Project Description
=====
Pyonf
=====
--------------------------------------------------------------------------------------------
Easy configuration parsing for your Python script, using command line argument or YAML file.
--------------------------------------------------------------------------------------------


Quickstart
----------

Content of ``myapp.py``:
::
#!/usr/bin/env python
from pyonf import pyonf

default_configuration = {
'user': 'foo',
'password': 'changeme',
'debug': False
}
conf = pyonf(default_configuration)
print(conf)

Set configuration from command line:
::
$ ./myapp.py --user simfu -d
{'debug': True, 'password': 'changeme', 'user': 'simfu'}

Or from YAML configuration file ``myconfig.yml``:
::
user: simfu
password: secretpass

gives:
::
$ ./myapp.py myconfig.yml
{'debug': False, 'password': 'secretpass', 'user': 'simfu'}

Get script usage:
::
$ ./myapp.py --help
usage: myapp.py [-h] [--debug] [--password PASSWORD] [--user USER] [conf_file]

Configuration file:
conf_file Path to YAML configuration file (optional)

Options:
-h, --help show this help message and exit
--debug, -d turn on "debug"
--password PASSWORD, -p PASSWORD
set "password" value, as str (default is changeme)
--user USER, -u USER set "user" value, as str (default is foo)


Features
--------
- Automatically build a command line or configuration file parser by providing a default configuration
- Support for complex configuration schemes (e.g.: lists, dict of dict of ...), mandatory options
- Default configuration can be provided as Python dict object, YAML string or YAML file
- Compatible with Python 2 & 3


More Examples
-------------

Automatic argparse'ing: help message, short and long parameters
::
$ ./myapp.py --help
usage: myapp.py [-h] [--debug] [--password PASSWORD] [--user USER] [conf_file]

Configuration file:
conf_file Path to YAML configuration file (optional)

Options:
-h, --help show this help message and exit
--debug, -d turn on "debug"
--password PASSWORD, -p PASSWORD
set "password" value, as str (default is changeme)
--user USER, -u USER set "user" value, as str (default is foo)

$ ./myapp.py -u simfu
{'debug': False, 'password': 'changeme', 'user': 'simfu'}

$ ./myapp.py --user simfu
{'debug': False, 'password': 'changeme', 'user': 'simfu'}


Use both configuration file and command line argument (the latter takes precedence)
::
$ ./myapp.py myconfig.yml -d
{'debug': True, 'password': 'secretpass', 'user': 'simfu'}


Multiple input for default configuration
::
# Using a dict
default_configuration = {
'user': 'foo',
'password': 'changeme',
'debug': False
}

# Using a YAML String
default_configuration = """
user: foo
password: changeme
debug: false
"""
conf = pyonf(defaulf_configuration)
print(conf)

# Using a YAML file
default_configuration = "/etc/myapp.conf"
conf = pyonf(defaulf_configuration)
print(conf)


Smart parsing of option type
::
default_configuration = """
user: foo
password: changeme
debug: false
level: 3
"""
conf = pyonf(defaulf_configuration)
print(conf)

i.e.:
::
./myapp.py -l 4 # OK
./myapp.py -l quatre # Will not work, level needs to be an integer

# Boolean option does not need argument, its value will be switched
./myapp.py -d


Complex configuration scheme
::
default_configuration = """
user: foo
password: changeme
suboptions:
param1: value1
param2: value2
"""
conf = pyonf(defaulf_configuration)
print(conf)

set "sub-keys" with:
::
$ ./myapp.py --suboptions-param1 my_new_value

Mandatory options:
::
default_configuration = """
user: foo
password: changeme
debug: false
level: 3
"""
conf = pyonf(defaulf_configuration, mandatory_opts = ['user', 'password'])
print(conf)

you have to defined ``user`` and ``password`` option:
::
$ ./my_app.py
Error: "user" option is not set
