what does it do?

It does not

• Format any other section beside tox/testenv:* (other than put this sections to the end of the file)

General

• boolean fields are normalized to true or false
• all fields are stripped of white space on both end
• values that contain a list are split one value per line (PR/merge friendly)
• indent multi-line values by four spaces, and start on new line
• substitutions within multi-line (excluding commands) are moved to the start of the list (order kept)

Ordering of sections

Applies the following section order:

1. tox
2. testenv
3. testenv:* - py/pypy envs are ordered in decreasing order by python version, then apply the order defined within envlist part of tox section, you can pin tox elements to the start by using the -p flag
4. any other section defined within the file

1. envlist - multi-line, start with py envs in decreasing python order, then same with pypy, then everything else
