# OpenFisca Nouvelle Calédonie

This repository helps you quickly set up and use your own OpenFisca country
package.

**You should NOT fork it** but follow the set up instructions below.

> Otherwise, you will have to clean up all tags when you deploy your own
> country package.

## Setting up your Country Package

This set of instructions **only needs to be followed once** and will create
your own copy of this boilerplate directory, customising it to the country you
want to work on. You will need to have [Git](https://git-scm.com) installed.

### Using GitHub (recommended for GitHub users)

1. Click on the
   [“Use this template” dropdown and select “Create a new repository”](https://github.com/new?template_name=country-template&template_owner=openfisca).

2. Set the repository name to `openfisca-<your_country_name>`; use underscore
   `_` as separator if there are spaces in the country name. For example,
   `openfisca-new_zealand` or `openfisca-france`.

3. After being redirected to your newly created repository, please allow a few
   minutes for the automatic setup to be executed. Once done, the title of the
   README file should be updated to `OpenFisca <your_country_name>`.

> If the automatic setup does not start within a few minutes, you can initiate
> it manually:
>
> - Navigate to the “Actions” tab.
> - Select the “First time setup” workflow.
> - Click on “Run workflow” to start the setup process manually.

4. Follow the instructions in the new repository's README.md.

### Manual setup (recommended for users of other Git hosts)

1. [Download a copy](https://github.com/openfisca/country-template/archive/master.zip)
   of this repository, unzip it and `cd` into it in a Terminal window.

2. Create a new repository on your favourite git host (Bitbucket, GitLab, …)
   with the name `openfisca-<your_country_name>`. For example,
   `openfisca-new_zealand` or `openfisca-france`.

3. Execute the `first-time-setup.sh` script to initialise the git repository.
   This performs numerous tasks including replacing all references to
   `openfisca-country_template` with references to the new country package.

   - To execute the script run `bash first-time-setup.sh` from the command line
   - After the `first-time-setup.sh` has run both it and these instructions are
     removed.

4. Follow the instructions in the new repository's `README.md.`

## Writing the Legislation

The country whose law is modelled here has a very simple tax and benefit
system.

- It has a flat rate tax whose rates increase every year.
- On the first of December, 2015, it introduced a basic income for all its
  citizens of age who have no income.
- On the first of December, 2016, it removed the income condition, providing
  all its adult citizens with a basic income.

These elements are described in different folders. All the modelling happens
within the `openfisca_country_template` folder.

- The rates are in the `parameters` folder.
- The formulas are in the `variables` folder.
- This country package comes also with *reforms* in the `reforms` folder. This
  is optional: your country may exist without defining any reform.
  - In this country, there is
    [a reform project](./openfisca_country_template/reforms/modify_social_security_taxation.py)
    aiming to modify the social security taxation, deleting the first bracket,
    raising the intermediary ones and adding a new bracket with a higher tax
    rate of `40 %` for people earning more than `40000`. This reform project
    would apply starting from `2017-01-01`.

The files that are outside from the `openfisca_country_template` folder are
used to set up the development environment.

## Packaging your Country Package for Distribution

Country packages are Python distributions. You can choose to distribute your
package automatically via the predefined continuous deployment system on GitHub
Actions, or manually.

### Automatic continuous deployment on GitHub

This repository is configured with a continuous deployment system to automate
the distribution of your package via `pip`.

#### Setting up continuous deployment

To activate the continuous deployment:

1. Create an account on [PyPI](https://pypi.org/) if you don't already have
   one.
2. Generate a token in your PyPI account. This token will allow GitHub Actions
   to securely upload new versions of your package to PyPI.
3. Add this token to your GitHub repository's secrets under the name
   `PYPI_TOKEN`.

Once set up, changes to the `main` branch will trigger an automated workflow to
build and publish your package to PyPI, making it available for `pip`
installation.

### Manual distribution

If you prefer to manually manage the release and distribution of your package,
follow the guidelines provided by the
[Python Packaging Authority](https://python-packaging-user-guide.readthedocs.io/tutorials/distributing-packages/#packaging-your-project).

This involves detailed steps on preparing your package, creating distribution
files, and uploading them to PyPI.

## Install Instructions for Users and Contributors

This package requires
[Python 3.11](https://www.python.org/downloads/release/python-390/). More
recent versions should work, but are not tested.

All platforms that can execute Python are supported, which includes GNU/Linux,
macOS and Microsoft Windows.

### Setting-up a Virtual Environment with venv

In order to limit dependencies conflicts, we recommend using a
[virtual environment](https://www.python.org/dev/peps/pep-0405/) with
[venv](https://docs.python.org/3/library/venv.html).

- A [venv](https://docs.python.org/3/library/venv.html) is a project specific
  environment created to suit the needs of the project you are working on.

To create a virtual environment, launch a terminal on your computer, `cd` into
your directory and follow these instructions:

```sh
python3 -m venv .venv # create a new virtual environment in the “.venv” folder, which will contain all dependencies
source .venv/bin/activate # activate the venv
```

You can now operate in the venv you just created.

You can deactivate that venv at any time with `deactivate`.

:tada: You are now ready to install this OpenFisca Country Package!

Two install procedures are available. Pick procedure A or B below depending on
how you plan to use this Country Package.

- contribute to the source code.

_Note: This tutorial assumes you have already followed the instructions laid
out in section [B. Advanced Installation](#b-advanced-installation-git-clone)._

In order to ensure all published versions of this template work as expected,
new contributions are tested in an isolated manner on Github Actions.

Follow these steps to set up an isolated environment for testing your
contributions as Github Actions does.

#### Set up an isolated environment

First, make sur [Tox](https://tox.wiki/en/4.23.0/) is installed on your
machine.

We recommend using [pipx](<(https://pypi.org/project/pipx/)>) to install `tox`,
to avoid mixing isolated-testing dependencies testing with `virtualenv`.

```sh
pipx install tox
```

#### Testing your contribution in an isolated environment
