Thread:Extension talk:CharInsert/attributes/reply (2)

And how do I implement it? I think the charinsert code has changed significantly since then as https://phab.wmfusercontent.org/file/data/pvsf46w2iksxbyexls2t/PHID-FILE-2jqmm2236ey6seocloyv/fiqy3idcyr2grxam/charinsert-customlabel.patch includes charInsert with inputs ($data, $args) while my version of CharInsert.php includes three function inputs ($data, $params, $parser).
