tox-appveyor 0.1

This is a tiny Tox plugin to allow selecting 32-bit or 64-bit Python on AppVeyor Windows CI builds.

In your appveyor.yml file, specify the different builds like this:

environment:
  matrix:
    # Python 3.7, 64-bit
    - TOXENV: "py37"
      TOX_APPVEYOR_X64=1

    # Python 3.7, 32-bit
    - TOXENV: "py37"
      TOX_APPVEYOR_X64=0


# For the sections below, the Python version doesn't matter:
# tox will make an environment based on the environment variables.

install:
  - "build.cmd py -3.6 -m pip install wheel tox tox-appveyor"

test_script:
  - "build.cmd py -3.6 -m tox"
