Sorry, I have to explain it again.

This is not an assignment at all. This is for my personal interest for processing text with different coding.

I have tried this using C code instead of scripts but I would prefer script because they are comparatively faster and convenient to put in the pipeline. Moreover, unix scripts are convenient for processing text. Bash shell is the one I use.

There is no actual sample of word list or token list.

To clarify, I would say tokens instead of words and sentence as a set of tokens. I use Ubuntu OS.

Please let me know if you need more details.
Thanks in advance. Smilie

Path::Dispatcher::Rule::Tokens(3pm)			User Contributed Perl Documentation		       Path::Dispatcher::Rule::Tokens(3pm)

NAME
Path::Dispatcher::Rule::Tokens - predicate is a list of tokens SYNOPSIS
my $rule = Path::Dispatcher::Rule::Tokens->new( tokens => [ "comment", "show", qr/^d+$/ ], delimiter => '/', block => sub { display_comment(shift->pos(3)) }, ); $rule->match("/comment/show/25"); DESCRIPTION
Rules of this class use a list of tokens to match the path. ATTRIBUTES
tokens Each token can be a literal string, a regular expression, or a list of either (which are taken to mean alternations). For example, the tokens: [ 'ticket', [ 'show', 'display' ], [ qr/^d+$/, qr/^#w{3}/ ] ] first matches "ticket". Then, the next token must be "show" or "display". The final token must be a number or a pound sign followed by three word characters. The results are the tokens in the original string, as they were matched. If you have three tokens, then "match->pos(1)" will be the string's first token ("ticket"), "match->pos(2)" its second ("display"), and "match->pos(3)" its third ("#AAA"). Capture groups inside a regex token are completely ignored. delimiter A string that is used to tokenize the path. The delimiter must be a string because prefix matches use "join" on unmatched tokens to return the leftover path. In the future this may be extended to support having a regex delimiter. The default is a space, but if you're matching URLs you probably want to change this to a slash. case_sensitive Decide whether the rule matching is case sensitive. Default is 1, case sensitive matching. perl v5.12.4 2011-08-30 Path::Dispatcher::Rule::Tokens(3pm)
