From the same Root.

==============
Cognate 0.0.1
==============

Welcome to **Cognate**, a package designed with making it easy to create
component services. **Cognate** strives to ease the burden of configuration
management and logging configuration, by providing the infrastructure.
**Cognate** fosters component service architectures by making the design,
implementation, and testing of services less of a chore.

A sample hello world component:

from cognate.component_core import ComponentCore
import sys

class HelloWorld(ComponentCore):
def __init__(self, name='World', **kwargs):
self.name = name

ComponentCore.__init__(self, **kwargs)

def cognate_options(self, arg_parser):
arg_parser.add_argument(
'--name',
default=self.name,
help='Whom will receive the salutation.')

def run(self):
self.log.info('Hello %s', self.name)


if __name__ == '__main__':
argv = sys.argv
service = HelloWorld(argv=argv)
service.run()

Allows for the executable:

$ python hello_world.py -h
usage: hello_world.py [-h] [--service_name SERVICE_NAME]
[--log_level {debug,info,warn,error}]
[--log_path LOG_PATH] [--verbose] [--name NAME]

optional arguments:
-h, --help show this help message and exit
--service_name SERVICE_NAME
This will set the name for the current instance.
This will be reflected in the log output.
(default: HelloWorld)
--log_level {debug,info,warn,error}
Set the log level for the log output. (default: error)
--log_path LOG_PATH Set the path for log output. The default file created
is "<log_path>/<service_name>.log". If the path
ends with a ".log" extension, then the path be a
target file. (default: None)
--verbose Enable verbose log output to console. Useful for
debugging. (default: False)
--name NAME Whom will receive the salutation. (default: World)

> pip install cognate

Source
-------

The latest stable release source of **Cognate** can be found on the master
branch at https://github.com/neoinsanity/cognate/tree/master.

For the latest development code, use the develop branch at
https://github.com/neoinsanity/cognate. Please note that the development branch
may change without notification.

To install **Cognate** from source utilize the *setup.py*:

> python setup.py install

Project Development
====================

If you are interested in developing **Cognate** code,
utilize the helper scripts in the *cognate/bin* directory.

Setup the Development Environment
----------------------------------

Prior to running the dev setup scripts, ensure that you have *virtualenv*
installed. All setup commands are assumed to be run from the project root,
which is the directory containing the *setup.py* file.

Prep the development environment with the command:

> bin/dev_setup.sh

This command will setup the virtualenv for the project in the
directory */venv*. It will also install the **Cognate** in a develop mode,
with the creation of a development egg file.

Enable the Development Environment
-----------------------------------

To make it easy to ensure a correctly configured development session,
utilize the command:

> . bin/enable_dev.sh

or

> source bin/enable_dev.sh

Note that the script must be sourced, as it will enable a virtualenv session
and add the *bin* directory scripts to environment *PATH*.

Running Tests
--------------

To run the unit tests:

> run_tests.sh

A BUILD/COVERAGE_REPORT directory will be generated with the test coverage
report. To view the report, open index.html in the generated directory in
a browser.

Building Documentation
-----------------------

To run the documentation generation:

> doc_build.sh

A BUILD//doc/build directory will be generated with the documentation. To
view the documentation, open index.html in the generated directory in
a browser.
