## Summary
If you pass a named index via the CLI, you can now reference it as a
named source. This required some surprisingly large refactors, since we
now need to be able to track whether a given index was provided on the
CLI vs. elsewhere (since, e.g., we don't want users to be able to
reference named indexes defined in global configuration).
Closes https://github.com/astral-sh/uv/issues/7899.
## Summary
The behavior is as follows:
- If you provide `--index` or `--default-index` on the command-line, we
add those indexes to the `pyproject.toml` (with names, if provided, as
in `--index pytorch=https://download.pytorch.org/whl/cu121`.
- If you provide `--index-url` or `--default-index`, we warn, but don't
add the indexes to the file. (This seems wrong -- why not add them?)
- If you provide an index with a name or URL that already exists, we
remove that entry, and add the new index to the top of the list (since
it now has highest priority).
- If you provide a `--default-index`, and an index already has `default
= true`, we remove that entry, since it won't be used anymore.
We do _not_ pin packages to specific indexes yet.
## Summary
This PR adds a first-class API for defining registry indexes, beyond our
existing `--index-url` and `--extra-index-url` setup.
Specifically, you now define indexes like so in a `uv.toml` or
`pyproject.toml` file:
```toml
[[tool.uv.index]]
name = "pytorch"
url = "https://download.pytorch.org/whl/cu121"
```
You can also provide indexes via `--index` and `UV_INDEX`, and override
the default index with `--default-index` and `UV_DEFAULT_INDEX`.
### Index priority
Indexes are prioritized in the order in which they're defined, such that
the first-defined index has highest priority.
Indexes are also inherited from parent configuration (e.g., the
user-level `uv.toml`), but are placed after any indexes in the current
project, matching our semantics for other array-based configuration
values.
You can mix `--index` and `--default-index` with the legacy
`--index-url` and `--extra-index-url` settings; the latter two are
merely treated as unnamed `[[tool.uv.index]]` entries.
### Index pinning
If an index includes a name (which is optional), it can then be
referenced via `tool.uv.sources`:
```toml
[[tool.uv.index]]
name = "pytorch"
url = "https://download.pytorch.org/whl/cu121"
[tool.uv.sources]
torch = { index = "pytorch" }
```
If an index is marked as `explicit = true`, it can _only_ be used via
such references, and will never be searched implicitly:
```toml
[[tool.uv.index]]
name = "pytorch"
url = "https://download.pytorch.org/whl/cu121"
explicit = true
[tool.uv.sources]
torch = { index = "pytorch" }
```
Indexes defined outside of the current project (e.g., in the user-level
`uv.toml`) can _not_ be explicitly selected.
(As of now, we only support using a single index for a given
`tool.uv.sources` definition.)
### Default index
By default, we include PyPI as the default index. This remains true even
if the user defines a `[[tool.uv.index]]` -- PyPI is still used as a
fallback. You can mark an index as `default = true` to (1) disable the
use of PyPI, and (2) bump it to the bottom of the prioritized list, such
that it's used only if a package does not exist on a prior index:
```toml
[[tool.uv.index]]
name = "pytorch"
url = "https://download.pytorch.org/whl/cu121"
default = true
```
### Name reuse
If a name is reused, the higher-priority index with that name is used,
while the lower-priority indexes are ignored entirely.
For example, given:
```toml
[[tool.uv.index]]
name = "pytorch"
url = "https://download.pytorch.org/whl/cu121"
[[tool.uv.index]]
name = "pytorch"
url = "https://test.pypi.org/simple"
```
The `https://test.pypi.org/simple` index would be ignored entirely,
since it's lower-priority than `https://download.pytorch.org/whl/cu121`
but shares the same name.
Closes#171.
## Future work
- Users should be able to provide authentication for named indexes via
environment variables.
- `uv add` should automatically write `--index` entries to the
`pyproject.toml` file.
- Users should be able to provide multiple indexes for a given package,
stratified by platform:
```toml
[tool.uv.sources]
torch = [
{ index = "cpu", markers = "sys_platform == 'darwin'" },
{ index = "gpu", markers = "sys_platform != 'darwin'" },
]
```
- Users should be able to specify a proxy URL for a given index, to
avoid writing user-specific URLs to a lockfile:
```toml
[[tool.uv.index]]
name = "test"
url = "https://private.org/simple"
proxy = "http://<omitted>/pypi/simple"
```
## Summary
This PR declares and documents all environment variables that are used
in one way or another in `uv`, either internally, or externally, or
transitively under a common struct.
I think over time as uv has grown there's been many environment
variables introduced. Its harder to know which ones exists, which ones
are missing, what they're used for, or where are they used across the
code. The docs only documents a handful of them, for others you'd have
to dive into the code and inspect across crates to know which crates
they're used on or where they're relevant.
This PR is a starting attempt to unify them, make it easier to discover
which ones we have, and maybe unlock future posibilities in automating
generating documentation for them.
I think we can split out into multiple structs later to better organize,
but given the high influx of PR's and possibly new environment variables
introduced/re-used, it would be hard to try to organize them all now
into their proper namespaced struct while this is all happening given
merge conflicts and/or keeping up to date.
I don't think this has any impact on performance as they all should
still be inlined, although it may affect local build times on changes to
the environment vars as more crates would likely need a rebuild. Lastly,
some of them are declared but not used in the code, for example those in
`build.rs`. I left them declared because I still think it's useful to at
least have a reference.
Did I miss any? Are their initial docs cohesive?
Note, `uv-static` is a terrible name for a new crate, thoughts? Others
considered `uv-vars`, `uv-consts`.
## Test Plan
Existing tests
As per
https://matklad.github.io/2021/02/27/delete-cargo-integration-tests.html
Before that, there were 91 separate integration tests binary.
(As discussed on Discord — I've done the `uv` crate, there's still a few
more commits coming before this is mergeable, and I want to see how it
performs in CI and locally).
This is to address my own issue #7908
## Summary
This change makes use of the `clap` value_delimiter parser to populate
the `with` `Vec<String>` which currently can either only be empty or
with 1 value for each `--with` flag.
This makes use of the current code structure but allows for multiple
arguments with a single `--with` flag.
<!-- What's the purpose of the change? What does it do, and why? -->
## Test Plan
Can be tested with the following CLI:
```bash
target/debug/uv tool run --with numpy,polars,matplotlib ipython -c "import numpy;import polars;import matplotlib;"
```
And former behavior of multiple `--with` flags are kept
```bash
target/debug/uv tool run --with numpy --with polars --with matplotlib ipython -c "import numpy;import polars;import matplotlib;"
```

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
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.

## Summary
Closes#7841. If there are other env vars that would also benefit from
this value parser, please let me know and I can add them to this PR.
## Test Plan
When running the same example from the linked issue, it now works:
```
UV_PYTHON= cargo run -- init x
Compiling ...
Finished `dev` profile [unoptimized + debuginfo] target(s) in 29.06s
Running `target/debug/uv init x`
Initialized project `x` at `/Users/krishnanchandra/Projects/uv/x`
```
## 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
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
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!

This PR adds support for upgrading the build environment of tools with
the addition of a ```--python``` argument to ```uv upgrade```, as
specified in #7471.
Some things to note:
- I added support for individual packages — I didn't think there was a
good reason for ```--python``` to only apply to all packages
- Upgrading with ```--python``` also upgrades the package itself — I
think this is fair as if a user wants to _strictly_ switch the version
of Python being used to build a tool's environment they can use ```uv
install```. This behavior can of course be modified if others don't
agree!
Closes https://github.com/astral-sh/uv/issues/6297.
Closes https://github.com/astral-sh/uv/issues/7471.
## Summary
`uv run --project ./path/to/project` now uses the provided directory as
the starting point for any file discovery. However, relative paths are
still resolved relative to the current working directory.

## Summary
Because a problem was found with Powershell and combining the generated
completion scripts for uv and uvx, let's try separating uv and uvx
command completion scripts.
The generated powershell script template can be seen in clap_complete
source, and it starts with `using` directives, which makes it impossible
(apparently) to concatenate two of those script outputs.
As a side effect, this is available under `uv tool run
--generate-shell-completion` too.
Fixes#7482
## Test Plan
- `eval "$(cargo run --bin uvx -- --generate-shell-completion bash)"`
- Test Powershell
## Summary
This PR enables users to provide pre-defined static metadata for
dependencies. It's intended for situations in which the user depends on
a package that does _not_ declare static metadata (e.g., a
`setup.py`-only sdist), and that is expensive to build or even cannot be
built on some architectures. For example, you might have a Linux-only
dependency that can't be built on ARM -- but we need to build that
package in order to generate the lockfile. By providing static metadata,
the user can instruct uv to avoid building that package at all.
For example, to override all `anyio` versions:
```toml
[project]
name = "project"
version = "0.1.0"
requires-python = ">=3.12"
dependencies = ["anyio"]
[[tool.uv.dependency-metadata]]
name = "anyio"
requires-dist = ["iniconfig"]
```
Or, to override a specific version:
```toml
[project]
name = "project"
version = "0.1.0"
requires-python = ">=3.12"
dependencies = ["anyio"]
[[tool.uv.dependency-metadata]]
name = "anyio"
version = "3.7.0"
requires-dist = ["iniconfig"]
```
The current implementation uses `Metadata23` directly, so we adhere to
the exact schema expected internally and defined by the standards. Any
entries are treated similarly to overrides, in that we won't even look
for `anyio@3.7.0` metadata in the above example. (In a way, this also
enables #4422, since you could remove a dependency for a specific
package, though it's probably too unwieldy to use in practice, since
you'd need to redefine the _rest_ of the metadata, and do that for every
package that requires the package you want to omit.)
This is under-documented, since I want to get feedback on the core ideas
and names involved.
Closes https://github.com/astral-sh/uv/issues/7393.

Generate shell completion for uvx.
Create a `uvx` toplevel command just for completion by combining `uv
tool uvx` (hidden alias for `uv tool run`) with global arguments. This

arguments refer to global arguments in directives like conflicts with).

Summary
This pull request fixes a typo in the --build-constraints flag, which
should be singular (--build-constraint). This update ensures consistency
across the documentation and prevents potential confusion for users.
Closes#7315
## Test Plan
The change was verified by reviewing the relevant documentation files
where the flag is referenced. No functional code changes were made, so
no additional testing is required beyond confirming the documentation
update.
## Tested
The change was tested by visually inspecting the updated documentation
to confirm that the typo has been corrected
## Summary
Explicitly list the formats and extensions that uv supports, based on
[this
list](86ee8d2c01/crates/distribution-filename/src/extension.rs (L70-L77)).
Not a huge fan of adding the section in `concepts/resolution.md`, but I
did not find a better place. Alternatively we could maybe add a
dedicated page that shortly explains Python package types (wheels,
sdists), where such a section could live?
## Test Plan
Local run of the documentation.
