Overview of comments

Use the comment filter to insert comments into a pgn file:
      x = _ attacked by k
      comment ("There are "
               " empty squares in the king's field. They are: "

Use hascomment filter to match comments in the PGN file:

hascomment "Good move"

You can instruct the CQL parser to ignore parts of the CQL file using C-style comments:

  • Anything on a line following // is ignored
  • Anything between the /* and */ sequences is ignored.
For example:
     check // the  part after 'check' is a comment and is ignored
     Q attacks r
    /* These two lines are ignored
      Second line*/
