uv: An extremely fast Python package and project manager, written in Rust

uv is almost perfect. my only pet peeve is updating dependencies. sometimes I just want to go "uv, bump all my dependencies to the as latest version as possible while respecting their constraints". I still haven't found an elegant way to do this, but I have written a script that parses pyproject.toml, removes the deps, and invokes `uv add --upgrade` with them.

other than that, it's invaluable to me, with the best features being uvx and PEP 723

Does `uv lock —upgrade` not do what you want?

Unfortunately, no. Only `uv.lock` gets updated, but the dependencies in `pyproject.toml` are frozen at their original constraints.

What I want is, if my project depends on `package1==0.4.0` and there are new versions of package1, for uv to try install the newer version. and to do that for a) all the deps, simultaneously, b) without me explicitly stating the dependencies in the command line since they're already written in the pyproject.toml. an `uv refresh` of sorts

Why not depend on package1>=0.4.0 rather than specifying an explicit version? Then uv will upgrade it to the latest version.

pyproject.toml is meant to encode the actual constraints for when your app will function correctly, not hardcode exact versions, which is what the lockfile is for.

Because then you don't get to use the new features in 0.5.0.

Though I do think with Python in particular it's probably better to manually upgrade when needed, rather than opportunistically require the latest, because Python can't handle two versions of the same package in one venv.

Then make your dependency package1>=0.4
