New issue 222: setenv with generated environments require unwanted settings
https://bitbucket.org/hpk42/tox/issue/222/setenv-with-generated-environments-require
Barry Warsaw:
Here is a my tox.ini file:
```
[tox]
envlist = py27,py34,coverage-{py27,py34},fast-{py27,py34}
recreate = True
[coverage]
rcfile = {toxinidir}/{envname}.ini
rc = --rcfile={[coverage]rcfile}
dir = --directory={envname}
setenv =
coverage: COVERAGE_PROCESS_START={[coverage]rcfile}
coverage: COVERAGE_OPTIONS="-p"
coverage: COVERAGE_FILE={toxinidir}/.coverage
[testenv]
commands =
py27,py34: python -m nose2 -v
coverage: python /usr/bin/python3-coverage run {[coverage]rc} -m nose2 -v
coverage: python3-coverage combine {[coverage]rc}
coverage: python3-coverage html {[coverage]rc} {[coverage]dir}
sitepackages = True
usedevelop = True
whitelist_externals = python3-coverage
setenv =
fast: SKIP_SLOW_TESTS=1
py34,py27: SKIP_SLOW_TESTS=0
```
Then:
```
% tox -l
py27
py34
coverage-py27
coverage-py34
fast-py27
fast-py34
```
However, if the line ```py34,py27: SKIP_SLOW_TESTS=0``` is omitted, then I get
a traceback:
```
% tox -l
