Text::Context(3pm)					User Contributed Perl Documentation					Text::Context(3pm)

NAME

       Text::Context - Handle highlighting search result context snippets

SYNOPSIS

	 use Text::Context;

	 my $snippet = Text::Context->new($text, @keywords);

	 $snippet->keywords("foo", "bar"); # In case you change your mind

	 print $snippet->as_html;
	 print $snippet->as_text;

DESCRIPTION

       Given 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.

   new
       Creates a new snippet object for holding and formatting context for search terms.

   keywords
       Accessor method to get/set keywords. As the context search is done case-insensitively, the keywords will be lower-cased.

   paras
	   @paras = $self->paras($maxlen)

       Return shortened paragraphs to fit together into a snippet of at most $maxlen characters.

   as_text
       Calculates 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">").
