# python-benedict
The Python dictionary for humans dealing with evil/complex data.

## Features
-   Full **keypath** support *(using the dot syntax by default)*
-   Many **utility** and **parse methods** to retrieve data as needed *(all methods listed below)*
-   Give **benediction** :) to `dict` values before they are returned *(they receive benedict casting)*
-   Easy **I/O operations** with most common formats: `base64`, `json`, `query-string`, `toml`, `yaml`, `xml`
-   100% **backward-compatible** *(you can replace existing dicts without pain)*

## Requirements
-   Python 2.7, 3.4, 3.5, 3.6, 3.7

## Installation
-   Run `pip install python-benedict`

## Testing
-   Run `tox` / `python setup.py test`

## Usage
`benedict` is a `dict` subclass, so it is possible to use it as a normal dictionary *(you can just cast an existing dict)*.

### Import

```python
from benedict import benedict
```

### Init
Create a new instance:

```python
d = benedict()
```

... or cast an existing `dict`:

```python
d = benedict(existing_dict)
```

If the existing dict keys contain the keypath separator a `ValueError` will be raised.

In this case you should need to use a [custom keypath separator](#custom-keypath-separator).

### Keypath
`.` is the default keypath separator.

```python
d = benedict()

# set values by keypath
d['profile.firstname'] = 'Fabio'
d['profile.lastname'] = 'Caccamo'
print(d) # -> { 'profile':{ 'firstname':'Fabio', 'lastname':'Caccamo' } }
print(d['profile']) # -> { 'firstname':'Fabio', 'lastname':'Caccamo' }

# check if keypath exists in dict
print('profile.lastname' in d) # -> True

# delete value by keypath
del d['profile.lastname']
```

#### Custom keypath separator
You can customize the keypath separator passing the `keypath_separator` argument in the constructor.

```python
d = benedict(existing_dict, keypath_separator='/')
```

### API

#### Keypath methods

-   ##### keypaths

```python
# Return a list of all keypaths in the dict.
d.keypaths()
```

#### Utility methods
These methods are common utilities that will speed up your everyday work.

-   ##### clean

```python
# Clean the current dict removing all empty values: None, '', {}, [], ().
# If strings, dicts or lists flags are False, related empty values will not be deleted.
d.clean(strings=True, dicts=True, lists=True)
```

-   ##### deepcopy

```python
# Return a deepcopy of the dict.
d.deepcopy()
```

-   ##### dump

```python
# Return a readable representation of any dict/list.
s = benedict.dump(d.keypaths())
print(s)
```

-   ##### dump_items

```python
# Return a readable representation of the dict for the given key (optional).
s = d.dump_items(key=None)
print(s)
```

-   ##### filter

```python
# Return a filtered dict using the given predicate function.
# Predicate function receives key, value arguments and should return a bool value.
predicate = lambda k, v: v is not None
d.filter(predicate)
```

#### Parse methods
These methods are wrappers of the `get` method, they parse data trying to return it in the expected type.

-   ##### get_bool

```python
# Get value by key or keypath trying to return it as bool.
# Values like `1`, `true`, `yes`, `on`, `ok` will be returned as `True`.
d.get_bool(key, default=False)
```

-   ##### get_bool_list

```python
# Get value by key or keypath trying to return it as list of bool values.
# If separator is specified and value is a string it will be splitted.
d.get_bool_list(key, default=[], separator=',')
```

-   ##### get_datetime

```python
# Get value by key or keypath trying to return it as datetime.
# If format is not specified it will be autodetected.
# If options and value is in options return value otherwise default.
d.get_datetime(key, default=None, format=None, options=[])
```

-   ##### get_datetime_list

```python
# Get value by key or keypath trying to return it as list of datetime values.
# If separator is specified and value is a string it will be splitted.
d.get_datetime_list(key, default=[], format=None, separator=',')
```

-   ##### get_decimal

```python
# Get value by key or keypath trying to return it as Decimal.
# If options and value is in options return value otherwise default.
d.get_decimal(key, default=Decimal('0.0'), options=[])
```

-   ##### get_decimal_list

```python
# Get value by key or keypath trying to return it as list of Decimal values.
# If separator is specified and value is a string it will be splitted.
d.get_decimal_list(key, default=[], separator=',')
```

-   ##### get_dict

```python
# Get value by key or keypath trying to return it as dict.
# If value is a json string it will be automatically decoded.
d.get_dict(key, default={})
```

-   ##### get_email

```python
# Get email by key or keypath and return it.
# If value is blacklisted it will be automatically ignored.
# If check_blacklist is False, it will be not ignored even if blacklisted.
d.get_email(key, default='', options=None, check_blacklist=True)
```

-   ##### get_float

```python
# Get value by key or keypath trying to return it as float.
# If options and value is in options return value otherwise default.
d.get_float(key, default=0.0, options=[])
```

-   ##### get_float_list

```python
# Get value by key or keypath trying to return it as list of float values.
# If separator is specified and value is a string it will be splitted.
d.get_float_list(key, default=[], separator=',')
```

-   ##### get_int

```python
# Get value by key or keypath trying to return it as int.
# If options and value is in options return value otherwise default.
d.get_int(key, default=0, options=[])
```

-   ##### get_int_list

```python
# Get value by key or keypath trying to return it as list of int values.
# If separator is specified and value is a string it will be splitted.
d.get_int_list(key, default=[], separator=',')
```

-   ##### get_list

```python
# Get value by key or keypath trying to return it as list.
# If separator is specified and value is a string it will be splitted.
d.get_list(key, default=[], separator=',')
```

-   ##### get_list_item

```python
# Get list by key or keypath and return value at the specified index.
# If separator is specified and list value is a string it will be splitted.
d.get_list_item(key, index=0, default=None, separator=',')
```

-   ##### get_phonenumber

```python
# Get phone number by key or keypath and return a dict with different formats (e164, international, national).
# If country code is specified (alpha 2 code), it will be used to parse phone number correctly.
d.get_phonenumber(key, country_code=None, default=None)
```

-   ##### get_slug

```python
# Get value by key or keypath trying to return it as slug.
# If options and value is in options return value otherwise default.
d.get_slug(key, default='', options=[])
```

-   ##### get_slug_list

```python
# Get value by key or keypath trying to return it as list of slug values.
# If separator is specified and value is a string it will be splitted.
d.get_slug_list(key, default=[], separator=',')
```

-   ##### get_str

```python
# Get value by key or keypath trying to return it as string.
# Encoding issues will be automatically fixed.
# If options and value is in options return value otherwise default.
d.get_str(key, default='', options=[])
```

-   ##### get_str_list

```python
# Get value by key or keypath trying to return it as list of str values.
# If separator is specified and value is a string it will be splitted.
d.get_str_list(key, default=[], separator=',')
```
