AVWX

AVWX is a global aviation weather fetching and parsing engine. It sources reports from a variety of government sources, parses individual elements, and calculates additional information like flight rules and time range interpolation.

AVWX currently supports:

• Station data and search
• METAR
• TAF
• PIREP
• NBM (NBH, NBS, NBE)
• GFS (MAV, MEX)

Install

The easiest way to get started is to download the library from pypi using pip:

python -m pip install avwx-engine

Basic Usage

Reports use ICAO idents when specifying the desired station. Exceptions are thrown if a potentially invalid ident is given.

>>> import avwx
>>>
>>> metar = avwx.Metar('KJFK')
>>> metar.station.name
'John F Kennedy International Airport'
>>> metar.update()
True
>>> metar.data.flight_rules
'IFR'

Note: This library requires Python 3.7 or above

Develop

Download and install the source code and its development dependencies:

git clone https://github.com/avwx-rest/avwx-engine
cd avwx-engine
python -m pip install -Ur requirements.txt
python -m pip install -e .

Code formatting should be handled by hooks in pre-commit. Before committing any code, be should to install pre-commit into the local git project:

pre-commit install

Test

The easiest way to test the package is using the nox library, which is installed as a dev dependency. It will manage all tests, sessions, supported versions (when available), and cleanup. The tests will pick up the local version of avwx.

nox

If you want to run the tests directly, the test suite was built while using the pytest library, which is also installed as a dev dependency.

pytest

The end-to-end test files were generated using util/build_tests.py and placed into tests/{report}. Because Timestamp generation interprets the text based on the current date, Timestamp objects are nullified in the end-to-end tests.

Docs

AVWX uses mkdocs to build its documentation. It's just another install:

python -m pip install .[docs]

To serve the docs during development:

cd docs
mkdocs serve
