## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
The PyTorch guide page has this, but it's missing from this example
(which is otherwise identical to the PyTorch guide page). I think it
would be helpful to include it here too.

Allows `uv python list <request>` to filter the installed list. I often
want this and it's not hard to add.
I tested the remote download filtering locally (#12381 is needed for
snapshot tests)
```
❯ cargo run -q -- python list --all-versions 3.13
cpython-3.13.2-macos-aarch64-none <download available>
cpython-3.13.1-macos-aarch64-none /opt/homebrew/opt/python@3.13/bin/python3.13 -> ../Frameworks/Python.framework/Versions/3.13/bin/python3.13
cpython-3.13.1-macos-aarch64-none <download available>
cpython-3.13.0-macos-aarch64-none /Users/zb/.local/share/uv/python/cpython-3.13.0-macos-aarch64-none/bin/python3.13
❯ cargo run -q -- python list --all-versions 3.13 --only-installed
cpython-3.13.1-macos-aarch64-none /opt/homebrew/opt/python@3.13/bin/python3.13 -> ../Frameworks/Python.framework/Versions/3.13/bin/python3.13

## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
The examples assume that the packages are in the project root directory.
However, they are nested inside `src`, and the commands in the examples
do not work as intended.
I could not find any related issues.
## Test Plan
<!-- How was it tested? -->
I tested it by executing the commands on my terminal - Linux and Windows
(PowerShell).

Currently, for users to specify at the command line whether to use
uv-managed or system Python interpreters, they use the
`--python-preference` parameter, which takes four possible values. This
is more complex than necessary since the normal case is to either say
"only managed" or "not managed". This PR hides the old
`--python-preference` parameter from help and documentation and adds two
new flags: `--managed-python` and `--no-managed-python` to capture the
"only managed" and "not managed" cases.
I have successfully tested this locally but currently cannot add
snapshot tests because of problems with distinguishing managed vs.
system interpreters in CI (and non-determinism when run on different
developers' machines). The `--python-preference` test in
`tool-install.rs` is currently ignored for this reason. See #5144 and
#7473.

## Summary
This has come up a few times, so it seems worth addressing. If you
migrate from a flat layout to a `src` layout or vice versa, we now
invalidate the package metadata.
Closes https://github.com/astral-sh/uv/issues/12047
## Summary
This ended up being more involved than expected. The gist is that we
setup all the packages we want to reinstall upfront (they're passed in
on the command-line); but at that point, we don't have names for all the
packages that the user has specified. (Consider, e.g., `uv pip install
.` -- we don't have a name for `.`, so we can't add it to the list of
`Reinstall` packages.)
Now, `Reinstall` also accepts paths, so we can augment `Reinstall` based
on the user-provided paths.
Closes#12038.
These changes add support for
```
uv python pin 3.12 --global
```
This adds the specified version to a `.python-version` file in the
user-level config directory. uv will now use the user-level version as a
fallback if no version is found in the project directory or its
ancestors.
Closes#4972

## Summary
The command `uv python find >=3.11` doesn't work . The version should be
quoted otherwise the terminal interprets the `>` and pipes output to a
file named `=3.11`. I've used single quotes as used on line 90 of this
file.
## Test Plan
Locally
## Summary
Follow up to https://github.com/astral-sh/uv/pull/11888 with added
support for uv tool run.
Changes
* Added functionality for running windows scripts in previous PR was
moved from run.rs to uv_shell::runnable.
* EXE was added as a supported type, this simplified integration across
both uv run and uvx while retaining a backwards compatible behavior and
properly prioritizing .exe over others. Name was adjusted to runnable as
a result to better represent intent.
## Test Plan
New tests added.
## Documentation
Added new documentation.
## Summary
In https://github.com/astral-sh/uv/issues/11998, a user is attempting to
vendor `pydantic-core`. But when they add `pydantic-core = { path =
"src/foo/vendor/pydantic-core" } `, we're installing it as a virtual
package, since `pydantic-core/pyproject.toml` contains `package =
false`.
This PR allows users to mark dependencies as "explicitly a package" or
"explicitly not a package" (i.e., virtual), as a workaround.
Closes https://github.com/astral-sh/uv/issues/11998.
## Summary
The current wording on the [caching
page](https://docs.astral.sh/uv/concepts/cache/#dynamic-metadata) makes
it sounds like defining `cache-keys` in a project adds to the metadata
considered when caching. However it actually replaces the metadata. So
copying the example using the git commit results in only considering the
git commit, not the pyproject.toml, which is likely not what is
typically desired.

I need to self-review this still.
Updates the "Locking and syncing" page to actually have content on
syncing — which was the original intent, the rest of this file was just
copied out of the "Projects" page when I split it into multiple pages.

Initially it seemed like `app.py` might be slightly more desirable but
people seem to overwhelmingly favour `main.py` as a good "generic" name.
Fixes#7782
## Summary
I followed the docs to install flash-attn with uv and got the following
issue
```uv sync
Resolved 27 packages in 12ms
× Failed to build `flash-attn==2.7.4.post1`
├─▶ The build backend returned an error
╰─▶ Call to `setuptools.build_meta:__legacy__.build_wheel` failed (exit status: 1)
[stderr]
Traceback (most recent call last):
File "<string>", line 8, in <module>
ModuleNotFoundError: No module named 'setuptools'
hint: This usually indicates a problem with the package or the build environment.
```
installing setuptools before running uv sync as done with torch helps
fix it.
## Test Plan
I tested locally before it failed to install, after it worked
I think `UV_PROJECT_ENVIRONMENT` is too complicated for use-cases where
the user wants to sync to the active environment. I don't see a
compelling reason not to make opt-in easier. I see a lot of questions
about how to deal with this warning in the issue tracker, but it seems
painful to collect them here for posterity.
A notable behavior here — we'll treat this as equivalent to
`UV_PROJECT_ENVIRONMENT` so... if you point us to a valid virtual
environment that needs to be recreated for some reason (e.g., new Python
version request), we'll happily delete it and start over.
We regularly get questions why `uv build` is missing certain files or
using the wrong build tag, when that's done by the build backend and
part of the build backend's docs. I tried to clarify this difference and
to redirect users to look at the tool's docs instead of wondering why
uv's docs don't explain that.

I'm not sure if this should go in the CLI reference or not? but here
seems like an okay start. I want to figure out a way to avoid repeating
this content.
## Summary
The docs did mention that you could set the `UV_PROJECT_ENVIRONMENT`
variable to point Uv to use the system Python environment (e.g. for use
in CI or Docker), but it did not document _how_.
