v1.0.24

What's Changed

CSnakes now has the ability to install packages using uv instead of pip, which is significantly faster and improves app startup times.

Installing dependencies with uv

uv is an alternative to pip that can also install requirements from a file like requirements.txt or pyproject.toml. UV has a major benefit in a 10-100x speedup over pip, so your CSnakes applications will be faster to start.

To use uv to install packages:

...
services
    .WithPython()
    .WithVirtualEnvironment(Path.Join(home, ".venv"))
    .WithUvInstaller("requirements.txt"); // Optional - give the name of the requirements file, or pyproject.toml

Some other important notes about this implementation.

• Only uses uv to install packages and does not use uv to create projects or virtual environments.
• Must be used with WithVirtualEnvironment(), as pip requires a virtual environment to install packages into.
• Will use the UV_CACHE_DIR environment variable to cache the packages in a directory if set.
• Will disable the cache if the UV_NO_CACHE environment variable is set.

Features

• Add a UV package installer by @tonybaloney in #327

Bug Fixes

• Fix RedistributableLocator install when special folder is missing by @atifaziz in #329

Other Updates

• Reduce logging noise and move pip/env output to debug logs by @tonybaloney in #325
• Reuse computed installation lock file path by @atifaziz in #328

v1.0.23

What's Changed

This release has a new method for making it easier to distribute .NET packages which use a Python component by fetching Python for you, removing the need to install Python (or specify where it is).

You can replace all FromXXX() locators with a single FromRedistributable() and it will download Python 3.12, put it into %APP_DATA%/CSnakes and use that for all of the integration.

In future, we will allow overriding the major Python version (to say, 3.13)

• Add a new Locator that downloads and installs Python for you by @tonybaloney in #323
• Allow support for Conda environments being a different version of Python than Conda by @tonybaloney in #321
• Generate doc summaries with references to Python function by @atifaziz in #293

Bug Fixes

• Improved handling of name generation with single-character segments by @jozefhornik in #320

• Enable F5 debugging of source generator in Visual Studio by @atifaziz in #281
• Make generated code pretty to read (and write) by @atifaziz in #280

• Set variance of IGeneratorIterator<,,> type parameters by @atifaziz in #286
• Get error cause once by @atifaziz in #287
• Complete generator support for return value by @atifaziz in #288
• Use System.Threading.Lock on .NET 9. by @AaronRobinsonMSFT in #289
