new mkiv beta

new mkiv beta

[Hans Hagen]

Hi,

I uploaded a beta release. The biggest change is that image inclusion in 
mkiv has changed. Currently it's still some mix of tex and lua code, and 
the backend code is somewhat messy (and not complete yet) but it's a 
first step towards lua doing things. This will only work with a e recent 
luatex.

The advantage is that file searching in lua is more robust (and when 
many search paths are used, also faster). Image conversion has been 
moved to lua too, but currently still uses pdftops (also for svg) but 
that may move to lua as well. Figure libraries are supported by default 
now.

I testes just a few short examples and noticed the following things:


1. XeTeX has two problems with the greep pattern files (lang-agr.pat).

(c:/w32tex/share/texmf-local/tex/context/patterns/lang-agr.pat
! Nonletter.
l.1486 ß╝Ç2╬¢1¤ë╬┤¤àß┐¢

?
! Nonletter.
l.2327 ß╝É3¤â2╬┐¤àß┐¢

?


2. Subpagenumbering did no work with MKIV but you forgot to add
   "\let\immediatesavetwopassdata\savetwopassdata"
   to core-two.mkii


Greetings,

Wolfgang

Not for me, this did only happen with XeTeX.

I guess, you said that last time, too.
Can you give me any hints at what I should look on my side?
If I delete that pat file, everything runs through; if it comes back  
with the next update, it stops again.
Is my pdfTeX too old (Version 3.141592-1.40.3 (Web2C 7.5.6) on OSX  
10.4)?

I can create pdftex formats from the latest beta, using pdftex which is 
almost same as yours (on Ubuntu Hardy)

l.1486 ἀ2ν1ωδυ´

The problematic pattern seems to be
    ἀ2ν1ωδυ´
but its source (line 1194 of grahyph4.tex) is
    >a2n1wdu'
and the other source of problems seems to be in line 2739 of grahyph4.tex:
    >e3s2ou'

I don't understand - what does an accent do at the end of the word in
patterns anyway? Does the accent at the end hold any special meaning?
Or should it be ignored? Fixed in original file perhaps?

Re: new mkiv beta

  Thank you Mojca, it seems to make sense all of a sudden: I think those
two accents are simply a mistake, and we should replace the <upsilon, accent>
sequence by the appropriate Unicode character.  That's what Alexej Kryukov
has done in his antomega package (see lines 1271 and 1816 of TeX Live's
texmf-dist/tex/lambda/antomega/ograhyph4.tex).  Thomas?

  Do you really install the ConTeXt minimals directly in your root
directory?  ;-)

That was my guess too, and I simply remapped those two patterns. They  
are simple typos:

> l. 1739 >e3s2ou': should have been >e3s2o'u
> l. 1194 >a2n1wdu': should have been >a2n1wd'u

With the nifty remap feature, we can just substitute the correct value.

Thanks for investigating!

Hi Hans,

there appears to be a bug in the new image inclusion: my images are  
only found when I give the extension explicitly. So this does work:

\externalfigure[aegean.png]

while this doesn't:

\externalfigure[aegean]

(Glad I don't have to write about Greek patterns for a change...)

the original patterns are buggeds, so in ctxtools (where we generate the 
utf patterns used by context) we do some 'corrections' and it seems that 
we have to do even more of them (btw, the original patterns are meant 
for specific 8 bit encodings)

Re: new mkiv beta

>> new beta

  The Greek patterns look better now, but you should probably add
ἀ2ν1ωδύ and ἐ3σ2ού (where the last character is U+03CD GREEK SMALL
LETTER UPSILON WITH TONOS and not U+1F7B GREEK SMALL LETTER UPSILON WITH
OXIA).  This makes a duplicate entry for these patterns, but all the
other patterns with oxia are duplicated as well.

Which version of luatex is needed? I have

This is LuaTeX, Version snapshot-0.20.2-2008011414

and while generating formats, I get

! LuaTeX error /home/adityam/texmf/tex/context/base/core-inc.lua:85: 
attempt to index global 'img' (a nil value).
\ctxluabytecode ...ode " .. "#1" .. str) end end }

\registerctxluafile ...{\the \luabytecodecounter }
                                                   \fi \fi
l.14 \registerctxluafile{core-inc}{1.001}

I downloaded the svn source, compiled by running build.sh and copied 
luatex into the bin directory and created synlinks for texlua and texluac.

Now I get

loading : Context Core Macros / Figure Handling
! LuaTeX error /home/adityam/texmf/tex/context/base/core-inc.lua:213: 
attempt to call method 'tohash' (a nil value).
\setfigurepathlist ...cation ","\@@exdirectory ")}

It is, I probably messed up something while doing a manual update of the 
binaries.

Hi Hans,

there is also another bug in combination with floats.

\starttext

\placefigure
  {A black rule}
  {\blackrule}

\stoptext

The extra number after the float is insert by "\dofloatinfomessage" in
page-flt.tex and this did happen because you added the \setmessagetext
in the last beta and the command has only two parameters, not three as
use below.

\def\dofloatinfomessage#1#2#3%
  {\bgroup
   \showmessage\m!floatblocks{#2}{#3}%
   \setmessagetext\m!floatblocks{#2}{#3}%
   \@EA\floatinfo\@EA#1\@EA{\currentmessagetext}%
   \egroup}

Hi Hans,

I tried my example for nested section environments with mkiv xml setup
and noticed it is broken again :-(

this is good news. :)

the bad news is, that figure libraries are currently broken in mkiv 
(beta from 29.2). i'll make a minimal example.

ok; btw, don't load fig library modules!, it's supposed to work by 
default; loaded libraries probably spoil the game
