Add a filter option

I just found the module and it looks great. Love the concept.

To bridge the gap between being limited to just the blocks, how about adding an option to include these into the content via filter tags. This would allow you to add the maps to almost anything! Here is the implementation that I used to do this on a project that I am working on:

<?php

/**
 * Implementation of hook_filters().
 */
function isis_filter($op, $delta = 0, $format = -1, $text = '', $cache_id = 0) {
  switch ($op) {
    case 'list':
      return array(
        0 => t('Include a google map block.'),
        );

    case 'description':
      switch($delta) {
        case 0: return t('Include a google map block using the tag, [gmap-block:XXX]');
      }

    case 'prepare':
      return $text;

    case 'no cache':
      switch ($delta) {
        case 0:
          return TRUE;
      }
    case "process":
      switch($delta) {
        case 0: return preg_replace_callback('/\[gmap\-block:([^\]]*)\]/', '_isis_gmap_block_replacer', $text);
      }


  }
}

function isis_filter_tips($delta, $format, $long = false) {
  switch($delta) {
    case 0: return t('[gmap-block:XXX] - insert the google map block that has the ID of XXX. For example, [gmap-block:1].');
  }
}

function _isis_gmap_block_replacer($matches) {
  if (is_numeric($matches[1])) {
    module_load_include('content.inc', 'gmap_blocks');
    if ($block = gmap_blocks_content($matches[1])) {
      return $block['content'];
    }
  }
  return '';
}
?>
