[dokuwiki] Search pattern challenge for plugin

I'm trying to use the following syntax:
[reveal className width%|wikitext/]
e.g. [reveal wide 10%|[[link]]/]

I'm struggling with the regex pattern for this. As soon as I throw in the
wiki link, the following pattern doesn't work anymore. I'm setting getSort
to 154. I also tried 1154 as well as 4.

\[reveal[^\r\n\|/\]]*+\|(?=[^\r\n\]/]*/\])

this is I think: find [reveal followed at least by something but not returns
| / ] followed by | then look ahead for any characters except returns ] /
followed by /]

getType = formatting,
getAllowedTypes = substition, protected, disabled, formatting

Can I not do this because of the link syntax?

Any help would be greatly appreciated.
