# EEA Faceted Navigation

## Documentation

Trainings on how to create your own website using Plone 6 is available as part of the Plone training at [https://training.plone.org](https://training.plone.org).

## Pre-requirements

* Python **3.7, 3.8, 3.9**
* Python **python-venv** and **python-dev**
* Node 16 / Yarn (See https://6.dev-docs.plone.org/volto/getting-started)
* Libraries
  - **libz**
  - **libjpeg**
  - **readline**
  - **libexpat**
  - **libssl** or **openssl**
  - **libxml2**
  - **libxslt**

### Ubuntu / Debian / Windows Bash

**Note** If you already have a higher version of python on your system, replace **python3.8** with your installed version bellow

    apt update
    apt install python3-venv python3.8-dev python3.8-venv git make gcc

Optionally set default `python3`:

    update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.8 1

### Mac OS

    brew install zlib git readline jpeg libpng libyaml


## Install

In order to develop Plone 6 backend add-on run:

    git clone https://github.com/eea/eea.facetednavigation
    cd eea.facetednavigation
    make
    make start

To use other **Python** version run make with `-e` parameter:

    make -e PYTHON=python3.8
    make start

To use other **Plone** version run make with `-e` parameter:

    make -e PLONE_VERSION=5.2.9
    make start

## CSS / JS Resources

CSS and JS static resources are automatically built on `make start` but you can always manually rebuild them by running:

    yarn
    yarn build

See the `resources` directory if you need to add or remove CSS/JS resources.

See `webpack.config.js` and `package.json` for the static resources input/output options.

## Develop

Run:

    make develop

We recommend using [Visual Studio Code](https://code.visualstudio.com/) Editor
* Extensions:
  * [Remote Development](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.vscode-remote-extensionpack) - Windows only
  * [Python](https://marketplace.visualstudio.com/items?itemName=ms-python.python)
* Open Visual Studio Code and click **File > Open Folder**
* Browser your computer and select **eea.facetednavigation**
* Within the **Explorer** open `eea > facetednavigaton > interfaces.py` and type
  `from zope.component import query`. If you get the auto-complete options, you're done.
* Happy hacking!

**Note** `Hot reload` is not available for Plone backend development, thus you'll have to **restart** Plone after you edit Python code. Still, there are options to reload your changes without restarting Plone, by using `plone.reload` and `dm.plonepatches.reload`. Go to http://localhost:8080/@@reload `admin:admin`

### Useful Visual Studio Code shortcuts

**Note** Replace `Ctrl` with `Cmd` key on MacOS

* **Ctrl+Shift+P** Trim Trailing Whitespace
* **Ctrl+Shift+P** Sort imports
* **Ctrl+click** on a `class / import` to go to definition


## Testing

You can manually run test in terminal, like:

    bin/zope-testrunner --test-path eea

Or via `Visual Studio Code`
* Go to `Run > Start Debugging (F5)` and select `Test Plone` debugger.

## Cleanup

If you want to cleanup your development environment and start from scratch just run:

    make clean
