Strictdom

Stictdom is a strictly typed wrapper over Dominate, a Python library for creating and manipulating HTML documents.

Compared to using Dominate directly, strictdom offers:

  • Type hints for code-completion / IntelliSense / IDE hints

  • Type hints and explicit arguments for HTML5 & ARIA conformance at runtime, or at compile-time with mypy.

Features:

  • Nothing new to learn - mostly the same interface as vanilla.

  • Stable versioned interface e.g. strictdom.tags_1 is a frozen view of the spec

  • Consistent handling of both boolean attributes and the weird "boolean-like" attributes like contenteditable or spellcheck.

Example: Vanilla vs Strict

"Vanilla" Dominate

import dominate.tags as dom

print(dom.button("Hello world",
    cls="hello",
    some_invalid_tag="hello",
    onclick="alert('Hello world');"
))

Strictdom

import strictdom.tags_1 as tags

print(tags.button("Hello world",
    class_="hello",
    # some_invalid_tag="hello",
    events=tags.Events(click="alert('Hello world');")
))

some_invalid_tag will raise a runtime error if not removed:

TypeError: __init__() got an unexpected keyword argument 'some_invalid_tag'

Usage

  • Install with sudo pip3 install strictdom --upgrade --no-cache-dir

  • Build from source with python3 make_1.py (requires html5spec) in a sibling directory and test with pytest.

TODO

  • Typechecked ARIA and Event Handlers
