Changelog

0.12.1

  • Update how configuration types are displayed in errors (#60)

  • Pin Python 3.12 for the examples (#62)

  • Minor fixes to fallback kernel mode (#62)

  • Clarify error message when project section is missing from pyproject.toml (#62)

0.12.0

  • Show more specific error if we fail to run sanity check (#55)

  • Add project config sanity-check (#55)

  • Accept both underscore and hyphen in project configuration (#55)

  • Sharpen the public/private API distinction even if this is not a library; only the main function and the kernel provisioner are public API now. (#57)

0.11.3

  • Set PYPROJECT_LOCAL_KERNEL_SANITY_CHECK in the environment when running the sanity check. (#51)

  • Log working directory setting when starting kernel process. (#51)

  • If pyproject.toml has no project section, do not identify it as belonging to a project manager that requires the project section. (#52)

0.11.2

  • Enable the binary path in the virtual environment for use-venv and hatch configurations (#48)

  • Launch fallback kernel using python -m. (#49)

  • Test using Python 3.13. (#45)

0.11.1

  • Add another kernelspec Pyproject Local (use-venv) which defaults to the use-venv setting, using the virtual environment directly. (#43 and cb90a20).

  • PyprojectKernelProvisioner is now configurable like other “jupyter objects” using the same config system. However, pyproject.toml configuration should be preferred. (#43)

  • When preparing to start the kernel, only errors from known checks are caught and passed off to the starting fallback kernel. (aaed1da)

0.11.0

  • Use local kernel provisioning to launch the kernel. This is a more standard way to do it, with less overhead and less compatibility issues. (#39)
  • Improved fallback mode on errors and documentation around this
  • License update again, more or less reverting what was done in v0.10.0, because the relevant code has been removed. (#39)
  • The package now installs an executable pyproject_local_kernel that is used interally (#39)
  • This one goes to eleven, it really does

0.10.1

  • If there is no pyproject.toml at all, show an error message to the user instead of throwing an exception. Fixes a regression. (#34)
  • Fix running tests in sdist (#33)

0.10.0

  • Support interrupting the kernel on windows (#30, #32)
  • Now uses jupyter-client to launch the kernel process (#30)
  • License was updated after we copied one file from ipykernel, now a combination of MIT and BSD 3-clause.

0.9.1

  • Call hatch env find using --no-color for robustness (#27)
  • Support a command string for python-cmd configuration (#28)
  • Better test setup for jupyter using pytest (#27)

0.9.0

  • Check configuration value types strictly and warn on unknown configuration
  • Examples in the repository now use Uv

0.8.1

  • Fix problem trying to forward SIGCHLD to kernel, which was maybe specific to Python 3.8 (and not-windows) (#24)

0.8.0

  • Change how hatch projects are run: detect the (default) virtual env path and run python from there. User has to ensure virtualenv dependencies are synchronized. (#23)

0.7.2

  • Published documentation to a new website using mkdocs
  • Copyedited documentation

0.7.1

  • Use Uv as first fallback if no explicit project manager can be identified from the pyproject if uv is in the command path. Use Rye as the second fallback in the same way.

0.7.0

  • Use uv run for uv projects. Requires uv 0.2.29 or later. Uses uv run --with ipykernel which means it will run as before if ipykernel is already installed, or run in an overlay environment (ipykernel + base pyproject) if not.
  • Include kernel start failure messages in user visible text in more cases such as “command not found”.

0.6.0

  • Support configuration use-venv for setting a name of a virtualenv to use
  • Support Uv (in a basic way, by assuming use-venv=".venv" for uv)

0.5.5

  • Fix ProjectDetection.path which should hold the path to the pyproject file
  • Added trusted publishing (for PyPI) workflow on github

0.5.4

  • Enable debugging for the Pyproject Local kernel (just like the regular ipykernel)
  • More extensive tests, on linux and windows, including notebook execution

0.5.3

  • Add tests. Moved main logic to module to facilitate.
  • Update readme

0.5.2

  • Use tomllib for newer Python, and tomli as fallback
  • Catch all exceptions when starting the kernel, so that the fallback can be started in most situations.
  • More detailed error messages in the fallback

0.5.1

  • Cleaned up unnecessary log output
  • Set repo URL in package

0.5.0

  • Changed name to pyproject-local-kernel (previously ryeish-kernel)
  • Now supports Rye, PDM, Poetry, Hatch and custom configuration
