New package: text.spelling

The new text.spelling package provides a wrapper around the pspell extension and provides an easy way to spell-check texts. Here's the basic usage:

<?php 
  $spell= new SpellChecker('en');
  $spell->check('Hello');          // TRUE
  $spell->check('Bahnhof');        // FALSE
  $spell->suggestionsFor('delibrate'); // [ "deliberate", "deliberator", "deliberated", ... ]
?>

To spell-check an entire text, you can use the text.Tokenizer implementations to split up the text into words:

<?php 
  $st= new StreamTokenizer(new FileInputStream(new File('candidate.txt')), " \r\n\t.:,;-"));
  while ($st->hasMoreTokens()) {
    $word= $st->nextToken();
    if (is_numeric($word)) continue;  // Ignore numbers
  
    if (!$spell->check($word)) {
      // Handle misspelled word, e.g. make suggestions, ...
    }
  }
?>
