This package provides some generic completion routines that follow the Complete convention. (If you are looking for bash/shell tab completion routines, take a look at the See Also section.) The main routine is 'complete_array_elem' which tries to complete a word using choices from elements of supplied array. For example:

complete_array_elem(word => "a", array => ["apple", "apricot", "banana"]);

The routine will first try a simple substring prefix matching. If that fails, will try some other methods like word-mode, character-mode, or fuzzy matching. These methods can be disabled using settings.

There are other utility routines e.g. for converting completion answer structure from hash to array/array to hash, combine or modify answer, etc. These routines are usually used by the other more specific or higher-level completion modules.
