This module contains miscellaneous utility functions that can be applied in a
variety of circumstances; there are context managers, membership functions
(test if an argument is of a given type), numerical functions, string
functions and functions to aid in the unit testing of modules

`Pytest`_ is the supported test runner

Interpreter
===========

The package has been developed and tested with Python 2.7, 3.5, 3.6 and 3.7
under Linux (Debian, Ubuntu), Apple macOS and Microsoft Windows

Installing
==========

.. code-block:: console

$ pip install pmisc

Documentation
=============

Available at `Read the Docs <https://pmisc.readthedocs.io>`_

Contributing
============

1. Abide by the adopted `code of conduct
<https://www.contributor-covenant.org/version/1/4/code-of-conduct>`_

2. Fork the `repository <https://github.com/pmacosta/pmisc>`_ from GitHub and
then clone personal copy [#f1]_:

.. code-block:: console

$ github_user=myname
$ git clone --recurse-submodules \
https://github.com/"${github_user}"/pmisc.git
Cloning into 'pmisc'...
...
$ cd pmisc || exit 1
$ export PMISC_DIR=${PWD}
$

3. The package uses two sub-modules: a set of custom Pylint plugins to help with
some areas of code quality and consistency (under the ``pylint_plugins``
directory), and a lightweight package management framework (under the
``pypkg`` directory). Additionally, the `pre-commit framework
<https://pre-commit.com/>`_ is used to perform various pre-commit code
quality and consistency checks. To enable the pre-commit hooks:

.. code-block:: console

$ cd "${PMISC_DIR}" || exit 1
$ pre-commit install
pre-commit installed at .../pmisc/.git/hooks/pre-commit
$

4. Ensure that the Python interpreter can find the package modules
(update the :bash:`$PYTHONPATH` environment variable, or use
`sys.paths() <https://docs.python.org/3/library/sys.html#sys.path>`_,
etc.)

.. code-block:: console

$ export PYTHONPATH=${PYTHONPATH}:${PMISC_DIR}
$

5. Install the dependencies (if needed, done automatically by pip):


* `Cog`_ (2.5.1 or newer)

* `Coverage`_ (4.5.3 or newer)

* `Decorator`_ (4.4.0 or newer)

* `Docutils`_ (0.14 or newer)

* `Funcsigs`_ (1.0.2 or newer)

* `Inline Syntax Highlight Sphinx Extension`_ (0.2 or newer)

* `Mock`_ (2.0.0 or newer)

* `Numpy`_ (1.16.2 or newer)

* `Pydocstyle`_ (3.0.0 or newer)

* `Pylint`_ (Python 2.x: 1.9.4 or newer, Python 3.x: 2.3.1 or newer)

* `Pytest`_ (4.3.1 or newer)

* `Pytest-coverage`_ (2.6.1 or newer)

* `Pytest-xdist`_ (optional, 1.26.1 or newer)

* `ReadTheDocs Sphinx theme`_ (0.4.3 or newer)

* `Shellcheck Linter Sphinx Extension`_ (1.0.8 or newer)

* `Sphinx`_ (1.8.5 or newer)

* `Tox`_ (3.7.0 or newer)

* `Virtualenv`_ (16.4.3 or newer)

6. Implement a new feature or fix a bug

7. Write a unit test which shows that the contributed code works as expected.
Run the package tests to ensure that the bug fix or new feature does not
have adverse side effects. If possible achieve 100\% code and branch
coverage of the contribution. Thorough package validation
can be done via Tox and Pytest:

.. code-block:: console

$ PKG_NAME=pmisc tox
GLOB sdist-make: .../pmisc/setup.py
py27-pkg create: .../pmisc/.tox/py27
py27-pkg installdeps: -r.../pmisc/requirements/tests_py27.pip, -r.../pmisc/requirements/docs_py27.pip
...
py27-pkg: commands succeeded
py35-pkg: commands succeeded
py36-pkg: commands succeeded
py37-pkg: commands succeeded
congratulations :)
$

`Setuptools <https://bitbucket.org/pypa/setuptools>`_ can also be used
(Tox is configured as its virtual environment manager):

.. code-block:: console

$ PKG_NAME=pmisc python setup.py tests
running tests
running egg_info
writing pmisc.egg-info/PKG-INFO
writing dependency_links to pmisc.egg-info/dependency_links.txt
writing requirements to pmisc.egg-info/requires.txt
...
py27-pkg: commands succeeded
py35-pkg: commands succeeded
py36-pkg: commands succeeded
py37-pkg: commands succeeded
congratulations :)
$

Tox (or Setuptools via Tox) runs with the following default environments:
``py27-pkg``, ``py35-pkg``, ``py36-pkg`` and ``py37-pkg`` [#f3]_. These use
the 2.7, 3.5, 3.6 and 3.7 interpreters, respectively, to test all code in
the documentation (both in Sphinx ``*.rst`` source files and in
docstrings), run all unit tests, measure test coverage and re-build the
exceptions documentation. To pass arguments to Pytest (the test runner) use
a double dash (``--``) after all the Tox arguments, for example:

.. code-block:: console

$ PKG_NAME=pmisc tox -e py27-pkg -- -n 4
GLOB sdist-make: .../pmisc/setup.py
py27-pkg inst-nodeps: .../pmisc/.tox/.tmp/package/1/pmisc-1.5.7.zip
...
py27-pkg: commands succeeded
congratulations :)
$

Or use the :code:`-a` Setuptools optional argument followed by a quoted
string with the arguments for Pytest. For example:

.. code-block:: console

$ PKG_NAME=pmisc python setup.py tests -a "-e py27-pkg -- -n 4"
running tests
...
py27-pkg: commands succeeded
congratulations :)
$

There are other convenience environments defined for Tox [#f3]_:

* ``py27-repl``, ``py35-repl``, ``py36-repl`` and ``py37-repl`` run the
Python 2.7, 3.5, 3.6 and 3.7 REPL, respectively, in the appropriate
virtual environment. The ``pmisc`` package is pip-installed by Tox when
the environments are created. Arguments to the interpreter can be
passed in the command line after a double dash (``--``).

* ``py27-test``, ``py35-test``, ``py36-test`` and ``py37-test`` run Pytest
using the Python 2.7, 3.5, 3.6 and 3.7 interpreter, respectively, in the
appropriate virtual environment. Arguments to pytest can be passed in
the command line after a double dash (``--``) , for example:

.. code-block:: console

$ PKG_NAME=pmisc tox -e py27-test -- -x test_pmisc.py
GLOB sdist-make: .../pmisc/setup.py
py27-pkg inst-nodeps: .../pmisc/.tox/.tmp/package/1/pmisc-1.5.7.zip
...
py27-pkg: commands succeeded
congratulations :)
$
* ``py27-test``, ``py35-test``, ``py36-test`` and ``py37-test`` test code
and branch coverage using the 2.7, 3.5, 3.6 and 3.7 interpreter,
respectively, in the appropriate virtual environment. Arguments to
pytest can be passed in the command line after a double dash (``--``).
The report can be found in :bash:`${PMISC_DIR}/.tox/py[PV]/usr/share/pmi
sc/tests/htmlcov/index.html` where ``[PV]`` stands for ``2.7``, ``3.5``,
``3.6`` or ``3.7`` depending on the interpreter used.

8. Verify that continuous integration tests pass. The package has continuous
integration configured for Linux, Apple macOS and Microsoft Windows (all via
`Azure DevOps <https://dev.azure.com/pmasdev>`_).

9. Document the new feature or bug fix (if needed). The script
:bash:`${PMISC_DIR}/pypkg/build_docs.py` re-builds the whole package
documentation (re-generates images, cogs source files, etc.):


.. code-block:: console

$ "${PMISC_DIR}"/pypkg/build_docs.py -h
usage: build_docs.py [-h] [-d DIRECTORY] [-r]
[-n NUM_CPUS] [-t]

Build pmisc package documentation

optional arguments:
-h, --help show this help message and exit
-d DIRECTORY, --directory DIRECTORY
specify source file directory
(default ../pmisc)
-r, --rebuild rebuild exceptions documentation.
If no module name is given all
modules with auto-generated
exceptions documentation are
rebuilt
-n NUM_CPUS, --num-cpus NUM_CPUS
number of CPUs to use (default: 1)
-t, --test diff original and rebuilt file(s)
(exit code 0 indicates file(s) are
identical, exit code 1 indicates
file(s) are different)
