doenetml-to-pretext 0.7.21

Convert DoenetML to PreTeXt using Deno

doenetml-to-pretext

Python package for converting DoenetML to PreTeXt using Deno.

Requires Deno at runtime. Conversions shell out to Deno, so it must be available on your PATH (or install the deno pip package). pip install doenetml-to-pretext alone does not install Deno.

Installation

pip install doenetml-to-pretext

The wheel bundles the compiled JavaScript converter, but you must supply Deno yourself — either a system install on PATH or pip install deno.

Usage

from doenetml_to_pretext import convert_doenetml_to_pretext

doenetml = '<p>Hello <m>\\frac{1}{2}</m></p>'
pretext_xml = convert_doenetml_to_pretext(doenetml)
print(pretext_xml)

Requirements

• Python 3.8+
• Deno

API

convert_doenetml_to_pretext(doenetml: str, timeout: int = 30000) -> str

Converts a DoenetML XML string to PreTeXt XML.

Parameters:

• doenetml (str): DoenetML XML source code
• timeout (int): Timeout in milliseconds for conversion (default: 30000)

Returns:

• str: PreTeXt XML output

Raises:

• ConversionError: If conversion fails
• BrowserError: If browser initialization fails
• TimeoutError: If conversion times out

Examples

Simple conversion

from doenetml_to_pretext import convert_doenetml_to_pretext

xml = '<p>Test</p>'
result = convert_doenetml_to_pretext(xml)

With error handling

from doenetml_to_pretext import convert_doenetml_to_pretext, ConversionError

try:
    result = convert_doenetml_to_pretext('<p>Test</p>')
except ConversionError as e:
    print(f"Conversion failed: {e}")

Development

Install dev dependencies:

pip install -e ".[dev]"

Build a wheel (.whl) (might need pip install build first):

python -m build --wheel

The built wheel will be placed in dist/.

Run tests:

pytest

Publishing

Releases are published to PyPI automatically by the publish-doenetml-to-pretext-python.yml GitHub Actions workflow, using Trusted Publishing (OIDC) — no API token is stored.

• Version: derived from packages/doenetml/package.json, so it stays in lockstep with @doenet/doenetml. There is no separate version to bump here.
• Trigger: GitHub release events only (the same trigger as the npm production release), never pushes to main. Cutting a release whose tag matches the doenetml version publishes the matching wheel.
• Dry run: the workflow can be run manually (workflow_dispatch) targeting TestPyPI to validate packaging before a real release.

The wheel bundles the built JS assets from ../doenetml-to-pretext, so that package must be built first; the workflow (and the npm run build wireit graph) handles this automatically.
