I have been trying to use the newest generic font loader
(luatex-fonts-merged.lua) in the context minimals with luaotfload
in latex.
This mostly worked with one exception: luaotfload-letterspace.lua
reference a value that no longer exists:
"...mf-dist/tex/luatex/luaotfload/luaotfload-letterspace.lua:73:
attempt to index local 'nodepool' (a nil value)".
luaotfload does
local nodedirect = nodes.nuts
local nodepool = nodedirect.pool
local new_kern = nodepool.kern
and uses new_kern here
local kern_injector = function (fillup, kern)
if fillup then
local g = new_glue(kern)
local s = getfield(g, "spec")
setfield(s, "stretch", kern)
setfield(s, "stretch_order", 1)
return g
end
return new_kern(kern)
end
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 forget about the spec subnode which is gone for a while now (but
still faked)
The error goes away when I add this to the fontloader (from an older
version):
nuts.new=direct.new
-- new UF
nuts.pool={}
function nuts.pool.kern(k)
local n=nuts.new("kern",1)
setfield(n,"kern",k)
return n
end
-- end UF
nuts.getprop=nuts.getattr
But I would prefer to change luaotfload-letterspace.lua to use
whatever should be used to get the correct effect. Can someone tell
me how to do it??
