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">").
