ordered, dynamically-expandable dot-access dictionary

Project description

DotMap is a dot-access dict subclass that

  • has dynamic child creation
  • can be initialized with keys
  • easily initializes from dict
  • easily converts to dict
  • is ordered by insertion

The key feature is exactly what you want: dot-access

from dotmap import DotMap
m = DotMap()
m.name = 'Joe'
print 'Hello ' + m.name
# Hello Joe

However, DotMap is a dict and you can treat it like a dict as needed

print m['name']
# Joe
m.name += ' Smith'
m['name'] += ' Jr'
print m.name
# Joe Smith Jr

It also has fast, automatic hierarchy (which can be deactivated by initializing with DotMap(_dynamic=False))

m = DotMap()
m.people.steve.age = 31

And key initialization

m = DotMap(a=1, b=2)

You can initialize it from dict and convert it to dict

d = {'a':1, 'b':2}

m = DotMap(d)
print m
# DotMap(a=1, b=2)

print m.toDict()
# {'a': 1, 'b': 2}

And it has iteration that is ordered by insertion

m = DotMap()

m.people.john.age = 32
m.people.john.job = 'programmer'
m.people.mary.age = 24
m.people.mary.job = 'designer'
m.people.dave.age = 55
m.people.dave.job = 'manager'

for k, v in m.people.items():
        print k, v
print

# john DotMap(age=32, job='programmer')
# mary DotMap(age=24, job='designer')
# dave DotMap(age=55, job='manager')

There is also built-in pprint as dict for debugging a large DotMap

m.pprint()
# {'people': {'dave': {'age': 55, 'job': 'manager'},
#             'john': {'age': 32, 'job': 'programmer'},
#             'mary': {'age': 24, 'job': 'designer'}}}

And many other features involving dots and dictionaries that will be immediately intuitive when used.
