tac2iwxxm 0.1.0

General TAC → IWXXM converter (F6)

tac2iwxxm

General TAC → IWXXM converter package (F6 / F14). MIT licensed.

See ADR-013 / ADR-014 / ADR-016 / ADR-017.

Install

# Convert only (no validators)
pip install tac2iwxxm

# Convert + TAC lint + IWXXM XSD/Schematron (F14)
pip install 'tac2iwxxm[validate]'

The [validate] extra depends on tac-validate and iwxxm-validate (E10-20). Convert works without the extra.

from tac2iwxxm import convert

result = convert(
    "METAR KJFK 231751Z 18012KT 10SM FEW040 15/07 A3005=",
    product="METAR",
)
assert result.ok and result.xml

With [validate] installed:

from tac_validate import lint
from iwxxm_validate import validate_iwxxm

assert lint(tac, product="METAR").ok
assert validate_iwxxm(result.xml, iwxxm_version="2025-2").ok

Native extension (PyO3)

Optional Rust hotspots live under rust/ and import as tac2iwxxm._rust (ADR-017). Pure Python remains the default uv sync path.

# requires rustc + maturin
