`APRSD <http://github.com/craigerl/aprsd>`_ is a Ham radio `APRS <http://aprs.org>`_ message command gateway built on python.


What is APRSD
=============
APRSD is a python application for interacting with the APRS network and providing
APRS services for HAM radio operators.

APRSD currently has 4 main commands to use.
    * server - Connect to APRS and listen/respond to APRS messages
    * webchat - web based chat program over APRS
    * send-message - Send a message to a callsign via APRS_IS.
    * listen - Listen to packets on the APRS-IS Network based on FILTER.

Each of those commands can connect to the APRS-IS network if internet connectivity
is available.  If internet is not available, then APRS can be configured to talk
to a TCP KISS TNC for radio connectivity.

Please `read the docs`_ to learn more!

Typical use case
================

APRSD's typical use case is that of providing an APRS wide service to all HAM
radio operators.  For example the callsign 'REPEAT' on the APRS network is actually
an instance of APRSD that can provide a list of HAM repeaters in the area of the
callsign that sent the message.


Ham radio operator using an APRS enabled HAM radio sends a message to check
the weather.  An APRS message is sent, and then picked up by APRSD.  The
APRS packet is decoded, and the message is sent through the list of plugins
for processing.  For example, the WeatherPlugin picks up the message, fetches the weather
for the area around the user who sent the request, and then responds with
the weather conditions in that area.  Also includes a watch list of HAM
callsigns to look out for.  The watch list can notify you when a HAM callsign
in the list is seen and now available to message on the APRS network.



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

To install ``aprsd``, use Pip:

``pip install aprsd``

Example usage
==============

``aprsd -h``

Commands
========

Configuration
=============
This command outputs a sample config yml formatted block that you can edit
and use to pass in to ``aprsd`` with ``-c``.  By default aprsd looks in ``~/.config/aprsd/aprsd.yml``

``aprsd sample-config``

::

    └─> aprsd sample-config
    ...

server
======

This is the main server command that will listen to APRS-IS servers and
look for incomming commands to the callsign configured in the config file

::

    └─[$] > aprsd server --help
        Usage: aprsd server [OPTIONS]

          Start the aprsd server gateway process.

        Options:

Web Admin Interface
===================
To start the web admin interface, You have to install gunicorn in your virtualenv that already has aprsd installed.

::

  source <path to APRSD's virtualenv>/bin/activate
  pip install gunicorn
  gunicorn --bind 0.0.0.0:8080 "aprsd.wsgi:app"

The web admin interface will be running on port 8080 on the local machine.  http://localhost:8080



Development
===========

* ``git clone git@github.com:craigerl/aprsd.git``
* ``cd aprsd``
* ``make``

Workflow
========

While working aprsd, The workflow is as follows:

* Checkout a new branch to work on by running

  ``git checkout -b mybranch``

* Make your changes to the code
* Run Tox with the following options:

  - ``tox -epep8``
  - ``tox -efmt``
  - ``tox -p``

* Commit your changes. This will run the pre-commit hooks which does checks too

  ``git commit``

* Once you are done with all of your commits, then push up the branch to
  github with:

  ``git push -u origin mybranch``

* Create a pull request from your branch so github tests can run and we can do
  a code review.


Release
=======

To do release to pypi:

* Tag release with:

  ``git tag -v1.XX -m "New release"``

* Push release tag:

  ``git push origin master --tags``

* Do a test build and verify build is valid by running:

  ``make build``

* Once twine is happy, upload release to pypi:

  ``make upload``


Docker Container
================

Building
========

There are 2 versions of the container Dockerfile that can be used.
The main Dockerfile, which is for building the official release container
based off of the pip install version of aprsd and the Dockerfile-dev,
which is used for building a container based off of a git branch of
the repo.

Official Build
==============

``docker build -t hemna6969/aprsd:latest .``

Development Build
=================

``docker build -t hemna6969/aprsd:latest -f Dockerfile-dev .``


Running the container
=====================

There is a ``docker-compose.yml`` file in the ``docker/`` directory
that can be used to run your container. To provide the container
an ``aprsd.conf`` configuration file, change your
``docker-compose.yml`` as shown below:

::

     volumes:
         - $HOME/.config/aprsd:/config

To install plugins at container start time, pass in a list of
comma-separated list of plugins on PyPI using the ``APRSD_PLUGINS``
environment variable in the ``docker-compose.yml`` file. Note that
version constraints may also be provided. For example:

::

    environment:
        - APRSD_PLUGINS=aprsd-slack-plugin>=1.0.2,aprsd-twitter-plugin
