Project description


In what follows python is an alias for python3.7 or pypy3.7 or any later version (python3.8, pypy3.8 and so on).


Install the latest pip & setuptools packages versions

python -m pip install --upgrade pip setuptools


Download and install the latest stable version from PyPI repository

python -m pip install --upgrade reprit


Download the latest version from GitHub repository

git clone
cd reprit


python install


Let's suppose we are defining a class and we want to have __repr__, that:

  1. Includes parameters involved in instance creation. For simple cases it should be possible to copy string & paste in some place (e.g. REPL session) and have similar object definition with as less work as possible. This helps a lot during debugging, logging, in failed test cases with randomly generated data, etc.
  2. In case of signature change method should handle this automatically for simple cases like renaming/removing/changing order of parameters.

This can be done like

>>> from reprit.base import generate_repr
>>> class DummyContainer:
...     def __init__(self, positional, *variadic_positional, keyword_only, **variadic_keyword):
...         self.positional = positional
...         self.variadic_positional = variadic_positional
...         self.keyword_only = keyword_only
...         self.variadic_keyword = variadic_keyword
...     __repr__ = generate_repr(__init__)

after that

>>> DummyContainer(range(10), 2, 3, keyword_only='some', a={'sample': 42})
DummyContainer(range(0, 10), 2, 3, keyword_only='some', a={'sample': 42})

or for a class with avoidance of built-in names clash & private'ish attributes & both

>>> from reprit import seekers
>>> from reprit.base import generate_repr
>>> class State:
...     def __init__(self, id_, name, zip_):
... = id_
...         self._name = name
...         self._zip = zip_
...     __repr__ = generate_repr(__init__,
...                              field_seeker=seekers.complex_)

after that

>>> State(1, 'Alabama', 36016)
State(1, 'Alabama', 36016)

We can also tell to skip unspecified optional parameters

>>> from reprit.base import generate_repr
>>> class Employee:
...     def __init__(self, name, email=None, manager=None):
... = name
... = email
...         self.manager = manager
...     __repr__ = generate_repr(__init__,
...                              skip_defaults=True)

After that

>>> Employee('John Doe')
Employee('John Doe')
>>> Employee('John Doe',
...          manager=Employee('Jane Doe'))
Employee('John Doe', manager=Employee('Jane Doe'))
>>> Employee('John Doe', '', Employee('Jane Doe'))
Employee('John Doe', '', Employee('Jane Doe'))

Note: this method doesn't automatically handle changes during runtime (e.g. if someone deletes instance field or replaces __init__/__new__ method implementation), in this case user should update __repr__ method as well.


Bumping version


Install bump2version.


Choose which version number category to bump following semver specification.

Test bumping version

bump2version --dry-run --verbose $CATEGORY

where $CATEGORY is the target version number category name, possible values are patch/minor/major.

Bump version

bump2version --verbose $CATEGORY

This will set version to major.minor.patch-alpha.


Test bumping version

bump2version --dry-run --verbose release

Bump version

bump2version --verbose release

This will set version to major.minor.patch.

Running tests

Install dependencies

python -m pip install -r requirements-tests.txt
