small problem with minimals

small problem with minimals

[Thomas A. Schmitz]

Hi all, esp. Mojca,

I have encountered a small problem with the minimals: some metafun  
stuff that Aditya and I use in our presentation module stopped working  
recently (sorry, I can't tell when exactly). The error message is

!luaTeX error (file lm-rmtt.enc): cannot find encoding file for reading
  ==> Fatal error occurred, no output PDF file produced!
MtxRun | fatal error, code: 70

which is a bit bizarre (I thought luatex didn't use any enc files?).  
Anyway, the same file compiles fine with the same version of ConTeXt  
and luatex under texlive 2008 because there, the enc file is present:

luatools lm-rmtt.enc
/usr/local/texlive/2008/texmf-dist/fonts/enc/dvips/lm/lm-rmtt.enc

Should this file be added to the minimals or is there a different  
problem somewhere down the line? If absolutely necessary, I can make a  
minimal example, but it would take a lot of work...

All best

Thomas

it's probably the fallback font ... how is it used?

In a metafun label (which I can't replace with \sometxt):

label.top(decimal value,origin) ;

forget about sometxt ... that's mojca's personal hack

\starttext

\startMPpage
     numeric value ; value = 123 ;
     label.top(textext(decimal value),origin) ;
\stopMPpage

\stoptext

maybe i should patch the label macro

Maybe that's the reason ...
    decimal value
will be typeset with metapost, while textext will be typeset with TeX.

I have a feeling that Hans defined "lmtt" as default (fallback) font
somewhere in metafun code, so that one gets used.

font-ini.mkii:%     [texnansi-lmtt10]
font-ini.mkii:%     [ec-lmtt10]
font-ini.mkii:%         [texnansi-lmtt10]
font-ini.mkiv:%         [texnansi-lmtt10]
meta-ini.mkii:      defaultfont:="rm-lmtt10";
meta-ini.mkiv:    defaultfont:="rm-lmtt10";
meta-tex.mkii:\definefontsynonym[MPtxtfont][texnansi-lmtt10]

But I have no idea when this has happened. I remember having to add
texnansi-lmtt because of XeTeX complaining of (most probably) exactly
the same thing. There are probably zero benefits if this gets fixed
back.

[unless you work with mkii]

Suggestion that I need to forget XeTeX I guess :) :) :)

That will be great. It will be nice to have label.top("a string") be 
equivalent to label.top(textext("a string")). That will work with both 
mkii and mkiv (and xetex). This way, in MKIV, one can forget about 
\sometxt and textext :-)

only mkiv (ok, i can make some mechanism for mkii using multipass but 
extending mkii has a real low priority)

And how could one change the font/style for the number?

Do you mean with textext, or with the macro that Hans is proposing to 
define?

textext(string) will typeset the string using context, so you can add 
"\switchtobodyfont[whatever]" in there.

The new label macro can use labelfont (or defaultfont, I always forget 
what metapost uses) to switch the font. In that case there should also be 
a label color, unless
draw textext("something") withcolor red ;
works (sorry, I haven't tested this)

I mean in the example from Hans with textext(decimal value).

I prefer \doattributes with a setup command and use this in my modules.

textext("\switchtobodyfont[12pt" & decimal value)

& is the metapost string concat operator (from memory, haven't verified 
this)
