my $snippet = Text::Context->new($text, @keywords);
$snippet->keywords("foo", "bar"); # In case you change your mind
DESCRIPTIONGiven a piece of text and some search terms, produces an object which locates the search terms in the message, extracts a reasonable-length string containing all the search terms, and optionally dumps the string out as HTML text with the search terms highlighted in bold.
newCreates a new snippet object for holding and formatting context for search terms.
keywordsAccessor method to get/set keywords. As the context search is done case-insensitively, the keywords will be lower-cased.
@paras = $self->paras($maxlen)
Return shortened paragraphs to fit together into a snippet of at most $maxlen characters.
as_textCalculates a ``representative'' string which contains the given search terms. If there's lots and lots of context between the terms, it's replaced with an ellipsis.
as_html([ start => <some tag>, end => <some end tag> ])Markup the snippet as a HTML string using the specified delimiters or with a default set of delimiters ("<span class="quoted">").
