Backgrounds has changed in latest lmtx

Backgrounds has changed in latest lmtx

[Thomas A. Schmitz via ntg-context]

Hi everybody,

With the latest lmtx, my page backgrounds don’t work any more. I think Otared mentioned that the simpleslides module is having problems. I’m trying to figure out what is happening, but I don’t see any warnings or errors, just unexpected results (which is not a good thing). I’m starting with the fundamentals. Here is a fairly minimal example: compile with context --luatex to see the expected result and with lmtx to see what is wrong.

All best

Hi Thomas,

Your example does indeed show the issue I had reported on with Simpleslides: the backgrounds of the slides are not as expected.
So it seems that beginning with version 2022-10-15 something has changed with Metapost or the background mechanism.

Best regards: Otared

Re: Backgrounds has changed in latest lmtx

[Thomas A. Schmitz via ntg-context]

Here comes another one that works with the switch --luatex but not in lmtx:

\setuppapersize[A6,landscape][A6,landscape]

\startuseMPgraphic{ornament}
StartPage ;

save diff ;numeric diff;
diff = .3cm ;

save w; numeric w;
w = xpart (lrcorner Field[Text][Text] - llcorner Field[Text][Text]) - diff ;

save factor; numeric factor;
if NOfPages <= 1 :
   factor = w ;
else :
   factor = w/(NOfPages - 1) ;
fi ;

save p; path p ;
p = unitsquare xyscaled (diff,diff)
                shifted (xpart llcorner Field[Text][Text],0.85cm) ;

for i = 1 upto NOfPages:
   if RealPageNumber = i:
     fill p xyscaled (0,2) shifted ( (i-1)*factor,-diff-0.85cm)
          withcolor blue ;
   else :
     fill p shifted ( (i-1)*factor, 0)
          withcolor red ;
   fi ;
endfor ;
StopPage ;
\stopuseMPgraphic

\defineoverlay
   [Ornament]
   [\useMPgraphic{ornament}]

\setupbackgrounds[page]
		 [state=repeat,
		  background={Ornament}]

\starttext

\dorecurse {10} {Test \page}

\stoptext

All best

Ah sorry, I missed that! It runs with my test file now, thanks! But my 
real file dies with this error:

fatal lua error:

which appears to be related to the new math code?

It works here. Are you sure that you updated to the latest? (There was
a few updates lately)

I have just update to

current version: 2022.10.22 11:23

so I think that's the latest. Minimal example:

\definefontfamily [test] [serif] [Times]
\definefontfamily [test] [sans]  [Helvetica]
\definefontfamily [test] [mono]  [DejaVu Sans Mono] 
[rscale=0.9,features=none]
\definefontfamily [test] [math]  [XITS Math]

\starttext

Test

\stoptext

Hi Thomas,

Both your examples typeset fine with my installation of LMTX (version 2022.10.22 11:23) on MacOS 11.7.
(Indeed you previous file test file reporting the background issue is typeset fine also).

Best regards : Otared

Thanks, Otared - that's bizarre. I just tried both on linux64 and macos 
(12.6, arm): run install.sh, reload font cache and run context without 
the luatex switch on the minimal example with the XITS Math font, and on 
both systems, I get the error that I have sent this afternoon. Can you 
try after rebuilding the font cache?

Thanks

Thomas

FWIW I get the error too on linux64.

OK, found it. File 
lmtx/tex/texmf-context/tex/context/fonts/mkiv/xits-math.lfg

is missing the lines

local common  = fonts.goodies.load("common-math.lfg")
local presets = common.mathematics.tweaks.presets

at the beginning of the file. However, math is typeset in Latin Modern. 
But that's for the math people to see...

All best

Mikael: we have to make mkxl variants of typescript where we replace 
xits by stix .. for the todo.

Re: Backgrounds has changed in latest lmtx

[Otared Kavian via ntg-context]

Hi Thomas,

Sorry for answering too late… Meanwhile you found the culprit :-)

Anyway, I cleaned the cache, did a rebuild and typeset your example files. They do typeset, but as you pointed out the math font is from LMR, not Stix as you specified.

Best regards: Otared
