Context data structure

Project description

vcontext
========

Context is dictionary datastructure with custom access to items.
You can access your data by dot access.
Context does not wrap data in itself, rather just access them. Context has `data` attribute where data is stored.

Let show an example:

context = Context({
'status': 200,
'message': 'OK',
'result': [
{
'user': {
'username': 'phonkee',
'name': 'Peter Vrba'
}
}
]
})

You can access data like this:

assert context['result.0.user.username'] == 'phonkee'
assert context['status'] == 200

Key can have multiple parts. Rules are following:
* string - access to dictionary key or object attribute
* integer - access to list item
* first part must be string (since Context is a dictionary

Context can also be used to build complicated datastructures with ease.
Lets build a structure from previous example:

context = Context()
context['status'] = 200
context['message'] = 'OK'
context['result.0.user.username'] = 'phonkee'
context['result.0.user.name'] = 'Peter Vrba'

assert context.data == {
'status': 200,
'message': 'OK',
'result': [
{
'user': {
'username': 'phonkee',
'name': 'Peter Vrba'
}
}
]
}

Context has also support for delete so let's assume that we use context from previous example:

del context['result.0']
assert len(context['result']) == 0

Isn't that neat small helper for your next projects?
