API Docs

isBlank checks if a string is null, empty or made of whitespace characters.

isEmpty checks if a string is null or empty.

isNotEmpty checks if a string is not null and not empty.

equalsIgnoreCase checks if two strings are equal, ignoring case.

compareIgnoreCase compares two strings, ignoring case.

reverse reverses the order of characters in a string.

nullToEmpty turns null to empty string, and returns non-empty strings unchanged.

emptyToNull turns empty string to null, and returns non-empty strings unchanged.

loop allows you to loop through characters in a string starting and ending at arbitrary indices. Out of bounds indices allow you to wrap around the string, supporting a number of use-cases, including:

• Rotating: loop('lohel', -3, 2) => 'hello'
• Repeating, like repeat, but with better character-level control, e.g.: loop('la ', 0, 8) => 'la la la' // no tailing space
• Tailing: loop('/path/to/some/file.txt', -3) => 'txt'
• Reversing: loop('top', 3, 0) => 'pot'
