That should be just 'directives' (no underscore).

Yes. Functions called in the markup cannot use "print" statements
for their output -- instead they have to return a string that PmWiki
can substitute at the appopriate point in the page text. Internally,
PmWiki does all markup conversion prior to outputting any text or
headers (it has to do this since there are markups that can affect
the header output), so if any markup functions execute "print" or
"echo" these will be output before PmWiki does any other output.
If you really need to be using print/echo, then you'll want to
investigate the use of the ob_start() PHP functions to capture output
into a string.
