Hello,
I am starting with LuaTeX and I have problem to find the relevant
documentation about \font primitive. There is only one document
http://www.luatex.org/talks/print-plain-tug-2009.pdf
page 7. It seems that the \font primitive works like in XeTeX.
No, \font works more or less like in pdftex. But there is a
"callback" where you can insert lua-code (a "font-loader") to expand
its capabilities.
One existing font loader is luaotfload so try this:
\input luaotfload.sty
\font\aa="[lmroman10-regular]"
\aa text
\bye

Thanks for your answer.
I am developing plainTeX macros. The solution which loads some sty file
and starts loading 18 another .sty files (!!) to solve one SIMPLE problem
is not compatible with plainTeX philosophy. If \tracingall is set then
more than 8000 lines of log is produced.
So, I have perfromed some reverse engeneering to extract the lua code and
there is a result:
--------------
\directlua{luatexbase = luatexbase or {}
luatexbase.luatexversion = \the\luatexversion\space
luatexbase.luatexrevision = \luatexrevision\space
require('luatexbase.attr')
require('luatexbase.cctb')
require('luatexbase.modutils')
oriwrite = texio.write_nl % I don't need to see unusual info
function texio.write_nl(...) end
require('luatexbase.mcb')
luatexbase.require_module('lualibs')
luatexbase.require_module('luaotfload')
texio.write_nl = oriwrite % return to original meaning
}
\font\aa="[lmroman10-regular]"
\aa text
\end
-------------
Now, the \tracingall produces only 255 lines and the core of the problem
is shown. Why this is not documented?
