the manual: 1.3.3 Example virtual font
Thank you, going to look at it!
Now I have something working. If somebody is interesting see
attachment. PDF output from both pdftex and luatex (on pdfcsplain
format) is exactly same.
Hans & Mojca, it is correct way?
you need to do the ligatures and kerns too
Snip from my lua code:
local characters = {}
for uni, cs in pairs(csbase) do
if f.characters[cs] then
characters[uni] = {}
for key, val in pairs(f.characters[cs]) do
characters[uni][key] = val
end
characters[uni].commands = {{ 'char', cs }}
end
end
Inner for loop should copy whole structure of font with ligatures and
kerns, or not?
Or is something more needed for ligatures and kerns?
you need to remap the kerns hash keys as well as ligatures hash keys O
chained chars too
> Will hyphenation works correctly?
if it's unicoded, yes
New virtual font has defined unicode chars (as commands to other chars),
so it is unicoded, right?
yes
Anyway, in the next context distribution upload (context also ships with
a plain variant) I have added a loader script. If you use luaotfload you
probably have to wait for an update at their end. The luatex-plain
format that ships with context can do this then:
\font\foo=file:luatex-plain-tfm.lua:tfm=csr10;enc=csr;pfb=csr10 at 12pt
\foo áäčďěíĺľňóôŕřšťúýž fiets ff ffi
\bye
(It uses a few helpers from the existing font code, like cached loading
and glyph names to unicode mapping using the enc file which saves
resources and is also more generic than hard coded font vectors. It's
still a pitty that these csr fonts don't come as a full package like plr
which has afm files too; in which case the regular afm/pfb loader could
be used instead. I only tested csr10.tfm / csr10.pfb / css.enc as I
don't want to install the whole lot.
