gridded

A high-level general-use API for working with regular, curvilinear, and unstructured grids.

This project is under heavy development and is likely to change drastically until the 1.0 release.

Development (conda)

Setup

conda create -n gridded -c conda-forge --file requirements.txt
source activate gridded

NOTE: If running Python less than 3.5, you should install cyordereddict:

conda install -c conda-forge cyordereddict

Tests

Be sure to run python setup.py develop. Then you can run the suite with py.test

Creating Your Own gridded-Compatible object

gridded uses Python's setuptools entry_points mechanism to discover gridded-Compatible GridAdapter objects. To provide a GridAdapter from your package, create an object similar to:

class SomeGridAdapter(object):
    ...
    @classmethod
    def is_mine(cls, *args, **kwargs):
        """
        Check passed arguments to see if this class should interpret the arguments
        as being compatible with itself. For example, a `CF` adapter object
        may check for the global attribute `Conventions` in this method if the
        first argument is a netCDF4-python Dataset object or an xarray Dataset
        object. Return True if so. The possible argument are yet to be defined
        but will most likely be one of the following:
            * xarray Dataset
            * netCDF4-python Dataset
        """
        if (...):
            return True
    ...

and in your package's setup.py, include the following in your setup() object:

setup(
    ...
    entry_points = {
        'gridded.grid_adapters': [
            'someGridAdapter = python.package.module:SomeGridAdapter'
        ]
    }
    ...

The API which a GridAdapter must conform to to be compatible with gridded is still in development. Check back soon!
