Chris, this is not defining new syntax entities (like replacing >> with &laquo;), but about recognizing and preserving entities in the source (i.e., if the user types "&#7E;", leave that as "&#7E;" in the HTML output, rather than quoting it to "&amp;#7E;"). Among other things, this gives you a way to programmatically quote text that might be misinterpreted as wiki syntax.

Here is the patch.  Any comments?

Hi all,

I've written a patch that allows &whatever; entities to make it through to HTML. Other &s are quoted as usual. Would this be generally useful? Had someone else done it already?

Thanks,
Eddie

You can define entity codes in conf/entities.local.conf

Personally, I don't think a patch is appropriate, but a syntax plugin would be suitable.

Cheers,

Chris
