Hatch Versions Save

Changed:

• The run/env run, fmt and shell commands now only change the current working directory to the project root if not already inside the project
• The shell command now accepts a single argument to specify the environment to enter which overrides the standard choice mechanisms. The arguments determining shell options have been converted to flags.

Added:

• Add test command
• The run command can now execute scripts that define inline metadata for dependencies and Python version constraints
• The virtual environment type now supports the ability to use UV in place of pip & virtualenv
• Add self report command for submitting pre-populated bug reports to GitHub
• The reserved environment used for static analysis is now completely configurable
• Add the following methods to the environment interface for complete control over output during life cycle management: app_status_creation, app_status_pre_installation, app_status_post_installation, app_status_project_installation, app_status_dependency_state_check, app_status_dependency_installation_check, app_status_dependency_synchronization
• Add binaries for 32-bit versions of Windows
• Read configuration from any ~/.pypirc file for the index publisher
• Use the Git user as the default username for new project URL metadata
• Add HATCH_DEBUG environment variable that when enabled will show local variables in the case of unhandled tracebacks
• The env show command now outputs data about all internal environments when using the --json flag
• Upgrade default CPython distributions to 20240415
• Upgrade default PyPy distributions to 7.3.15
• Upgrade Ruff to 0.4.2
• Upgrade PyApp to 0.19.0 for binary builds
• Bump the minimum supported version of Hatchling to 1.24.2
• Bump the minimum supported version of virtualenv to 20.26.1

Fixed:

• Maintain consistent data paths for case insensitive file systems
• When projects derive dependencies from metadata hooks, there is now by default a status indicator for when the hooks are executed for better responsiveness
• Properly support projects with a pyproject.toml file but no project table e.g. applications
• Fix the fmt command when automatically installing plugin dependencies
• Fix dependency inheritance for the template of the types environment for new projects
• Fix warnings related to tar file extraction on Python 3.12+ when unpacking Python distributions for installation
• De-select Ruff rule E501 for the fmt command by default since it conflicts with the formatter
• Fix colored output from build targets on the first run (build environment creation status indicator issue)
• Set the packaging dependency version as >=23.2 to avoid its URL validation which can conflict with context formatting
• Fix the exit code when there happens to be an unhandled exception
• No longer capture both stdout and stderr streams when parsing metadata payloads from build environments
• Fix the README.md file template for new projects to avoid Markdown linting issues

Fixed:

• Limit the maximum version of virtualenv due to a backward incompatible change
• Upgrade PyApp to 0.12.0 for binary builds

Fixed:

• Add .venv to the list of directories that cannot be traversed
• Output from the core Application utility now writes to stderr

Fixed:

• Maintain file permissions for shared-scripts option/shared_scripts build data of the wheel target

Added:

• Add shared_data and shared_scripts build data for the wheel target

Added:

• Add shared-scripts option for the wheel target

Fixed:

• Support recursive optional dependencies
• Set the packaging dependency version as >=23.2 to avoid its URL validation which can conflict with context formatting

Fixed:

• Fix reading metadata from source distributions when fields are dynamic but not part of core metadata like entry points

Fixed:

• Only read source distribution metadata for fields that are explicitly defined as dynamic

Fixed:

• Fix the custom build hook when using dynamic dependencies

Fixed:

• Fix regression when loading metadata from source distributions
• Fix metadata hooks when building wheels from source distributions
