## Summary
This PR adds `--package` support to `uv build`, such that you can use
`--package` from anywhere in a workspace to build any member.
If a source directory is provided, we use that as the workspace root.
If a file is provided, we error.
For now, `uv build` only builds the current package, making it
semantically identical to `uv sync`.
## Summary
This PR allows users to run `uv build --wheel ./path/to/source.tar.gz`
to build a wheel from a source distribution. This is also the default
behavior if you run `uv build ./path/to/source.tar.gz`. If you pass
`--sdist`, we error.
## Summary
This PR exposes uv's PEP 517 implementation via a `uv build` frontend,
such that you can use `uv build` to build source and binary
distributions (i.e., wheels and sdists) from a given directory.
There are some TODOs that I'll tackle in separate PRs:
- [x] Support building a wheel from a source distribution (rather than
from source) (#6898)
- [x] Stream the build output (#6912)
Closes https://github.com/astral-sh/uv/issues/1510
Closes https://github.com/astral-sh/uv/issues/1663.
## Summary
I'm not convinced that the behavior is correct as-implemented. When the
user passes a `--python >=3.8` or we discover a `requires-python` from
the workspace, we're currently writing that request out to
`.python-version`. I would probably rather that we write the resolved
patch version?
Closes https://github.com/astral-sh/uv/issues/6821.
- Respect `UV_PROJECT_ENVIRONMENT` when in project root
- Add `--no-project` and `--no-workspace` to opt-out of above and
`requires-python` detection
- Rename `[NAME]` to `[PATH]` in CLI
Previously, we were always asking Cargo to rebuild `uv-cli` if
`.git/HEAD` had changed. But in a worktree, `.git` is a file, not a
directory. And the file contains the path to git's internal worktree
state, which also has its own `HEAD` file. So in the case of a worktree,
we read the file and tell Cargo to watch the worktree-specific `HEAD`
file instead of `.git/head`.
The main thing this fixes is that, previously, in a worktree, `cargo
build` would *always* re-compile `uv` even if nothing changed.
This doesn't impact or fix anything in "typical" clones of uv though.
Only in worktrees.
Closes#6196, Closes#6197
## Summary
The interface here is intentionally a bit more limited than `uv pip
compile`, because we don't want `requirements.txt` to be a system of
record -- it's just an export format. So, we don't write annotation
comments (i.e., which dependency is requested from which), we don't
allow writing extras, etc. It's just a flat list of requirements, with
their markers and hashes.
Closes#6007.
Closes#6668.
Closes#6670.
Changes the `uv init` experience with a focus on working for more
use-cases out of the box.
- Adds `--app` and `--lib` options to control the created project style
- Changes the default from a library with `src/` and a build backend
(`--lib`) to an application that is not packaged (`--app`)
- Hides the `--virtual` option and replaces it with `--package` and
`--no-package`
- `--no-package` is not allowed with `--lib` right now, but it could be
in the future once we understand a use-case
- Creates a runnable project
- Applications have a `hello.py` file which you can run with `uv run
hello.py`
- Packaged applications, e.g., `uv init --app --package` create a
package and script entrypoint, which you can run with `uv run hello`
- Libraries provide a demo API function, e.g., `uv run python -c "import
name; print(name.hello())"` — this is unchanged
Closes#6471
## Summary
The basic idea here is: any project can either be a package, or not
("virtual").
If a project is virtual, we don't build or install it.
A project is virtual if either of the following are true:
- `tool.uv.virtual = true` is set.
- `[build-system]` is absent.
The concept of "virtual projects" only applies to workspace member right
now; it doesn't apply to `path` dependencies which are treated like
arbitrary Python source trees.
TODOs that should be resolved prior to merging:
- [ ] Documentation
- [ ] How do we reconcile this with "virtual workspace roots" which are
a little different -- they omit `[project]` entirely and don't even have
a name?
- [x] `uv init --virtual` should create a virtual project rather than a
virtual workspace.
- [x] Running `uv sync` in a virtual project after `uv init --virtual`
shows `Audited 0 packages in 0.01ms`, which is awkward. (See:
https://github.com/astral-sh/uv/pull/6588.)
Closes https://github.com/astral-sh/uv/issues/6511.
## Summary
This PR revives https://github.com/astral-sh/uv/pull/4944, which I think
was a good start towards adding `--trusted-host`. Last night, I tried to
add `--trusted-host` with a custom verifier, but we had to vendor a lot
of `reqwest` code and I eventually hit some private APIs. I'm not
confident that I can implement it correctly with that mechanism, and
since this is security, correctness is the priority.
So, instead, we now use two clients and multiplex between them.
Closes https://github.com/astral-sh/uv/issues/1339.

transitive-yanked-and-unyanked-dependency-a-0abad3b6 --index-url
https://127.0.0.1:8443/simple-html` failed with:

failed with the expected error (invalid resolution) and made valid
requests.
Verified that `cargo run pip install

'https://127.0.0.1:8443/simple-html' --trusted-host '127.0.0.2' -n` also
failed.
Previously, we excluded these and only looked at system interpreters.
However, it makes sense for this to match the typical Python discovery
experience. We could consider swapping the default... I'm not sure what
makes more sense. If we change the default (as written now) — this could
arguably be a breaking change.
This is a fallback mode that we supported when we decided to use PEP 517
builds by default. I can't find a single reference to it on GitHub or in
our issue tracker, so I want to drop support for it as part of v0.3.0.
- Removes "experimental" labels from command documentation
- Removes preview warnings
- Removes `PreviewMode` from most structs and methods — we could keep it
around but I figure we can propagate it again easily where needed in the
future
- Enables preview behavior by default everywhere, e.g., `uv venv` will
download Python versions
This PR migrates uv's use of `chrono` to `jiff`.
I did most of this work a while back as one of my tests to ensure Jiff
could actually be used in a real world project. I decided to revive
this because I noticed that `reqwest-retry` dropped its Chrono
dependency,
which is I believe the only other thing requiring Chrono in uv.
(Although, we use a fork of `reqwest-middleware` at present, and that
hasn't been updated to latest upstream yet. I wasn't quite sure of the
process we have for that.)
In course of doing this, I actually made two changes to uv:
First is that the lock file now writes an RFC 3339 timestamp for
`exclude-newer`. Previously, we were using Chrono's `Display`
implementation for this which is a non-standard but "human readable"
format. I think the right thing to do here is an RFC 3339 timestamp.
Second is that, in addition to an RFC 3339 timestamp, `--exclude-newer`
used to accept a "UTC date." But this PR changes it to a "local date."
That is, a date in the user's system configured time zone. I think
this makes more sense than a UTC date, but one alternative is to drop
support for a date and just rely on an RFC 3339 timestamp. The main
motivation here is that automatically assuming UTC is often somewhat
confusing, since just writing an unqualified date like `2024-08-19` is
often assumed to be interpreted relative to the writer's "local" time.

- First commit avoids overwriting dependencies with different markers.
- Second commit supports adding from requirements files.
## Test Plan
`cargo test`
## Summary
We now persist the `ResolverInstallerOptions` when writing out a tool
receipt. When upgrading, we grab the saved options, and merge with the
command-line arguments and user-level filesystem settings (CLI > receipt
> filesystem).
The loose consensus is that "fetch" doesn't have much meaning and that a
boolean flag makes more sense from the command line.
1. Adds `--allow-python-downloads` (hidden, default) and
`--no-python-downloads` to the CLI to quickly enable or disable
downloads
2. Deprecates `--python-fetch` in favor of the options from (1)
3. Removes `python-fetch` in favor of a `python-downloads` setting
5. Adds a `never` variant to the enum, allowing even explicit installs
to be disabled via the configuration file
## Test plan
I tested this with various `pyproject.toml`-level settings and `uv venv
--preview --python 3.12.2` and `uv python install 3.12.2` with and
without the new CLI flags.
## Summary
I think this seems reasonable... Otherwise, we might not go back to PyPI
to revalidate the list of available versions despite the user passing
`--upgrade`.
## Summary
Resolves#5188. Most of the changes involve creating a new function in
`tool/common.rs` to contain the common functionality previously found in
`tool/install.rs`.

## Summary
`uv tree` will now filter to the current platform by default. You can
pass `--universal` to show the entire tree.
Closes https://github.com/astral-sh/uv/issues/5760.
## Summary
Partially resolves#5561. Haven't added overrides support yet but I can
add it tomorrow if the current approach for constraints is ok.
## Test Plan
`cargo test`
Manually checked trace logs after changing the constraints.
Part of #4454
e.g. for `uv help pip compile`
```
Python options:
--python <PYTHON>
The Python interpreter against which to compile the requirements.
By default, uv uses the virtual environment in the current working directory or any parent
directory, falling back to searching for a Python executable in `PATH`. The `--python`
option allows you to specify a different interpreter.
Supported formats:
- `3.10` looks for an installed Python 3.10 using `py --list-paths` on Windows, or
`python3.10` on Linux and macOS.
- `python3.10` or `python.exe` looks for a binary with the given name in `PATH`.
- `/home/ferris/.local/bin/python3.10` uses the exact Python at the given path.
-p, --python-version <PYTHON_VERSION>
The minimum Python version that should be supported by the resolved requirements (e.g., `3.8` or `3.8.17`).
If a patch version is omitted, the minimum patch version is assumed. For example, `3.8` is mapped to `3.8.0`.
--python-preference <PYTHON_PREFERENCE>
Whether to prefer using Python installations that are already present on the system, or those that are downloaded and installed by uv
Possible values:
- only-managed: Only use managed Python installations; never use system Python installations
- managed: Prefer managed Python installations over system Python installations
- system: Prefer system Python installations over managed Python installations
- only-system: Only use system Python installations; never use managed Python installations
--python-fetch <PYTHON_FETCH>
Whether to automatically download Python when required
Possible values:
- automatic: Automatically fetch managed Python installations when needed
- manual: Do not automatically fetch managed Python installations; require explicit installation
```
## Summary
This PR deprecates the `--isolated` flag. The treatment varies across
the APIs:
- For non-preview APIs, we warn but treat it as equivalent to
`--no-config`.
- For preview APIs, we warn and ignore it, with two exceptions...
- For `tool run` and `run` specifically, we don't even warn, because we
can't differentiate the command-specific `--isolated` from the global
`--isolated`.
## Summary
The culmination of #4730. We now have `uv run --isolated` which always
uses a fresh environment (but includes the workspace dependencies as
needed). This enables you to test with strict isolation (e.g., `uv run
--isolated -p foo` will ensure that `foo` is unable to import anything
that isn't an actual dependency).
Closes#5430.
## Summary
This PR gets rid of the global `--isolated` flag (which serves a bunch
of independent responsibilities right now) on `uv tool run` in favor of
a dedicated `--isolated` flag, which tells uv to avoid re-using an
existing tool environment for this invocation. We'll add the same thing
to `uv run`, to avoid using the base project environment.
This will become a bit clearer in #5466, when we deprecate the
`--isolated` flag on the preview APIs.
## Summary
The idea here is that we hide all resolver output (the grayed out
resolver messages, plus the list of environment modifications) by
default in `uv run` and `uv tool run`. You can pass `--show-resolution`
to re-enable them.
Closes https://github.com/astral-sh/uv/issues/5458.
## Summary
Right now, `--isolated` is read from `uv run` and `uv init` to avoid
discovering the current workspace (or project). This PR moves that
behavior to a dedicated `--no-workspace` flag for `uv init`, and
`--no-project` for `uv run`. They could use the same flag, but
`--no-project` feels confusing for `uv init`, and `--no-workspace` seems
confusing for `uv run` (especially so once you read the documentation,
where we refer to the thing you're omitting as the project).
Closes https://github.com/astral-sh/uv/issues/5429.
## Summary
uv run --directory <path> means that one doesn't have to change to a
project's directory to run programs from it. It makes it possible to use
projects as if they are tool installations.
To support this, first the code reading .python-version was updated so
that
it can read such markers outside the current directory. Note the minor
change this causes (if I'm right), described in the commit.
## Test Plan
One test has been added.
## --directory
Not sure what the name of the argument should be, but it's following uv
sync's directory for now.
Other alternatives could be "--project". Uv run and uv tool run should
probably find common agreement on this (relevant for project-locked
tools).
I've implemented this same change in Rye, some time ago, and then we
went
with --pyproject `<`path to pyproject.toml file`>`. I think using
pyproject.toml file path and not directory was probably a mistake, an
overgeneralization one doesn't need.
## Summary
Adds a `--relocatable` CLI arg to `uv venv`. This flag does two things:
* ensures that the associated activation scripts do not rely on a
hardcoded
absolute path to the virtual environment (to the extent possible; `.csh`
and
`.nu` left as-is)
* persists a `relocatable` flag in `pyvenv.cfg`.
The flag in `pyvenv.cfg` in turn instructs the wheel `Installer` to
create script
entrypoints in a relocatable way (use `exec` trick + `dirname $0` on
POSIX;
use relative path to `python[w].exe` on Windows).
Fixes: #3863
## Test Plan
* Relocatable console scripts covered as additional scenarios in
existing test cases.
* Integration testing of boilerplate generation in `venv`.
* Manual testing of `uv venv` with and without `--relocatable`
## Summary
This PR adds support for `uv lock` and `uv sync` in the standardized
benchmarks script.
Part of: https://github.com/astral-sh/uv/issues/5263.
## Test Plan
For example:
```sh
python scripts/bench/__main__.py --uv-project --benchmark resolve-cold ./scripts/requirements/trio.in --verbose
```
## Summary
I think it makes no sense to allow `--editable` and `--exclude-editable`
at the same time.
## Test Plan
```console
$ cargo run -- pip list --editable --exclude-editable
error: the argument '--editable' cannot be used with '--exclude-editable'
Usage: uv.exe pip list --editable
For more information, try '--help'.
```
## Summary
It's hard for me to imagine a scenario in which a user passed
`--reinstall`, but wanted us to keep respecting cached data for a
package. For example, to actually "rebuild and reinstall" an editable
today, you have to pass both `--reinstall` and `--refresh`.
This PR makes `--reinstall` imply `--refresh`, so we always validate
that the cached data is fresh.
Closes https://github.com/astral-sh/uv/issues/5424.
## Summary
Users can now run `uv cache prune --ci` (open to feedback on the name of
that flag) to remove all pre-built wheels from the cache, leaving behind
zipped, built wheels (which tend to be the most expensive assets to
re-create). This should greatly increase cache performance in CI
environments, since uploading unzipped wheels can actually hurt
performance if you're persisting the uv cache.
Closes https://github.com/astral-sh/uv/issues/5282.
## Summary
Prefers, in order:
- The major-minor version of an interpreter discovered via `--python`.
- The `requires-python` from the workspace.
- The major-minor version of the default interpreter.
If the `--python` request is a version or a version range, we use that
without fetching an interpreter.
Closes https://github.com/astral-sh/uv/issues/5299.
## Summary
resolves https://github.com/astral-sh/uv/issues/5217
## Test Plan
existing tests pass (should be perfectly backwards compatible) + added a
few tests to cover the new functionality. in particular, in addition to
the simple use of `--show-version-specifiers`, its interaction with
`--invert` and `--package` flags are tested.
## Summary
Implements the `uv init` command, which initializes a project
(`pyproject.toml`, `README.md`, `src/__init__.py`) in the current
directory, or in the given path. `uv init` also does workspace
discovery.
Resolves https://github.com/astral-sh/uv/issues/1360.

## Summary
You can now use `uv run --locked` to assert that the lockfile doesn't
change, or `uv run --frozen` to run without attempting to update the
lockfile at all.
Closes https://github.com/astral-sh/uv/issues/5185.
## Summary
This is an alternative to `--require-hashes` which will validate a hash
if it's present, but ignore requirements that omit hashes or are absent
from the lockfile entirely.
So, e.g., transitive dependencies that are missing will _not_ error; nor
will dependencies that are included but lack a hash.
Closes https://github.com/astral-sh/uv/issues/3305.
## Summary
Fixes#5082.
Adds a new `Printer::NoProgress` that is identical to `Printer::Default`
but doesn't draw any progress bar.
## Test Plan
It seems to me that as of now it's not possible to use `insta-cmd` to
get any progress bar in the comparable output of command.
Best way to test this would be to run any command that usually shows
progress indicators like `uv pip install` with and without
`--no-progress` options.
## Summary
First part of https://github.com/astral-sh/uv/issues/5093.
Remaining:
- Global settings
- `pip`-specific settings (some will be copied-over from here)
- Auto-generating the "Possible values" for enums
## Summary
I'll open follow-up tickets for Windows support.
Closes https://github.com/astral-sh/uv/issues/4953.

## Summary
Fixes#4941.
This PR adds a `--no-pager` option in `help` command to explicitly
disable the pager.
I noted that the template used for the text printed when calling `help`
with no argument or option doesn't show any option. It made sense before
this PR since `help` didn't have any available option. Though I'm unsure
if it makes sense to update the template as it would make it extremely
verbose as all the global options would be shown too.
I leave the decision to you.
## Test Plan
I ran `cargo run -- help` to verify `--isolated` was visible and it.
I ran clippy with `cargo clippy --workspace --all-targets --all-features
--locked -- -D warnings` as CI does.
I also ran tests locally with:
```
cargo nextest run \
--features python-patch \
--workspace \
--status-level skip --failure-output immediate-final --no-fail-fast -j 12 --final-status-level slow
```
## Summary
This PR makes the `--isolated` global argument visible, previously it
was hidden.
Fixes#4981.

Adds a `uv python pin` command to write to a `.python-version` file.
We support all of our Python version request formats. We also support a
`--resolved` flag to pin to a specific interpreter instead of the
provided version. We canonicalize the request with #4949, it's not just
printed verbatim. We always attempt to find the interpreter so we can
warn if it's not available. With `--resolved`, if we can't find the
interpreter we fail. If no arguments are provided, we'll attempt to
display the current pin.
In the future:
- We should confirm that this satisfies the `Requires-Python` metadata
if a `pyproject.toml` is present
- We should support writing to a `uv.python-version` field if
`pyproject.toml` or `uv.toml` are present
- We should support finding and updating the "nearest" Python version
file (looking in ancestors)
- We should support finding version files in workspaces
- We should support some sort of global pin
## Summary
Allows `--all` as an alternative to specifying specific targets.

I feel like I'm always drowning in the help output from `uv` because we
have so many options.
I basically agree with the commentary in
https://github.com/clap-rs/clap/issues/4687 that having different
behaviors for `-h` and `--help` is surprising. I think `--help` is more
obvious for users and I want to optimize for that experience.
This roughly matches the help menus in Cargo and pip.
The `uv help` command can be used for long help. In #4906 and #4909 we
improve that command.
Extends #4904 which adds test cases for the existing behavior.
The changes in https://github.com/astral-sh/uv/pull/4708 caused an
overflow in debug mode only of the 1MB default stack size in windows
during clap. This means that even trivial wrong argument tests would
fail without increasing the stack size. As remedy, we box the clap
types.
Previously this displayed:
```
❯ cargo run -q -- --help
The command line interface for the uv binary.
Usage: uv [OPTIONS] <COMMAND>
```
This is.. weird. Here I remove it entirely. I could see adding
`about_long` text being helpful in the future.
Whew this is a lot.
The user-facing changes are:
- `uv toolchain` to `uv python` e.g. `uv python find`, `uv python
install`, ...
- `UV_TOOLCHAIN_DIR` to` UV_PYTHON_INSTALL_DIR`
- `<UV_STATE_DIR>/toolchains` to `<UV_STATE_DIR>/python` (with
[automatic
migration](https://github.com/astral-sh/uv/pull/4735/files#r1663029330))
- User-facing messages no longer refer to toolchains, instead using
"Python", "Python versions" or "Python installations"
The internal changes are:
- `uv-toolchain` crate to `uv-python`
- `Toolchain` no longer referenced in type names
- Dropped unused `SystemPython` type (previously replaced)
- Clarified the type names for "managed Python installations"
- (more little things)
Adds a `toolchain-fetch` option alongside `toolchain-preference` with
`automatic` (default) and `manual` values allowing automatic toolchain
fetches to be disabled (replaces
https://github.com/astral-sh/uv/pull/4425). When `manual`, toolchains
must be installed with `uv toolchain install`.
Note this was previously implemented with `if-necessary`, `always`,
`never` variants but the interaction between this and
`toolchain-preference` was too confusing. By reducing to a binary
option, things should be clearer. The `if-necessary` behavior moved to
`toolchain-preference=installed`. See
https://github.com/astral-sh/uv/pull/4601#discussion_r1657839633 and
https://github.com/astral-sh/uv/pull/4601#discussion_r1658658755

Moves `--from` to a hidden argument — we allow it still but we validate
that it is compatible with whatever is passed to `uv tool install
<package>`. The positional package can now be a full specification,
allowing things like `uv tool install black==24.2.0`.
## Summary
- Adds a `--extra` flag to `uv add` that allows activating extras
without the PEP508 syntax.
- `uv add` now errors if the update is ambiguous (e.g. the dependency is
present twice with different markers)
- `uv add` is smarter about updates. For example, `uv add flask==3.0.0`
followed by `uv add flask --extra dotenv` preserves the previous version
specifier.
Resolves https://github.com/astral-sh/uv/issues/4419.
Adds detection of existing entry points, avoiding clobbering entry
points that were installed by another tool. If we see any existing entry
point collisions, we'll stop instead of overwriting them. The `--force`
flag can be used to opt-in to overwriting the files; we can't use `-f`
because it's taken by `--find-links` which is silly. The `--force` flag
also implies replacing a tool previously installed by uv (the
environment is rebuilt).
Similarly, #4504 adds support for reinstalls that _will not_ clobber
entry points managed by other tools.
## Summary
If the package _isn't_ marked as `workspace = true`, locking will fail
given:
```rust
let workspace_package_declared =
// We require that when you use a package that's part of the workspace, ...
!workspace.packages().contains_key(&requirement.name)
// ... it must be declared as a workspace dependency (`workspace = true`), ...
|| matches!(
source,
Some(Source::Workspace {
// By using toml, we technically support `workspace = false`.
workspace: true,
..
})
)
// ... except for recursive self-inclusion (extras that activate other extras), e.g.
// `framework[machine_learning]` depends on `framework[cuda]`.
|| &requirement.name == project_name;
if !workspace_package_declared {
return Err(LoweringError::UndeclaredWorkspacePackage);
}
```
Closes https://github.com/astral-sh/uv/issues/4552.
This is the minimal "working" implementation. In summary, we:
- Resolve the requested requirements
- Create an environment at `$UV_STATE_DIR/tools/$name`
- Inspect the `dist-info` for the main requirement to determine its
entry points scripts
- Link the entry points from a user-executable directory
(`$XDG_BIN_HOME`) to the environment bin
- Create an entry at `$UV_STATE_DIR/tools/tools.toml` tracking the
user's request
The idea with `tools.toml` is that it allows us to perform upgrades and
syncs, retaining the original user request (similar to declarations in a
`pyproject.toml`). I imagine using a similar schema in the
`pyproject.toml` in the future if/when we add project-levle tools. I'm
also considering exposing `tools.toml` in the standard uv configuration
directory instead of the state directory, but it seems nice to tuck it
away for now while we iterate on it. Installing a tool won't perform a
sync of other tool environments, we'll probably have an explicit `uv
tool sync` command for that?
I've split out todos into follow-up pull requests:
- #4509 (failing on Windows)
- #4501
- #4504Closes#4485
## Summary
This is an intermediary change in enabling universal resolution for
`requirements.txt` files. To start, we need to be able to preserve
markers in the `requirements.txt` output _and_ propagate those markers,
such that if you have a dependency that's only included with a given
marker, the transitive dependencies respect that marker too.
Closes#1429.

## Summary
Resolves https://github.com/astral-sh/uv/issues/4439 partially.
Implements for `uv pip tree`:
- `--no-dedupe` flag, similar to `cargo tree --no-dedupe` .
- denote dependency cycles with `(#)` and add a footnote if there's a
cycle (using `(*)` would require keeping track of the cycle state, so
opted to do this instead).
<!-- What's the purpose of the change? What does it do, and why? -->
## Test Plan
The existing tests pass + added a couple of tests to validate
`--no-dedupe` behavior.
<!-- How was it tested? -->
## Summary
This PR moves all the CLI code into its own crate, separate from the
`uv` crate. The `uv` crate is iterated on frequently, and the CLI code
comprises a significant portion of it but rarely changes. Removing the
CLI code reduces the `uv` crate size from 1.4MiB to 1.0MiB.
