# Eclipse Zenoh

The Eclipse Zenoh: Zero Overhead Pub/sub, Store/Query and Compute.

Zenoh (pronounce _/zeno/_) unifies data in motion, data at rest and computations. It carefully blends traditional pub/sub with geo-distributed storages, queries and computations, while retaining a level of time and space efficiency that is well beyond any of the mainstream stacks.

Check the website [zenoh.io](http://zenoh.io) and the [roadmap](https://github.com/eclipse-zenoh/roadmap) for more detailed information.

-------------------------------

# Python API

This repository provides a Python binding based on the main [Zenoh implementation written in Rust](https://github.com/eclipse-zenoh/zenoh).

-------------------------------

## How to install it

The Eclipse zenoh-python library is available on [Pypi.org](https://pypi.org/project/eclipse-zenoh/).
Install the latest available version using `pip` in a [virtual environment](https://packaging.python.org/en/latest/guides/installing-using-pip-and-virtual-environments/):

```bash
pip install eclipse-zenoh
```

:warning:WARNING:warning: zenoh-python is developped in Rust.
On Pypi.org we provide binary wheels for the most common platforms (Linux x86_64, i686, ARMs, MacOS universal2 and Windows amd64). But also a source distribution package for other platforms.
However, for `pip` to be able to build this source distribution, there are some prerequisites:

- `pip` version 19.3.1 minimum (for full support of PEP 517).
   (if necessary upgrade it with command: `'sudo pip install --upgrade pip'` )
- Have a Rust toolchain installed (instructions at [rustup.rs](https://rustup.rs/))

### Supported Python versions and platforms

zenoh-python has been tested with Python 3.8, 3.9, 3.10, 3.11 and 3.12

It relies on the [zenoh](https://github.com/eclipse-zenoh/zenoh/tree/main/zenoh) Rust API which require the full `std` library. See the list in [Rust Platform Support](https://doc.rust-lang.org/nightly/rustc/platform-support.html).

### Enable zenoh features

To enable some compilation features of the Rust library that are disabled by default, for example `shared-memory`, execute the following command:

```bash
pip install eclipse-zenoh --no-binary :all: --config-settings build-args="--features=zenoh/shared-memory"
```

-------------------------------

## How to build it

Requirements:

- Python >= 3.8
- pip >= 19.3.1
- (Optional) A Python virtual environment (for instance [virtualenv](https://docs.python.org/3.10/tutorial/venv.html) or [miniconda](https://docs.conda.io/en/latest/miniconda.html))
- [Rust and Cargo](https://doc.rust-lang.org/cargo/getting-started/installation.html). If you already have the Rust toolchain installed, make sure it is up-to-date with:

   ```bash
   rustup update
   ```

Steps:

- Install developments requirements:

   ```bash
   pip install -r requirements-dev.txt
   ```

- Ensure your system can find the building tool `maturin` (installed by previous step).
  For example, it is placed at _$HOME/.local/bin/maturin_ by default on Ubuntu 20.04.

   ```bash
   export PATH="$HOME/.local/bin:$PATH"
   ```

- Build and install zenoh-python:

  - With a virtual environment active:

     ```bash
     maturin develop --release
     ```

  - Without one:

     ```bash
     maturin build --release
     pip install ./target/wheels/<there should only be one .whl file here>
     ```

-------------------------------

## Running the Examples

You can install Zenoh Router first (See [the instructions](https://github.com/eclipse-zenoh/zenoh/?tab=readme-ov-file#how-to-install-it)).
Then, run the zenoh-python examples following the instructions in [examples/README.md](https://github.com/eclipse-zenoh/zenoh-python/tree/main/examples#readme)
