List utilities

A JVM library to compare two lists, l1 and l1, of objects of any kind.

• version: 1.1.4. Release notes
• requires: java version >= 7

Overview

Use the ListDiff class to find:

• the longest common subsequence (LCS) of the two lists (an ordered intersection of l1 and l2)
• the shortest common supersequence (SCS) of the two lists (an ordered union of l1 and l2)
• the ordered list of items contained only in l1
• the ordered list of items contained only in l2
• differences between l1 and l2

Documentation and maven identifiers

• specifications with concordion tests
• API documentation

CL scripts for printing LCS and SCS of two strings

Groovy scripts with a grapes dependency on listutils to apply LCS and SCS to sequences of characters in two strings:

• lcs.groovy
• scs.groovy

Examples:

 groovy lcs.groovy 'Dr Rock-and-Roll Star' 'Doctor Rock Star'

prints

 Dr Rock Star

while

 groovy scs.groovy 'Dr Rock-and-Roll Star' 'Doctor Rock Star'

prints

 Doctor Rock-and-Roll Star
