Question about environment.yml

Hello @FlorianWilhelm, thank you very much for the handcrafted template! Very useful specially for people that still don’t have a preferred workflow for dealing with data, like me.

After generating a new project with pyscaffoldext-dsproject I was wondering what would be the advantages of having all the requirements listed in the environment.yml instead of installing the project itself in editable mode…

For example, what would be the disadvantages of doing:

@@src/pyscaffoldext/dsproject/templates/environment_yml.template:23@@
  - pip:
     # add here only pip-packages that are not available in conda/conda-forge! E.g.:
     - optuna
+    - -e .[testing]
+    - -r docs/requirments.txt
  # for development only (could also be kept in a separate environment file)
  - jupyterlab
- - pytest
- - pytest-cov
  - tox
  - pre_commit
  - nbdime
  - nbstripout
-  - sphinx
-  - recommonmark

Yes, exactly. Everything works as long as you use conda versions of special packages like virtualenv, ipython, etc. and since tox then uses the patched version of virtualenv everything works as expected. This is why I added those packages to environment.yml.
