humidifier

Create human-friendly IDs from strings.

The typical use case for humidifier is that you have some string (a word, a name, a phrase...) that you want to turn into a human-friendly ID. For example, your project has URLs containing IDs, and it would be nicer to have /record/an-example instead of /record/21937218. Such IDs are easy to remember and can function as a preview for the database entry. This can be achieved with the excellent python-slugify, to which humidifier adds the option to generate unique IDs

Usage

Using humidifier is rather simple:

from humidifier import humidify

id_1 = humidify("dog", unique=True)  # 'dog'
id_2 = humidify("dog", unique=True)  # 'dog-1'
id_3 = humidify("dög", unique=True)  # 'dog-2'
id_4 = humidify("ʔɚ", unique=True)  # 'null'
id_5 = humidify("ʔɚ", unique=True)  # 'null-1'

If your strings come from different populations that you would like to keep distinct in the generated IDs, there is an optional key argument:

from humidifier import humidify

id_1 = humidify("dog", key="animals", unique=True)  # 'dog'
id_2 = humidify("dog", key="quadripeds", unique=True)  # 'dog'
id_3 = humidify("dög", key="animals", unique=True)  # 'dog-1'
id_4 = humidify("dög", key="animals", unique=True)  # 'dog-2'

If you are working with an existing set of IDs:

from humidifier import Humidifier
hum = Humidifier(["dog"])
hum.humidify("dog", unique=True)  # 'dog-1'

If you only want to generate a new ID for each distinct string:

from humidifier import humidify

humidify("dög")  # 'dog'
humidify("dög")  # 'dog'
humidify("dog")  # 'dog-1'

You can also use any of the arguments described for python-slugify. The arguments max_length for truncating, separator for something other than - in between parts, and replacements may be of particular interest when generating IDs.
