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
This sounds similar to my last approach. If you can select using Lua or the builtin functionality on a per-glyph or even per-font basis, the helper should not be that important, even if providing it might be useful anyway.
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 ...
This was more about printing an error if someone tries it instead of dumping a font which calls random code whenever a delimiter is used... Marcel
