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([ max_len => 100])

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>", max_len => 100 ])

Markup the snippet as a HTML string using the specified delimiters or with a default set of delimiters (<span class="quoted"> and </span>).
