Unlike shelve, +many processes can access the database simultaneously. Changing a value in +database is immediately visible to other processes accessing the same database. + +Concurrency is possible because the values are stored in separate files. Hence +the "database" is a directory where *all* files are governed by PickleShare. + +Both python2 and python3 are supported. + +Example usage: + +```python + +from pickleshare import * +db = PickleShareDB('~/testpickleshare') +db.clear() +print("Should be empty:", db.items()) +db['hello'] = 15 +db['aku ankka'] = [1,2,313] +db['paths/are/ok/key'] = [1,(5,46)] +print(db.keys()) +``` + +This module is certainly not ZODB, but can be used for low-load +(non-mission-critical) situations where tiny code size trumps the +advanced features of a "real" object database. + +Installation guide: + +```sh +pip install pickleshare +``` + +Or, if installing from source + +```sh +pip install . +``` + + |
