store-var 1

List wrapper, that pickles it on every update

store_var

Wrapper, that stores a list into a file on every list update. A band-aid solution for a small project, when database is an overkill.

from store_var import stored

# Stores to file on first initializaiton
users = stored('users.pickle', [
    {'name': 'Gregory', 'age': 45},
    {'name': 'James', 'age': 37},
])

# Behaves as a list
print(f"There are {len(users)} users") # → There are 2 users

# On each change, storage file is updated
users.append({'name': 'Lisa', 'age': 38})

# ··· After restarting a REPL ···

users = stored('users.pickle')
print(users)
# → stored({'name': 'Gregory', 'age': 45}, {'name': 'James', 'age': 37}, {'name': 'Lisa', 'age': 38})
# Notice, that there are 3 users now

Installation

pip install store_var

Limitations

Wrappers for reverse, sort, copy and deepcopy are not implemented yet. Everything else works and is unit-tested.

Stores data using pickle.

Supports only a lists of picklable objects. Won't store a dict, or a list of lambdas.

Examples

See tests.
