After installing, simply call tox2travis in a directory that contains a tox.ini file. A .travis.yml file will be generated.

tox2travis will be able to map environment names using tox's default environments to the correct python version on Travis automatically.

If an environment name does not match one of the default environments provided by tox, tox2travis will simply ignore it. To specify a python version for such environments, use the --fallback-python command line argument:

tox2travis --fallback-python pythonx.y

The value passed to the argument must be a valid basepython.

If environments specified in tox.ini use a basepython that can not be automatically mapped to one of the supported python versions on Travis, use the --custom-mapping command line argument:

tox2travis --custom-mapping <basepython> <travis-python>

Despite the name, tox2travis can also generate a configuration file for GitHub Actions. Simply call tox2travis --output=actions in a directory that contains a tox.ini file. A new file .github/workflows/tox.yml will be generated.
