Serenata de Amor Toolbox

pip <https://pip.pypa.io/en/stable/>_ installable package to support Serenata de Amor <https://github.com/okfn-brasil/serenata-de-amor>_ and Rosie <https://github.com/okfn-brasil/serenata-de-amor/blob/master/rosie/README.md>_ development.

Serenata_toolbox is compatible with Python 3.6+

Installation

.. code-block:: bash

$ pip install -U serenata-toolbox

If you are a regular user you are ready to get started after pip install.

If you are a core developer willing to upload datasets to the cloud you need to configure AMAZON_ACCESS_KEY and AMAZON_SECRET_KEY environment variables before running the toolbox.

Usage

We have plenty of them <https://github.com/okfn-brasil/serenata-de-amor/blob/51fad8c807cb353303c5f5a3f945693feeb82015/CONTRIBUTING.md#datasets-researchdata>_ ready for you to download from our servers. And this toolbox helps you get them. Here some examples:

Example 1: Using the command line wrapper ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

.. code-block:: bash

# without any arguments will download our pre-processed datasets and store into data/ folder
$ serenata-toolbox

# will download these specific datasets and store into /tmp/serenata-data folder
$ serenata-toolbox /tmp/serenata-data --module federal_senate chamber_of_deputies

# you can specify a dataset and a year
$ serenata-toolbox --module chamber_of_deputies --year 2009

# or specify all options simultaneously
$ serenata-toolbox /tmp/serenata-data --module federal_senate --year 2017

# getting help
$ serenata-toolbox --help

Example 2: How do I download the datasets? ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Another option is creating your own Python script:

.. code-block:: python

from serenata_toolbox.datasets import Datasets datasets = Datasets('data/')

now lets see what are the latest datasets available

for dataset in datasets.downloader.LATEST: print(dataset) # and you'll see a long list of datasets!

and let's download one of them

datasets.downloader.download('2018-01-05-reimbursements.xz') # yay, you've just downloaded this dataset to data/

you can also get the most recent version of all datasets:

latest = list(datasets.downloader.LATEST) datasets.downloader.download(latest)

Example 3: Using shortcuts ^^^^^^^^^^^^^^^^^^^^^^^^^^

If the last example doesn't look that simple, there are some fancy shortcuts available:

.. code-block:: python

from serenata_toolbox.datasets import fetch, fetch_latest_backup fetch('2018-01-05-reimbursements.xz', 'data/') fetch_latest_backup( 'data/') # yep, we've just did exactly the same thing

Example 4: Generating datasets ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

If you ever wonder how did we generated these datasets, this toolbox can help you too (at least with the more used ones — the other ones are generated in our main repo <https://github.com/okfn-brasil/serenata-de-amor/blob/51fad8c807cb353303c5f5a3f945693feeb82015/CONTRIBUTING.md#the-toolbox-and-our-the-source-files-researchsrc>_):

.. code-block:: python

from serenata_toolbox.federal_senate.dataset import Dataset as SenateDataset
from serenata_toolbox.chamber_of_deputies.reimbursements import Reimbursements as ChamberDataset

chamber = ChamberDataset('2018', 'data/')
chamber()

senate = SenateDataset('data/')
senate.fetch()
senate.translate()
senate.clean()

Documentation (WIP)

The full documentation <https://serenata-toolbox.readthedocs.io>_ is still a work in progress. If you wanna give us a hand you will need Sphinx <http://www.sphinx-doc.org/>_:

.. code-block:: bash

$ cd docs $ make clean;make rst;rm source/modules.rst;make html

Contributing

Firstly, you should create a development environment with Python's venv <https://docs.python.org/3/library/venv.html#creating-virtual-environments>_ module to isolate your development. Then clone the repository and build the package by running:

.. code-block:: bash

$ git clone https://github.com/okfn-brasil/serenata-toolbox.git $ cd serenata-toolbox $ python setup.py develop

Always add tests to your contribution — if you want to test it locally before opening the PR:

.. code-block:: bash

$ pip install tox $ tox

When the tests are passing, also check for coverage of the modules you edited or added — if you want to check it before opening the PR:

.. code-block:: bash

$ tox $ open htmlcov/index.html

Follow PEP8 <https://www.python.org/dev/peps/pep-0008/>_ and best practices implemented by Landscape <https://landscape.io>_ in the veryhigh strictness level — if you want to check them locally before opening the PR:

.. code-block:: bash

$ pip install prospector $ prospector -s veryhigh serenata_toolbox

If this report includes issues related to import section of your files, isort <https://github.com/timothycrosley/isort>_ can help you:

.. code-block:: bash

$ pip install isort $ isort **/*.py --diff

Always suggest a version bump. We use Semantic Versioning <http://semver.org>_ – or in Elm community words <https://github.com/elm-lang/elm-package#version-rules>_:

  • MICRO: the API is the same, no risk of breaking code
  • MINOR: values have been added, existing values are unchanged
  • MAJOR: existing values have been changed or removed

This is really important because every new code merged to master triggers the CI and then the CI triggers a new release to PyPI. The attemp to roll out a new version of the toolbox will fail without a version bump. So we do encorouge to add a version bump even if all you have changed is the README.rst — this is the way to keep the README.rst updated in PyPI.

If you are not changing the API or README.rst in any sense and if you really do not want a version bump, you need to add [skip ci] to you commit message.

And finally take The Zen of Python into account:

.. code-block:: bash

$ python -m this
