Migration path from wiki.module

So it seems that the liquid module is the de facto standard drupal wiki module, and that's great, i'm glad to see such an effort take place.

I was using the wiki.module in 4.6 and since it doesn't seem to be ported to 4.7 (let alone 5.0!), I have migrated to liquid. I think it would be nice to offer people a migration path from wiki to liquid.

I have produced the following php snippet to convert links in teaser and body. It is *really* not elegant, but it basically does what it should here. I converted around 100 nodes with this script. It could use refactoring and could parse more than just links, but I still think it's a good starting base.

$q = db_query("SELECT nid,body FROM node_revisions WHERE format = 4");

while ($row = db_fetch_object($q)) {
  $matches = array();
  print "updating nid: " . $row->nid . ": ";
  $body = preg_replace('/\[([^|]*)\|([^]]*)\]/', '[\2 \1]', $row->body);
  if ($body != $row->body) {
    $query = "UPDATE node_revisions SET body = '" . db_escape_string($body) . "' WHERE nid = " . $row->nid;
    if (db_query($query)) {
      print "fixed";
    } else {
      print "error: " . db_error();
    }
  } else {
    print "no match";
  }
  print "<br/>";
}

$q = db_query("SELECT nid,teaser FROM node_revisions WHERE format = 4");

while ($row = db_fetch_object($q)) {
  $matches = array();
  print "updating nid: " . $row->nid . ": ";
  $body = preg_replace('/\[([^|]*)\|([^]]*)\]/', '[\2 \1]', $row->teaser);
  if ($body != $row->teaser) {
    $query = "UPDATE node_revisions SET teaser = '" . db_escape_string($body) . "' WHERE nid = " . $row->nid;
    if (db_query($query)) {
      print "fixed";
    } else {
      print "error: " . db_error();
    }
  } else {
    print "no match";
  }
  print "<br/>";
}
