags
• only supports class_ syntax to allow stable parsing by TailwindCSS

A few things any2htpy needs to fix to be better suited for :

• auto-detect if code is just a fragment or a whole document
• boolean attributes are not yet detected (use dict syntax)
• special attribute detection for AlpineJS or HTMX
  • specifically passing HTMX events : or AlpineJS @

Things that any2htpy will not do:

• add the import htpy code
• add the shorthand syntax of htpy

Usage

usage: any2htpy [-h] [--input INPUT] [--stdin] [--debug] [--prefix PREFIX] [--fragment]

options:
  -h, --help       show this help message and exit
  --input INPUT    input as string or file
  --stdin          use stdin as input
  --debug          generate debug output
  --prefix PREFIX  use a prefix for the tags
  --fragment       use htpy fragment

input through stdin

[me@machine ] echo "<p>Hello World</p>" | uv run any2htpy --stdin --prefix htpy
htpy.p["Hello World"]

Disclaimer

As an AI-skeptic, specifically regarding code and software in general, justhtml is not exactly the obvious choice or more precisely the exact opposite one. However, the heavy test-rig with thousands of tests and the use as a parser without introducing it as a dependency in the resulting code make it a better choice than any other native Python parser library.
