Subject: How to query fonts.handlers
Date: Wed, 6 Feb 2019 09:27:21 +1300 [thread overview]
Message-ID: <bb2a1c26-2b84-ae6a-cbe0-21daabe46ff6@gmail.com> (raw)
In-Reply-To: <7db81e7b-4524-67ed-60c9-7cd68f72ac33@gmail.com>
Dear list,
I am trying to access extra kerning that I have defined using
fonts.handlers.otf.addfeature. Even though I query the kerning from
within a paragraph where the kerning is evidently applied I can't seem
to get the value stored earlier, see the comment in the MWE. What am I
doing wrong?
Cheers, Henri

\startluacode
fonts.handlers.otf.addfeature {
name = "ktest",
type = "kern",
data = {
["t"] = { ["e"] = 500 },
}
}
\stopluacode
\definefontfeature[ktest][ktest=yes]
\definefont[1][Serif*ktest]
\starttext
\1 test \ctxlua{
local fnt = font.current()
local tfmdata = fonts.hashes.identifiers[fnt]
local t = string.byte("t")
local e = string.byte("e")
local kern = fonts.handlers.otf.getkern(tfmdata,t,e)
context(kern) % 0 instead of 500. Why?
}
\stoptext

P.S.: I have posted the same question on the LuaTeX list, but with a
different MWE.
