Py-EthPM
========

`Join the chat at
https://gitter.im/ethpm/lobby <https://gitter.im/ethpm/lobby?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge>`__
`CircleCI <https://circleci.com/gh/ethpm/py-ethpm>`__ `PyPI
version <https://badge.fury.io/py/ethpm>`__

A Python implementation of the `Ethereum Package Manager
Specification <http://ethpm.github.io/ethpm-spec/package-spec.html>`__.

Read more in the documentation on
`ReadTheDocs <https://py-ethpm.readthedocs.io/en/latest/>`__.

WARNING!

``Py-EthPM`` is currently in public alpha. *Keep in mind*: - It is
expected to have bugs and is not meant to be used in production - Things
may be ridiculously slow or not work at all

Quickstart
----------

.. code:: sh

   pip install ethpm

Developer Setup
---------------

If you would like to hack on Py-EthPM, please check out the `Ethereum
Development Tactical
Manual <https://github.com/pipermerriam/ethereum-dev-tactical-manual>`__
for information on how we do:

-  Testing
-  Pull Requests
-  Code Style
-  Documentation

Developer Environment Setup
~~~~~~~~~~~~~~~~~~~~~~~~~~~

You can set up your dev environment with:

.. code:: sh

   git clone git@github.com:ethpm/py-ethpm.git
   cd py-ethpm
   virtualenv -p python3 venv
   . venv/bin/activate
   pip install -e .[dev]

Testing Setup
~~~~~~~~~~~~~

During development, you might like to have tests run on every file save.

Show flake8 errors on file change:

.. code:: sh

   # Test flake8
   when-changed -v -s -r -1 py-ethpm/ tests/ -c "clear; flake8 py-ethpm tests && echo 'flake8 success' || echo 'error'"

Run multi-process tests in one command, but without color:

.. code:: sh

   # in the project root:
   pytest --numprocesses=4 --looponfail --maxfail=1
   # the same thing, succinctly:
   pytest -n 4 -f --maxfail=1

Run in one thread, with color and desktop notifications:

.. code:: sh

   cd venv
   ptw --onfail "notify-send -t 5000 'Test failure ⚠⚠⚠⚠⚠' 'python 3 test on <REPO_NAME> failed'" ../tests ../<MODULE_NAME>

How to Execute the Tests?
^^^^^^^^^^^^^^^^^^^^^^^^^

1. `Setup your development
   environment <https://github.com/ethpm/py-ethpm/#developer-setup>`__.

2. Execute ``tox`` for the tests

There are multiple
`components <https://github.com/ethpm/py-ethpm/blob/master/.circleci/.config.yml#L56>`__
of the tests. You can run test to against specific component. For
example:

.. code:: sh

   # Run Tests for the Core component (for Python 3.5):
   tox -e py35

   # Run Tests for the Core component (for Python 3.6):
   tox -e py36

If for some reason it is not working, add ``--recreate`` params.

``tox`` is good for testing against the full set of build targets. But
if you want to run the tests individually, ``py.test`` is better for
development workflow. For example, to run only the tests in one file:

.. code:: sh

   pytest tests/ethpm/utils/test_uri_utils.py

IPFS integration tests (``tests/ethpm/integration/``) require a direct
connection to an IPFS node and are skipped by default (except in
CircleCI, where they are run). To include these tests in your test run,
first start an IPFS node and then add ``--integration`` to the pytest
command.

Release setup
~~~~~~~~~~~~~

For Debian-like systems:

::

   apt install pandoc

To release a new version:

.. code:: sh

   make release bump=$$VERSION_PART_TO_BUMP$$

How to bumpversion
^^^^^^^^^^^^^^^^^^

The version format for this repo is ``{major}.{minor}.{patch}`` for
stable, and ``{major}.{minor}.{patch}-{stage}.{devnum}`` for unstable
(``stage`` can be alpha or beta).

To issue the next version in line, specify which part to bump, like
``make release bump=minor`` or ``make release bump=devnum``.

If you are in a beta version, ``make release bump=stage`` will switch to
a stable.

To issue an unstable version when the current version is stable, specify
the new version explicitly, like
``make release bump="--new-version 4.0.0-alpha.1 devnum"``

EthPM-Spec
~~~~~~~~~~

-  ``EthPM-Spec <https://github.com/ethpm/ethpm-spec>``\ \_\_ is
   referenced inside this repo as a submodule.*\*
-  If you clone this repository, run this command to fetch the contents
   of the submodule

::

      git submodule init
