Parsoid doesn't support editing citation link labels by editing the special [[MediaWiki:cite_link_label_group-XX]] page, usually used to localize the name of a particular citation group.
With the HTML/CSS used by Parsoid, this would be done with sitewide CSS instead of by editing article pages. I believe that the same groups of users with the permission to edit in the MediaWiki namespace would have permissions to edit [[MediaWiki:Common.css]], so this should be an equivalent feature (ie, not require dev access to gerrit in order to localize citation group names).
Waving hands vaguely, if you previously had [[MediaWiki:cite_link_label_group-klingon]] with the contents:
wa' cha' wej loS vagh jav Soch chorgh Hut wa'maH
Then for equivalent behavior in Parsoid you'd need to add the following to [[MediaWiki:Common.css]]:
@counter-style klingon-counter {
system: fixed;
symbols: "wa'" "cha'" "wej" "loS" "vagh" "jav" "Soch" "chorgh" "Hut" "wa'maH";
}
[rel="dc:references"] > [data-mw-group="klingon"] {
counter-reset: klingon-ref 0;
}
[rel="dc:references"]> [data-mw-group="klingon"]::before {
content: counter(klingon-ref, klingon-counter);
}
[rel="dc:references"] > [data-mw-group="klingon"] > span.mw-reflink-text {
display: none;
}FIXME: the above is untested!
(Worth remembering that data-mw-group can't be stripped from read view HTML though without breaking this.)
This phab task is for documenting this transition appropriately on wiki, in tech news, etc. If editors demand, we might need to coordinate migration of MediaWiki:cite_link_label-* articles to appropriate CSS.
@ssastry suggests: "see 2nd column of https://phabricator.wikimedia.org/project/view/5534/ and https://github.com/wikimedia/integration-visualdiff/blob/e51e7f0ecb26bd970fced6c7494125426169476d/lib/parsoid.custom_styles.yaml for various CSS to be added to wiki CSS pages."
