Processing a file that used to typeset successfully now gets the  
error message:

! Undefined control sequence.
\initializenextposition ...dosetpositionpapersize
                                                   {\printpaperwidth }

Is there a fix for this?

the end of spec-mis.tex should look like this

    \let\dosetpositionpapersize\gobbletwoarguments

\fi

\protect \endinput


(i will check the upload for it later)

Thanks, Hans—

the spec-mis.tex I have ends with

     \def\dosetpositionplus#1#2#3#4#5%
       {\pdfsavepos
        \dolazysavepositionplus
          {#1}%
          {\noexpand\realfolio}%
          {\noexpand\the\dimexpr\pdflastxpos\scaledpoint\relax}%
          {\noexpand\the\dimexpr\pdflastypos\scaledpoint\relax}%
          {#2}{#3}{#4}{#5}}

\fi

\protect \endinput

I tried changing the end of spec-mis.tex as you suggest, but  
processing still fails with the same error message.

Nope—and that’s why it didn’t work. (Sigh) All is well now that  
I have.

Many thanks for your help!

Hi Norbert,

context_2007.01.12-1 has this problem.  You might want to pull it until
a new package is available as this problem is a bit of a showstopper.

Too late. Is this known upstream? Taco, Hans?

Is this a side-effect of context 2007.01.12 demanding pdftex 1.40?

It's the problem Hans diagnosed as material missing from the end of
spec-mis.tex .  He said he would upload a new zip but I don't know
if that has happened yet.

Damned, this is seriously hosed ... one time I couldn't test all the
test cases I have on my laptop before uploading the upstream stuff is
hosed, that is a pity.

Guys, if you manage to get a fixed upstream by tomorrow 7:20am I can do
an upload ...., otherwise you have to wait till monday morning, because
I am leaving for ice climbing.

In the meantime please install
	http://www.tug.org/texlive/Debian/context/context_2007.01.02-2_all.deb
to get a working context ...

Sorry ...

Best wishes

There was a new upload at 6pm, but I have not yet tested if that fixes
it.

When I upgraded to 2007.01.12 01:02 via the Debian package, I got the
same error that others have reported.  I just tested 2007.01.12 15:56
and the problem is fixed, so thanks for the quick work.  Here is the
test file (same as I've been using for dvipos), and it showed the
problem in dvi and pdf modes.  I'm using pdftex 1.40.0 (with Taco's
patch for the off-by-one-error) in /usr/local/bin.

============================================================
\defineoverlay [foregraphics] [\positionoverlay{foregraphics}]
\setupbackgrounds
  [page]
  [background={foreground,foregraphics}]

\starttext

\hpos{r23}{7} \quad \hpos{r24}{8} 

\startMPpositiongraphic{mypos:line}
  mpprocset := 0;  % context doesn't yet handle the new mpprocsets
  path pa, pb, pab ; numeric na, nb ;
  initialize_box(\MPpos{\MPvar{from}}) ;
  na := nxy ; pa := llxy..lrxy..urxy..ulxy..cycle ;
  initialize_box(\MPpos{\MPvar{to}}) ;
  nb := nxy ; pb := llxy..lrxy..urxy..ulxy..cycle ;
  if na=nb :
    pab := center pa -- center pb ;
    pab := pab cutbefore (pab intersectionpoint pa) ;
    pab := pab cutafter (pab intersectionpoint pb) ;
    pickup pencircle;
    draw pab;
    anchor_box(\MPanchor{\MPvar{from}}) ;
  fi ;
\stopMPpositiongraphic

\startpositionoverlay{foregraphics}
  \setMPpositiongraphic{r23}{mypos:line}{to=r24}
\stoppositionoverlay

The pattern.

that test should go into the test repos (which btw we should get running 
now that it gets filled up); i have to look into that asap

this pos stuff is a bit tricky to support in compatible ways because in a sense it's a backend issue as well as multipass. pdftex and now xetex provide it internally since they kind of are the backends too, which in turn makes it a bit messy to fit into the context special feature driver files, etc etc. We still need the dvipos fallback for aleph.

> that test should go into the test repos 

I've committed it to the contexttest repo as
tex/context/base/supp-mis.tex/test-001.tex

By the way, in dvi mode the file fails unless "mpprocset:=0;" is put in the
\startMPpositiongraphic.  Here's the error msg:

  $ texexec --dvi --nonstopmode tex/context/base/supp-mis.tex/test-001.tex
  // on "TeX run 2"
  ...
  [MP as EPS ./to-dvi-mpgraph.4000] [MP color conversion ./to-dvi-mpgraph.4000
  ! Argument of \dodohandleMPcolor has an extra }.
  <inserted text> 
		  \par 
  <to be read again> 
		     }
  \includeMPasEPS ...\the \!!heightb }\doinsertfile 
						    }\wd \scratchbox \!!widt..

Taco had diagnosed this as due to ConTeXt not handling the new mpost
procsets (hence the mpprocset := 0;).  Not sure why that lack doesn't
hurt the run in pdf mode, but perhaps Taco or Hans understand the
reson.  The test file that I committed does not have the mpprocset:=0,
so it can be used to test for mpprocset handling in dvi mode.

The test skeleton script (./tex/context/base/enco-pfr.tex/Makefile,
which by the way I should move to a more general location) uses only
pdf mode.  I'll move it to a new home and modify it to test dvi mode
as well.

> (which btw we should get running now that it gets filled up); 
> i have to look into that asap

The ./tex/context/base/enco-pfr.tex/Makefile is a start.  But see a
previous email included below.  I still don't see where to get the
known-good comparison PDF (or ps).

  we can think of several tests :

  (1) do they pass
  (2) does the file has the same number of pages
  (3) does a bitmap of the page roughly looks the same

  1/2 would already be great

I have 3 [bitmap checking] pretty much working (see the Makefile in
the repository).  It was a quick hack so is a bit rigid: It tells you
how different the old and new bitmaps are, but a shift of one pixel is
interpreted as "very different" (it doesn't do any dynamic programming
to do the match, just a simple overlay).

For 1 [do they pass], do you mean whether the texexec completes?  That
should be easy as well.

#2 [number of pages] should also be easy, and can be added to #3
pretty easily.  But I still want to know "same number of pages as
which release?"  Because all one has in the repository is .tex source
files, but not known correct PDF or log output from a correct run to
compare against.

Another question is what to do about settings like \runMPgraphics or
\runMPTEXgraphics (and write18).  For example, static MP figures break
(I'm pretty sure) if write18 is on but those other two are off.
Should the test files themselves turn on those variables if they are
needed (i.e. make any changes relative to the default cont-sys.rme)?

[I'll soon visit relatives for the upcoming U.S. long weekend so might
not reply for a few days, depends on how lazy I feel about email.]

supp-,p ssays:

\def\dodohandleMPcolor#1 #2 #3setrgbcolor#4setrgbcolor*\\% old and maybe broken

so, it seems broken indeed; unless someone else solves it i may look at it on a cold winter night (if we ever get one here this year)
