7.2.67 Text::Abbrev - Create an Abbreviation Table from a List

use Text::Abbrev;

%hash = ();
abbrev(*hash, 

LIST

);

The abbrev() routine takes each string in LIST and constructs all unambiguous abbreviations (truncations) of the string with respect to the other strings in LIST . Each such truncation (including the null truncation consisting of the entire string) is used as a key in %hash for which the associated value is the non-truncated string.

So, if good is the only string in LIST beginning with g , the following key/value pairs will be created:

g    => good,
go   => good,
goo  => good,
good => good

If, on the other hand, the string go is also in the list, then good yields these key/value pairs:

goo  => good,
good => good

and go yields only:

go => go
