Closes#1329.
## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
Mentions use of seed packages during `uv venv --seed`, and clarifies the
divergence in behavior when using Python 3.12+.
## Test Plan

Moves `--from` to a hidden argument — we allow it still but we validate
that it is compatible with whatever is passed to `uv tool install
<package>`. The positional package can now be a full specification,
allowing things like `uv tool install black==24.2.0`.
## Summary
- Adds a `--extra` flag to `uv add` that allows activating extras
without the PEP508 syntax.
- `uv add` now errors if the update is ambiguous (e.g. the dependency is
present twice with different markers)
- `uv add` is smarter about updates. For example, `uv add flask==3.0.0`
followed by `uv add flask --extra dotenv` preserves the previous version
specifier.
Resolves https://github.com/astral-sh/uv/issues/4419.
Adds detection of existing entry points, avoiding clobbering entry
points that were installed by another tool. If we see any existing entry
point collisions, we'll stop instead of overwriting them. The `--force`
flag can be used to opt-in to overwriting the files; we can't use `-f`
because it's taken by `--find-links` which is silly. The `--force` flag
also implies replacing a tool previously installed by uv (the
environment is rebuilt).
Similarly, #4504 adds support for reinstalls that _will not_ clobber
entry points managed by other tools.
## Summary
If the package _isn't_ marked as `workspace = true`, locking will fail
given:
```rust
let workspace_package_declared =
// We require that when you use a package that's part of the workspace, ...
!workspace.packages().contains_key(&requirement.name)
// ... it must be declared as a workspace dependency (`workspace = true`), ...
|| matches!(
source,
Some(Source::Workspace {
// By using toml, we technically support `workspace = false`.
workspace: true,
..
})
)
// ... except for recursive self-inclusion (extras that activate other extras), e.g.
// `framework[machine_learning]` depends on `framework[cuda]`.
|| &requirement.name == project_name;
if !workspace_package_declared {
return Err(LoweringError::UndeclaredWorkspacePackage);
}
```
Closes https://github.com/astral-sh/uv/issues/4552.
This is the minimal "working" implementation. In summary, we:
- Resolve the requested requirements
- Create an environment at `$UV_STATE_DIR/tools/$name`
- Inspect the `dist-info` for the main requirement to determine its
entry points scripts
- Link the entry points from a user-executable directory
(`$XDG_BIN_HOME`) to the environment bin
- Create an entry at `$UV_STATE_DIR/tools/tools.toml` tracking the
user's request
The idea with `tools.toml` is that it allows us to perform upgrades and
syncs, retaining the original user request (similar to declarations in a
`pyproject.toml`). I imagine using a similar schema in the
`pyproject.toml` in the future if/when we add project-levle tools. I'm
also considering exposing `tools.toml` in the standard uv configuration
directory instead of the state directory, but it seems nice to tuck it
away for now while we iterate on it. Installing a tool won't perform a
sync of other tool environments, we'll probably have an explicit `uv
tool sync` command for that?
I've split out todos into follow-up pull requests:
- #4509 (failing on Windows)
- #4501
- #4504Closes#4485
## Summary
This is an intermediary change in enabling universal resolution for
`requirements.txt` files. To start, we need to be able to preserve
markers in the `requirements.txt` output _and_ propagate those markers,
such that if you have a dependency that's only included with a given
marker, the transitive dependencies respect that marker too.
Closes#1429.

## Summary
Resolves https://github.com/astral-sh/uv/issues/4439 partially.
Implements for `uv pip tree`:
- `--no-dedupe` flag, similar to `cargo tree --no-dedupe` .
- denote dependency cycles with `(#)` and add a footnote if there's a
cycle (using `(*)` would require keeping track of the cycle state, so
opted to do this instead).
<!-- What's the purpose of the change? What does it do, and why? -->
## Test Plan
The existing tests pass + added a couple of tests to validate
`--no-dedupe` behavior.
<!-- How was it tested? -->
## Summary
This PR moves all the CLI code into its own crate, separate from the
`uv` crate. The `uv` crate is iterated on frequently, and the CLI code
comprises a significant portion of it but rarely changes. Removing the
CLI code reduces the `uv` crate size from 1.4MiB to 1.0MiB.
