## Summary
Replace `--frozen` with `--locked` in Docker integration guide.
`--locked` additionally validates that `uv.lock` is "fresh"/up to date,
which will catch errors if the user accidentally updated
`pyproject.toml` but did not run `uv lock` before building the
container. This is probably a better/safer default to recommend to users
to avoid surprising/incorrect behavior.
## References
- External guides already recommend using `--locked` instead of
`--frozen`
- https://hynek.me/articles/docker-uv/
- @zanieb seemed to indicate they might agree that `--locked` would be
better to avoid surprises
- https://github.com/astral-sh/uv/issues/10793#issuecomment-2743956736
## Test Plan
Used `--locked` in `uv` Python projects using Docker and validated that
it works as expected.
## Summary
Adds note to docs about PEP 751 to documentation as discussed in #12641
## Test Plan

## Summary
Add an option to overwrite the list of available Python downloads from a
local JSON file by using the environment variable
`UV_PYTHON_DOWNLOADS_JSON_URL`
as an experimental support for providing custom sources for Python
distribution binaries #8015
related #10203
I probably should make the JSON to be fetched from a remote URL instead
of a local file.
please let me know what you think and I will modify the code
accordingly.

@jtfmumm mentioned a desire for this. I'm not sure how we should do
this. I kind of want to change this to something like...
```
$ uv python find
CPython 3.13 @ <path>
$ uv python find --only-path
<path>
$ uv python find --short
<path>
$ uv python find --only-version
3.13
```
The change in defaults would be breaking though.
## Summary
Fix a suggestion in the docs on configs through environment variables,
which lists an option value that doesn't appear to exist.
The description implies that `unsafe-best-match` was intended here.
## Test Plan
Verified by providing `unsafe-any-match` as a parameter to `uv`. It
didn't error, but appeared to use the `first-index` strategy instead.
The value I changed it to behaves as described by the documentation.
Fix broken grammar and hl_lines.

## Summary
I only changed the location of where the fish completions get sent, from
`~/.config/fish/config.fish` to `~/.config/fish/completions/uv.fish` and
`~/.config/fish/completions/uvx.fish` respectively
## Test Plan
I have tested and putting the completions in those paths works fine and
complies with the fish docs. Also keeps your `config.fish` clean
### edit:
refer to
https://fishshell.com/docs/current/completions.html#where-to-put-completions
> This wide search may be confusing. If you are unsure, your completions
probably belong in `~/.config/fish/completions`.
Adding dependency trace/parent comments ("via ...") to the export
command output.
This is a similar behavior to the pip compile output.
#### Note to the eager reviewer:
First of all - thanks!
Secondly, this is still a very rough draft. These are the first lines of
code I've ever written in Rust. This is still mostly an educational/fun
exercise for myself. If opening a Draft PR is creating too much noise -
I apologize and I will close it until it is ready.
## Summary
Resolves#7777
## Test Plan
- [X] manual command execution
- [x] update expected output in tests

The idea here is that we introduce a new stdout_important method for
things that want to care about the difference between "quiet" and
"silent".
This PR is WIP because it has no actual uses of stdout_important, and we
should have at least one before landing this. Perhaps someone has a
suggestion for commands that would really benefit from this distinction?
Fixes#10431
## Summary
This PR extends `[[tool.uv.index]]` to support `--find-links`-style
"flat" indexes, so that users can point to such indexes without using
`--find-links` _and_ get access to the full functionality of
`[[tool.uv.index]]` (e.g., they can now pin packages to
`--find-links`-style indexes).
Note that, at present, `--find-links` indexes actually have some quirky
behavior, in that we combine them into a single entity and then merge
the discovered distributions into each Simple API-style index. The
motivation here, IIRC, was to match pip's behavior quite closely. I'm
interested in _removing_ that behavior, but it'd be breaking (and may
also be inconvenient for some use-cases). So, the behavior for indexes
passed in via `--find-links` remains completely unchanged. However,
`[[tool.uv.index]]` entries with `format = "flat"` are now treated
identically to those defined with `format = "simple"` (the default), in
that we stop after we find the first-matching index, etc.
Closes https://github.com/astral-sh/uv/issues/11634.
## Summary
This fixes https://github.com/astral-sh/uv/issues/12426 which helps use
a more accurate arg name in the help output.
## Test Plan
I didn't test it locally, @charliermarsh gave me guidance on what to
change so I looked around that file for another example of `value_name`
and repeated what I saw. I kept it formatted to 1 line based on it not
being a long line. The other example of `value_name` had everything on
separate lines because there were a bunch of parameters passed in.

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)

## Summary
Fixes#12334
<!-- What's the purpose of the change? What does it do, and why? -->
## Test Plan
<!-- How was it tested? -->
## Summary
Resolves#11794.
When `uv python find` is given a `--script` option, either the existing
environment for that script or the Python executable that would be used
to create it will be returned. If neither are found, the command exits
with exit code 1.
`--script` is incompatible with all other options to the same command.
## Test Plan
Unit tests.
## Summary
This is a prototype that I'm considering shipping under `--preview`,
based on [`light-the-torch`](https://github.com/pmeier/light-the-torch).
`light-the-torch` patches pip to pull PyTorch packages from the PyTorch
indexes automatically. And, in particular, `light-the-torch` will query
the installed CUDA drivers to determine which indexes are compatible
with your system.
This PR implements equivalent behavior under `--torch-backend auto`,
though you can also set `--torch-backend cpu`, etc. for convenience.
When enabled, the registry client will fetch from the appropriate
PyTorch index when it sees a package from the PyTorch ecosystem (and
ignore any other configured indexes, _unless_ the package is explicitly
pinned to a different index).
Right now, this is only implemented in the `uv pip` CLI, since it
doesn't quite fit into the lockfile APIs given that it relies on feature
detection on the currently-running machine.
## Test Plan
On macOS, you can test this with (e.g.):
```shell
UV_TORCH_BACKEND=auto UV_CUDA_DRIVER_VERSION=450.80.2 cargo run \
pip install torch --python-platform linux --python-version 3.12
```
On a GPU-enabled EC2 machine:
```shell
ubuntu@ip-172-31-47-149:~/uv$ UV_TORCH_BACKEND=auto cargo run pip install torch -v

## 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.
