* This class implements a Text_Wiki_Rule to find source text marked as a
* blockquote, identified by any number of greater-than signs '>' at the
* start of the line, followed by a space, and then the quote text; each
* '>' indicates an additional level of quoting.
* @author Paul M. Jones <pmjones@ciaweb.net>
* The regular expression used to parse the source text and find
* matches conforming to this rule. Used by the parse() method.
var $regex = '/\n((\>).*\n)(?!(\>))/Us';
* Generates a replacement for the matched text. Token options are:
* 'start' : the start of a blockquote
* 'end' : the end of a blockquote
* 'level' => the indent level (0 for the first level, 1 for the
* @param array &$matches The array of matches from parse().
* @return A series of text and delimited tokens marking the different
* list text and list elements.
// the replacement text we will return to parse()
// the list of post-processing matches
// $matches[1] is the text matched as a list set by parse();
// create an array called $list that contains a new set of
// matches for the various list-item elements.
// a stack of starts and ends; we keep this so that we know what
// indent level we're at.
// loop through each list-item element.
foreach ($list as $key => $val) {
// $val[0] is the full matched list-item line
// $val[1] is the number of initial '>' chars (indent level)
// $val[2] is the quote text
// we number levels starting at 1, not zero
// get the text of the line
// add a level to the list?
if ($level > count($stack)) {
// the current indent level is greater than the number
// of stack elements, so we must be starting a new
// level. push the new level onto the stack with a
// dummy value (boolean true)...
// ...and add a start token to the return.
while (count($stack) > $level) {
// as long as the stack count is greater than the
// current indent level, we need to end list types.
// continue adding end-list tokens until the stack count
// and the indent level are the same.
// the last line may have been indented. go through the stack
// and create end-tokens until the stack is empty.
while (count($stack) > 0 ) {
// we're done! send back the replacement text.
* Renders a token into text matching the requested format.
* @param array $options The "options" portion of the token (second
* @return string The text rendered from the token options.
$type = $options['type'];
$level = $options['level'];
// set up indenting so that the results look nice; we do this
// in two steps to avoid str_pad mathematics. ;-)
