Difference between MKIV and MKII

Difference between MKIV and MKII

[Aditya Mahajan]

Hi,

I get significantly different white spaces (and hence page breaks) 
while using mkiv and mkii. Is this expected, or should I try to create 
minimal example exhibiting such "problems"?

yes, maybe a test is better.

Here is a minimal example. The spaces around formulas are more.

\starttext

\dorecurse{10}
{
\input tufte
\startformula
  E = mc^2
\stopformula
\par
}

\stoptext

i have to look into it (i remember that there was a problem with display 
(more nodes dus to directional stuff)

anyhow, the whole spacing model will be redone in mkiv (framework is 
there already)

in the meantime I have also updated my \texmf subtree (LM should be up
to date). Using your example, I now get a

12pt text font with pdftex and
10pt text font with luatex (but 12pt in math mode).

So maybe you have the same problem?

If I remember it right, luatex normally used the OTF variant of LM in my
prior test. Now it's also T1, but with an additional font (this one is
used for the 10pt text) in comparison to pdftex:

lmrroman12-regular (Embedded Subset)
Type: Type1 (CID)
Encoding: Identity-H

Strange. Maybe only some messy font setup on my system.

the lm 12 file says ...

  ["design_size"]=0,
  ["familyname"]="LMRoman12",
  ["fontname"]="LMRoman12-Regular",
  ["fullname"]="LMRoman12-Regular",

so it looks like we have a problem there; in that case mkiv assumes 10pt

  Huh huh, same here. Actually all my cached fonts have design_size = 0
(I have most of the LM fonts, a couple of Gyre families and Adobe Caslon).

that's bad, normally we default to 10pt, which is ok, but for lm ...

i'll cook up a trick

i see. which format is used for "design_size"? i tried "12", but i still
get 10pt. "12pt" gives a compilation warning (using luac); i should use
texluac, right? :D

also: why are the t1 variants used in math mode (E =mc2)? italic (all
but equal sign) and roman (=).

120

but there's also a problem in the loader (in font-otf)


         local designsize = data.designsize or data.design_size or 100
         if designsize == 0 then
             designsize = 100
         end
         tfm.designsize         = (designsize/10)*65536




i'll upload a new zip later

i made a mechanism that can 'repair fonts' so lm is fixed (well, the 
error is intercepted

it took me a minute to see, that the 'or 100' is not obsolete. lua is
