A set of python objects to represent physical objects for assessing structural and geotechnical problems

Attempting to solve the `Liskov Substitution Principle <https://en.wikipedia.org/wiki/Liskov_substitution_principle>`_
problem for combining independently developed source
code in the fields of structural and geotechnical engineering.


Installation
============

.. code:: bash
pip install sfsimodels

Saving and loading models
=========================

.. code-block:: python
structure = models.Structure() # Create a structure object
structure.id = 1 # Assign it an id
structure.name = "sample building" # Assign it a name and other parameters
structure.h_eff = 10.0
structure.t_fixed = 1.0
structure.mass_eff = 80000.
structure.mass_ratio = 1.0 # Set vertical and horizontal masses are equal

ecp_output = files.Output() # Create an output object
ecp_output.add_to_dict(structure) # Add the structure to the output object
ecp_output.name = "test data"
ecp_output.units = "N, kg, m, s" # Set the units
ecp_output.comments = ""

p_str = json.dumps(ecp_output.to_dict(), skipkeys=["__repr__"], indent=4) # Assign it to a json string
objs = files.loads_json(p_str) # Load a json string and convert to a dictionary of objects
assert ct.isclose(structure.mass_eff, objs['buildings'][1].mass_eff) # Access the object


How do I get set up?
====================

1. Run ``pip install -r requirements.txt``

Testing
=======

Tests are run with pytest

* Locally run: ``pytest`` on the command line.

* Tests are run on every push using travis, see the ``.travis.yml`` file


Deployment
==========

To deploy the package to pypi.com you need to:

1. Push to the *pypi* branch. This executes the tests on circleci.com

2. Create a git tag and push to github, run: ``trigger_deploy.py`` or manually:

.. code:: bash
git tag 0.5.2 -m "version 0.5.2"
git push --tags origin pypi
