I think I mentioned this recently but a useful trick when using a filter to convert most code spans/blocks into raws or something else is to use a dummy class `.code` on those which don't have any other class(es) and shouldn't be converted:
``````lua
local function no_code_class (it) return it ~= 'code' end
function Code (elem)
-- Skip if it has any classes
if 0 < #elem.classes then
-- Remove the 'code' class
elem.classes = elem.classes:filter(no_code_class)
return elem
else
-- Do whatever you want with a "bare" Code e.g.
return pandoc.RawInline(SOME_FORMAT, elem.text)
end
end
``````
