*Tools for comparing different versions of a Capella model*

# Quick start

Run the `capella-diff-tool` with a Git repo and two versions, being either
commit hashes or branch names:

```sh
capella-diff-tool coffee-machine index-links/base index-links/left
```

```yaml

The CLI's first argument accepts the name of a [known model], a local folder,
or JSON describing a remote model. Currently it only supports Git, but a
[Python API] is available for more advanced comparisons.

[known model]: https://dsd-dbs.github.io/py-capellambse/start/specifying-models.html#known-models
[Python API]: #api-documentation

The `capella-diff-tool` can also generate a human-friendly report in HTML form.
Use the `-r` / `--report` flag and specify a filename to write the HTML report:

```sh
capella-diff-tool coffee-machine index-links/base index-links/left -r coffee-machine.html
```

# Installation

You can install the latest released version directly from PyPI.

```sh
pip install capella-diff-tools
```

To set up a development environment, clone the project and install it into a
virtual environment.

```sh
git clone https://github.com/DSD-DBS/capella-diff-tools
cd capella-diff-tools
python -m venv .venv

source .venv/bin/activate.sh  # for Linux / Mac
.venv\Scripts\activate  # for Windows

pip install -U pip pre-commit
pip install -e '.[docs,test]'
pre-commit install
```

# API Documentation

The `capella_diff_tools` Python package exposes a Python API, which can be used
to compare arbitrary models programmatically. Documentation for this API is
[available on Github pages](https://dsd-dbs.github.io/capella-diff-tools).
