# Introduction
|
|
Welcome, fellow programmer, to the house of `frozendict` and
|
|
[deepfreeze](#deepfreeze-api)!
|
|
|
|
`frozendict` is a simple immutable dictionary. It's fast as `dict`, and
|
|
[sometimes faster](https://github.com/Marco-Sulla/python-frozendict#benchmarks)!
|
|
|
|
Unlike other similar implementations, immutability is guaranteed: you can't
|
|
change the internal variables of the class, and they are all immutable
|
|
objects. Reinvoking `__init__` does not alter the object.
|
|
|
|
The API is the same as `dict`, without methods that can change the
|
|
immutability. So it supports also `fromkeys`, unlike other implementations.
|
|
Furthermore, it can be `pickle`d, un`pickle`d and have a hash, if all values
|
|
are hashable.
|
|
|
|
You can also add any `dict` to a `frozendict` using the `|` operator. The result is a new `frozendict`.
|
|
|
|
# Install
|
|
|
|
You can install `frozendict` by simply typing in a command line:
|
|
|
|
```bash
|
|
pip install frozendict
|
|
```
|
|
|
|
The C Extension is optional by default from version 2.3.5. You can make it mandatory using:
|
|
|
|
```bash
|
|
CIBUILDWHEEL=1 pip install frozendict
|
|
```
|
|
|
|
On the contrary, if you want the pure py implementation:
|
|
|
|
```bash
|
|
FROZENDICT_PURE_PY=1 pip install frozendict
|
|
```
|
|
|
|
# API
|
|
|
|
## frozendict API
|
|
The API is the same of `dict` of Python 3.10, without the methods and operands which alter the map. Additionally, `frozendict` supports these methods:
|
|
|
|
### `__hash__()`
|
|
|
|
If all the values of the `frozendict` are hashable, returns a hash, otherwise raises a TypeError.
|
|
|
|
### `set(key, value)`
|
|
|
|
It returns a new `frozendict`. If key is already in the original `frozendict`, the new one will have it with the new value associated. Otherwise, the new `frozendict` will contain the new (key, value) item.
|
|
|
|
### `delete(key)`
|
|
|
|
It returns a new `frozendict` without the item corresponding to the key. If the key is not present, a KeyError is raised.
|
|
|
|
### `setdefault(key[, default])`
|
|
|
|
If key is already in `frozendict`, the object itself is returned unchanged. Otherwise, the new `frozendict` will contain the new (key, default) item. The parameter default defaults to None.
|
|
|
|
### `key([index])`
|
|
|
|
It returns the key at the specified index (determined by the insertion order). If index is not passed, it defaults to 0. If the index is negative, the position will be the size of the `frozendict` + index
|
|
|
|
### `value([index])`
|
|
Same as `key(index)`, but it returns the value at the given index.
|
|
|
|
### `item([index])`
|
|
Same as `key(index)`, but it returns a tuple with (key, value) at the given index.
|
|
|
|
## deepfreeze API
|
|
|
|
The `frozendict` _module_ has also these static methods:
|
|
|
|
### `frozendict.deepfreeze(o, custom_converters = None, custom_inverse_converters = None)`
|
|
Converts the object and all the objects nested in it, into their immutable
|
|
counterparts.
|
|
|
|
The conversion map is in `getFreezeConversionMap()`.
|
|
|
|
You can register a new conversion using `register()` You can also
|
|
pass a map of custom converters with `custom_converters` and a map
|
|
of custom inverse converters with `custom_inverse_converters`,
|
|
without using `register()`.
|
|
|
|
By default, if the type is not registered and has a `__dict__`
|
|
attribute, it's converted to the `frozendict` of that `__dict__`.
|
|
|
|
This function assumes that hashable == immutable (that is not
|
|
always true).
|
|
|
|
This function uses recursion, with all the limits of recursions in
|
|
Python.
|
|
|
|
Where is a good old tail call when you need it?
|
|
|
|
### `frozendict.register(to_convert, converter, *, inverse = False)`
|
|
|
|
Adds a `converter` for a type `to_convert`. `converter`
|
|
must be callable. The new converter will be used by `deepfreeze()`
|
|
and has precedence over any previous converter.
|
|
|
|
If `to_covert` has already a converter, a FreezeWarning is raised.
|
|
|
|
If `inverse` is True, the conversion is considered from an immutable
|
|
type to a mutable one. This make it possible to convert mutable
|
|
objects nested in the registered immutable one.
|
|
|
|
### `frozendict.unregister(type, inverse = False)`
|
|
Unregister a type from custom conversion. If `inverse` is `True`,
|
|
the unregistered conversion is an inverse conversion
|
|
(see `register()`).

## deepfreeze examples
|
|
```python
|
|
import frozendict as cool
|
|
|
|
from frozendict import frozendict
|
|
from array import array
|
|
from collections import OrderedDict
|
|
from types import MappingProxyType
|
|
|
|
class A:
|
|
def __init__(self, x):
|
|
self.x = x
|
|
|
|
a = A(3)
|
|
|
|
o = {"x": [
|
|
5,
|
|
frozendict(y = {5, "b", memoryview(b"b")}),
|
|
array("B", (0, 1, 2)),
|
|
OrderedDict(a=bytearray(b"a")),
|
|
MappingProxyType({2: []}),
|
|
a
|
|
]}
|
|
|
|
cool.deepfreeze(o)
|
|
# frozendict(x = (
|
|
# 5,
|
|
# frozendict(y = frozenset({5, "b", memoryview(b"b")})),
|
|
# (0, 1, 2),
|
|
# frozendict(a = b'a'),
|
|
# MappingProxyType({2: ()}),
|
|
# frozendict(x = 3),
|
|
# ))
|
|
|
|
```
|
|
|
|
# Building
|
|
You can build `frozendict` directly from the code, using
|
|
|
|
```
|
|
python3 setup.py bdist_wheel
|
|
```
|
|
|
|
The C Extension is optional by default from version 2.3.5. You can make it mandatory by passing the environment variable `CIBUILDWHEEL` with value `1`
|
|
|
|
On the contrary, if you want the pure py implementation, you can pass the env var `FROZENDICT_PURE_PY` with value `1`
|
|
