## Summary
This PR makes the behavior in https://github.com/astral-sh/uv/pull/9827
the default: we try to select the latest supported package version for
each supported Python version, but we still optimize for choosing fewer
versions when stratifying by platform.
However, you can opt out with `--fork-strategy fewest`.
Closes https://github.com/astral-sh/uv/issues/7190.
When publishing, we currently ask the user to set `--publish-url` to the
upload URL and `--check-url` to the simple index URL, or the equivalent
configuration keys. But that's redundant with the `[[tool.uv.index]]`
declaration. Instead, we extend `[[tool.uv.index]]` with a `publish-url`
entry and allow passing `uv publish --index <name>`.
`uv publish --index <name>` requires the `pyproject.toml` to be present
when publishing, unlike using `--publish-url ... --check-url ...` which
can be used e.g. in CI without a checkout step. `--index` also always
uses the check URL feature to aid upload consistency.
The documentation tries to explain both approaches together, which
overlap for the check URL feature.
Fixes#8864

## Summary
This change introduces the `UV_NO_INSTALLER_METADATA` environment
variable
as a way to opt out of the extra installer metadata files that `uv` is
creating.
This is important to achieve reproducible builds in distribution
packaging, allowing to replace usage of
[installer](https://pypi.org/project/installer) with `uv pip install`.
At the time of writing these files are:
- `uv_cache.json`
Contains timestamps which are non-reproducible.
These hashes also leak in to the `RECORD` file.
- `direct_url.json`
Contains the path to the installed wheel.
While not non-reproducible it's not required for distribution packaging.
- `INSTALLER`
Again, not non-reproducible, but of no value in distribution packaging.
## Test Plan
Automated test added.

## Summary
Aligns the description of `UV_NO_PROGRESS` with other env vars that also
have a related flag.
`--no-progress` is a "global option" and exists in every command.

- Adds a collapsible section for the project concept
- Splits the project concept document into several child documents.
- Moves the workspace and dependencies documents to under the project
section
- Adds a mkdocs plugin for redirects, so links to the moved documents
still work
I attempted to make the minimum required changes to the contents of the
documents here. There is a lot of room for improvement on the content of
each new child document. For review purposes, I want to do that work
separately. I'd prefer if the review focused on this structure and idea
rather than the content of the files.
I expect to do this to other documentation pages that would otherwise be
very nested.
The project concept landing page and nav (collapsed by default) looks
like this now:

Fixes#9164
Using clap's `default_value_t` makes the `flag` function unhappy, so
just set the default when we unwrap. Tested with no flags,
`--verify-hashes`, `--no-verify-hashes` and setting in uv.toml

## Summary
This PR pulls in https://github.com/astral-sh/uv/pull/8263 and
https://github.com/astral-sh/uv/pull/8463, which were originally merged
into the v0.5 tracking branch but can now be committed separately, as
we've made `.env` loading opt-in.
In summary:
- `.env` loading is now opt-in (`--env-file .env`).
- `.env` remains supported on `uv run`, so it's meant for providing
environment variables to the run command, rather than to uv itself.

## Summary
* Env docs now support anchors, which allows sending a link to someone
with a direct reference to an env var or cross-reference them in the
docs.
* Marked additional env vars as hidden from the docs due to their
internal use
* Updates some tests still using literals to use the static env vars
## Test Plan

## Summary
Resolves#8417
I've just begun learning procedural macros, so this PR is more of a
proof of concept. It's still a work in progress, and I welcome any
assistance or feedback.
I was following along the docs for this section and the index name
didn't match the example before it.

The changes in this commit introduce the `UV_NO_PROGRESS` environment
variable as an alternative way to control progress output suppression in
uv-cli, equivalent to using the `--no-progress` flag. This enhancement
simplifies configuration in CI environments and automated scripts by
eliminating the need to detect whether the script is running in a CI
environment.
Previously, disabling progress output required either passing the
`--no-progress` flag directly or implementing script logic to detect CI
environments and conditionally add the flag. With this change, users can
now simply set `UV_NO_PROGRESS=true` in their environment to achieve the
same effect.
The changes include:
- Adding the `UV_NO_PROGRESS` environment variable to the `EnvVars`
struct in `crates/uv-static/src/env_vars.rs`.
- Updating the `GlobalArgs` struct in `crates/uv-cli/src/lib.rs` to
include a new `no_progress` field that is bound to the `UV_NO_PROGRESS`
environment variable.
- Adding documentation for the new `UV_NO_PROGRESS` environment variable
in `docs/configuration/environment.md`.
## Test Plan
After creating a uv project using `uv init` in a temp directory in this
project:
```
cargo run cache clean && cargo run venv && UV_NO_PROGRESS=false cargo run sync
cargo run cache clean && cargo run venv && cargo run sync
```
produce the expected default behavior
```
cargo run cache clean && cargo run venv && UV_NO_PROGRESS=false cargo run sync
```
produces the same behavior as having the `--no-progress` flag.
## Summary
Look for a system level uv.toml config file under `/etc/uv/uv.toml` or
`C:\ProgramData`.
This PR is to address #6742 and start a conversation.
## Test Plan
This was tested locally manually on MacOS. I am happy to contribute
tests once we settle on the approach.

## Summary
This PR lifts the restriction that a package must come from a single
index. For example, you can now do:
```toml
[project]
name = "project"
version = "0.1.0"
readme = "README.md"
requires-python = ">=3.12"
dependencies = ["jinja2"]
[tool.uv.sources]
jinja2 = [
{ index = "torch-cu118", marker = "sys_platform == 'darwin'"},
{ index = "torch-cu124", marker = "sys_platform != 'darwin'"},
]
[[tool.uv.index]]
name = "torch-cu118"
url = "https://download.pytorch.org/whl/cu118"
[[tool.uv.index]]
name = "torch-cu124"
url = "https://download.pytorch.org/whl/cu124"
```
The construction is very similar to the way we handle URLs today: you
can have multiple URLs for a given package, but they must appear in
disjoint forks. So most of the code is just adding that abstraction to
the resolver, following our handling of URLs.
Closes#7761.
## Summary
This PR enables users to provide index credentials via named environment
variables.
For example, given an index named `internal` that requires a username
(`public`) and password
(`koala`), you can define the index (without credentials) in your
`pyproject.toml`:
```toml
[[tool.uv.index]]
name = "internal"
url = "https://pypi-proxy.corp.dev/simple"
```
Then set the `UV_INDEX_INTERNAL_USERNAME` and
`UV_INDEX_INTERNAL_PASSWORD`
environment variables, where `INTERNAL` is the uppercase version of the
index name:
```sh
export UV_INDEX_INTERNAL_USERNAME=public
export UV_INDEX_INTERNAL_PASSWORD=koala
```
## 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
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 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.
This PR adds a line to `docs/configuration/environment.md` that
documents `VIRTUAL_ENV_DISABLE_PROMPT`. If set to `1` when the virtual
environment is activated, then the virtual environment name will not be
prepended to a terminal prompt.
So far I've tested this in bash, but from the various activation
scripts, it looks like it is respected for a variety of shells.
Maintainers should please feel free to edit this PR directly. Thank you!
## Summary
Add a note in the documentation to clarify that `uv.toml` files take
precedence over `[tool.uv]` section in `pyproject.toml`, based on the
warning shown in the CLI:
```console
$ uv version
warning: Found both a `uv.toml` file and a `[tool.uv]` section in an adjacent `pyproject.toml`. The `[tool.uv]` section will be ignored in favor of the `uv.toml` file.
uv 0.4.2 (Homebrew 2024-09-01)
