## Summary
* Upgrade the rust toolchain to 1.85.0. This does not increase the MSRV.
* Update windows trampoline to 1.86 nightly beta (previously in 1.85
nightly beta).
## Test Plan
Existing tests
According to the [UV
documentation](https://docs.astral.sh/uv/configuration/files/#env), the
UV_ENV_FILE environment variable should support multiple .env files,
separated by spaces. However, when I tried using this feature in my
repository, it didn’t work as expected.
To investigate, I checked the UV repository for relevant tests and found
`run_with_multiple_env_files`.
This test asserts the following `error: No environment file found at:
.env1 .env2.`
This discrepancy could indicate either a mismatch between the
documentation and the implementation or a bug in the code.
I decided to fix the issue in the code since the ability to pass
multiple `.env` files is a valuable feature.
If my fix isn’t appropriate, I’d be happy to make any necessary
adjustments.

Closes#11285
Closes https://github.com/astral-sh/uv/pull/11437
This changes `-p` from an alias of `--python-version` to `--python`
while retaining backwards compatibility for `--python-version`-like
fallback behavior when the requested version, e.g., `-p 3.12`, cannot be
found.
This was initially implemented with a hidden `--python-legacy` flag
which allows us to special case the short `-p` flag — unlike the
implementation in #11437. However, after further discussion, we decided
the behavior difference between `-p` and `--python` would be confusing
so now `-p` is an alias for `--python` and `--python` is special-cased
when a version is used.
Additionally, we now respect the `UV_PYTHON` environment variable, but
it is ignored when `--python-version` is set. If you want different
`--python-version` and `--python` values, you must do so explicitly. I
considered banning this, but it is valid for e.g. `--python pypy
--python-version 3.12`
Unlike https://github.com/astral-sh/uv/pull/10222, this does not respect
`UV_PYTHON` in `uv python uninstall` (continuing to require an explicit
target there) which I think is simpler and matches our `.python-version`
file behavior.

## Summary
Handle potential infinite recursion if `uv run` recursively invokes `uv
run`. This can happen if the shebang line of a script includes `uv run`,
but does not pass `--script`.
Handled by adding a new environment variable `UV_RUN_RECURSION_DEPTH`,
which contains a counter of the number of times that uv run has been
recursively invoked. If unset, it defaults to zero, and each time uv run
starts a subprocess we increment the counter, erroring if the value is
greater than a configurable (but not currently exposed or documented)
threshold.
Closes https://github.com/astral-sh/uv/issues/11220.
## Test Plan
I've added a snapshot test to `uv/crates/uv/tests/it/run` that tests the
end-to-end recursion detection flow. I've currently made it a unix-only
test because I'm not sure offhand how uv run will interact with shebang
lines on windows.

## Summary
The environment is located at a stable path within the cache, based on
the script's absolute path.
If a lockfile exists for the script, then we use our standard lockfile
semantics (i.e., update the lockfile if necessary, etc.); if not, we
just do a `uv pip sync` (roughly).
Example usage:
```
❯ uv init --script hello.py
Initialized script at `hello.py`
❯ uv add --script hello.py requests
Updated `hello.py`
❯ cargo run sync --script hello.py
Using script environment at: /Users/crmarsh/.cache/uv/environments-v1/hello-84e289fe3f6241a0

## Summary
This adds `NO_BINARY` and `NO_BINARY_PACKAGE` environment variables to
the uv CLI, allowing the user to specify packages to build from source
using environment variables. Its not a complete fix for #4291 as it does
not handle the `pip` subcommand.
## Test Plan
This was tested by running `uv sync` with various `UV_NO_BINARY` and
`UV_NO_BINARY_PACKAGE` environment variables set and checking that the
correct set of packages were compiled rather than taken from pre-built
wheels.

This is a rewrite of the groups subsystem to have more clear semantics,
and some adjustments to the CLI flag constraints. In doing so, the
following bugs are fixed:
* `--no-default-groups --no-group foo` is no longer needlessly rejected
* `--all-groups --no-default-groups` now correctly evaluates to
`--all-groups` where previously it was erroneously being interpretted as
just `--no-default-groups`
* `--all-groups --only-dev` is now illegal, where previously it was
accepted and mishandled, as if it was a mythical `--only-all-groups`
flag
Fixes#10890Closes#10891
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.
uv-install-wheel had the logic for laying out the installation and for
linking a directory in the same module. We split them up to isolate each
module's logic and tighten the crate's interface to only expose top
level members.
No logic changes, only moving code around.
## Summary
Fixes a recurring typo.
## Details
There's a typo appearing in a particular sentence...
> Ignore package dependencies, instead only add those packages
explicitly listed on the command line to the resulting **the**
requirements file.
... used in:
* `crates/uv-cli/src/lib.rs`
* `crates/uv-settings-src-settings.rs`
* `docs/reference/settings.md`
* `uv.schem.json`
Docs, comments and a CLI command description seem affected.
This PR fixes it.

I'm sorry, but I was writing some new content here and the inconsistent
wrapping was very hard to maintain and I didn't want to muddy the diff
there with reflowing.
I don't think we need to be strict about the reflow (I'm not sure we
even can be) but some of these were very far off from our typical wrap
length.
We'll probably end up shipping but we were moving ahead with this on the
basis that pip may not even ship this, so let's play it safe and wait
for a bit.
Ultimately this is a lot of settings plumbing and a couple minor pieces
of Actual Logic (which are so simple I have to assume there's something
missing, but maybe not!).
Note this "needlessly" use DevDependencyGroup since it costs nothing, is
more futureproof, and lets us maintain one primary interface (we just
pass `false` for all the dev arguments).
Fixes#8590Fixes#8969
## Summary
Relates to #10273.
This doesn't solve what is highlighted in
https://github.com/astral-sh/uv/issues/10273#issuecomment-2569515066,
but I believe this is still an improvement for users not setting
`upgrade = true` in `[tool.uv]`.
## Test Plan
Ran commands locally:
```shell
$ cargo run --quiet -- lock --locked --upgrade
error: the argument '--check' cannot be used with '--upgrade'
Usage: uv lock --check
For more information, try '--help'.

## Summary
I use `uv` for automation on remote hosts and it would be useful to have
it be able to tell me the supported versions of python (for the remote
machine) in a machine readable manner so I do not need to parse `uv
python list`.
This change adds `--format (json|text)` to `uv python list` to make it's
output machine readable
Loosely related:
- https://github.com/astral-sh/uv/issues/411
## Test Plan
Manually tested via
```
# quick inspection without pretty print
cargo run -- python list --format json
```
### Short example of output (trimmed down)
Cmd: `cargo run -- python list --format json | jq '.[:2]'`
```json

#8061 incorrectly claims to change the delimiter for `UV_FIND_LINKS`
from spaces to commas. In reality, it prevents `UV_FIND_LINKS` from
being split. This commit fixes that.
## Summary
You can now run `uv tree --script main.py` to show the dependency tree
for a given script. If a lockfile doesn't exist, it will create one.
Closes https://github.com/astral-sh/uv/issues/7328.
## Summary
`uv add --script main.py anyio` will now update the lockfile, _if_ it
already exists. (If no such lockfile exists, the behavior is unchanged.)
## Summary
This PR adds `ls` alias to `uv {tool, python, pip} list` for
convenience.
Not sure if folks previously discussed this or have any opinion on
having aliases – but I have a muscle memory for `ls` for listing things
in commands I'm using (like `docker images ls`, `zellij ls`, `helm ls`
etc.) and thought having `ls` alias for `list` command would be useful.
## Test Plan
I simply compiled `uv` and manually checked `./target/release/uv {tool,
python, pip} ls`.
## Summary
You can now run `uv lock --script main.py` to lock a given script
(though as of this PR, the script itself isn't used anywhere).
Closes https://github.com/astral-sh/uv/issues/6318.
## Summary
This allows, e.g., `uv remove flask[dotenv]` to remove `flask`. Like
`pip install` and `uv pip install`, the content after the package name
has no effect.
Closes https://github.com/astral-sh/uv/issues/9764.
## Summary
Closes#7913 by adding an optional `--description` argument to `uv init`
that fills the description field in the pyproject.toml with the supplied
arg value.
Updated `uv init` docs to describe this new optional argument.
<!-- What's the purpose of the change? What does it do, and why? -->
## Test Plan
Added snapshot tests in `uv/crates/uv/tests/it/init.rs` to test this
functionality.
<!-- How was it tested? -->

## Summary
`uv run --exact` will remove any unnecessary packages prior to running
the given command. (By default, `uv run` uses "inexact" semantics.)
