As the topic says.
Topic on Extension talk:Arrays
Unfortunately there isn't. Per ExtArrays.php line 188, the only valid values for the print
option are list
, which prints the input as a simple list, and pretty
, which instead pretty prints it with the last two items separated by and
(or presumably the interface language equivalent, depending on what exactly the $wgLang->listToText()
function does).
If your wiki has Extension:Page Forms installed, you can instead use #arraymap, which allows you to change the delimiter used between the final two items in the array.
