source: bookmarks/trunk/bookmarks.sql @ 15

Last change on this file since 15 was 15, checked in by peter, 11 years ago
  • Bookmarks uses Moose instead of Class::Accessor
  • if not dbh is specified in the Bookmarks constructor, it can use a dbname parameter to create a SQLite DBH
  • the SQLite DBH created form dbname has the foreign_keys pragma set
  • added foreign key constraints to the bookmarks.sql table definitions for bookmarks and tags
  • added a required --file option to bkmk to specify the database file to use
  • added a load command to bkmk that loads bookmarks dumped as YAML using bkmk list
  • Bookmarks::add() can take mtime and id parameters (useful for reconstructing a database from the YAML dump of bkmk list)
  • BookmarkApp and bkmk no longer use DBI directly; just pass a dbname to the Bookmarks constructor
  • changed the default database for BookmarkApp to fk.db (schema from this revision's updated bookmarks.sql, with foreign keys)
