yes, i decided to limit the dependencies ... (also because the kern
allocator was a plug outside context)
you can use:
local new = node.direct.new
local g = new("glue")
setfield(g, "stretch", kern)
setfield(g, "stretch_order", 1)
And what I should do about the "return new_kern(kern)"?
local g = new("kern")
setfield(g,"kern",kern)
I tried various variants and got results from no letterspacing to
"invalid node type id" to " This can't happen (invalid node found in
discretionary)." to a luatex crash:
you can't put glue in discs so your letterspacing code should use kerns,
not glue

local new = node.direct.new

if fillup then
local g = new("glue")
setfield(g, "stretch", kern)
setfield(g, "stretch_order", 1)
return g
end
--return new_kern(kern) --??
