Support backticks within deps #5

Open jayvdb opened 5 years ago

jayvdb commented 5 years ago

It should be straight forward to add backticks within deps, and doesnt present any conflict with existing syntax as backticks are invalid requirements.txt syntax.

So this works in at least tox 3.8+

[testenv:deps]
setenv =
  DEPS=distro
deps =
  {env:DEPS}
commands =
  distro --help

However if setenv of DEPS uses backticks, installdeps fails because it occurs before the backticks handling which is done later in the hook tox_runtest_pre.

So a bit of re-structure is needed to use hook tox_testenv_install_deps to perform the backtick handling sooner. Using the earlier hook tox_testenv_create might also be possible. Removing the backticks asap is very likely to be better for interoperability with other tox plugins.
