Getting started

Install using

pip install pycases

Now convert a string using the relevant function.

import cases

cases.to_snake("XMLHttpRequest") # returns "xml_http_request"

Details

Word boundaries are defined as follows:

• A set of consecutive Unicode non-letter/number e.g. 'foo _bar' is two words (foo and bar)

• A transition from a lowercase letter to an uppercase letter e.g. fooBar is two words (foo and Bar)

  • The second last uppercase letter in a word with multiple uppercase letters e.g. FOOBar is two words (FOO and Bar)

Some functions accept an optional acronyms argument, which is a mapping of lowercase words to their output. For example:

>>> cases.to_pascal("xml_http_request", acronyms={"xml": "XML"})
'XMLHttpRequest'
>>> cases.to_pascal("xml_http_request", acronyms={"xml": "XML", "http": "HTTP"})
'XMLHTTPRequest'
