oldstyle features and typing

oldstyle features and typing

[Aditya Mahajan]

Hi,

While using oldstyle features with mkiv, -- in a typing environment comes 
out as a endash. I would consider this a bug.

For example:

\setfontfeature{oldstyle}
\starttext
\starttyping
-- A  comment 123
\stoptyping

\stoptext

Another interesting feature is that numbers in the typing environmnet come 
out in oldstyle (they look nice, BTW). This is expected, and can be 
avoided by using a complete typescript and loading tt fonts with fefault 
features, and other with oldstyle features. Nevertheless, I find it to be 
an interesting side effect.

Aditya

Since we're speaking about oldstyle numbers, here's an interesting  
little bug in mkiv that has bugged me (no pun intended) for quite some  
time now. Is there a solution to this one too?

in node-ini ... you can play with this change ...


     function nodes.process_characters(head)
--~         if status.output_active then
         if false then
             return head, false -- true

we need to make sure that node lists are only processed once, i.e. when 
the box is being built and this is a left over from previous luatex 
versions where we could not be sure (in the otr the boxes pass by again) 
but i think that by now we have that bit of luatex rather stable
