Hi,

btw, you probably noticed that mlist_to_hlist is called recursively so you might use that fact

I had some experiments in this area but it is quite hard to avoid side effects here. Anyway it seems to be the most promising way. Related to this: Strict reading of the manual would imply that node.mlist_to_hlist only accepts 'display' or 'text' as style parameter. While you could emulate everything else by adding style nodes, the implementation accepts other styles too and it seemed to make sense to pass the specific style directly. Is this officially supported?

sure as it is used recursively for all styles

Just in case you are interested in my code I attached a patch I am currently experimenting with which moves this completely into the font and triggers it in `get_delim_box` to avoid interference for "easy"

last night i came to the conclusion that the only feasible plug is in the construction of a compound glyph but then we also need to provide it as helper function i.e. it is more a font related thing than math related (even if it gets triggered by a delimiter

delimiters. It a hack which probably fails completely if you try dumping the font during format generation and it does some mostly untested and improvised reference counting, but for easy cases it seems to work quite reliable.

best forget about dumping that kind of font stuff .. lua states are not dumped and anything lua related to fonts neither ...
