Inclusive Kinematic Fit provides code to kinematically fit the four momenta of the tag-side B meson, the signal lepton and the inclusive X system in inclusive semi-leptonic B decays ast e+e- B factories like Belle II.

To install the dependencies of the package simply run

# setup your basf2 environment release in which you want to install this package
pip3 install --upgrade pip
pip3 install --upgrade --editable .

An additional --user argument is required if you don't have writing rights to your basf2 externals, e.g. if you use a basf2 release from cvmfs, so pip will then install the package into your ~/.local directory.

If you just want to import functions from it, you don't need anything else, but if you want to work on the code, and submit PR's, you should run:

pip3 install -r requirements-dev.txt
pre-commit install

The pip command will install some code linters and formatters that check if the style of your code conforms to the project rule, e.g.pylint and pre-commit. The second line install the git hooks to check your code before creating a commit.

To check your code without trying to commit you can just run pre-commit run --all or just run black <filename.py>.

pytest is used to create and run unit tests. Please ensure new code has a corresponding test suite that runs succesfully. You can run the tests via

pytest

in the package root directory.
