# higlass-python 🔎

A fresh Python library for [`higlass`](https://github.com/higlass/higlass) built
on top of [`higlass-schema`](https://github.com/higlass/higlass-schema) and
[anywidget](https://github.com/manzt/anywidget).

[![License](https://img.shields.io/pypi/l/higlass-python.svg?color=green)](https://github.com/higlass/higlass-python/raw/main/LICENSE)
[![Open In Colab](https://colab.research.google.com/assets/colab-badge.svg)](https://colab.research.google.com/github/higlass/higlass-python/blob/main/examples/Examples.ipynb)

## Installation

```sh
pip install higlass-python
```

## Usage

```python
import higlass as hg

# Remote data source (tileset)
tileset1 = hg.remote(
    uid="CQMd6V_cRw6iCI_-Unl3PQ",
    server="https://higlass.io/api/v1/",
    name="Rao et al. (2014) GM12878 MboI (allreps) 1kb",
)

# Local tileset
tileset2 = hg.cooler("../data/dataset.mcool")

# Create a `hg.HeatmapTrack` for each tileset
track1 = tileset1.track("heatmap")
track2 = tileset2.track("heatmap")

# Create two independent `hg.View`s, one for each heatmap
view1 = hg.view(track1, width=6)
view2 = hg.view(track2, width=6)

# Lock zoom & location for each `View`
view_lock = hg.lock(view1, view2)

# Concatenate views horizontally and apply synchronization lock
(view1 | view2).locks(view_lock)
```

To learn more about the new API, check out the
[updated documentation](http://docs-python.higlass.io/).

## Upgrade Guide

**higlass-python** v1.0 is a total rewrite of our prior implementation, aimed to
offer a more ergonomic and flexible API. While this might present challenges
when upgrading existing code, we've prepared
[documentation](http://docs-python.higlass.io/) to guide you through the new API
usage.

If you find a missing feature, please open an issue – we're committed to
supporting your use cases with the new API.

Despite the large changes in v1.0, we will strive to avoid breaking changes
going forward. However, because of the complete rewrite, the v1.0 release
doesn't strictly adhere to semantic versioning. You can think of it as a pre-1.0
release, with breaking changes and new features included in minor releases, and
bug fixes in patch releases.

We will aim for strict semantic versioning with the v2.0 release. Your feedback
and understanding are greatly appreciated.

## Development

**higlass-python** is primarily a Python project, but it includes JavaScript for
the anywidget-based front-end code (`src/higlass/widget.js`). We use
[uv](https://github.com/astral-sh/uv) for Python development and
[deno](https://github.com/denoland/deno) for linting and type-checking
JavaScript.

All formatting, linting, and tests are enforced in CI.

### Commands Cheatsheet

All commands are run from the root of the project, from a terminal:

## Changelog

Check the [GitHub Releases](https://github.com/higlass/higlass-python/releases)
for a detailed changelog.

## Release

Releases are managed via the GitHub UI.

[Draft a new release](https://github.com/higlass/higlass-python/releases/new):

1. **Create a tag**

- Click _"Choose a tag"_, then **type a new tag** in the format
     `v[major].[minor].[patch]` to create it.
   - _Note_: The UI is not obvious about this. You can create a tag here, not
     just select one. Tag creation triggers a
     [workflow](.github/workflows/ci.yml) to publish to PyPI.

2. **Generate release notes**

- Click _"Generate Release Notes"_ to auto-summarize changes from merged PRs.
   - Edit to exclude irrelevant changes for end users (e.g., docs or CI).

3. **Document significant changes**
   - Add migration steps or noteworthy updates.
   - Ensure PR titles are clear and consistent.
