This +syntax has several disadvantages: it requires a space after directives with no +parameters (such as `\[[pagecount ]]`), and it prohibits spaces in +[[wikilinks|wikilink]]. ikiwiki now provides the `!`-prefixed syntax shown +above as the preferred alternative. However, ikiwiki still supports wikis +using the older syntax, if the `prefix_directives` option is not enabled. +For backward compatibility with existing wikis, this option currently +defaults to off, so ikiwiki supports the old syntax. -- cgit v1.2.3
