[[Full documentation]](https://icecube.github.io/skyllh/).

The SkyLLH framework is an open-source Python3-based package licensed under the
GPLv3 license. It provides a modular framework for implementing custom
likelihood functions and executing log-likelihood ratio hypothesis tests.
The idea is to provide a class structure tied to the mathematical objects of the
likelihood functions, rather than to entire abstract likelihood models.

The math formalism used in SkyLLH is described in the
[[math formalism document]](https://github.com/icecube/skyllh/blob/master/doc/user_manual.pdf).

# Installation

## Using pip

The latest `skyllh` release can be installed from
[PyPI](https://pypi.org/project/skyllh/) repository:
```bash
pip install skyllh
```

The current development version can be installed using pip:
```bash
pip install git+https://github.com/icecube/skyllh.git#egg=skyllh
```

Optionally, the editable package version with a specified reference can be
installed by:
```bash
pip install -e git+https://github.com/icecube/skyllh.git@[ref]#egg=skyllh
```
where
- `-e` is an editable flag
- `[ref]` is an optional argument containing a specific commit hash, branch name
  or tag

## Cloning from GitHub

The `skyllh` (and an optional private [i3skyllh](#i3skyllh)) package can be
installed by cloning the GitHub repository and adding it to the Python path:

```python
import sys

sys.path.insert(0, '/path/to/skyllh')
sys.path.insert(0, '/path/to/i3skyllh')  # optional
```

# Publications

Several publications about the SkyLLH software are available:

- IceCube Collaboration, C. Bellenghi, M. Karl, M. Wolf, et al. PoS ICRC2023 (2023) 1061

# Developer Guidelines

These guidelines should help new developers of SkyLLH to join the development
process easily.

## Code style

- The code follows PEP8 coding style guidelines as close as possible.

- Code lines are maximum 80 characters wide.

- 4 spaces are used as one indentation level.

## Branching

- When implementing a new feature / change, first an issue must be created
  describing the new feature / change. Then a branch must be created referring
  to this issue. We recommend the branch name `fix<ISSUE_NUMBER>`, where
  `<ISSUE_NUMBER>` is the number of the created issue for this feature / change.

- In cases when SkyLLH needs to be updated because of a change in the i3skyllh
  package (see below), we recommend the branch name `i3skyllh_<ISSUE_NUMBER>`,
  where `<ISSUE_NUMBER>` is the number of the issue created in the i3skyllh
  repository. That way the *analysis unit tests* workflow will be able to find
  the correct skyllh branch corresponding to the i3skyllh change automatically.

## Releases and Versioning

- Release version numbers follow the format `v<YY>.<MAJOR>.<MINOR>`, where
  `<YY>` is the current year, `<MAJOR>` and `<MINOR>` are the major and minor
  version numbers of type integer. Example: `v23.2.0`.

- Release candidates follow the same format as releases, but have the additional
  suffix `.rc<NUMBER>`,  where `<NUMBER>` is an integer starting with 1.
  Example: `v23.2.0.rc1`

- Before creating the release on github, the version number needs to be updated
  in the Sphinx documentation: `doc/sphinx/conf.py`.

# i3skyllh

The [`i3skyllh`](https://github.com/icecube/i3skyllh) package provides
complementary pre-defined common analyses and datasets for the
[IceCube Neutrino Observatory](https://icecube.wisc.edu) detector in a private
[repository](https://github.com/icecube/i3skyllh).
