This library integrates closely and libpython-clj and uv.
It provides a single function, 'libpython-clj-uv.sync/sync-python-setup!
which can be hooked into the startup of libpython-clj, by providing a file
python.edn containing:
{
:python-version"3.14.0":python-deps ["polars==1.37.1"]
:python-executable".venv/bin/python";; in Linux;; :python-executable ".venv/Script/python ;; in Windows:pre-initialize-fn libpython-clj-uv.sync/sync-python-setup!
}
This will call the function 'libpython-clj-uv.sync/sync-python-setup! on JVM start, which will use the information in python.edn to create a
pyproject.toml file and then run uv sync (which itself uses then the generated pyproject.toml file to create/sync a python venv in folder .venv)
uv needs to be installed for this to work.
It will take the python libraries to install from key :python-deps (the strings have the same syntax then in pyproject.toml, see uv documentation) and installs the python version defined in :python-version.
So it basically allows to define a pyproject.toml using python.edn
The pyproject.toml will be overwritten by each JVM start.
libpython-clj is then guarantied to use the created venv.
This guaranties that the venv is in sync and existing before libpython-clj gets initialized.
