I want to write a macro that wraps around videoattach.php as a shortcut
for my pmwiki users:

Markup_e('leftvideo', 'directives',
"/\$:leftvideo\\s+(.*?)\\s*:\$/",
“leftvideo(\$m[1])”);

function leftvideo($video_code) {
$output = "(:div class='igrid':) $video_code (:divend:)";
return $output;
}

Weirdly, the “(:divend:)” is treated as text while the rest is
processed correctly. Do you have any
ideas how to do this properly?

First, you should really use Markup() not Markup_e() otherwise your code
will break with recent PHP versions:

Markup_e('leftvideo', 'directives',
"/\$:leftvideo\\s+(.*?)\\s*:\$/",

"leftvideo");

function leftvideo($m) {
$video_code = $m[1];
// ...
}

If your function returns wiki markup, it can call PRR() "PmWiki Redo
Rules" either before returning the markup, or with the return value:

return PRR($output);
