Can pants in future do third party dependency management like poetry does with `add` `remove` or `update` I suppose this won t generalize across multiple languages

We re definitely open to it But I agree it needs a little design work

Couldn t you use a poetry lock file and then use the poetry tooling for add remove update

Sort of Pants can t understand Poetry native lockfiles You could use `poetry export` but it has some limitations like not always working correctly Also we are likely soon going to switch to only accepting Pex lockfiles because they allow much better performance we know how to install the specific subset of the lockfile needed for a particular task Whereas non Pex lockfiles require us to first install the whole lockfile and then extract the subset of what s used

gt we are likely soon going to switch to only accepting Pex lockfiles This isn t 100 decided We still allow you to use non Pex lockfiles in requirements txt style which was an important escape hatch as we rolled out Pex lockfiles The Python ecosystem is huge so we expected lots of edge cases we didn t know about We ve now had Pex lockfiles for 3 months and they re working pretty well from what we can tell But we may want to keep the escape hatch Unclear

Yes Some tooling around managing deps would be immensely helpful But pants has more complexity to deal with than poetry Poetry expects dependencies defined in one `pyproject toml` and one poetry lock file and only one distribution wheel will result Pants has multiple resolves multiple distributions dependencies can be defined in requirements files BUILD files pipenv metadata or poetry metadata and eventually PEP 621 dependencies in `pyproject toml` So the semantics are a lot more complicated for pants
