wu-sugar is a small Common Lisp utility library to cut down on keystrokes. It might be similar in spirit to Alexandria, but is very minimalist.

The following functions are defined:

• hash: creates a hash table, analogous to vector or list
• str: like (concatenate 'string ...), but accepts non-string arguments
• join: concatenates strings, joining them by a separator character
• split: splits a string (e.g. a comma-separated string)
• starts-with-p: tests if a sequence begins with a particular subsequence
• ends-with-p: tests if a sequence ends with a particular subsequence
• file-to-string: reads a file's contents into a string
• string-to-file: writes a string's contents into a file
• format-universal-time-iso: a format function to print iso/rfc dates
• universal-time-to-iso: returns an iso/rfc formatted date string
