This was added in [#5426](https://github.com/astral-sh/uv/pull/5426)
The output that a python shell was started, but the command will only
print out the version because of the `--version` flag.
I think the section `Download Python versions as needed` should be
reverted back to `Download Python versions on demand` or something
similar because that's what the command will do. It will download the
given version if not already installed.

First off, congratulations on the 0.3 release! The PEP 723 standalone
scripts support is awesome, and I can already imagine a long tail of
little scripts of my own that would benefit from this functionality.
## Background
I really like the Deno CLI's support for running and installing remote
scripts.
```
deno run <url>
```
```
deno install --name foo <url>
```
I can see parallels with `uv run` and `uvx`. After mentioning this on
Discord, @zanieb suggested I could take a stab at a PR to implement
similar functionality for uv.
## Summary
This PR attempts to add support for executing remote standalone scripts
directly with `uv run`. While this is already possible by downloading
the script (i.e., via curl/wget) and then using uv run, having direct
support would be convenient.
The proposed functionality is:
```sh
uv run <url>
```
Another addition/alternative could be to support running scripts via
stdin:
```sh
curl -sL <url> | uv run -
```
But that is not implemented in this PR.
## Test Plan
I noticed that GitHub and `files.pythonhosted.org` URLs are used in some
of the tests. I've created a personal [GitHub
Gist](https://gist.github.com/manzt/cb24f3066c32983672025b04b9f98d1f)
with the example from PEP 723 for now to test this functionality.
~However, I couldn't figure out how to get the `with_snapshot` config
filter to filter out the tempfile path, so the test is currently
failing. Any assistance with this would be appreciated.~
## Notes
I'm not totally pleased with the implementation of this PR. I think it
would be better to handle the case earlier (and probably reuse the
cache), and avoid mutation, but since run command requires a local path
this was the simplest implementation I could come up with.
I know that performance is paramount with uv so I totally understand if
this requires a different approach or something more explicit to avoid
"inferring" the path. I'm just taking this as an opportunity to learn a
little more Rust and acquaint myself with the code base. cheers!

## Summary
These values can include spaces when passed on the command-line... Clap
doesn't give us a way to provide a value separator for _only_ an
environment variable (as is pip's behavior), so I think we're stuck
using comma-separated for here right now.
See, e.g., https://github.com/clap-rs/clap/discussions/3796.
Closes#8057.
## Summary
Renovate recently gained support for updating dependencies defined using
PEP 723 (https://github.com/renovatebot/renovate/pull/31266). Since uv
supports this format, I thought it could be nice to mention support for
it in the integrations documentation as well. I took the occasion to
make the page a bit more structured as well.
## Test Plan
Ran Renovate on https://github.com/mkniewallner/renovate-pep723, which
created https://github.com/mkniewallner/renovate-pep723/pull/2 that
updates a dependency defined using PEP 723. But I'll re-run some tests
again once the changes are released on Renovate cloud GitHub app just in
case.

## Summary
This PR adds the ability to list available scripts in the environment
when `uv run` is invoked without any arguments.
It somewhat mimics the behavior of `rye run` command
(See https://rye.astral.sh/guide/commands/run).
This is an attempt to fix#4024.
## Test Plan
I added test cases. The CI pipeline should pass.
### Manuel Tests
```shell
❯ uv run
Provide a command or script to invoke with `uv run <command>` or `uv run script.py`.
The following scripts are available:
normalizer
python
python3
python3.12
See `uv run --help` for more information.
```

Improve hints when using the simple index URL instead of the upload URL
in `uv publish`. This is the most common confusion when publishing, so
we give it some extra care and put it more centrally in the CLI help.
Fixes#7860

## Summary
This PR adds support for the `UV_FIND_LINKS` environment variable as an
alternative to the `--find-links` command-line option, as requested in
#1839.
## Test Plan
A unit test was added to validate that setting `UV_FIND_LINKS` provided
the same result as a link provided with the `--find-links` command-line
option.

## Summary
This is a trivial, one line documentation change that fixes the
following documentation bug.
The current documentation suggests this for adding a git dependency
```
# Add a git dependency
uv add requests --git https://github.com/psf/requests
```
Executing what is suggested with `uv` version `0.4.18` results in this
error message
```
uv add requests --git https://github.com/psf/requests
error: unexpected argument '--git' found
```
The working approach is to add the git depency like this:
```
uv add git+https://github.com/psf/requests
```
## Test Plan
I manually tested the command suggested currently in the guide against
my change.

## Summary
Create a function main as the default for a packaged app. Configure the
default executable as:
`example-packaged-app = "example_packaged_app:main"`
Which is often what you want - the executable has the same name as the
app.
The purpose is to more often hit what the user wants, so they don't have
to even rename the command to start developing.
## Test Plan
- existing tests are updated
## Summary
This PR enables users to provide multiple source entries in
`tool.uv.sources`, e.g.:
```toml
[tool.uv.sources]
httpx = [
{ git = "https://github.com/encode/httpx", tag = "0.27.2", marker = "sys_platform == 'darwin'" },
{ git = "https://github.com/encode/httpx", tag = "0.24.1", marker = "sys_platform == 'linux'" },
]
```
The implementation is relatively straightforward: when we lower the
requirement, we now return an iterator rather than a single requirement.
In other words, the above is transformed into two requirements:
```txt
httpx @ git+https://github.com/encode/httpx@0.27.2 ; sys_platform == 'darwin'
httpx @ git+https://github.com/encode/httpx@0.24.1 ; sys_platform == 'linux'
```
We verify (at deserialization time) that the markers are
non-overlapping.
Closes https://github.com/astral-sh/uv/issues/3397.

## Summary
I have a workflow where I want use `uv` as a dependency solver only, and
manage my environments with external tooling (Nix).
## Test Plan
Manually tested. Automated testing seems excessive for such a trivial
change.
## Problems
It's still not as useful as I'd like it to be.
`uv` uncondtionally creates a virtual environment, something I would
expect that `--no-sync` should disable.
This looks a bit more tricky to achieve and I'm not sure about how to
best structure it.
## Summary
This is another attempt using `module: bool` instead of `module:
Option<String>` following #7322.
The original PR can't be reopened after a force-push to the branch, I've
created this new PR.
Resolves#6638
## Summary
Resolves#7705
## Test Plan
`cargo test` and tested locally.
The snapshots were unstable due to the packages being built in a
non-deterministic order, so I used the quiet flag to suppress the
output.
Another question is whether we should label the build output to indicate
which package it belongs to?
## Summary
It was all too easy to just copy the non-qualified name of the Docker
images and wonder why they couldn't be found – well, because they're on
`ghcr.io`, and you need to read the prose before the list to figure that
out.
## Test Plan
No plan.
## Summary
Similiar to `cargo init --vcs <VCS>`, this PR adds the `--vcs <VCS>`
flag for `uv init`, allowing to create a version control system during
initialization. By default, `uv init` will create a Git repository if
the `--vcs` flag is not provided. Use `--vcs none` to disable this
feature.
Currently, only Git is supported. While Cargo also supports hg, pijul,
and fossil, this initial PR only includes Git. We can add more later if
there are any user requests.

This PR adds support for ```uv init --script```, as defined in issue
#7402 (started working on this before I saw jbvsmo's PR). Wanted to
highlight a few decisions I made that differ from the existing PR:
1. ```--script``` takes a path, instead of a path/name. This potentially
leads to a little ambiguity (I can certainly elaborate in the docs,
lmk!), but strictly allowing ```uv init --script path/to/script.py```
felt a little more natural than allowing for ```uv init --script path/to
--name script.py``` (which I also thought would prompt more questions
for users, such as should the name include the .py extension?)
2. The request is processed immediately in the ```init``` method,
sharing logic in resolving which python version to use with ```uv add
--script```. This made more sense to me — since scripts are meant to
operate in isolation, they shouldn't consider the context of an
encompassing package should one exist (I also think this decision makes
the relative codepaths for scripts/packages easier to follow).
3. No readme — readme felt a little excessive for a script, but I can of
course add it in!
