The following reporters are provided:

• upper-case, lower-case -- alter the letter case of strings
• starts-with?, ends-with? -- match a string against the start or end of another string
• contains-rex? -- search in strings using standard regular expressions, returns a boolean if the regex is found
• rex-replace-first, rex-replace-all -- replaces instances of a regex with a string
• rex-split -- splits the string into a list by a regex
• from-file -- read an entire file into a string with one command
• message-digest-5 -- generate the MD5 hash for a string
• hash-code -- generate the MD5 hash for a string
• from-list -- turns a list into a string
• to-list turns a string into a list, so it can be iterated over with foreach
• trim replaces preceding and trailing spaces.

Run make.

If compilation succeeds, string.jar will be created.

To run the tests in tests.txt, run make test.

To build a release package, run make string.zip.

Ideas for possible additional primitives:

• ascii-code <character> -- returns the ASCII index of the given character (the first character of the string), or 0 for non-ASCII characters
• from-ascii <integer> -- returns the ASCII character corresponding to the given small integer index
• last-index-of <needle> <haystack> -- reports the index of the last occurrence of needle in haystack, or false, if needle does not occur
• split-on-character <string> <single-char-delimiter> -- reports a list by splitting string using the given single character`
• split-on-string <string> <string-delimiter> -- reports a list formed by splitting string using the string-delimiter
• position-regex <regex-needle> <haystack>
