Using mamba with pyproject.toml?

[asmith26]

Hi there,

I'm wondering if I can manage my mamba env using pyproject.toml. In particular, I'm using pyproject.toml for managing all my repo/package configuration (e.g. black/linting config), and was wondering if I might be able to do some things like:

mamba create -f pyproject.toml
mamba update -f pyproject.toml
mamba install -e .
# nice to have: things like building a python or conda/mamba package with mamba using pyproject.toml

Many thanks for any help, and for this amazing lib! :)

Would that not essentially be an alias for something like mamba install pip && mamba run pip install -e .?

Great thought thanks @wouterzwerink. That command does work for pip dependencies - what I'm wondering about is being able to install conda/mamba dependencies directly from pyproject.toml (e.g. nodejs).

I am also interested in using mamba with pyproject.toml, ideally by replacing environment.yml entirely. I've proposed a way for conda dependencies to be differentiated from pypi ones here: conda/conda#10633 (comment).
