Data::Random::WordList - Perl module to get random words from a word list
my $wl = new Data::Random::WordList( wordlist => '/usr/share/dict/words' );
my @rand_words = $wl->get_words(10);
Data::Random::WordList is a module that manages a file containing a list of
The module expects each line of the word list file to contain only one word. It
could thus be easily used to select random lines from a file, but for
coherency's sake, I'll keep referring to each line as a word.
The module uses a persistent filehandle so that there isn't a lot of overhead
every time you want to fetch a list of random words. However, it's much more
efficient to grab multiple words at a time than it is to fetch one word at a
time multiple times.
The module also refrains from reading the whole file into memory, so it can be
safer to use with larger files.
Returns a reference to a new Data::Random::WordList object. Use the
"wordlist" param to initialize the object:
- wordlist - the path to the wordlist file. If a path isn't
supplied, the wordlist distributed with this module is used.
NUM contains the number of words you want from the wordlist. NUM defaults to 1
if it's not specified. get_words()
dies if NUM is greater than the
number of words in the wordlist. This function returns an array or an array
reference depending on the context in which it's called.
Closes the filehandle associated with the word list. It's good practice to do
this every time you're done with the word list.
