old style nums

[Idris Samawi Hamid]

Dear gang,

What is the official way to get old style numerals in 11pt in mkiv? I'm  
just using lm.

Thnx in advance!

Best
Idris

It depends what do you want to achieve, local changes can be done with
\os, but this will use numbers from the math font.

Mark IV has a new the new option "fontfeatures" and you can use this
to get the oldstyle numbers from the latin modern OT fonts. Option one
is to redefine \os to use the numbers from the main font, you have to
put the following command in your document,
\def\os{\setfontfeature{oldstyle}}, option two is to write
\setfontfeature{oldstyle} in the preamble of your document and ConTeXt
use oldstyle numbers by default if present in the current font.

There is currently no better way to enable oldstyle number for the
whole document except you define your own typescripts and use them.

That's exactly why \os is almost useless (it messes up itemizations and  
other stuff); better to \switchtotypeface, even for local changes.

You also have to define "oldstyle" :-)

==========================================
% engine=luatex

\definefontfeature
   [oldstyle]
   [mode=node,language=dflt,script=latn,onum=yes,tnum=yes]

\setfontfeature{oldstyle}

\starttext

1234567890

I spent hours today writing and debugging a huge typescript for lm (all  
those optical sizes, since i could not for the life of me get it to  
piggy-back the def's in type-siz). I just got it working flawlessly a few  
minutes ago -- sublime, a work of art even -- then I get your message  
which would have saved me hours of work! I just needed that one command!!!

You're an angel, just wish I got this this morning ;-)

Best wishes
Idris

PS Note that tnum (tabular version) looks better than onum alone, but is a  
function of onum in the font so cannot be invoked unless onum is invoked  
first.

No, you don't have to, because oldstyle is predefined in type-ini.tex,
two other predefined fontfeatures are "default" and "smallcaps" :-)

\definefontfeature[onum][onum=yes]
\definefontfeature[lnum][lnum=yes]
\definefontfeature[tnum][tnum=yes,onum=yes]

Hmm, I assumed the order would be [onum=yes,tnum=yes], or does the order  
not matter?

It did work for me but I got a error message for the next line,

<errormessage>
error: ...2tex/share/texmf-local/tex/context/base/font-otf.lua:2018:
attempt to index field 'description' (a nil value)
.
l.12

?
</errormessage>

My testfile:

01 % engine=luatex
02
03 \definefontfeature
04   [oldstyle]
05   [liga=yes,kern=yes,tlig=yes,trep=yes,onum=yes] % texligatures=yes,texquotes=yes
06
07 \setfontfeature{oldstyle}
08
09 \starttext
10
11 123456789 
12
13 \stoptext

I could set "tlig=no" and the error message vanishes.

I think not in this case, but a few OpenType features disable other
(e.g. onum and lnum) and the order could be in souch a case.

Possibly because the predefined one does not have "mode=node",
which seems important. I get:

error: /opt/tex/texmf-local/tex/context/base/font-otf.lua:2019: attempt 
to index field 'description' (a nil value)

followed by an assertion error.

Taco
