Add supporting new package manager uv for Python

[staners2]

Tell us more.

Hi. The Python world has created new package manager, which is more productive than pip or poetry.
Package manager for python - uv

uv usage standard pep-621. There is a problem that Renovate only updates the version specified in pyproject.toml, but does not update it in requirements.txt (this is analog to lock files in other languages). This causes trouble, because of which you have to go into this MR and manually push a commit with compile requirements.txt (lock file).

You can add an update requirements.txt (lock file, it may be named differently) in the same commit?

Hi there,

You're asking us to support a new package manager. We need to know some basic information about this package manager first. Please copy/paste the new package manager questionnaire, and fill it out in full.

Once the questionnaire is filled out we'll decide if we want to support this new manager.

Good luck,

The Renovate team

I think this is possible with:
https://docs.renovatebot.com/modules/manager/pip-compile/#non-configured-filematch

[rarkins]

Right now pip-compile runs pip-tools. Unless uv is a drop-in replacement for pip-compile then it's probably better to have its own manager, especially if it has a simple relationship between pyproject.toml and requirements.txt instead of pip-compile's more complex approach.

New package manager questionnaire

Did you read our documentation on adding a package manager?

• I've read the adding a package manager documentation.

Basics

What's the name of the package manager?

uv

What language(s) does this package manager support?

Python

How popular is this package manager?

This is a new manager, but it feels like it will replace pip or poetry

Does this language have other (competing?) package managers?

poetry, pip

• Yes (give names).
• No.

What are the big selling points for this package manager?

• performance
• doesn't depend to python
• usage native standard pep-621

Explain how this package manager is different from existing ones

• It was written in a different programming language, which makes it independent of the environment of the Python programming language itself
• It is very performance
• Config file pyproject.toml usage native standard pep-621

Detecting package files

What kind of package files, and names, does this package manager use?

• pyproject.toml - File described dependencies, he usage to generate a lock file. Usage standard pep-621
• requirements.txt - The manager installs the dependencies described in this file (analog lock file). Created after uv pip compile -o requirements.txt

Which fileMatch pattern(s) should Renovate use?

(^|/)pyproject\\.toml$

Do many users need to extend the fileMatch pattern for custom file names?

• Yes, provide details.
• No.

Is the fileMatch pattern going to get many "false hits" for files that have nothing to do with package management?

No.

Parsing and Extraction

Can package files have "local" links to each other that need to be resolved?

No

Package file parsing method

The package files should be:

• Parsed together (in serial).
• Parsed independently.

Which format/syntax does the package file use?

• JSON
• TOML
• YAML
• Custom (explain below)

How should we parse the package files?

• Off the shelf parser.
• Using regex.
• Custom-parsed line by line.
• Other.

Does the package file have different "types" of dependencies?

Usage standard pep-621 and cli uf pip compile --extra {type}

• Yes, production and development dependencies.
• No, all dependencies are treated the same.

List all the sources/syntaxes of dependencies that can be extracted

Don't know

Describe which types of dependencies above are supported and which will be implemented in future

Don't know

Versioning

What versioning scheme does the package file(s) use?

classic semantic version - x.y.z

Does this versioning scheme support range constraints, like ^1.0.0 or 1.x?

• Supports range constraints (for example: ^1.0.0 or 1.x), provide details.
• No.

Lookup

Is a new datasource required?

• Yes, provide details.
• No.

Will users want (or need to) set a custom host or custom registry for Renovate's lookup?

• Yes, provide details.
• No.

Where can Renovate find the custom host/registry?

• No custom host or registry is needed.
• In the package file(s), provide details.
• In some other file inside the repository, provide details.
• User needs to configure Renovate where to find the information, provide details.

Are there any constraints in the package files that Renovate should use in the lookup procedure?

Don't know

• Yes, there are constraints on the parent language (for example: supports only Python v3.x), provide details.
• Yes, there are constraints on the parent platform (for example: only supports Linux, Windows, etc.), provide details.
• Yes, some other kind of constraint, provide details.
• No constraints.

Will users need the ability to configure language or other constraints using Renovate config?

• Yes, provide details.
• No.

Artifacts

Does the package manager use a lock file or checksum file?

requirements.txt - lock file

• Yes, uses lock file.
• Yes, uses checksum file.
• Yes, uses lock file and checksum file.
• No lock file or checksum.

Is the locksum or checksum mandatory?

Don't know

• Yes, locksum is mandatory.
• Yes, checksum is mandatory.
• Yes, lock file and checksum are mandatory.
• No mandatory locksum or checksum.
• Package manager does not use locksums or checksums.

If lockfiles or checksums are used: what tool and exact commands should Renovate use to update one (or more) package versions in a dependency file?

Comand not found

Package manager cache

Does the package manager use a cache?

https://github.com/astral-sh/uv?tab=readme-ov-file#dependency-caching

• Yes, provide details.
• No.

If the package manager uses a cache, how can Renovate control the cache?

uv cache clean - delete .cache directory

• Package manager does not use a cache.
• Controlled via command line interface, provide details.
• Controlled via environment variables, provide details.

Should Renovate keep a cache?

• Yes, ignore/disable the cache.
• No.

Generating a lockfile from scratch

Renovate can perform "lock file maintenance" by getting the package manager to generate a lockfile from scratch.
Can the package manager generate a lockfile from scratch?
uv pip compile -o requirements.txt
Must be usage override this command, because compile would like execute with parameters --extra tests --extra linters, this group dependencies (dev/prod).

• Yes, explain which command Renovate should use to generate the lockfile.
• No, the package manager does not generate a lockfile from scratch.
• No, the package manager does not use lockfiles.

What else should we know about this package manager?
