one of the crystal programming language’s greatest strengths is the ease with which you can work with c apis and external libraries without leaving crystal. you can even implement callbacks in crystal!
in sqlite you can define new functions—callable from sql—with sqlite3_create_function
by providing a name and a callback that implements the function. i created a new function called strip, entirely in crystal, that removes html markup and leaves text. it can be used in a sql query like so:
select * from objects\r\nwhere strip(content) like \"%term%\"
it’s part of the recently released content filtering code.
