What the filter "syntaxhighlighter_precode" does?
i’m reversing the syntax highlighter plugin () and in the shortcode_callback method you can find this line of code:
$code = apply_filters( 'syntaxhighlighter_precode', $code, $atts, $tag );
but the filter isn’t added in the source file,
can you explain me why? it might be just an old snippet of code?
Thanks in advance.
