heck is a case conversion library.
This library exists to provide case conversion between common cases like CamelCase and snake_case. It is intended to be unicode aware, internally, consistent, and reasonably well performing.
Word boundaries are defined as the "unicode words" defined in the
unicode_segmentation library, as well as within those words in this manner:
- All underscore characters are considered word boundaries.
- If an uppercase character is followed by lowercase letters, a word boundary is considered to be just prior to that uppercase character.
- If multiple uppercase characters are consecutive, they are considered to be within a single word, except that the last will be part of the next word if it is followed by lowercase characters (see rule 2).
That is, "HelloWorld" is segmented
Hello|World whereas "XMLHttpRequest" is
Characters not within words (such as spaces, punctuations, and underscores) are not included in the output string except as they are a part of the case being converted to. Multiple adjacent word boundaries (such as a series of underscores) are folded into one. ("hello__world" in snake case is therefore "hello_world", not the exact same string). Leading or trailing word boundary indicators are dropped, except insofar as CamelCase capitalizes the first word.
