About
------------------

This is a "fork" of the "python replacement for java.util.Properties" recipe
on ASPN: <http://code.activestate.com/recipes/496795/> and uploaded by
Anand Balachandran Pillai.

The project is maintained by Jesse Noller <jnoller@gmail.com>, Anand Pilla

What this is
------------------
This module is designed to be a python equivalent to the `java.util.Properties <http://java.sun.com/j2se/1.5.0/docs/api/java/util/Properties.html>`_ class.
Currently, the basic input/output methods are supported, and there are plans
to add the XML input/output methods found in J2SE 5.0.

Fundamentally, this module is designed so that users can easily parse and
manipulate Java Properties files - that's it. There's a fair number of us
pythonistas who work in multi-language shops, and constantly writing your own
parsing mechanism is just painful. Not to mention Java guys are notoriously
unwilling to use anything which is cross-language for configuration, unless
it's XML, which is a form of self-punishment. :)

Plans
------------------
Here is a rough plan of features:

- Keep/maintain blank lines and comments found in the original file
- Make the module compatible with the new methods in J2SE 5.0
- Switch to/add python property access rather than direct dictionary get/set
- Add unit tests
- Add unicode support
- When-Pigs-Fly: If running within Jython, switch to java.util.Properties
under the hood
- Coercion/conversion to python types for values

Usage
------------------
This is the easy part::

from pyjavaproperties3 import Properties
p = Properties()
p.load(open('test2.properties'))
p.list()
print p
print p.items()
print p['name3']
p['name3'] = 'changed = value'
print p['name3']
p['new key'] = 'new value'
p.store(open('test2.properties','w'))

See also the Properties.list() method, which will return an iterator over the
property keys

Changes & News
--------------
0.6:
- Fix license, whitespace.

0.4:
- Patch from Pepper Lebeck-Jobe for handling ! style comments.

0.3:
- Keys that are added which were not part of the original file
are simply appended to the index. Shenanigans.

0.2:
- Added an internal list (self._keyorder) to keep an ordered index of keys
as they are encountered, so the file can we written-back out in the
same order.

0.1:
- Initial release/fork.
- Added setup/packaging and doc
- added in {foo} style references for previous properties, thanks to N B
on ASPN.
