Options for all conversions

Stripping punctuation

Punctuation is stripped when doing a case conversion. However, should you wish to keep the punctuation you can do so by passing strip_punctuation=False.

camelcase("Hello, world!", strip_punctuation=False) # output: hello,World!

Delimeter customization

Default delimiters used to denote a token boundary.

DELIMITERS = " -_"

You can pass delims to each case conversion function to specify a custom set of delimiters.

# Use a pipe `|` as the only delimiter.
camelcase("Hello,|world!", delims="|") # output: helloWorld

Behavior

Delimiters

If multiple delimeter characters are identified next to eachother they will be considered as a single delimeter. For example, -_ contains 2 different delimeter characters and is considered a single delimeter.
