Naming case conventions parsing and converting tool.

Small and clean, fully typed, zero dependency pure Python 2.7 to 3.13 and probably above.

The package supports detection and conversion between cases:

• snake_case
• camelCase
• PascalCase
• kebab-case
• ALL_CAPS_CASE (aka SCREAMING_SNAKE_CASE)
• Title Case

and more to be added.

Usage

>>> from caseutil import is_snake, to_snake

>>> text = 'Some-Title phrase'
>>> is_snake(text)
False
>>> to_snake(text)
'some_title_phrase'

Command line tool

$ caseutil --case allcaps "hi there"
HI_THERE
$ echo "hi_there\nsee you" | python -m caseutil -c camel
hiThere
seeYou

Supported cases

>>> text = 'Some-Title phrase'

snake_case

>>> from caseutil import is_snake, to_snake
>>> to_snake(text)
'some_title_phrase'
>>> is_snake(to_snake(text))
True

camelCase

>>> from caseutil import is_camel, to_camel
>>> to_camel(text)
'someTitlePhrase'
>>> is_camel(to_camel(text))
True

PascalCase

>>> from caseutil import is_pascal, to_pascal
>>> to_pascal(text)

True

kebab-case

Separators

Phrase separators are non-word characters including underscore, and places where text case is changed from lower to upper. Digits are not treated as separators.

>>> from caseutil import words
>>> words('!some_reallyMESsy text--wit4Digits.3VeryWh3re--')
'some,really,ME,Ssy,text,wit4,Digits,3Very,Wh3re'

Unicode

Only ASCII names are supported. Unicode support is planned.

Plans

• Add more test, explore edge cases
• Add Unicode support (write tests)
• Add more cases
