Release Notes

mwouts/jupytext (jupytext)

v1.18.1

Compare Source

Fixed

• Fixed test test_check_source_is_newer_when_using_jupytext_sync to work reliably on systems with low filesystem timestamp resolution (#​1460)

Changed

• We now use pixi to maintain the local Python environments used for developing and testing Jupytext.

v1.18.0

Compare Source

Added

• The documentation has a chapter on the Jupytext Sync extension for VS Code (#​1395)
• We have added a new option --check-source-is-newer to the Jupytext CLI. Use this option if you want to make sure that the file passed as argument to Jupytext is the newest of all paired files, and/or newer than the destination file.
• We have added a section on Jupyter Collaboration which also provides a very useful autoreload functionality (#​406, #​1401)
• Pairing groups allow you to define different pairing configurations for specific subsets of notebooks. The formats configuration option now supports a list of format dictionaries for first-match pairing. Use [[formats]] sections in your TOML configuration to define multiple format specifications, where the first matching format is used. This allows applying different pairing rules to notebooks in different locations, such as generating documentation markdown files only for tutorial notebooks (#​1383)
• We have added more tests to document the complex pairing formats, which also work on Windows (#​1028)
• Pairing into nested folders was fixed on Windows (#​1028)
• Jupytext is now tested with Python 3.14 (#​1456)

Fixed

• The Jupytext CLI now detects if a file it has read or consulted has been modified while it was processing it. That can happen in the context of the Jupytext Sync extension for VS Code (#​1411, vscode-jupytext-sync-#​12). When such a synchronous modification is detected, Jupytext now raises an error. Many thanks to Anne Archibald for reporting the issue and preparing an inspiring PR (#​1417).
• We don't import notebook when jupyter_server is available (#​1436)
• Jupytext now supports more characters in the cell metadata keys, to improve compatibility with jupyterlab-slideshow (#​1441). Thanks to Nicolas Thierry for this fix.
• The function find_jupytext_configuration_file now works with relative directories (#​1440). This fix was contributed by Thierry Parmentelat.
• We have fixed a parsing error for R Markdown files (#​1429)
• We have fixed a parsing error when the first cell of the notebook contains a YAML header that is not a dict (#​1444)

Changed

• We have updated the pre-commit hooks. The code is now formatted using ruff format, and updated for Python 3.9+ using https://github.com/asottile/pyupgrade (#​1423)
